摘要

Improvements in mechanisms for speed changes, characterized in that the input shaft, through a hydraulic clutch, rotates a gear wheel, which permanently meshes with another, integral with an auxiliary shaft, which in turn interlocked several others of different numbers of teeth, facing and in gear with other so many mounted crazy on the output shaft and equipped with an automatic device, by centrifugal force, locking on said output shaft, depending on the speed of rotation of the same, that causes that the pair of gears, one of the auxiliary axis and another one of the one of exit, that forms part in each case of the train of transmission, goes being being that corresponds to the value of the speed, effecting the change releasing the accelerator to accelerate again.
