The frame longitudinal beam 100 provided by the embodiment reasonably sets the height of each cross section of the web 30, for example, in the running process of a vehicle, the height of the cross section of the part subjected to a large load is large, and the height of the cross section of the part subjected to a small load is small, so that the web 30 is set to be of a variable cross-section structure, the torsion resistance and the shear resistance of the part subjected to a large load can be effectively improved, and the use stability and the reliability of the frame longitudinal beam 100 are improved by improving the structural strength of the frame longitudinal beam 100. Here, the cross section of the web 30 refers to a section perpendicular to the extending direction (the same length direction) of the frame rail 100.

It can be understood that the structural strength of the frame rail 100 can be increased by increasing the height of the cross section of the web 30, and the material used in the portion subjected to a smaller load can be reduced by providing the web 30 with a variable cross-section structure, so that the weight of the frame rail 100 is reduced, and the fuel consumption during use is reduced.

The top of the web 30 is sloped by providing a hem at the top of the web 30, such that the height of the cross section of the web 30 gradually changes along the length of the frame rail 100. The folding form is convenient to manufacture. In addition, by providing a ramp, the length of the top of web 30 can be increased, which further distributes the stresses acting on frame rail 100 during vehicle travel, and helps to improve the torsional and shear resistance of frame rail 100.

The frame side member 100, the dump truck frame 200, and the vehicle provided by the present applicant will be specifically described below by taking the mining dump truck frame 200 as an example.

Currently, a mining dump truck frame 200 can be divided into: flexible frame, rigid frame. The flexible frame is riveted by rivets and evolves by a road vehicle; the rigid frame adopts a welding structure, and mainly takes a typical traditional mine car as a main part. The flexible frame is mainly suitable for medium and small tonnage mining vehicles, and when the load is increased continuously, the flexible frame can not meet the requirement of transportation road conditions, so that the reliability is greatly reduced. The rigid frame can make up the deficiency of the flexible frame, and is suitable for transport vehicles of various tonnages. No matter the frame is flexible or rigid, a side beam type frame structure is generally adopted, namely, a frame main body consists of a left longitudinal beam and a right longitudinal beam, and the frame main body is integrally formed by riveting a cross beam and welding a circular tube and bears the torsion resistance of the frame. Because the riveted cross beam and the welded circular tube are not integrated with the left and right longitudinal beams, the riveting or welding position usually has cracking fault.

The mining dump truck welding frame comprises a front longitudinal beam and a rear longitudinal beam, wherein the rear longitudinal beam comprises a left longitudinal beam and a right longitudinal beam, the left longitudinal beam and the right longitudinal beam are arranged in parallel, the left longitudinal beam and the right longitudinal beam of the rear longitudinal beam are welded into a whole through round pipes, and in order to improve reliability, partial castings are added for transition.

The frame rail 100 has the advantages of simple structure, light weight, low requirement on manufacturing precision, low cost, high reliability and the like, and the production process is greatly improved. The frame rail 100 also includes a web 30, a cross plate 40, and a front cross plate 50. The number of the webs 30 is four, and the frame rails 100 are in a parallel structure, wherein the webs 30 are arranged in parallel, and the upper plate 10 and the lower plate 20 are also arranged in parallel. Meanwhile, the frame longitudinal beam 100 adopts a variable cross-section structure, the cross-section height of the part with larger load is larger, and the cross-section height of the part with smaller load is smaller, so that the weight of the frame can be effectively reduced.

In other embodiments, the structural forms of the upper door beam 211 and the lower door beam 212 are not limited to the structural forms shown in the figures, and may be a middison type suspension structure or a candle type suspension structure.

In other embodiments, the cylinder support (also called a suspension cylinder support) may be made of steel casting, or may be made of a separate part, and the web 30 is provided with a circular hole to serve as the cylinder support.

In summary, the frame rail 100, the dump truck frame 200 and the vehicle provided by the present application have at least the following advantages: 1) the left longitudinal beam and the right longitudinal beam in the related technology are arranged into an integrated structure, so that the torsion resistance of the frame longitudinal beam 100 and the dumper frame 200 provided with the frame longitudinal beam 100 is greatly improved; 2) the welding manufacturability of the frame longitudinal beam 100 is simple, and the problem that holes cannot be centered due to manufacturing errors during welding of circular tubes is avoided; 3) the frame rail 100 has high reliability, and avoids the weld joint in a high stress area, for example, the weld joint formed by welding a round pipe and the rail has high stress and is a failure high-occurrence area. 4) Most steel castings are eliminated, and cost reduction is facilitated. 5) The frame longitudinal beam 100 adopts a variable cross-section structure, the cross-section height of the part with larger load is larger, and the cross-section height of the part with smaller load is smaller, so that the weight of the frame can be effectively reduced. 6) The frame rail 100 is generally in a parallel structure, wherein four webs 30 are arranged in parallel, and the upper plate 10 and the lower plate 20 are also arranged in parallel, so that the structural strength of the frame rail 100 is further enhanced.
