The invention discloses a four-wheel-drive multi-gear hybrid power transmission system which comprises a first drive system and a second drive system which drive two pairs of wheels of a vehicle respectively. Wherein the first driving system comprises an engine, a first motor, an input shaft, a first motor shaft, a first output shaft, a first synchronizer, a second synchronizer and a plurality of gear sets, the input shaft is connected with the engine, the first motor shaft is connected with the first motor, the first synchronizer is connected with the input shaft, and the second synchronizer is connected with the output shaft; matched gear sets are arranged on the input shaft, the first motor shaft and the output shaft to realize transmission connection; the second driving system comprises a second motor, a second motor shaft and a second output shaft. The second motor and the second output shaft are connected directly or through a speed reduction transmission mechanism. According to the system, one motor is omitted, the cost is remarkably reduced, multi-gear switching can be achieved, the fuel consumption economy of an engine is improved, and the system can cope with various working conditions.

    本发明公开一种四驱多挡混合动力传动系统,包括第一驱动系统和第二驱动系统,分别驱动车辆的两对车轮;其中第一驱动系统包括发动机、第一电机、输入轴、第一电机轴、第一输出轴及第一同步器、第二同步器、若干齿轮组,所述的输入轴连接发动机,第一电机轴与第一电机连接,第一同步器连接输入轴,第二同步器连接输出轴,输入轴、第一电机轴、输出轴上设有配合的齿轮组实现传动连接;第二驱动系统包括第二电机、第二电机轴、第二输出轴,第二电机和第二输出轴直接或通过减速传动机构连接。本发明系统减少一个电机,显著降低了成本,且能实现较多挡位切换,提升发动机燃油消耗经济性,能够应对各种工况。
