Forklift Steer Axle - Axles are defined by a central shaft which turns a gear or a wheel. The axle on wheeled vehicles may be connected to the wheels and turned with them. In this instance, bearings or bushings are provided at the mounting points where the axle is supported. Conversely, the axle could be fixed to its surroundings and the wheels may in turn rotate around the axle. In this case, a bearing or bushing is situated in the hole in the wheel to be able to enable the gear or wheel to turn around the axle.
When referring to cars and trucks, some references to the word axle co-occur in casual usage. Generally, the term means the shaft itself, a transverse pair of wheels or its housing. The shaft itself revolves with the wheel. It is usually bolted in fixed relation to it and known as an 'axle' or an 'axle shaft'. It is also true that the housing around it which is generally referred to as a casting is otherwise referred to as an 'axle' or at times 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. Hence, even transverse pairs of wheels inside an independent suspension are generally called 'an axle.'
The axles are an integral component in a wheeled motor vehicle. The axle serves in order 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 vehicle body. In this particular system the axles should likewise be able to bear the weight of the vehicle together with whichever cargo. In a non-driving axle, like for example the front beam axle in various two-wheel drive light vans and trucks and in heavy-duty trucks, there will be no shaft. The axle in this particular condition serves just as a steering component and as suspension. A lot of front wheel drive cars consist of a solid rear beam axle.
There are various types of suspension systems where the axles work only 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 found in most new sports utility vehicles, on the front of many light trucks and on nearly all new cars. These systems still have a differential but it does not have attached axle housing tubes. It could be connected to the motor vehicle body or frame or likewise 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.
The motor vehicle axle has a more ambiguous definition, meaning that the parallel wheels on opposing sides of the vehicle, regardless of their kind of mechanical connection to one another.
