본 발명은 자전거 서스펜션 포크에 관한 것으로, 상세하게는 헤드튜브 내측에 댐퍼조절기가 제공되는 자전거 프런트 서스펜션 포크에 관한 것이다. 상기 자전거 프레임의 헤드튜브에는; 축수부재가 구성되어 상ㆍ하부베어링이 장착되고, 댐퍼조절기는 압축유체의 에어스프링 및 오일유체의 오일댐퍼방식으로 구성된채, 댐퍼조절기의 댐퍼실린더는 시프트로드와 함께 동일회전으로 회동되는 것과; 상기 시프트로드에는 로드결합부재 및 하부축받이가 구성된채, 상기 로드결합부재는; 상기 축수부재의 상측으로 돌출되어 상부축받이를 포함하여 자전거 핸들을 지지하는 스탬 및 고정부재 수단으로 헤드튜브 내측에 회동되게 결합되며, 또한 댐퍼조절기에 구성되는 피스톤에는; 오일유체 흐름을 제어조절하는 댐퍼조절수단이 제공된채, 댐퍼조절수단의 조절봉이 상기 로드결합부재 상측으로 돌출되게 배치되어 댐퍼조작부가 결합되는 것과; 상기 프런트 포크는; 전륜휠이 지지되는 포크튜브수단 및 포크결합수단으로 구성되어 포크튜브수단을 구성하는 포크튜브에는 압축유체가 저장되며, 포크결합수단에는 댐퍼실린더가 결합된채, 포크튜브와 댐퍼실린더 사이에는 압축유체가 출입되는 특징으로 댐퍼조절기의 댐퍼작용이 연출되는 특징을 갖는 자전거 프런트 서스펜션 포크.

    The present invention relates to a front suspension fork for a bicycle and, more specifically, to a front suspension fork for a bicycle, provided with a damper controller in a head tube. An objective of the present invention is to provide a front suspension fork for a bicycle, which is lightweight and has a simple configuration for improving damper performance. A bearing member is provided on the head tube of a bicycle frame to mount an upper and a lower bearing thereon. The damper controller consists of an oil damper of an oil fluid and an air spring of a compressed fluid. A damper cylinder of the damper controller is rotated by the same rotation as a shift rod. The rod coupling member and a lower bearing are provided on the shift rod. The rod coupling member is rotatably coupled into the head tube by a fixing member means and a stem protruding above the bearing member to include an upper bearing to support a bicycle handlebar. A piston provided on the damper controller is provided with a damper control means which controls the flow of the oil fluid. A control bar of the damper control means is arranged to protrude above the rod coupling member to couple a damper operation unit therewith. The front fork consists of a fork coupling means and a fork tube means on which the front wheel is supported. The compressed fluid is stored in a fork tube making up the fork tube means. The damper cylinder is coupled to the fork coupling means. A damper action of the damper controller is presented by introducing and discharging the compressed fluid between the fork tube and the damper cylinder.
