Such preparations and less investment, start-up fast high production efficiency, over easy.The driver of the tractor is main differential thing, it will power to the wheels, and at the same time, allowing two round as different wheel rotation. And meet the pure rolling on both sides as far as possible and the form of uniform of the road, reduce the friction of the tires and the ground.Keywords: differential mechanism process tractor 目录摘 要.................................................................................................................................................IAbstract............................................................................................................................................II第 1 章绪论............................
