高速列车的发展不断推动新型制动装置的研究工作。许多国家都在走它自己的研究道路,而且往往受其具体环境所支配。然而,尽管在发展辐板制动或动力制动,但在可以预见的将来踏面闸瓦制动仍然是主要的制动装置之一。含磷3%左右的高磷闸瓦正在取代一般含磷1%的闸瓦,并已用于英国某些电动车组和 The development of high-speed trains continue to promote the research work of new brake devices. Many countries are following their own path of research and are often dominated by their specific circumstances. However, despite the development of spoke braking or dynamic braking, braking of the brake shoe remains one of the major braking devices for the foreseeable future. Phosphorus brake shoes with a phosphorus content of about 3% are replacing brake shoes with 1% phosphorus in general and have been used in some British EMUs and
