Abstract:
1. A dual clutch transmission for a motor vehicle having a synchronizer actuation interlock system including: a pair of input shafts; a counter shaft; a plurality of gear sets rotatively disposed on said pair of input shafts and said counter shaft, said plurality of gear sets adapted to be operatively engaged to and disengaged from their respective shafts; a plurality of synchronizers disposed about said gear sets, said plurality of synchronizers adapted to operatively engage and disengage said gear sets to and from their respective shafts; a plurality of hydraulically actuated shift actuators each operatively connected to one of said plurality of synchronizers, each of said plurality of shift actuators adapted to cause the associated synchronizer to engage and disengage the associated gear sets to and from the associated shaft and further adapted to provide a hydraulic interlock that prevents an associated shift actuator on the same shaft from hydraulically actuating when said shift actuator is already in engaged position.
