FRICTION SHOCK ABSORBER Russian patent published in 2018 - IPC F16F7/08 B61G11/14 

FIELD: machine engineering.

SUBSTANCE: shock absorber comprises a body (1) formed by its walls (3), a neck (2) and a bottom (4). On the bottom, there is a pre-pressed reciprocating device (5) with a friction unit (7) on its top. The friction unit consists of a pressure wedge (10) and spacer wedges (11) contacting with it. In the neck, there are guide plates (12) in contact with the spacer wedges and with the movable plates (13). The movable plates are placed in contact with the walls and provided with projections. The guide plates are mounted on the inner projections (26) and are provided with friction surfaces (F1 and F2). The friction surfaces are limited in zone from ends of guide plates from side of bottom towards the neck. The movable plates are provided with shanks (32). The width of shank ends is less than the width of movable plate ends at neck forepart.

EFFECT: improved reliability of friction shock-absorber operation.
