Problems solved by technology

At present, most of the rear-drive longitudinal hybrid transmission technology schemes adopt the planetary row series-parallel scheme, or the single-gear series-parallel technical scheme, but the fuel saving rate of these two schemes is very limited, and the fuel saving effect is not good. , pollutant emissions are still relatively large

Abstract

A dual-motor hybrid power driving system for rear drive comprises an engine, a clutch and a transmission, the transmission comprises an input shaft, an intermediate shaft, an output shaft, a first motor shaft of a first motor and a second motor shaft of a second motor, and the input shaft is provided with a first-gear driving gear, a second-gear driving gear and a transmission gear. An output driving gear, a first-gear driven gear and a second-gear driven gear are sequentially arranged on the intermediate shaft, the first-gear driving gear is meshed with the first-gear driven gear, the second-gear driving gear is meshed with the second-gear driven gear, a first input gear is fixed to the first motor shaft in the circumferential direction, and a second input gear is fixed to the second motor shaft in the circumferential direction. The second input gear is meshed with the transmission gear, an output driven gear is fixed to the output shaft in the circumferential direction, and the output driven gear is meshed with the output driving gear and the first input gear. A synchronizer is arranged between the first-gear driving gear and the second-gear driving gear or between the first-gear driven gear and the second-gear driven gear, and the engine is connected with the input shaft through a clutch.

Description

technical field [0001] The invention relates to the technical field of automobile power transmission, in particular to a dual-motor hybrid drive system for rear drive. Background technique [0002] With the continuous consumption of non-renewable energy, the lack of energy and the national restrictions on vehicle exhaust emissions have seriously restricted the development of traditional fuel vehicles. There are also clear requirements for the fuel consumption of commercial vehicles. At present, most of the rear-drive longitudinal hybrid transmission technical solutions adopt the planetary series-parallel solution or the single-gear series-parallel technical solution, but the fuel-saving rate of these two solutions is very limited, and the fuel-saving effect is not good. , the pollutant emissions are still relatively large. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to aim at the deficiencies of the prior art, and to provide a dual-motor hyb...
