Bus skeleton

Abstract

The invention relates to a bus skeleton. The bus skeleton comprises a front wall, a back wall, a left wall, a right wall and a top wall, wherein the front wall, the back wall, the left wall, the right ball and the top wall are combined to form a cuboid bus skeleton. The bus skeleton has the following advantages: the bus skeleton adopts an all-aluminum structure to largely reduce the body weight. A stand column 1 and a stand column 2 of the bus skeleton both extend to the outer sides to take arc shapes, so that the outline is more smooth, and the product beauty is enhanced; a strengthened structure of the bus skeleton can improve the stability of the front wall; a triangular structure enables the structural strength of the front wall to be further enhanced; a protection structure of the bus skeleton can improve the safety; three edges of a rectangular frame B of the bus skeleton are all arched, so that the outline is more smooth, and the product beauty is promoted; and the strengthened structure of the bus skeleton can improve the stability of the front wall.

Description

Technical field [0001] The invention relates to an aluminum profile structure, in particular to a bus frame structure. Background technique [0002] At present, the main structural forms of bus body are: 1. Non-load-bearing type, with an independent frame, the body and the frame are flexibly connected, and the carrying body is the frame; 2. Semi-loading type, with an independent frame, the body and the frame Rigid connection, the main body of the bearing is the frame, and the body part participates in the bearing. These two traditional structures will shift the chassis and body when impacted. The body is easily deformed and twisted, the strength of the entire vehicle is weak, the weight of the entire vehicle is large, the center of mass is high, and the power and fuel economy are poor. [0003] To this end, Chinese patent CN 101503099A discloses a "large-scale rectangular tube underframe full-bearing bus body", including an underframe. The left and right ends of the underf...

Problems solved by technology

Due to the existence of the step structure, not only the height of the vehicle body is increased, but also it is inconvenient for passengers to get on and off the car, and passengers are often crowded in the entrance area

[0004] At present, the body frame on the market is made of iron, which is heavy and consumes a lot of energy. At the same time, some body frames are made of aluminum, but the structure has not changed, which directly affects the performance of the body. Therefore, there is an urgent need A bus frame that can meet the comprehensive performance of the all-aluminum body has been developed. After searching, no technical solution identical or similar to the present invention has been found
