Patent number: 8662277Abstract: A brake mechanism includes a fixed housing in which the brake mechanism substantially resides. A plate closes the fixed housing and includes a cylindrical portion extending partially within the fixed housing. A parking piston and a service piston are employed to act against a brake stack which includes a plurality of stators and rotors interleaved together. A wear adjuster is press-fit onto the cylindrical portion of the plate and engages the service piston during actuation of the service piston and compensates for wear of friction material from the rotors or stators such that the distance between the service piston and the brake stack is substantially the same during the life of the brake mechanism. If neither the service piston nor the parking piston engage the brake stack prohibiting rotation of the input drive, the planetary gear set drives the rotating output drive with respect to the fixed housing.Type: GrantFiled: December 22, 2011Date of Patent: March 4, 2014Assignee: Fairfield Manufacturing Company, Inc.Inventor: Benjamin Warren Schoon

Patent number: 8340880Abstract: A system and method for controlling torque and/or speed of wheels of a vehicle. The system and method receive one or more vehicle operating signals. Based on the received vehicle operating signals, the system and method determine whether one or more of a vehicle's wheels require torque or speed modification. If it is determined that one or more of the vehicle's wheels requires torque or speed modification, the system and method modifies the torque to drive, or speed of, a wheel or wheels based on the received vehicle operating signals. The modification is automatic and/or independent for each wheel. Some or all wheels can be coupled to respective wheel hubs having incorporated therewith an engagement/disengagement mechanism. The system and method can control the engagement/disengagement mechanism to modify the torque at, or speed of, the associated wheel based on the received vehicle operating signal or signals.Type: GrantFiled: August 27, 2008Date of Patent: December 25, 2012Assignee: Lockheed Martin CorporationInventors: William C. Craig, Richard S. Stevens

Patent number: 7044883Abstract: The invention relates to a device for driving a wheel of a vehicle. The device includes a hub for carrying the wheel in a rotationally fixed manner, a planetary gear connected between a driving axle and the hub, which planetary gear includes a planet carrier which is connected in a rotationally fixed manner to the hub, and an arrangement for fixing the hub and the planet carrier in the intended position relative to one another in the axial direction. Both the hub and the planet carrier include a hole which extends in the axial direction. At least one of the holes forms at least a part of a continuous opening through the hub and the planet carrier in the axial direction. The fixing arrangement comprises an elongate element arranged in the continuous opening and an arrangement for fixing the hub and the planet carrier relative to one another in the axial direction via the elongate element.Type: GrantFiled: September 5, 2005Date of Patent: May 16, 2006Assignee: Volvo Construction Equipment Holding Sweden ABInventors: Thomas Andersson, Lars Larsson, Mats Akerblom

Patent number: 6904987Abstract: An electric drive for an electric or hybrid vehicle has an electric motor, with which a vehicle wheel is drivable, for instance via an articulated shaft. The the electric drive is embodied additionally with a mechanically actuatable wheel brake, which is actuatable by the electric motor selectively for driving the vehicle wheel via a shiftable distributor gear. The invention has the advantage that the electric motor provided for driving the vehicle wheel is simultaneously used for actuating the wheel brake (24) as well.Type: GrantFiled: December 14, 2000Date of Patent: June 14, 2005Assignee: Robert Bosch GmbHInventors: Hardy Haas, Ian Faye, Herbert Vollert
