Problems solved by technology

That is, the axial length of the rivet becomes longer, and the cost increases accordingly, and the axial length of the device as a whole becomes longer.
[0004] In addition, as described above, when the mass of the rotating body is large, the ratio of the rotating body as an inertial mass body to the mass of the entire torsional vibration reducing device decreases, so there is a possibility that the vibration damping performance is reduced. concerns, there is still room for improvement

Embodiment Construction

[0021] Hereinafter, the present invention will be specifically described with reference to the drawings. Vibrator type torsional vibration reducing device 1 according to the present invention, such as figure 1 As shown, it is built in the torque converter 2. Next, the structure of the torque converter 2 will be briefly described. The front cover 4 connected to the engine 3 and the pump casing 5 are integrated to form an integral casing of the torque converter 2 . The input shaft 6 of the speed change mechanism is arranged along the central axis of the housing. On the outer peripheral portion of the input shaft 6, a turbine hub 7 is integrally and rotatably provided. A turbine wheel 8 , a lock-up clutch 9 , and a vibrator-type torsional vibration reduction device 1 are connected to the turbine hub 7 .

[0022] The turbine impeller 8 is arranged to face the pump impeller 10 , and receives the oil flow from the turbine impeller 10 to rotate. In addition, the lock-up clutch 9...

Abstract

A pendulum torsional-vibration reducing device includes: a rotor having a plurality of through-holes formed in the rotor with predetermined intervals in a circumferential direction of the rotor; a rolling element disposed in the through-holes so as to carry out pendular movement; and a casing fixed to the rotor so as to cover the rolling element, wherein the casing includes fixing pieces in tightcontact with both side surfaces of the rotor so as to hold the rotor therebetween, and a thickness of the rotor at a position where the fixing pieces are in tight contact is thinner than a thickness of the rotor at a position where a rolling surface to which the rolling element is pushed by centrifugal force is formed.

Description

technical field [0001] The invention relates to a device for reducing torsional vibration through the reciprocating motion of a rotating body or the motion of a vibrator. Background technique [0002] JP 2016-011668 describes a torsional vibration reduction device built in a torque converter. The torsional vibration reducing device described in Japanese Patent Application Laid-Open No. 2016-011668 includes a rotating body and a rotating body, and the rotating body moves along a rotating surface formed on the rotating body while moving the vibrator to reduce torsional vibration of the rotating body. In addition, in the above-mentioned rotating body, the rotating body and the vibrator movement area of ​​the rotating body are sealed in a liquid-tight state by the casing so that the movement of the vibrator of the rotating body is not hindered by oil in the torque converter. In addition, the housing is composed of two shell members, and the rotor is covered by the first and sec...
