Chassis structure of pure electric automobile

Abstract

The invention discloses a chassis structure of a pure electric automobile. The chassis structure comprises a front axle, a rear axle, an automobile beam assembly, and a battery pack, a direct-current (DC) converter and a driving device arranged on the automobile beam assembly, wherein the automobile beam assembly comprises a two longitudinal beams and a plurality of crossbeams for connecting the two longitudinal beams into a whole; the battery pack and the driving device are arranged on the inner side of the two longitudinal beams; the driving device is arranged close to the rear axle and used for driving the rear axle; and the battery pack is arranged between the driving device and the front axle. The chassis structure provided by the invention is reasonable in arrangement and uniform in loading, can save energy and reduce consumption, and has the advantages of improving the journey continuation mileage, preventing the battery pack from being stolen and collided, reducing the manufacturing cost and the like.

Description

Technical field: [0001] The invention relates to the chassis structure of pure electric vehicles (such as pure electric agricultural vehicles, commercial vehicles, passenger vehicles, etc.). Background technique: [0002] At present, due to the pollution of fuel vehicles to the environment and the rising international oil prices, various automobile manufacturers have increased the pace of research on new energy vehicles, especially pure electric vehicles, which have become the research direction of domestic and foreign automobile companies. [0003] However, due to the limitation of the development level of storage battery technology, the existing pure electric vehicles have the problem of short cruising range. The layout of the vehicle itself is optimized to achieve the purpose of increasing the cruising range, resulting in many unreasonable structural designs of existing pure electric vehicles. [0004] For example, the batteries used to provide power are respectively ins...

AI Technical Summary

Problems solved by technology

Because the distance between the driving motor and the rear axle is too far, there are many transmission links in the middle. First, mechanical transmission failures are prone to occur, which increases maintenance costs and repair times; The transmission efficiency is not high, and the energy waste is serious; moreover, it also makes the weight of the whole vehicle heavy and the front and rear counterweights of the chassis are uneven, etc.
