摘要：为了制定轿车轮毂轴承耐久性试验的载荷谱，在建立轿车动力学模型的基础上，分析了轿车轮毂轴承受载的情况。根据实际轿车的一般行驶状态，制定出了轿车行驶的循环周期，基于我国路况特点，确定出了在每个循环周期内每种行驶状态所占的比例。针对一个周期内不同行驶状态轮胎所受的力不同，从而制定了轮毂轴承的试验载荷谱，分析结果表明，该方法对轮毂轴承加载方式的研究具有指导意义。

Abstract: Aiming at setting out the endurance test load rule of wheel bearing, On the basis of establishing the dynamic model, the load situation of the wheel bearing was analyzed. According to the ordinary transport conditions of the actual car, the steering cycle of the car was set up. At the same time, according to the road conditions of our country, the fixed proportion what every transport condition occupied in a cycle was defined. In a cycle, the different transport conditions makes the tires undertake different loads. Through it, the test load rule of wheel bearing was set out. The analysis results show that it has the guiding significance to the study from the loading way of wheel bearing.
Key words: wheel bearing; lateral acceleration; probability of the lateral adherence; load rule
