Bushing-type roller overrunning clutch with a solid outer ring
View Patent ↗A bushing-type roller overrunning dutch comprising an inner and/or outer ring ( 4 ), clamping ramps ( 2 ) adapted to the needles or rollers ( 5 ), a cage ( 6 ), pressure springs ( 7 ) for the needles or rollers ( 5 ), a bushing ( 1 ) with integrally formed clamping ramps ( 2 ), and a solid inner or outer ring ( 4 ) in or on which the bushing ( 1 ) is fixed.
1. Sleeve/roller freewheel with an inner and/or outer ring, with clamping ramps matched to needles or rollers, with a cage and with press-on springs for the needles or rollers, and with a sleeve having said clamping ramps integrally formed thereon, wherein the inner or outer ring is of solid design and the sleeve is fastened thereon or therein, and a component, namely a guide wheel of a torque converter, which surrounds the outer ring and into which the outer ring is inserted in a rotationally fixed manner, the minimum thickness of the outer ring being at least five times the smallest thickness of the sleeve and the torque which can be transmitted between the inner and outer ring being at least 200 Nm.
2. Sleeve/roller freewheel according to claim 1 wherein that surface of the inner or outer ring which faces the sleeve and/or that surface of the sleeve which faces the inner or outer ring are/is of smooth or corrugated design.
3. Sleeve/roller freewheel according to claim 1 wherein the sleeve and the inner or outer ring are supported against each other by means of a press fit.
4. Sleeve/roller freewheel according to claim 1 wherein the sleeve has a radially oriented annular shoulder at least on one side.
5. Sleeve/roller freewheel according to claim 4 wherein the sleeve together with clamping ramps and, if optionally, an annular shoulder is produced by deformation or deep-drawing.
6. Sleeve/roller freewheel according to claim 4 wherein the solid inner or outer ring has a laterally arranged, radially oriented collar which, after the outer ring is joined to the sleeve, is arranged on a side facing away from the annular shoulder of the sleeve.
7. Sleeve/roller freewheel according to claim 1 wherein the sleeve is produced from strip stock with the clamping ramps integrally formed thereon by stamping, and the sleeve is shaped to form a ring, the ends of which are joined together in an abutting relationship.
8. Sleeve/roller freewheel according to claim 1 wherein the outer ring is cast into the surrounding component.
9. Sleeve/roller freewheel according to claim 1 wherein the outer ring is pressed into the surrounding component.
10. Sleeve/roller freewheel according to claim 1 wherein the surrounding component is manufactured from plastic.
11. Sleeve/roller freewheel according to claim 1 wherein the surrounding component is manufactured from light metal.
12. Sleeve/roller freewheel with an inner and/or outer ring, with clamping ramps matched to needles or rollers, with a cage and with press-on springs for the needles or rollers, and with a sleeve having said clamping ramps integrally formed thereon, wherein the inner or outer ring is of solid design and the sleeve is fastened thereon or therein, and a component, namely a flange housing, which surrounds the outer ring and into which the outer ring is inserted in a rotationally fixed manner, the minimum thickness of the outer ring being at least five times the smallest thickness of the sleeve and the torque which can be transmitted between the inner and outer ring being at least 200 Nm.
