Abstract

The invention relates to the technical field of an automobile, in particular to a light weight bus frame which comprises annular frames, wherein the annular frames encircle a bus head, two sides of a bus and a bus tail and include a bus top annular frame, a bus waist annular frame and a bus bottom annular frame. A gap exists at a position of the bus waist annular frame, wherein the position of the bus waist annular frame located at a bus door position. The bus bottom annular frame is placed at wheel position to hunch upwards to contain wheels. A plurality of beams which are in bridge joint with two side rims of the bus bottom annular frame are arranged on the bus bottom which is further provided with longitudinal beams which are in bridge joint with the beams. The bus head, the two sides of the bus and the bus tail are all provided with a plurality of vertical beams which are in bridge joint with the annular frames which are section bar beams, and the beams, the longitudinal beams and the vertical beams are the section bar beams. The light weight bus frame is firm in structure. The section bar beams are adopted, excessive connecting pieces are not needed, and at the same time, the light weight, simple and safe requirements can be met.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a lightweight bus frame. Background technique [0002] With the increasing shortage of oil resources on the earth, fuel prices are rising steadily, and the number of cars continues to increase. If things go on like this, a car energy crisis will inevitably be ushered in; and car exhaust emissions are serious pollution to the earth's environment. Therefore, it is imperative to replace traditional fuel vehicles with new energy vehicles. Among them, electric vehicles are powered by on-board power supplies, and have relatively little impact on the environment, and their prospects are widely optimistic. Whether it is a traditional car or a new energy vehicle, the lightweight of the car body is necessary, and the lightweight of the car body has become the main research direction in the automotive field. On the premise of ensuring the safety of the vehicle, reducing the...
