Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile manufacturing and modification, and particularly relates to a battery replacement type unmanned pure electric mine truck. BACKGROUND

[0002] Because the fuel engine has a longer development time than the motor, the technology is more mature, and the traditional mine truck can meet the use requirements by using a single fuel engine. The single fuel engine has only one power output shaft, and there is no fixed single motor fastening structure. The single motor fastening structure is simple and convenient to use. With the increasing shortage of oil resources, and the traditional fuel engine is seriously polluted, new energy gradually enters the market, and pure electric mine trucks gradually replace traditional mine trucks. However, due to the limitation of technology, the power of the motor is smaller than that of the fuel engine, and the structure is complex. The single motor driven pure electric mine truck has smaller load than the traditional mine truck, and the efficiency is low. Although the small load mine truck has application scenarios, it is difficult to meet the more extensive mining requirements. By connecting the front and rear double motors in series, the pure electric mine truck can obtain greater overall driving force, obviously improve the load of the mine truck, and meet more extensive application scenarios. However, the double motor puts forward higher requirements for the fixation of the motor. The traditional fixing plate is directly installed on the fixing beam of the traditional single motor, and the two motors cannot be fine-tuned, so it is difficult to ensure that the output shafts of the double motors are perfectly matched. When the output shafts of the double motors exceed the allowable error range, not only the overall driving force cannot be improved, but also the double motors interfere with each other, affect the motor power output, and cause the driving force to decrease. In severe cases, the motor may even be burned out. Therefore, the existing technology needs to be further improved. SUMMARY
