Abstract

A damping mass (25) for increased gear shifting comfort, fixedly disposed on a control shaft (24) of a motor vehicle gearbox. The control shaft (24) is coupled to at least one gear shift fork disposed in the gearbox and to a gear shift lever for manual selection of a gear in the gearbox. In the damping mass (25) , a cavity (28) extends substantially along a predetermined radius at a distance from the geometrical center (29) of the control shaft. The cavity is filled with a fluid (30) with predetermined viscosity. A body (23) having a certain predetermined weight is designed to move preferably along said radius in the cavity (28) , with a view to maintaining good gear shifting comfort accompanied by a reduction in torque stress over the control shaft (24).
