Patent number: 10962116Abstract: A rotary seal comprises a seal element comprising a disc-shaped body having a first axial side and an opposed second axial side. The seal element further comprises a radially inner central circular opening for receiving a rotary shaft, the opening having an inner periphery for sealing engagement with the shaft. A radially outer rim portion of the seal element comprises an axially facing annular sealing surface provided on the first axial side for sealing engagement in use with an opposed axially facing sealing surface of an adjacent first static housing and an axially facing pocket provided on the second axial side and having an axially facing surface for receiving, in use, an annular elastomeric biasing element.

Patent number: 7380890Abstract: A system is provided for controlling automatic brake systems to avoid pulsing vehicle brakes at certain natural vibration frequencies of the vehicle's mechanical systems such as a powertrain and driveline. The natural vibration frequencies of the vehicle's systems are determined and correlated with a range of possible braking regimes implemented by an on-board automatic brake control, such as an anti-lock braking (ABS) system. A proposed, normally appropriate ABS braking response to a sudden braking condition is either modified, accelerated or delayed when the proposed response is deemed likely to excite a vehicle natural frequency. The system improves ABS operation in vehicles having high effective inertia powertrains, such as those used in hybrid electric vehicles.Type: GrantFiled: February 17, 2004Date of Patent: June 3, 2008Assignee: Ford Global Technologies LLCInventors: Bill Tobler, Michael Tiller, Paul Bowles

Patent number: 7349788Abstract: A system is provided for controlling the inertia of a vehicle's powertrain during sudden braking events. Torque generated by rapid deceleration of the vehicle's drive wheels during braking is prevented from being transmitted through the vehicle's driveline by a clutch which disengages the drive wheels from high effective inertia components in the driveline. The clutch is actuated by a signal produced by any of several sensors on the vehicle which sense a sudden braking event. Driveline speed is adjusted to match drive wheel speed before the clutch is deactivated to reengage driveline with the drive wheels.Type: GrantFiled: November 25, 2006Date of Patent: March 25, 2008Assignee: Ford Global Technologies LLCInventors: Bill Tohler, Michael Tiller, Paul Bowles

Patent number: 7197383Abstract: A control system limits reactive torque in a powertrain that is generated when braking force is applied to traction wheels during a sudden stop or other sudden braking event. The reactive torque generated at the traction wheels is prevented from being transmitted upstream through the driveline and powertrain by using a slip type clutch in the driveline to limit the upstream transfer of the reactive wheel torque. The clutch is directly actuated by the reactive torque and therefore does not require special controls or monitoring systems to sense the braking event. The clutch pressure may be automatically adjusted in response to certain operating conditions or events, thereby adjusting the point at which the clutch begins to slip due to reactive wheel torque.Type: GrantFiled: February 17, 2004Date of Patent: March 27, 2007Assignee: Ford Global Technologies, LLCInventors: Bill Tobler, Michael Tiller, Paul Bowles
