Abstract
The utility model provides a sleeper beam covering plate and a rail wagon. The sleeper beam covering plate is provided with a lateral side capable of being welded and fixed with a sleeper beam lower covering plate of the rail wagon, wherein the lateral side is in a curve shape. After the sleeper beam covering plate and the sleeper beam lower covering plate are welded together along the curved lateral side, a weld joint is in a curve shape and has no perpendicular transition. Compared with the prior art, stress concentration is avoided, the length of the weld joint can be increased due to the curved shape, and the strength of the weld joint can be improved.
Description
Technical field
The utility model relates to the railway truck structure technology, relates in particular to a kind of body bolster cover and railway truck, belongs to the railway truck field.
Background technology
Sleeper beam is one of topmost stressed member of railway truck; Usually with the central sill of railway truck between be connected and can adopt body bolster cover to strengthen; As depicted in figs. 1 and 2, after body bolster cover 1 and 2 welding of sleeper beam lower cover again with the central sill weld together, can strengthen simultaneously sleeper beam and central sill.
Raising along with Freight Car Axle Load, speed; The fatigue reliability of structure becomes the principal element that influences heavy haul transport safety and overall economic efficiency; Improve the structural fatigue reliability and become one of heavy-duty freight car gordian technique, the crucial part that improves the structural fatigue reliability is the rigidity coordination.
Existing body bolster cover 1, its side are linearity and the right angle transition are arranged, and above-mentioned shape has determined body bolster cover when being connected with the sleeper beam lower cover, and weld seam is that straight weld 3 and junction are right angle weld seam 4, and the rigidity sudden change causes weld metal crack easily.
The utility model content
The utility model provides a kind of body bolster cover and railway truck, and to solve existing body bolster cover and sleeper beam lower cover junction stress concentration, the defective that intensity is low improves fatigue reliability.
The utility model provides a kind of body bolster cover on the one hand, has to weld fixed sides with the sleeper beam lower cover of railway truck, and wherein, said side is the curve-like side.
Aforesaid body bolster cover, wherein, preferably, said body bolster cover has two relative sides, and the profile of each side is the M shape.
Aforesaid body bolster cover, wherein, preferably, said body bolster cover is provided with the opening that is used for loss of weight.
The utility model provides a kind of railway truck on the other hand, comprises the body bolster cover and the sleeper beam lower cover that are weldingly fixed on together, and wherein, said body bolster cover is the body bolster cover that the utility model provides.
Body bolster cover that the utility model provides and railway truck make it when welding with the sleeper beam lower cover through the side of body bolster cover is arranged to curve-like, and the weld seam of formation is a curved welding seam, improve rigidity and coordinate, and have avoided stress concentration.
Description of drawings
Fig. 1 is the structural representation of body bolster cover in the prior art.
Fig. 2 is the coupled condition scheme drawing of body bolster cover and sleeper beam lower cover in the prior art.
The body bolster cover structural representation that Fig. 3 provides for the utility model embodiment.
The body bolster cover that Fig. 4 provides for the utility model embodiment and the coupled condition scheme drawing of sleeper beam lower cover.
Reference numeral:
The 1-body bolster cover; 2-sleeper beam lower cover; The 3-straight weld;
4-right angle weld seam; The 5-side; The 6-opening.
The specific embodiment
The body bolster cover that the body bolster cover structural representation that Fig. 3 provides for the utility model embodiment, Fig. 4 provide for the utility model embodiment and the coupled condition scheme drawing of sleeper beam lower cover, the utility model embodiment provides a kind of body bolster cover 1; Have and can weld fixed sides 5 with the sleeper beam lower cover 2 of railway truck, wherein, this side 5 is a curve-like; Shown in Fig. 3 and 4, body bolster cover 1 and sleeper beam lower cover 2 behind curvilinear 5 weld togethers, the curved shape of weld seam and do not have the right angle transition; Compared with prior art; Avoided the phenomenon of stress concentration, curve shape can increase the length of weld seam simultaneously, can improve the intensity of weld seam.
In practical application, body bolster cover 1 has two relative sides 5, and profile that can curvilinear 5 is set to the M shape, and symmetrically arranged M shape side edge shape rule is easier to processing.
Preferably, body bolster cover 1 is provided with the opening 6 that is used for loss of weight, and is as shown in Figure 3, and concrete qualification is not done at this in the position that is provided with of this opening 6, as long as avoid weld seam.
The utility model embodiment also provides a kind of railway truck, comprises the body bolster cover 1 and sleeper beam lower cover 2 that are weldingly fixed on together, wherein, and the body bolster cover that this body bolster cover 1 provides for the utility model any embodiment.
Body bolster cover that the utility model embodiment provides and railway truck make it when welding with the sleeper beam lower cover through the side of body bolster cover is arranged to curve-like, and the weld seam of formation is a curved welding seam, improve rigidity and coordinate, and have avoided stress concentration.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
Claims (4)
1. a body bolster cover has and can weld fixed sides with the sleeper beam lower cover of railway truck, it is characterized in that said side is the curve-like side.
