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.
Claims8
A hydraulic torque converter, comprising:
- a housing,
- a first vane cell stator/rotor set arranged in the housing, with outer vane piston support, and
- a second vane cell stator/rotor set arranged in the housing, with outer vane piston support,
- a drive shaft having an axial direction,
- an output shaft,
- wherein each cell stator/rotor set comprises a rotor,
- wherein each cell stator/rotor set comprises a stator,
- wherein the rotor of the first vane cell stator/rotor set can be connected to the driveshaft, and the rotor of the second vane cell stator/rotor set can be connected to the output shaft,
- wherein the first and second vane cell stator/rotor sets are in hydraulically communicating connection,
- wherein the first and second vane cell stator/rotor sets are arranged one behind the other in the axial direction of the driveshaft and the output shaft,
- wherein at least one of the stators has a spacing from the associated rotor which can be varied in at least one radial direction on the basis of pressure and/or centrifugal force, and
- wherein spacing adjustment elements are provided for regulating the spacing from the associated rotor,
- wherein the at least one of the stators with variable spacing consists of two sections the position of which with respect to one another can be varied on the basis of pressure and/or centrifugal force,
- wherein four regulation passage openings are present, wherein two regulation passage openings of the four regulation passage openings are arranged in each of the two sections, the two regulation passage openings of one of the two sections are arranged diagonally opposite the two regulation passage openings of another of the two sections,
- wherein the two regulation passage openings arranged in the same section are arranged mirror symmetrically with respect to a center line, wherein the center line intersects the axis of the driveshaft or output shaft and extends vertically with respect to a separation plane of the two sections, and
- wherein a first of the two regulation passage openings of each section regulates an acceleration type of drive and wherein a second of the two regulation passage openings of each section regulates a deceleration type of drive, wherein the two regulation passage openings arranged diagonally opposite one another regulate the same type of drive.
