ABSTRACT:
A dual wheel and axle assembly having a wedge lock hub and axle assembly with an auxiliary clamp to augment the grip of the hub on the drive axle. A drive is provided to force bushing segments between the wheel hub and the drive axle to firmly lock the wheel hub and axle together. One of the bushing segments has an extension which extends axially along the drive shaft and carries a clamp in the form of at least one U-bolt having curvature mating that of the peripheral surface of the drive axle. The U-bolt is firmly clamped against a portion of the drive axle while the extension of the bushing segment which has an integral key firmly seats in a key slot of the drive axle to augment the grip of the wheel hub on the drive axle to accommodate additional torque produced by adding dual wheels to a conventional single wheel drive on the tractor.
