TORSIONAL OSCILLATION ABSORBING DEVICE FOR POWER TRANSMISSION SYSTEM IN CAR

摘要

PURPOSE:To reduce and absorb torque variation and prevent torsional oscillation by interlocking the support damper of the reaction torque actuated on a stator member with the drive and driven shafts of a planetary gear mechanism connected to the stator member. CONSTITUTION:A sun gear 10 is kept in stationary status by damper 13 through a stator shaft 11 and a lever 12. In this state, when one of gear trains 41 to 44 is selected and operated, the rotary torque transmitted to a clutch shaft 5 from an engine is transmitted to a drive wheel through an internal gear 7, planetary gear 8, carrier 9, input shaft 2, output shaft 3, driven gears 17 and 18, and differential gear 19. In this case, the reaction torque from the planetary gear 8 to the sun gear 10 is transmitted to and supported by the damper 13 through the stator shaft 11 and the lever 12. As a result, the variation of the reaction torque is absorbed by the damper and torsional oscillation can be prevented.
