Steer Axles for Forklifts - The definition of an axle is a central shaft for rotating a gear or a wheel. Where wheeled motor vehicles are concerned, the axle itself could be attached to the wheels and revolve 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 can be connected to its surroundings and the wheels can in turn turn all-around the axle. In this particular case, a bushing or bearing is placed within the hole within the wheel to enable the gear or wheel to rotate around the axle.
With cars and trucks, the word axle in several references is utilized casually. The term usually means shaft itself, a transverse pair of wheels or its housing. The shaft itself turns along 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 around it which is usually referred to as a casting is otherwise referred to 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 connected to one another or they are not. Hence, even transverse pairs of wheels within an independent suspension are often referred to as 'an axle.'
The axles are an integral component in a wheeled motor vehicle. The axle serves to be able to transmit driving torque to the wheel in a live-axle suspension system. The position of the wheels is maintained by the axles relative to one another and to the vehicle body. In this particular system the axles must even be able to support the weight of the vehicle plus any load. In a non-driving axle, like for instance the front beam axle in several two-wheel drive light vans and trucks and in heavy-duty trucks, there would be no shaft. The axle in this condition serves only as a steering part and as suspension. Numerous front wheel drive cars consist of a solid rear beam axle.
The axle works just to transmit driving torque to the wheels in several types of suspension systems. The position and angle of the wheel hubs is part of the functioning of the suspension system seen in the independent suspensions of newer SUVs and on the front of various new cars and light trucks. These systems still have a differential but it does not have attached axle housing tubes. It can be attached to the 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 similar to a full floating axle system as in they do not support the motor vehicle weight.
Lastly, with regards 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 frame or body.
