Abstract

The invention provides a dual-clutch transmission for hybrid power, belongs to the technical field of automotive transmissions and solves the technical problem that transmissions in the prior art are low in operating efficiency and the like. The dual-clutch transmission for hybrid power comprises a motor, an engine, a first input shaft, a second input shaft and an output shaft. The first input shaft is connected with an output end of the motor. The second input shaft is connected with an output end of the engine. A first drive gear is fixed on the first input shaft. A second drive gear is sleeved on the second input shaft. The first input shaft is connected with the second input shaft through a one-way clutch. The second input shaft is connected with the engine through a first double clutch. The second drive gear is fixed to the double clutch peripherally. A second double clutch and a third drive gear which can be connected with a differential are arranged on the output shaft. A first driven gear and a second driven gear are arranged on two sides of the second double clutch. The first driven gear and the second driven gear are meshed with the first drive gear and the second drive gear. The dual-clutch transmission for hybrid power has the advantages of high operating efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile transmissions, and relates to a dual-clutch transmission for hybrid power. Background technique [0002] As the domestic oil supply becomes more and more severe, the requirements of emission regulations become more and more stringent, and the number of non-professional drivers continues to increase, the market needs automatic transmissions with high efficiency, high comfort and low cost. At the same time, environmental protection and energy saving are the direction of automobile research. It is reflected in the transmission to improve efficiency and make the engine work in the best energy-saving state. [0003] At present, the automatic transmissions used in automobiles can be roughly divided into three categories: one is a hydraulic automatic transmission AT composed of a hydraulic torque converter, a planetary gear mechanism and an electro-hydraulic control system; the other is a traditional...
