Hydrodynamic torque converter

摘要

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 D_a, an inside diameter D_i, and a maximum axial length L_a, where (1) D_i/D_a<0.58 AND (2) D_a⁵<=5.2^-1x10¹⁰xM, where M is the maximum torque in Nm to be transmitted via the hydrodynamic torque converter, and D_a is the outside diameter of the hydrodynamic circuit in mm.
