Motor vehicle gearbox with constantly-meshed gears.

摘要

A motor vehicle gearbox with constantly-meshed gears, in which a selector rod (11) is movable axially in opposite directions to effect the engagement of the highest ratio and reverse respectively by means of respective control forks (15, 16). The control fork (15) for the highest ratio is coupled to a slidable coupling sleeve (4) by cooperating conical coupling surfaces (15a, 14a) which diverge in the direction of movement of the selector rod corresponding to the engagemento of reverse in order to brake the gear shaft (1) upon the engagement of reverse.
