一种扭转减振器
摘要：
本发明公开了一种扭转减振器，属于汽车领域。所述扭转减振器设置在汽车的离合器毂内，并与离合器片组轴向并排布置，所述扭转减振器包括质量体、两片摩擦片、保持架、保持架挡板及弹性挡圈，所述保持架焊接在所述离合器内毂的外表面上，所述保持架挡板安装在所述保持架内，并与所述保持架相对固定，所述保持架挡板支撑所述质量体，并且通过所述弹性挡圈压紧所述保持架挡板，所述质量体与所述离合器毂之间、以及所述质量块与所述保持架挡板之间分别设有所述摩擦片。本发明实施例使得质量体随着离合器内毂与保持架和保持架挡板组成的组件一起旋转，从而在需要时自动吸收离合器系统及其相关件产生的振动，有效降低了汽车传动系统的振动，防止因振动产生的啸叫。
摘要（英）：

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.
