Coolant distribution device

Abstract

A coolant distribution device for a wet-running clutch device and comprising several coolant distribution surfaces along which coolant is conveyed outwards in the radial direction. In order to increase the service lifetime of a wet-running clutch device the coolant distribution surfaces are implemented so that the coolant conveyed outwards in the radial direction has different axial coolant spray-off points and/or coolant spray-off devices.

Claims

1. A coolant distribution device for a wet-running clutch device (56) comprising several coolant distribution surfaces (21-23) along which coolant is conveyed outwardly in the radial direction, wherein the coolant distribution surfaces (21-23) are implemented so that the coolant conveyed outwardly in the radial direction have different axial coolant spray-off points and/or coolant spray-off devices.

2. The coolant distribution device recited in claim 1, wherein the coolant distribution surfaces (21-23) are provided on ramps which, on the outside in the radial direction, have, as seen in the circumferential direction, different slopes.

3. The coolant distribution device recited in claim 1 wherein the coolant distribution surfaces (21-23) are bounded by ribs (25-28).

4. The coolant distribution device recited in claim 1 wherein the coolant distribution device (1) comprises a coolant distribution element (20) which essentially has the shape of an annular disk and on which the coolant distribution surfaces (21-23) are provided.

5. The coolant distribution device recited in claim 1 wherein the coolant distribution device (1) comprises a drive sleeve (32).

6. The coolant distribution device recited in claim 1 wherein the drive sleeve (32) comprises coupling elements (34, 35).

7. The coolant distribution device recited in claim 1 wherein the coolant distribution device (1) comprises a receiving plate (2).

8. The coolant distribution device recited in claim 7 wherein the receiving plate (2) comprises coupling elements (5-7) on the outside in the radial direction.

9. The coolant distribution device recited in claim 1 wherein the coolant distribution surfaces (21-23) have a sharp edge on the outside in the radial direction.

10. A wet-running clutch device (6) comprising, on the driving side and the driven side, friction units which are formed of, alternating in layers in the axial direction on the driving side and the driven side, a plurality of friction partners which can be pressed against one another in the axial direction to produce a frictional engagement, and with a coolant distribution device (1) comprising several coolant distribution surfaces (21-23) along which coolant is conveyed outwardly in the radial direction, wherein the coolant distribution surfaces (21-23) are implemented so that the coolant conveyed outwardly in the radial direction have different axial coolant spray-off points and/or coolant spray-off devices.
