Abstract

The invention belongs to the technical field of power transmission, and particularly relates to a serial-parallel hybrid power transmission device. The passenger-car serial-parallel hybrid power transmission device comprises an electric generator and a motor which are not arranged coaxially. An engine input shaft is connected with an input shaft through a main clutch and a shock absorber, the input shaft is fixedly connected with a first gear, and on one hand, a second gear arranged on an intermediate shaft in an empty sleeving mode is engaged with the first gear and a seventh gear, and on the other hand, the second gear is fixedly connected with a clutch; the seventh gear is fixedly connected with an electric generator output shaft, a third gear and a fifth gear are fixedly connected with the intermediate shaft, and the third gear is engaged with a second gear; and the second gear is fixedly connected with a motor output shaft, the fifth gear is engaged with a sixth gear, and the sixth gear is fixedly connected with a differential mechanism on the output shaft. According to the serial-parallel hybrid power transmission device, the electric generator and the motor are not arranged coaxially so that the axial space of the transmission device can be shortened, and the serial-parallel hybrid power transmission device is suitable for passenger cars where A-grade to C-grade transverse engines are arranged.

Description

technical field [0001] The invention belongs to the technical field of power transmission, in particular to a series-parallel hybrid power transmission device. Background technique [0002] Hybrid transmission technology is an important means of energy saving and emission reduction for passenger vehicles, and major automobile manufacturers are actively developing it. Toyota's THS hybrid technology has a good fuel-saving effect. The planetary mechanism is used for power splitting to ensure that the engine always works in the economical range, but the planetary mechanism has higher requirements. The hybrid power system in series form can ensure that the engine works in the economical range, which is suitable for frequent start and stop, severe load changes, urban driving and other working conditions; but for high-speed stable working conditions, due to one more energy conversion, the efficiency is low. The parallel hybrid power system is suitable for high-speed working condit...
