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
