Abstract
A damper unit having at least two series-connected damper units arranged offset from each other in a radial direction, each including two damper parts that are coupled to each other by means of spring units and a speed-adaptive absorber which is at least indirectly coupled to the connection between the two dampers, wherein the speed-adaptive absorber is arranged between the spring units of both dampers in a radial direction.
Claims9
A damper unit comprising:
- a first damper including:
- first and second damper parts;
- and,
- a first spring engaged with the first and second damper parts;
- a second damper including:
- the second damper part;
- a third part separate from the first damper part;
- and,
- a second spring engaged with the second and third damper parts;
- and,
- a speed-adaptive absorber that is coupled between the first and second dampers, wherein:
- the second damper is radially inward of the first damper;
- the speed-adaptive absorber is directly connected to the second and third damper parts;
- the speed-adaptive absorber is displaceable with respect to the second and third damper parts;
- and,
- all of the speed-adaptive absorber is:
- axially located between the second and third damper parts;
- and
- axially aligned with the first and second dampers such that a line parallel to an axis of rotation for the damper unit passes through, in sequence, the second damper part, the speed-adaptive absorber, and the third damper part.
