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 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.
