[0004] In the existing all-wheel drive hybrid power system, US patent US 6,383,114 B1 relates to a THS-C four-wheel drive hybrid power transmission system of Toyota, which is specifically applied to the Toyota ESTIMA hybrid power vehicle, and the front wheel drive adopts a planetary The hybrid power transmission system with CVT has a complex structure and relatively high cost
US patent US 6,334,498B1 relates to a transmission system in which the front wheels use AT and the rear wheels use an electric drive rear axle. Because the front wheel transmission system does not have a motor, the system has a low degree of mixing and relatively poor performance.
U.S. Patent US 2006 / 0011395 A1 relates to a transmission system of Toyota that uses a planetary row for the front wheels, two motors, and an electric rear axle for the rear wheels. It is specifically applied to the Toyota LEXUS hybrid vehicle. The system uses three The main motor, the system is complex and the cost is relatively high

Abstract

A LSG four wheel drive hybrid vehicle drive mechanism with its front wheel drive adopts engine and crankshaft installed disk generator, automatic clutch and manual transmission MT or directly using AMT automatic transmission to form the drive system, with the ISG generator installed on the engine and the automatic clutch or AMT automatic transmission, with the rear wheel drive using rear wheel drive generator, rear wheel drive decelerator and differential formed electric rear axle. The overall drive scheme is simple, effective, low in cost, easy for realization, with relatively ideal vehicle matching and control effect.

Description

technical field [0001] The invention belongs to electric vehicle technology, in particular to an all-wheel drive hybrid electric vehicle technology. Background technique [0002] Hybrid electric vehicles have both the advantages of pure electric vehicles and conventional power vehicles. Compared with conventional power vehicles, they have excellent power performance, fuel economy and emission performance. The companies have carried out the research and development of hybrid electric vehicle technology, and various hybrid electric vehicles have been launched one after another, and have received extensive attention from users and the market. [0003] The all-wheel drive hybrid electric vehicle can realize four-wheel drive, which improves the passability; both the front and rear axles can recycle regenerative braking energy, which improves the energy recovery rate during regenerative braking; Power and shifting smoothness; has become one of the important directions of hybrid v...
