Abstract
Official abstract text for this publication.
A unit includes a thrust washer having a first abutment and a second abutment. The thrust washer is configured to be moved, by rotation, between a first position in which the thrust washer abuts the first abutment and a second position in which the thrust washer abuts the second abutment. The first abutment and the second abutment are formed by at least one pin and at least one recess. The pin is configured to engage in the recesses, and the recess is designed as a groove that extends tangentially around an axis of rotation of a component that is rotatably mounted by way of the thrust washer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A unit comprising: a thrust washer having a first straight surface, the first straight surface forming a first abutment and a second abutment, wherein the thrust washer is configured to be moved, by rotation, between a first position in which the thrust washer abuts a second straight surface and a second position in which the thrust washer abuts the second straight surface, and wherein the first straight surface and the second straight surface are arranged radially offset from one another. 2. The unit of claim 1 , wherein the thrust washer has a third straight surface, and wherein the thrust washer abuts a fourth straight surface in the first position and abuts the fourth straight surface in the second position, and wherein the third straight surface and the fourth straight surface are arranged radially offset from one another. 3. The unit of claim 2 , wherein the first straight surface and the third straight surface are arranged opposite one another relative to a radial center of the thrust washer. 4. The unit of claim 1 , further comprising a planetary wheel, wherein the first straight surface is arranged on an inner lateral surface of the thrust washer and faces inwardly toward an axis of rotation of the planetary wheel. 5. The unit of claim 4 , wherein the second straight surface faces outwardly away from the axis of rotation of the planetary wheel. 6. The unit of claim 1 , wherein the second straight surface is arranged on a planetary pin. 7. The unit of claim 1 , wherein the first straight surface and the second straight surface are parallel to one another in an intermediate position of the thrust washer between the first position and the second position.
