Abstract

The invention belongs to the technical field of power transmission, and in particular relates to a hybrid multi-speed gearbox. Multi-degree-of-freedom power shift parallel hybrid multi-speed gearbox, the technical solution is: the power of the engine passes through the clutch and then the input shaft to the engine input shaft; the motor module includes the motor and the reduction planetary row. Rotating speed. The gearbox main box module is composed of multiple free fixed shaft gear mechanisms, which can couple the power of the engine and the motor, and can realize five gears matching the engine and three gears matching the motor. The gearbox sub-box module can realize two gears, high gear and low gear, and work together with the input module of the gearbox main box to realize nine gears matching the engine and five gears matching the motor. The invention realizes power shifting, improves vehicle power performance, improves shifting quality, reduces clutch wear and improves fuel economy.

Description

technical field [0001] The invention belongs to the technical field of power transmission, and in particular relates to a hybrid multi-speed gearbox. Background technique [0002] Hybrid technology has the advantages of reducing emissions and fuel consumption, and at the same time can improve vehicle dynamic performance, becoming the future development direction of automotive power transmission technology. In the parallel hybrid technology, the motor mainly realizes the boosting under the rapid acceleration condition or the low-speed engine condition, improves the power performance, and improves the fuel economy of the engine; under the deceleration condition, the braking energy recovery is realized; Under these conditions, pure electric drive conditions can be realized. Compared with the series hybrid technology, which is more suitable for low-speed urban vehicles with frequent start-stop conditions, the parallel hybrid technology is more suitable for commercial vehicles, ...
