We, Mechanical-farm provide BE project ideas for mechanical engineering students. Our list consists of the finest and innovative ideas for mechanical engineering projects. We have widest ideas for final year project for mechanical engineering.
An automotive jack is a device used to raise all or part of a vehicle into the air in order to facilitate repairs. Most people are familiar with the basic car jack (manually operated) that is still included as standard equipment with most new cars. These days, a car jack is an important tool to have in our vehicle due to unknown upcoming event such as flat tire in our journey. Even so, people who like to rotate their tires themselves or who may install snow tires before the winter and remove them in the spring need to use a jack to perform the job. Changing a flat tire is not a very pleasant experience.
In the repair and maintenance of automobiles (car), it is often necessary to raise an automobile to change a tire or access the underside of the automobile. Accordingly, a variety of car jacks have been developed for lifting an automobile from a ground surface. Available car jacks, however, are typically manually operated and therefore require substantial laborious physical effort on the part of the user. Such jacks present difficulties for the elderly and handicapped and are especially disadvantageous under adverse weather conditions.
Furthermore, available jacks are typically large, heavy and also difficult to store, transport, carry or move into the proper position under an automobile. In addition, to the difficulties in assembling and setting up jacks, such jacks are generally not adapted to be readily disassembled and stored after automobile repairs have been completed.
ELECTRIC CAR JACK
The electrically operated jack is the modified jack. It is easy to handle and operate. It is operated through car battery which makes it very comfortable to the users, specially for old age persons and for women. An electric car jack includes a base frame or housing that is adapted to be placed on the ground underneath the automobile to be lifted. The housing includes motors connected to drive arms connected to a load bridge and plate.
The bridge is typically mounted within the drive arms by rods located within slots on the arms enabling the bridge to move upward and downward while being retained within the drive arms. The drive arms typically include drive wheels that rotated and are coupled together by a chain mechanism that assures the coupler moves uniformly.
Typically, the motors are operated by the car’s battery. The drive from the motor transferred to the worm and worm gear which are connected ahead to the driver gear. This driver gear operates the driven gear by chain mechanism. In this way motors drive the arms, lifting and lowering the load bridge which lifts and lowers the automobile.
- Extremely low maintenance required.
- Self contained mechanism with compact design.
- Shock absorbent and silent
