Steer Axle for Forklifts - The definition of an axle is a central shaft intended for turning a wheel or a gear. Where wheeled vehicles are concerned, the axle itself may be connected to the wheels and rotate together with them. In this particular instance, 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 may in turn turn around the axle. In this case, a bearing or bushing is positioned in the hole within the wheel to allow the gear or wheel to turn all-around the axle.
Whenever referring to cars and trucks, some references to the word axle co-occur in casual usage. Normally, the word refers to the shaft itself, a transverse pair of wheels or its housing. The shaft itself revolves with the wheel. It is normally bolted in fixed relation to it and known as an 'axle shaft' or an 'axle.' It is also true that the housing around it which is generally called a casting is also called an 'axle' or at times an 'axle housing.' An even broader sense of the term refers to every transverse pair of wheels, whether they are connected to one another or they are not. Hence, even transverse pairs of wheels in an independent suspension are generally known as 'an axle.'
In a wheeled motor vehicle, axles are an essential part. With a live-axle suspension system, the axles work so as 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 likewise be able to support the weight of the vehicle along with any load. In a non-driving axle, like for example the front beam axle in some two-wheel drive light vans and trucks and in heavy-duty trucks, there will be no shaft. The axle in this condition works just as a steering component and as suspension. Numerous front wheel drive cars consist of a solid rear beam axle.
The axle serves just to transmit driving torque to the wheels in several kinds of suspension systems. The position and angle 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 several new cars and light trucks. These systems still consist of a differential but it does not have connected axle housing tubes. It can be connected to the vehicle body or frame or even 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 vehicle axle has a more vague definition, meaning that the parallel wheels on opposing sides of the vehicle, regardless of their type of mechanical connection to one another.
