Abstract

The invention provides a series-parallel type double planet tooth row gear structure. The series-parallel type double planet tooth row gear structure comprises an engine, a first motor, a second motor, an output shaft, a first planet row and a second planet row. The first planet row comprises a first sun gear, a first planet carrier and a first tooth ring. The second planet row comprises a second sun gear, a second planet carrier and a second tooth ring and further comprises a second clutch. The engine is connected with the first motor, the first motor is connected with the first sun gear, and the first sun gear is connected with the first planet carrier. The first planet carrier is connected with the second tooth ring to constitute a first planet carrier tooth ring which is connected with the output shaft. The first tooth ring is connected with the second planet carrier to constitute a second planet carrier tooth ring which is connected with the output shaft. The second planet carrier is further connected with the second motor through the second sun gear. The second clutch is further connected with the first planet carrier tooth ring. The effects of improving the power performance and transmission efficiency of a vehicle are achieved.

Description

technical field [0001] The invention relates to the design field of variable speed drive systems of automobiles, in particular to a mixed-connection double planetary gear structure. Background technique [0002] A hybrid vehicle refers to a vehicle that is equipped with two power sources at the same time - a thermal power source (generated by a traditional gasoline engine or a diesel engine) and an electric power source (battery and electric motor). The actual operating conditions of the whole vehicle require flexible regulation, while the engine keeps working in the area with the best overall performance, thereby reducing fuel consumption and emissions; according to the connection mode of the hybrid drive, the hybrid system is mainly divided into the following three categories: serial type Hybrid system, parallel hybrid system, hybrid hybrid system; [0003] The characteristic of the hybrid power system is that the internal combustion engine system and the motor drive syst...
