Steer Axle for Forklift - Axles are defined by a central shaft which rotates a wheel or a gear. The axle on wheeled motor vehicles may be attached to the wheels and rotated with them. In this case, bushings or bearings are provided at the mounting points where the axle is supported. Conversely, the axle can be attached to its surroundings and the wheels can in turn turn all-around the axle. In this particular instance, a bearing or bushing is positioned within the hole within the wheel so as to allow the gear or wheel to revolve all-around the axle.
When referring to cars and trucks, several references to the word axle co-occur in casual usage. Generally, the word refers to the shaft itself, a transverse pair of wheels or its housing. The shaft itself turns with the wheel. It is usually bolted in fixed relation to it and known as an 'axle' or an 'axle shaft'. It is likewise true that the housing around it that is normally called a casting is likewise called an 'axle' or sometimes 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. Therefore, even transverse pairs of wheels in an independent suspension are generally known as 'an axle.'
In a wheeled motor vehicle, axles are an integral part. With a live-axle suspension system, the axles work so as 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 should also be able to support the weight of the vehicle together with whatever load. In a non-driving axle, like the front beam axle in several two-wheel drive light trucks and vans and in heavy-duty trucks, there would be no shaft. The axle in this particular situation serves only as a steering part and as suspension. Various front wheel drive cars consist of a solid rear beam axle.
The axle works just to transmit driving torque to the wheels in several kinds of suspension systems. The angle and position of the wheel hubs is part of the operating of the suspension system seen in the independent suspensions of new sports utility vehicles and on the front of numerous new light trucks and cars. These systems still have a differential but it does not have attached axle housing tubes. It can be connected to the vehicle frame or body or also 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 motor vehicle weight.
Last but not least, in reference to a motor vehicle, 'axle,' has a more ambiguous classification. It means parallel wheels on opposing sides of the motor vehicle, regardless of their mechanical connection type to one another and the vehicle body or frame.
