Problems solved by technology

For example, while waiting at a traffic light a driver might shift the gear into neutral, causing the transmission to rattle.
If the rigidity of the drive transmission system is low, the torque transmitted to the tires is transmitted back from the tires as torque and a resulting lurching reaction causes excessive torque to be generated at the tires.
As a result, longitudinal vibrations occur that shake the vehicle excessively back and forth.
In the case of idling noises the problem lies in the zero torque region of the torsion characteristic of the clutch disk assembly.
Meanwhile, the second stage or high twisting angle region of the torsion characteristic has a relatively high torsional rigidity and high hysteresis torque.
The damper mechanism is configured to have a low hysteresis torque in the second stage of the torsion characteristic and does not allow a large friction mechanism of the second stage to operate wh...

Abstract

A damper mechanism is provided to suppress the enlargement of a prescribed angle in a damper mechanism. A clutch disk assembly 1 has an input rotary member 2, a spline hub 3, a damper section 4, a large friction mechanism 13, a friction suppressing mechanism, and an elastic member 104. The spline hub 3 is arranged to rotate relative to the input rotary member 2. The damper section 4 couples the input rotary member 2 and the spline hub 3 together rotationally. The large friction mechanism 13 can generate friction when the input rotary member 2 and the spline hub rotate relative to each other. The friction suppressing mechanism is a rotational gap thetaACp for preventing the large friction mechanism operating within a prescribed angular range. The elastic member 104 softens the impact between the members that touch against each other at the end of the prescribed angular range.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a damper mechanism. More specifically, the present invention relates more particularly to a damper mechanism for damping torsional vibrations in a power transmission system.[0003] 2. Background Information[0004] Clutch disk assemblies used in vehicles function as a clutch for engaging and disengaging a flywheel to facilitate the transfer of torque from an engine. Clutch disk assemblies also function as a damper mechanism for absorbing and damping torsional vibrations from the flywheel. In general, vehicle vibrations include idling-related noises such as rattling sounds, traveling-related noises such as rattling associated with acceleration and deceleration and muffled noises, and tip-in / tip-out or low frequency vibrations. The damper function of the clutch disk assembly is provided ideally to eliminate these noises and vibrations.[0005] Idling-related noises are rattling noises that emit from the transmission wh...
