| 摘 要： | 近年来,农用车辆特别是拖拉机对环境和资源造成的压力逐年增大,开展节能环保拖拉机特别是混合动力拖拉机的研发已成为迫在眉睫的重要课题,而动力耦合装置是混合动力拖拉机的核心。该文根据拖拉机工作特性和传动特性要求,对混合动力拖拉机动力耦合装置传动比、特征参数和齿数匹配等进行了设计。根据传动载荷需求和制造工艺要求进行了结构设计和强度校核,研制了适用于并联式混合动力拖拉机的动力耦合装置。在自行搭建的混合动力拖拉机试验台上对该耦合装置进行了测试。试验结果表明,该装置能够满足拖拉机工作状态下的工作特性要求,输出端转速对动力源的转速变化很敏感,实时变化性能优,而输出端转矩对动力源转速变化不敏感。该耦合装置的研制为混合动力拖拉机的研发提供了基础。

| Abstract: | In recent years, effects of agricultural vehicles, especially tractors on the environment and resources are increasing year by year, so carrying out the research and development of energy-conservation and environmental protection tractors, especially hybrid electric tractors has become the imminent important subject. And the power coupling is the core of hybrid electric drive system. According to the requirements of working properties and transmission characteristics of tractors, the transmission ratio, characteristic parameters and matching number of gear teeth of power coupling device for hybrid electric tractor were designed. Based on the requirement of transmission load and manufacturing technology, the structure design and strength check were processed. Then a new power coupling for parallel hybrid electric tractor was developed, which was also tested on self-developed hybrid electric tractor test-bed. The results showed that the power coupling device can meet the needs of working characteristic under working condition. In addition, the output speeds were sensitive with the speed changes of power sources, and had excellent ability in real-time speed changing while the output torque was insensitive with the speed changes of power sources. The development of power coupling device provides the foundation for further research on hybrid electric tractors. |
