Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0029] Such as figure 1 As shown, the present invention provides a load-bearing passenger car body structure with a safety partition, which is a new type of body structure designed on the basis of the parallel three-truss type full load-bearing body structure proposed by the inventor. The body structure of the three-truss full-loaded bus includes three parts: the middle truss, the left truss and the right truss. The overall bending load-bearing structure formed by these three parts bears the main bending load borne by the body when the vehicle is running, and meets the strength and rigidity of the bus. performance requirements, such as image 3 As shown, on the basis of the original front wall 330, left wall 340, rear wall 350, right wall 360, top cover 370 and bottom frame ...

Abstract

The invention discloses an integral body structure of a large highway bus with a safety partition. The body structure comprises a first safety partition in front of the body structure, wherein the upper portion of the inside upright post of the first safety partition is fixed on the front beam of the top cap of the body structure, the lower portion is fixed on the front lower beam of the chassis of the body structure. Multiple first inclined struts are arranged between the inner side upright post and the front side periphery of the body structure, and the first inclined struts and the inner side upright post form multiple triangular structures; a second safety partition is positioned at the rear part of the body structure, wherein the upper portion of the inner side upright post of the first safety partition is fixed on the rear beam of the top cap of the body structure, the lower portion is fixed on the rear lower beam of the chassis of the body structure. Multiple second inclined struts are arranged between the inner side upright post and the rear periphery of the body structure, and the second inclined struts and the inner side upright post form multiple triangular structures.

Description

technical field [0001] The invention relates to the field of passenger car body structures, in particular to a load-bearing large highway passenger car body structure with a safety partition. Background technique [0002] The full load-bearing bus body structure is a space structure form of the bus body which is composed of grille underframe and body frame and can bear all loads, also known as "bus load-bearing body". Theoretically, the full load-bearing body structure should have the advantages of low weight, high rigidity, high safety, high fuel economy, and good comfort compared with non-load-bearing and semi-load-bearing body structures, and it is the mainstream direction of the development of bus body structures. In order to improve the safety of large highway tourist buses, GB7258-2012 "Technical Conditions for Safety of Motor Vehicles" stipulates that for road buses, tourist buses and all sleeper buses with a vehicle length greater than 11m, the body should be a full-...
