Steer Axle for Forklifts - The description of an axle is a central shaft for revolving a wheel or a gear. Where wheeled motor vehicles are concerned, the axle itself can be fixed to the wheels and turn along with them. In this situation, bearings or bushings are provided at the mounting points where the axle is supported. On the other hand, the axle can be attached to its surroundings and the wheels could in turn revolve around the axle. In this particular instance, a bushing or bearing is placed in the hole inside the wheel to allow the wheel or gear to turn around the axle.
Whenever referring to cars and trucks, several references to the word axle co-occur in casual usage. Generally, the term means the shaft itself, a transverse pair of wheels or its housing. The shaft itself turns along with the wheel. It is frequently bolted in fixed relation to it and known as an 'axle shaft' or an 'axle.' It is equally true that the housing around it which is usually called a casting is otherwise called an 'axle' or at times an 'axle housing.' An even broader definition of the term means every transverse pair of wheels, whether they are connected to one another or they are not. Hence, even transverse pairs of wheels inside an independent suspension are frequently known as 'an axle.'
In a wheeled motor vehicle, axles are an integral part. With a live-axle suspension system, the axles work to transmit driving torque to the wheel. The axles even maintain the position of the wheels relative to one another and to the vehicle body. In this particular system the axles should also be able to bear the weight of the motor vehicle together with whichever load. In a non-driving axle, like the front beam axle in various two-wheel drive light trucks and vans and in heavy-duty trucks, there will be no shaft. The axle in this particular condition works only as a steering component and as suspension. Numerous front wheel drive cars consist of a solid rear beam axle.
There are various kinds of suspension systems where the axles serve only to transmit driving torque to the wheels. The position and angle of the wheel hubs is a function of the suspension system. This is often found in the independent suspension seen in most brand new SUV's, on the front of many light trucks and on most new cars. These systems still consist of a differential but it does not have fixed axle housing tubes. It can be attached to the motor vehicle body or frame or also could be integral in a transaxle. The axle shafts then transmit driving torque to the wheels. The shafts in an independent suspension system are like a full floating axle system as in they do not support the motor vehicle weight.
To finish, in reference to a vehicle, 'axle,' has a more ambiguous description. It means parallel wheels on opposing sides of the motor vehicle, regardless of their mechanical connection type to one another and the motor vehicle body or frame.
