Abstract

The utility model discloses a railway wagon body, which comprises a floor board (1), lateral wallboards (2) and end wallboards (3), wherein the lateral wallboards (2) are positioned on two sides of the floor board (1), and the end wallboards (3) are placed at two ends of the floor board (1). Bottom edges of the lateral wallboards (2) and the end wallboards (3) are welded on corresponding edges of the floor board (1), and two lateral edges of the end wallboards (3) are deformed and bent to form right-angle flanging edges which are lapped with corresponding ends of the lateral wallboards (2) and fixed by welding. Compared with the traditional art, the railway wagon body has the advantages of simple structure, easy processing and manufacturing, less working procedures, low manufacturing cost, light overall weight and capability of being favorable for reducing energy consumption of locomotives and saving energy.

Description

A kind of lorry body

Technical field

The utility model relates to a kind of railway truck, specifically, relates in particular to the car body of railway truck.

Background technology

Traditional lorry body structure such as Fig. 4, shown in Figure 5, by component set-ups such as floor 1, framed side wallboard 2, end wall panel 3, end carriage 6, corner post 7 and corner post plates 8, wherein floor 1 is welded on the

end carriage

6,1 both sides are provided with framed side wallboard 2 on the floor, and the two ends of framed side wallboard 2 are welded on the cooresponding corner post 7 by corner post plate 8.1 two ends are provided with end wall panel 3 on the floor, and weld mutually with end carriage 6 on the base of this end wall panel 3, the dual-side of end wall panel 3 and 7 welding of cooresponding corner post.Because corner post adopts die mould angle steel or clod wash rectangle hollow shaped steel usually, perhaps adopts channel-section steel and corner post plate assembly welding to form, in process of production, Fabrication procedure is more, has increased manufacturing complexity and cost of product; In addition, the car body total weight is bigger, can increase locomotive energy consumption, is unfavorable for energy savings.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of lorry body simple, that can effectively reduce total weight and cost of making.

The technical solution of the utility model is as follows: a kind of lorry body, comprise the floor, be positioned at the framed side wallboard of both sides, floor and be positioned at the end wall panel at two ends, floor, its key is: the base of described framed side wallboard and end wall panel is welded on the corresponding sides on floor, the dual-side distortion bending of end wall panel, form the right angle flange, this flange overlaps mutually with the corresponding end of framed side wallboard, and fixing by welding.

The utility model has been cancelled corner post, corner post plate on the basis of conventional confguration, by flange overlap joint assembly welding, under the prerequisite that guarantees car body bulk strength and rigidity, reduced part between framed side wallboard and the end wall panel, has reduced Fabrication procedure, has reduced manufacturing cost; Simultaneously, reduce the car body total weight, reduced locomotive energy consumption, helped energy savings.

In order to simplify the connection mode between floor and the end wall panel, further reduce manufacturing cost, the two ends on above-mentioned floor are bending upwards, forms upper overturning, and this upper overturning overlaps mutually with the bottom of corresponding end wallboard, and fixing by welding.

Position in the close end, two ends of above-mentioned framed side wallboard is welded with the side cross band that three of upper, middle and lower are parallel to each other, all be welded with the end cross band that three of upper, middle and lower are parallel to each other on the described end wall panel, the two ends of described end cross band be positioned at cooresponding two the side cross bands of sustained height and directly link to each other, and fixing by welding.End cross band and cooresponding side cross band are formed framed structure, have improved the car body bulk strength.

Beneficial effect: the utility model is compared with conventional art, and is simple in structure, and processing and manufacturing is easy, and operation is few, low cost of manufacture, and whole total weight is light, helps reducing locomotive energy consumption, energy savings.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the B of Fig. 1 is to view.

Fig. 3 is the I portion enlarged drawing of Fig. 1.

Fig. 4 is the conventional confguration scheme drawing.

Fig. 5 is that the A of Fig. 4 is to view.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As Fig. 1, Fig. 2, shown in Figure 3, the utility model is by component set-ups such as floor 1, framed side wallboard 2, end wall panel 3, side cross band 4 and end cross bands 5, and wherein framed side wallboard 2 is positioned at the both sides on floor 1, and weld mutually with the side on floor 1 on the base of framed side wallboard 2.Described end wall panel 3 is positioned at the two ends on floor 1, and the two ends on floor 1 are bending upwards, forms upper overturning, and this upper overturning overlaps mutually with the bottom of corresponding end wallboard 3, and fixing by welding.The dual-side of described end wall panel 3 forms the right angle flange towards the direction distortion bending of framed side wallboard 2, and this flange overlaps mutually with the corresponding end of framed side wallboard 2, and fixing by welding.

Above structure has been cancelled the corner post in the conventional confguration, corner post plate and end carriage, when guaranteeing car body bulk strength and rigidity, has reduced part, has reduced Fabrication procedure, has reduced manufacturing cost; In addition, reduce the car body total weight, reduced locomotive energy consumption, helped energy savings.

From Fig. 1, Fig. 2 as can be known, position in framed side wallboard 2 close ends, two ends is welded with the side cross band 4 that three of upper, middle and lower are parallel to each other, be welded with all on the described end wall panel 3 that three of upper, middle and lower are parallel to each other and with side cross band 4 corresponding end cross bands 5, the two ends of described end cross band 5 be positioned at cooresponding two the side cross bands 4 of sustained height and directly link to each other, and fixing by welding.End cross band 5 is formed framed structure with cooresponding side cross band 4, has improved the car body bulk strength.
