A drive assembly for a motor vehicle clutch is provided. The drive assembly includes a subassembly includes at least one clutch facing and at least one support segment supporting the at least one clutch facing, the at least one support segment including an outer radial portion fixed to the at least one clutch facing and an inner radial portion extending radially inward from the outer radial portion; an extender connected to the inner radial portion of the at least one support segment; and a cover plate, the extender connecting the subassembly to the cover plate. A method of forming a drive assembly and a method of forming a plurality of drive assemblies are also provided.

A drive transmission device includes: a first rotating member that rotates with driving power received from a driving source, a second rotating member that rotates with driving power from the first rotating member, and a driving-side engagement member and a driven-side engagement member for transmitting the driving power of the first rotating member to the second rotating member, wherein the driving-side engagement member and the driven-side engagement member engage with each other in a state in which the first rotating member is rotating whereby a power applying portion and a power receiving portion engage with each other while resisting against a second biasing power.

A device for vibration reduction in a hydraulic actuating system has a housing in which a pressure chamber is able to be disposed in fluid connection with the actuating system by way of at least one connection and bounded by a resilient membrane. The membrane has a pressure-loadable surface and a surface which is remote therefrom and provided with a profiling, by way of which the membrane when loaded with pressure can be supported on a fixed wall section of the housing and which has at least one web section comprising at least one web with a web foot, a web end adjacent to the wall section, and a defined web cross-section. The web is of asymmetrical construction with respect to a notional plane extending normal to the pressure-loadable surface through the web foot and perpendicularly to the web cross-section.

A damping mechanism configured for use with a coupling of a power transmission assembly is provided including a cylindrical body having a first end and a second opposite end. The first end is configured for attachment to a first component of a power transmission assembly. A groove is formed in an exterior surface of the cylindrical body adjacent the second end. A cylindrical ring generally complementary to the groove is positioned partially within the groove such that a void exists between an inner surface of the cylindrical ring and the cylindrical body within the groove. A viscous material is arranged within the void such that non-concentric movement of the cylindrical ring relative to the cylindrical body causes displacement of the viscous material.

A turbo-compressor including a variable vane that adjusts the flow rate of a fluid, a drive shaft that is connected to the variable vane and is rotated to drive the variable vane, a motor that rotationally drives the drive shaft, and a coupling that couples the drive shaft with an output shaft of the motor. Between the drive shaft and output shaft and the coupling, a vibration isolation means is arranged to connect the drive shaft and output shaft to each other so that they rotate together and allow the drive shaft and output shaft to move in a vibration direction.

A power take off includes a housing, an input mechanism that is supported in the housing and is adapted to be rotatably driven by a source of rotational energy, and an output mechanism that is supported in the housing and is rotatably driven by the input mechanism, the output mechanism being adapted to rotatably drive a rotatably driven accessory. The power take off further includes a two piece damping assembly that minimizes the transmission of torque transients from the input mechanism to the output mechanism. The two piece damping assembly may be an input cluster gear assembly that includes a first gear portion and a second gear portion that are supported for rotational movement relative to one another. The two piece damping assembly may also be part of a clutch assembly for selectively the output mechanism to be rotatably driven by the input mechanism.

The present invention relates to an elastic junction device for the dynamic connection, in a rolling mill, between the motor side and the head of an adapter or between the adapter and one or more rolling rolls. The junction device comprises a central body which can be connected to an end of said flange so that it can rotate integrally therewith, said device comprising two skids through a connecting pin so that said block rotates integrally with said flange, said skids being mechanically couplable to said adapter to allow the rotation thereof upon the rotation of said flange and vice versa. The junction device comprises at least a first damper element and at least a second damper element housed in the block and which act on opposite parts of the connecting pin so as to absorb the axial tensions which are transmitted along the adapter as a result of the stresses caused by rolling.

A pulley structure includes: a cylindrical outer rotation body; an inner rotation body; and a torsion coil spring. The torsion coil spring includes: one end region which is in contact with one rotation body; the other end region which is in contact with the other rotation body; and a middle region. The other rotation body includes: a first contact surface; a facing surface; an inclined surface; and a second contact surface. The facing surface includes a constraining surface connected to the inclined surface. The constraining surface is configured to be capable of constraining the other end region of the torsion coil spring before press fitting so as to prevent a displacement of an axis of the torsion coil spring before the press fitting with respect to an axis of the other rotation body.
