도1은 종래의 차량 현가장치용 스트러트의 사시도이다(공개실용신안공보 공개번호 2000-16340).1 is a perspective view of a strut for a conventional vehicle suspension device (Publication Utility Model Publication No. 2000-16340).
도1에 도시되어 있듯이, 차량 현가장치용 스트러트(100)는, 오일이 채워진 내부에 밸브(미도시)가 왕복운동하면서 감쇠력을 발생시키는 쇽업소버(110)와, 압축된 쇽업소버(110)를 복원시킬 수 있도록 그 외부에 마련된 코일스프링(140)으로 이루어져 있다.As shown in FIG. 1, the vehicle suspension strut 100 includes a shock absorber 110 and a compressed shock absorber 110 that generate a damping force while a valve (not shown) reciprocates in an oil-filled interior. It is composed of a coil spring 140 provided on the outside to restore.
쇽업소버(110)는, 밸브(미도시)가 수용되는 외통(111)과 상기 밸브(미도시)에 연결되는 로드(120)로 이루어져 있다.The shock absorber 110 includes an outer cylinder 111 in which a valve (not shown) is accommodated and a rod 120 connected to the valve (not shown).
상기 외통(111)에는 너클과 스트러트를 연결하기 위한 너클브래킷(112)이 설치되어 있으며, 상기 너클브래킷(112) 상부에는 로어스프링시트(150)가 외통(111)에 고정되어 있다. 스트러트의 고정위치에 따라 너클브래킷(112) 대신에 원통 형태의 브래킷이 외통(111)의 하부에 설치되는 경우도 있다.The outer cylinder 111 is provided with a knuckle bracket 112 for connecting the knuckle and the strut, and the lower spring sheet 150 is fixed to the outer cylinder 111 on the upper portion of the knuckle bracket 112. Depending on the fixing position of the strut, instead of the knuckle bracket 112, a cylindrical bracket may be installed in the lower portion of the outer cylinder 111.
로어스프링시트(150) 위에 고무재질인 로어스프링패드(152)가 얹혀지며, 로어스프링패드(152) 상부에 코일스프링(140)이 설치된다.The lower spring pad 152 of rubber material is mounted on the lower spring sheet 150, and a coil spring 140 is installed on the lower spring pad 152.
또한, 코일스프링(140)의 상부에는 어퍼스프링패드(162)를 설치한 후 어퍼스프링시트(160)가 쇽업소버(110)의 로드(120)에 삽입된다.In addition, after the upper spring pad 162 is installed on the upper portion of the coil spring 140, the upper spring sheet 160 is inserted into the rod 120 of the shock absorber 110.
어퍼스프링시트(160) 상부에는 인슐레이터(130)가 설치되며, 어퍼스프링시트(160) 및 인슐레이터(130)는 너트(125)를 이용하여 쇽업소버의 로드(120)에 고정시킨다. 차량 전방에 형성되는 스트러트의 경우 조향시 차체에 대하여 스트러트가 회전운동할 수 있도록 인슐레이터(130) 내부에 베어링(미도시)이 설치되는 경우가 있다.An insulator 130 is installed on the upper spring sheet 160, and the upper spring sheet 160 and the insulator 130 are fixed to the rod 120 of the shock absorber using the nut 125. In the case of the strut formed in front of the vehicle, a bearing (not shown) may be installed inside the insulator 130 so that the strut rotates with respect to the vehicle body during steering.
인슐레이터(130)에 형성된 볼트(132)는 스트러트(100)를 차체에 고정시키기 위한 부재이다.The bolt 132 formed on the insulator 130 is a member for fixing the strut 100 to the vehicle body.
도2는 종래 차량 현가장치용 스트러트에 있어서, 로어스프링시트(150)와 쇽업소버 외통(111)이 고정되는 구조를 나타내는 도면이다. 도2에 도시되어 있듯이, 종래 차량 현가장치용 스트러트에 있어서, 로어스프링시트(150)는 외통(111)에 용접으로 고정되고 있다.2 is a view showing a structure in which a lower spring seat 150 and a shock absorber outer cylinder 111 are fixed in a conventional vehicle suspension strut. As shown in Fig. 2, in the conventional vehicle suspension strut, the lower spring seat 150 is fixed to the outer cylinder 111 by welding.

It has been assembled. In this case, since the volume of the lower spring sheet 150 is large, when assembling a component to be inserted into the shock absorber, the work is inconvenient and the size of the assembly jig must be large.
본 발명은, 상기와 같은 종래의 문제점 등을 해결하기 위해 안출된 것으로서, 쇽업소버의 내부 부품들을 완전히 조립한 후 로어스프링시트를 쇽업소버의 외통에 고정할 수 있는 차량 현가장치용 스트러트를 제공하기 위한 것이다.The present invention has been made to solve the above-described problems, such as to provide a strut for a vehicle suspension that can be fixed to the outer cylinder of the shock absorber after completely assembling the internal parts of the shock absorber. It is for.

도3에 도시된 부분을 제외한 본 발명의 차량 현가장치용 스트러트의 나머지 구조는 도1에 도시된 종래의 기술과 동일하기 때문에 어퍼스프링패드(162), 어퍼스프링시트(160) 및 인슐레이트(130) 등에 관한 부분에 대한 설명은 생략한다.The remaining structure of the strut for vehicle suspension of the present invention except for the portion shown in Fig. 3 is the same as the conventional technique shown in Fig. 1, so that the upper spring pad 162, the upper spring seat 160 and the insulator 130 are ) And the description of the parts are omitted.
이하, 본 발명의 작용에 대하여 설명한다.Hereinafter, the operation of the present invention will be described.
먼저, 쇽업소버의 외통(111) 중의 일부에 제1경사부(116), 확관부(118) 및제2경사부(117)로 이루어진 스텝부(115)를 성형한다. 스텝부(115)의 성형에는 일반적인 확관기술을 사용할 수 있다.First, the step part 115 which consists of the 1st inclination part 116, the expansion pipe part 118, and the 2nd inclination part 117 is shape | molded in a part of the outer cylinder 111 of the shock absorber. General forming techniques can be used for forming the step portion 115.
다음에는 쇽업소버의 내부에 삽입되는 밸브류를 조립하여 쇽업소버(110)를 완전히 조립한다.Next, the shock absorber 110 is completely assembled by assembling the valves inserted into the shock absorber.
소경부(157), 경사부(158) 및 압입부(159)로 이루어진 내부플랜지(156)가 성형된 로어스프링시트(150)를 쇽업소버(110)의 외통(111)에 압입하여 고정한다. 즉, 쇽업소버(110)의 확관부(118) 및 로어스프링시트(150)의 압입부(159)가 서로 압입에 의해 고정되기 때문에 로어스프링시트(150)가 외통(111)에 고정되는 것이다.The inner spring 156 formed of the small diameter portion 157, the inclined portion 158, and the press-fit portion 159 is press-fitted into the outer cylinder 111 of the shock absorber 110 to be fixed. That is, since the expansion part 118 of the shock absorber 110 and the press fitting part 159 of the lower spring sheet 150 are fixed to each other by press fitting, the lower spring sheet 150 is fixed to the outer cylinder 111.
쇽업소버(110)의 제1경사부(116) 및 로어스프링시트(150)의 경사부(158)는 압입작업시 스토퍼 작용을 하므로, 제1경사부(116)가 경사부(158)에 완전히 밀착하면 압입작업을 중지한다.Since the first inclined portion 116 of the shock absorber 110 and the inclined portion 158 of the lower spring seat 150 act as a stopper during the press fitting operation, the first inclined portion 116 is completely inclined to the inclined portion 158. If tight, stop the indentation.
또한, 로어스프링시트(150)의 시트면(155) 이면과 내부플랜지(156)의 압입부(159)에 고정된 리브(170)는 압입작업시 로어스프링시트(150)에 작용하는 압입력에 대하여 충분한 강성을 확보하는 작용을 한다.In addition, the rib 170 fixed to the back surface of the seat surface 155 of the lower spring sheet 150 and the press-fit portion 159 of the inner flange 156 is applied to the press input acting on the lower spring sheet 150 during the press-fitting operation. It has a function to secure sufficient rigidity against.
본 발명은 로어스프링시트에 압입부를 형성하고 쇽업소버의 외통에 확관부를 형성하여 로어스프링시트를 압입에 의해 외통에 고정하는 구성을 채택함으로 인하여, 쇽업소버의 내부에 삽입되는 밸브류등을 완전히 조립한 후 로어스프링시트를 외통에 고정할 수 있기 때문에, 쇽업소버의 조립성이 향상된다. 즉, 로어스프링시트를 용접에 의해 외통에 조립하는 경우 쇽업소버의 내부에 삽입되는 부품들로 인하여 쇽업소버를 완전히 조립하기 전에 로어스프링시트를 먼저 용접하여야하고 이 경우 로어스프링시트의 사이즈가 크기 때문에 쇽업소버 내부에 삽입되는 부품을 조립하는 경우 작업성이 저하되는 문제점을 방지하게 된다.The present invention forms a press-fit portion in the lower spring seat and forms an expansion pipe in the outer cylinder of the shock absorber, thereby adopting a configuration in which the lower spring sheet is fixed to the outer cylinder by press-fitting, thereby completely eliminating valves and the like inserted into the shock absorber. Since the lower spring seat can be fixed to the outer cylinder after assembly, the assemblability of the shock absorber is improved. That is, when assembling the lower spring sheet into the outer cylinder by welding, the lower spring sheet must be welded first before the shock absorber is completely assembled due to the parts inserted into the shock absorber. When assembling the parts to be inserted into the shock absorber to prevent the problem of deterioration of workability.
또한, 본 발명은, 쇽업소버 외통의 제1경사부 및 로어스프링시트의 경사부가 압입작업시 스토퍼의 작용을 하기 때문에 압입작업만으로 로어스프링시트의 고정위치를 자동적으로 설정할 수 있게 된다.In addition, the present invention, because the first inclined portion of the shock absorber outer cylinder and the inclined portion of the lower spring sheet acts as a stopper during the press-in operation, it is possible to automatically set the fixed position of the lower spring sheet only by the press-in operation.
또한, 본 발명은 로어스프링시트의 이면에 형성된 리브의 구성으로 인하여, 압입작업시 로어스프링시트의 강성을 충분히 확보할 수 있게 된다.In addition, the present invention, due to the configuration of the rib formed on the back surface of the lower spring sheet, it is possible to ensure the rigidity of the lower spring sheet sufficiently during the press-in operation.
