Abstract

The invention discloses a multimode hybrid power transmission driving device, comprising an internal combustion engine (1), a first motor / generator (2), a second motor / generator (3), an output shaft (4), a first planetary gear train (5), a second planetary gear train (6), a third planetary gear train (7), a first clutch (8), a second clutch (9), and a brake (10). The first planetary gear train (5) comprises a sun wheel (51), a first planet carrier (52), and a first gear ring (53). One end of the first planet carrier (52) is meshed with the sun wheel (51), and the other end is meshed with the first gear ring (53). The transmission driving device is simple in structure, and is provided with an engine start reverse gear mode, and after a vehicle battery runs down, a reverse function can still be realized.

Description

technical field [0001] The invention belongs to the technical field of power transmission of hybrid electric vehicles, in particular to a multi-mode hybrid power transmission driving device with simple structure, equipped with an engine starting reverse gear mode, and capable of realizing the reverse function after the battery of the vehicle is exhausted. Background technique [0002] Energy issues, especially petroleum energy, have been one of the most concerned issues in recent years. Improving the fuel economy performance and emission performance of automobiles to solve the increasing energy problems and emission pollution problems has become the main goal of research in the automotive field, and it has also become one of the driving forces for the development and progress of modern automobiles. Before solving the endurance of electric vehicles, hybrid electric vehicles are considered to be one of the effective ways to solve the problems of energy saving and environmental...
