  • Patent number: 7588130
    Abstract: A hydrodynamic clutch device includes a pump wheel, a housing connecting the pump wheel to a drive, a turbine wheel connected to a takeoff, the turbine wheel being located in the housing and cooperating with the pump wheel to form a hydrodynamic circuit, and a bridging clutch located in the housing and having a piston located between the hydrodynamic circuit and a pressure space. The piston is movable between an engaged position and a released position. At least one through opening in the piston allows an exchange of clutch fluid between the hydrodynamic circuit and the pressure space regardless of the position of the piston and a non-return valve allows only flow from the hydrodynamic circuit to the pressure space when the clutch is released.

  • Patent number: 7478713
    Abstract: A hydrodynamic clutch device has at least one pump wheel, connected to a drive by way of a clutch housing, and a turbine wheel, connected to a takeoff, to form a hydrodynamic circuit. The device also has a bridging clutch with at least one piston, which can shift between a released position and an engaged position, and at least one friction surface acting between this piston and an adjacent support to connect the drive to the takeoff. When the piston is in the released position, the bridging clutch allows the hydrodynamic circuit to be used to transmit at least most of the torque between the drive and takeoff, whereas, when the piston is in the engaged position, the bridging clutch produces a bypass around the hydrodynamic circuit for the transmission of torque. The barrier clutch cooperates with at least one pressure barrier installed between the hydrodynamic circuit and the pressure space.

  • Patent number: 7392889
    Abstract: A hydrodynamic clutch device includes a clutch housing connected to a drive, a pump wheel connected to the clutch housing, and a turbine wheel connected to a takeoff, the turbine wheel and the pump wheel forming a hydrodynamic circuit. A bridging clutch which is essentially surrounded by the hydrodynamic circuit includes a piston and a friction surface which can be acted on by the piston to connect the drive to the takeoff independently of the hydrodynamic circuit, the piston having one surface facing a pressure space and an opposite surface facing the hydrodynamic circuit. A pressure circuit includes a first pressure medium line to supply the hydrodynamic circuit with clutch fluid and a second pressure medium line to supply the pressure space with clutch fluid. A seal at least reduces the exchange of fluid between the hydrodynamic circuit and the pressure space, and a throttle allows a defined exchange of fluid between the hydrodynamic circuit and the pressure space.

  • Patent number: 7216750
    Abstract: A clutch arrangement for a motor vehicle has a clutch housing that is filled with pumped medium in the form of fluid, a first friction element being rotatable in common with the clutch housing. Further, a second friction element is provided which is rotatable in common with a driven member and which can be brought into an operative connection with the at least one first friction element for producing a frictional interaction. At least one first friction element and at least one second friction element are each provided with a support component that can be provided for receiving at least one friction lining. The support components have support component segments which are arranged successively in circumferential direction and which are provided at a circumference-side terminating edge, respectively, with fluid delivery surfaces for generating a fluid circulation and are constructed in the form of friction lining segments to produce the frictional interaction with friction linings.

  • Patent number: 7152400
    Abstract: A hydrodynamic torque converter which has at least a hydrodynamic circuit including at least one pump wheel and one turbine wheel, wherein each of these wheels is provided with an outer shell to accept a set of vanes which form flow chambers, the inner edges of the vanes away from the outer shell being connected to an inner shell, which acts as part of an internal torus. At least the vanes of the turbine wheel have connecting elements both on the inner edges and on the outer edges, which connecting elements pass through openings in the shells to fasten the vanes to the shells, being provided for this purpose with a predetermined minimum overhang with respect to the edge of the associated vane, this minimum overhang making it possible for the connecting elements to be plastically deformed in such a way that they can grip the rear surfaces of the shells, i.e., the surfaces facing away from the vanes, and thus fasten the vanes to the shells.

  • Patent number: 6742637
    Abstract: A lock-up clutch for a hydrodynamic torque converter has at least one friction area on a first converter component, which area can be brought into working connection with at least one opposing friction area on a second converter component by an engaging movement of this converter component or which can be separated from this opposing friction area by a disengaging movement in the direction opposite that of the engaging movement. On at least one of the two converter components, a pump device acting in either the friction area or in the opposing friction area is present, which, as a result of its geometric shape, has the effect of building up a pressure gradient, by means of which a forced flow of hydraulic fluid through at least one predetermined section of the friction area and/or of the opposing friction area is produced.

  • Patent number: 6343671
    Abstract: To create an additional steering angle for a vehicle, an actuator having a microprocessor-controlled electric motor functioning as the drive and a gear driven by said electric motor, is used to apply to the wheels the additional steering angle at the vehicle axle. The gear is a known constant-pitch planetary rolling-contact threaded-spindle gear (constant-pitch PRCTS gear) (12), consisting of a spindle rod (16), a spindle nut (14) surrounding the former, and a number of interposed rollers or rolling elements (18) with a groove profile (19) matching the thread (17) of the spindle rod (16). The rollers or rolling elements (18) are run on a number of guide rings (20) and interposed bearings (20), and placed at a fixed predetermined distance relative to the spindle nut (14) and to one another. The spindle rod (16) concurrently functions as the axis of the electric motor and is placed inside an electric motor rotor (9′).
