Problems solved by technology

However, the disadvantages of the existing full load-bearing body are that the manufacturing process is complicated, the tooling occupies a large area, and the productivity is low, thereby causing the cost to be relatively high.
In addition, different types of passenger cars cannot be produced in mixed lines, which is not conducive to saving costs and improving production efficiency

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing.

[0023] figure 1 Shown is a fully loaded body 10 according to the present invention, which can be applied to cars, passenger cars and trucks, but is especially suitable for passenger cars, increasing the reliability and safety of passenger cars. The fully loaded vehicle frame 10 includes a front wall frame 1 , a front axle frame 2 , a rear axle frame 3 and a rear wall frame 4 which are sequentially connected along the longitudinal direction (that is, the driving direction of the vehicle). Meanwhile, at least one central frame 5 can be connected between the front axle frame 2 and the rear axle frame 3 . This can effectively increase the overall length of the fully loaded vehicle body 10, so as to meet the development needs of the vehicle toward larger size. In this way, the modularity of the full load-bearing body can be achieved, making it possible to replace or change the...

Abstract

The invention provides a full-bearing car body, a method for manufacturing the same and a passenger car comprising the full-bearing car body. The full-bearing car body mainly comprises a front wall framework, a front axle framework, a rear axle framework and a rear wall framework which are longitudinally, sequentially and fittingly connected with one another. The full-bearing car body, the method and the passenger car have the advantages that a full-bearing characteristic of the traditional full-bearing car body can be kept by the four frameworks, stress on collision positions can be dispersed to the various frameworks after the full-bearing car body is collided, the frameworks can deform, and buffer regions can be increased, so that injury to passengers due to collision can be reduced; full-bearing car body manufacturing procedures can be simplified owing to a modular mode, and tool areas can be decreased; different models of passenger cars can be produced in a mixed model manner, and the full-bearing car body, the method and the passenger car are favorable for saving the cost and improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a full load bearing body, a manufacturing method thereof and a passenger car including the same. Background technique [0002] As we all know, the full load-carrying body is usually used on the bus, which can be vividly called "birdcage structure", which can greatly improve the fuel economy, stability, comfort and safety of the bus. Therefore, the fully loaded body has been widely used in the field of passenger cars. [0003] At present, the existing full load-carrying body is mainly composed of six major assemblies, the front wall assembly, the rear wall assembly, the left and right side wall assemblies, the chassis assembly and the top cover assembly. The six assemblies are usually fixedly connected to each other by welding. However, the disadvantages of the existing full-loaded body are that the manufacturing process is complicated, the tooling occupies a large area, and...
