The invention relates to the technical field of engineering machinery, in particular to a road roller walking system and a walking control method. The road roller walking system comprises a frame, a variable pump, a left walking motor, a right walking motor, an oil supplementing pump and a controller, wherein a motor is arranged on the frame; the variable pump communicates with a hydraulic oil tank and is in transmission connection with the motor; an oil inlet of the left walking motor communicates with a high-pressure oil outlet of the variable pump, an oil return port of the left walking motor communicates with a low-pressure oil return port of the variable pump, and the left walking motor is in transmission connection with a left walking system ; an oil outlet of the oil supplementing pump communicates with a control port of the variable pump, a control port of the left walking motor and a control port of the right walking motor; and the controller is electrically connected with themotor. According to the road roller walking system, stepless speed change control can be realized when the road roller walking system walks without using a hydraulic torque converter or a gearbox.
本发明涉及工程机械技术领域，尤其涉及一种压路机行走系统及行走控制方法，压路机行走系统包括车架，于所述车架上设置有电机；变量泵，所述变量泵与液压油箱连通，且与所述电机传动连接；左行走马达，所述左行走马达的进油口与所述变量泵的高压出油口连通，所述左行走马达的回油口与所述变量泵的低压回油口连通，所述左行走马达与左行走系统传动连接；右行走马达；补油泵，所述补油泵的出油口与所述变量泵的控制口、所述左行走马达的控制口和所述右行走马达的控制口均连通；控制器，与所述电机电连接。本发明能够无需使用液力变矩器和变速箱即可在压路机行走系统行走时实现无级变速控制。
