ABSTRACT:
In a gear shifting device for the manual transmission of a motor vehicle with a gearshfit lever, with which the individual gear steps can be engaged over a gearshift rod, the gear shifting motion of the gearshift lever is transferred to the gearshift rod in a nonmechanical manner. The movement of the gearshift lever from the neutral position into the gear shifting position takes place in two steps, the first step acting as a preselection step and the function of the second step being to engage the selected gear step. A locking device permits movement of the gearshift lever from the first into the second step only when the necessary conditions exist for engaging the selected gear step perfectly; that is, when the clutch is disengaged and the gear wheels of the gear steps to be engaged are synchronized.
