Abstract:
1. A transmission shift system comprising a synchronizing device for an idler wheel ( 2 ) comprising a sliding sleeve for engaging with the idler wheel ( 2 ), the sliding sleeve ( 6 ) being non-rotatably and axially displaceable on a shaft ( 1 ) by way of a piston ( 10 ) directly connected thereto, the sliding sleeve ( 6 ) is supported by the shaft ( 1 ) via a hub element ( 7 ) and a releasable catch device ( 3 , 8 , 9 ) facilitates axial movement of the sliding sleeve ( 6 ) relative to the hub element ( 7 ), and a synchronizing operation can be implemented as a function of hydraulic pressure supplied to the piston ( 10 ), in a non-switched state, an actuation pressure supplied to the piston ( in a release state, the actuation pressure supplied to the piston ( during an RPM adjustment state, the actuation pressure supplied to the piston (
