Abstract
A hydraulic torque converter comprises a housing (G), in which two vane cell stator/rotor sets (SR1, SR2) are arranged one behind the other. The two sets are in hydraulically communicating connection with one another. The rotors (6, 6′) are connected to a driveshaft (P) or an output shaft (M). The stators (7, 7′) are at a spacing from the associated rotors (6, 6′), and the spacing can be varied in at least one radial direction on the basis of pressure and/or centrifugal force, wherein means (75, 76, 77) are present in order to regulate the spacing from the associated rotor (6, 6′). This enables an inexpensive production of a continuously variable transmission which is, in addition, easy to regulate and has an optimized transmission of force.
