Steer Axle for Forklift - The classification of an axle is a central shaft for rotating a wheel or a gear. Where wheeled motor vehicles are concerned, the axle itself can be connected to the wheels and turn together with them. In this particular instance, bushings or bearings are provided at the mounting points where the axle is supported. Conversely, the axle can be connected to its surroundings and the wheels may in turn revolve all-around the axle. In this case, a bushing or bearing is located within the hole in the wheel to be able to enable the wheel or gear to revolve all-around the axle.
Whenever referring to trucks and cars, some references to the word axle co-occur in casual usage. Usually, the word refers to the shaft itself, a transverse pair of wheels or its housing. The shaft itself turns together with the wheel. It is usually bolted in fixed relation to it and known as an 'axle shaft' or an 'axle.' It is likewise true that the housing surrounding it that is usually referred to as a casting is likewise referred to as an 'axle' or occasionally an 'axle housing.' An even broader definition of the word means every transverse pair of wheels, whether they are connected to one another or they are not. Thus, even transverse pairs of wheels in an independent suspension are frequently referred to as 'an axle.'
In a wheeled vehicle, axles are an important component. With a live-axle suspension system, the axles serve in order to transmit driving torque to the wheel. The axles likewise maintain the position of the wheels relative to one another and to the vehicle body. In this particular system the axles must even be able to bear the weight of the vehicle together with whichever cargo. In a non-driving axle, like for instance the front beam axle in various two-wheel drive light vans and trucks and in heavy-duty trucks, there would be no shaft. The axle in this particular situation works only as a steering part and as suspension. Various front wheel drive cars have a solid rear beam axle.
There are different types of suspension systems where the axles serve just to transmit driving torque to the wheels. The position and angle of the wheel hubs is a function of the suspension system. This is normally seen in the independent suspension found in nearly all new sports utility vehicles, on the front of various light trucks and on most brand new cars. These systems still consist of a differential but it does not have fixed axle housing tubes. It could be attached to the vehicle frame or body 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 similar to a full floating axle system as in they do not support the motor vehicle weight.
Lastly, in reference to a vehicle, 'axle,' has a more ambiguous classification. It means parallel wheels on opposing sides of the vehicle, regardless of their mechanical connection kind to one another and the vehicle frame or body.
