1. Multi-clutch transmission for motor vehicle with at least one prime mover, the multi-clutch transmission comprising
frictional clutches drivingly connected to the prime mover, an output shaft, and a main transmission comprising input shafts connected to the frictional clutches, a countershaft parallel to at least one of the input shafts, gearwheels, tooth clutches, and a central synchronizing unit, where by selective engagement of the frictional clutches and tooth clutches, different speed ratios between the prime mover and the output shaft can be established, and by selective actuation of the central synchronizing unit, engagement of the tooth clutches can be facilitated, the central synchronizing unit comprising an axially moveable synchronizing member that is arranged on and rotationally locked with the countershaft, in actuated states of the central synchronizing unit, the synchronizing member is displaced axially into engagement with mating portions of two of the gearwheels that are rotatably arranged on the countershaft, wherein the synchronizing member comprises an internal and an external conical friction surface that axially overlap each other, and the mating portions on the two of the gearwheels are mating conical surfaces, where on both of the two of the gearwheels, gear teeth of the two of the gearwheels axially overlap the mating conical surface, and where the synchronizing, member is actuated by an actuator via a control rod that is arranged in a coaxial bore of the countershaft and the actuator is non-rotating, the control rod rotates with the countershaft, and there is an axial connecting device between the actuator and the control rod. |
