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
Sleeper beam anti-side rolling torsion rod is widely used on subway and high ferro vehicle, the structure installment of this important stressed member is designed, its structural strength especially fatigue resistance requires high, consider especially to check to the stressed need of the construction joint of this anti-side rolling torsion rod mount pad, structure design should be avoided the appearance of weld fatigue as far as possible.Therefore, the pattern such as adopting structural fasteners to connect also occurs, and adopts fastener self impact characteristics not to be very high.In design in the past, mainly through sprue base assembly welding on sleeper beam lower cover, weld seam bears the increment load power by bending generation, and stressing conditions is not good.
Summary of the invention
The technical problem to be solved in the present invention is: propose the Anti-side rolling torsion bar for railway vehicle seat installation structure that a kind of entirety is stressed, can improve the stressing conditions of mounting structure, avoid the appearance of weld fatigue.
The present invention is the technical scheme solving the problems of the technologies described above proposition: comprise the first web, the second web and anti-side rolling torsion rod mounting blocks; Described first web top has opening up slot, and by this slot and the grafting of sleeper beam internal partition, top and the sleeper beam upper cover plate of described first web are affixed, middle part and sleeper beam lower cover affixed; Top and the sleeper beam lower cover of described second web are affixed; Described anti-side rolling torsion rod mounting blocks is fixed on the bottom of described first web and the second web, and described anti-side rolling torsion rod mounting blocks is provided with two for installing the mounting hole of anti-side rolling torsion rod.
Perfect to technique scheme: the bottom of described 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 improving further 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 sleeper beam dividing plate, its top and sleeper beam upper cover plate affixed, middle part and sleeper beam lower cover affixed, the second web is fixed on sleeper beam lower cover, have employed overall stressed structure, so effectively prevent the appearance of weld fatigue; Meanwhile, the first web and the second web are provided with the groove that Open Side Down, and anti-side rolling torsion rod mounting blocks is provided with breach, therefore while proof strength, alleviate deadweight, also can reduce the appearance of weld fatigue.
Torsion bar mounting blocks falls within web by the present invention, forms similar a kind of vibration reduction and cushioning, is divided by the subsidiary load that vertical force and moment of flexure produce and is born by two parts.This mounting structure adopts similar building blocks grafting form to install, and makes location more accurate, achieves mistake proofing and install.
Visible, ingenious conception of the present invention, structure are simple, quick and easy for installation.The present invention will be widely used in field of track traffic, have good market outlook.

Detailed description of the invention
The Anti-side rolling torsion bar for railway vehicle mount pad mounting structure of the present embodiment, comprises the first web 1, 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, and for grafting sleeper beam internal partition, 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 internal partition assembly welding, its welded top is on sleeper beam upper cover plate; Sleeper beam lower cover is slotted, and the first web 1 is through the groove on sleeper beam lower cover, and the middle part of the first web 1 is welded on 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 top of the second web 2 on sleeper beam lower cover, and has reinforced rib to support.
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 installing anti-side rolling torsion rod mounting hole at the dual-side of breach.In use, during anti-side rolling torsion rod mounting blocks 3 is inserted into bottom the first web 1 and the second web 2 groove and assembly welding.
As shown in Figure 1, the first web 1, second web 2 of band slot and anti-side rolling torsion rod mounting blocks 3 is installed by grafting and the form such as groove welding, form an overall force structure, 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 the technical scheme of replacing and being formed, and all drop on the protection domain of application claims.
