摘要： A car coupling system for a rail vehicle includes a draft sill, and a crash energy management system disposed within the draft sill. The crash energy management system includes a first end plate, a second end plate, and a central tube disposed between the first end plate and the second end plate. The central tube is configured to deform in response to a force exerted into the car coupling system that exceeds a predetermined force threshold. Deformation of the central tube attenuates at least a portion of the force.

摘要： 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).
