Forklift Steer Axles - The classification of an axle is a central shaft utilized for revolving a wheel or a gear. Where wheeled vehicles are concerned, the axle itself can be attached to the wheels and revolve with them. In this case, bearings or bushings are provided at the mounting points where the axle is supported. On the other hand, the axle can be connected to its surroundings and the wheels can in turn rotate around the axle. In this particular case, a bearing or bushing is situated in the hole within the wheel to allow the wheel or gear to turn around the axle.
With trucks and cars, the word axle in several references is used casually. The word generally refers to the shaft itself, a transverse pair of wheels or its housing. The shaft itself revolves with the wheel. It is frequently bolted in fixed relation to it and known as an 'axle' or an 'axle shaft'. It is also true that the housing surrounding it which is usually referred to as a casting is likewise called an 'axle' or at times an 'axle housing.' An even broader definition of the word refers to 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 known as 'an axle.'
In a wheeled vehicle, axles are an essential component. With a live-axle suspension system, the axles function to be able to transmit driving torque to the wheel. The axles also 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 support the weight of the motor vehicle along with whichever cargo. In a non-driving axle, like the front beam axle in some two-wheel drive light vans and trucks and in heavy-duty trucks, there would be no shaft. The axle in this particular situation works just as a steering part and as suspension. Lots of front wheel drive cars have a solid rear beam axle.
The axle works only to transmit driving torque to the wheels in some kinds of suspension systems. The position and angle of the wheel hubs is part of the functioning of the suspension system found in the independent suspensions of newer sports utility vehicles and on the front of various brand new light trucks and cars. These systems still have a differential but it does not have fixed axle housing tubes. It can be fixed to the vehicle body or frame or likewise 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 vehicle weight.
The vehicle axle has a more ambiguous definition, meaning that the parallel wheels on opposing sides of the vehicle, regardless of their type of mechanical connection to one another.
