Under the three-section structure of the embodiment of the application, various parts can be intensively installed on the vehicle longitudinal beam assembly 10, the installation support for independently arranging various parts is omitted, and the cab is arranged between the front and rear sets of vehicle longitudinal beam assemblies 10, so that the arrangement position of the cab is lower, the height of the mass center of the whole vehicle is reduced, and the maneuverability of the vehicle is enhanced. Meanwhile, the three-section structure can provide enough jumping space for wheels, and is beneficial to arranging an oversized travel suspension system.

Based on the same inventive concept, the embodiment of the application also provides a vehicle, including the vehicle chassis device.

As described above, in the present embodiment, the vehicle side member assembly 10 includes the side member front section 11, the side member middle section 12, and the side member rear section 13, which are connected in order. The front rail section 11 is intended to be connected to the bumper of the vehicle and the rear rail section 13 is intended to be connected to the cab of the vehicle. And the side member front section 11, the side member middle section 12, and the side member rear section 13 are provided as an integral structure, and a plurality of target components of the vehicle are mounted through a mounting surface S provided on the outer periphery of the vehicle side member assembly 10. In this way, the main frame and the auxiliary frame can be omitted, various parts are integrally installed through the vehicle longitudinal beam assembly 10, the integration degree of the vehicle chassis is improved, and the situation that the assembly consistency of the parts on the vehicle chassis is poor at present is improved. Specifically, the component brackets such as the suspension big bracket, the spring bracket, the buffer piece bracket, the shock absorber bracket, the axle bracket, the bumper bracket, the air treatment device bracket and the like can be integrated into the vehicle longitudinal beam assembly 10, namely, integrated into one part, thereby being beneficial to reducing the weight of the whole vehicle and reducing the production and assembly links. Meanwhile, the hole site errors corresponding to the two symmetrical vehicle longitudinal beam assemblies 10 are small, the difference between the positioning parameters of the left and right wheels is small, and the possibility of vehicle running deviation is reduced.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
