轮胎花纹深度对电动叉车有影响吗?

来源:/ 日期:2020-03-19 发布人:admin

  轮胎花纹愈深,则花纹块接地弹性变形量愈大,由轮胎弹性迟滞损失形成的滚动阻力也将随之增加。较深的花纹不利于轮胎散热,使胎温上升加快,花纹根部因受力严惩而易撕裂、脱落等。花纹过浅不仅影响其贮水、排水能力,容易产生有害的“滑水现象”,而且使光胎面轮胎易打滑的弊端凸现出来,从而使前面提及的汽车性能变坏。

  The deeper the tread pattern is, the larger the elastic deformation of the tread block is, and the rolling resistance caused by the elastic hysteresis loss of the tire will increase accordingly. The deeper tread is not conducive to the heat dissipation of the tire, accelerating the rise of tire temperature, and the root of the tread is easy to tear and fall off due to severe stress. Too shallow tread pattern not only affects its water storage and drainage capacity, and is easy to produce harmful "water sliding phenomenon", but also causes the defects of smooth tread tire easy to slip, which makes the car performance mentioned earlier worse.

  因此,轮胎花纹过深过浅都不好。客观规律是使用中花纹将越变越小。为了确保花纹作用的有效性,世界各国都对轮胎花纹磨损极限制定了明确的法规。并在轮胎胎肩沿圆周的若干等份处模刻轮胎磨耗极限警报标记“”或(和)“TWI”英文标记。当花纹块凸面磨损距离到花纹沟槽底部约1.6mm(1/16英寸)时,标记处的花纹已被磨平,故显露出窄横条状的光胎面,借此警示驾驶员,该轮胎已到了必须更换的时候了。
  Therefore, it's not good to have too deep or too light tread patterns. The objective rule is that the pattern will be smaller and smaller in use. In order to ensure the effectiveness of tread pattern, countries all over the world have made clear regulations on the wear limit of tread pattern. The warning mark "" or (and) "twi" in English shall be engraved on several equal parts of the tire shoulder along the circumference. When the wear distance from the convex surface of the pattern block to the bottom of the groove is about 1.6mm (1 / 16 inch), the pattern at the mark has been ground flat, so a narrow strip of smooth tread is exposed, which warns the driver that the tire must be replaced.
