The past 20 years have been a period of rapid development in power electronics technology, and an era in which rapid development of mine electric locomotives technology has also been achieved.

The return time is also an important technical indicator of the dowty retarder, which directly affects the effect of the deceleration top on the vehicle's work.

If the installation height of the dowty retarder is changed, the height of the contact point between the wheel and the dowty retarder cylinder will also change.

What are the requirements for the use of retarder of railway vehicles? Here is an introduction.

Through the analysis of several schemes, it can be seen that the above several dowty retarder can achieve the purpose of improving the structural speed of dowty retarder, each with its own advantages.

The dowty retarder is a kind of equipment which uses hydraulic oil and elastomer as the medium, is installed on the rail, contacts with the wheel through the cap of the sliding cylinder, and plays the
