The invention provides a multi-gear electromechanical coupling transmission system and a vehicle. The multi-gear electromechanical coupling transmission system comprises a motor input shaft, a synchronizer mechanism, a motor intermediate shaft, an engine intermediate shaft, an engine low-gear input shaft and double clutches. According to the technical scheme, gear shifting is achieved at the motor end through the synchronizer mechanism, the synchronizer mechanism is selectively connected with one of the motor low-gear transmission mechanism and the motor high-gear transmission mechanism, and gear shifting is achieved at the engine end through the double clutches. Due to the fact that gear shifting mechanisms of different principles are adopted at the motor end and the engine end, and switching of high gears and low gears can be completed at the two ends of the motor and the two ends of the engine, the output rotating speed and the torque range are greatly increased, and the output speed of the motor and the output torque range are greatly increased. Therefore, the vehicle shows better performance under different working conditions, is beneficial to adapting to complex and harsh scenes such as cross-country abrupt slopes and the like, and also ensures the smoothness and reliability in the gear shifting process.

    本发明提供了一种多挡机电耦合传动系统及车辆,多挡机电耦合传动系统包括:电机输入轴、同步器机构、电机中间轴、发动机中间轴、发动机低挡输入轴和双离合器。应用本发明的技术方案,电机端采用同步器机构实现换挡,同步器机构选择性地与电机低挡传动机构和电机高挡传动机构中的一个接合,发动机端采用双离合器换挡,双离合器的另一端选择性地与发动机低挡输入轴和发动机高挡输入轴中的一个接合,由于电机端和发动机端采取不同原理的换挡机构,并且电机与发动机两端都可完成高低挡的切换,大幅提高了输出的转速及扭矩范围,使得车辆在不同工况下表现出更佳的性能,有利于适应越野陡坡等复杂苛刻场景,也保证了挡位切换过程中的平顺性和可靠性。
