摘要： A multiple plate friction clutch includes clutch plates or discs having reduced frictional (spin) losses and thus reduced heat generation and improved service life. The clutch plates include both leaf springs or spring tabs at the periphery of the clutch plate that axially bias adjacent plates away from one another and a reduced area of friction material that contacts an adjacent reaction plate. On a typical motor vehicle automatic transmission clutch, a total of six or eight leaf springs or tabs are utilized: with three or four offset to one side and three or four offset to the other side.

摘要： A method of cooling a dual clutch transmission is provided. The transmission has first and second input clutches alternately engagable to transfer torque to an output member along first and second input shafts, respectively, at various speed ratios dependent upon engagement of synchronizers. The method includes determining a currently established speed ratio by determining which of the input clutches and synchronizers are currently engaged and which of the input clutches and synchronizers are currently open. One of the open synchronizers is then engaged during the currently established speed ratio to cause the open input clutch to rotate at a speed greater than the speed of rotation of the engaged input clutch, thereby creating a fan cooling effect.

摘要： A transmission and a clutch assembly for a vehicle are disclosed. The clutch assembly includes a housing defining a cavity presenting an interior surface. The interior surface defines a pocket along a longitudinal axis. The clutch assembly further includes a piston disposed in the pocket and movable between an initial position and a final position relative to the pocket along the longitudinal axis. The piston includes a plurality of flanges extending outwardly away from the longitudinal axis. The clutch assembly also includes a biasing member attached to the interior surface of the housing and engaging the piston to continuously bias the piston toward the initial position. The biasing member abuts the flanges of the piston to prevent rotation of the piston about the longitudinal axis as the piston moves between the initial and final positions along the longitudinal axis.

摘要： A clutch assembly for transmitting a first torque between a first member and a second member includes a first clutch and a second clutch. The first clutch is disposed between the first member and the second member and has a predetermined design torque. The second clutch is disposed in series with the first clutch between the first member and the second member and has a predetermined holding torque that is less than the predetermined design torque. The second clutch allows rotation between the first member and the second member when the first torque is greater than the predetermined holding torque.
