Embodiment Construction
[0017] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0018] Specific embodiments of the vehicle of the invention, such as Figure 1 to Figure 2 As shown, the vehicle includes a rear axle 7 and a hybrid system connected to the rear axle 7 in transmission. The hybrid system includes an engine 1 and a planetary row connected to the engine 1. The planetary row includes a sun gear 9, a planetary carrier 10 and a ring gear 4. The engine is connected to the planetary row through the planetary carrier 10 of the planetary row; the sun gear of the planetary row 9 The transmission is connected with an auxiliary motor 11, which is mainly used to generate power for the energy storage system when the engine 1 is running and to apply forward or reverse drag torque to the engine 1 when the engine 1 is started or stopped; the sun gear 9 Between the auxiliary motor 11 and the second lock-up clutch 3 for locking the rotatio...

The invention relates to a hybrid power system and a vehicle provided with the hybrid power system. The hybrid power system comprises an engine. The engine is in transmission connection with a planetrow. An auxiliary motor used for starting / stopping the engine is arranged between the engine and the planet row. The planet row is in transmission connection with a main driving motor. A gearbox is arranged between the main driving motor and the planet row. The hybrid power system further comprises a planet row output end locking clutch used for locking the output end of the planet row when the engine is started / stopped. The gearbox is arranged between the main driving motor and the planet row. A planet row output end locking clutch is arranged on a connecting section of the planet row and themain driving motor. When the auxiliary motor starts / stops the engine, the gearbox is in a neutral gear. The planet row output end locking clutch locks the output end of the planet row, so that torquegenerated when the auxiliary motor starts / stops the engine cannot be transmitted to a rear axle of the vehicle. The impact of the axle on the whole vehicle is avoided.
Description
technical field [0001] The invention relates to a hybrid power system and a vehicle using the hybrid power system. Background technique [0002] In the field of hybrid electric vehicles, series connection can realize the optimal control of the engine, but all the energy will be converted twice, and the loss is relatively large; parallel connection can achieve better transmission efficiency, but the mechanical connection between the engine and the output shaft cannot ensure that the engine is always It is in a better working area, so it is a better choice to adopt a dual-mode planetary row hybrid power system. The current dual-mode planetary row hybrid system mainly uses a planetary structure as a power splitting device. The advantage of the planetary row mechanism is that it can realize the decoupling between the engine speed and the output shaft speed, so that the control system can control the engine at any speed. Speed and torque, so as to achieve high-efficiency engin...
