The invention relates to the technical field of tractor power control, in particular to a tractor hybrid power system and a tractor, the tractor hybrid power system comprises a driving device, a speed change device, a rear axle wheel end driving device and a PTO, the driving device is used for providing driving force for a whole vehicle, and the speed change device is used for achieving tractor starting and sectional type stepless speed change; the rear axle wheel end driving device is used for driving rear wheels of the tractor; and the PTO is used for taking off the driving force and driving a cultivation tool assembled on a tractor. Double output of driving force is achieved through the arrangement of the hybrid engine and the motors in the driving device, compared with a traditional double-motor hybrid power system, the space utilization rate is higher, and for a high-horsepower tractor with the high power requirement of 100 horsepower or above, the high-power hybrid power system has the advantages of being excellent in power performance, better in oil saving performance, higher in reliability, lower in cost, more compact in space and capable of being widely applied to high-power tractors with the high power requirement of 100 horsepower or above. The operation is more convenient; the problems that a tractor hybrid power system is urgent in spatial arrangement, complex in structure and low in reliability are solved.
本发明涉及拖拉机动力控制技术领域,具体为一种拖拉机混合动力系统及拖拉机,包括驱动装置、变速装置、后桥轮端驱动装置以及PTO,所述驱动装置用于为整车提供驱动力,所述变速装置用于实现拖拉机启动及分段式无级变速;所述后桥轮端驱动装置用于实现拖拉机后轮驱动;所述PTO用于对驱动力进行取力,并驱动拖拉机装配的耕具。通过驱动装置中的混合发动机和电机的设置实现驱动力的双输出,与传统双电机混动系统相比,空间利用更率高,对于功率需求较大的100马力以上的大马力拖拉机,具有优异的动力性能,节油性能更好,可靠性更高,同时成本更低,空间更为紧凑,操作更为方便;解决拖拉机混合动力系统空间布置紧迫,结构复杂,可靠性低的问题。
