Abstract

The invention discloses a hybrid transmission driving device. The hybrid transmission driving device comprises an internal combustion engine (1), a first electric motor / power generator (2), a second electric motor / power 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 clutch I (8), a clutch II (9) and a brake (10), wherein the first planetary gear train (5) comprises a sun gear I (51), a planetary carrier I (52) and a gear ring I (53); one end of the planetary carrier I (52) is engaged with the sun gear I (51); and the other end of the planetary carrier I (52) is engaged with the gear ring I (53). The hybrid transmission driving device disclosed by the invention is advantaged in that the structure of the device is simple; and as the device has an engine starting reversing mode, the reversing function can be achieved after a battery of a vehicle is exhausted.

Description

technical field [0001] The invention belongs to the technical field of power transmission of multi-mode hybrid electric vehicles, in particular to a hybrid power transmission drive device with simple structure, equipped with an engine start 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 prot...
