Problems solved by technology

However, not only is it difficult to adjust the mass and spring constant of the damper device, but it is also difficult to eliminate the resonance point of the damper device in a wide range from the low speed range to the high speed range.
Therefore, in the case of using the existing damper device, it is difficult to suppress the torsional vibration of the engine in a wide range

Abstract

The invention relates to a damper device for inhibiting torsional vibration of an engine in a broad range. A damper device (11) is provided between the engine (12) and a transmission (13) and has a torque distribution mechanism (20) that is provided with a bracket C connected to the engine (12), a first gear ring (R1) connected to the engine (12) via a first elastic member (22), a sun gear S connected to the transmission (13), and a second gear ring (R2) connected to the transmission (13) via a second elastic member (24). The damper device (11) further has a first clutch (CL1) that is provided between the sun gear (S) and the transmission (13) that is switched between an engaged state of connecting the sun gear (S) and the transmission (13) and a released state of disconnecting the sun gear (S) from the transmission (13) and a second clutch (CL2) that is provided between the second gear ring (R2) and the transmission (13) and that is switched between an engaged state of connecting the second gear ring (R2) to the transmission (13) and a released state of disconnecting the second gear ring (R2) from the transmission.

Description

technical field [0001] The present invention relates to a damper device provided between an engine and a transmission. Background technique [0002] In order to reduce the torsional vibration transmitted from the engine to the transmission, a damper device is provided between the engine and the transmission. As such a damper device, a damper device including two flywheels connected via a spring has been proposed (see Patent Document 1). [0003] In this way, by connecting the two flywheels via the spring, torsional vibration of the engine can be suppressed. [0004] prior art literature [0005] Patent Literature [0006] Patent Document 1: International Publication WO2012 / 66680 [0007] On the other hand, the damper device is designed so that the resonance point (natural frequency) of the damper device can be eliminated from the normal range of the engine speed by adjusting the mass or spring constant of the components constituting the damper device. However, not only ...
