Abstract
A torque transmitting device comprising a torque input element (17a, 17b) and a torque output element (8) able to pivot about an axis (X) with respect to one another, at least one elastic leaf (22), rotationally coupled to the torque output element (8) or to the torque input element (17a, 17b) respectively, the elastic leaf (22) being able to be elastically and radially held torest on a supporting member (18) carried by the torque input element (17a, 17b) or the torque output element (8) respectively, the elastic leaf (22) being able to bend upon rotation of the torque input element (17a, 17b) with respect to the torque input element (8).
Claims20
A torque transmitting device, comprising:
- a torque input element (17a, 17b) and a torque output element (8) configured to pivot about an axis (X) with respect to one another;
- and
- at least two elastic leaves (22) rotationally coupled to the torque output element (8) or to the torque input element (17a, 17b), each of the at least two elastic leaves (22) configured to be elastically and radially held to rest on a supporting member (18) carried by the torque input element (17a, 17b) or the torque output element (8), each of the at least two elastic leaves (22) configured to bend upon rotation of the torque input element (17a, 17b) with respect to the torque output element (8);
- each of the at least two elastic leaves (22) comprising at least two stacked elastic blades (23a, 23b, 23c), the at least two stacked elastic blades (23a, 23b, 23c) and the supporting member (18) configured so that the supporting member (18) is able to rest on only one of the at least two stacked elastic blades (23a, 23b, 23c) during a first predetermined angular travel of the torque input element (17a, 17b) with respect to the torque output element (8), the supporting member (18) configured to simultaneously rest on all of at least two stacked elastic blades (23a, 23b, 23c) during a second predetermined angular travel of the torque input element (17a, 17b) with respect to the torque output element (8).
