The main function of the solid tire pattern of the self feeding mixer is to increase the friction between the tread and the road surface, so as to prevent the wheel slipping of the self feeding mixer, which is the same as the sole pattern. The solid tread pattern of the self loading mixer improves the contact elasticity of the tread. The tread pattern can produce large tangential elastic deformation under the action of tangential forces (such as driving force, braking force and lateral force) between the tread and the road surface.

切向力增加，切向变形就随之增大，接触面的“磨擦作用”也就随之的增强，所以抑制了自上料搅拌车胎面和路面打滑或着打滑趋势。

With the increase of tangential force, the tangential deformation increases, and the "friction effect" of the contact surface also increases, so the skid or slipping trend of the self loading mixer tread and road surface is restrained.

这在很大程度上，面了无花纹(光胎面)轮胎容易打滑的弊病，使得与轮胎和路面间磨擦性能有关的汽车性能——动力性、制动性、转向操纵性和行驶性的正常发挥有了可靠的保障。

To a great extent, the tread eliminates the slip of the tread free (smooth tread) tire, and ensures the normal performance of the vehicle, which is related to the friction performance between the tire and the road, such as power performance, braking performance, steering maneuverability and driving safety.

有研究表明，中科自上料搅拌车产生胎面和路面间磨擦力的因素还包括有这两面间的粘着作用，分子引力作用以及路面小尺寸微凸体对胎面微切削作用等，但是，起主要作用的仍是花纹块的弹性变形。

Studies have shown that the friction force between the tread and the road surface of Zhongke self loading mixer also includes the adhesion between the two sides, the molecular gravity and the micro cutting effect of small-size bumps on the tread. However, the elastic deformation of the tread block still plays a major role.
