The invention relates to a single motor driving transmission structure and an engineering vehicle, the single motor driving transmission structure comprises an input shaft S-in, a forward gear clutch CF, a reverse gear clutch CR, a first power transmission unit, a second power transmission unit and an output shaft S-out, the first power transmission unit is in transmission connection between the forward gear clutch CF and the output shaft S-out, and the second power transmission unit is in transmission connection between the forward gear clutch CF and the output shaft S-out. The second power transmission unit is in transmission connection between the reverse gear clutch CR and the output shaft S-out, and the input shaft S-in and the output shaft S-out are each provided with a power output end. Single motor driving is adopted, through a transmission and gear shifting structure, hydraulic system operation and chassis running are driven respectively, an independent operation mode and a running-operation mode are achieved, an electric transmission gearbox is not needed, the control and power transmission process is simplified, the energy efficiency ratio is increased, and the advantages of fast response and high control precision of the motor are brought into play; a power battery is used as a power source; the emission is reduced and the environmental protection performance is improved.

    本发明涉及一种单电机驱动传动结构及工程车辆,包括输入轴S‑in、前进挡离合器CF、后退挡离合器CR、第一动力传递单元、第二动力传递单元及输出轴S‑out,第一动力传递单元传动连接在前进挡离合器CF和输出轴S‑out之间,第二动力传递单元传动连接在后退挡离合器CR和输出轴S‑out之间,输入轴S‑in上和输出轴S‑out上分别配置有动力输出端。采用单电机驱动,通过传动及换挡结构,实现液压系统作业和底盘行驶分别驱动,实现单独作业模式和行驶‑作业模式,无需电传动变速箱,简化控制和动力传递流程,提高能效比,发挥电机响应快、控制精度高的优点,采用动力电池作为动力源,降低排放,提高环保性能。
