ABSTRACT:
The invention relates to a control device for controlling the engagement of selected gears of a gearbox for a motor vehicle, which control device comprises a control rod with a respective locking arrangement. The locking arrangement includes a locking element provided with one or more grooves or recesses which each define a predetermined setting position of the control rod. The locking arrangement further includes two locking balls, a control ball and a spring arranged in a hollow space in the control rod. The locking balls are movable radially in the hollow space in mutually opposite directions, perpendicular to the control rod's longitudinal axis, against the action of the spring in order for the locking balls to be brought into and out of engagement with the grooves/recesses. The control ball is movable in the hollow space in the control rod's axial direction and is preloaded by the spring against the locking balls so that the locking balls, through the action of the spring and the control ball, are thereby preloaded to assume a protruded position in order to engage in one of the grooves/recesses. The invention also relates to a gearbox including such a control device.
