Abstract

A hub arrangement for a hydrodynamic torque converter includes a first hub component forming a first hub area with a first connection area connectable with a converter housing of the torque converter, a second hub component forming a second hub area with a second connection area connectable with a lockup clutch of the torque converter, and a fluid channel arrangement having at least one fluid channel connecting a radial inner area of the hub arrangement with a radial outer area. The first hub component and the second hub component contact one another at least in some areas in surface regions thereof which are located opposite one another. A recess arrangement is arranged in at least one of the oppositely located surface regions of the first and second hub components for forming the fluid channel arrangement.
