이하 첨부도면에 의하여 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 제2도에 도시된 바와 같이, 코일스프링(12)과 스트러트가 구비된 자동차의 현가장치에 있어서, 스트러트의 피스톤로드(10)를 삽설할 수 있도록 완충부재(20)의 저면 중앙부에 범퍼(22)를 돌설하고 상기 코일스프링(12)의 상부를 지지할 수 있도록 상기 완충부재(20)의 저면 가장자리에 환형요홈(24)을 형성하는 한편, 상기 완충부재(20)의 상부 외주면에 외부브라켓(26)을 덮어씌워 접착시키되, 차체에 장착할 수 있도록 상기 외부브라켓(26)상에 스터드볼트(28)를 수직입설하며, 상기 완충부재(20)의 중앙에 관통공(29)을 형성하고 상기 관통공(29) 내측에 위치된 피스톤로드결합공(30)을 갖는 내부브라켓(32)을 상기 완충부재(20)의 상부에 매설하여 된 특징을 갖는다.As shown in FIG. 2, the present invention provides a suspension device for an automobile provided with a coil spring 12 and a strut, wherein the piston rod 10 of the strut is inserted into a central portion of the bottom surface of the shock absorbing member 20. An annular groove 24 is formed at the bottom edge of the shock absorbing member 20 so as to protrude the bumper 22 and support the upper portion of the coil spring 12, while the upper outer peripheral surface of the shock absorbing member 20 is formed. The outer bracket 26 is covered and glued, but the stud bolts 28 are vertically placed on the outer bracket 26 so as to be mounted on the vehicle body, and the through hole 29 is formed at the center of the buffer member 20. Forming and having an internal bracket 32 having a piston rod coupling hole 30 located inside the through hole 29 is embedded in the upper portion of the buffer member (20).

이와 같은 본 발명에서, 상기 완충부재(20)는 종래의 인슈레이터, 상부스프링패드 및 범퍼고무를 일체화시켜 하나의 부재로 형성한 것으로서, 상기 완충부재(20)의 저면 중앙에 범퍼(22)를 돌설시키는바, 이는 종래의 범퍼고무의 역할을 하며 피스톤로드(10)의 외주연과 밀착 설치되게 된다. 코일스프링(12)이 직접 안착되는 환형요홈(24)은 상기 완충부재(20)의 저면 가장자리에 환형으로 형성한다. 이와 같은 구조의 본 발명에 따른 완충부재(20)를 차체에 고정결합시키기 위하여 외부브라켓(26)의 상부측 외주면상에 스터드볼트(28)를 수직입설하는 바, 그 하부는 외부브라켓(26)상에 융착결합시킨다.In the present invention as described above, the shock absorbing member 20 is formed by integrating the conventional insulator, the upper spring pad and the bumper rubber as a single member, the bumper 22 in the center of the bottom surface of the shock absorbing member 20 As a bar, it serves as a conventional bumper rubber is to be installed in close contact with the outer periphery of the piston rod (10). The annular groove 24 in which the coil spring 12 is directly seated is formed in an annular shape at the bottom edge of the buffer member 20. In order to securely couple the shock absorbing member 20 according to the present invention having such a structure to the vehicle body, the stud bolt 28 is vertically placed on the outer peripheral surface of the upper side of the outer bracket 26, the lower portion of which is the outer bracket 26. Fusion bonding to phase.

또한, 상기 내부브라켓(32)은 완충부재(20)의 중앙에 형성된 관통공(29) 형성부위에 매설시키고 그 중앙부에 피스톤로드결합공(30)을 천공하여 록너트(33)에 의하여 피스톤로드(10)와 결합시킬 수 있도록 한다.In addition, the inner bracket 32 is embedded in the through-hole 29 formed in the center of the buffer member 20 and the piston rod coupling hole 30 in the center of the piston rod by the lock nut 33 To be combined with (10).

본 발명에 따른 상부스프링시트의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the upper spring sheet according to the present invention.

차량 바퀴에 큰 충격이나 진동이 가해지면 일차적으로 스트러트에서 그 충격이 흡수되며, 스트러트에 직설되어 있는 피스톤로드(10)의 상단부는 내부브라켓(32)의 피스톤로드결합공(30)을 통하여 록너트(33)에 의하여 내부브라켓(32)과 결합되어있는 상태이므로 스트러트에서 흡수되지 못한 작은 충격이나 진동은 완충부재(20)의 상부측에서 흡수되게 되고 코일스프링(12)으로부터의 잔진동은 완충부재(20)의 저면 가장자리에 형성된 환형요홈(24) 상부측에서 흡수하게 됨으로써, 진동이나 충격의 흡수 및 조종안전성을 도모할 수 있다.When a large impact or vibration is applied to the vehicle wheels, the impact is first absorbed by the strut, and the upper end of the piston rod 10 directly connected to the strut is locked through the piston rod coupling hole 30 of the inner bracket 32. (33) is coupled to the inner bracket 32, so that a small shock or vibration that is not absorbed by the strut is absorbed from the upper side of the shock absorbing member 20, and the residual vibration from the coil spring 12 is a shock absorbing member ( By absorbing from the upper side of the annular groove 24 formed at the bottom edge of 20), it is possible to absorb the vibration and shock and to control the safety.

한편, 갑작스런 차량의 범핑시 코일스프링(12)에서 흡수하지 못한 충격은 완충부재(20)의 저면 중앙부에 돌설시킨 범퍼(22)에서 흡수하게 된다.On the other hand, the shock not absorbed by the coil spring 12 during sudden bumping of the vehicle is absorbed by the bumper 22 protruding to the center of the bottom surface of the buffer member (20).

이와 같은 본 발명을 적용하면, 소요부품수가 감소되어 조립이 용이하면서도 제작비용이 절감되고, 부품의 관리가 개선되며 조립공수를 감소시킬 수 있다는 효과가 있다.Applying the present invention, the number of parts required is easy to assemble, while reducing the manufacturing cost, there is an effect that the management of parts can be improved and the number of assembly operations can be reduced.
