ABSTRACT

3ydraulic jack system is attached to automobile "ehicle on front and rear part of the chassis# An

automobile hydraulic jack system can be easily attached to all currently manufacture automobile

chassis and frames# (here is a front suspension hydraulic jack that is mounted centrally to the

front suspension of an automobile between its front wheels# (here is also a rear suspension

hydraulic jack that is mounted centrally to the rear suspension of the automobile between its rear

wheels# (he system operates from a compressed fluid reser"oir tank that has connections for the

front and rear car jack outlets# Additional outlets can be added to the compressed fluid reser"oir

tank for connecting a hydraulic lug wrench and another for a tire inflating hose# (he Major

Project entitled >Automated hydraulic jack with air system? Worked on the principal of hydraulic

power and operated by -+ @olt !1 current, sol"es the all major problem of maintenance of all

automobiles specially the hea"y "ehicles like truck and bus# (his work, if implemented, would

definitely help in the maintenance of automobiles and also in sa"ing of time# In this we also add

the automatic air fill up the tire by the air compressor which is operated with the circuit system

that is work fully automatically#

CHAPTER -

INTRODUCTION

3ydraulic jacks work on the basis of Pascals Principle, named for )laise Pascal, who li"ed in

the se"enteenth century# )asically, the principle states that the pressure in a closed container is

the same at all points# Pressure is described mathematically by a 8orce di"ided by Area#

(herefore if you ha"e two cylinders connected together, a small one and a large one, and apply a

small 8orce to the small cylinder, this would result in a gi"en pressure#

-3- Pa%cal@% Pr'c'6al

)y Pascals Principle, this pressure would be the same in the larger cylinder, but since the larger

cylinder has more area, the force emitted by the second cylinder would be greater#

(his is represented by rearranging the pressure formula

PB 8CA, to 8 B PA#

(he pressure stayed the same in the second cylinder, but Area was increased, resulting in a larger

8orce#

%enerally speaking, there is a wiper control knob, with stalls of low speed, high speed and

intermission, on the handle of auto combination switch# (he top of the handle is the key switch,

after pressing which water will erupt to wiper blade, of the scrubber# (he scrubber system,

consisting of plastic water tank D-#.E+ litersF, micro/electric centrifugal water pump, pipes,

spray no==les, is "ery ordinary equipment in automobiles# Water in the tank is supplied through

the pump to +E7 spray no==les, by which it is e4truded into trickles# (hen the trickles are

sprayed onto the windshield glass, to clean the glass with the wiper blade#

3ydraulic :acks are portable de"ices used for raising hea"y objects by means of force applied

with a le"er orscrew# (he hydraulic jacks are compact and lightweight units that are used for

lifting capacities# (hey offer easy operation and are fast acting components# (he hydraulic jacks

come with inbuilt release pedal for rapid lowering and lugs that make it easy to mount# (he

hea"y duty chassis pre"ents the jack from twisting or bending and foot pump pro"ides fast lift to

the load# It also has a safety o"erload "al"e that pre"ents o"erloading beyond rated capacity#

Gnlike the traditional screw type jack which has to be turned with a long handle, the hydraulic

jack uses oil pressure to displace DliftF the "ehicle by mere mo"ing a le"er or handle up and

down# (his is "ery easy to operate and with this e"en a child can operate and lift a "ehicle using

the hydraulic jack#

)oth hydraulic jacks are pi"oted on the rectangular struts# (he one end of jack is fi4ed to frame#

(he rectangular Struts are kept hollow for reducing the weight# (he rectangular paddles are also

pi"oted on the other end of struts# 3ydraulic jacks are operated by -+ "olt !1 battery# At a single

time, one and two both jacks can work and "ehicle can lift from one side and also from two sides

as per the requirement#

A hydraulic jack uses a fluid, which is incompressible, that is forced into a cylinder by a pump

plunger# 2il is used since it is self/lubricating and stable# When the plunger pulls back, it draws

oil out of the reser"oir through a suction check "al"e into the pump chamber# When the plunger

mo"es forward, it pushes the oil through a discharge check "al"e into the cylinder# (he suction

"al"e ball is within the chamber and opens with each draw of the plunger# (he discharge "al"e

ball is outside the chamber and opens when the oil is pushed into the cylinder# At this point the

suction ball within the chamber is forced shut and oil pressure builds in cylinder#+3. H"7ra4l'c >l4'7%

3ydraulic fluids are a large group of fluids used as the moti"e medium in hydraulic machinery#

8luid types include synthetic compounds, mineral oil, water, and water/based mi4tures# (he

fluids are found in machinery and equipment ranging from brakes, power steering systems, and

transmissions to backhoes, e4ca"ators, garbage trucks and industrial shredders# 3ydraulic

systems are "ery common in aircraft flight control systems# 3ydraulic fluids can contain a wide

range of chemical compounds, including& oils, butanol, esters De#g# phthalates, like !*3P, and

abdicate, like bis D+/ ethylhe4ylF adipateF, polyalkylene glycols DPA%F, phosphate esters De#g#

3ydraulic jacks transmit a small mechanical force through one small hydraulic cylinder to a

large hydraulic cylinder# (his results in a large mechanical force e4erted by the larger cylinder

Ddue to Pascal5s principle which states that the pressure in a closed system is the same

e"erywhereF# (his model uses a hand pump to power the smaller hydraulic cylinder# A circular

pipe transmits the hydraulic liquid from the smaller cylinder to the larger cylinder, with a check

"al"e to pre"ent backflow# (he larger cylinder lifts a load# (he mass of the load can be changed

to in"estigate the pressures generated in the hydraulic system#

3ydraulic cylinders get their power from pressuri=ed hydraulic fluid, which is typically oil# (he

cylinder consists of a cylinder barrel, in which a piston connected to a piston rod is mo"ing# (he

barrel is closed by the cylinder bottom and by the cylinder head where the piston rod comes out

of the cylinder# (he piston has sliding rings and seals# (he piston di"ides the inside of the

cylinder in two chambers, the bottom chamber and the piston rod side chamber# (he hydraulic

pressure acts on the piston to do linear work#

A hydraulic cylinder is the actuator or JmotorJ side of this system# (he JgeneratorJ side of the

hydraulic system is the hydraulic pump that brings a fi4ed or regulated flow of oil into the

13


14/35

system# Mounting brackets or cle"ises are mounted to the cylinder bottom as well as the piston

rod# )y pumping hydraulic oil to the bottom side of the hydraulic cylinder, the piston rod starts

mo"ing upward# (he piston pushes the oil in the other chamber back to the reser"oir# If we

assume that the oil pressure in the piston rod chamber is =ero, the force on the piston rod equals

the pressure in the cylinder times the piston area# If the oil is pumped into the piston rod side

chamber and the oil from the piston area flows back to the reser"oir without pressure, the

pressure in the piston rod area chamber is Pull 8orceCDpiston area / piston rod areaF# In this way

the hydraulic cylinder can both push and pull#

WIPER MOTOR

Wiper Motor, the power source of the wiper blade, is the core of the whole wiper system#

(herefore, the quality of the wiper motor must be guaranteed to ensure its performance# (he

wiper motor is a permanent/magnet direct current D!1F one# It is equipped on the front

windscreen glass with the mechanical parts of the worm gear# (he worm gear functions to slow

Windshield wipers are designed and made to clear water from a windshield# (he wiper parts

or claws that are small arms under the wiper# Although the rubber is the familiar part of the

blade, the blade actually includes a metal strip called a blade frame with a slot along the length

of the frame and replacement holes in the frame# A wiper and pi"ot are mounted on brackets at

both ends of a long rod called the connecting link, and, as the force from the motor push# Wiper

Motor and %ear reduction& It takes a lot of force to accelerate the wiper blades back and forth

across the windshield so quickly# In order to generate this type of force, a worm gear is used on

the output of a small electric motor# (he worm gear reduction can multiply the torque of the

motor by about . times, while slowing the output of the electric motor by . times as well# (he

output of the gear reduction operates a linkage that mo"es the hydraulic jack plunger back and

When testing for torque, I found the motor to draw close to -7 amps in a stalled condition# (his

factor must be taken into account when selecting a power supply# Since the motor will only use

what it needs when it comes to current, its best to pro"ide a source with a higher current rating

than you think you might need#

CHAPTER :

RACK AND PINION

A Nrack and pinion5 gears system looks quite unusual# 3owe"er, it is still composed of two gears#

(he Npinion5 is the normal round gear and the Nrack5 is straight or flat# (he Nrack5 has teeth cut in

it and they mesh with the teeth of the pinion gear#

(he pinion rotates and mo"es the rack in a straight line / another way of describing this is to say

Nrotary motion5 changes to Nlinear motion5#

18


19/35

>'!4re :3-2 Rac a7 P''o

A good e4ample of a Nrack and pinion5 gear system can be seen on trains that are designed to

tra"el up steep inclines# (he wheels on a train are steel and they ha"e no way of griping the steel

track# Gsually the weight of the train is enough to allow the train to tra"el safely and at speed

along the track# 3owe"er, if a train has to go up a steep bank or hill it is likely to slip backwards#

A Nrack and pinion5 system is added to some trains to o"ercome this problem# A large gear wheel

is added to the centre of the train and an e4tra track is, with teeth, called a Nrack5 is added to the

track# As the train approaches a steep hill or slope the gear is lowered to the track and it meshes

with the Nrack5# (he train does not slip backwards but it is pulled up the steep slope#

A rack and pinion is a type of linear actuator that comprises a pair of gears which con"ert

rotational motion into linear motion# A circular gear called Jthe pinionJ engages teeth on a linear

JgearJ bar called Jthe rackJO rotational motion applied to the pinion causes the rack to mo"e

relati"e to the pinion, thereby translating the rotational motion of the pinion into linear motion#

8or e4ample, in a rack railway, the rotation of a pinion mounted on a locomoti"e or a railcar engages a rack between the rails and forces a train up a steep slope#8or e"ery pair of conjugate

in"olute profile, there is a basic rack# (his basic rack is the profile of the conjugate gear of

infinite pitch radius#

A generating rack is a rack outline used to indicate tooth details and dimensions for the design of

a generating tool, such as a hob or a gear shaper cutter#

:3- Ac&4a&or

A rack and pinion with two racks and one pinion is used in actuators# An e4ample is pneumatic

rack and pinion actuators that can be used to control "al"es in pipeline transport# (he actuators in

the picture on the right are used to control the "al"es of large water pipeline# In the top actuator,

a gray control signal line can be seen connecting to a solenoid "al"e Dthe small black bo4

attached to the back of the top actuatorF, which is used as the pilot for the actuator# (he solenoid

"al"e controls the air pressure coming from the input airline Dthe small green tubeF# (he output

air from the solenoid "al"e is fed to the chamber in the middle of the actuator, increasing the

pressure# (he pressure in the actuators chamber pushes the pistons away# While the pistons are

mo"ing apart from each other, the attached racks are also mo"ed along the pistons in the opposite

directions of the two racks# (he two racks are meshed to a pinion at the direct opposite teeth of

the pinion# When the two racks mo"e, the pinion is turned, causing the attached main "al"e of

the water pipe to turn#

compressed air can be used for a "ariety of applications, utili=ing the kinetic energy of the air as

it is released and the tank depressuri=es# When tank pressure reaches its lower limit, the air

It5s easy to think of air compressors as a tool that is "ery common howe"er, things were not like

that in the past# In fact not that long ago a compressor isn5t something you would ha"e found in a

workshop or factory#

Instead, tools used in the shop were powered by a centrali=ed source which transferred the power

in "arious ways depending on the tool# Gsually it was through a system of wheels, belts or dri"eshafts# It was a large mechanical system that was way too bulky and way too e4pensi"e, and

therefore only a"ailable to professionals#

$owadays we come across air compressors pretty much e"erywhere# (hey5re common place in

gas stations where we generally use them to inflate tires# (hey can be found in factories,

2f course, the biggest ad"antage of compressors o"er a centrali=ed power source is their small

si=e, and the fact they don5t require a massi"e motor# (hey are also quieter, more durable, and

some of them are highly portable# )ut, I am getting way ahead of myself because you5re here to

find out how air compressors work#

23


24/35

Air compressors function based on a "ery simple principle# When the air is compressed, its

"olume decreases whereas the pressure increases#

(he most common way to achie"e this is with the help of a reciprocating piston# (here are

compressors which employ rotating impellers for the purpose of creating air pressure, but I will

discuss the different types in a separate article# (hose which are built around a reciprocating

piston are more common, and if you5re familiar with how internal combustion engines work, you

will know piston compressors function in a similar manner#

*ach reciprocating piston compressor has a crankshaft, connecting rod, a piston, cylinder, and a

"al"e head# In order for the entire mechanism to work, you need power# Air compressors are

usually powered by electricity or gas depending on the model# Most compressors also ha"e a

tank which is there to store compressed air for the purpose of keeping the air pressure within a

set range while powering "arious air tools#

At the top of e"ery compressor cylinder there is a "al"e head that contains both the inlet and

discharge "al"e which are basically metal flaps# (hese open and close and are located on top of

the "al"e plate# When the piston mo"es down inside the cylinder in the space abo"e the piston a

"acuum is created#

03- Elec&ro'c C'rc4'&

An electronic circuit is composed of indi"idual electronic components, such as resistors,

transistors, capacitors, inductors and diodes, connected by conducti"e wires or traces through

which electric current can flow# (he combination of components and wires allows "arious simple

and comple4 operations to be performed& signals can be amplified, computations can be

performed, and data can be mo"ed from one place to another#

An electric circuit is a set of electrical components that are connected together in a loop with a

power source, that allows current DelectronsF to flow through them# We"e used them to great

to do much of our manual labor, found ways to communicate worldwide, and e"en put a human

Analog electronic circuits are those in which current or "oltage may "ary continuously with time

to correspond to the information being represented# Analog circuitry is constructed from two

fundamental building blocks& series and parallel circuits# In a series circuit, the same current

passes through a series of components#

>'!4re 03-2 A'r >'ll 46 ' T"re

A string of 1hristmas lights is a good e4ample of a series circuit& if one goes out, they all do# In a

parallel circuit, all the components are connected to the same "oltage, and the current di"ides

between the "arious components according to their resistance#

(he basic components of analog circuits are wires, resistors, capacitors, inductors, diodes, and

transistors# DIn +-+ it was demonstrated that memristors can be added to the list of a"ailable

components#F Analog circuits are "ery commonly represented in schematic diagrams, in which

wires are shown as lines, and each component has a unique symbol# Analog circuit analysis

interconnectionsO any resistance or reactance is captured by e4plicitly adding a parasitic element,

such as a discrete resistor or inductor# Acti"e components such as transistors are often treated as

(here are different ways of categori=ing electric circuits# 2ne way is series "ersus parallel

circuits# A series circuit is a circuit where the components are connected in one continuous loop#

A parallel circuit is a circuit where the components are connected in separate branches# Most real

life circuits are combinations of these two concepts, since each type has ad"antages# When

something breaks in a series circuit, the whole circuit stops working# (his doesnt happen with

parallel circuits# A series circuit can therefore be useful for safety features like fuses, but not so

useful for 1hristmas lights# Series circuits are also cheaper to produce#

Another way of classifying circuits is to separate them by power type& direct current D!1F or

alternating current DA1F# !irect current is where the electricity flows in one direction#

Alternating current is where the electricity flows back and forth in both directions, usually

switching 0 times a second#

(he current supplied by wall sockets is A1# (here are a number of reasons for this& for e4ample,

generating A1 electricity is easier, and you can transfer it o"er long distances without losing as

much energy along the way# 3owe"er, many de"ices, especially smaller ones, use !1 current#

Sometimes when a de"ice has a large bo4 as part of its power cord, thats because it is con"erting

A1 current into !1 current# Its much easier to do this in your home on a small scale than at the

power station#

project automatic air compressor system is to be there which is imitated to know the reference

with the "ehicle wheel by @ gear and automated air fill up to the tyre when it drop up to le"el of

+ bar it automatically auto cut off at 6 bar# )ottle or hand jacks, came into wide spread

popularity during the early part of the +th 1entury, paralleling the boom of the automobile

industry# (hey filled the immediate need of a small con"enient de"ice requiring only one person

to operate that could lift an automobile off the ground for ser"icing#

(his is initially to encourage the technique in future which is not to manual#8or applying load

lifting the "ehicle by hydraulic :ack hand is operated with separate pumping unit and is wiper

motor# (his :ack is portable and a"ailable in "arious capacities# (he pumping unit is connected to

the hydraulic jack by means of a rigid connecting flat #. meter long#

CONCLUSION

(he main aim of this project is to implementation of hydraulic jack to a hea"y "ehicleO due to

these hea"y loads on a "ehicle the life the tire will be reduced# Whene"er the "ehicles is static

condition the "ehicles e4erts point load on tire due to this load the wear of the tire takes place# So

that the present of hydraulic jack increases the life of the tire and also it helps in reduction of

transportation cost# And also it helps the user for changing of tires whene"er they were busted or

punctured# 3ydraulic jack system is attached to automobile "ehicle on front and rear part of the

chassis# An automobile hydraulic jack system can be easily attached to all currently manufacture

automobile chassis and frames# (here is a front suspension hydraulic jack that is mounted

centrally to the front suspension of an automobile between its front wheels# (here is also a rear

suspension hydraulic jack that is mounted centrally to therear suspension of the automobile

between its rear wheels# (he system operates from a compressed fluid reser"oirtank that has

connections for the front and rear car jack outlets# Additional outlets can be added to the

compressed fluid reser"oir tank for connecting a hydraulic lug wrench and another for a tire

inflating hose#

A team is simply a group of people who work together to achie"e a common purpose,

1haracteristic of effecti"e team work include the ability to set aside the personal prejudices and

the willingness to take responsibility as a group#

Se%e of P4r6o%e

(eam work is characteri=ed by ha"ing a sense of purpose to achie"e a clear, specific goal that all

members belie"e is important to attain# A team can be assigned to carry out a specific project,

such as seeking ways to impro"e profitability in small business# A team could also be assemble

to find the right candidate for job opening#

Co56e&ec"

All team should consist of members who are capable of contributing to achie"ement of the goal

based on their le"el of knowledge or e4pertise# If a team is assigned the task of de"elopment of

an e4pense, budget, but one or more of the members has little or no budgeting e4perience# (he

whole team will suffer as a result#

Coo6era&'(e %6'r'&

A successful team contains a spirit of cooperation# All members need to work together to achie"e

the specific goal# (his can be difficult, especially if some members possess strong personalities

or are highly opinionated# Successful teams tend to ha"e strong leaders who can keep e"erybody

on the same page while keeping the petty bickering to minimum#

Pla"'! B" &he R4le%

(eam should also ha"e a set of rules that determines its operating procedure# (hese rules help to

keep the team on track and eliminate ambiguities# 8or e4ample, a team might ha"e a rule that all

team members must agree on a decision before it can be implemented# (his would require that

the team deliberate, much in way of a trial jury, until a consensus is reached#

Acco4&a'l'&"

(eams must ultimately be held accountable as a whole for their failures as their successes# As a

business owner, this means you need to reward the team as a whole for its accountable for its

failure# (eam leaders should foster an en"ironment within the team where its members are free to

offer praise and criticism of other members within the idea that team results are what matters, not

indi"idual contributions#
