A vehicle vibration reducing apparatus includes: an inertial mass body; a first engagement device that is switched between a state where a running power source engages with a damper of a power transmission device so as to enable power transmission and a state where the engagement is released; a second engagement device that is switched between a state where the power transmission device engages with the inertial mass body so as to enable power transmission in a power transmission pass different from that of the first engagement device and a state where the engagement is released; and a third engagement device that is switched between a state where the running power source engages with the inertial mass body so as to enable power transmission in a power transmission path different from those of the first engagement device and the second engagement device and a state where the engagement is released.

A torsional vibration damping arrangement for a drivetrain of a vehicle, having a carrier arrangement which is rotatable around an axis of rotation, a deflection mass movable in circumferential direction relative to the carrier arrangement, carrier arrangement and the deflection mass are coupled to be rotatable relative to one another via restoring elements arranged in circumferential direction that extend from the deflection mass in direction of the carrier arrangement. A restoring element is deformable around a force application point which is movable in radial direction under centrifugal force and which is associated with the restoring element. The movable force application point is acted upon by a preloading force acting radially in direction of the axis of rotation by a preloading spring. A main axis of the preloading spring and a main axis of the restoring element do not extend coaxially.

An unbalanced shaft for compensating for inertial forces and/or mass moments of inertia of an internal combustion engine (1), having an unbalanced portion (8), the center of mass of which extends eccentric to the axis of rotation (11) of the unbalanced shaft (6) for generating the shaft imbalance (7), a bearing portion (9) adjacent to the unbalanced portion, and a bearing race (10) joined thereto, the outer surface (13) of which serves as a race for the rolling elements of a roller bearing rotationally supporting the unbalanced shaft, and the inner surface (12) of which retracts radially relative to the outer circumscribed circle (14) of the unbalanced portion in a bearing circumference region running in the direction of the imbalance. In order to assemble the bearing race on the bearing portion, the following geometric relationships are provided: (i) d2>d1, (ii) e>½(d2−d1), (iii) e

A pot-shaped housing part, especially for a hub part of a hybrid drive. The housing part has a bottom and a wall extending axially away from the bottom, and an outer face of the wall extending at least approximately up to an outer face of the bottom, which outer face of the bottom faces away from a free edge of the wall. The wall and the bottom are configured as one piece. The outer face of the wall also has a projecting portion that projects axially beyond the outer face of the bottom and is produced from material of the wall.

Rolling element bores are provided in the outer circumferential portion of a disk-like main body. Each rolling element bore has an arcuate outer rim. Rollers each have a groove formed on the peripheral edge and extending along the entire circumference of the roller. The outer rim of each rolling element bore engages with the groove of the associated roller so that the roller is loosely fitted in the rolling element bore. Shafts are respectively formed on both sides of each roller. The shafts project from the center of the roller. An elastic ring is mounted on each shaft. Annular guide plates are respectively mounted on both sides of the disk-like main body so that the shafts of the rollers are supported by the guide plates.

An energy-storing flywheel assembly is provided with a flywheel having a vertically-oriented axis of rotation, a shaft connected to the flywheel, and a cageless ball thrust bearing rotatably supporting a lower end of the shaft. The flywheel may be formed from a stack of flywheel discs and is preferably relatively large-radiused and massive. The ball thrust bearing includes a stator having a set of three free-floating bearing balls contained within a cylindrical stator recess; a rotor rotatably mounted over the stator which likewise contains a set of three free-floating bearing balls within a cylindrical stator recess, and a single, middle bearing ball centrally disposed between and in mutual engagement with the three bearing balls of the stator and the three bearing balls of the rotor. In operation, the relatively massive flywheel is rotated at a peripheral speed that approaches but does not exceed the speed of sound to avoid fluid drag and the danger of explosive shattering.

A load coupling device for a power train including: a rotatable shaft; a first flange on a first end of the shaft, wherein the first flange is adapted to couple to a first rotating shaft of at a torque producing turbine or a torque driven electrical generator; a second flange on an opposite end of the shaft, wherein the shaft is adapted to couple to a second rotating shaft of the other of the turbine and the generator, and an annular ring extending radially outward from the first flange, wherein the mass of the annular ring is selected to shift a torsional natural frequency of the power train away from an operational condition of the power train. Trim masses may be added to make fine adjustments to the torsional natural frequency of the power train.

An active balancing system for rotating machinery is provided which is light weight, solid state and powered by radiant energy. One or more balance rings coupled to the rotating machinery each have balancing elements which are moved to a selected position by actuators whose operation is controlled according to measured vibration resulting from imbalance of the machinery. The actuators are powered by an electrical energy generating device, such as a photo cell or a photovoltaic element, which is coupled to the machinery and located across an air gap from a source of radiant energy such as an array of light emitting diodes.
