Description
Technical field
This utility model belongs to rail traffic vehicles body construction field, is specifically related to a kind of vehicle body of railway vehicle door corner structure.
Background technology
On aluminum alloy bodywork of rail vehicle, door pillar and side bar junction are the important load position of car body, and this position is easily formed stress under the operating modes such as hitch tension and compression and concentrates, it is necessary to structure reasonable in design prevents stress from exceeding standard. Substantially there are following three kinds of technical schemes at present, respectively following introduction:
Scheme one: the connected mode of door pillar 1 and side bar 2 is as shown in Figure 1. This simple in construction, door pillar 1 and side bar 2 are welded by principal weld v1, v2, v3. But this structural stress concentrated area occurs in weld seam v3 position, is easily formed stress and exceeds standard.
Scheme two: the connected mode of door pillar 1 and side bar 2 is as shown in Figure 2. Can effectively dredge weld seam u3 place stress by welding transition muscle 4 to concentrate, but double welded joint u4, u5, u6, u7 need to be increased, thus causing weld seam u2 and weld seam u6 overlapping, make this critical positions decrease in strength, causing that stress exceeds standard. And transition muscle weld seam is more, after shaping, aesthetic property is not high.
Scheme three: adopt the independent door corner structure of similar Chinese patent CN201020124889, this independent door corner structure has a good stiffness, but processed complex, the production cycle is long, and manufacturing expense is high.
Utility model content
For the problems referred to above, this utility model aims to provide and can be prevented effectively from the heavily stressed weld metal zone that occurs in, simple in construction, it is easy to the vehicle body door corner structure of processing.
This utility model solves the technical scheme of problem: a kind of vehicle body of railway vehicle door corner structure, including vertical plate-like support portion, is fixed on the back side, support portion and the inner side connecting portion vertical with edge, support portion, is fixed on the back side, support portion and with support portion another side along vertical outside connecting portion and the transition muscle being fixed on lower end, front, support portion;
Described inner side connecting portion is contour with support portion, and outside connecting portion is in top, support portion;
Described transition muscle is one-body molded with support portion.
Concrete, described transition muscle is parallel is provided with two, is individually fixed in edge, support portion, and there is angle theta with edge, support portion. The purpose arranging angle is in that to meet the requirement of locomotive gauge.
Described angle theta selects as the case may be, it is preferable that 0 ��ܦȡ�10 ��.
The end face of described transition muscle is tangent with the front of support portion.
Preferably, the end face of described transition muscle is arc surface. Or, the end face of described transition muscle is the face that arc surface is formed with plane combination, is arc surface in the middle of it, and arc surface both sides are the plane being mated with.
For preventing stress from concentrating, described inner side connecting portion and connecting portion top, outside are equipped with rounding.
Offering on door pillar and side bar and the groove of door corner structure form fit, above-mentioned door corner structure snaps in groove, and the contact surface of door corner structure and door pillar and side bar all adopts and is welded and fixed.
Door corner structure of the present utility model, for the transition of door pillar and side bar, plays and dredges stress concentration, it is prevented that the effect that weld seam is overlapping. Stress concentrated position occurs on the side bar that intensity is high, thus improve the integrated carrying performance of car body. Concrete effect shows:
1. transition muscle is one-body molded with support portion so that welding capacity is few, and machining formability is good, decreases welding deformation, eliminates the decrease in strength that critical positions weld seam overlap causes.
2. transition top rib face forms rounding off, is beneficial to dredging of stress, comparatively attractive in appearance.
3. a corner structure and door pillar coupling part, stagger certain distance with parallel weld seam, is disperseed by stress.
4. this corner structure is simple, it is easy to processing, wide adaptability, can shorten the production cycle, reduces manufacturing expense, and meets aesthetic requirements.
