Problems solved by technology

However, the device described in JP5051447B is configured to only connect the additional mass body to the mass body main body via the third elastic body, so it can only be used in conjunction with the dynamic damper determined by the elastic coefficient of the third elastic body and the inertia of the additional mass body. The vibration attenuation effect is exerted near the excitation frequency corresponding to the set frequency

Embodiment Construction

[0024] Below, refer to Figure 1 to Figure 14 Embodiments of the present invention will be described. The torque transmission device according to the embodiment of the present invention is applied to, for example, a torque converter of a vehicle having a lockup mechanism. figure 1 It is a cross-sectional view of a torque converter to which the torque transmission device according to the embodiment of the present invention is applied. In addition, below, for convenience, the front-rear direction is defined along the axis line CL0 as shown in the figure, and the configuration of each part will be described based on this definition.

[0025] Such as figure 1 As shown, the torque converter 10 has: a pump impeller 11 connected to an output shaft (crankshaft) of an engine not shown; and a turbine wheel 12 connected to an input shaft of a transmission not shown. The pump impeller 11 and the turbine wheel 12 are respectively provided so as to be rotatable about the axis CL0. The t...

Abstract

According to an aspect of the present invention, a torque transmission apparatus (100) for transmitting a torque from a first rotor (1) rotating around an axial line (CL0) to a second rotor (2), includes an intermediate member (3) disposed in a power transmission path (PA) between a first rotor (1) and second rotor (2); a first elastic member (4) interposed between the first rotor (1) and the intermediate member (3); a second elastic member (5) interposed between the intermediate member (3) and the second rotor (2); an inertial body (6) connected to the intermediate member (3) through a third elastic member (7); and an elastic member supporter (8) supporting the third elastic member (7) to be expandable and contractible. The elastic member supporter (8) supports the third elastic member (7) in a manner of applying an initial load to the third elastic member (3), in an initial state of the first and second rotors (1, 2) being non-rotating.

Description

[0001] This application claims priority based on Japanese application No. 2016-039247 for which it applied on March 1, 2016, and uses the content described in it by reference. technical field [0002] The invention relates to a torque transmission device with a vibration damping function. Background technique [0003] For example, in a torque converter with a lockup mechanism, a device having a vibration damping function is provided to prevent the torsional vibration generated by the rotational fluctuation of the engine when the lockup mechanism is in operation from being directly transmitted to the transmission. As such a device, in the device described in Japanese Patent No. 5051447 (JP5051447B), for example, a first elastic body, a mass body main body, and a second elastic body are connected in series and inserted between the lock-up clutch and the turbine. Furthermore, the additional mass body is connected to the mass body main body via the third elastic body to constitu...
