Example 1

The present embodiment relates to a vehicle frame cross member structure facilitating arrangement of a brake pipe 3 between a cross member 2 of a vehicle frame assembly and a vehicle body floor assembly 1; an exemplary configuration of which is shown in fig. 1, 2 and 3.

In general, the frame cross member structure includes a cross member 2 connected between the side members on the left and right sides of the frame assembly. The beam 2 has a main body 20 and connecting plates 21 respectively provided at both ends of the main body 20; wherein the connection plate 21 is connected with the longitudinal beams on the same side, and a groove 200 arranged along the length direction of the cross beam 2 is formed at the top of the body 20.

Of course, the beam 2 has various processing manners, in this embodiment, the body 20 of the beam 2 is integrally formed by using a tubular profile, the connecting plate 21 of the beam 2 is formed by stamping a plate, and the body 20 and the connecting plate 21 are preferably fixedly connected by welding. The tubular section is adopted to process the body 20, so that the material selection is convenient, and the body 20 has good self strength; the groove 200 can be conveniently machined on the top of the body 20 by adopting the technological means such as extrusion molding, and the whole machining structure is simple and efficient.

As shown in fig. 4 and 5, the body 20 of the present embodiment includes a main section 20a, and end portions 20b located at both ends of the main section 20 a; the groove 200 is formed in the body section 20a and the end 20b is of tubular configuration. Only the groove 200 is arranged on the main section 20a of the body 20, so that the arrangement requirement of the brake pipeline 3 can be met; the two end parts 20b of the body 20 keep the original tubular structure, so that the connection area between the body 20 and the connecting plate 21 can be effectively increased, and the connection strength between the body 20 and the connecting plate 21 can be improved.

As shown in fig. 6 and 7, the cross-sectional shape of the main body section 20a may be generally in a "concave" shape due to the provision of the grooves 200; there are, of course, a wide variety of specific configurations. In the present embodiment, in the cross section of the main body section 20a, the wall body of the main body section 20a includes a main arc section 40 at the lower portion, a groove arc section 42 forming the groove 200, and top arc sections 41 provided separately on both sides of the groove 200; the groove arc segment 42, the top arc segment 41 on one side, the main arc segment 40 and the top arc segment 41 on the other side are sequentially connected to form the wall body of the whole main body segment 20 a. In the present embodiment, the connection portion between the top arc segment 41 and the groove arc segment 42 and the connection portion between the top arc segment 41 and the main arc segment 40 are smoothly transitioned. The wall body of the main body section 20a adopts a structure form of connecting a plurality of cambered surfaces, so that the required groove 200 can be effectively formed, and the whole body is easier to process and form; at the same time, good self-stiffness of the body section 20a can be maintained.

Specifically, the radii of the main arc segment 40, the groove arc segment 42, and the top arc segment 41 of the present embodiment are set gradually smaller in order. Preferably, the radius of the groove arc segment 42 is 0.3-0.5 times the radius of the main arc segment 40; the radius of the top arc segment 41 is 0.15-0.3 times the radius of the main arc segment 40. The radius sizes of the main arc line segment 40, the groove arc line segment 42 and the top arc line segment 41 are gradually reduced, so that the shape of the cross section structure of the main body segment 20a can be kept regular, and the design form has good processing performance and strength performance; and the size of the formed recess 200 is suitable for facilitating the arrangement of the brake pipe 3 therein.

In addition, as shown in fig. 5 and 7, a plurality of reinforcing plates 201 are disposed on the main body section 20a of the present embodiment at intervals, and each reinforcing plate 201 is disposed above the groove 200 perpendicular to the cross member 2 and connected to the top arc sections 41 on both sides of the groove 200. The plurality of reinforcing plates 201 are arranged at the top of the main body section 20a, so that a good reinforcing effect can be achieved on the strength of the top of the main body section 20 a; furthermore, it is also convenient to fix the passing brake pipe 3 to the reinforcing plate 201, improving the arrangement firmness of the brake pipe 3.

In addition, some mounting frames for fixing chassis parts may be provided on the body 20. The specific number of positions can be flexibly set according to actual needs. In this embodiment, the bottom of the body 20 is provided with a first mounting frame 22, and the side of the body 20 is provided with a second mounting frame 23. Some mounting frames are arranged at the bottom or the side part of the body 20, so that components such as an oil tank, a tail gas pipeline and the like at the bottom of the vehicle can be conveniently mounted and fixed.

Meanwhile, as shown in fig. 6, the connecting plate 21 of the present embodiment includes a base plate 210 and a flange 211 formed at the bottom of the base plate 210 by bending. The body 20 is connected to the base plate 210, the base plate 210 is attached to the inner side of the longitudinal beam, and the flange 211 is attached to the bottom of the longitudinal beam. The flange 211 is arranged on the connecting plate 21, so that the welding and positioning are facilitated, the contact area between the connecting plate 21 and the longitudinal beam can be effectively increased, and the connection strength between the connecting plate 21 and the longitudinal beam is improved.

As shown in connection with fig. 3 and 4, the body floor assembly 1 generally includes a floor cross member 10 and a floor side member 11. The clearance space between the cross member 2 and the vehicle body floor assembly 1 of the present embodiment is small, and particularly the clearance at the intersection between the floor side member 11 and the cross member 2 is also very small, and the brake pipe 3 is often required to pass through this portion when being disposed. Based on the above arrangement, a small gap D may be left between the cross member 2 and the vehicle body floor assembly 1, and this gap D may be set to 15mm, for example; at this time, even if a portion of the brake pipe 3 is disposed from above the recess 200, the minimum clearance d between it and the vehicle body floor assembly 1 may be about 5 mm. It will be seen that due to the presence of the recess 200, it is possible to arrange a large part of the brake pipe 3 into the recess 200, in particular the part of the brake pipe 3 below the floor stringer 11 into the recess 200, which makes the arrangement of the brake pipe 3 very convenient.

In summary, in the vehicle frame cross member structure of the present embodiment, the groove 200 is provided at the top of the body 20 of the cross member 2, and the brake pipe 3 disposed from one side of the vehicle to the other side of the vehicle can be disposed in the groove 200, so as to reduce the occupation of the space between the vehicle body floor assembly 1 and the cross member 2; in particular, the floor longitudinal beam 11 of the vehicle body floor assembly 1 and the cross beam 2 in the vehicle frame assembly are arranged up and down and mutually crossed, and the clearance between the two cross beams is very small, so that the arrangement space of the brake pipeline 3 is limited, and the problem can be well overcome by utilizing the groove 200 at the top of the body 20, thereby facilitating the arrangement of the brake pipeline 3 between the cross beam 2 of the vehicle frame assembly and the vehicle body floor assembly 1.

The groove 200 at the top of the cross beam 2 has the advantages of simple forming, low manufacturing cost of the beam body, and convenient processing construction, thereby having good practicability.
