Abstract
A blocking mechanism includes a mobile pawl mounted with the ability to pivot between a locking position and a release position. The mobile pawl includes a cam surface, a pushing device including a cam follower able to move on the cam surface in order to move the mobile pawl from the release position to the locking position, and an actuating lever moving the pushing device and including a first notch and a second notch. A positioning member engages in the first notch in the locking position and in the second notch in the release position. The positioning member includes a first fixing surface and a second fixing surface which are offset from one another axially.
Claims20
A blocking mechanism able to be mounted in a transmission casing for rotationally blocking a shaft of a vehicle having at least one locking recess, the blocking mechanism comprising:
- a mobile pawl comprising a locking finger, the mobile pawl being mounted with the ability to pivot about an axis of pivoting between a locking position in which the locking finger is engaged in the locking recess and a release position in which the locking finger is disengaged from said locking recess, the mobile pawl comprising a cam surface;
- a pushing device including a cam follower able to move on the cam surface in order to move the mobile pawl from the release position to the locking position;
- an actuating lever mounted with the ability to pivot about an axis of actuation and configured to move the pushing device, the actuating lever comprising an external periphery including a first angular-positioning notch and a second angular-positioning notch;
- and
- a positioning member collaborating with the external periphery of the actuating lever, the positioning member including a bearing surface configured to engage in the first angular-positioning notch when the mobile pawl is in the locking position and in the second angular-positioning notch when the mobile pawl is in the release position;
- wherein the positioning member comprises a first fixing surface and a second fixing surface, the first fixing surface and the second fixing surface being offset from one another in a direction parallel to the axis of actuation.

- a positioning member collaborating with the external periphery of the actuating lever, the positioning member including a bearing surface configured to engage in the first angular-positioning notch when the mobile pawl is in the locking position and in the second angular-positioning notch when the mobile pawl is in the release position;
- wherein the positioning member comprises a first fixing surface and a second fixing surface, the first fixing surface and the second fixing surface being offset from one another in a direction parallel to the axis of actuation, and
- wherein:
- a first fixing means collaborates with the first fixing surface in order to limit the movement of the positioning member in a plane perpendicular to the axis of actuation;
- and
- a second fixing means collaborates with the second fixing surface to block the movement of the positioning member along an axis parallel to the axis of actuation.
