Abstract
For a 12-speed transmission for utility vehicles in 2×3×2 construction, a shift lever ( ) is proposed which is configured as a universal joint with a shift fork ( ) and a reversing lever ( ). The shift fork is supported pivotally jointly with the transmission while the reversing lever ( ) is pivotally mounted on the shift fork. When the shift fork is actuated, the synchronization movement, which occurs upon engagement in a synchronization block, runs in opposite direction, when the reverse lever is shifted in the same direction. This makes it possible to shift through the six speeds of the main gear in one stroke with successive shift movements in opposite direction.
