摘要

The device (100) has a switching device (110) selecting and inserting gears of multiple gears of a gear box, where the gears comprise predetermined gears and gears set, and the locking device inhibits lying of predetermined gears in an off state. The locking device is moved into the off state by inlaying of the gears. The switching device comprises a control structure, a block component (120) and a locking surface (200) connected with the block component. A spring element (250) exerts force on the block component along a movement direction (140).
