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

FIELD: transport engineering.

SUBSTANCE: friction shock absorber comprises a body (1) with a bottom (4) and a neck (3) formed by the walls (2) thereof. A wedge assembly (5) containing a pressure wedge (6) and spacer wedges (7) is located between the walls (2). A return and retaining apparatus (8) is located between the wedge assembly (5) and the bottom (4). The spacer wedges (7) are located in contact with the guiding elements (N). In the area from the ends (T) of the guiding elements (N) towards the bottom (4) of the body (1) at application of an external force to the pressure wedge (6), the contact of the spacer wedges (7) with the guiding elements (N) is supplemented with clearance areas (Z) between them. The length (a') of this section is equal to the size of the working stroke (a).

EFFECT: improved power characteristics, increased energy consumption and increased stability and reliability of the frictional shock absorber are achieved.
