## Abstract

A bushing-type roller overrunning clutch comprising at least an inner or an outer ring that comprises clamping ramps adapted to the needles or rollers, said overrunning clutch further comprising a cage for the needles or rollers, as also pressure springs, said cage comprising cage elements that are made in one piece with the inner or outer ring, and a method of making a bushing-type roller overrunning clutch in which the inner or outer ring together with the clamping ramps and at least one border arranged on one side of the clamping ramps is made by deep-drawing, spring-retaining lugs are cut out of the border, and the spring-retaining lugs are bent radially towards the inner or outer ring and the free-standing tabs of the spring-retaining lugs are bent over into the region of the clamping ramps.

## Claims

### Claim 1

A bushing-type roller overrunning clutch comprising at least an inner or an outer ring comprising clamping ramps adapted to the needles or rollers, said overrunning clutch further comprising a cage for the needles or rollers, and pressure springs, wherein said cage comprises cage elements that are made in one piece with the inner or outer ring and the cage elements are configured as spring-retaining lugs and are arranged laterally on the inner or outer ring.

### Claim 2 (depends on 1)

A bushing-type roller overrunning clutch of claim 1, wherein the spring-retaining lugs comprise free-standing tabs that are arranged inside or outside of the inner or outer ring and are adjacent to the clamping ramps.

### Claim 3 (depends on 1)

A bushing-type roller overrunning clutch of claim 1, wherein on a side turned away from the spring-retaining lugs, the inner or outer ring comprises an annular shoulder.

### Claim 4

(canceled)

### Claim 5 (depends on 1)

A method of making a bushing-type roller overrunning clutch, with a cage, of claim 1 comprising
deep-drawing the inner or outer ring together with the clamping ramps and with at least one border arranged on one side of the clamping ramps,
cutting spring-retaining lugs out of the border, and
bending the spring-retaining lugs radially towards the inner or outer ring and bending the free-standing tabs of the spring-retaining lugs over into the region of the clamping ramps.

### Claim 6 (depends on 1)

A method of making a bushing-type roller overrunning clutch, with a cage of claim 1 comprising
deep-drawing the inner or outer ring together with the clamping ramps to make as a generally pot-shaped component,
cutting out the tabs of a bottom rim adjoining the clamping ramps, and
bending over the tabs into the region of the clamping ramps.

### Claim 7 (depends on 5)

The method of claim 5 wherein
the borders are integrally formed on the inner or outer ring on the side opposite to the border or the bottom rim, and
the border is bent over radially to form an annular shoulder.

### Claim 8 (depends on 5)

The method of claim 5 wherein the inner or outer ring is pressed onto or into a support ring.

### Claim 9 (depends on 5)

The method of claim 5 wherein a collar projecting radially inwards or outwards is formed integrally on the support ring, before the support ring is pressed together with the inner or outer ring.
