However, in this drive system, more clutches and first brakes are required to achieve torque coupling and rotational speed; and when the power source is a hybrid system combining an engine and an electric motor, it requires more clutches and brakes to achieve Pure electric mode, idling start-stop mode, driving assist mode, driving charging mode, engine independent driving mode, regenerative braking mode and other working modes, and the switching operation of each working mode is complicated; therefore, the structure of the hybrid drive system in the prior art It is more complicated, and the transmission efficiency and working reliability of the drive system are low. The transmission shaft adopts the shaft structure with coupling. The structural characteristics of the above products are: the connection strength of the transmission shaft is not high enough, and the transmission efficiency is not high

Description
technical field [0001] The invention relates to a hybrid power coupling system with a flange shaft, in particular to a flange shaft with good impact performance and mechanical performance in the hybrid power coupling system. Background technique [0002] At present, in existing hybrid drive systems with more than two power sources, clutches, first brakes and planetary gear mechanisms are generally used to couple torques and rotational speeds output by different power sources. However, in this drive system, more clutches and first brakes are required to achieve torque coupling and rotational speed; and when the power source is a hybrid system combining an engine and an electric motor, it requires more clutches and brakes to achieve Pure electric mode, idling start-stop mode, driving assist mode, driving charging mode, engine independent driving mode, regenerative braking mode and other working modes, and the switching operation of each working mode is complicated; therefore...
