1轮胎压力监测系统的作用、组成及原理
轮胎压力监测系统(TPMS)监测所有轮胎的气压,并向驾驶人提供任一轮胎是否中度充气不足的信息,或在任一轮胎明显充气不足时向驾驶人发出警告。轮胎压力监测系统也向驾驶人提供任一轮胎是否充气过度的信息,或给定的车桥上左右轮胎之间的气压有很大偏差的信息。轮胎压力监测系统大大提高了车辆的行驶安全性。 相似文献

汽车轮胎气压电子实时监测系统 总被引:9,自引:0,他引:9
轮胎气压不足,将增大轮胎的弯曲变形,加快轮胎的磨损,增大车轮的滚动摩擦阻力,从而导致油耗显著增加,特别是当汽车高速行驶时,更会削弱轮胎的承载能力,导致轮胎破裂漏气。以北美市场及德国BERU公司的产品为例,介绍了轮胎压力电子实时监测系统的技术和市场方面的最新发展趋势。 相似文献

不同宽度轮辋对轮胎静刚度特性影响的试验分析 总被引:1,自引:0,他引:1
针对同一轮胎(205/55R16)安装不同宽度轮辋(6J,61/2J)进行了静态试验研究,分析比较了不同宽度轮辋对轮胎静力学特性的影响。试验结果表明,宽轮辋轮胎的垂直刚度、侧向刚度和纵向刚度均高于窄轮辋轮胎的相应值;而窄轮辋轮胎的扭转刚度大于宽轮辋轮胎的扭转刚度。 相似文献

This paper presents a survey of the state-of-the-art in predicting the wheel vibrations in a complex dynamic vehicle suspension system and their influence on the forces transduced in a high frequency area from the tire to the vehicle's body. Secondly it presents also the transient evolution of tire models used for prediction and understanding high frequency movements in the tire's contact area, producing the guiding forces and torques during vehicle handling. 相似文献

影响轮胎寿命和性能的因素很多,但胎压和负荷可以称得上是轮胎的2大命门。如果胎压或负荷不合适,不仅会大大缩短轮胎的使用寿命,甚至会产生一系列危及人们生命的安全问题。胎压——不容忽视的轮胎命门胎压是轮胎最不容忽视的命门,过高或过低都会缩短轮胎的使用寿命。如果胎压过低,不仅胎侧反复屈挠,容易发生爆裂,而且红色部位磨损快,降 相似文献

An optical tire contact pressure test bench developed by the IMMa group is described. The measurement system is based on the frustration of total internal reflection (FTIR) of light. The test bench allows performing normal pressure distribution and patch contact shape measurements on passenger car tires. The system is based on the use of a laterally illuminated glass on which the tire leans. Between them a plastic interphase is located that will cause the FTIR of light. A video camera catches the formed shining image through the glass. The brightness level in each pixel of the image can be related to the existing normal pressure. The study of the contact patch provided by the bench makes it possible to characterize tire behaviour under different loading states, inflation pressure, tire defects and toe and camber angles. The bench incorporates a computerized load and control system of the tire operation parameters, an image acquisition module and a data acquisition system that allow monitoring and acting on the experimental variables of interest in the tests such as load on the tire and environmental conditions. A supporting mechanical system incorporated to the bench allows providing the tire with variable toe and camber angles. From the images obtained with this system, the maximum normal pressure points, total force, size and shape of the patch can be determined, which are related to the tire-use conditions. As an application example, results that show the patch size and shape under different load and tire inflation pressures are presented. A further application, which is the use of the system for the detection and study of defective tires is also presented. 相似文献
