摘　　要：在推土机作业过程中，急剧变化的外部阻力常常会使发动机转速下降或者使机器滑转率上升，进而导致整机工作状况恶化。本文提出了一种推土机极限荷载自动控制系统，该系统可以根据机器的工作状态自动调整铲刀的切削深度，从而保证推土机始终工作于生产率最高的状态。During the operation of a bulldozer, rapidly changing external resistance results in the decrease of engine speed and the increase of slip, as well as worse working situation. An automatic control system for load limit of bulldozer is suggested in the article. By this system, the cutting depth of blade can be adjusted automatically according to the working conditions of the machine so to assure that the bulldozer is always working with highest productivity.
