RD11型橡胶缓冲器是日本客车主型缓冲器。近年来,对其缓冲性能进行了调查。方法是从1966年至1978年装车运用试验的缓冲器中任意抽样,进行缓冲性能试验。现将调查结果及劣化判定标准介绍如下: 一、缓冲性能调查结果 1.外观状态经过3年以上运用的缓冲器,胶片表面有无数细小裂纹,褪色严重,形成白泡状态,即产生了臭氧老化。经过13年以上运用的缓冲器,胶片的橡胶与连接板之间产生开裂,一加载荷便呈明显开口状态。
RD11 rubber buffer is Japan bus main buffer. In recent years, its buffer performance has been investigated. Method is from 1966 to 1978 loading test buffer random sampling, the buffer performance test. The findings and deterioration of the criteria are as follows: First, the results of the investigation of the buffer performance 1. Appearance State After three years of use of the buffer, the film has numerous small cracks on the surface, serious discoloration, the formation of white foam state, that produced ozone aging . After more than 13 years of use of the buffer, there is a crack between the rubber of the film and the connecting plate, and a load is obviously opened.
