一种混合动力拖拉机用驱动系统
By using a series hybrid power system that independently drives the front and rear axles with two electric motors, combined with a normally engaged clutch and planetary gear mechanism, the problems of unequal drive wheel slip rates and insufficient braking capacity of hybrid tractors are solved, thereby improving traction efficiency and overall machine stability and adapting to different operational needs.
