[0009] The effect is:

[0010] The utility model utilizes the stability of the triangular bracket as a connecting piece, and the integrated structure is convenient for workers to install; at the same time, it adopts flange bolt support and is fixed with flange nuts, which plays the role of positioning and spacing, and the positioning and spacing of the first beam and the second beam can be achieved without unnecessary adjustment.

[0011] A further improvement is that the hydraulic lock bracket assembly also includes a hydraulic lock bracket and a hydraulic lock, wherein the hydraulic lock bracket is hinged to the upper end of the triangular bracket; the hydraulic lock is fixed on the hydraulic lock bracket assembly, and the lower part of the other end of the hydraulic lock bracket is hinged to the rear suspension airbag shock absorber; the lower end of the rear suspension airbag shock absorber is hinged and fixed to the main bracket assembly.

[0012] The effect is:

[0013] In the utility model, the hinge connection of the hydraulic lock bracket and the triangular bracket and the hinge connection of the rear suspension air bag shock absorber facilitates installation and eliminates resonance.

[0014] A further improvement is that an auxiliary water tank bracket is provided at the rear of the second crossbeam of the crossbeam assembly.

[0015] The effect is that the setting of the auxiliary water tank bracket provides redundancy to the layout of the entire vehicle, providing the driver with more convenient functions.

[0016] The utility model has a simple structure, reduces weight and increases strength at the same time, and can provide a larger space for components such as the engine under the cab, which is beneficial for heat dissipation and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
