Embodiment Construction

[0031] observing figure 1 A preferred 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 , here designed as a hybrid module, the drive unit 30 also has a transmission device 26 , of which only the transmission input shafts 27 a and 27 b and the transmission housing 15 are shown for the sake of clarity. a part of. 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 a...

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 region (9a, 9b) which guides the piston (7a, 7b) in a displacement direction and, together with the piston (7a, 7b), delimits a fluid chamber (8a, 8b); and having a supply unit (10), the slave cylinders (3, 4) being provided on the supply unit (10) in such a way that, per slave cylinder (3, 4), a fluid supply channel (11a, 11b) formed by the supply unit (10) is fluidically connected to the fluid chamber (8a, 8b), wherein the housing regions (9a, 9b) of the two slave cylinders (3, 4) are formed directly by the supply unit (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 master cylinder and second slave cylinder), wherein each slave cylinder has a piston and a housing area that guides the piston in its direction of movement and defines a fluid chamber with the piston, and With a supply unit, the slave cylinders are arranged on the supply unit in such a way that for each slave cylinder, the fluid delivery channel formed by the supply unit is connected to the (slave The fluid chambers of the cylinder are connected by fluid technology. 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 u...
