Abstract
A torsional damper device comprises two parts disposed to rotate relative to one another within defined limits of relative angualr movement. Such relative angular movement is resisted by elastic members each of which is disposed in a housing formed by holes in said parts. At least one bears in the circumferential direction and through the intermediary of a chock on the edge of the corresponding hole in one part. Opposite the other part, the chock has a recess such that on relative angular movement between the parts, this other part may become displaced in the circumferential direction beyond the point of contact of the chock on the corresponding edge of the hole in the first mentioned part.
Claims23
A torsional damper device comprising at least two coaxial parts disposed to rotate relative to one another within defined limits of relative angular movement, one of said parts having a transversely disposed flange and the other of said parts having a transversely disposed guide ring, circumferentially acting elastic means disposed between said parts for acting circumferentially on said parts so as to resist said relative angular movement between said parts, said elastic means including a plurality of individual elastic members, holes in said flange, holes in said guide ring, said holes in said flange and said guide ring together forming housings in which respective ones of said elastic members are disposed, a chock through which at least one of said elastic members bears on the edge of the respective hole in said guide ring, and a recess in said chock disposed in line with said flange, said recess defining means permitting angular movement of said flange relative to said guide ring in the circumferential direction beyond the point of contact of said chock with the edge of the corresponding hole in said guide ring.
A torsional damper device comprising at least two coaxial parts disposed to rotate relative to each other within defined limits of relative angular movement, one of said parts including a transversely disposed flange and the other of said parts including at least one transversely disposed guide ring, a plurality of holes in said flange, a corresponding plurality of holes in said guide ring generally aligned with said plurality of holes in said flange, said holes forming housings for receiving circumferentially acting elastic members for resisting relative angular movement between said parts, a chock mounted in and bearing on the edge of at least one of said holes in said guide ring and accommodating a different elastic member, said chock having a recess axially in line with said flange, said recess defining means permitting movement of said flange relative to said guide ring in the circumferential direction beyond a point of contact of said chock with the associated edge of the corresponding hole in said guide ring whereby said chock and said different elastic member modify the torsion damping characteristics of said torsional damper device.
