Lamella switching element arrangement for automated transmission in planetary structure, has lamella package axially movable by piston and including friction lamella that is sparingly formed so that resetting force is applied on piston

摘要

The arrangement has a lamella clutch and/or a lamella brake (2) including two lamella packages (3, 4). One of the packages is axially movable by a piston (7) so that torque transmission between friction lamellas (5, 8) of the two corresponding lamella packages is allowed. One of the friction lamellas is formed sparingly so that resetting force is applied on the piston, and is bent in an area of attachment. Radially outer ends (12) of the friction lamellas of the axially movable lamella package are bent into axial direction.
