Abstract

The invention discloses a high performance underpan framework assembly used for a pure electric bus. The high performance underpan framework assembly used for the pure electric bus comprises a framework assembly. The framework assembly comprises a front door stepping assembly, a middle battery bilge framework assembly, a rear door stepping assembly and a rear battery bilge framework assembly with positions of which are matched with each other correspondingly. The front door stepping assembly, the middle battery bilge framework assembly, the rear door stepping assembly and the rear battery bilge framework assembly are correspondingly connected through a supporting frame module. The framework assembly is welded by adopting gas shielded welding and is rust and corrosion prevented by rust removing before welding and smoothly grinding after welding. According to the high performance underpan framework assembly used for the pure electric bus, by designing the modularized front door stepping assembly, the modularized middle battery bilge framework assembly, the modularized rear door stepping assembly and the modularized rear battery bilge framework assembly, and the supporting frame module is connected by adopting gas shielded welding, bend resistant rigidity of a bus frame is improved, greater load can be borne, resonance generated by an underpan is reduced, rust and abrasion of the underpan of the bus can be effectively protected, and elastic contact between the bus frame, a bus body and bus wheels or a bus axle is kept.

Description

technical field

[0001] The invention belongs to the technical field of passenger car chassis, in particular to a high-performance bottom frame assembly for pure electric passenger cars. Background technique

[0002] The bus chassis refers to the chassis of the bus. The function of the chassis is to support and install the engine of the bus and its various components and assemblies, form the overall shape of the car and receive the power of the engine to make the bus move and ensure normal driving. Almost all the frames of the body and chassis of the buses produced at home and abroad are rigidly welded together to bear the forces of all aspects. The design of the frame structure should meet the requirements of the body to the chassis frame to the greatest extent on the premise of ensuring its performance.

[0003] The frame is subjected to complex forces, and the cross-sectional shapes and connection methods of longitudinal beams and beams are various. At present, the resea...
