A novel automatic transmission with latching multi-plate clutches

摘要

A linear actuator, suitable for a clutch ( 5, 6 ) of a motor vehicle transmission, has a bi-stable latch mechanism ( 18, 20 ) adapted to maintain an actuating member ( 26 ) in one of two positions on the output axis. Repeated applications of fluid pressure cause the actuator to alternate between the bi-stable states, and may thus cause a clutch to alternate between engaged and disengaged conditions.
