Problems solved by technology

[0004] Apparently, in the hybrid power system with the above structure, on the one hand, the first motor MO1 (GEN) and the second motor MO2 are drivingly coupled with the input shaft and the output shaft of the gear transmission mechanism respectively, thus resulting in a hybrid power system structure On the other hand, there are too few gears (gear ratios) that can be used under the pure motor drive mode and the hybrid drive mode, although there are more gears in the hybrid power system with other structures in the prior art , but the structure is complicated and the torque transmission will be interrupted during the shifting process

Embodiment Construction

[0023] The specific technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the present invention, "transmission coupling" means that driving force / torque can be transmitted between two components.

[0024] (Structure of a hybrid system)

[0025] like figure 2 As shown, a hybrid system according to an embodiment of the present invention includes an engine ICE, a clutch K0, a motor EM, a transmission and a differential DM.

[0026] In the present embodiment, the engine ICE is a four-cylinder engine. However, the engine ICE is not limited to a four-cylinder engine, and may be other types of engines. like figure 2 As shown, the engine ICE is drivingly coupled with the second input shaft S2 of the transmission via the clutch K0. When the clutch K0 is engaged, the transmission connection between the engine ICE and the second input shaft S2 of the transmission is achieved; when t...

Abstract

The invention relates to the field of hybrid vehicles, in particular to a hybrid power system and the hybrid vehicle. The hybrid power system includes a transmission, a motor, an engine and a clutch.The transmission includes a first input shaft, a second input shaft, an output shaft, synchromesh engaging mechanisms and gears. The second input shaft is sleeved with the first input shaft and the first input shaft can be selectively connected to the second input shaft and the output shaft in a transmission mode through a plurality of synchronizing engaging mechanisms and a plurality of gears. Aninput / output shaft of the motor is directly connected to the first input shaft in a coaxial mode. The engine is connected to the second input shaft in a transmission mode through the clutch. In thisway, the hybrid power system achieves the same torque transmission mode as the prior art by only one motor, and thus the structure is simpler; and moreover, the hybrid power system is provided with sufficient gears for both the motor and the engine.

Description

technical field [0001] The present invention relates to the field of hybrid vehicles, and more particularly, the present invention relates to a hybrid system and a hybrid vehicle including the hybrid system. Background technique [0002] like figure 1 As shown, there is a hybrid system including an engine ENG, a first motor MO1 (GEN), a second motor MO2, a battery BAT, a clutch K0 and a gear transmission mechanism. [0003] Specifically, the engine ENG is respectively coupled with the gear transmission mechanism and the first motor MO1 (GEN) through the clutch K0, so that the engine ENG is controlled by the engagement and disengagement of the clutch K0 to drive the first motor MO1 (GEN) to generate electricity to charge the battery BAT , and control the engine ENG to transmit torque to the gear transmission mechanism, and then transmit the torque to the tire TIRE through the gear transmission mechanism. The first motor MO1 (GEN) is directly coupled with the input shaft of ...
