Abstract
The utility model relates to a railway vehicle roof and side wall connecting structure which is formed by a roof edge beam , a roof curve beam, a roof plate, a roof lower edge beam and a side wall upper edge beam. The roof edge beam is fixedly connected with the roof lower edge beam and the side wall upper edge beam. The roof edge beam and the roof lower edge beam are respectively and fixedly connected with the roof curve beam. The roof plate is fixedly connected with the roof curve beam. The roof curve beam is formed integrally in a punched mode and the cross section of the roof curve beam is Z-shaped. The rood edge beam is molded in a roll compressing mode. The roof curve beam and the roof edge beam can be welded outside a visible area. Due to the fact that the cross section of the roof curve beam is Z-shaped and the roof curve beam is formed integrally in a punched mode to be connected with the roof edge beam, the roof plate and the roof lower edge beam, the railway vehicle roof and side wall connecting structure is capable of simplifying the circular-arc-shaped structure under the premise that roof strength and stiffness are satisfied, simplifying processing technique, improving production efficiency and improving appearance quality of the whole vehicle due to the fact that welding point is invisible in the visible area of the vehicle.
Description
Technical field
The utility model relates to a kind of stainless steel car body structure, and particularly a kind of guideway vehicle roof and side wall connecting structure belong to vehicle body of railway vehicle manufacturing technology field.
Background technology
Existing stainless steel car body is by roof, two side walls, the body structure that two headwalls and underframe surround, connection structure between roof and the side wall mainly is comprised of car roof side-beam, roof lower-edge beam, carline, roof hoard, side wall cantrail and framed side wallboard, car roof side-beam and roof hoard and carline are welded and fixed, roof lower-edge beam and car roof side-beam are welded and fixed, roof lower-edge beam and side wall cantrail are welded and fixed, framed side wallboard and side wall cantrail are welded and fixed, thereby roof and side wall are linked together.Wherein, what carline generally adopted is stretch bending process, by three plate splicing welding, complex process, the welding job amount is large, the weld easily produces welding deformation, and welding quality control is difficulty, and the intensity of connection structure, rigidity and load-carrying capacity are limited, in order to reach car body to the requirements at the higher level of strength and stiffness, need corresponding increase solder joint, this is just so that can obviously see solder joint in the viewing area of roof, and then the whole appearance effect of impact.
The utility model content
The utility model main purpose is to address the above problem and is not enough, provides a kind of technique simple, satisfies car body strength and rigidity requirement, and can improve guideway vehicle roof and the side wall connecting structure of roof presentation quality.
For achieving the above object, the technical solution of the utility model is:
A kind of guideway vehicle roof and side wall connecting structure, formed by car roof side-beam, carline, roof hoard, roof lower-edge beam and side wall cantrail, described car roof side-beam is captiveed joint with described roof lower-edge beam, side wall cantrail, described car roof side-beam is captiveed joint with described carline respectively with the roof lower-edge beam, described roof hoard is captiveed joint with described carline, described carline is that whole punch forming and its section are Yi shape, described car roof side-beam is roll-forming, and the position of weld of described carline and described car roof side-beam is outside the viewing area.
Further, between described side wall cantrail and described roof lower-edge beam, be provided with for the pad of regulating height of the carbody.
Further, adopt resistance spot welding to be welded and fixed between described carline and the described car roof side-beam.
Further, adopt resistance spot welding to be welded and fixed between described car roof side-beam, roof lower-edge beam, the described side wall cantrail.
Further, adopt resistance spot welding to be welded and fixed between described carline and the described roof hoard.
Further, adopt electric arc welding to fix between described roof lower-edge beam and the described carline.
Content to sum up, a kind of guideway vehicle roof described in the utility model and side wall connecting structure, having adopted section is Yi shape and whole stamping forming carline, and then be connected with car roof side-beam, roof hoard and roof lower-edge beam again, under the prerequisite that satisfies roof strength and rigidity, simplified dome structure herein, simplified simultaneously production technology, improve production efficiency, and in the viewing area of car body, cannot see solder joint, improved the presentation quality of whole car body.
Description of drawings
Fig. 1 is the utility model roof construction scheme drawing;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the utility model carline structural representation.
As shown in Figure 1 to Figure 3, car roof side-beam 1, carline 2, roof hoard 3, roof lower-edge beam 4, side wall cantrail 5, viewing area 6.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, the roof of stainless steel car body is connected with the connection structure of passing through between the side wall, and connection structure is comprised of car roof side-beam 1, carline 2, roof hoard 3, roof lower-edge beam 4, side wall cantrail 5.
Carline 2 arranges across the roof arrangement in parallel, and the roof hoard 3 of stainless steel car body generally adopts the ripple top board in order to gain in strength, and the mode by resistance spot welding between roof hoard 3 and the carline 2 is welded and fixed.Car roof side-beam 1, roof lower-edge beam 4 and side wall cantrail 5 mode by resistance spot welding is welded and fixed and is connected.
Car roof side-beam 1 vertically is arranged at the both sides of car body, be welded and fixed with the mode that adopts resistance spot welding between the carline 2 and be connected, as shown in Figure 3, in the present embodiment, the transversal surface of carline 2 is " second " font, and carline 2 adopts whole stamping forming integrative-structure spare, can form different profiles, can avoid like this splicing at carline 2 big or small arc transition places in the prior art, avoid welding the welding deformation that brings, also better guarantee the intensity and toughness of roof.Because the bulk strength rigidity of car roof side-beam 1 and carline 2 improves, solder joint between carline 2 and the car roof side-beam 1 can reduce quantity relatively, simultaneously, car roof side-beam 1 adopts roll-forming, by lot of experiment validation, between the two bond pad locations is optimized, make bond pad locations can avoid the viewing area 6 of roof, and then solder joint is arranged on beyond the viewing area 6, improved the overall appearance effect of car body.
The below of car roof side-beam 1 is welded and fixed roof lower-edge beam 4, and the mode by arc welding between the both ends of the surface of roof lower-edge beam 4 and carline 2 is welded and fixed and is connected, and the mode by resistance spot welding between roof lower-edge beam 4 and the side wall cantrail 5 is welded and fixed.When the car body general assembly, can regulate by the mode that the pad (not shown) is set the height of car body between side wall cantrail 5 and roof lower-edge beam 4, and then guarantee that the height of car body reaches designing requirement.
As mentioned above, given scheme content can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
