Embodiment Construction

[0025] figure 1 Shown is a switching unit 1 for supplying cooling oil to a first clutch 2 and a second clutch 3 which can be selectively closed in order to transmit torque from a common drive shaft 4 to either Either to the first driven shaft 5 or to the second driven shaft 6 . In this case, the first clutch 2 can connect the drive shaft 4 to the first output shaft 5 in a torque-transmitting manner, while the second clutch 3 can connect the drive shaft 4 to the second output shaft 6 .

[0026]The switching unit 1 has a slide 7 and fluid channels 8 , 9 , 10 , 11 , 12 coupled thereto, which are placed in an operative relationship with one another in such a way that the switching unit 1 relies on the two Which of the clutches 2 , 3 is in a torque-transmitting connection to the first output shaft 5 or the second output shaft 6 supplies cooling oil to the selected clutch 2 , 3 .

[0027] The two clutches 2 , 3 are part of the hybrid module 13 . In the hybrid module 13 , a torsio...

Abstract

The invention relates to a switching unit (1) for supplying cooling oil to two clutches (2, 3) which can be selectively closed in order to transmit torque from a drive shaft (4) to either Either on the first driven shaft (5) or to the second driven shaft (6), wherein the switching unit (1) has a slide (7) and a fluid channel (8, 9, 10 coupled thereto) . The drive shaft (6) is torque-transmittingly connected to deliver cooling oil to selected clutches (2, 3). The invention also relates to a hybrid module (13) for a drive train of a motor vehicle, the hybrid module having two clutches (2, 3) and such a shifting unit (1).

Description

technical field [0001] The invention relates to a shifting unit for supplying cooling oil to two (sub)clutches, such as a double clutch, which can be selectively closed in order to transmit torque from a common drive shaft to either Either to the first driven shaft or to the second driven shaft. That is to say, only one of the two clutches is always engaged, ie transmits torque, while the other of the two clutches is open. The invention also relates to a hybrid module for a drive train of a motor vehicle, the hybrid module having in particular a P1 hybrid device, ie a hybrid device in which the electric machine is fastened to the crankshaft of the internal combustion engine, the P1 - The hybrid device has two (sub)clutches and such a switching unit. Background technique [0002] Clutch arrangements with cooling oil switching units are already known from the prior art. For example, DE 10 2016 202 656 A1 discloses a clutch device with: first and second friction elements, wh...
