Problems solved by technology

[0003] However, in the process of clutch engagement and release, the instability of rotation occurs from time to time, so that the vibration frequency of the transmission parts is close to the natural frequency, thus causing vibration
At the same time, this instability may be transferred to the entire vehicle transmission system, causing unwanted noise interference to users, which is called howling in the industry.
[0004] At present, there is a lack of structure to prevent howling and reduce the impact of noise

Abstract

The invention discloses a torsional absorber, and belongs to the field of automobiles. The torsional absorber is arranged in the clutch hub of an automobile and is arranged side by side with a clutch plate group; the torsional absorber comprises a mass body, two friction plates, a retainer, a retainer baffle and an elastic collar, wherein the retainer is welded on the external surface of a clutchinner hub, the retainer baffle is arranged in the retainer and relatively fixed with the retainer; the retainer baffle supports the quality body, and is pressed by the elastic collar; and one friction plate is arranged between the quality body and the clutch hub, and the other friction plate is arranged between a mass block and the retainer baffle. The embodiment of the invention ensures the massbody and an assembly which is composed of the retainer and the retainer baffle to rotate together along the clutch inner hub, thereby automatically absorbing the vibration generated by a clutch system and relative parts; and the vibration of the automotive transmission is effectively reduced, the squeal generated by vibration is avoided.

Description

technical field [0001] The present invention relates to a shock absorber, and more particularly to a torsional shock absorber for absorbing vibration energy in an automatic transmission of an automobile. Background technique [0002] Usually, the automatic transmission of an automobile includes a clutch assembly, a shaft and a gear assembly, etc., through various ways of the shaft and gear assembly to select different combinations of clutches, so as to realize the change of the gear ratio of the transmission. [0003] However, in the process of clutch engagement and release, rotation instability occurs from time to time, so that the vibration frequency of the transmission parts is close to the natural frequency, thereby causing vibration. At the same time, this instability may be transferred to the entire vehicle transmission system, causing undesirable noise disturbance to users, which is called howling in the industry. [0004] At present, there is a lack of structures to...
