Dual-power walking driving system and snow sweeper
The invention discloses a dual-power walking driving system; a transmission shaft extends to a front axle and a rear axle respectively and can transmit to the front axle and the rear axle at the same time; the transmission shaft is sequentially provided with a hydraulic transfer case and a variable speed transfer case in the axial direction; and the hydraulic transfer case and the variable speed transfer case can independently control transmission and disconnection with the transmission shaft and can independently drive the transmission shaft to rotate so as to drive the front axle and the rear axle. Power output by the gearbox drives the transmission shaft through the variable speed transfer case, and power output by the hydraulic motor drives the transmission shaft through the hydraulic transfer case. In the normal walking state, the engine drives the transmission shaft through the gearbox; and in the low-speed operation state of snow removal operation, the hydraulic motor drives the transmission shaft through the hydraulic transfer case, so that low-speed operation is achieved; and the snow sweeper adopts different walking driving modes according to different states, and therefore the low-speed operation requirement of the snow removal working state of the snow sweeper is met. The snow sweeper can achieve the same technical effect.
本发明公开一种双动力行走驱动系统，传动轴分别向前桥和后桥延伸，能够同时向前桥和后桥传动；传动轴沿轴向依次设置液压分动箱和变速分动箱；液压分动箱和变速分动箱能够分别独立地控制与传动轴的传动与断开，并可以独立地带动传动轴旋转，进而驱动前桥与后桥。变速箱输出的动力经由变速分动箱驱动传动轴，液压马达输出的动力经由液压分动箱驱动传动轴；在正常行走状态，由发动机经由变速箱驱动传动轴，在除雪作业的低速运行状态，液压马达经由液压分动箱驱动传动轴，以实现低速运行，除雪车针对不同的状态采用不同的行走驱动方式，从而满足除雪车除雪工作状态的低速运行需求。本发明的除雪车可达到相同的技术效果。
