摘要： A friction member has a pair of friction facings 46a and 46b that are designed to reduce drag torque during operation in a fluid filled chamber. The friction member has a circular friction plate 43 with an aperture at its center and the friction facings 46a and 46b are coupled thereto. The friction member can be part of a lock-up device 4 of a torque converter 1 or a part of a power cut-off clutch 102 of a torque converter. The friction member has a first friction facing 46a that is formed of an annular and flat main body. The main body has a first surface fixedly coupled to the friction plate 43 and a second surface on the opposite side with a plurality of grooves 81. The grooves 81 extend through from the inner periphery to the outer periphery and having bent portions 83 and 85 at a middle area. In another embodiment, a friction member is provided with friction facings 141 and 142 with center apertures, which are rotatable in a fluid chamber around a central axis to suppress lowering of fluid pressure due to rotation. The annular friction surfaces of the facings 141 and 142 are provided with a plurality of grooves 190. Each of the grooves 190 extends from the inner periphery to the outer periphery and has a bent portion at a middle area. The bent portion of the groove 190 is formed of radially outer and inner grooves and has a V-shaped opening in the rotating direction of the friction facings. The bent portion prohibits the rapid flow of fluid through the groove. Consequently, lowering of the fluid pressure can be suppressed.

摘要： A method of controlling the pressure applied to the engaged clutch of a vehicle having a dual clutch transmission to control the torque transferred across the engaged clutch thereby providing engine speed control for each gear based on the engine throttle position. The method includes the steps of determining the engine throttle position, determining the currently engaged gear of the transmission, and sensing the speed of the clutch. An engine stall speed is selected for the current gear and engine throttle position from a look-up table, and then a target engine speed based on the engine stall speed and the clutch speed is continuously redetermined, the clutch speed increasing in response to the increasing engine speed. The method also includes determining the difference between the target engine speed and the actual engine speed and then varying the torque transferred across the clutch driving the engaged gear to cause the engine to track the target engine speed based on the difference between the target engine speed and the actual engine speed.

摘要： The pressure plate has at least one friction surface region which can be pressed against a friction facing arrangement of a clutch disk or the like, wherein the pressure plate is formed at least partially from a first material, and wherein a second material having thermal contact with the first material is provided in the pressure plate at least in some areas. In order to be able to compensate for negative umbrella deformation of the pressure plate caused by friction heat during operation of the clutch, the second material has a different thermal expansion, particularly a greater thermal expansion, than the first material.
