A system of a side skirt for a car of a multi-car vehicle and a side skirt support, the side skirt configured to cover a space below the underframe of the car from a side, and having a coupler side edge that forms a side of the side skirt and arranged next to a coupler head of the car, the side skirt support suitable to attach the side skirt to the underframe of the car, the side skirt support having a bar with a first joint suitable to be attached to the underframe to allow rotation relative to the underframe, the bar being attached to a part of the side skirt via a second joint that allows part of the side skirt to rotate relative to the bar, the side skirt support having a rotation controller that limits the rotation that the part of the side skirt attached to the bar can perform relative to the bar, whereby the part attached to the bar can rotate into an end position, but cannot rotate beyond that end position.

A rail vehicle includes a coupling disposed centrally in a front region of the rail vehicle. The coupling is mounted in a transversely extended crossmember, so that forces acting on the coupling are introduced through the crossmember into abutments which are supported on a front side of a car body of the rail vehicle. The crossmember is connected through at least one elastic energy absorption configuration to one of the abutments.

A vehicle coupling assembly includes a bearing bracket, a rod, a pin and an abutment element. The bearing bracket includes compressible elements, a connection member intermediate the compressible elements, and a rear plate rearward of the connection member. The rod has an end wall, a first side of which is adjacent to one of the compressible elements. The pin extends through the compressible elements, a connection member hole defined in the bearing bracket, and an end wall hole of the rod. A pin support surface at a first pin end faces a first side of the connection member, one of the compressible elements being between the pin support surface and the second side of the connection member. The abutment element is at a second pin end, and abuts a second side of the end wall of the rod.

The present invention relates to a holder for mounting a second part on a main structure between car body ends of a rail vehicle, comprising —a first holding structure having a first contact surface, the first holding structure being configured to be attached to a main structure; —a second holding structure having a second contact surface, the second holding structure being configured to be attached to a second part, and the second holding structure further being arranged to be mounted on the first holding structure with one of the first and second contact surfaces resting on the other; —a fastening device for fastening the second holding structure to the first holding structure to form a mounted state, the first and second contact surfaces being pressed against each other in the mounted state, and wherein the first and second contact surfaces in the mounted state each extend at a first angle in relation to a horizontal axis, said first angle (α) being more than 1 degree and less than 30 degrees, and wherein the fastening device (53) extends in a direction parallel to or coinciding with the horizontal axis (A).

The application relates to a crash system for the head module of a rail vehicle, said head module being detachably fixed to the front face of a subsequent railcar unit without additional underframe. The crash system has a crash conduction element that carries a crash box at its front end and the back end of which is fixed to the underframe support of the subsequent railcar unit. In the event of a crash, crash forces are thus absorbed by the underframe of the subsequent railcar unit.

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).
