The present invention relates to a friction reduction system between wheels and rails of a hydrogen fuel cell railway vehicle. More particularly, the friction reduction system comprises: a tank unit installed in a hydrogen fuel cell railway vehicle to store water generated by the hydrogen fuel cell; a nozzle unit which is installed in the hydrogen fuel cell railway vehicle and sprays water on the wheel; a pump unit installed between the tank unit and the nozzle unit to supply water in the tank unit to the nozzle unit; and a control unit for controlling the pump unit. As friction between wheels and rails can be reduced by using water generated from a hydrogen fuel cell, maintenance time and cost can be reduced compared to oil lubrication systems using oil and, in addition, environmental pollution can also be prevented.
본 발명은 수소연료전지 철도차량의 차륜과 레일간 마찰저감 시스템에 관한 것으로, 특히 수소연료전지 철도차량에 설치되어 수소연료전지에서 생성되는 물을 저장하는 탱크부와, 수소연료전지 철도차량에 설치되어 물을 차륜에 분사하는 노즐부와, 상기 탱크부 및 노즐부 사이에 설치되어 탱크부 내의 물을 노즐부로 공급하는 펌프부와, 상기 펌프부를 제어하기 위한 제어부를 포함하여 이루어짐으로서, 수소연료전지에서 생성되는 물을 이용하여 차륜과 레일간에 마찰을 저감할 수 있음에 따라, 오일을 이용하는 도유시스템 보다 유지보수 시간 및 비용을 절감할 수 있고, 또 환경오염도 방지할 수 있는 특출한 발명이다.
