Patent number: 5695022Abstract: A power transfer system for a four-wheel drive vehicle is disclosed having a transfer case with its input angled relative to its outputs by means of a constant velocity (CV) universal joint. More specifically, the transfer case input includes a first rotary member adapted to be rotatably driven about the rotary axis of the transmission output shaft, a second rotary member supported for rotation about a second rotary axis that is angled relative to the first rotary axis, and a CV joint interconnecting the first and second rotary members. The transfer case outputs include a pair of rotary output members supported for relative rotation about a common third rotary axis that is offset from the second rotary axis. A torque transfer arrangement is provided for transferring torque from the transfer case input to its outputs. As such, the CV joint allows the transfer case to be angulated so that reduced departure angles are achieved with respect to the prop shaft connections.Type: GrantFiled: November 27, 1995Date of Patent: December 9, 1997Assignee: New Venture Gear, Inc.Inventors: John D.

Patent number: 5695028Abstract: A torque converter is provided with both a lock-up clutch and a disengaging clutch for use with a manual transmission. When the disengaging clutch is engaged, torque is transmittable through a torque converter impeller and turbine fluid coupling. When the lock-up clutch is engaged, torque is mechanically transmitted through the lock-up clutch to a manual transmission input shaft. A single control mechanism effects selective engagement and disengagement of both the lock-up clutch and the disengaging clutch. In an alternate embodiment of the present invention, a weight may be engaged and disengaged from various components within the torque converter to change the ratio of a moment of inertia of a power input mechanism and a power output mechanism defined by portions of the torque converter. A lock-up clutch in the alternate embodiment and the weight are also engaged and disengaged by a single control mechanism.Type: GrantFiled: February 16, 1996Date of Patent: December 9, 1997Assignee: Exedy CorporationInventor: Hirotaka Fukushima
