Wet-running flexible drive
Wet-running flexible drive mechanism ( 1 ) for the transmission of torque having a drive element ( 2, 2 ′) and an output element ( 3, 3 ′), the drive element ( 2, 2 ′) and the output element ( 3, 3 ′) being drive-connected to one another via a flexible drive ( 14 ), the flexible drive ( 14 ) being arranged partially in a lubricant sump ( 4 ), characterized in that at least one guiding element ( 5 ) is arranged in the region of the lubricant sump ( 4 ), the guiding element ( 5 ) being shaped in such a way that a constriction ( 6 ) in the form of a gap which tapers in a wedge-shaped manner is formed between the flexible drive ( 14 ) which is arranged partially in the lubricant sump ( 4 ) and the guiding element ( 5 ).
1. Wet-running flexible drive mechanism for the transmission of torque having a housing, a drive element, and an output element, the drive element and the output element being drive-connected to one another via a flexible drive, the flexible drive being arranged partially in a lubricant and/or coolant sump, wherein the lubricant and/or coolant sump is integrally formed in the housing, wherein at least one guiding element is arranged in a region of the lubricant sump, the guiding element being shaped in such a way that a constriction in the form of a gap which tapers in a wedge-shaped manner is formed between the flexible drive which is arranged partially in the lubricant sump and the guiding element;
wherein the guiding element is fixed to the housing,
wherein the guiding element has a geometry of a wedge-shaped configuration defining a highest point and first and second longitudinal sides on opposite sides of the highest point, and
wherein a first section of the guiding element, starting from the highest point, runs at a more acute angle in the direction of the first longitudinal side than a second section of the guiding element, starting from the highest point, runs in the direction of the second longitudinal side.
2. Wet-running flexible drive mechanism according to claim 1 , wherein the housing has a bulge in the region of the lubricant and/or coolant sump.
3. Wet-running flexible drive mechanism according to claim 2 , wherein the guiding element is arranged at the bulge of the housing.
4. Wet-running flexible drive mechanism according to claim 3 , wherein the guiding element has a first part and a second part, the first part and the second part being configured such that they can be joined along a dividing plane to form the guiding element.
5. Wet-running flexible drive mechanism according to claim 3 , wherein the bulge and the guiding element are configured in one piece.
6. Wet-running flexible drive mechanism according to claim 3 , wherein the guiding element is fastened to the bulge by a connecting element.
7. Wet-running flexible drive mechanism according to claim 6 , wherein the connecting element is joined to the housing in a positive locking manner.
8. Wet-running flexible drive mechanism according to claim 1 , wherein the first and second sections have a concave curvature.
9. Wet-running flexible drive mechanism according to claim 1 , wherein the first section is longer than the second section.
10. Wet-running flexible drive mechanism according to claim 1 , wherein the highest point of the guiding element is offset toward the second longitudinal side relative to a longitudinal center of the guiding element.
11. Wet-running flexible drive mechanism according to claim 1 , wherein the guiding element is arranged at an oblique angle relative to an upper surface of the lubricant sump.
