Abstract

The invention provides a multi-purpose adaptive second-gear multimode stepless speed changing electric transmission integrated power system. The multi-purpose adaptive second-gear multimode stepless speed changing electric transmission integrated power system comprises a first motor and the like; a planetary gear train comprises a gear ring, a planet carrier and a sun gear; the rotor of the first motor is connected with the gear ring of the planetary gear train; the rotor of the second motor is connected with the sun gear of the planetary gear train and the input end of a transmission chain, respectively; a gear shifting device is connected with the input end of a speed reducing differential mechanism and control on power transfer from the planet carrier of the planetary gear train and the output end of the transmission chain to the speed reducing differential mechanism is realized; the output end of the speed reducing differential mechanism is connected with two wheels by use of two half shafts; a motor control device is connected with an energy storage device to transfer electric energy; the motor control device is further connected with the first motor and the second motor, respectively, and outputs control instructions. The multi-purpose adaptive second-gear multimode stepless speed changing electric transmission integrated power system has the characteristics of better technical inheritance to the existing vehicles, whole vehicle dynamic property, fuel economy and low emission.

Description

technical field

[0001] The invention relates to a power system, in particular to a multi-purpose adaptable second-speed multi-mode continuously variable transmission integrated power system. Background technique

[0002] The electrification and hybridization of automobile power has become an inevitable trend. Compared with series hybrid system and parallel hybrid system, hybrid hybrid system 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] A Chinese patent with the announcement number CN201021118Y, the announcement date of February 13, 2008, and the patent name "P...
