    摘要: A hydrodynamic clutch includes a housing which can be brought into working connection with a drive; a hydrodynamic circuit formed by a pump wheel and a turbine wheel; a torsional vibration damper having a drive side transmission element, a takeoff side transmission element, and at least one energy storage group between the transmission elements; and a bridging clutch including first friction elements connected to the housing and second friction elements connected to the drive side transmission element. A first flow route extends from a first flow passage to the friction elements, and a second flow route extends from the hydrodynamic circuit to a second flow passage. A sealing arrangement cooperates with the drive side transmission element to separate the first flow route from the second flow route.

    摘要: A lockup clutch for a torque converter is provided with a friction lining. The friction lining is divided into a radially-outer-side friction lining and a radially-inner-side friction lining. μ-ν characteristics of the radially-outer-side friction lining have a positive gradient to inhibit occurrence of a shudder by a stick-slip which takes place. The radially-inner-side friction lining is equipped with a large coefficient of static friction to provide large torque capacity during a clutch engagement. The radially-outer-side friction lining is bonded on a side of a piston in said lockup clutch.

    摘要: 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.

    摘要: A hydrokinetic torque converter with a built-in bypass clutch is provided with an arrangement which regulates the cooling of the clutch at a rate dependent upon the slip between the coaxial driving and driven parts of the clutch, and hence upon the quantity of generated friction heat. The cooling unit for the driving and/or driven part of the clutch can employ, for example, one or more pumps; a supply of a substance which changes its aggregate state from liquid to gaseous or from solid to flowable in response to heating, and vice versa in response to cooling; one or more porous washers in the path for the flow of hydraulic fluid between the customary plenum chambers provided in the housing of the torque converter to move a piston of the driven part of the clutch into and from frictional engagement with the housing; and/or a system of recesses, grooves, channels and/or other passages serving to convey fluid between the chambers at a rate which is higher or highest when the clutch operates with maximum slip. Such rate can decrease to zero when the torque converter is idle or the clutch is fully engaged to operate without slip.

    摘要: 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.

    摘要: A friction element which can be used in the lockup clutch of a hydrokinetic torque converter and has a friction face engaging a complementary friction face when the clutch is at least partially engaged is provided with one or more channels which are machined, impressed or otherwise formed in its friction face to permit a fluid coolant to flow from a first compartment containing a pressurized fluid into a second compartment wherein the fluid pressure is lower. Each channel includes at least one fluid flow restricting portion which communicates with the first compartment and establishes a turbulent flow of fluid into a major portion of the respective channel. The major portion is designed to establish a laminar flow of fluid toward one or more outlets communicating with the second compartment. The reduction of pressure differential between the fluid in the first compartment and the fluid in the second compartment is effected by the respective fluid flow restricting portion or portions, either entirely or substantially entirely. This ensures a more satisfactory exchange of heat between the fluid in the major portion of each channel and the adjacent parts of the clutch.
