The drive member is secured to the wheel hub which is rotated thereby about the axle tube.

Abstract: An adjustable wheel assembly which facilitates the positioning of a wheel on an axle. The wheel assembly includes an elongated axle having a rack and a keyway, a wheel hub, and two pairs of arc-shaped wedges positioned between the axle and the wheel hub. Two of the four arc-shaped wedges are inserted into a tapered bore on one side of the wheel hub and the remaining two wedges are inserted into a second tapered bore on the opposite side of the wheel hub. Each of the four arc-shaped wedges further contains a radial flange with bolt holes therethrough so that each wedge can be bolted to the wheel hub. In addition, one of the wedges contains a radial opening housing pinion gear which meshes with the rack on the axle so as to axially move the wheel hub along the axle. The wheel assembly also contains a pair of jackscrews which are used to force two of the oppositely aligned wedges axially apart thereby allowing the wheel hub to be released from the axle.

Abstract: A remotely controlled manual hub clutch assembly includes an axle and a wheel hub rotatably mounted on a vehicle housing. A pair of relatively movable coupling portions provide an engageable and disengageable driving connection between the axle and the wheel hub. The vehicle operator may engage and disengage the coupling members by moving a linkage connected to a movable one of the coupling members. A synchronizer prevents engagement of the coupling members until the rotation speeds of the wheel hub and the axle are substantially equalized so that the hub clutch can be engaged or disengaged while the vehicle is in motion. A non-rotating sleeve surrounds the axle and acts as a linkage to operate the coupling members.

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.

The web of each wheel between the hub and the rim is provided with apertures complementarily formed relative to the axles for receiving the axle or axles of another wheel or wheels therethrough to permit nesting the wheel structures.

Abstract: A clamp style wheel bushing on a drive wheel of a tractor for clamping the drive axle to the drive wheel. The wheel hub and cap are cast with internal shaft bearing surfaces on the cap and hub to firmly clamp the drive axle and lock the drive wheel to the drive axle.

Abstract: A wheel of the welded spoke variety has a hub with specially designed end caps. If the wheel is to be used as a front wheel of a tricycle, a pedal crank shaft having radial tabs is slid through openings in the end caps having inwardly projecting lips. As the shaft is forced further through the hub, the tabs slice into the rim around the opening in the distal end cap and also upset portions of the rim ahead of the cut into shaft slots just ahead of the tabs. This locks the hub to the shaft both axially and rotationally. If the wheel is to be used on a sidewalk bike with a coaster brake installed in the hub instead of a pedal crank, a circular array of teeth are formed in the outer surface of the proximate end cap which interfit with teeth on an element of the brake so that the brake element and hub rotate together.

First and second wheels are provided for mounting, respectively, on the first and second axle ends. The first wheel is rigidly connected to the first axle end for rotation with the axle such as by pinning or by a key. A torque-limited driving connection is provided between the second wheel and the second axle end, the torque-limited driving connection permitting relative rotation between the second wheel and axle when a predetermined torque level is exceeded. This torque-limited device may include a frictional drive connection between the second wheel and the axle.

Abstract: An improved wheel assembly includes a pair of contact bearings which are displaced from the vertical center line of the wheel for reducing frictional forces and the required torque in rotating the wheel. The bearings contact the inner surface of a drum having a pair of side plates, one of which has a central aperture. A weight bearing sleeve is located through the aperture and includes sleeve extension arms which are affixed to the contact bearings. A rotatable axle is located within the sleeve and extends through the drum so that the axle may be affixed to the other side plate of the drum. The drum thus rotates with the axle, and the vehicle weight is transferred from the sleeve to the drum by the two contact bearings which rotate in place.
