摘要： A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch module. Dual clutch actuation device includes a first and second annular piston. The annular pistons are arranged in concentric annular piston slots. Together the piston and annular slots form annular piston chambers. The actuation device further includes a first set of wiper seals and a second set of wiper seals disposed in a first and a second annular channel in each of the annular pistons. Advantageously, contamination of the piston chambers is reduced or eliminated through the wiping or cleansing action of the first and second set of wiper seals against walls of the annular slots formed in the housing of the actuation device.

摘要： A dual clutch actuation device generates the axial compression force required to compress a first and second set of frictional elements of a dual clutch module. Dual clutch actuation device includes a first and second annular piston. The annular pistons include a first end that is in contact with annular bearing assemblies. The annular bearing assemblies are in contact with actuation levers that are in contact with the first set of frictional elements. The annular pistons are arranged in concentric annular piston slots. Together the piston and annular slots form annular piston chambers. The piston chambers are filled with hydraulic fluid. The actuation device further includes a first set of wiper seals and a second set of wiper seals disposed in a first and a second annular channel in each of the annular pistons. When the hydraulic fluid is pressurized the pistons slide out of the annular slots and apply a force on the actuation levers which in turn apply an axial compression force on the frictional elements. Advantageously, contamination of the piston chambers is reduced or eliminated through the wiping or cleansing action of the first and second set of wiper seals against walls of the annular slots formed in the housing of the actuation device.

摘要： A transmission having a sealing baffle is disclosed. The transmission further includes a transmission case, a torque converter housing and a torque transfer member. The transmission case has a drive sprocket and a driven sprocket mounted for rotation therein. The torque converter housing has a fluid pump for pumping lubrication fluid. The torque converter housing is configured to mount to the transmission case. The torque transfer member is coupled to the drive sprocket and to the driven sprocket for transferring a driving torque from the drive sprocket to the driven sprocket. The first baffle is mounted to the torque converter housing. The first baffle has a base, a first flange extending from a first side of the base, a second flange extending from a second side of the base and a sealing lip formed in the second flange. The sealing lip contacts the transmission case to form a seal to prevent the fluid from flooding the torque transfer member. The seal created by compression of the sealing lip against the transmission case and the subsequent thermal expansion of the baffle and sealing lip is maintained over the entire operating temperature range of the transmission.

摘要： A seal protector assembly is provided. The seal protector assembly includes a cavity for encasing a seal. A plug or cap is removably attached to the protector seal. After shipment of the transmission, the plug or cap is removed. Once any potential damage to the seal during assembly has passed, the protector is then removed.
