中央轮胎充放气系统(CTIS)是在车辆行驶过程中,对各个轮胎进行实时充气和放气的气压调节装置.由于越野汽车经常行驶的道路状况比普通汽车复杂得多,沙地、急造军路等软路面需要降低轮胎气压以增加对路面的附着力,而在普通柏油或水泥路面上需要提高轮胎气压以减少滚动阻力.车轮中央充放气系统能使驾驶员在规定范围内改变轮胎气压.在不同的地面和气候条件下,分别或同时调整前轮、后轮的胎压,使车辆具有最大附着力和灵活性,以适应各种不同的路面条件和气候情况,提高汽车的通过能力.所以,中央轮胎充放气系统成为越来越多越野汽车的标准配置. 相似文献

在维修涉及无线电发射系统或原件的故障时,一定要注意更换的新配件与原件发射频率是否一致,匹配时有无相同的外界频率干扰。一辆08年款保时捷卡宴GTS,配置4.8排量越野型超级跑车,底盘号为WP1AD29P78LA73##,行驶了126621km,现在轮胎气压监控系统灯报警其它功能均使用正常。这款保时捷使用了四轮带发射天线直接式TPM(轮胎气压监控系统)监控系统,它是一款非常精准的胎压监控系统。故障现象客户反映,几天前车子在行驶中轮胎气压灯亮了,测量轮胎气压,结果显示气压正常。之后不知何原因, 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
