Gearbox

摘要

This gearbox whose arrangement is derived from that of motorcycle gearboxes, comprises organs according to the invention enabling it to be adapted, in particular for a motor vehicle. The selector shaft (10) which ensures the ratio shift by means of forks (29, 30, 31) may be decoupled from the latter thanks to a decoupling shaft (11) which disengages the counter-cams forming one piece with the forks from their respective cams provided on the selector shaft (10). One can thus select any ratio shift without having to shift through the intermediate ratios.
