汽车液压动力转向器台架试验方法研究

以汽车齿轮齿条液压动力转向器为例,针对该总成空载转动力矩试验、转向力特性试验、逆向疲劳试验、正转耐久试验、温度交变密封试验和噪声试验等6个项目的台架试验方法进行了研究,阐述了各项目的试验目的、试验方法和结果、试验设备的配置及与现有试验标准的差别等,为修订汽车动力转向器行业标准提供了参考和依据.

Study on Bench Test Method of Automotive Hydraulic Power Steering Gear

The article takes the rack and pinion hydraulic power steering gear as example and studies the bench test method of six items including empty loaded driving moment test,steering force characteristics test,reverse fatigue test,positive rotation durability test,temperature alternation seal test and noise test,etc.Test objectives,test method and results,test equipment configuration as well as difference with the existing test standard are discussed,which provide reference and foundation for revising the standard of automotive power steering gear industry.
