履带式推土机通常采用手脚联动油门操纵机构。驾驶员启动推土机发动机后,用手动油门设定发动机的最大转速并进行锁止。推土机作业时,用脚踩油门进行发动机转速的微调。发动机转速在手动油门设定范围内,脚踩力度越大,发动机转速越低。抬脚后,发动机转速恢复到手动油门设的最大转速。1.存在问题目前,大多数履带式推土机手脚联动油门
Crawler tractors are usually operated by hand and foot throttle linkage. After the driver starts the bulldozer engine, set the maximum engine speed with the manual throttle and lock it. Doing a bulldozer operation, the accelerator pedal speed engine fine-tuning. Engine speed in the manual throttle setting range, the greater the footwork, the lower the engine speed. After raising the foot, the engine speed is restored to the maximum speed of the manual throttle setting. 1. Existing problems At present, most crawler tractors hand and foot linkage accelerator
