Problems solved by technology

A idling state occurs during the filling of the gap, and no inertial torque is output to the transmission element (output member) via the rotating inertial mass damper. Therefore, it is difficult to satisfactorily attenuate the vibration in the above-mentioned torque converter.
Also, it is believed that the greater the backlash between the gear teeth, the longer the idling time required to fill the gap between the teeth of the intermeshing gears

Abstract

The rotational inertia mass damper (20) of a damper device has a planetary gear (21) including: a driven member (15) having external teeth (15t) and serving as a sun gear; a plurality of pinion gears(23); first and second input plate members (111, 112) for rotatably supporting the plurality of pinion gears (23) and serving as a carrier; and a ring gear (25) meshing with the plurality of pinion gears (23) and functioning as a mass body. The ring gear (25) has two gear bodies (250 (250a, 250b)) arranged in the direction of the axis of the planetary gear (21) and connected to each other. The internal teeth (25t (25ta, 25tb)) of the two gear bodies are offset from each other in the circumferential direction of the two gear bodies.

Description

technical field [0001] The present disclosure relates to shock absorbing devices. Background technique [0002] Conventionally, a torque converter including a lock-up clutch, a torsional vibration damper, and an inertial mass damper (transmission mechanism) having a planetary gear is known (for example, refer to Patent Document 1). The torsional vibration damper of the torque converter has: two cover plates (input members) connected to the lockup piston through a plurality of bearing journals; A sun gear that functions as a transmission element (output member); and a spring (elastic body) that transmits torque between the cover plate and the sun gear. In addition, the rotating inertial mass damper includes, in addition to the sun gear, a plurality of pinion gears (planetary gears) that are rotatably supported by a cover plate serving as a planetary carrier via bearing journals and mesh with the sun gear; and A ring gear that meshes with multiple pinions. In the torque con...
