Abstract
A vehicle gearbox has a brake for dampening idle rattling, which is in this case in the form of a conical frictional surface on the low-speed gearwheel on the output shaft and a brake cone carried by a disc fixed to the output shaft. The disc and the cone have coacting structure which presses the cone against the frictional surface when the low-speed gearwheel rotates more rapidly than the output shaft, and which presses the cone away from the frictional surface when the shaft rotates more rapidly than the gearwheel.
