    摘要： A hydrodynamic torque converter is designed with a lock-up clutch which comprises a piston which can be extended in the axial direction and can be connected by at least one friction lining to the converter housing. The friction lining is designed with a multiplicity of depressions for the flow of hydraulic fluid, preferably oil, from the converter circuit, whereby the depressions extend between the radially outside edge and the radially inside edge of the friction lining in the circumferential direction at a specified angle, with a changing radial distance from the axis of rotation of the friction lining. Each depression changes its longitudinal direction between each inlet and outlet for the oil at least once, so that its radial component is oriented opposite to its orientation before the change.

    摘要： A hydrodynamic torque converter consists of a pump wheel driven by an internal combustion engine, a turbine wheel coupled to a drive shaft, and a stator which can be blocked in one direction of rotation. These wheels, together form a converter circuit filled with a hydraulic fluid, preferably oil, which interacts with a lock-up clutch. This lock-up clutch is located axially between the outside of the turbine wheel and the inside opposite it of the converter housing which forms the connection between the pump wheel and the internal combustion engine, and a piston which, like the converter housing, can also be driven preferably with some slip in relation to the corresponding friction lining, can be displaced axially and with the converter housing defines a chamber, which piston can be brought into contact by means of a first friction lining with a plate which is non-rotationally fastened to the turbine wheel, which plate is engaged for its part with its other side by means of a second friction lining with the converter housing. In the area of contact of the converter housing with the second friction lining there are channels for the flow of oil, which can carry the flow of oil on account of the pressure gradient between the turbine wheel and the chamber from radially outward to radially inward, while in the area of contact between the piston and the plate, a flow of oil into the chamber can at least be reduced.

    摘要： A hydrokinetic torque converter with a lock-up clutch which is located axially between the turbine wheel and the converter housing comprises a piston which, along with the converter housing, defines a chamber. The chamber is connected by means of at least one essentially radial flow guide to a longitudinal hole in the driven shaft. When oil which has been supplied by the converter circuit and has penetrated into the chamber in the vicinity of the friction lining flows through the chamber, the oil can be transported radially inward for discharge by means of the flow guide toward the converter axis, until it can be introduced into the driven shaft inside a ring-shaped zone surrounding the converter-axis which promotes the formation of a vortex when the converter housing is in rotation, and can then be transported via the longitudinal hole in the driven shaft to the reservoir.
