Title:
TORQUE FLUCTUATION INHIBITION DEVICE AND POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2021071190
Kind Code:
A
Abstract:
To reduce hysteresis torque caused in conjunction with movement of a centrifugal element with a simple structure.SOLUTION: A torque fluctuation inhibition device 10 includes: a hub flange 2; an inertia ring 3; a centrifugal element 4; a needle roller 6; and a cam mechanism 5. The hub flange 2 has a housing part 21. The inertia ring 3 can rotate relative to the hub flange 2. The centrifugal element 4 is disposed within the housing part 21 in such a way so as to be movable in a radial direction and receives a centrifugal force. The needle roller 6 guides radial movement of the centrifugal element 4. The needle roller 6 is disposed between both circumferential end surfaces 4a, 4b of the centrifugal element 4 and wall surfaces 21a, 21b of the housing part 21 and can roll to move freely in the radial direction within a predetermined range. The cam mechanism 5 receives the centrifugal force acting on the centrifugal element 4 to convert the centrifugal force into a force acting in a circumferential direction that reduces a rotational phase difference between the hub housing 2 and the inertia ring 3.SELECTED DRAWING: Figure 3
