An assembly for increasing the load-bearing capacity of a structural component of a rail vehicle, in particular the tensile strength and the compressive strength. The structural component has a first connection point and a second connection point. A tensile force acting on the first connection point or a compressive force acting on the first connection point is transmitted to the second connection point. A first load path which is designed to transmit the compressive force is formed between the first connection point and the second connection point, and a second load path which is designed to transmit the tensile force is formed between the first connection point and the second connection point. The first load path and the second load path have different compressive strengths, thus achieving a division of the force transmission by the different compressive strengths.

The invention relates to a rail vehicle having a car body comprising an upper level and a lower level separated by an intermediate floor. The intermediate floor comprises at least two intermediate floor elements, the intermediate floor elements being arranged one behind the other in the longitudinal direction of the rail vehicle. A dilation profile is disposed between a first and second intermediate floor element.

A modern scenic passenger railcar system is disclosed. The railcar system incorporates design and safety features of modern freightcars and modern passenger scenic railway cars. The railcar system incorporates a center beam with a square cross section as well as specialized crash posts with its frame. This results in enhanced safety and crashworthiness. The railcar system also incorporates cross members for absorbing and distributing shock and mechanical stress on the railcar system during use, by withstanding torsion and shear forces on the frame. This results in improved mechanical integrity of the frame and the railcar system overall.

A connecting hanger bolt according to an aspect of the present invention is a hanger bolt which is inserted into a hanging groove rail having an opening narrower than the outer diameter of a bolt head and extending in a hanging groove rail longitudinal direction and from which a device is hangable. The connecting hanger bolt includes: a plurality of bolts which move in the hanging groove rail longitudinal direction in the hanging groove rail and whose shaft portions pass through the opening; and a connecting member which connects the plurality of bolts to each other, and keeps an interval in the hanging groove rail longitudinal direction between the plurality of bolts adjacent to each other.

A double skin structure of a railcar bodyshell includes: a harmonica type structural portion in which a closed space is quadrangular when viewed from a car longitudinal direction; and a truss type structural portion which is located adjacent to the harmonica type structural portion and in which a closed space is triangular when viewed from the car longitudinal direction. A thickness reduced portion is formed in at least one of a region between a car width direction middle portion of a roof bodyshell and a car body circumferential direction middle portion of a cantrail. The thickness reduced portion having a bodyshell thickness that is made small by arranging an inner wall of the thickness reduced portion at a car exterior side of the inner wall of a region adjacent to the region in which the thickness reduced portion is formed.

A rail vehicle body structure, comprising: a tubular corrugated plate; an annular beam and an underframe cross beam sleeved within the corrugated plate; and underframe side beams provided between the annular beam and the underframe cross beam. The two sides of the bottom of the corrugated plate are symmetrically provided with connection parts, and the underframe side beam is disposed on the outside of the connection part.

A floor section for an insulated railcar includes a floor plate and a composite section coupled to the floor plate. The composite section includes a plurality of composite beams aligned parallel to one another. Each composite beam of the plurality of composite beams includes an inner core and an outer material surrounding the inner core. The inner core includes an insulating material and is configured to support the outer material. An upper surface of each composite beam of the plurality of composite beams, which extends along a length of the composite beam, is coupled to an underside of the floor plate.

A corner connection is provided between support elements of a cableway cabin. The corner connection has a support element (1), designed as an elongated strut having a hollow end (2), and an angled connecting element (3) having a connecting piece (4). The connecting piece (4) is insertable into the hollow end (2) of the support element (1) in a form-fitting manner. An inner shape of the hollow end (2) and an outer shape of the connecting piece (4) have an angular design. At least two oppositely situated surfaces of the hollow end (2) and the connecting piece (4) are provided in a form-fitting manner in such a way that a gap (14, 14′) remains between the inner surface (10, 10′) of the hollow end (2) and the outer surface (9, 9′) of the connecting piece (4), wherein an adhesive material is provided in the gap (14, 14′).

A double-deck rail vehicle and a vehicle body thereof are provided. An underframe (11) of the vehicle body comprises a lower-layer underframe (111), end underframes (112, 115), sealing plates (114, 116), and side underframes (118, 119); wherein the lower-layer underframe is provided with an underframe middle beam (1111); the end underframe is fixedly connected to the underframe middle beam by means of reinforcement middle beams (113, 117); the sealing plate is fixedly connected between the end underframe and the lower-layer underframe; and the side underframe comprises side beams (1181, 1191) of the side underframe that are integrated, and the side underframe is fixedly connected to the end underframe by means of the side beams of the side underframe. The vehicle body supplements the reinforcement middle beams capable of increasing the connection strength between the end underframe and the lower-layer underframe, and uses the integrated side beams of the side underframe. Therefore, the structure strength, rigidity and compression-resistant performance of the vehicle body can be enhanced, so that the safety of the double-deck rail vehicle can be improved, and a problem that a related double-deck vehicle body does not satisfy the requirements of America strength standard can be solved.
