ABSTRACT:
A starter for a motor vehicle comprises an electric motor having an output shaft which drives a coaxial starter head through a speed reducer. The speed reducer incorporates an epicyclic gear train, including a cylindrical casing within which the internally toothed crown wheel of the epicyclic gear train is mounted in rotation. The crown wheel is coupled in rotation to the casing through a friction type torque limiting device, which is interposed axially between the crown wheel and a transverse plate of the casing. The torque limiting device includes at least one annular transverse friction surface of the crown wheel, which is biased elastically into axial engagement against a reaction surface coupled in rotation to the casing.
