A method for the mounting, in the correct relative angular position, of a pair of rotary drums of a double-drum sequential gear control device for a motor-vehicle gearbox

摘要

To ensure the mounting in the correct relative angular position of a first drum (10) and of a second drum (16) of a double-drum sequential gear control device for a motor-vehicle gearbox, wherein, in the mounted condition, the first drum (10) is rotatable about a first rotation axis (X1) and the second drum (16) is rotatable about a second rotation axis (X2) parallel to the first rotation axis (X1), a mounting method is proposed which comprises the steps of: forming a positioning hole (52) in a given position of the first drum (10) and a positioning hole (56) in a given position of the second drum (16); arranging the first and second drums (10, 16) in a predefined relative angular position; locking the first and second drums (10, 16) in that relative angular position by engaging their positioning holes (52, 56) by means of pins (62, 64); and disengaging the pins (62, 64) from the positioning holes (52, 56) of the first and second drums (10, 16) once the mounting of the gear control device is completed.
