Problems solved by technology

[0003] However, in a configuration in which the inertial disc is fixedly mounted to the input shaft, the inertial force of the input shaft itself remains high, resulting in an increase in the resistance torque of the input shaft at the time of gear shifting, which adversely affects the synchronicity of operation, and Provides rough shift operation
[0004] In addition, such inertial disks have space limitations for installation in existing transmission housings

Abstract

The present invention discloses a device for damping vibration of a transmission. The device for damping vibration of a rotary shaft of a transmission comprises an input shaft damper rotatably provided between a clutch and a transmission housing around an input shaft of the transmission; a centrifugal pendulum assembly rotatably connected to the input shaft damper to damp pulsation of the input shaft damper; and a bidirectional actuator provided between the input shaft damper and the clutch for bidirectionally applying force to the input shaft damper and the clutch so as to allow simultaneous bidirectional linear motions.

Description

technical field [0001] The present invention basically relates to a technique of variably providing inertial force to a rotary shaft of a manual transmission of a vehicle. More specifically, the present invention relates to a device for damping vibration of a rotating shaft of a transmission, which damps vibration of a rotating shaft of a transmission by providing an inertial force to an input shaft of the transmission to avoid resonance within a specific frequency range, Thereby reducing the vibration of the transmission and the noise generated due to the vibration. Background technique [0002] As disclosed in related art patent documents, by providing an inertial plate to a transmission, vibration and vibration noise of the transmission due to resonance in a specific frequency band can be avoided without using a dual mass flywheel (DMF) or the like. [0003] However, in a configuration in which the inertial disc is fixedly mounted to the input shaft, the inertial force o...
