Example Embodiment

[0060] in figure 1 The drive train for a motor vehicle is shown in schematic form in and is generally designated 10. The drive train 10 has a drive motor 12, which may include an internal combustion engine or a hybrid drive unit. In addition, the power train 10 has a clutch structure 14 which is connected to the drive motor 12 on the input side. The clutch structure 14 is connected to a stepped transmission 16 on the output side, and the stepped transmission can be constructed in an intermediate shaft structure, for example.

[0061] The stepped transmission 16 and the clutch structure 14 may also be formed by a transducer-automatic transmission.

[0062] The output end of the stepped transmission 16 is connected to the differential 18, and the driving power is distributed to the two driven wheels 20L, 20R by means of the differential.

[0063] The clutch structure 14 includes a friction clutch 22, of which, for example, a dry clutch or a wet clutch in the form of a plate clutch may b

Abstract

The present invention discloses a coupling assembly, a motor vehicle power train and a coupling control metho. The coupling assembly (14) for the motor vehicle power train (10) includes: friction coupling (22) and a hydraulic actuator configuration (24) which is used for operating the frictio coupling (22), wherein the actuator configuration (24) has a hydraulic cylinder (36), a pump (28) and an electric motor (26), the electric motor (26) driving the pump (28), a press-out connecting portion (32) of the pump (28) is in direct connection with the hydraulic cylinder (36) via a pressure pipeline (44). Pressure (P) provided by the pump (28) in the pressure pipeline (44) can be regulated through adjustment of the rotating velocity (n) of the electric motor (26). The press-out connecting portion (32) is connected to a low pressure region (34) by means of a hydraulic branch (48) and is provided with a device (50) which constrains a flowing in the hydraulic branch (48). Here, the hydraulic branch (48) is provided with a valve (52) which can be operated to impose further constraints on the flowing which passes the hydraulic branch (48).
