The gearbox comprises a primary shaft (100) and at least one parallel secondary shaft (300) supporting several fixed cogs (102,103,400,410,420,430) and several idler pinions (350,310,155,110,150,120) which mesh with the cogs. The idler pinions can be connected to rotate with their shaft by a coupling (325) during engagement of a gear. The means of coupling to an idler gear are fixed to the periphery of a free wheel (360). An INDEPENDENT METHOD is included for a method of controlling gear changes.
