Abstract

The invention discloses a chassis of a pure electric vehicle. The chassis comprises a refitted chassis, an electric motor is arranged in the position which is left after an engine above a front axle is detached on a frame of the refitted chassis, an output shaft of the electric motor is in rigid connection with a clutch through a flange disc for transferring power to a transmission and the front axle, a plurality of batteries for providing electric power for the electric motor are assembled on the frame, all the batteries are divided into four parts, and the four parts are mounted on first, second, third and fourth battery mounting frames which are correspondingly arranged on the frame. According to the chassis of the pure electric vehicle, disclosed by the invention, the batteries are arranged at the front part and the back part in a dispersed manner, the requirements of urban vehicle usage can be met without changing the position of the mass center of the chassis of the original vehicle and the integral structure as far as possible and the production cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to a pure electric vehicle chassis. Background technique [0002] The rapid development of the automobile industry and the continuous increase of people's demand for the use of automobiles have led to a continuous increase in the production and ownership of automobiles, thus exacerbating the energy and environmental issues that people are currently concerned about. Pure electric vehicles have the characteristics of low noise, no pollution, diversified energy sources, and high energy efficiency. They are an important way to solve the problem of automobiles in urbanization. The development of pure electric vehicles will have a profound impact on adjusting my country's industrial structure, improving innovation capabilities and market competitiveness in key areas, and promoting coordinated economic and social development. From the perspective of the development of the automobile indus...
