A single-clutch double-gear low-cost hybrid power system comprises a power input end and a power output end, the power input end is provided with a first power source, and the hybrid power system further comprises a first epicyclic gear train, a second epicyclic gear train, a first brake and a second brake. According to the hybrid power system designed by the invention, one motor and two planet rows are adopted, and the two planet rows share one gear ring, so that the hybrid power system is simple in structure, convenient to machine and low in cost; in the whole structure, only one clutch is adopted to be matched with other gear structures to realize two different gears, namely a low gear and a high gear, of a heavy-duty dump truck, and the cost is low; and the characteristics of the engine and the motor and speed change of the two-stage planetary gear are utilized, so that the optimal performance suitable for the heavy dump truck is achieved.
一种单离合器双档位低成本混合动力系统,包括动力输入端和动力输出端,所述动力输入端设置有第一动力源,该混合动力系统还包括第一周转轮系、第二周转轮系、第一制动器和第二制动器。本发明设计的混合动力系统,采用一个电机和两个行星排,而且两个行星排共用一个齿圈,结构简单,便于加工,成本低;整个架构中仅采用一个离合器配合其他齿轮结构实现了重型自卸车的两个不同档位,低速档和高速档,成本低;利用发动机与电机各自的特点,以及二级行星齿轮的变速,达到了适合此类重型自卸车的最优性能。
