Steer Axle for Forklifts - The definition of an axle is a central shaft meant for turning a gear or a wheel. Where wheeled vehicles are concerned, the axle itself may be fixed to the wheels and revolve together with them. In this situation, bearings or bushings are provided at the mounting points where the axle is supported. Conversely, the axle may be fixed to its surroundings and the wheels can in turn rotate all-around the axle. In this particular instance, a bearing or bushing is situated in the hole within the wheel to allow the gear or wheel to revolve around the axle.
When 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 revolves with the wheel. It is frequently bolted in fixed relation to it and called an 'axle shaft' or an 'axle.' It is also true that the housing around it that is usually referred to as a casting is otherwise known as an 'axle' or occasionally an 'axle housing.' An even broader definition of the term means every transverse pair of wheels, whether they are attached to one another or they are not. Hence, even transverse pairs of wheels within an independent suspension are generally known as 'an axle.'
The axles are an essential part in a wheeled motor vehicle. The axle works so as 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 motor vehicle body. In this particular system the axles must likewise be able to support the weight of the motor vehicle along with any load. In a non-driving axle, as in the front beam axle in some two-wheel drive light trucks and vans and in heavy-duty trucks, there will be no shaft. The axle in this situation works just as a steering component and as suspension. Several front wheel drive cars consist of a solid rear beam axle.
There are different kinds of suspension systems where the axles work just 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 seen in the independent suspension found in nearly all new sports utility vehicles, on the front of numerous light trucks and on the majority of brand new cars. These systems still consist of a differential but it does not have connected axle housing tubes. It can be connected to the motor 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 vehicle weight.
To finish, with regards to a motor vehicle, 'axle,' has a more vague definition. It means parallel wheels on opposing sides of the motor vehicle, regardless of their mechanical connection kind to one another and the vehicle frame or body.
