Abstract

A gear shift mechanism of a gear shift transmission having a plurality of gears is described. A first movable gear shift fork and at least one second movable gear shift fork are provided for engaging gears of the gear shift transmission and assuming a neutral position as well as an engaged position where a gear allocated to a respective one of the first and second gear shift forks is engaged. A locking mechanism comprising a locking element is provided that prevents that both gear shift forks can assume at the same time unintentionally an engaged position. The locking mechanism is designed such that in a locking position a force for moving the first gear shift fork out of its neutral position does not generate a resulting component of force that would force the locking element against the second gear shift fork.
