According to the present invention, a railcar wheel includes: a body including a support body, placed in a rail, and a rotary shaft extended from both sides of the support body; and a flange protruding from the body to form a rail groove, into which the rail is inserted, but formed to be attached to each of both sides of the support body. Therefore, the present invention is capable of reducing costs and workload and increasing productivity with shortened replacement time by replacing only a flange in the wheel as the flange is formed to be attached to each of both sides of the support body. Moreover, the present invention is capable of reducing abrasion, caused by friction with the rail, with an abrasion reducing member formed in the flange, and enhancing combination force for the support body with a separation preventing part.

    본 발명에 따른 궤도차 차륜은, 레일에 안착되는 지지몸체와, 상기 지지몸체의 양측부에 연장된 회전축을 가진 본체; 및 상기 레일이 인입되는 레일홈을 형성토록 상기 본체에 돌출되게 제공되되, 상기 지지몸체의 양측 각각에 탈착되도록 구성되는 플랜지;를 포함한다. 이와 같은 본 발명은, 지지몸체의 양측 각각에 탈착되도록 플랜지가 구성됨으로써, 차륜에서 플랜지만을 교체가능함에 따라 비용 및 작업부하를 절감할 수 있고 나아가 교체시간 단축에 따른 생산성을 높일 수 있다. 또한, 본 발명은 플랜지에 마모저감부재가 구성되어 레일과의 마찰에 따른 마모정도를 저감시킬 수 있고, 탈거방지부가 구성되어 지지몸체에 대한 체결력을 증대시킬 수 있다.
