跑气保用轮胎 漏气后仍能继续安全行驶一段较长路程的轮胎称跑气保用轮胎或零压轮胎。从结构上,跑气保用轮胎可分为自封式和刚性支撑式两大类。自封式是在胎腔或密封层内预先充入足量密封剂,轮胎遭外物刺穿后,密封剂自动流到穿孔处,堵塞洞孔,从而维持正常行驶状态。刚性支撑式跑气保用轮胎又分为自体支撑型和加物支撑型两种。自体支撑型是在普通轮胎上增加原有的某个部件,使轮胎失压后保持行驶轮廓,如胎侧加强型、三角断面型等;加物支撑型是通过增加普通轮胎所没有的部件,达到轮胎失压后保持行驶 相似文献

轮胎是车辆行驶的重要部件,轮胎在出车前、行车中、收车后及车辆保养或修理后的例行检查与保养工作,是驾驶员的日常工作之一,此项工作进行的好坏,直接影响轮胎行驶里程的提高和行驶安全.据有关资料统计,高速公路上46%的交通事故是由于轮胎发生故障引起的.因此,轮胎技术状态的好坏直接影响着车辆行驶的安全和性能,我们千万不要忽视轮胎的例行检查与保养. 相似文献

轮胎的安全性能在很大程度上取决于其抓地能力和稳定性。行驶在冰雪路面,如果使用普通夏季轮胎或全季候轮胎,车辆很容易出现打滑、失控等意外情况,严重威胁到驾驶者和行人的人身安全。2009年11月9日,米其林公司在中国正式发布了第二代米其林XICE冬季轮胎-XICEX12。 相似文献

哈韩派多是追求时尚年轻人,韩剧则是他们的启蒙老师。本人虽不迷这个,但了认可韩剧确有其独特之处。如今,那些涉猎广泛的哈韩派又有了新宠。两年多前,《汽车与运动》曾测试过锦湖ECSTA系列的KU28轮胎。主打舒适节油的它,凭借轻量化的胎身赢得了我们的认可。那时,我就曾翻开字典,试图寻找"ECSTA"的含义,但以失败告终。不过,与其形似的"Ecstasy"却暗示了 相似文献

1汽车轮胎早期磨损的原因
1)轮胎气压不足或超载。轮胎长期在气压不足的情况下行驶,能加速胎体帘线的疲劳损坏,造成外胎爆破。胎壁擦伤,多系双胎并装,因气压不足或超载引起胎侧变形较大,使两胎间接触发生摩擦。 相似文献

SUMMARY This article begins with a brief review of the traditional concept of lateral relaxation length. The review illustrates that this concept yields a useful approximation which can be used with semi-empirical tire models which assume lateral forces are a function of steady-state slip angles. The article then presents an analogous derivation for longitudinal slip. Like its lateral counterpart, the derivation yields an approximation for transient longitudinal slip which can be used with tire models which assume longitudinal forces are a function of steady-state longitudinal slip. It is shown that, like the relaxation-length-based lateral slip angle, this formulation for longitudinal slip yields the ability to compute shear forces at the tire/road interface for either high or low speed applications, a necessary feature of simulations which support human in the loop driving simulation. Like traditional kinematically-based longitudinal slip, the transient formulation presented here is coupled with the wheel spin equation, and it shares the characteristic that it is very stiff compared to the equations of vehicle motion. This characteristic is a challenge impeding the real-time calculations required for driving simulation. The paper shows that local linearization of the wheel spin equations coupled with analytical solutions of the transient longitudinal slip formulation provide the basis for both insight into the longitudinal dynamics of the tire and for integrating the model in real-time. 相似文献
