FRICTION SHOCK ABSORBER Russian patent published in 2021 - IPC B61G11/14 F16F7/08 

FIELD: transport engineering.

SUBSTANCE: friction shock absorber comprises case (1) with bottom (2) and neck (4) formed by walls (3). In neck (4), there is wedge assembly (5) containing pressure wedge (6) and spacer wedges (7). Between bottom (2) and wedge assembly (5) there is elastic device (8) formed by spacer damper (9) and retaining damper (10), between which separator (11) is located. Spacer wedges (7) are made with the possibility to ensure their contact with guide elements (N) in neck (4) and are equipped with support elements (E) facing bottom (2). Support elements (E) interact with spacer damper (9) when external forces are applied to wedge assembly (5). In the direction to the top of neck (4), starting from separator (11), pusher (12) is located without the possibility of transferring the entire load to retaining damper (10) from spacer wedges (7) when external forces are applied to wedge assembly (5).

EFFECT: increase in the stability and reliability of the friction shock absorber, as well as an increase in its energy consumption, is achieved.
