Super multi-motor series stepless speed change engine

Abstract

The invention discloses a multi-motor series stepless speed change engine. The multi-motor series stepless speed change engine is characterized by comprising a base, an upper cover plate and an outer protecting cover; the base and the upper cover plate are installed at the two ends of the outer protecting cover correspondingly, and the base, the upper cover plate and the outer protecting cover form a containing cavity; the upper cover plate is provided with an output shaft serving as the output end; the containing cavity is internally provided with a spindle rotation system for driving the output shaft and not less than one collateral planet driving system; a speed change main box is of a planet structure; outer ring structure teeth and concentric bearings are added; the strength and the speed of a central motor and the strength and the speed of a slightly external motor are coupled on one output shaft through a special structure and then are coupled together layer by layer in proportion in a multistage mode; the effect that the two motors can be separated to work independently and also can be smoothly combined together to work without separating the teeth is ensured through the special structure; the technology can be used for coupling one or more motors; a plurality of speed change control modes are achieved; and the three key super engine requirements for high speed, smoothness and energy saving are met by combining the characteristics of a coreless motor.

Description

technical field [0001] The invention relates to a super multi-motor series continuously variable speed engine. [0002] technical background [0003] The most difficult thing in automobile technology is the automobile engine. It is said that the engine technology of the Chinese cannot catch up with foreign countries. Now the development of electric vehicle technology gives my country the opportunity to overtake in the development of automobiles. The key to surpassing lies in the engine. The quality of the engine determines the performance of the car. Generally, the high-efficiency working area of ​​the motor is relatively narrow, and a lot of energy is not maximized. The combination of the motor and the super transmission can solve this problem, which is to repeatedly use the high-efficiency working area of ​​the motor through the gear ratio. The motor can exert its maximum efficiency in the high-efficiency zone. [0004] Advantages and disadvantages of existing technology:...

AI Technical Summary

Problems solved by technology

[0005] 1. Gasoline / diesel vehicles have mature technology and are powerful at high speeds, but fuel consumption at low speeds, complex engine manufacturing, large noise and vibration, and do not meet the requirements for new energy development;

[0006] 2. At present, for pure electric vehicles, the engine technology is mostly high-power single motor, or multi-motor parallel technology, which has high energy consumption and high cost of making complicated cars. The battery life of mid-range cars is too little, and the speed of low-end cars is slow; It is powerful at low speed, but weak at high speed, and the motor and motor are too heavy, which cannot meet the popularization requirements;

[0007] 3. Hybrid power, low speed with electricity, high speed with oil, a better combination, but there is still a sense of frustration when shifting gears, two sets of control systems for one car, the cost is too high, and excessive solutions are difficult to popularize
