Design and Development of Integrated pneumatic Car Jack

ABSTRACT

A jack is a device which lifts heavy equipment. The most common form is a car jack, floor jack or garage jack which lifts vehicles so that maintenance can be performed. We make equipment which will lift the vehicle without any manual effort. It is integrated in the vehicle which is simply operated by driver and as per our requirement we lift the wheel.

INTRODUCTION

When car get punctured or broke down, we have to lift it at certain height. Today, we are using hand operated screw jack to lift it. The screw jack is provided by vehicle manufacturer. To lift vehicle, we have to take it out from vehicle, place it properly under axle. Then, by using manual force, screw is to be rotated. The virtues of using a screw as a machine, essentially an inclined plane wound round a cylinder, was first demonstrated Archimedes in 200BC with his screw used for pumping water. There is evidence of the use of screws in the Ancient Roman world but it was the great Leonardo da Vinci in the late 1400’s who first demonstrated the use of a screw jack for lifting loads. With the industrial revolution of the late 18th and 19th centuries came the first use of screws in machine tools from English inventors such as John Wilkinson and Henry Maudsley The most notable inventor in mechanical engineering from the early 1800’s was undoubtedly the mechanical genius Joseph Whitworth. Over the past 60+ years, the product has evolved to push, pull, lift, lower and position loads of anything from a few kilos to hundreds of tonnes. Most features now offered our competitors were actually designed and patented Screw Jack & Duff-Norton over the years

PNEUMATIC JACK

A pneumatic jack is a part of hydraulic jack that is actuated by compressed air – for example, air from a compressor – instead of human work. It saves the effort which exclude the need of the user to actuate the hydraulic mechanism, with potentially increasing speed. In certain circumstances, these jacks are also capable to be operated by normal hydraulic actuation mechanism, by that keeping possession ability, even when source of compressed air is not available.

Design and Development of Integrated pneumatic Car Jack

WORKING PRINCIPLE

1. Firstly we connect hoses as per our figure.

2. When we giving supply to the compressor then compressor will run.

3. At normal condition compressed air is supply at bottom side.

4. The flow control valve is connected to cylinder for controlling the flow.

5. When we want to lift the one rear wheel then we operate the lever of that pneumatic cylinder so that pneumatic cylinder change the position that is it goes to forward condition so that it lift the vehicle.

6. The circular disc is connected to the end of piston.

7. So piston will goes downward and the rear wheel goes upward

8. In that way we can lift the wheel as per requirement.

CONCLUSION

This integrated pneumatic car jack is highly desirable jack to become available in vehicles that can be operated by the compressed air. It is highly useful for pregnant lady, old age people. To design easy to operate. To manufacture Low cost working prod
