Forklift Steer Axles - Axles are defined by a central shaft that revolves a gear or a wheel. The axle on wheeled motor vehicles can be attached to the wheels and rotated with them. In this particular instance, bushings or bearings 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 turn around the axle. In this case, a bearing or bushing is positioned inside the hole within the wheel so as to allow the gear or wheel to rotate around the axle.
Whenever referring to trucks and cars, some references to the word axle co-occur in casual usage. Normally, the word means 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 called an 'axle shaft' or an 'axle.' It is also true that the housing around it which is usually called a casting is also called an 'axle' or occasionally an 'axle housing.' An even broader sense of the word means every transverse pair of wheels, whether they are attached to one another or they are not. Hence, even transverse pairs of wheels in an independent suspension are frequently known as 'an axle.'
In a wheeled vehicle, axles are an essential part. With a live-axle suspension system, the axles work in order to transmit driving torque to the wheel. The axles also maintain the position of the wheels relative to one another and to the motor vehicle body. In this system the axles should also be able to bear the weight of the motor vehicle together with whichever 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 situation works only as a steering part and as suspension. A lot of front wheel drive cars consist of a solid rear beam axle.
There are different types of suspension systems wherein the axles operate just to transmit driving torque to the wheels. The position and angle of the wheel hubs is a function of the suspension system. This is normally found in the independent suspension seen in the majority of brand new sports utility vehicles, on the front of numerous light trucks and on most brand new cars. These systems still have a differential but it does not have attached axle housing tubes. It could be attached to the vehicle frame or body or even can be integral in a transaxle. The axle shafts then transmit driving torque to the wheels. The shafts in an independent suspension system are like a full floating axle system as in they do not support the motor vehicle weight.
Last but not least, with regards to a vehicle, 'axle,' has a more vague definition. 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.
