Forklift Steer Axle - Axles are defined by a central shaft which rotates a wheel or a gear. The axle on wheeled motor vehicles could be attached to the wheels and revolved with them. In this situation, bushings or bearings 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 rotate all-around the axle. In this particular instance, a bushing or bearing is placed inside the hole inside the wheel so as to enable the wheel or gear to turn around the axle.
If referring to cars and trucks, some references to the word axle co-occur in casual usage. Usually, the term refers to the shaft itself, a transverse pair of wheels or its housing. The shaft itself turns together with the wheel. It is frequently bolted in fixed relation to it and called an 'axle shaft' or an 'axle.' It is equally true that the housing around it that is usually called a casting is likewise referred to as an 'axle' or at times an 'axle housing.' An even broader definition of the word refers to every transverse pair of wheels, whether they are connected to one another or they are not. Hence, even transverse pairs of wheels within an independent suspension are frequently called 'an axle.'
The axles are an integral component in a wheeled motor vehicle. The axle serves 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 motor vehicle body. In this particular system the axles must also be able to bear the weight of the vehicle together with whichever cargo. In a non-driving axle, as in the front beam axle in various two-wheel drive light trucks and vans and in heavy-duty trucks, there will be no shaft. The axle in this condition serves only as a steering part and as suspension. Numerous front wheel drive cars have a solid rear beam axle.
The axle serves only to transmit driving torque to the wheels in some 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 newer sports utility vehicles and on the front of several new light trucks and cars. These systems still have a differential but it does not have fixed axle housing tubes. It can be connected 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 of all, in reference to a motor vehicle, 'axle,' has a more ambiguous description. It means parallel wheels on opposing sides of the vehicle, regardless of their mechanical connection type to one another and the motor vehicle frame or body.
