摘　　要：转向支架在客车行驶时的安全性起着举足轻重的作用。转向支架经过有限元技术分析优化后,安装在客车底盘上,在加载1.5 t和加载4.5 t两种工况下进行测试。转向盘分别逆时针左转再顺时针右转,在不同的转角下采集处理转向支架受扭的应变应力。测试结果表明,该客车转向支架强度符合设计要求,同时测试数据为研究转向支架的受力情况提供了有价值的信息。Steering bracket plays a very important role in the bus driving safety. The steering bracket is optimized through the analysis of finite element technology and then it is tested in loading 1.5t and loading 4.5 t for two kinds of working conditions. Steering wheel counterclockwise turn left and clockwise turn fight respectively, in different angle the torsioning swain stress of steering bracket is collected mad processed. Test results show that the strength of bus＇ steering bracket complies with the design requirements, which provide valuable information for the study of steering bracket stress.
