Abstract

An overrunning clutch unit may include inner and outer rings that can be rotated relative to each other. Clamping members may transmit a torque between the two rings in one peripheral direction, the clamping members being arranged between the rings. A first bearing device may be configured to support the two rings, wherein the first bearing device is arranged between the rings at a first axial side of the clamping members. A second bearing device may be configured to support the two rings, wherein the second bearing device is arranged at a second, opposing, axial side of the clamping members so that a tilting of the inner ring relative to the outer ring is prevented.

First claim

What is claimed is:

1. An overrunning clutch unit, comprising:
an overrunning clutch system inner ring and an overrunning clutch system outer ring, the overrunning clutch system inner ring being arranged coaxially in relation to a rotation axis (D) with respect to the overrunning clutch system outer ring, and wherein the overrunning clutch system inner ring and the overrunning clutch system outer ring can be rotated relative to each other;
a plurality of clamping members configured to transmit a torque between the two overrunning clutch system rings in one peripheral direction, wherein the clamping members are arranged between the overrunning clutch system inner ring and the overrunning clutch system outer ring;
a first bearing device configured to support the two overrunning clutch system rings, wherein the first bearing device is arranged between the overrunning clutch system inner ring and the overrunning clutch system outer ring at a first axial side of the clamping members; and
a second bearing device configured to support the two overrunning clutch system rings, wherein the second bearing device is arranged at a second, opposing, axial side of the clamping members so that a tilting of the overrunning clutch system inner ring relative to the overrunning clutch system outer ring is prevented, wherein the second bearing device is a plain bearing device connected to the overrunning clutch system inner ring or the overrunning clutch system outer ring by a snap-fit connection.

2. The overrunning clutch unit as claimed in claim 1 , wherein the first bearing device is a roller bearing device.

3. The overrunning clutch unit as claimed in claim 1 , wherein the second bearing device is connected to a first of the two overrunning clutch system rings, wherein the second bearing device has a first sliding face and wherein the second of the two overrunning clutch system rings has a second sliding face, wherein a plain bearing contact is formed between the first and the second sliding faces.

4. The overrunning clutch unit as claimed in claim 3 , wherein the second bearing device and/or the plain bearing contact is dry lubricated and/or lubricated by a lubricant.

5. The overrunning clutch unit as claimed in claim 3 , wherein the second bearing device has a sleeve portion and a collar portion, wherein the second bearing device is connected by the collar portion to the first of the two overrunning clutch system rings, wherein the sleeve portion has the first sliding face and is in abutment with the second of the two overrunning clutch system rings.

6. The overrunning clutch unit as claimed in claim 1 , wherein the second bearing device is formed from a non-ferrous heavy metal.

7. The overrunning clutch unit as claimed in claim 1 , wherein the second bearing device has an active contour and the overrunning clutch system inner ring or the overrunning clutch system outer ring has a counter-contour, wherein the active contour and the counter-contour form the snap-fit connection.

8. A gear mechanism device having the overrunning clutch unit as claimed in claim 1 .
