  • Patent number: 10591014
    Abstract: A multi-performance hysteretic rheological device. The invention concerns a mechanical device capable of providing restoring forces with non-linear hysteresis loops whose shapes can be adjusted depending on the specifications required by the application. The forces exerted on rigid sliding blocks on smooth bars are for example produced by the wire ropes composed of steel and shape-memory material wires. The device according to the invention can be used in very different applications including: vibration damper, hysteretic insulator, energy absorber, shock absorber, applications in which a specific rheological body with force-displacement characteristics of hysteretic type is required.

  • Patent number: 9574615
    Abstract: A centrifugal pendulum and a clutch disk with a pendulum flange provided thereon, rotational about an axis of rotation, and several pendulum weights distributed over the circumference and received on the pendulum flange in a pivotal fashion. In order to at least reduce noise development due to mass momentum of inertia acting here caused by the centrifugal pendulum, the pendulum flange is received on a rotational part, rotating on an axis of rotation, and a friction clutch is effectively arranged between the pendulum flange and said part.

  • Patent number: 8062135
    Abstract: A dual-mass flywheel has a first mass body and a second mass body which can rotate relative to one another by way of a damping device disposed between the first mass body and the second mass body. The damping device includes, running in the shape of an arc, at least one helical compression spring, which introduces spring force into the mass bodies via contact surfaces formed on the first mass body and the second mass body. The helical compression spring is guided in the radial direction by a wall formed by a mass body. At least one friction-reducing sliding component in the form of a wire cushion body is provided between the wall and the helical compression spring.

  • Patent number: 7445553
    Abstract: A damper disc assembly includes a drive plate rotatably connected to a driving power source, a driven plate connected to a driven side and being rotatable relative to the drive plate, a damping mechanism adjusted to absorb an impact caused between the drive plate and the driven plate in response to the relative rotation between the drive plate and the driven plate. The damping mechanism positioned at the driven plate. The damping mechanism includes a coil spring, and a torsion damper disposed in the coil spring. The torsion damper includes at least one guiding portion having a predetermined clearance relative to an inner side of the coil spring and a cushion portion integral with the at least one guiding portion inside the guiding portion.
