The need for a transmission in an automobile is a consequence of the characteristics of the internal combustion engine. Engines typically operate over a range of 600 to about 7000 revolutions per minute (though this varies, and is typically less for diesel engines), while the car’s wheels rotate between 0 rpm and around 1800 rpm. Furthermore,…

Transmission system in a car helps to transmit mechanical power from the car engine to give kinetic energy to the wheels. It is an interconnected system of gears, shafts, and other electrical gadgets that form a bridge to transfer power and energy from the engine to the wheels. The complete setup of the system helps…

The shocks and struts should be check frequently for leakages Ball joints should be checked immediately in case the motion of the car is not right. Make sure to lubricate the ball joints of your car frequently.

1. Vehicle pulling to one side while driving/Alignment Problem – While driving, the wheels have to point in the proper direction because if they aren’t your vehicle’s steering won’t be in the centre, which means that you will lose the right direction, this, in turn, will increase your tyre wear. This alignment issue can be…

1.     Control Arm: A movable lever that fastens the steering knuckle to the frame of the vehicle. 2.     Control Arm Busing: This is a sleeve which allows the control arm to move up and down on the frame. 3.     Strut Rod: Prevents the control arm from swinging forward and backwards. 4.     Ball Joints: A joint that allows the control arm and steering knuckle…

1.  There is a need of a flexible connection between the main frame and the wheels of the vehicle in dynamic condition that enables the relative motion between them without causing deformation to the main structure or any other components of the vehicle. 2.  A suspension system in a vehicle is needed to support the overall…

Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels. Suspension systems serve a dual purpose — contributing to the car’s road holding/handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps,…

Gear teeth are designed so that the number of teeth on a gear is proportional to the radius of its pitch circle, and so that the pitch circles of meshing gears roll on each other without slipping. The speed ratio for a pair of meshing gears can be computed from ratio of the radii of the pitch…

A reverted gear train is very similar to a compound gear train. They are both used when there is only a small space between the input and output shafts and large changes in speed or power are needed. A simple reverted gear train consists of two shafts each of which carry multiple compound spur gears. A…
