Abstract: The invention relates to the field of transport mechanical engineering and concerns friction shock absorbers for vehicles. The object of the invention is to improve the operational life, performance and reliability of a friction shock absorber. The friction shock absorber comprises housing (1) with bottom (2) and with orifice (3) formed by walls (4), internal surfaces (fv) whereof form alternating working beds (V1) and connecting beds (V2), and further comprises friction assembly (5) consisting of pressure wedge (6) and stay wedges (7) in contact with same, said stay wedges being provided with friction surfaces (fp), while return-and-retaining device (8) is located between bottom (2) and friction assembly (5). In addition, the area (S1) of contact between friction surfaces (fp) of stay wedges (7) and internal surfaces (fv) of walls (4) of orifice (3) in working beds (V1) exceeds the corresponding area (S2) of contact in the connecting beds (V2).

Abstract: The present invention relates to the field of transport mechanical engineering. Object—improve performance and operational reliability of a friction shock absorber. The friction shock absorber (FIG. 2) comprises housing (1), whose walls form orifice (2), and bottom (4) that is in contact with return-and-retaining device (5) contacting a friction assembly that consists of the following elements fitted out with friction surfaces (f1-f10): supporting plate (10), pressure wedge (6), stay wedges (7), and reverse-U-shaped movable plates (9) fitted out with side shelves (14) that cover guide plates (8) and are located on supporting plate (10). Return-and-retaining device (5) is available between the guide plates. Additional return-and-retaining device (11) is available between the pressure wedge and the supporting plate.

Abstract: The present invention relates to the field of transport mechanical engineering. Object—improve performance and operational reliability of a friction shock absorber. It (FIG. 2) comprises housing (1) with internal protuberances, base (3), and orifice (6), wherein friction assembly (7) is situated that consists of pressure wedge (8) and stay wedges (9) contacting therewith, which wedges are in contact with guide plates (10) and movable plates (11) contacting therewith. The movable plates and stay wedges are in contact with pressure plate (12), between whereof and the base return-and-retaining device (14) is located contacting the carrying edge with its peak (15). Part (A) of the return-and-retaining device is situated between the guide plates resting against the housing's internal protuberances fitted out with recesses (21) that may run along the entire width of the guide plates. Width (B) of its Part (A) located between the recesses is bigger than the shortest distance (C) between the guide plates.

Abstract: The invention relates to the field of vehicle engineering and concerns friction shock absorbers for vehicles, primarily rolling stock. The aim of the invention is to increase the reliability and operating efficiency of a friction shock absorber. The present friction shock absorber (FIG. 3) comprises a housing (1), having a bottom (4) and a neck (2), which is formed by the walls (3) of the housing, said neck having disposed therein a return and retaining device (5) which can be compressed and which contacts with a friction assembly (7) consisting of a pressure wedge (10) and stay wedges (11) in contact therewith. In the neck (2) of the housing (1) there are arranged guide plates (12), which are in contact with the stay wedges (11) as well as with movable plates (13), the latter being in contact with the walls (3) of the housing (1) and being provided with protuberances (9), between which are disposed the guide plates (12), which are mounted on internal protuberances (20) in the housing (1).
