Bus frame structure of full-carrying type pure electric bus

Abstract

The invention relates to a bus frame structure of a full-carrying type pure electric bus, and belongs to the field of a pure electric bus. The structure comprises a top cover framework assembly, a front wall framework assembly, a back wall framework assembly, a left side wall framework assembly, a right side wall framework assembly, a chassis framework assembly and a floor framework assembly, wherein all the assemblies are respectively formed by truss structures, the structure of the chassis framework assembly comprises a bin-type longitudinal beam which is arranged at the position of a central symmetric line, bin type attached beams which are arranged on both sides of the bin type longitudinal beam, bin type auxiliary beams which are arranged on both sides of the front and rear end parts of the bin type longitudinal beam, and the chassis framework assembly is limited on a wheel shaft by a hanging system. The bin type longitudinal beam, the bin type attached beams and the bin type auxiliary beams which are arranged on the chassis framework assembly ensure a big enough space for arranging a battery bin, an auxiliary system and baggage, the repair and the change of the battery bin are more convenient and faster, and besides, the carrying capacity of a bus body and the torsion rigidity of the bus body are further enhanced.

Description

technical field [0001] The invention belongs to the field of pure electric passenger cars, and relates to a frame structure of a pure electric passenger car, in particular to a frame structure of a full-loaded pure electric passenger car. Background technique [0002] Today, when the country vigorously promotes new energy buses, more and more automobile companies have launched electric bus products one after another. The frame structure of electric buses at the present stage is improved from the frame structure of traditional fuel buses, but this kind of frame The structure has become less and less suitable for the development requirements of electric buses. [0003] First of all, since the electric bus has replaced the power source compared with the traditional bus, it needs a large enough battery storage space to provide the placement of the power battery to ensure the endurance, and fully consider the motion balance problem caused by the weight distribution of the whole v...

Problems solved by technology

[0005] Finally, although the entire frame structure participates in the load deformation when the bus is running and under force, the upper and lower structures are not a whole. When an accidental collision occurs, a fatal accident may occur due to chassis displacement, and the mechanical structure of the vehicle body has not reached the best stable balance. State, so this also requires a new frame structure to enhance the body strength, rigidity, torsional strength, etc.
