Abstract: 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.

Abstract: A torque-transmitting apparatus for motor vehicles includes a hydrokinetic torque converter with a housing connected to the driving shaft of an engine. The housing contains a pump and a turbine, the latter arranged to drive an input shaft of a power train. At least one damper is arranged in the power flow path between the turbine and a rotary output element of the apparatus. The damper has an input member constrained to rotate with the turbine and an output member connected to the rotary output element. The input member and the output member are rotatable relative to each other against the opposing forces of energy-storing devices arranged between the input member and the output member. The input member has a radially outer portion in form-locking engagement with the turbine.

Abstract: The rotary housing of a hydrokinetic torque converter, which can be utilized in the power train of a motor vehicle—for example, in conjunction with a continuously variable transmission—contains a torque monitoring device which is installed in such a way that it does not take up any, or any appreciable, additional space, especially in the axial direction of the housing. The torque monitoring device can serve to transmit torque between the lockup clutch and the output element of the torque converter. Additional features reside in the provision, configuration and manner of mounting of an auxiliary mass, and in the provision of a member for centering the piston of the lockup clutch in the housing as well as a member for centering the housing on the output element of a prime mover.

Abstract: The housing of a hydrokinetic torque converter in the power train between the engine and the transmission of a motor vehicle contains a lockup valve which can be engaged to transmit torque directly from the output element of the engine to the output member of the turbine in the housing. Engagement of the lockup clutch at a relatively low RPM of the engine and/or under certain other circumstances is prevented or minimized by the provision of one or more valves which are designed to establish or to at least partially seal one or more paths for direct flow of hydraulic fluid between two compartments forming part of a chamber in the housing of the torque converter and being disposed at opposite sides of the axially movable piston of the lockup clutch. The valve or valves can be designed to react in response to changing RPM of the housing of the torque converter, in response to changes of the temperature of hydraulic fluid in the housing and/or in response to changes of the viscosity of such fluid.

Abstract: The invention relates to a hydrodynamic torque converter including a turbine wheel arranged inside of a housing, a torque converter lockup clutch, an axially mounted piston, a torsional vibration damper and a hub. The turbine wheel and the piston are rotationally fixed to the input component of the damper. The input component is connected to the hub by means of a connection provided with a circumferential backlash. The output component of the damper is connected to the hub without circumferential backlash.

Abstract: A hydrokinetic torque converter in the power train between the engine and the wheels of a motor vehicle has a rotary engine-driven housing which is of one piece with a pump and contains a rotary turbine having a hub which drives the input shaft of a transmission. A lockup clutch can be engaged, either entirely or with slip, to transmit torque from the housing or from the pump to the hub of the turbine. Such clutch can employ flat or conical friction linings and/or friction surfaces, for example, a friction lining on the shell of the turbine and a friction surface on a wall of the housing. The shell of the turbine in the torque converter employing such clutch is movable axially to advance the friction lining into or from engagement with the friction surface. Alternatively, the lockup clutch can be installed in a torus which is defined by the turbine and the pump of the torque converter, and such clutch can be cooled by one or more streams of a hydraulic fluid.

Abstract: The invention relates to improvements in dampers which can be utilized in the power trains of motor vehicles to absorb torsional vibrations of the rotary output shaft of the engine and/or torsional vibrations of the rotary input element of a change-speed transmission normally receiving torque by way of a torque converter. One of the dampers is installed externally of the housing of the torque converter and, if used, another damper can be installed in the power flow between the piston of a lockup clutch in the housing of the torque converter and a turbine of the torque converter. The external damper can include an energy storing component and a friction generating component which latter is or can be sealed from the energy storing component.
