Special vehicle frame of medium-sized snow sweeper

Abstract

The invention discloses a special vehicle frame of a medium-sized snow sweeper. The special vehicle frame of the medium-sized snow sweeper comprises a left longitudinal beam and a right longitudinal beam which are symmetrically arranged; a transmission shaft middle supporting cross beam, a first rear suspension cross beam and a second rear suspension cross beam are arranged between the left longitudinal beam and the right longitudinal beam in sequence from front to rear; two front end castings are correspondingly arranged at the front end of the left longitudinal beam and the front end of theright longitudinal beam; a cross beam mounting seat is arranged on each front end casting; first cross beams are arranged on the two cross beam mounting seats; snow removal device mounting ports are also formed in the cross beam mounting seats; and a second cross beam is also arranged between the left longitudinal beam and the right longitudinal beam. The special vehicle frame of the medium-sizedsnow sweeper has the advantages that the laying and remodeling demands of the snow sweeper are optimized to be convenient for follow-up remodeling of the snow sweeper; the frame first cross beams andthe frame front end big castings are structurally reinforced and optimized for extreme impact conditions in the snow removal process; the integral strength and reliability of the frame are enhanced; and the reliability of the frame of the snow sweeper is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of a special vehicle frame, in particular to a special vehicle frame for a medium-sized snow removal vehicle. Background technique [0002] At present, the domestic snow removal vehicle refitting companies basically use the general chassis provided by the OEM, and the frame is also a general frame for commercial vehicles. However, due to the special needs of snow removal vehicles, this type of frame cannot meet the refitting requirements. It is very difficult to modify. [0003] As the demand for special snow removal vehicles in the municipal field continues to increase, refitting plants have higher and higher requirements for the chassis, and the modularization, integration, reliability, simplification of the interface with the bodywork, and the convenience of modification of the chassis frame assembly Sex and other requirements are getting higher and higher. [0004] The patent with the publication numbe...

Problems solved by technology

[0004] The patent with the publication number CN203047365U discloses a special vehicle frame assembly. Although the structure of this frame is simple, it can meet the various refitting needs of refitting factories and simplify the difficulty of refitting, but it is not designed for snow removal vehicles. The local strength of the front end of the frame is poor, and it is difficult to withstand the impact conditions during the snow removal process. For snow removal vehicles, this type of frame has poor reliability
