Hybrid powertrain and hybrid vehicle

Abstract

The invention relates to the field of hybrid vehicles, in particular to a hybrid powertrain and a hybrid vehicle. The hybrid powertrain comprises a motor transmission module and an engine, wherein themotor transmission module comprises a motor and a transmission; the motor is selectively in transmission connection with an input shaft or an output shaft of the transmission through a multistage gear transmission mechanism; and the engine is transmission connection with the input shaft of the transmission through a clutch in the transmission. By adopting the technical solution, the novel hybridpowertrain disclosed by the invention integrates the motor and the transmission into one module, and the motor can be selectively in transmission connection with the input shaft or the output shaft ofthe transmission through the multistage gear transmission mechanism. Therefore, compared with a conventional powertrain structure, the hybrid powertrain disclosed by the invention does not change much, and the torque of the motor can change torque output modes through the selective transmission connection so as to increase the torque output modes of the motor.

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] In prior art hybrid systems, such as figure 1 As shown, there is a hybrid system including an electric motor EM, an engine ICE, a transmission and a differential DM. [0003] The transmission includes an input shaft S11, an output shaft S12, and an intermediate shaft S13 arranged parallel to each other and spaced apart. Four synchronous meshing mechanisms A11, A12, A13, A14 and multiple gears corresponding to these synchronous meshing mechanisms A11, A12, A13, A14 are arranged on the input shaft S11, output shaft S12 and intermediate shaft S13. The device DM is only in transmission connection with the output shaft S12. Further, the input shaft S11 of the transmission is provided with a clutch K10, through which the clutch K10 can be coupl...

Problems solved by technology

[0004] In this way, in the hybrid system with the above-mentioned structure, since the structures of the synchronous meshing mechanisms A11, A12, A13, A14 of the shift mechanism of the transmission and the gear gears adopt unconventional settings, the structure of the transmission is relatively different from the conventional The structural change of the transmission is very large, making the structure too complicated; and no matter by engaging the synchromesh mechanism A13 with the corresponding gear or by engaging the synchromesh mechanism A14 with the corresponding gear, the torque of the motor EM can only be transmitted through the output shaft S12 output, which limits the torque output mode of the motor EM
