【摘要】：随着治理超限超载运输工作的持续深入，以及高速公路计重收费的全面推广，双前桥转向货车这一既满足政策法规要求，又符合运输业户需求的车型，适应了市场发展，获得了市场认可，销量连年激增，在高速公路上的应用越来越多。本文通过对2006年至2011年全国高速公路货车运输量的调查统计，得到了双前桥转向货车在我国高速公路上的使用状况。双前桥转向货车在我国高速公路网交通流中的份额越来越大。通过对2005年至2011年我国各轴型货车销售情况的统计分析，得到了双前桥转向货车市场的变化情况。通过对治理超限超载运输政策的跟踪以及对计重收费指导意见的理解，，探讨了治理超限超载运输工作和高速公路计重收费政策对我国双前桥转向货车市场拓展的推动机理。双前桥转向货车在使用过程中存在轮胎异常磨损、方向盘抖动、轮胎摆振等问题。本文在介绍了双前桥转向货车转向系统结构及其转向原理的基础上，对车轮各定位参数进行了分析，给出了双前桥转向货车轮胎异常磨损的特点，讨论了影响轮胎异常磨损的设计、制造因素以及使用因素，给出了相应的改进措施。此外，本文探讨了双前桥转向货车转向轮摆振问题及其产生机理，从结构和设计两个方面提出了解决方法。
[Abstract]:With the continuous deepening of the management of over-limited and overloaded transportation, and the overall promotion of weight-bearing tolls on expressways, the double-front axle turning to freight cars, which not only meets the requirements of policies and regulations, but also meets the needs of the transport industry, has adapted to the development of the market. Has won the market recognition, the sales volume surges year after year, the application on the highway is more and more. Based on the investigation and statistics of the freight car volume of national expressway from 2006 to 2011, the usage of the double-front axle steering truck on the highway in our country is obtained in this paper. The double-front-axle steering truck plays an increasingly important role in the traffic flow of the highway network in China. Through the statistical analysis of the sales situation of each axle truck in China from 2005 to 2011, the change of the double front axle steering truck market is obtained. Based on the follow-up of the overloading transportation policy and the understanding of the guiding opinions on the weight charge, this paper discusses the driving mechanism of the control of the overloading transportation work and the weight-weighing toll policy of the expressway to the expansion of the market of the double-front-axle steering truck in our country. There are some problems such as tire wear, steering wheel jitter, tire shimmy and so on in the operation of double front axle steering truck. Based on the introduction of the steering system structure and steering principle of the double front axle steering truck, the positioning parameters of the wheel are analyzed, and the characteristics of abnormal wear and tear of the tire of the double front axle steering truck are given. The design, manufacture and application factors of abnormal wear and tear of tire are discussed, and the corresponding improvement measures are given. In addition, the problem of steering wheel shimmy of double-axle steering truck and its generating mechanism are discussed in this paper, and the solution is put forward from two aspects of structure and design.
