However, the C-shaped groove that comes with the side beam profile of the chassis is full-length on the side beam of the chassis (the full length means that the C-shaped groove is as long as the side beam profile of the chassis), and a gap is formed at the bottom of the side beam of the chassis. , which is unfavorable to the strength and rigidity of the car body; when the lower surface of the side beam of the underframe is welded with other parts, it is easy to open, which is easy to deform and even requires rework; and increases the invalid weight, which is not conducive to the lightweight of the car body

Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0037] Subway vehicle trailer structure such as figure 1 As shown, it mainly includes a car body body 1, a multi-functional lifting seat 2, and a trailer tooling 3. The multi-function lifting seat 2 is located at the two ends of the underframe side beams 11 on both sides below the underframe of the vehicle body 1, and is located on the longitudinal outside of the corbel 12 for installing the bogie. The multifunctional lift seat 2 can be arranged near the door opening 1a of the passenger compartment according to the spatial arrangement.
[0038] figure 2 It is a schematic diagram of the structure of the multifunctional lift seat. The multi-function car lift seat 2 is positioned at the underside of the underframe side beam 11, and the multi-function car lift seat 2 includes a trailer part 21, a car lift part 22 and a car tie part 23 three parts. Wherein th...

The invention discloses a trailer structure for a railway vehicle. The structure is characterized by comprising: a cantilever rib located on the inner side of a boundary beam of a chassis, wherein a first through hole is formed in the cantilever rib; a trailer part which is welded and fixed on the lower surface of the chassis boundary beam, wherein the trailer part comprises two stopping bosses which are arranged at intervals in the longitudinal direction, and the protruding direction of the stopping bosses faces downwards; and a trailer tool which comprises a mounting part and a traction arm fixed to the lower end of the mounting part, wherein a trailer boss is arranged on the upper surface of the traction arm, a dragging hole is further formed in the traction arm, and a second through hole is formed in the upper end of the mounting part. When the trailer tool is installed on the cantilever rib through a bolt, the bolt penetrates through the first through hole and the second through hole, the dragging hole of the traction arm is located in the outer side of the chassis boundary beam, and the trailer boss is located between the two stop bosses. A C-shaped groove does not need to be formed in the lower surface of the chassis boundary beam, the strength safety of a vehicle body can be improved, welding deformation rework is reduced, and further light weight is achieved.
Description
technical field [0001] The invention relates to a rail vehicle trailer structure and a trailer method, belonging to the technical field of rail vehicles, and relates to a rail vehicle structure, in particular to a subway vehicle. Background technique [0002] During the manufacturing process of the power-distributed rail passenger car or after the train is disassembled, the single car body itself does not have a complete power system, and cannot realize independent transfer transportation. At present, when the car body is transferred, external auxiliary traction devices, such as auxiliary power devices such as winches and locomotives, are usually used to drag the car body, so as to realize the purpose of transferring the car body along the rail. The operation mode of locomotives is limited to running on ordinary rails, and dragging at the coupler part usually requires adding a transitional coupler, or using the coupler part to transition the traction seat (such as the tracti...
