Abstract: A friction disk for a wet-running clutch for a motor vehicle includes a lining carrier ring, provided with connecting areas for connecting the friction disk to a drive side or to a takeoff side of a clutch, and a plurality of friction lining elements, carried on at least one side of the lining carrier ring, Fluid flow channels are provided between the friction lining elements which are directly adjacent to each other in the circumferential direction, wherein at least some of the fluid flow channels have different channel widths.

Abstract: A hydrodynamic torque converter includes a pump wheel with a plurality of pump wheel vanes arranged in a row in the circumferential direction around an axis of rotation; a turbine wheel, which can rotate relative to the pump wheel around the axis of rotation and which has a plurality of turbine wheel vanes arranged in a row in the circumferential direction around the axis of rotation; and a stator with a plurality of stator vanes arranged in a row in the circumferential direction around the axis of rotation. The pump wheel, the turbine wheel, and the stator define a hydrodynamic circuit with an outside diameter Da, an inside diameter Di, and a maximum axial length La, where (1) Di/Da<0.58 and (2) Da5?5.2?1×1010×M, where M is the maximum torque in Nm to be transmitted via the hydrodynamic torque converter, and Da is the outside diameter of the hydrodynamic circuit in mm.
