[0077] Such as figure 1 As shown, the hybrid drive system provided by the first embodiment of the present invention includes an engine 1, a first motor 2, a second motor 3, a connection and disconnection unit 4 and a transmission, and the first motor 2 is the same as the engine 1 The shaft is arranged, and the second motor 3 is arranged side by side with the engine 1 . The restriction of the matching surface of the second motor 3 and the engine 1 is eliminated, and the outer diameter of the second motor 3 can be increased. Since the first motor 2 is coaxially arranged with the engine 1, the side structure can be reduced and the mountability can be improved.

[0078] The transmission includes the first shaft 5, the second shaft 6, the third shaft 7, the first synchronizer S1, the second synchronizer S2, the driving gear 8 of the first gear of the first motor, the driving gear of the second gear of the first motor Gear 9, the driving gear 10 of the first gear of the second mot...

Abstract

The invention belongs to the technical field of hybrid power, and relates to a hybrid power driving system and a vehicle. The hybrid power driving system comprises an engine, a first motor, a second motor, a connection and disconnection unit and a transmission, the first motor and the engine are coaxially arranged, and the second motor and the engine are arranged side by side; and the transmissioncomprises a first shaft, a second shaft, a third shaft, a first synchronizer, a second synchronizer, a first motor first gear driving gear, a first motor second gear driving gear, a second motor first gear driving gear, a second motor second gear driving gear, a first gear driven gear, a second gear driven gear, a main reduction driving gear and a main reduction driven gear. According to the hybrid power driving system and the vehicle, when the system shifts gears, the rotating speed of the first motor or the second motor is controlled to be close to the same as the rotating speed of the target gear, then the first synchronizer or the second synchronizer is connected with the target gear, and the impact feeling in the gear shifting process is relieved.

Description

technical field [0001] The invention belongs to the technical field of hybrid power, and in particular relates to a hybrid power driving system and a vehicle. Background technique [0002] Hybrid systems can improve vehicle fuel economy in several ways. For example, the engine can be switched off during idling, deceleration or braking, driving in pure electric drive mode to eliminate efficiency losses due to engine drag. In addition, the energy stored in the power battery generated by regenerative braking or generated by the electric motor during engine operation can be utilized in pure electric drive mode, or supplement the engine's torque or power in hybrid drive mode. [0003] Hybrid vehicles can be driven by combining at least two different power sources. At present, most hybrid vehicles use a gasoline-electric hybrid system, which includes an engine powered by fuel and an electric motor driven by electricity. In order to improve the combustion efficiency of the engine...
