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
Running gas tire can still continue to run safely after a long distance of the tire said running gas or tire tire. From the structure, run-gas tire can be divided into self-styled and rigid support two categories. Self-sealing is in the tire cavity or sealing layer pre-filled with sufficient sealant, the tire was pierced by foreign objects, the sealant automatically flows to the perforation, blocking the hole, so as to maintain normal driving conditions. Rigid support gas-run tire is divided into self-supporting type and adduct support type two. Self-support type is to increase the original tire on a certain part of the original, so that the tire pressure loss to maintain the driving profile, such as the side reinforcement, triangular cross-section and so on; Adduct support type is through the ordinary tires to increase the parts, Tire pressure to maintain after driving
