Torsional vibration damper
View Patent ↗A torsional vibration damper with a damper component and a damper flange part limitedly rotatable within a circumferential clearance with respect to the damper component contrary to the effect of energy accumulator elements. The damper component is formed as a guide shell radially outside and surrounds the radial outmost circumferential section of the energy accumulator elements. The damper flange part comprises circumferentially disposed compression elements. The energy accumulator elements are circumferentially arranged in-between the compression elements. Cutouts formed in the guide shell and the compression elements engage radially into the cutouts whilst facilitating circumferential clearance.
1. A torsional vibration damper, comprising:
a damper component formed as a guide shell;
energy accumulator elements;
a damper hub; and,
a damper flange part:
fixed on the damper hub at a point radially inward of the energy accumulator elements;
limitedly rotatable within a circumferential clearance with respect to the damper component contrary to the effect of the energy accumulator elements; and
including circumferentially disposed compression elements, wherein:
the guide shell surrounds respective radial outmost circumferential sections of the energy accumulator elements;
the energy accumulator elements are circumferentially arranged between the plurality of compression elements;
the compression elements are radially disposed into respective cutouts formed in the guide shell; and,
respective circumferential extents of the respective cutouts are greater than respective circumferential extents of portions of the compression elements disposed in the respective cutouts.
2. The torsional vibration damper according to claim 1 , wherein a compression element includes a first guide element formed on a radially outward portion of the compression element, the first guide element radially supporting a first adjacent energy accumulator element and over-stretching the first adjacent energy accumulator element on a circumferential side, the first adjacent energy accumulator element engaging the first guide element in a respective cutout.
3. The torsional vibration damper according to claim 2 , wherein the compression element forms a second guide element that stretches over a second adjacent energy accumulator element on a circumferential side and radially outside.
4. The torsional vibration damper according to claim 3 , wherein the first guide element and the second guide element are similar in shape.
5. The torsional vibration damper according to claim 1 , wherein the damper component is formed as an input damper part for the transmission of torque through the action of the energy accumulator elements on the damper flange part formed as an output damper part or an intermediate damper part.
