20090078522 | Hydrodynamic torque converter with coupling spring device for the piston - A hydrodynamic torque converter with a driving pump wheel and a drive turbine wheel that is placed in a housing in such a way that it can rotate is fixed to the drive shaft of a drive unit, and is connected to the housing with a converter bridging coupling that has a piston which remains fixed, with the help of a coupling spring mechanism, but which can be rotated in an axial direction. | 03-26-2009 |
20100210366 | TORSIONAL VIBRATION DAMPER - A torsional vibration damper with a friction device. The friction device is formed on at least one friction surface on two contra-rotationally and oppositely disposed disc parts that are in frictional contact with one another. In order to propose how to determine the initial stressing effect of the frictional action independently of external support of the disc parts, the frictional surfaces are pressurized against one another by means of at least one spring element. | 08-19-2010 |
20110165949 | TORSIONAL VIBRATION DAMPER - A torsional vibration damper, comprising at least two components which can be rotated counter to the resistance of at least one helical spring or bow spring precurved toward the rotational axis for compression of the at least one bow spring during a relative rotation among the components. The at least one bow spring is provided with support in the circumferential direction across the outside diameter thereof on a sliding shell. In order to reduce friction, the outside diameter of the at least one bow spring has a distance from the inside diameter of the sliding shell. | 07-07-2011 |
20110201433 | DEVICE FOR DAMPING VIBRATIONS - A device for damping vibrations comprising at least two coaxially arranged damper parts rotatable relative to each other to a limited extent in the circumferential direction, coupled by torque transmitting means and damping coupling means, which exhibit at least one energy accumulator unit, and forming the impingement areas for the energy accumulator units. At least one damper part forms a guide channel for the energy accumulator units. The individual impingement area on the damper part forming the guide channel for the energy accumulator units is formed by a stop element, connected in a torsion proof manner at least indirectly to the damper part and forms the abutment faces in the guide channel in the circumferential direction. The abutment face is capable of supporting the energy accumulator unit on both sides of the impingement area on the energy accumulator unit and is a part of the other damper part. | 08-18-2011 |
20120031226 | CENTRIFUGAL FORCE PENDULUM - A centrifugal force pendulum arranged on a rotatable pendulum flange, for example, in the drive train of a motor vehicle. Pendulum masses, which can be moved to a limited extent in the radial direction and circumferential direction during the deflection thereof, are provided at the sides of the pendulum flange, for example, mutually opposing each other. Said opposing pendulum masses are fastened to each other by a connecting element, forming a pendulum mass pair. A bearing is disposed on the connecting element. | 02-09-2012 |
20120255394 | CENTRIFUGAL PENDULUM MECHANISM - The invention relates to a centrifugal pendulum mechanism, having at least one pendulum mass support and at least one pendulum mass arranged thereon, which pendulum mass can be moved to a limited extent radially relative to the pendulum mass support by means of at least one rolling element inside raceways formed by recesses in the pendulum mass support and the pendulum mass and in the circumferential direction, the rolling element having guiding means formed in the gap between the individual pendulum mass and the pendulum mass support. The invention includes means for reducing the gap size between the pendulum mass and the pendulum mass support in an at least spatially limited manner are provided outside the raceways for the rolling element and outside the range of the intermediate space between the pendulum mass and the pendulum mass support that can be converted by the guiding means. | 10-11-2012 |
20130116079 | Transmission for operating an auxiliary assembly - A transmission for operating an auxiliary assembly in a drivetrain of a hybrid vehicle, includes a first sun gear rotatable about a main axis on a drive input side of the transmission, a first planet gear in engagement with the first sun gear on the drive input side of the transmission, a second planet gear on a drive output side of the transmission and mounted with the first planet gear on a common shaft, and a second sun gear in engagement with the second planet gear on the drive output side of the transmission, for coupling to the auxiliary assembly. The first planet gear is connected to the shaft by a first freewheel, which generates a rotationally conjoint connection when the first planet gear overruns in a first direction of rotation, and generates a freewheeling connection when the first planet gear overruns in a second, opposite direction of rotation. The shaft is mounted in a second freewheel in a planet carrier, which second freewheel permits a rotation of the shaft when the shaft rotates about its axis in the first direction of rotation and blocks a rotation of the shaft in the second, opposite direction of rotation. | 05-09-2013 |
20130233125 | TORSIONAL VIBRATION DAMPER - A torsional vibration damper for a drivetrain of a motor vehicle having a substantially discoidal centrifugal flange and a plurality of centrifugal pendulum-type absorbers. Each centrifugal pendulum-type absorber includes a first pendulum mass and a second pendulum mass. The first pendulum mass is arranged above a first surface of the pendulum flange, and the second pendulum mass is arranged above a second surface of the pendulum flange. The first pendulum mass and the second pendulum mass are firmly connected to each other by means of at least two spacing bolts in each case. The pendulum flange has a plurality of cutouts in which the spacing bolts are guided. A second spacing bolt of a first centrifugal pendulum-type absorber and a first spacing bolt of a second centrifugal pendulum-type absorber are guided in at least one first cutout. | 09-12-2013 |
20130239745 | CENTRIFUGAL PENDULUM MECHANISM - The invention relates to a centrifugal pendulum mechanism that includes a pendulum flange and pendulum masses which are fastened on both sides of the pendulum flange by means of a spacing bolt accommodated in a curved cutout of the pendulum flange to form a pair of pendulum masses, where the pair of pendulum masses is guided relative to the pendulum flange by means of the at least two rollers and can be pivoted restrictively because of a stop, where the rollers are accommodated in curved guide tracks in the pendulum masses and in complementary curved guide tracks in the pendulum flange and can be rolled, and at least two pairs of pendulum masses are arranged so as to be circumferentially adjacent to each other. | 09-19-2013 |
