  • Publication number: 20190203801
    Abstract: A rotating inertia mass damper of a damper device comprises a planetary gear including a driven member that has external teeth and that serves as a sun gear; a plurality of pinion gears; first and second input plate members that are configured to support the plurality of pinion gears in a rotatable manner and that serve as a carrier; and a ring gear that is engaged with the plurality of pinion gears and that serves as a mass body. The ring gear has two gear main bodies that are arranged along an axial direction of the planetary gear and that are coupled with each other. Internal teeth of the two gear main bodies are shifted to each other in a circumferential direction of the gear main bodies.

  • Publication number: 20180187743
    Abstract: An intermediate member includes first and second intermediate members. The first and the second intermediate members are provided with a spring supporting portion that extends along springs and supports the springs from an outer side. An expansion and contraction of the springs enables the intermediate member to be movable in a circumferential direction. Accordingly, sliding distances caused by the expansion and contraction of the first and the second springs become shorter, compared with a configuration where the first and the second spring are supported by the driven member or drive member from the outer side, thereby decreasing an energy loss (hysteresis) caused by the sliding. As a result, a vibration damping performance of the damper device can be improved.

  • Publication number: 20180156307
    Abstract: Six through holes are formed in pinion gear supporting portions of two input plate members working as a carrier that supports pinion gears of a rotary inertia mass damper. The two input plate members are opposed to each other in such a manner that the through holes are aligned with each other. The through holes support the pinion gear. The input plate members are coupled with each other by means of rivets passing through the through holes located on both sides of the through holes. This configuration ensures strength (rigidity) of the carrier, suppresses deformation of a planetary gear, and improves meshing accuracy of gears.

  • Publication number: 20180149232
    Abstract: An intermediate member is configured to include first and second intermediate members. Connecting portions that respectively extend outward from the first or the second intermediate plates are coupled with each other at two positions on the same circumference as pinion gears by two rivets (total six rivets at three connecting portions) as viewed in a central axis of the damper device. Such an arrangement enables spaces between the pinion gears to be used effectively, increases spaces for the first spring, the second spring and the inner spring and improves a vibration damping performance of a damper device.

  • Patent number: 8122988
    Abstract: A vehicular cooling device supporting apparatus has a radiator support lower 14 formed with a plurality of support-side connecting portions 32 and 34 for altering connecting positions to radiator support sides 16 and 18. This enables a layout position of a radiator main body 20 to be altered depending on size of an engine to use component parts in common. Placing the radiator main body 20 in a rearward position when the engine is small in size can suppresses damage to the radiator main body 20 upon collision of a vehicle at a low vehicle speed. In this case, it is suffice for the connecting positions of the radiator support lower 14 to the radiator support sides 16 and 18 to be altered in a vehicle fore and aft direction. Thus, the cooling device supporting apparatus can be constructed simply at the low cost with a minimum number of component parts.

  • Patent number: 7942223
    Abstract: A vehicular radiator supporting apparatus 10 has a pair of radiator support sides 16 and 18 connected to a radiator support upper 12 to be pivoted about a predetermined pivot axis O. To the pair of radiator support sides 16 and 18, a pair of abutting brackets 34 and 36 are integrally fixed at positions corresponding to a height of the bumper reinforcement 54, and they are connected to a pair of vehicle-body side brackets 38 and 40. When applied with a load exceeding a predetermined value and acting rearward of the vehicle, the pair of abutting brackets 34 and 36 are pivoted about the pivot axis O integrally with the pair of radiator support sides 16 and 18 to be displaced rearward of the vehicle. Thus, the vehicular radiator supporting apparatus 10 itself in addition to the radiator main body 20 is prevented from being damaged.
