Abstract
The invention relates to a mounting structure for an anti-side-rolling torsion bar base of a railway vehicle, belonging to the field of interior design of vehicle body. The mounting structure comprises a first web plate, a second web plate and an anti-side-rolling torsion bar mounting block, wherein the upper part of the first web plate is provided with a slot with an opening upward, the first web plate is inserted and connected with a sleeper beam inner diaphragm by virtue of the slot, the top of the first web plate is fixedly connected with a sleeper beam upper cover plate, and the middle part of the first web plate is fixedly connected with a sleeper beam lower cover plate; the top of the second web plate and the sleeper beam lower cover plate are fixed; and the anti-side-rolling torsion bar mounting block is fixed at the lower parts of the first web plate and the second web plate and is provided with two mounting holes used for mounting an anti-side-rolling torsion bar. According to the mounting structure, the stress condition of the mounting structure can be improved, and welding line fatigue is avoided.
Description
Technical field
The present invention relates to a kind of Anti-side rolling torsion bar for railway vehicle seat installation structure, belong to the in-built design field of car body.
Background technology
The sleeper beam anti-side rolling torsion rod is used on subway and high ferro vehicle in a large number, structure mounting design to this important stressed member, its structural strength especially fatigue resistance requires high, the stressed need of the construction joint of this anti-side rolling torsion rod mount pad are considered to check especially, should avoid the appearance of weld fatigue on the structure design as far as possible.Therefore, also occur such as the pattern that adopts structural fasteners to connect, it is not very high adopting fastener self impact characteristics.In in the past design, mainly pass through the sprue base assembly welding on the sleeper beam lower cover, weld seam bears the increment load power that is produced by bending, and stressing conditions is not good.
Summary of the invention
The technical problem to be solved in the present invention is: propose the stressed Anti-side rolling torsion bar for railway vehicle seat installation structure of a kind of integral body, can improve the stressing conditions of mounting structure, avoid the appearance of weld fatigue.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: comprise the first web, the second web and anti-side rolling torsion rod mounting blocks; Described the first web top has opening up slot, and pegs graft by this slot and sleeper beam internal partition, and the top of described the first web and sleeper beam upper cover plate are affixed, and middle part and sleeper beam lower cover are affixed; The top of described the second web and sleeper beam lower cover are affixed; Described anti-side rolling torsion rod mounting blocks is fixed on the bottom of described the first web and the second web, and described anti-side rolling torsion rod mounting blocks is provided with two mounting holes that are used for installing anti-side rolling torsion rod.
To the perfect of technique scheme be: the bottom of described the first web and the second web is equipped with downward opening groove, and described anti-side rolling torsion rod mounting blocks inserts in the groove of the first web and the second web bottom, and is welded and fixed.
To further improving of technique scheme be: the bottom center of described anti-side rolling torsion rod mounting blocks is provided with breach, and described two mounting holes are separately positioned on described breach both sides.
The beneficial effect that the present invention brings is: because the first web is plugged on the sleeper beam dividing plate, its top and sleeper beam upper cover plate are affixed, and middle part and sleeper beam lower cover are affixed, and the second web is fixed on the sleeper beam lower cover, adopted whole stressed structure, so effectively avoided the appearance of weld fatigue; Simultaneously, the first web and the second web are provided with the groove that Open Side Down, and the anti-side rolling torsion rod mounting blocks is provided with breach, therefore in proof strength, have alleviated deadweight, also can reduce the appearance of weld fatigue.
The present invention falls within the torsion bar mounting blocks on the web, forms similar a kind of vibration reduction and cushioning, and the subsidiary load that vertical force and moment of flexure are produced divides by two parts to be born.This mounting structure adopts similar building blocks grafting form to install, so that the location is more accurate, has realized the mistake proofing installation.
As seen, ingenious conception of the present invention, simple in structure, quick and easy for installation.The present invention will be widely used in field of track traffic, have good market outlook.
Description of drawings
Below in conjunction with accompanying drawing Anti-side rolling torsion bar for railway vehicle mount pad mounting structure of the present invention is described further.
Fig. 1 is the scheme of installation of the embodiment of the invention.
Fig. 2 is the structural representation of the first web of present embodiment.
Fig. 3 is the structural representation of the second web of present embodiment.

The specific embodiment
The Anti-side rolling torsion bar for railway vehicle mount pad mounting structure of present embodiment comprises the first web 1, the second web 2 and anti-side rolling torsion rod mounting blocks 3 with slot.
As shown in Figure 2, the first web 1 top is provided with the slot of opening upwards, is used for grafting sleeper beam internal partition, and the bottom of the first web 1 is provided with the groove that Open Side Down.In use, the first web 1 grafting sleeper beam on internal partition, and with the internal partition assembly welding, its welded top is on the sleeper beam upper cover plate; Slot at the sleeper beam lower cover, the first web 1 passes the groove on the sleeper beam lower cover, and the middle part of the first web 1 is welded on the sleeper beam lower cover.
As shown in Figure 3, the bottom of the second web 2 has the groove that Open Side Down.In use, the direct assembly welding in the top of the second web 2 and has reinforced rib to support on the sleeper beam lower cover.
As shown in Figure 4, anti-side rolling torsion rod mounting blocks 3 adopts thick bloom machinework to obtain, and its bottom center is provided with the breach that Open Side Down, and is respectively equipped with for the anti-side rolling torsion rod mounting hole is installed at the dual-side of breach.In use, anti-side rolling torsion rod mounting blocks 3 is inserted in the groove of the first web 1 and the second web 2 bottoms and assembly welding.
As shown in Figure 1, install by pegging graft and the forms such as groove welding with the first web 1 of slot, the second web 2 and anti-side rolling torsion rod mounting blocks 3, forms a whole force structure, pass through finite element analysis computation and actual items application testing, stressing conditions is good.
Anti-side rolling torsion bar for railway vehicle mount pad mounting structure of the present invention is not limited to above-described embodiment.All employings are equal to replaces the technical scheme that forms, and all drops on the protection domain of requirement of the present invention.
