Coupling system for coupling double clutch gearbox with friction clutches in car, has elastic unit envisaged between two operation points in case of friction linings in specific state

摘要

The system (1) has friction clutches (2, 3) equipped with backpressure plates (5, 6) and toggle plates. An actuation trajectory is fixed between an opening position and an operation point in a case of friction linings (12, 13) worn until a limit of pre-defined wear. Elastic units (24, 25) limit the force between an actuator of a clutch and the toggle plates that are provided on a partial trajectory of the actuation trajectory. The elastic unit is envisaged between the operation point and another operation point in the case of friction linings in a specific state.
