[0106] As shown in the drawings, Figure 2 The upper end frame assembly 22 is installed on the bottom frame assembly 21 through the fastening bolt group 23, to jointly form the front section auxiliary frame assembly 11 shown in the drawings. Figure 1

[0107] As shown in the drawings, Figure 1 The front section auxiliary frame assembly 11 and the rear section auxiliary frame assembly 12 are respectively installed on the longitudinal beams of the chassis, to complete the installation of the segmented multifunctional auxiliary frame.

[0108] The segmented auxiliary frame assembly disclosed by the application is arranged in a segmented and variable cross-section longitudinal beam structure form (the cross-section sizes of the front section auxiliary frame longitudinal beam and the rear section auxiliary frame longitudinal beam are different) according to the weight distribution characteristics of the upper-mounted snow plow, which can optimize the reasonable stress of the auxiliary frame, reduce the monomer weight and the length size of the auxiliary frame, facilitate production and transportation, and simultaneously facilitate the concentration of various supports of the upper-mounted hydraulic system and pneumatic system on the front section auxiliary frame, to form the small-sized and support concentrated front section auxiliary frame, which is combinable and multifunctional, and is convenient for inspection and maintenance. The segmented auxiliary frame can be independently produced and hoisted, and has obvious process advantages.

[0109] ​In addition, the disclosed auxiliary frame assembly is reasonable in stress and light in weight: in the design and production process of the snow removing vehicle, according to the structure and weight distribution of the upper installation, in order to reasonably reduce the single weight and reasonably bear the weight of the upper installation, the auxiliary frame of the snow removing vehicle is designed in sections, the front section of the auxiliary frame mainly bears the weight of the transfer case, hydraulic oil tank, pipeline and valve body, the height of the auxiliary frame longitudinal beam can be smaller because the load of the front section is small, the rear section bears the weight of the spreader, snow blower and snow melting agent, the weight is large, so the size of the longitudinal beam of the rear section of the auxiliary frame is kept unchanged, the sectional design is equivalent to a variable cross-section structure, the auxiliary frame is not only light in weight, but also reasonable in stress structure, and the size of the whole is smaller, which is more convenient for transportation and installation operation, and more economical.

[0110] The design of the variable cross-section sectional auxiliary frame can not only reduce the weight and balance the stress, but also simplify the process, facilitate production and transportation.

[0111] The combination of various supports is concentrated in function: various supports such as the transfer case, oil pump, hydraulic oil tank, radiator, distribution valve and the like are concentrated and installed on the front section of the auxiliary frame, and the various supports are connected with the auxiliary frame through welding or bolts, which is convenient for separate assembly, hoisting and installation. In addition to the components connected and installed with the chassis longitudinal beam, the front section of the auxiliary frame also concentrates the oil tank support, radiator support, side protection support, tank plate mounting hole, various oil pipes and line small supports. The structure arrangement space is large, and the pipeline arrangement is smooth.

[0112] The front section of the auxiliary frame assembly 11 is not only small in overall size and light in weight.

[0113] Moreover, it is a combined, centralized and multipurpose auxiliary frame; it is convenient for checking, repairing and debugging of parts;

[0114] Obviously, the specific implementation of the present application is not limited by the above-mentioned manner, and various non-essential improvements made by adopting the method concept and technical scheme of the present application are within the protection scope of the present application.
