FRICTIONAL SHOCK ABSORBER Russian patent published in 2021 - IPC B60G11/14 F16F7/08 

FIELD: transport engineering.

SUBSTANCE: frictional shock absorber comprises a body (1) formed in the direction of the longitudinal axis (O1) by the walls (2) and in the direction of the transverse plane (P1) by the bottom (3) provided with long and short sides. A pressure wedge (4) and three spacer wedges (5, 5') in contact with each other along the surfaces (n1, n2) inclined to the longitudinal axis (O1) and to the transverse plane (P1) are located in the body (1), wherein a return and retaining apparatus (6) is located between said wedges and the bottom (3). Spacer wedges (5, 5') are located in contact with the walls (2) of the body (1) and placed in placement beds formed by these walls (2). The inclined surfaces (n1, n2) relative to the longitudinal axis (O1) and to the transverse plane (P1) are located at acute angles (α1, α2 and β1, β2). One of the angles (α2) between the longitudinal axis (O1) and the inclined surfaces (n2) of two adjacent spacer wedges (5) is greater than the angle (β2) between the inclined surfaces (n2) thereof and the transverse plane (P1).

EFFECT: increased reliability of the frictional shock absorber is achieved.
