This document describes a student project to design and fabricate a hydraulic jack system for vehicles to make maintenance and service easier. It will be operated using a DC motor powered by the vehicle's battery. The system includes a hydraulic pump, reservoir, control unit, and left and right hydraulic jacks. It works based on Pascal's law and fluid power principles to allow small forces over large distances. The self-locking nut feature provides accident avoidance. Benefits include reduced human effort, time savings, and ability to operate when the engine is off. Some challenges are increased costs, weight, and need for battery power. Potential future improvements discussed.

3. INTRODUCTION
 Frequent innovations relates to hydraulic system and more
specifically to an automobile hydraulic jack system.
 Most of the vehicles are lifted by using screw jack. This needs high
man power and consumes a lot of time .
 Various types of jack or lift devices has been installed on for lifting
the vehicle.
 Conventionally we have always used a separate jack for each of 4
wheels , in steed here we have the jacks permanently installed on the
vehicle.
 It is an object of innovation to provide ideal jack system that can be
operated by driver from inside the car.
 It is also an object of innovation to provide an ideal hydraulic system
which is operated by cam mechanism which actuates hydraulic jack
which will lift the vehicle.

4. ABSTRACT
 Transportation has now been increased in wide manner.
 In olden days people used wooden wheel vehicle for
transportation. but nowadays disc wheels are used.
those wheels are covered with tyres
 Our Indian road condition are not comfort to ride the
vechiles.the tyres are met punchers at high rate
 In order to change tyres , they have to lift vehicles by
manual jacks
 Nowadays, hydraulic jacks, pneumatic jacks etc are used
 In our project we had implementing a new concept of
hydraulic jack which consist of pump, cylinder, handle,
ram, self locking nut.

5. PROBLEM DEFINITION
Huge human effort required
Time taking process
Difficulties in repairmen

1. DC battery 12 Volt
2. DC Motor
3. Hydraulic pump
4. Hydraulic Fluid Reservoir
5. Control Unit
6. Hydraulic Jack
6.1Left Side Hydraulic Jack
6.2Right Side Hydraulic Jack
7. Pipes

7. BASIC LAW OF HYDRAULICS
 Pascal's Law:
The principle stating that external
static pressure exerted on a confined
fluid is distributed evenly
throughout the fluid.

8. Cont…
 The relationship between pressure, force and area is
given by
P=F/A
 This relationship is very useful for obtaining a
mechanical advantage

9. FLUID POWER AND ITS APPLICATION
 Fluid power deals with the control and transmission of
energy through the use of pressurized fluids.
 Fluid power is quite literally the force behind industry
because it is used to push, pull, drive and regulate
virtually all machines used in industry.

 Fluid power is used in the steering, brake system, and
automatic transmissions of cars and trucks
 Since fluids exist as either a liquid or a gas, fluid power
is a term used to describe both hydraulics and
pneumatics.

10. PRINCIPLE OF HYDRAULIICS
 The hydraulic lift works on the principle that the effort
required to move something is the product of the force and
the distance the object is moved.
 By using an incompressible fluid to transmit the force, the
hydraulic lift allows a small force applied over a large distance
to have the same effect as a large force applied over a small
distance.
 In this way, a small hand pump may be used to lift an
automobile.
 In order to fill the large cylinder under the car with fluid,
however, the small pump must be operated many, many
times.

11. DIAGRAMATIC REPRESENTATION

12. WORKING
 This machine has a hydraulic cylinder and piston
assembly. Which works in a port type integrated
hydraulic circuit.
 I this circuit there is no need for separate oil pump
hydraulic houses, D.C valves, Pumps etc.
 These all those things are integrated with the hydraulic
cylinder itself.

13. ACCIDENT AVOIDING SYSTEM
 We all are known that hydraulic pump and cylinder has
oil rings and O-rings for operating the hydraulic circuit
 But due to over loading OR fatigue leads to cut off O-
rings and oil seals.
 So un Predictable Accident can be occur due to this .
 so we will provide the bolt and nut principle in this
hydraulic for accident avoiding which is explained in
drawing.
 After lifting the jack we will down the nut upto cylinder
head .
 if any O-ring or oil leakage occurs the nut will provide
the piston to go down

AVOIDING SYSTEM

15. ADVANTAGES
The maintenance of the vehicle will be very easy.
The servicing of the vehicle will be easy and cheap.
Reduces human effort at large extent.
Time saving .
Can be operated even when the vehicle is not in starting
condition.
As it is electrically powered , doesn’t harm vehicle
efficiency.
.

16. POINTS TO OVERCOME
Cost will increase slightly.
Weight of vehicle will increase slightly.
System can not work without 12 volt DC current.
System required maintenance also
Chances of leakage

17. FUTURE SCOOPE
We are currently working on small commercial vehicles
but in future it can be used for heavy duty vehicles by
making small changes.
Further to this each wheel can be accompanied by
hydraulic jack.
Hydraulic pump can directly be connected to engine
output instead of devicing a motor .
With this ,system can be operated through acceleration
pedal.

18. CONCLUSION
 A hydraulic jack is a device used to carry large loads with the application of
small force.
 Here we are going to fabricate a hydraulic jack which is operated using a
DC wiper motor which gets dc supply from the battery of the vehicle
without application of man force.
 Maintenance and service of the vehicle can be easily done by this project.
With this project the usage of automobile can be made easy for women and
old people.
 The inbuilt jack is operated by battery so it can also be used when the
vehicle engine is not started.
 Arrangement is also very useful for heavy loading vehicles and a single
person can go on a long drive.
