轮胎气压报警系统能对静止或运动轮胎的气压、温度进行监测,当轮胎气压或温度不满足工作要求时,向驾驶员发出声光报警。轮胎气压报警系统又分轮胎气压监测报警系统和轮胎状态监测报警系统两种类型,为叙述方便,我们将它们统称为轮胎气压报警系统,它是国外各大汽车厂家竞相开发的一个领域。这是因为轮胎气压或温度过高或 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
