Hydrokinetic torque converter with lock-up clutch and internal vibration damping.

摘要

A hydrokinetic unit (10) for use with an automatic power transmission mechanism in an automotive vehicle driveline comprising a lock-up clutch (88, 90, 92) for connecting directly the turbine (30) and the impeller (12) of the hydrokinetic unit to effect a fully mechanical, direct drive therethrough, the lock-up clutch being situated internally of the hydrokinetic unit and including a vibration cushion and damper (106) that cushions clutch engagement and eliminates or reduces undesirable torque variations or pulses in the driveline when the clutch is engaged and during clutch engagement thereby improving the driveability of the vehicle.
