Problems solved by technology

[0007] Of course, in transmissions and drive trains in which such stop functions are not used, additional losses and thus additional heat inputs can also occur due to the flow of cooling oil, since the oil is continuously fed from the oil chamber into the clutch. This oil is accelerated and moved and then churned again in the pool, although cooling may not be necessary in the driving situation involved

Embodiment Construction

[0031] exist Figure 1a and 1b The clutch unit described in has an integrated metering device for the cooling fluid used for cooling and lubricating the friction clutches of the clutch unit. The friction clutch is not shown here.

[0032] The clutch unit comprises a first ramp ring 10 and a second ramp ring 12 with a plurality of rolling elements 14 interposed therebetween. These elements together with associated drive means, such as an electric motor, not shown, form the actuator 16 for the friction clutch. The second beveled ring 12 is here stationary (that is to say torsionally fixed and fixed in the axial direction), whereas the first beveled ring 10 is rotatable and axially fixed relative to the second beveled ring 12 . is movable. Alternatively, it is also possible, for example, for the two ramp rings 10 , 12 to rotate in opposite directions, wherein the second ramp ring 12 is supported in the axial direction and the first ramp ring is additionally movable in the axia...

Abstract

A clutch unit for a motor vehicle, comprising a friction clutch and an actuator for operating the friction clutch, wherein the actuator has a first bevel ring and a second bevel ring, at least one of the bevel rings One is rotatable relative to the other bevel ring in order to apply an axial force to the friction clutch. The clutch unit furthermore includes a metering device for metered delivery of cooling fluid to the friction clutch. The dosing device has a first dosing section and a second dosing section, the first dosing section being associated with the first bevel ring, and the second dosing section being associated with the first bevel ring. Two beveled rings are associated, wherein the first dosing section and the second dosing section together define a dosing opening for the cooling fluid. The first dosing section and the second dosing section act together so that the cross-section of the dosing opening bounded by the dosing section can be changed by relative rotation of the bevel ring.

Description

technical field [0001] The invention relates to a clutch unit for a motor vehicle, having: a friction clutch; an actuator for actuating the friction clutch, wherein the actuator has a first ramp ring and a second ramp ring, the first ramp At least one of the ring and the second ramped ring is rotatable relative to the other ramped ring to apply an axial force to the friction clutch; and there is a metering device for metering cooling fluid to the friction clutch. Background technique [0002] Clutch units of this type are used in the drive train of motor vehicles for the selective transfer of torque. For this purpose, a friction clutch is provided, which is generally designed as a multidisk clutch and enables a continuously variable transmission of torque. The associated actuator is designed such that it exerts a force axially on the friction clutch. For this purpose, two bevel rings are used which, distributed over the circumference, have a plurality of bevels which are i...
