Abstract

The present invention relates to a transmission input shaft damper (ISD), which may include an inertial body assembly relatively rotatably mounted on the input shaft of the transmission; and a planetary gear set, the planetary gear set mounted on the input shaft to receive and increase the rotational force of the input shaft and output the increased rotational force to the inertial body assembly.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0112030 filed on Oct. 31, 2011, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to an input shaft damper of a transmission, and more particularly to a technique for reducing rattle noise of a transmission by imparting additional inertia to the input shaft of the transmission to avoid resonance in a specific RPM region. Background technique [0004] As described in the following literature, the resonances that cause rattling noises in transmissions that do not use a dual mass flywheel (DMF) at a particular RPM band can be effectively avoided by including an input shaft damper (ISD), which damps The transmission is configured to mount the inertia plate on the input shaft of the transmission. [0005] However, in order for the ISD to obtain a suitable effec...
