美国韦斯汀豪斯空气制动机公司(WABCO)新近开发了一种EL—X型新的空重车制动机,现已进入最后研制阶段。这种制动装置预计于1991年年初投入运用,并将最终取代WABCO的SC—1型和已单元化了的SC—1U型制动装置。 EL—X型制动机兼备载荷传感和压力比例可变等功能,是一种结构紧凑的单元装置,其大小只有单个S—1型载荷传感器那么大。均衡风缸容积的要求亦大大减小尺寸,从而研制出了总体布置非常紧凑的制动装置。
The Westinghouse Air Brake Company (WABCO) has recently developed a new EL-X empty truck brake, which is now in the final stages of development. The brake is expected to come on stream in early 1991 and will eventually replace WABCO’s SC-1 and the already unitized SC-1U brake. Featuring both load sensing and variable pressure ratio capabilities, the EL-X is a compact unit that measures as large as a single S-1 load cell. The requirement of equalizing the volume of the cylinder is also greatly reduced in size, resulting in a very compact overall brake arrangement.
