Shifting device for a transmission with coaxial tubes

摘要

The motor vehicle drive transmission has selector fork shafts (21-23) each having a notch (211-231) and a drive pin (10) to move a respective fork with the co-operation of the respective notch. The notches define apertures which are superimposed when the tubular shafts are superimposed when the tubular shafts are assembled concentrically. Each notch has a free area (212-232) in which a pin (10) can move without engaging the notch. The notch of each opening is superimposed over the free area of each of the other openings. The pin has rotary and translational movement to engage the notches.
