Embodiment Construction

[0066] exist figure 1 A drive train of a motor vehicle is schematically shown in and generally designated 10 . The drive train 10 has a drive motor 12 which can be designed, for example, as an internal combustion engine, but also as a hybrid drive unit. Furthermore, the drive train 10 includes a clutch device 14 , which is coupled on the input side to the drive motor 12 and which is coupled on the output side to the transmission device 16 . The clutch device 14 can be a single clutch, but also a double clutch device. The output of the transmission device 16 is connected to a differential 18 by means of which the drive power can be distributed to the driven wheels 20L, 20R.

[0067] The transmission device 16 can be an automatic shift transmission, but also a dual clutch transmission with two subtransmissions not shown in detail. exist figure 1 The longitudinal axis of the drive train 10 is indicated by 22 in the middle, which can coincide with the longitudinal axis of the ...

Abstract

A pump device (32) for a motor vehicle drive train (10) having a first pump (42) configured to provide a first pump pressure (P 1 ), the first pump pressure is sufficient to hydraulically operate at least one drive train component (14, 16), wherein the first pump (42) is connected to a drive member (44) configured to be driven by the drive train (10 ) driven by a drive motor (12); and has a second pump (48) configured to provide a second pump pressure (P 2 ), wherein the second pump (48) is connectable to the motor (50). Here, the first pump and the second pump (42, 48) are fastened to a common pump unit housing (46), which forms an interior space for mounting in a drive train housing (80) ( 88).

Description

technical field [0001] The invention relates to a pump arrangement for a drive train of a motor vehicle having a first pump designed to provide a first pump pressure sufficient to hydraulically actuate at least one drive train component , wherein the first pump is connected to a drive member configured to be driven by the drive motor of the drive train; and has a second pump configured to provide a second pump pressure, wherein the second pump is capable of Connect with the motor. [0002] Furthermore, the invention relates to a hydraulic device for a motor vehicle drive train having a pump device of the mentioned type and having a valve device with a pressure connection of a first pump and with a pressure connection of a second pump connected, wherein the valve arrangement is also connected to at least one hydraulic actuator for actuating the drive train component. [0003] Finally, the invention relates to a drive train for a motor vehicle with such a pump device or with s...
