阅读说明：本技术 扭转减振器 (Torsional vibration damper ) 是由 薛勇 于 2018-03-20 设计创作，主要内容包括：一种扭转减振器(100,200,300),其中,初级质量件(20)和通道盖件(70)在外周缘固定到一起,在扭转减振器(100,200,300)的轴向上,支承环(90)的至少一部分设置在初级质量件(20)和法兰(40)之间,法兰(40)、膜片弹簧(60)和次级质量件(50)固定到一起,膜片弹簧(60)位于法兰(40)和次级质量件(50)之间并与通道盖件(70)弹性压抵。其中,支承环(90)包括调节支承环(92)和支承法兰(40)的固定支承环(91),调节支承环(92)的轴向截面为楔形,在磨损和/或膜片弹簧(60)塑性变形使得法兰(40)和初级质量件(20)之间的压力变小时,调节支承环(92)在离心力的作用下相对于固定支承环(91)朝向扭转减振器(100,200,300)的径向外侧移动,从而保持或增大初级质量件(20)和法兰(40)之间的轴向距离,维持膜片弹簧(60)的弹簧力大致恒定。(A torsional vibration damper (100, 200, 300) in which a primary mass member (20) and a passage cover member (70) are fixed together at an outer periphery, at least a portion of a support ring (90) is disposed between the primary mass member (20) and a flange (40) in an axial direction of the torsional vibration damper (100, 200, 300), the flange (40), a diaphragm spring (60) and a secondary mass member (50) are fixed together, and the diaphragm spring (60) is located between the flange (40) and the secondary mass member (50) and elastically pressed against the passage cover member (70). Wherein the support ring (90) comprises an adjusting support ring (92) and a fixed support ring (91) supporting the flange (40), the axial section of the adjusting support ring (92) is wedge-shaped, and the adjusting support ring (92) moves towards the radial outer side of the torsional vibration damper (100, 200, 300) relative to the fixed support ring (91) under the action of centrifugal force when the pressure between the flange (40) and the primary mass (20) is reduced due to wear and/or plastic deformation of the diaphragm spring (60), so that the axial distance between the primary mass (20) and the flange (40) is maintained or increased, and the spring force of the diaphragm spring (60) is maintained substantially constant.)

A torsional vibration damper comprising a primary mass member, a support ring, a flange, a diaphragm spring, a secondary mass member, and a passage cover, the primary mass member and the passage cover being fixed together at an outer periphery, at least a part of the support ring being disposed between the primary mass member and the flange in an axial direction of the torsional vibration damper, the flange, the diaphragm spring, and the secondary mass member being fixed together, the diaphragm spring being located between the flange and the secondary mass member and elastically pressed against the passage cover,

wherein the support ring includes an adjustment support ring and a fixed support ring supporting the flange, the adjustment support ring having a wedge-shaped axial cross section, the adjustment support ring moving toward a radially outer side of the torsional damper with respect to the fixed support ring under a centrifugal force when a pressure between the flange and the primary mass member becomes small due to wear and/or plastic deformation of the diaphragm spring, thereby maintaining a spring force of the diaphragm spring substantially constant.

The torsional vibration damper of claim 1, wherein the stationary support ring is a ring member having a generally L-shaped axial cross section, and the adjustment support ring comprises a plurality of arcuate ring segments.

The torsional vibration damper of claim 1, characterized in that in an axial cross section of the support ring, the contact surfaces of the fixed support ring and the adjustment support ring assume a straight line inclined with respect to a radial direction of the torsional vibration damper.

The torsional damper as claimed in claim 1, wherein an axial thickness of the adjustment support ring is formed to be smaller toward a radially outer side of the torsional damper.

The torsional vibration damper of claim 1, wherein the stationary support ring comprises: an axially extending portion extending in an axial direction and a circumferential direction of the torsional damper; and a radially extending portion extending in the radial and circumferential directions of the torsional damper, an axial thickness of the radially extending portion being larger toward the radially outer side.

The torsional vibration damper of claim 2, wherein the adjustment support ring is disposed between the fixed support ring and the primary mass, the torsional vibration damper further comprising a retaining ring fixed with the primary mass, the retaining ring configured to prevent a ring segment of the adjustment support ring from falling toward a radially inner side of the torsional vibration damper.

The torsional vibration damper of claim 2, characterized in that the adjustment support ring is disposed between the fixing support ring and the flange, the fixing support ring preventing the ring segments of the adjustment support ring from falling out towards the radially inner side of the torsional vibration damper.

The torsional vibration damper as claimed in any of claims 1 to 7, characterized in that the adjustment support ring is made of plastic.

The torsional vibration damper of any of claims 1 to 7, further comprising a friction ring through which an outer peripheral portion of the diaphragm spring is pressed against the channel cover.

The torsional vibration damper of any of claims 1 to 7, wherein the torsional vibration damper is a dual mass flywheel or a dual clutch damper.
