Problems solved by technology

The disadvantage here is that, although it is possible to compensate for clutch wear due to the tank line connecting the active oil chamber to the reservoir via a proportional valve, the lack of its own compensating reservoir to operate the bleed is possible at any time in a limited manner

Embodiment Construction

[0024] In order to operate the clutch, the clutch control device 1 mainly includes a control unit 2 , a hydraulic control device 3 , a controller 4 and a slave cylinder 5 .

[0025] The control unit 2 includes a master cylinder 6 whose inner cavity is divided into a slave oil chamber 8 and a master oil chamber 9 by a longitudinally displaceable master piston. Arranged in the master oil chamber 9 is a compression spring 10 which, in the depressurized state, presses the master piston 7 into its initial position in the slave oil chamber 8 . In the initial position of the active piston 7 , the active oil chamber is connected to the compensation container 12 via the compensation line 11 . The active piston 7 has ring grooves (Ringnut) 13, 14 towards the driven oil chamber 8 and towards the active oil chamber 9, respectively, in which a seal 15, 16 is respectively arranged for sealing with respect to the adjacent pistons. The cylinder inner wall 17 creates a seal. In addition to t...

Abstract

An actuation device and a method for actuating a clutch, in particular for a hybrid drive, include a master cylinder having an interior separated by a master piston into master and slave oil chambers. The slave oil chamber is connected, via a valve in a first valve position, to a tank line leading to an oil reservoir and in a second valve position, to a pressure line of the oil reservoir. The master oil chamber is connected via a working line to an oil chamber of a slave cylinder and to a compensating tank via a compensating line as a function of the position of the master piston. The compensating tank has a compensating volume which has, at its highest point, an overflow which is connected to the tank line and in its first position the valve connects the slave oil chamber to the compensating tank via a return line.

Description

technical field [0001] The invention relates to an actuating device (Ansteuerung) in particular for a clutch (Kupplung) of a hybrid drive, the actuating device having a master cylinder (Geberzylinder), the inner chamber of which is divided into a slave oil chamber by a master piston (Geberkolben) and active oil chamber In this case, the output oil chamber is connected via a valve in the first valve position to the tank line leading to the oil reservoir and in the second valve position to the pressure line of the oil reservoir, and wherein The master oil chamber is connected via a working line to the oil chamber of the slave cylinder (Nehmerzylinder) and, depending on the position of the master piston, to a compensating container via a compensating line. [0002] The invention also relates to a method for actuating a clutch, in particular for a hybrid drive, in which method, in order to actuate a working piston in a slave cylinder associated with the clutch, through a valve ...
