三、牵引附着系数履带式机器在行驶过程中,履带接地区段便产生与机器行驶方向相反的运动趋势,但由于同地面的作用而被阻止。此时来自地面的反作用力直接作用在履带接地区段上。机器克服地面水平阻力所用的力,称为机器的驱动力。该力的大小受地面附着条件制约。履带对地面的附着力包含:机器行驶时接地履带板与地面之间的摩擦力,接地履带板的履刺压入地面内
Third, the traction adhesion coefficient Track-type machine in the driving process, the track grounding section will produce a movement in the opposite direction of the trend of the machine, but due to the same role as the ground was blocked. At this time, the reaction force from the ground acts directly on the track grounding section. The force that the machine uses to overcome the horizontal resistance of the ground is called the driving force of the machine. The size of this force is limited by the conditions of the ground attachment. Adhesion of the track to the ground includes the friction between the grounded track shoe and the ground when the machine is running, and the traction of the ground track shoe presses into the ground.
