Steer Axle for Forklifts - The definition of an axle is a central shaft meant for revolving a gear or a wheel. Where wheeled vehicles are concerned, the axle itself may be attached to the wheels and turn with them. In this situation, bearings or bushings are provided at the mounting points where the axle is supported. Conversely, the axle could be attached to its surroundings and the wheels can in turn revolve around the axle. In this particular situation, a bushing or bearing is positioned inside the hole within the wheel to be able to enable the wheel or gear to rotate all-around the axle.
Whenever referring to cars and trucks, several references to the word axle co-occur in casual usage. Normally, the word refers to the 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 referred to as an 'axle' or an 'axle shaft'. It is equally true that the housing surrounding it that is usually known as a casting is otherwise called an 'axle' or at times an 'axle housing.' An even broader sense 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 within an independent suspension are often known as 'an axle.'
In a wheeled motor vehicle, axles are an important part. With a live-axle suspension system, the axles function so as 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 likewise be able to bear the weight of the motor vehicle plus whatever load. In a non-driving axle, as in the front beam axle in several two-wheel drive light vans and trucks and in heavy-duty trucks, there will be no shaft. The axle in this situation works just as a steering component and as suspension. Lots of front wheel drive cars consist of a solid rear beam axle.
The axle works only to transmit driving torque to the wheels in various kinds of suspension systems. The angle and position of the wheel hubs is part of the operating of the suspension system found in the independent suspensions of newer sports utility vehicles and on the front of many brand new light trucks and cars. These systems still have a differential but it does not have connected axle housing tubes. It can be fixed to the motor vehicle frame or body 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.
Last of all, 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 type to one another and the vehicle body or frame.
