Truck Wheel Fastener Alarm Systems for the Prevention of Runaway Wheels

运输卡车的车轮脱落是非常危险的，经常是致命的。车轮逃逸归因于两个问题：1。2.车轮螺柱失效；轴承失效/过热。高速公路上大量的卡车和拖车使问题更加严重。根据省记录，70%的故障是由于螺柱失去扭矩造成的。我们建议开发两种不同的解决方案，以防止卡车车轮在操作过程中逃逸，从而消除道路危险，即通常是致命的。第一种解决方案使用预先校准的车轮螺柱，这种螺柱内置开关，可以在预定的螺柱伸长时激活，并向车辆操作员发送信号，表明特定的耳钉扭矩不足、扭矩过大或剪切。第二种解决方案是在凸耳螺母下方使用低杨氏模量材料的压缩环，在预定的预载荷下压缩和关闭开关，并在出现不希望的扭矩水平时发出信号。这两个系统都可以通过GPS从远程位置进行监控。这两种解决方案需要渗透到整个市场，并解决车轮问题。第一个解决方案处理的是已经存在的大量卡车和拖车，目前正在道路上行驶。需要一种廉价且易于安装的解决方案来快速将这些车辆转换为安全的行驶单元。第二种解决方案适用于新设备，其中系统可以在原始组装期间轻松安装。

Escaped wheels from Transport Trucks is a highly dangerous, often fatal occurrence. Wheel escapes are attributed to two issues:1. The failure of wheel studs and 2. Bearing failure/over heat. The problem is exacerbated by the large number of trucks andtrailers on the highways. According to provincial records, 70% of failures are due to studs losing torque.We propose the development of two separate solutions that prevent truck wheels from escaping during operation therebyeliminating a road hazard, i.e., oftentimes fatal. The first solution uses pre-calibrated wheel studs which are studs that have built in switches that activate at a predetermined stud elongation and cause a signal to be sent to the vehicle operator that a specific Lug Stud is either under torqued, over-torqued or sheared. The second solution is a compression ring that uses low Young's modulus material below the lug nut to compress and close a switch at a predetermined pre-load and cause a signal to be sent when an undesirable torque level is present. Both systems can be monitored by GPS from remote locations.The two solutions are required to penetrate the complete market and resolve the wheels issue. The first solution deals with thelarge number of trucks and trailers that already exist and are presently on the roads today. An inexpensive and easy to installsolution is required to quickly convert these vehicles into safe travelling units. The second solution is for new equipment wherein the system may be facilely installed during original assembly.
