Embodiment Construction
[0031] observing figure 1 A first embodiment of the operating device 1 according to the invention can be seen when the drive unit 30 is shown. In this illustration, the operating device 1 has been installed in the drive unit 30 and is operatively connected to the clutches 5 , 6 of the clutch system 2 of the drive unit 30 . The actuating device 1 is mounted in an interior space 22 of a clutch housing 23 of the clutch system 2 . In addition to the clutch system 2 , which is designed here as a hybrid module, the drive unit 30 also has a transmission device 26 , only the transmission input shafts 27 a and 27 b of which are shown for the sake of clarity. In operation, the drive unit 30 is a component of the hybrid vehicle powertrain (hybrid powertrain).
[0032] About the clutch system 2, you can find figure 1 It can be seen in detail in that the clutch system 2 has a total of three clutches 5 , 6 , 33 . The three clutches 5 , 6 , 33 are also referred to as triple clutches. Th...

Abstract
The invention relates to an actuation device (1) for a clutch system (2) of a motor vehicle, having: two slave cylinders (3, 4) which are each designed to actuate a clutch (5, 6), each slave cylinder(3, 4) having a piston (7a, 7b) and a housing component (9a, 9b) which guides the piston (7a, 7b) in its displacement direction and, together with the piston (7a, 7b), delimits a fluid chamber (8a, 8b); and having a supply component (10), the slave cylinders (3, 4) being provided on the supply component (10) in such a way that, per slave cylinder (3, 4), a fluid supply channel (11a, 11b) of the supply component (10) is fluidically connected to the fluid chamber (8a, 8b), wherein the housing components (9a, 9b) of the two slave cylinders (3, 4) are supported directly on each other or on the supply component (10) in an axial direction of a longitudinal axis (12) of the supply component (10). The invention also relates to a clutch system (2) for a drive train of a motor vehicle, the clutch system having this actuation device (1); and to a drive unit (30).
Description
technical field [0001] The invention relates to an operating device suitable for a clutch system of a motor vehicle, such as a passenger car, truck, bus or other commercial vehicle, said operating device having two slave cylinders (first slave slave cylinder and a second slave cylinder), wherein each slave cylinder has a piston and a housing member that guides the piston in the direction of movement of the piston and defines a fluid chamber with the piston, and with a supply member on which the slave cylinders are arranged in such a way that for each slave cylinder the fluid delivery channel of the supply member is connected to (of the slave cylinder) The fluid chambers are fluidically connected. This results in an actuating device with double slave cylinders. Furthermore, the invention also relates to a clutch system suitable for a motor vehicle powertrain with two clutches and the actuating device. Furthermore, the invention relates to a drive unit suitable for use in a m...
