Large-tonnage independently-driven single-steel-wheel road roller
The invention relates to the technical field of road roller control, and particularly discloses a large-tonnage independently-driven single-steel-wheel road roller which comprises a bottom frame and a hydraulic walking system arranged on the bottom frame, and the hydraulic walking system comprises a front walking pump, a rear walking pump, a steel wheel motor, an axle drive motor and two electromagnetic valves; an oil outlet of the front walking pump is connected with an oil inlet of the steel wheel motor; an oil outlet of the steel wheel motor is connected with an oil inlet of the front walking pump; an oil outlet of the rear walking pump is connected with an oil inlet of the bridge drive motor; an oil outlet of the axle drive motor is connected with an oil inlet of the rear walking pump; an oil outlet of the front walking pump is connected with an oil outlet of the rear walking pump through an electromagnetic valve; an oil inlet of the front walking pump is connected with an oil inlet of the rear walking pump through an electromagnetic valve. Compared with the prior art, the front steel wheel and the driving wheel can be independently driven, and the driving capacity is enhanced; and under the condition of inconsistent current loads or reverse dragging, the pressure balance of the front steel wheel and the driving wheel can be realized.
本发明涉及压路机控制技术领域，具体公开了一种大吨位独立驱动单钢轮压路机，包括底架和设置在底架上的液压行走系统，所述液压行走系统包括前行走泵、后行走泵、钢轮马达、桥驱马达和两件电磁阀；所述前行走泵的出油口连接钢轮马达的进油口；所述钢轮马达的出油口连接前行走泵的进油口；所述后行走泵的出油口连接桥驱马达的进油口；所述桥驱马达的出油口连接后行走泵的进油口；所述前行走泵的出油口通过电磁阀连接后行走泵的出油口；所述前行走泵的进油口通过电磁阀连接后行走泵的进油口。与现有技术相比，前钢轮和驱动轮能够独立驱动，增强驱动能力；当前负载不一致或者出现反拖情况下，能够实现前钢轮和驱动轮压力平衡。
