Abstract: The invention relates to a method for manufacturing a centrifugal pendulum (1) as well as a centrifugal pendulum (1) which is manufactured using said method and which comprises pendulum components (13, 14) made of sheet metal, i.e. a pendulum mass support (2) that is arranged about an axis of rotation (d), and pendulum masses (3) that are distributed about the circumference. In order to reduce tool costs and the cost per item, at least one punched blank (9) comprising at least two pendulum components (13, 14) is manufactured, whereupon the pendulum components (13, 14) are separated from one another.

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 hydraulic torque converter, particularly for use in a motor vehicle between the prime mover and the transmission of the power train, employs a combination of a bypass clutch with one or more torsional vibration dampers which brings about savings in space and/or in the number of parts. In addition, the torque converter can stand long periods of use and is less prone to wear, adverse influences of abruptly developing stresses and/or other undesirable influences than conventional torque converters. Furthermore, the improved torque converter employs or can employ a bypass clutch and/or one or more torsional vibration dampers simpler and less expensive than but superior to those in conventional torque converters.

Abstract: A method and an actuating arrangement for automatically actuating a component of a motor vehicle brake is actuated by an externally applied force and independently of an actuation of a brake pedal by the driver of the vehicle clutch actuation occurs at times when the speed of the vehicle is substantially zero, or when the vehicle rolls backward with the gearbox engaged in a forward gear, or when the vehicle rolls forward with the gearbox engaged in a reverse gear. Clutch wear and tear is thereby reduced. Additionally, the vehicle clutch can also be automatically actuated by an externally applied force, to engage or to disengage the clutch based upon predetermined operating parameters of components of the vehicle.

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.
