Abstract
Provided is a parking lock clutch that can increase the degree of freedom in controlling the rotational position of a selector with a simple structure, and can implement miniaturization, reduced manufacturing costs, and a longer life. A selector 140 configured to switch an operating mode between a lock mode and a free mode has a pocket 143 configured to accommodate a roller 130 in a roller accommodating portion 117 provided on one of the outer ring 110 and the inner ring 120. The pocket 143 is formed to extend in a circumferential direction so that the selector 140 can be rotated further in an unlocking direction from the rotational angle position at which the roller 130 is accommodated in the roller accommodating portion 117.
Claims5
A parking lock clutch comprising:
- an outer ring and an inner ring arranged coaxially so as to be rotatable relative to each other;
- a plurality of rollers arranged between the outer ring and the inner ring;
- a biasing member radially biasing the roller toward a roller accommodating portion provided on one of the outer ring and the inner ring;
- and
- a selector arranged rotatably independent of the outer ring and the inner ring, wherein
- the selector is configured to switch an operating mode between a lock mode, in which the relative rotation of the outer ring and the inner ring is prohibited by sandwiching the roller in a circumferential direction between the roller accommodating portion and a roller support groove provided on the other of the outer ring and the inner ring, and a free mode, in which the relative rotation of the outer ring and the inner ring is permitted by accommodating the roller in the roller accommodating portion,
- the selector has a pocket formed so that the roller can be accommodated in the roller accommodating portion when the operating mode is switched to the free mode, and
- the pocket is formed to extend in the circumferential direction so that the selector can be rotated further in an unlocking direction of the selector from a rotational angle position at which the roller is accommodated in the roller accommodating portion.
