Dual wheel assembly differential

A dual wheel assembly (10) is provided that includes a spindle (12) having an axle shaft defining a rotational axis. The axle shaft has a drive pinion (15). A first wheel hub (16) is supported on the spindle and is positioned to be rotatably driven about the rotational axis. A second wheel hub (18)...

Zusammenfassung:	A dual wheel assembly (10) is provided that includes a spindle (12) having an axle shaft defining a rotational axis. The axle shaft has a drive pinion (15). A first wheel hub (16) is supported on the spindle and is positioned to be rotatably driven about the rotational axis. A second wheel hub (18) is arranged adjacent to the first wheel hub and is also rotatable about the rotational axis. The second wheel hub (18) may be supported by the first wheel hub (16) or the spindle (12). A differential assembly is interconnected between the first wheel hub and the second wheel hub. The differential assembly permits both wheels to be driven for increase traction while allowing the second wheel hub to rotate relative to the first wheel hub. A gear reduction assembly (20) interconnects the differential assembly and the drive pinion to provide torque multiplication to the wheel hubs. In this manner, the gear reduction assembly provides the additional torque required for heavy vehicles while the differential assembly allows relative rotation of the wheel hubs.
