ABSTRACT:
An improved axle for a vehicle maintains the wheels of the vehicle in a upright position when the wheels pass over irregularities in the surface of a road and holds the body of the vehicle in a fixed position with respect to the wheels when a lateral force such as a centrifugal force is applied to the body. The axle includes a shaft which supports the wheels of the vehicle and which pivots when the wheels roll over irregularities in the surface of a road. The shaft has two offset end portions which each support a wheel. The end portions are connected by a central bar which is pivotally and slidably supported so that the end portions move in arcuate paths when the shaft pivots. A wheel support assembly is provided for each end portion of the shaft to connect a wheel to the end portion and to change the arcuate movement of the end portion to a corresponding vertical movement of the wheel, so that the wheel is deflected in a vertical plane when it rolls over an irregularity of the surface. The wheel support assemblies also retain the shaft against lateral movement with respect to the body.
