Abstract

The invention discloses a four-die stepless speed change series-parallel hybrid power driving system, belonging to the technical field of automobile hybrid driving. The system comprises an engine, a clutch, two motors, corresponding transmission chains of the two motors, a power transfer switching device, a planetary gear differential device, a deceleration differential device, an energy storage device and a motor control device. The system provided by the invention has the characteristics of better technical inheritance with existing vehicles, overall dynamic property, fuel economy and low emission, and has functions of four-die driving, stepless speed change and series-parallel system; the problems of insufficient driving power, lack in ramp starting ability, large system volume and high cost of the existing similar technologies and the problems that the stepless speed regulation of the engine cannot be realized and the batch industrialization is difficult as the electromechanical components are difficult to manufacture are solved, and organic combination of high performance, low development cost, low system cost and easy implementation of scale industrialization is realized.

Description

technical field [0001] The invention relates to a device in the field of automobile hybrid drive technology, in particular to a four-mode continuously variable speed hybrid drive system. Background technique [0002] The automotive hybrid hybrid system integrates the advantages of the series hybrid system and the parallel hybrid system and overcomes their respective shortcomings. It is suitable for all road conditions and has great performance advantages. However, the existing hybrid hybrid systems, such as the most representative THS (Toyota Hybrid System) hybrid system of Toyota Motor Corporation of Japan and its THS2 (second-generation Toyota Hybrid System) hybrid system, General Motors The company's EP (Electric Parallel) hybrid system and its AHS2 (Second Generation Advanced Hybrid System) system have complex power synthesis mechanisms and high manufacturing costs. [0003] After searching the literature of the prior art, it is found that the Chinese patent document nu...
