About Car Axles

As we all know, the purpose of a machine is to make things easier by controlling force and distance, changing the direction of the force. A simple machine comprised of wheel and axle is made up of two circular objects of different sizes. The prime focus of this page is to offer useful information about car axle

So, what is car axle? Let us find out. The wheel, which is the larger object, turns about a smaller object called an axle. As the wheel is larger than the axle, it always moves through a longer distance than the axle. Therefore, a force when applied to the wheel gets multiplied when transferred to the axle, which travels a shorter distance than the wheel.

Getting on with the info on car axles, it is actually a central shaft for a rotating wheel or gear. The axle of the car may be fixed in position with a bearing or bushing, which sits inside the hole in the wheel or gear, thus allowing the wheel or gear to rotate around the axle. In other cases the, you will see the wheel or gear fixed to the axle. The bearings or bushings are provided at the mounting points where the axle is supported

Details on car axle revel that axles are an integral structural component of a wheeled vehicle. While maintaining the position of the wheels relative to each other and to the vehicle body, the axles must stand the weight of the car plus any cargo. As the wheels are the only part touching the ground, the axles must also bear with the acceleration and braking forces.

 Depending on the design of the vehicle, the car axles serves one or more of the following purposes.

 

Drive: What is important about car axle is that they form an integral part of the drivetrain, comprising of a motor, exerting a rotational force on the axle, which gets transferred to the wheels, so as to accelerate the vehicle.

 

Braking: Similarly, when the vehicle needs to be slowed, force is applied to brake the rotation of the axle. Although most vehicles' brakes are part of the wheel assembly and are exerting torque to the wheels directly, the engine braking is effected via the car axle.

Steering: The front axle in most of the vehicles is a steering axle, controlling the direction of the front wheels' rotational axis relative to the body and rear wheels and maneuvering the vehicle.

 

To conclude the info about car axle, remember that the mechanical advantage, which means the number of times a machine, multiplies the effort force. Browse the other sections of the site to get more details about car axles.
