  • Patent number: 11353086
    Abstract: A torsional vibration damper that can reduce collision noise of an inertia body when a rotary member is stopped, and a control device therefore. In the torsional vibration damper, a rotary member is mounted on an output shaft of an engine such that none of rolling masses is situated within a predetermined angle range above a rotational center axis of the rotary member when the engine is stopped. Therefore, when the engine is stopped, the inertia body will not be supported by only one of the rolling masses situated within the predetermined angle range.

  • Patent number: 11162558
    Abstract: A torsional vibration damper in which collision noise resulting from collision of a rolling member against a rotary member is reduced. The torsional vibration damper comprises a restriction mechanism that establishes a restriction force in a direction to restrict the relative rotation between the rotary member and the inertia body, when the rolling member centrifugally pushed onto a raceway surface is pushed radially inwardly by the raceway surface toward a radially inner limit position of a guide section.

  • Patent number: 10968977
    Abstract: A torsional vibration damper whose vibration damping performance will not be reduced in a high speed range. In the torsional vibration damper, a planetary gear is oscillated within a first oscillating range when a torsional torque is smaller than a reference torque, and within a second oscillating range when the torsional torque is greater than the reference torque. Each backlash between the pinion gear and at least one of a sun gear and a ring gear within the second oscillating range is individually wider than each backlash between the pinion gear and the sun gear and each backlash between the pinion gear and the ring gear within the first oscillating range.

  • Patent number: 10962085
    Abstract: A torsional vibration damper includes a planetary rotary unit and an elastic body that couples two rotary elements of three rotary elements so that the two rotary elements can rotate relatively to each other. The torsional vibration damper includes a shaft supporting member by which a rotation center axis of at least any one rotary element of the two rotary elements and a rotation center axis of the rotary element other than the planetary rotary unit and the two rotary elements are held on the same axis. The shaft supporting member has a holding section that is disposed in a position between fellow planetary rotary elements and not making contact with the planetary rotary elements and that fits with and thereby suppresses movement of the rotary element other than the planetary rotary unit and the two rotary elements in the axial direction.

  • Patent number: 10830308
    Abstract: A torsional vibration damping device that prevents an increase in an inertial torque due to resonance without reducing a mass of an inertial mass member. A torque of an engine is delivered to a first rotary element of a planetary unit. The torsional vibration damping device damps pulsation of the torque of the engine to be delivered to the transmission by an inertial torque generated by a rotation of the third rotary element resulting from a relative rotation between the first rotary element and the second rotary element caused by the pulsation of the engine torque. The torsional vibration damping device comprises: a connection member rotated integrally with the first rotary element; an intermediate member rotated integrally with the second rotary element; an output member delivering torque to the transmission; a first elastic member connecting the connection member to the intermediate member; and a second elastic member connecting the intermediate member to the output member.

  • Patent number: 10788099
    Abstract: A torsional vibration damper in which a noise resulting from collision of an inertia body against a rotary member is reduced. An inertia body is arranged coaxially with the rotary member, and rolling members are interposed between the rotary member and the inertial body to transmit torque of the rotary member to the inertia body. A first clearance between an outer circumference of a rotary member and an inner circumference of the inertia body created when rolling members are centrifugally pushed onto raceway surfaces is identical to or narrower than a second clearance between one of the rolling members situated at a highest level and a bottom surface of a guide section.

  • Patent number: 10508603
    Abstract: An apparatus for controlling an internal combustion engine is provided. An engine includes a compression release mechanism and a fuel injection valve. The compression release mechanism variably controls the opening degree of a valve member, and thereby connects the combustion chamber of the engine with at least one of the intake passage and the exhaust passage in order to release in-cylinder pressure during at least the compression stroke. A controller controls the fuel injection valve to execute coasting with the fuel cut off in which the fuel is cut off under a predetermined condition, and while executing coasting with the fuel cut off, controls the compression release mechanism to increase the opening degree of the valve member of the compression release mechanism as the speed of the engine is higher.
