FRICTION ABSORBER DEVICE Russian patent published in 2017 - IPC B61G9/06 B61G9/10 F16F7/08 

FIELD: machine building.

SUBSTANCE: friction absorber device comprises a casing (1) with a bottom (3) and the neck (2) in which a friction assembly (4) consisting of a pressure element (11) and wedges (12) is located. Previously drawn in reverse retaining device ia licated on the bottom (3). Pushing member (11) is provided with a convex curved surface, and wedges (12) are provided with concave curved surfaces. Between the pressure element (11) and wedges (12) there are spacers (20) with a convex and concave curved surfaces. The concave curved surfaces of the spacer elements (20) are associated with the convex curved surface of the pressing element (11), and the convex curved surfaces of the spacer elements (20) are associated with the concave curved surfaces of wedges (12).

EFFECT: effectiveness of the friction absorber device by providing a variable angle of the device wedging during movement of its pressure element in the frictional node.
