Abstract

The invention discloses a spine central keel full-bearing vehicle body, wherein the central keel comprises a driver zone floor framework, a front suspension zone framework, a middle piece framework, a rear suspension zone framework and an engine zone framework; the middle piece framework comprises a passenger floor framework, a storage room floor framework and a framework for connecting an upper floor and a lower floor; and the framework for connecting the upper floor and the lower floor is a planar frame which is composed of an upper beam, a lower beam, a plurality of longitudinal beams and a plurality of inclined struts, and the longitudinal beams and the inclined struts are arranged between the upper beam and the lower beam. In the invention, the frameworks symmetrically arranged on both sides of the keel are moved towards the middle to combine a planar trussed construction arranged on the left and right symmetric surfaces of the vehicle body, thus the truss arranged on the left and right symmetric surfaces of the vehicle body has no influence on the volume of the middle piece storage room with left and right openings no matter the inclined struts are provided or not. Therefore, the strength, the rigidity and the security of the vehicle body are greatly enhanced, and the utilization ratio is improved.

Description

technical field

[0001] The invention relates to a passenger car body, in particular to a spine-type central keel full-carrying body. Background technique

[0002] The bus body structure can be divided into non-load-bearing body, semi-load-bearing body and full-load body according to its load-bearing mode. With its advantages of light weight, high rigidity and good safety, the fully loaded body represents the mainstream direction of the development of bus body structure. The body structure of full-loaded passenger cars was proposed and designed by Setra for the first time. At present, Benz-Setra and MAN-Neoplan are mainly in the leading position in the full-loaded passenger car technology.

[0003] Although there are obvious differences in the structural styles of Benz-Setra and MAN-Neoplan full-loaded car bodies, their structural forms belong to the same category from the perspective of structural mechanics. Space frame structures such as Figure 1A , Figure 1B Flat floo...
