ABSTRACT:
The invention relates to a control device for controlling the engagement of desired gears of a gearbox, which control device comprises a control rod with a relating locking arrangement. The locking arrangement comprises 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 comprises a resilient locking means arranged in a recess in the control rod, which locking means has a locking portion which, against the action of a spring force of the locking means, is arranged for movement in said recess in the control rod's radial direction between a protruded position in which the locking portion engages in one of said grooves/recesses in the locking element and thereby counteracts movement of the control rod relative to the locking element, and a retracted position in which the locking portion does not engage in any of said grooves/recesses in the locking element. The invention also relates to a gearbox comprising such a control device.
