Steer Axle for Forklift - The classification of an axle is a central shaft for turning a wheel or a gear. Where wheeled motor vehicles are concerned, the axle itself may be connected to the wheels and turn together with them. In this instance, bushings or bearings are provided at the mounting points where the axle is supported. On the other hand, the axle could be connected to its surroundings and the wheels could in turn turn all-around the axle. In this particular situation, a bushing or bearing is situated in the hole inside the wheel to enable the wheel or gear to turn around the axle.
With cars and trucks, the term axle in some references is utilized casually. The term generally means shaft itself, a transverse pair of wheels or its housing. The shaft itself rotates with the wheel. It is normally bolted in fixed relation to it and called an 'axle shaft' or an 'axle.' It is also true that the housing surrounding it that is normally referred to as a casting is likewise known as an 'axle' or occasionally an 'axle housing.' An even broader sense of the word refers to every transverse pair of wheels, whether they are attached to one another or they are not. Thus, even transverse pairs of wheels in an independent suspension are often referred to as 'an axle.'
In a wheeled vehicle, axles are an integral part. With a live-axle suspension system, the axles function so as 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 likewise be able to support the weight of the motor vehicle plus any 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 would be no shaft. The axle in this particular situation serves only as a steering part and as suspension. A lot of front wheel drive cars consist of a solid rear beam axle.
There are different kinds of suspension systems wherein the axles work only to transmit driving torque to the wheels. The angle and position of the wheel hubs is a function of the suspension system. This is usually found in the independent suspension found in nearly all new sports utility vehicles, on the front of many light trucks and on most brand new cars. These systems still have a differential but it does not have attached axle housing tubes. It can be connected to the motor vehicle body or frame or likewise can be integral in a transaxle. The axle shafts then transmit driving torque to the wheels. The shafts in an independent suspension system are similar to a full floating axle system as in they do not support the vehicle weight.
The vehicle axle has a more ambiguous classification, meaning that the parallel wheels on opposing sides of the vehicle, regardless of their type of mechanical connection to one another.
