Abstract
The invention proposes a planet carrier (50) for a planetary gear train of a reducing mechanism of an electromechanical actuator for actuating a parking brake of a motor vehicle, which carries planet pinions (52), each of which is accommodated between two parallel support plates (56, 58) belonging to a reinforcement (54) of the planet carrier and each of which is mounted in rotation on the planet carrier (50) about a rotation guide pin (74) that is mounted between the two support plates (56, 58) to which it is linked by the two opposing axial ends thereof, characterized in that each rotation guide pin (74) is a tubular pin.
Claims20
A planet carrier for a planetary gear train of a reducing mechanism of an electromechanical actuator for actuating a parking brake of a motor vehicle, which planet carrier carries planet pinions, each of which:
- is accommodated between two parallel support plates belonging to a frame of the planet carrier;
- and is mounted rotatably on the planet carrier about a rotation guide pin that is mounted between the two support plates to which it is linked by the two opposite axial ends thereof,
- wherein each rotation guide pin is a tubular pin, and the frame is produced by molding.
A method for assembling a planet carrier, for a planetary gear train of a reducing mechanism of an electromechanical actuator for actuating a parking brake of a motor vehicle, which planet carrier carries planet pinions, each of which
- is accommodated between two parallel support plates belonging to a frame of the planet carrier;
- and is mounted rotatably on the planet carrier about a tubular rotation guide pin that is mounted between the two support plates to which it is linked by the two opposite axial ends thereof,
- wherein said method comprises the steps of:
- producing a planet carrier frame;
- introducing at least one planet between the two support plates;
- axially inserting a tubular rotation guide pin successively through a first of the two support plates, the planet and the second of the support plates;
- axially immobilizing the tubular guide pin in rotation in relation to the two support plates.
