Hybrid power drive system and vehicle

Abstract

The invention provides a hybrid power drive system and a vehicle. The hybrid power drive system comprises a gearbox, a first clutch, a second clutch, a first gear, a second gear, a third gear, a fourth gear, a driving motor and a third clutch. The gearbox comprises a first input shaft, a second input shaft, a first transmission shaft and a second transmission shaft. The first clutch is arranged on the first transmission shaft. The second clutch is arranged on the second transmission shaft. The first gear and the second gear are arranged on the first transmission shaft, and the first gear is arranged close to the first input shaft. The third gear and the fourth gear are arranged on the second transmission shaft; the first gear and the third gear are engaged; the second gear and the fourth gear are engaged; the tooth numbers of the first gear and the third gear are the same; and the gearbox forms two gears. The driving motor is directly connected with the first input shaft. According to the gearbox of the hybrid power drive system, the number of parts is small, the technology is mature, and the structure is simple and easy to integrate; and owing to the fact that gear control of the gearbox is added, the power and size of the driving motor are smaller, the endurance mileage is longer, and power performance is also improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a hybrid drive system and an automobile. Background technique [0002] A few days ago, our automobile production and sales are still growing at double digits, the demand for total oil continues to increase, and the environment is getting worse. The country has implemented relevant measures to force automobile manufacturers to develop in the direction of small displacement, lightweight, and new energy. Hybrid power is currently a transitional new energy solution that is more suitable for China's national conditions. Hybrid vehicles generally require a power coupling mechanism to coordinate the power output of the engine and the motor, and can also select the power output mode to make the engine work in the economic zone, and take into account the power and comfort of the vehicle. [0003] With the improvement of people's living standards, driving in some communi...
