Abstract

A torque converter comprises a pump rotor, a turbine rotor, and a stator. The turbine rotor is fixed to a gearbox input shaft. The gearbox input shaft forms an axial duct with an initial zone and an end zone for a hydraulic fluid. The gearbox input shaft further comprises a shaft core and a shaft sleeve, surrounding the shaft core, fixed against rotation to each other. The shaft core and shaft sleeve are matched to each other in such a manner that the shaft core runs radially in the shaft sleeve with no play and the shaft core and the shaft sleeve together form the axial duct.
