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

Dual clutch transmission system, vehicle and method of cooling. A dual clutch transmission system, including coaxial first and second engageable and disengageable torque transmitting assemblies, configured to be installed in a power train of a vehicle, the system including a main flow path for supply of cooling fluid, wherein the main flow path branches into a first flow path for supply of cooling fluid to the first torque transmitting assembly, and a second flow path for supply of cooling fluid to the second torque transmitting assembly, wherein the system includes a third flow path for supplying cooling fluid, which is discharged from the second torque transmitting assembly, to the first torque transmitting assembly, the third flow path preferably being arranged within a space defined by a housing of the dual clutch transmission system.
