Abstract

The invention discloses an actuator (1) that can be used as a clutch actuator/starter, as a clutch actuator/generator, or as a clutch actuator/starter/generator. Consequently, an actuator that is embodied as an auxiliary unit can perform several functions for the motor (12), thus permitting the number of parts, the amount of space required, and the weight of the motor to be reduced.

Claims

1. An actuator for actuating a clutch (7, 8), which brings the clutch (7, 8) into and out of engagement by means of a gear train (4, 5), characterized in that the actuator (1) can simultaneously also be used as a starter for a motor (12).

2. The actuator according to claim 1, characterized in that the actuator (1) can also be used as a generator.

4. The actuator according to one of claims 1 to 3, characterized in that a bypass clutch (15) is provided in order to bypass the clutch (7, 8).

5. The actuator according to one of claims 1 to 4, characterized in that the gear train has a gear (5) with a helical gearing, which when driven by the actuator (1), brings the clutch (7, 8) into or out of engagement.

6. The actuator according to one of claims 1 to 5, characterized in that the actuator (1) permits a recovery of braking energy and/or a synchronization of the controllable clutches during gear changes.

7. The actuator according to one of claims 1 to 6, characterized in that when being used as a starter, the actuator brings the motor (12) into engagement with an outer disk support (8) by means of a gear train (4, 5) and an inner disk support (7), wherein the outer disk support (8) is connected to the motor (12) by means of a hollow shaft (9) and a transmission (11), thus permitting the motor (12) to be started.

8. The actuator according to one of claims 1 to 7, characterized in that when being used as a starter, the actuator can start the motor (12) by means of a gear train (4, 5), an inner disk support (7), and a shaft (10) that is connected to the motor (12).

9. The actuator according to one of claims 1 to 8, characterized in that the gear train (4, 5) is locked together by means of a thrust collar (6) when the disk clutch is disengaged.

10. A use of an actuator according to one of the preceding claims in a double-clutch gear train.

3. An actuator for actuating a clutch (7, 8), which brings the clutch (7, 8) into and out of engagement by means of a gear train (4, 5), characterized in that the actuator (1) can simultaneously also be used as a generator.
