Forklift Steer Axle - Axles are defined by a central shaft that revolves a gear or a wheel. The axle on wheeled vehicles could be attached to the wheels and turned together with them. In this situation, bushings or bearings are provided at the mounting points where the axle is supported. Conversely, the axle can be fixed to its surroundings and the wheels could in turn revolve all-around the axle. In this case, a bearing or bushing is situated within the hole inside the wheel to allow the gear or wheel to revolve all-around the axle.
When referring to cars and trucks, some references to the word axle co-occur in casual usage. Normally, the term means the shaft itself, a transverse pair of wheels or its housing. The shaft itself turns along with the wheel. It is normally bolted in fixed relation to it and called an 'axle shaft' or an 'axle.' It is also true that the housing around it which is generally referred to as a casting is also known as an 'axle' or sometimes an 'axle housing.' An even broader sense of the term means every transverse pair of wheels, whether they are connected to one another or they are not. Hence, even transverse pairs of wheels inside an independent suspension are frequently referred to as 'an axle.'
In a wheeled lift trucks, axles are one important forklift parts. With a live-axle suspension system, the axles work 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 bear the weight of the vehicle along with whatever load. In a non-driving axle, as in the front beam axle in various two-wheel drive light vans and trucks and in heavy-duty trucks, there would be no shaft. The axle in this situation serves only as a steering part and as suspension. Several front wheel drive cars consist of a solid rear beam axle.
The axle serves only to transmit driving torque to the wheels in various types 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 new sports utility vehicles and on the front of many new light trucks and cars. These systems still consist of a differential but it does not have connected axle housing tubes. It could 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 vehicle weight.
To finish, 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.
