A bearing type special school bus full-enclosed ring whole vehicle structure

Abstract

The invention discloses a bearing type special school bus full-enclosed ring whole vehicle structure, comprising a chassis and a whole vehicle frame, wherein the chassis is horizontally installed under the whole vehicle frame. A chassis frame is arranged on the chassis, a plurality of brackets are vertically arranged at equal distances between two end sidewalls of the chassis frame, and a plurality of frame longitudinal beams are longitudinally arranged at equal distances between two ends of the chassis workshop. The invention has the advantages that: As that top cross beam is utilize, Sidetop cross member, Upper girder, lower girder and skirt girder, the adjacent integral bearing closed ring is welded and assembled by carbon dioxide shielded welding, As that stress can be effectively transmit and digested between the integral load-bearing close rings through the top cross beam, the side top cross beam, the upper waist beam, the lower waist beam and the skirt beam, the shaking amplitude of the whole vehicle structure when move and the collision and wear between the components are reduced, and the firmness of the whole vehicle structure is improved; The bearing type special school bus full-enclosed ring whole vehicle structure has good social benefits and is suitable for popularizing and using.

Description

technical field [0001] The invention relates to a complete vehicle structure, in particular to a load-bearing special school bus fully closed loop complete vehicle structure, belonging to the technical field of school bus complete vehicle structure application. Background technique [0002] At present, in the domestic bus market, a variety of school bus products have been developed successively, basically covering products with a length of 5m to 11m. Among them, more and more customers prefer to choose school bus products with better safety performance and better reliability in terms of model selection. [0003] Although more and more school bus products have been put on the market one after another, the functions of the whole vehicle structure of the school bus products are still not perfect. The strength, hardness and sealing degree of the whole vehicle structure of the school bus are poor, which leads to the low safety of the school bus in use. , the whole vehicle struct...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the function of the vehicle structure of the existing school bus product is still not perfect, and the strength, hardness and sealing degree of the vehicle structure of the school bus are relatively poor, resulting in a very low safety of the school bus in use. The structure of the whole vehicle is easy to be forced and rolled over when it is driven. The firmness and stability of the connection of the various components of the school bus structure are very poor. Vibration, rubbing and damage lead to the problem of low service life of the whole vehicle structure of the school bus, and a fully closed-loop vehicle structure of a load-bearing special school bus is proposed
