Structure Of Car Axles

This article will provide a basic overview of about structure of car axle, which has been used on production of vehicles since the origin of the automobile.  While some of the older styles and features of car axle have become obsolete, it is still important to learn about the basic car axle structure, so as to get valuable insight into why the cutting edge car axles of today perform so much better.

Looking at the features of car axle, it is basically made of a straight single rigid shaft connected to a wheel on the left side of the vehicle and to a wheel on the right side. The axis of rotation is common to both wheels and is fixed by the car axle. Such a design of car axle keeps the wheel positions stable under heavy pressures and stress. Therefore,

another plus of this structure of car axle is to be able to support heavy loads.

The structure of straight car axles is also used in trains, for the rear axles of commercial trucks, and on heavy duty off-road vehicles.  A housing, which encloses the length of the axle, further protects the axle, thus reinforcing it.

In split-axle designs of car axle, the wheel on each side is attached to a separate shaft. Modern passenger cars are sent o have split drive axles. The advantage of this design of car axle is that it allows independent suspension of the left and right wheels. This means a smoother ride for the passengers. Even when the suspension is not autonomous, split car axles allow the use of a differential, which permit the left and right drive wheels to drive at different speeds as the automobile turns. This considerably improves traction and thus extends tire life.


Another car axle structure consists of a group of two or more axles situated close together. Such a configuration provides a greater weight capacity than a single axle. These features of car axle are more beneficial for use in Trucks and Semi trailers.
