Abstract

本发明提供了一种采用非牛顿流体层的轮胎，包括非牛顿流体层、弹性橡胶条和胎面层，非牛顿流体层紧贴胎面层，弹性橡胶条嵌入非牛顿流体层。本发明的有益效果在于：本发明提供了一种采用非牛顿流体层的轮胎，在车辆低速行驶或者静止的时候，胎面和地面的接触面积增大，有利于抓地力的获得；当车辆高速运行的时候，轮胎和地面的接触面积减少，降低了车辆行车轮胎阻力。

Description

一种采用非牛顿流体层的轮胎
技术领域
本发明涉及轮胎技术领域，尤其是指一种采用非牛顿流体层的轮胎。
背景技术
目前轮胎和地面的接触面积主要通过轮胎内部的气压进行调节，胎内气压高，轮胎和地面的接触面积小，胎内气压降低，轮胎和地面的接触面积增大。在车辆行驶过程中，轮胎和地面接触面积大，有利于抓地和制动，但是不利于降低轮胎的阻力；反之，如果轮胎和地面接触面积小，虽然有利于降低轮胎的阻力，但是不利于抓地和制动。由此可见，现有轮胎不能够动态改变轮胎和地面的接触面积。
因此需要一种新型轮胎，可以根据轮胎的转速改变轮胎和地面的接触面积。
发明内容
本发明要解决的技术问题是，现有轮胎不能够动态改变轮胎和地面的接触面积。
为了解决上述技术问题，本发明采用如下技术方法：
一种采用非牛顿流体层的轮胎，包括非牛顿流体层、弹性橡胶条和胎面层，非牛顿流体层紧贴胎面层，弹性橡胶条嵌入非牛顿流体层，非牛顿流体层的材质是非牛顿流体，弹性橡胶条位于靠近轮胎侧面的位置，弹性橡胶条的材质的弹性模量小于胎面层材质的弹性模量，非牛顿流体层的横截面呈扁平形，非牛顿流体层的非牛顿流体的配方为，液态聚乙烯醇30~65重量份，纤维絮状物1~5重量份，纳米碳酸钙15~25重量份，重质碳酸钙10~15重量份，玻璃钎维5~25重量份，非牛顿流体层的横截面宽度的尺寸范围为1毫米到5毫米。
本发明的实现原理是，非牛顿流体具有在高速剪切运动作用下保持原来形状的特性，同时，在低速剪切运动作用下可以变形，将非牛顿流体层紧贴胎面层，起到支撑胎面层的作用，这样，在轮胎低速转动的时候，非牛顿流体层中的非牛顿流体可以流动，致使胎面层下陷，导致胎面层和路面的接触面积增大；当轮胎快速旋转的时候，非牛顿流体层中的非牛顿流体不可以流动，致使胎面层不能下陷，并且使得非牛顿流体层可以直接支撑胎面层，这样胎面层和地面的接触面积减少。弹性橡胶条材质的弹性模量小于胎面层材质的弹性模量，起到吸收形变的作用，在轮胎低速转动的时候，非牛顿流体层的形变压力施加在弹性橡胶条上，使得弹性橡胶条压缩，随着轮胎高速转动，非牛顿流体层的刚性增加，压强刚性直接传递给轮胎内部，此时，弹性橡胶条释放形变，使得轮胎的真圆度增加，也就是说让轮胎在一种更加接近圆形的状态下告诉旋转，降低车辆行驶的阻力。纤维絮状物的形状类似天然棉花团，材质是高分子材料，在轮胎长时间静置的时候，纤维絮状物起到防止其他物质发生沉降的作用。
本发明的有益效果在于：本发明提供了一种采用非牛顿流体层的轮胎，在车辆低速行驶或者静止的时候，胎面和地面的接触面积增大，有利于抓地力的获得；当车辆高速运行的时候，轮胎和地面的接触面积减少，降低了车辆行车轮胎阻力。
