Introduction

An integrated jack system in automobile

can be operated with a single push button

or by actuating the lever. The function ofthe in built jack system based on

hydraulic fluid motion is to provide simple

mechanism to lift the vehicle consuming

less manual effort as in case of manual

operated jacks either screw jack or

hydraulic jack.

This type of automatic jack will provide ease

of replacing the wheel in case of wheel

breakdown condition. Usually the seniorcitizens, especially

Female drivers who finds so difficulty to

operate jack manually to lift the car .

So, we are going to present an In-builtjack system in cars can be operated

automatically by using hydraulic motion

transmission system which saves our time ,

manpower , and money

Why we are preferring hydraulic

system instead of electric motorsystem? Dc motors are very costly.

Need to setup individual motors on all wheels. Where

we setting only one hydraulic pump. It increases the

cost of application.

It requires high voltage that seems difficult to produce

in 12volt dc battery.

For individual motor on all wheels more space is

required where in hydraulic, force is transferred

through link pipes. Thus saving space.

Need to setup a separate battery and alternater which

increases cost of application.

Why preferring individual jack on all

wheels instead of two jacks in the centre

of front and rear wheel ?

On the angular ground floor, vehicle is lifted on two

jacks is not properly balanced. Weight of the vehicle

can tilt on one side only.

More power required to lift the vehicle on two jacksrather than the four jacks on individual wheels.

Easier to lift the vehicle from corner because more

work is done i.e.(work=force*distance)

Working principle

Firstly when the lever is pressed the

pulley of pump is linked to engine . The

motion is transmitted to pump that takeshydraulic fluid from sump and feeds to

pressure pipe with high pressure then the

pressure valve is pulled, at this action

high pressure fluid is supplied to

individual cylinders through link pipes.

Due to fluid pressure piston is pressed

downward and the car is lifted.

Application

For the experimental purpose we have to choose a cheap type of caron which we can apply our mechanism successfully.

After observing the configuration of some common cars we selectedMARUTI 800 of lower model from experimental point of view.

summary

Laden weight= 1000 kg

Total load acting = 1000*9.81= 9810 Nm/s2

Because the load is acting on four point contacts

Per point load =9810/4= 2452.5Nm/s2( but in actual practice per unit load is lesser than calculated because the whole load is not acting on point but are thedistributed. This thing is acting in our favour of safety)

When the vehicle is lifted lever should released

When we have to lift down the vehicle the reverse puller is pulled. Spring attachedwith the cylinder piston push back oil automatically and oil reverses back to
