Embodiment Construction

[0040] figure 1 An actuating unit 1 is shown which has an electric motor 2 as drive unit, a transmission unit 3 , a spring compensation unit 4 and a pushrod 5 as actuating element.

[0041] The transfer unit 3 comprises a preload spring 6 , a stop spring 7 , a gear sector 8 , a driver 9 as connecting element and a coil spring 10 . The compensating spring unit 4 has an spherical plain bearing 12 , a spring guide 14 and a compensating spring 16 .

[0042] Furthermore, the actuating unit 1 has a housing 18 for accommodating components of the transmission unit 3 and of the compensation spring unit 4 as well as the plunger 5 ; the housing 18 is closed with a cover 20 . The operating principle of the actuating unit 1 for the engaged clutch is described below. However, by modification, the actuation unit 1 can also be used for an open clutch. In this case, this modification concerns the actuation of the electric motor 2 and the design of the push rod 5 . This modification is know...

Abstract

The invention relates to an actuating unit for a clutch comprising a drive unit, an actuating element for actuating the clutch and a transmission unit for transmitting a torque generated by the drive unit to the actuating element, wherein , the transfer unit includes a wear compensation mechanism, through which the engagement position of the operating element can be matched to the wear state of the clutch, characterized in that the lever arm between the transfer unit and the operating element follows increases with the change in engagement position due to wear compensation matching.

Description

technical field [0001] The invention relates to an actuating unit for a clutch comprising a drive unit, an actuating element for actuating the clutch and a transmission unit for transmitting a torque generated by the drive unit to the actuating element, wherein the transmission unit comprises a wear compensation mechanism by which the engaged position of the actuating element can be adapted to the wear state of the clutch. Background technique [0002] An actuating unit for clutches is known from DE 100 59 374 A1, in which a motor drives a screw tooth, by means of which a gear sector is driven. A joint receptacle is provided on the gear sector for receiving a joint head of a push rod with which the clutch can be disengaged. Furthermore, the actuation unit includes a compensating spring for reducing the required separation force. [0003] It is also known that actuating units of this type are provided with wear compensation. That is, in the clutch disc, wear occurs with co...
