Abstract
The motor vehicle starter ( ) has a casing ( ) in which there is arranged an electric motor ( ) which rotates a coaxial starter head ( ) with the interposing of an epicyclic gearbox ( ) including a ring gear ( ) made of rigid material (M ) which is housed at least partially in a cavity ( ) in the casing and which has an internally toothed cylindrical annular skirt ( ) closed at its front axial end by a radially oriented transverse wall ( ) with a hole at its centre ( ) for the output shaft ( ) of the gearbox to pass; the ring gear ( ) has pins (P) moulded from a flexible material (M ), notably elastomer material, which are interposed between the ring gear ( ) and complementary portions ( ) of the cavity ( ) of the casing ( ) in order to immobilise the ring gear ( ) rotationally with respect to the casing ( ) and provide a function of torsion damping between these two components ( ).
