Abstract: A vehicle including a combustion engine, a belt alternator starter, and a decouplable accessory power take-off for auxiliary units, wherein the accessory power take-off includes, as auxiliary units, at least an air-conditioning compressor and an electric motor as belt alternator starter that is usable as a motor and as a generator, wherein a coupling and a decoupling of the accessory power take-off occurs by means of a form-fitting clutch, and wherein at a standstill of the combustion engine during a short stop phase, a stationary air-conditioning operation occurs by means of a reverse rotation of the auxiliary units, and wherein a starting of the combustion engine after the short stop phase occurs by means of a reversal of the direction of rotation of the electric motor.

Abstract: A decoupler for damping torque transmission irregularities between a vehicle drive shaft and a belt pulley for driving vehicle auxiliary components. The decoupler includes first and second ramp rings for transmitting torque delivered by the drive shaft to the belt pulley. A spring arrangement provides for axial engagement of the ramp rings. The ramp rings have respective sloped push and pull ramps directed toward the adjacent ramp ring so that in a coasting mode of the vehicle the ramp rings rotate relative to each other and in a vehicle drive mode the ramp rings are drawn toward one another. The decoupler includes a pulley damper for damping torque transmission irregularities to reduce noise emission.

Abstract: A belt pulley damper for attenuating torsional vibrations of a drive shaft and includes a belt pulley for driving a pull mechanism, particularly a pulling belt. A torsional vibration damper, particularly a decoupler for torsional vibrations is connected with a drive flange and includes a driven disk movable circumferentially relative to the drive flange, and a driven disk is axially movable relative to a belt pulley. The belt pulley and the driven disk include axially-opposed teeth. The belt pulley teeth and the driven disk teeth can be engaged below a threshold pull force occurring during drive operation, and can be disengaged above the threshold pull force. In that manner, undesired torsional vibrations can be avoided by a free-wheel device without substantially increasing noise.

Abstract: A coupling system including at least two sub-units, one of which is pre-assembled on the engine side of a motor vehicle drive train, namely on the output shaft of the engine, and the other sub-unit is pre-assembled on the transmission side of the drive train. The pre-assembled sub-units each include respective interengaging teeth to provide a positive drive connection, and the teeth are biased toward each other to reduce circumferential play and thereby reduce noise that would be generated during operation of the drive train.

Abstract: A torsional-vibration damper rotatably supported for translating torque between a prime mover and the input of a transmission that includes a primary element operatively connected for rotation with the power take off of a prime mover and a secondary element operatively connected for rotation with the input to a transmission. A spring mechanism is operatively disposed between the primary element and the secondary element that is adapted to operatively couple the primary element to the secondary element in a damped torque translational relationship. The torsional-vibration damper also includes a friction device having a plurality of friction blocks that are each operatively supported between the primary element and the secondary element such that the friction blocks provide frictional contact between the primary element and the secondary element.

Abstract: A torsional-vibration damper includes a primary element operatively connected for rotation with a prime mover and a secondary element operatively connected with the input to a transmission. A spring mechanism is operatively disposed between and adapted to control the primary element and the secondary element in damped torque translational relationship. The torsional-vibration damper also includes a friction device having a plurality of fiction blocks that frictionally join the primary element with the secondary element. The secondary element includes an output-side member having a first axial ridge and a drive-side member having a second axial ridge. The output-side member and the drive-side member operatively encompass the primary element and the first axial ridge overlaps the second axial ridge. The first and the second axial ridges thereby cooperate to provide a double layer of radial support for the spring mechanism.

Abstract: The invention concerns a vibration damping device (2). This includes at least two elements—a primary element (3.1) and a secondary element (3.2), which are limited in movement in relation to each other. The primary element (3.1) and the secondary element (3.2) can be coupled together using a spring coupling. The means to implement spring coupling include at least one spring device (4.1, 4.N). Based on the invention, there is at least one adjustable clutch device (15, 15′), including at least two elements (16, 17; 16′, 17′) rubbing against each other, which bring primary and secondary elements (3.1, 3.2) into friction contact. In addition, there is a power generator or force producing device (39) to produce a controllable friction contact for the elements rubbing against each other (16, 17; 16′, 17′).

Abstract: A process for the cationically initiated preparation of oxymethylene copolymers in which, after the polymerization and after comminution of the crude polymer in a grinding assembly a portion of the deactivation suspension comprising the ground crude polymer is removed downstream of the grinding assembly and fed back to the process upstream of the grinding assembly. The return procedure predominantly reduces the proportion of oversize while the proportion of undersize rises only insignificantly. The treated crude polymer also has a lower proportion of unstable chain ends.
