Actuation device for a transmission system includes an electric motor kinematically connected to a speed reducer and an output shaft of the speed reducer of axis of rotation, the output shaft being arranged to pivot through three adjacent angular sectors, a first angular sector, a second angular sector adjacent to the first angular sector, and a third angular sector adjacent to the second angular sector. An actuation cam is rigidly connected to the output shaft for rotation therewith. A receiving part is axially movable along a main axis perpendicular to the axis of rotation, comprising a receiving recess for receiving the actuation cam formed by two surfaces parallel to each other and perpendicular to the main axis.

Actuation device for a transmission system

A blocking mechanism including a transmission casing and a movable pawl having a locking finger. The movable pawl is pivotably mounted in a plane about a pivot axis on the transmission casing 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 the locking recess. The movable pawl includes a cam surface. A linear actuator moves a movable carriage guided by a guide rail, in which the movable carriage includes a cam follower capable of moving on the cam surface, and a housing formed in the transmission casing, in which the guide rail is fitted in the housing.

Blocking mechanism

A gearbox includes a transmission casing and a blocking mechanism for a vehicle. The blocking mechanism includes a pawl having a locking finger able to be engaged in a locking recess, an actuator which moves a mobile carriage having first and second rollers, and a guide rail attached to the casing. The guide rail forms an attachment wall and a guide wall, the first roller being placed in contact with the second roller and with the pawl, and the second roller being placed in contact with the guide wall. The guide rail is attached to the casing by an attachment mechanism, the guide rail and the attachment mechanism collaborating in such a way that the attachment wall is held against the casing while being able to be moved relative to this same attachment mechanism.
