Patent number: 8297385Abstract: A dual wheelend for an axle assembly having a rotatable axle shaft. The wheelend comprises a spindle defining a first axis. An intermediate hub is supported on the spindle for rotation about the first axis during rotation of the axle shaft. An inner wheel hub and an outer wheel hub are adjacent one another and are each supported on the intermediate hub for rotation about the first axis. A differential mechanism interconnects the inner and outer wheel hubs. A pin is disposed through a pinion along a second axis and couples the differential mechanism to the intermediate hub for driving the wheel hubs during rotation of the intermediate hub and permitting relative rotation between the wheel hubs relative to the intermediate hub. The pin includes proximal end with a head disposed on the proximal end for engaging the pinion and sandwiching the pinion between the head and the intermediate hub.Type: GrantFiled: April 10, 2012Date of Patent: October 30, 2012Assignee: Axletech International IP Holding, LLCInventors: Daniel Chien, Alexandru Florea, Tim G. Langlitz, Ken L. Phillipi, Craig R. Roble

Patent number: 8151913Abstract: An axle assembly for a vehicle comprising a stationary spindle and a rotatable axle shaft. An intermediate hub is supported on the spindle. Adjacent inner and outer wheel hubs are supported on the intermediate hub. A differential mechanism interconnects the inner and outer wheel hubs for driving both of the wheel hubs and for permitting relative rotation between the wheel hubs. At least one differential bushing is disposed between the differential mechanism and the intermediate hub. A gear reduction system interconnects the intermediate hub and the axle shaft for providing torque multiplication. A wet disc brake device is coupled between the spindle and the intermediate hub.Type: GrantFiled: June 18, 2010Date of Patent: April 10, 2012Assignee: Axletech International IP Holding, LLCInventors: Daniel Chien, Alexandru Florea, Tim G.
