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).

The internal surfaces (fv) may be straight, while the values of angles (θ1) between adjacent internal surfaces (fv), which form working beds (V1), are lower than the values of angles (θ2) between adjacent internal surfaces (fv), which form the connecting beds (V2).

The thickness of walls (4) of the orifice (3) is variable with an increase in the direction from the working bed (V1) to the connecting bed (V2).

The contact between pressure wedge (6) and stay wedges (7) is provided along linked curved surfaces (fκ).

A segmented track for a Maglev vehicle includes a structural support portion and a Maglev portion fastened to the structural support portion. Each segment of the structural support portion is formed by fusing together three cast metal components. Neighboring ones of the structural support segments are joined together end-to-end by fused metal, and neighboring ones of the reaction rail segments are joined together end-to-end by fused metal. The positioning and joining of the successive segments is done in the field using on site jigs and machines.
