Problems solved by technology

[0013] However, the conventional torsional vibration damping device sets the same torsional characteristics during acceleration and deceleration. Therefore, when the torsional rigidity is increased, the torsional resonance of the drive transmission system can be damped in the low rotation range during acceleration. However, Torsional vibrations may not be sufficiently damped during deceleration

Abstract

A torsional vibration attenuation device capable of increasing the torsion angle between an intermediate rotating member and a driven side rotating member when the driven side rotating member is returned to a neutral position from a state of being twisted to the negative side relative to the driving side rotating member, The third elastic member can be greatly elastically deformed to prevent the decrease in attenuation performance. A return spring (36) is provided on the disc (12). The return spring (36) is located on the hub liner (11) relative to the disc (12, 12, 13) When twisted to the negative side, it comes into contact with the sub-plate (16) and bends between the sub-plate (16) and the circular plate (12), thereby facing the positive side end (25a) of the spring receiving window (25) ) and the bending part (27A) exerts force on the sub-plate (16) in the direction in which the gap increases.

Description

technical field [0001] The present invention relates to a torsional vibration damping device, and more particularly, to a torsional vibration damping device that is mounted on a vehicle and is capable of adjusting the torsional characteristics when the driven side rotating member is twisted to the positive side and the torsional characteristic when it is twisted to the negative side relative to the driving side rotating member. Different torsional vibration damping devices. Background technique [0002] Conventionally, there are known torsional vibration damping devices that couple a driving source such as an internal combustion engine or an electric motor to wheels to transmit torque from the driving source and absorb torsional vibration between the driving source and a drive transmission system having a transmission gear set. [0003] Generally, vibrations of a vehicle include noise during idling, noise during acceleration and deceleration, and tipping / receiving vibration ...
