A belt or chain bearing surface of the flexible member bears upon a belt or chain trained between two pulleys. The flexible member is compressible in response to a preload caused as the idler is pressed against the chain or belt. The flexible member damps vibrations in the belt or chain during operation. This results in quieter operation of the idler/pulley system as well as increases the operating life of the belt.Type: GrantFiled: March 28, 2001Date of Patent: April 1, 2003Assignee: The Gates CorporationInventor: John D.

Patent number: 6540631Abstract: An improved electrically variable transmission, especially useful in a hybrid electric vehicle, includes a variable input power split and independent shifting of the gear ratios of the mechanical and electrical power paths through the transmission. A first electric machine varies the ratio of the mechanical power path, and a second electric machine defining the electrical power path is mechanically connected to the output at two or more ratios and electrically connected to the first electric machine and optionally to an electric storage device. The mechanical connection of the second electric machine can be reconfigured without disturbing the output whenever the power flow through the electrical power path is zero. The second electric machine and electric storage device can sustain the output when the mechanical power path is reconfigured.Type: GrantFiled: August 13, 2001Date of Patent: April 1, 2003Assignee: General Motors CorporationInventor: Alan G. Holmes

Patent number: 6540632Abstract: A wheel drive preferably used in a low-platform bus for driving the wheels is driven by a drive motor (1) eccentrically arranged relative to the wheel axle (12) and a gearwheel (2). The driven gearwheel (2) of a reduction gear (3) is in intermeshing connection with two additional gearwheels (6) and one outer central wheel (5) in a manner such that the drive torque is distributed onto the gearwheels (6) and the outer central wheel (5) and the driven gearwheel (2) can be floatingly supported so that a uniform load distribution results.Type: GrantFiled: December 13, 2001Date of Patent: April 1, 2003Assignee: ZF Friedrichshafen AGInventors: Harald Wendl, Max Bachmann

Patent number: 6540633Abstract: A transmission for speed changing and steering of a vehicle includes a first hydrostatic pump (52) and motor (53), a first differential (24′) for speed changing, a second hydrostatic pump (71) and motor (72), and a second differential (23′) for steering. A prime mover drives the first pump (52), and the second pump (71) is driven by the output from the first motor (53). The second motor (72) drives the second differential (23′) for steering the vehicle.Type: GrantFiled: November 21, 2000Date of Patent: April 1, 2003Assignee: Tuff Torq CorporationInventors: Toshiyuki Hasegawa, Travis S. McCloud, Keith J Andrews, Robert Abend

Patent number: 6540634Abstract: A wheel differential having an improved differential lock assembly is provided. The differential includes a differential housing and a differential cage rotatably supported on the differential housing by a set of bearings. The differential also includes a clutch assembly having a first member fixed to the differential cage and a second member configured to receive an axle half shaft extending from the differential cage for rotation with the axle half shaft. Finally, the differential includes an improved differential lock assembly that selectively shifts the first and second clutch members into engagement to prevent relative rotation between the differential cage and axle half shaft. The lock assembly includes a shift chamber that is supported on an outer race member of the set of bearings. The shift chamber may be formed within a bearing cap that is coupled to the differential housing and disposed about at least a portion of the bearing set.Type: GrantFiled: December 4, 2000Date of Patent: April 1, 2003Assignee: Dana CorporationInventor: David Thompson

Patent number: 6540635Abstract: An automatic transmission has a frictionally engaging element, such as a low-and-reverse brake or the like, that is hydraulically actuated for assuming a certain gear position. A hydraulic control system for the transmission comprises a first hydraulic section which produces a line pressure; a solenoid which produces a solenoid pressure; a decompression control valve which receives the line pressure to produce an output pressure while using both the solenoid pressure and the output pressure as signal pressures; a switching valve interposed between the decompression control valve and the frictionally engaging element. The switching valve has a first position wherein the output pressure is fed to the frictionally engaging element and a second position wherein the line pressure is fed to the frictionally engaging element.Type: GrantFiled: June 12, 2000Date of Patent: April 1, 2003Assignee: Jatco LTDInventor: Takashi Sano
