一种车用射流发射器阀座设计 摘要 据统计，我国每年死于交通事故人数以超过十万人。其中，高速公路上发生的重大交通事故，有70%是由于爆胎引起的。因此导致的车毁人亡，占高速公路意外事故死亡人数的49.81%，被公认为高速行车安全的头号杀手。如何高效的防护轮胎也成为了一个正待解决的问题。在传统的被动防护的基础上，车用射流发射器采用了主动防护的方法，在汽车上加装高压水射流装置，能够有效清除道路上的微小尖锐物，从而有效的保证了行车安全。在轮胎主动防护装置这一系统中，射流器阀座的设计起着至关重要的作用。在本文中，重点探讨了车载射流发射器这一轮胎主动防护装置中发射器阀座的设计，完善了射流器的设计可以使喷头准确对准目标物，提高装置对微小尖锐物的清除效率，有效保护了轮胎。其中包括阀座动力源的选择及设计，及阀座伺服系统的选择使其满足一定的随动性及自适应性。本设计选用了伺服系统的模块化来设计阀座，通过对伺服系统的受控体、制动器、控制器的分别设计来构成了整个阀座模块的设计，本设计使车用射流发射器更加完善，研究结果为汽车轮胎主动防护装置的工业设计提供可靠的理论基础。 关键词：伺服系统，阀座，自适应性 A vehicle jet emitter valve seat design ABSTRACT According to statistics, the number of accidents in China every year to more than one hundred thousand people. Among them, the serious traffic accident on the expressway, 70% is due to cause a tire blowout, so lead to car crash, 49.81% accounted for Expressway accident deaths, is recognized as the number one killer of high-speed traffic safety. How to protect the tire also becomes a problem to be solved.. On the basis of traditional passive protection, car jet transmitter for the active protection, installation of high pressure water jet device in the car, can effectively remove on the way to the small sharp objects, so as to effectively guarantee the safety of driving. The design of the transmitter valve seat is the focus of the whole vehicle jet launcher. Including design of power source of the hydraulic pump; improve energy storage components, hydraulic cylinder, relief valve, an electromagnetic valve, a relay design; complete the seat design; the jet transmitter meet certain adaptive, vehicle speed, and the emission intensity of requirements. The design of the car with the jet emitter valve seat is more perfect, the results of the car tire active protection device for industrial design.
