Four characteristics of dowty retarder for railway vehicles

The characteristics of the dowty retarder of railway vehicles in four aspects are introduced below.

First, adjust the original three standards of the dowty retarder to two. The overall structure of the standards is more reasonable, the level is more clear, the content is more refined and the definition is more accurate.

Second, the standard only stipulates the technical requirements and performance indicators of the product. It does not impose any restrictions on the structure, process and material used. It fully reflects the principle of maximum freedom of the standard and is conducive to the technical innovation and development of dowty retarder.

The third is to improve the primary seal life of dowty retarder. According to the requirements of transportation, the 2 construction speeds of dowty retarder are stipulated, and the advanced technology of the standard is further improved. Meanwhile, the service life index of dowty retarder is stipulated, which provides a basis for overhaul, scrapping and renewal of dowty retarder.

Fourthly, the test method and inspection rules are improved, and the test system of circular rail type simulation test-bed is introduced. Through the adjustment of inspection items, the inspection work of dowty retarder is more convenient and more operable.
