A shaft assembly for a dual clutch transmission system to be installed in a power train of a motor vehicle for selectively coupling three rotating transmission members. The shaft assembly extends along a central axis and includes a transmission member having first and second axial ends relative to the central axis. The first axial end is rotatably connected to a shaft part, and a bore extends along the central axis from the first axial end in a direction towards the second end. The bore is open at the first end and includes a closed bore end opposite the first axial end. The bore includes a stepped closed bore end section in which a diameter of the bore decreases stepwise towards the closed bore end. Improved clutch assemblies, annular drive plates for a clutch assembly and method of manufacturing thereof, dual-clutch assemblies, and clutch subassemblies for assembly into a transmission system.

Shaft assembly for use in a dual clutch transmission system for improved lubrication and other improved parts of transmission systems

A dual clutch transmission for a motor vehicle power train for selectively coupling rotating transmission members includes a base assembly, a bearing mounted rotating assembly which is rotatable with respect to the base assembly, first and second torque transmission assemblies movable between disengaged and engaged positions, and first and second actuation mechanisms associated with the first and second torque transmissions assemblies. The actuating mechanisms are arranged for moving the respective torque transmission assemblies between the disengaged and engaged positions for selectively coupling the transmission members. The first torque transmission assembly couples two rotating members in the engaged position. The first actuating mechanism includes a hydraulic actuating mechanism having a piston chamber and a piston for moving the first torque transmission assembly between the disengaged and engaged positions. The piston chamber is arranged in the base assembly, and the piston actuates the first torque transmission assembly in the rotating assembly.
