Coolant distribution device
View Patent ↗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.
1. A coolant distribution device for a wet-running clutch device ( 56 ) comprising an annular disk-shaped distribution element ( 20 ) including:
a plurality of curved ribs ( 25 - 28 ) extending from the annular distribution element ( 20 ) in a direction parallel to an axis of rotation for the coolant distribution device; and,
a plurality of coolant distribution surfaces ( 21 - 23 ) along which coolant is conveyed outwardly in the radial direction, wherein the coolant distribution surfaces ( 21 - 23 ) are configured so that the coolant conveyed outwardly along at least one of the coolant distribution surfaces is directed to a different axial position than the coolant conveyed outwardly alonci another of the coolant distribution surfaces.
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 drive sleeve ( 32 ).
5. The coolant distribution device recited in claim 4 wherein the drive sleeve ( 32 ) comprises coupling elements ( 34 , 35 ).
6. The coolant distribution device recited in claim 1 wherein the coolant distribution device ( 1 ) comprises a receiving plate ( 2 ).
7. The coolant distribution device recited in claim 6 wherein the receiving plate ( 2 ) comprises coupling elements ( 5 - 7 ) on the outside in the radial direction.
8. 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.
9. A wet-running clutch device ( 56 ) comprising, on the driving side and the driven side, friction units which are formed of, alternating in layers in an axial direction, parallel to an axis of rotation for the clutch device ( 56 ), 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 an annular receiving plate ( 2 ) disposed in line with at least a portion of the friction partners in the axial direction, the annular receiving plate ( 2 ) disposed, in a radial direction orthogonal to the axial direction, outside of a plurality of coolant distribution surfaces ( 21 - 23 ) along which coolant is conveyed outwardly in the radial direction, wherein the coolant distribution surfaces ( 21 - 23 ) are configured so that the coolant conveyed outwardly along at least one of the coolant distribution surfaces is directed to a different axial position than the coolant conveyed outwardly along another of the coolant distribution surfaces.
