Abstract

PURPOSE: A ball bearing type bush assembly structure for a shock absorber is provided to improve proof lateral load capacity of a piston rod by installing the ball bearing type bush to an inner surface of a rod guide instead of a guide bush. CONSTITUTION: A ball bearing type bush forms a concave portion(10) along an inner surface of a rod guide slid with a piston rod. A ball bearing assembly(11) is installed to the concave portion by arranging ball bearings(13) to frictionize rollingly an outer surface of the piston rod lifted up and down by a damping operation of a shock absorber. The ball bearing assembly comprises ball bearings and a support member. The support member stores ball bearings as a ring shape. Ball bearings are protruded by forming an opening around an inner peripheral surface of the support member. Consequently, proof lateral load capacity is improved, and wearing of ball bearings by the piston rod is reduced.

Description

쇽 업소버의 볼 베어링 타입 부시 조립구조{ASSEMBLY STRUCTURE OF BALL BEARING TYPE BUSH IN A SHOCK ABSORBER}볼 Assembly structure of ball bearing type bush in a shock ABSORBER

본 발명은 쇽 업소버에 관한 것으로서, 더욱 상세하게는 피스톤 로드와 습동되는 로드 가이드 내측면에 볼 베어링 타입의 부시를 설치하여 스트러트에 부가되는 횡하중성을 증대시킨 쇽 업소버의 볼 베어링 타입 부시에 관한 것이다.The present invention relates to a shock absorber, and more particularly, to a ball bearing type bush of a shock absorber having a ball bearing type bush installed on an inner surface of a rod guide that slides with a piston rod to increase lateral load added to a strut. .

현가장치는 액슬축과 차체를 연결하고, 주행중의 노면에서 받은 진동이나 충격을 흡수하여 승차 감이나 자동차의 안전성을 향상시켜 주는 중요한 장치이다. 이 장치에는 노면으로부터의 진동이나 충격에 의한 급격한 상하운동을 흡수하는 스프링과 스프링의 자유진동을 조정하여 승차감을 좋게 해주는 쇽 업소버, 자동차의 좌우진동을 방지하는 스태빌라이저 등으로 구성되어 있다.Suspension is an important device that connects the axle shaft to the vehicle body and absorbs vibrations and shocks received from the road surface while driving to improve the riding comfort and safety of the vehicle. The device consists of a spring that absorbs rapid up and down movement due to vibrations and shocks from the road surface, a shock absorber that adjusts the free vibration of the spring to improve ride quality, and a stabilizer that prevents the left and right vibrations of the car.

쇽 업소버는 노면에 의해 발생된 스프링의 진동을 재빨리 흡수하여 승차감을 향상시키고, 동시에 스프링의 피로를 줄이기 위해 설치하는 장치이다. 즉, 쇽 업소버의 역할은 스프링의 상하운동 에너지를 열에너지로 변환시키고, 주행중의 충격에 의해 발생된 스프링의 고유 진동을 흡수해 준다.Shock absorber is a device installed to quickly absorb the vibration of the spring generated by the road surface to improve the riding comfort and at the same time reduce the fatigue of the spring. That is, the shock absorber's role is to convert the up and down kinetic energy of the spring into thermal energy, and absorbs the natural vibration of the spring generated by the shock while driving.

이와 같은 쇽 업소버의 일예가 도 1에 도시되어 있다.One example of such a shock absorber is shown in FIG.

도 1에 도시된 바와 같이, 쇽 업소버는 안내를 겸한 길고 가는 원통형 튜브(5)와 베이스 쉘(1)의 조합으로 구성되어 있고, 튜브(5) 내부에 왕복운동가능하게 설치되는 피스톤 밸브(3)를 왕복운동시키며 차체에 설치되는 피스톤 로드(2)가 설치되며, 베이스 쉘(1) 및 튜브(5) 내부에는 오일이 적정량 채워져 있다.As shown in FIG. 1, the shock absorber is composed of a combination of a long and thin cylindrical tube 5 serving as a guide and a base shell 1, and a piston valve 3 reciprocally installed inside the tube 5. Piston rod (2) is installed on the vehicle body to reciprocate) is installed, the base shell (1) and the tube (5) inside the appropriate amount of oil is filled.

한편, 베이스 쉘(1)과 튜브(5) 상단부에는 피스톤 로드(2)의 상, 하 이동을 안내하는 동시에 피스톤 로드(2)를 횡방향으로 지지하는 로드 가이드(6)가 설치되며, 로드 가이드(6) 상부에는 베이스 쉘(1)을 밀봉결합하기 위한 오일실(7) 및 캡(8)이 설치된다.On the other hand, at the upper end of the base shell 1 and the tube 5, a rod guide 6 for guiding the piston rod 2 up and down and supporting the piston rod 2 laterally is installed. (6) An oil chamber 7 and a cap 8 for sealingly coupling the base shell 1 are provided at the top.

또한, 로드 가이드(6)의 내주면 즉, 피스톤 로드(2)와 습동되는 면에는 소결품인 로드 가이드(6)의 내경면이 거친 표면상태를 유지하고 있으므로 표면이 매끄러운 안내부시(9)를 압입하여 습동면의 마찰을 줄임으로써 피스톤 로드(2)의 상, 하측 이동을 보다 원활히 안내한다.In addition, the inner circumferential surface of the rod guide 6, that is, the surface sliding with the piston rod 2, maintains a rough surface state of the inner diameter of the rod guide 6, which is a sintered product, and thus press-fits the guide bush 9 having a smooth surface. By reducing the friction of the sliding surface to guide the up and down movement of the piston rod (2) more smoothly.

그러나, 이와 같은 종래의 쇽 업소버의 안내 부시는 피스톤 로드(2)의 횡하중성을 견디는 내횡하중성이 약한 단점이 있었다. 이처럼, 안내 부시(9)가 피스톤 로드(2)의 횡하중에 충분히 견뎌주지 못하면 쇽 업소버의 수명단축 및 소음발생의 원인을 제공한다.However, the guide bush of the conventional shock absorber has a weak side load resistance that withstands the lateral load of the piston rod (2). Thus, failure of the guide bush 9 to withstand the lateral load of the piston rod 2 sufficiently shortens the life of the shock absorber and causes noise.

본 발명은 상술한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 로드 가이드 내측면에 안내 부시를 대신하여 볼 베어링 타입의 부시를 설치함으로써 피스톤 로드의 내횡하중성을 증대시킬 수 있는 쇽 업소버의 볼 베어링 타입 부시를 제공하는데 그 목적이 있다.The present invention is to solve the conventional problems as described above, the ball bearing of the shock absorber that can increase the lateral load resistance of the piston rod by installing a ball bearing type bush on the inner surface of the rod guide instead of the guide bush The purpose is to provide a type bush.

이와 같은 목적을 달성하기 위한 본 발명은 피스톤 로드와 습동되는 로드 가이드의 내측면에 운동 직각방향으로 내주면을 따라 오목부가 형성되고, 상기 오목부에 볼 베어링이 링형상으로 배열 설치된 볼 베어링 조립체가 설치되는 것을 특징으로 하는 쇽 업소버의 볼 베어링 타입 부시를 제공한다.In order to achieve the above object, the present invention provides a concave portion formed along an inner circumferential surface at a right angle to the inner surface of the rod guide that slides with the piston rod, and a ball bearing assembly in which the ball bearings are arranged in a ring shape. A ball bearing type bush of shock absorber is provided.
