Abstract

본 발명은 휠 실린더의 피스톤 구조에 관한 것으로, 휠 실린더(20)의 양단에 내장되어 유압의 작용에 따라 출몰하도록 한 피스톤에 있어서, 선단주연에는 경사면(1)을 형성시킨 구조로 이루어져 휠 실린더로부터 피스톤이 외부로 돌출되므로써 브레이크 슈(25)가 회동하여도 브레이크 슈(25)와 피스톤(5)간의 접촉면적이 감소되는것을 방지하여 브레이크 슈(25) 작동이 원활히 이루어지도록 하는 한편, 이에따라 차량의 제동효율을 높이도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piston structure of a wheel cylinder, wherein the piston is built in both ends of the wheel cylinder 20 and floated under the action of hydraulic pressure. As the piston protrudes outward, the contact area between the brake shoe 25 and the piston 5 is prevented from being reduced even when the brake shoe 25 is rotated so that the brake shoe 25 can be operated smoothly. It is to increase the braking efficiency.
