본 고안은 냉각기능이 구비된 자동차 파워스티어링 장치의 오일 리저버에 관한 것으로서, 더욱 상세하게는 자동차 파워스티어링 장치(Power Streering System)의 오일 리저버(Oil Reservoir)에 냉각기능을 부여하여 파워스티어링 장치에서 순환되는 작동오일을 냉각시킴으로써, 파워스티어링 장치의 원활한 작동을 도모할 수 있는 오일 리저버에 관한 것이다.The present invention relates to an oil reservoir of an automotive power steering device equipped with a cooling function, and more particularly, to provide a cooling function to an oil reservoir of an automotive power steering system, thereby circulating in a power steering device. The present invention relates to an oil reservoir capable of smoothly operating a power steering apparatus by cooling a working oil.

일반적으로 오일 리저버(10)는, 자동차의 파워스티어링 장치에 적용되는 경우를 일례로 들어 설명하면, 첨부된 도면 제1도에 도시된 바와 같이, 파워스티어링 펌프(1)에서 송출된 작동오일이 고압파이프(2)를 경유하여 파워스티어링 기어(3)의 파워피스톤(도시되지 않았음)을 작동시킨 후 귀환되는 통로인 리턴파이프(4)(return flow pipe)와 상기 파워스티어링펌프(1)로 흡입되는 작동오일 통로인 석션호스(suceion hose)(5) 사이에 위치해서 작동오일을 저장하거나 또는 충진할 수 있도록 설치된 일종의 오일 저장탱크로서, 그 내부에는 필터가 안착되어 있어, 귀환되는 작동오일에 포함된 각종 이물질을 여과하여 주는 것이다.In general, when the oil reservoir 10 is applied to a power steering apparatus of an automobile by way of example, as shown in FIG. 1 of the accompanying drawings, the operating oil sent from the power steering pump 1 is high pressure. After operating the power piston (not shown) of the power steering gear 3 via the pipe 2, the suction pipe is returned to the return flow pipe 4 and the power steering pump 1. It is a kind of oil storage tank which is located between suction hoses 5, which are passages of operating oils, to store or fill the operating oils, and has a filter mounted therein so that it is included in the returned operating oils. It is to filter the various foreign matters.

이러한 종래의 오일 리저버(10)의 형상 및 구성을 구성을 첨부된 도면 제2도에 도시하였다.The shape and configuration of such a conventional oil reservoir 10 are shown in FIG. 2 of the accompanying drawings.

도시된 바와 같이 오일 리저버(10)는 귀환되는 작동오일의 입구인 리턴포트(11)와 파워스티어링펌프(1)로 흡입되는 석션포트(12)가 구비된 원통형의 로워 바디(13)와, 상기 로워 바디(13)의 저면에 안착된 원통형의 필터(14)와, 상기 로워 바디(13)와 원주접합된 어퍼바디(15)와, 상기 어퍼바디(15)의 상단에 탈착 가능하도록 조립된 캡(16)으로 구성되어 있다.As illustrated, the oil reservoir 10 includes a cylindrical lower body 13 having a return port 11, which is an inlet of the returning operating oil, and a suction port 12 sucked into the power steering pump 1. A cylindrical filter 14 seated on the bottom of the lower body 13, an upper body circumferentially bonded to the lower body 13, and a cap assembled to be detachably attached to an upper end of the upper body 15. It consists of (16).

파워스티어링 기어(3)를 작동시키고 귀환되는 작동오일은 리턴포트(11)를 통하여 필터(14)를 내측으로 유입되어 필터(14) 외측으로 빠져나가면서 여과된 후 상기 필터(14) 외측 하부의 로워 바디(13)에 형성된 석션포트(12)로 송출되어 파워스티어링펌프(1)로 흡입되어진다, 이렇게 파워스티어링펌프(1)로 흡입된 작동오일은 그 압력이 상승한 후 파워스티어링기어(3)로 송출된다.After operating the power steering gear 3 and returning the operating oil, the filter 14 is introduced into the filter 14 through the return port 11 to the outside of the filter 14 and then filtered. The suction oil is sent to the suction port 12 formed in the lower body 13 and sucked into the power steering pump 1. The operating oil sucked into the power steering pump 1 is increased by the pressure and then the power steering gear 3. Is sent out.

파워스티어링기어(3)로 송출된 작동오일이 파워스티어링기어(3)의 파워피스톤을 작동시킬때는 파워스티어링기어(3)를 회전시켜 휘일(도시되어 있지않음)의 방향을 전환할 수 있을 만큼의 많은 일을 하게 된다.When the operating oil delivered to the power steering gear 3 operates the power piston of the power steering gear 3, the power steering gear 3 is rotated so that the direction of the wheel (not shown) can be changed. You do a lot of work.

이때 상기 작동오일에 작용하는 압력에너지의 일부가 열에너지로 변환되어 파워스티어링기어(3)를 작동시킨후의 작동오일은 상당히 높은 온도를 갖게 된다.At this time, a part of the pressure energy acting on the operating oil is converted into thermal energy, so that the operating oil after operating the power steering gear 3 has a considerably high temperature.

따라서 종래에는 파워스티어링기어(3)를 작동시키고 오일 리저버(10)로 귀환되는 작동오일을 냉각시키기 위하여 리턴파이프(4)의 일부가 라디에이터(6)의 후방을 길게 선회하도록 하는 쿨링루프(C/L)(제1도 참조)를 형성하여 오일 리저버(10)로 귀환되는 작동오일을 다소 냉각시켰다.Therefore, in order to operate the power steering gear 3 and cool the operating oil returned to the oil reservoir 10, a cooling loop C / to allow a part of the return pipe 4 to be turned long behind the radiator 6 in the related art. L) (see FIG. 1) was formed to cool the operating oil back to the oil reservoir 10 somewhat.

그러나 작동오일이 상기 쿨링루프(C/L)를 통하여 냉각된다 하더라도 그 냉각효과가 기대에 미치지 못하였다. 따라서 고온의 작동오일의 일부가 미량 증발하여 생긴 기체가 작동오일이 순환하는 관내에 체류함으로써 작동오일의 정상적인 순환을 제해하는 문제가 여전히 남게 되었다.However, even though the operating oil was cooled through the cooling loop C / L, the cooling effect did not meet expectations. Therefore, the problem of restraining the normal circulation of the working oil remains by allowing the gas generated by a small amount of the high temperature working oil to evaporate in the tube through which the working oil circulates.

본 고안은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위하여 오일 리저버의 로워 바디와 어퍼바디의 측벽을 접촉면적이 넓은 구조로 형성하여 이 접촉면을 통하여 외부공기와 접촉함으로써 보다 신속하고 충분한 냉각효과를 보장하는데 그 목적이 있다.The present invention has a wide contact area of the lower body and the upper body of the oil reservoir in order to solve the problems of the prior art as described above to contact the outside air through this contact surface to provide a more rapid and sufficient cooling effect The purpose is to ensure.

본 고안은 상기와 같은 목적을 달성하기 위하여 로워 바디와 어퍼바디가 구비된 오일 리저버에 있어서, 상기 로워 바디와 어퍼바디의 측벽이 원주를 따라 입출된 다수의 접촉부로 형성된 것을 특징으로 한다.The present invention is characterized in that in the oil reservoir provided with a lower body and the upper body in order to achieve the above object, the lower body and the upper side wall is characterized in that formed by a plurality of contact portions entered along the circumference.

이하, 첨부된 도면을 참조하여 본 고안의 실시예를 구체적으로 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

이하, 종래에 있어서와 동일한 부품에 대해서는 동일한 부호를 부여하여 설명한다.Hereinafter, the same components as in the prior art will be described with the same reference numerals.

제3도는 본 고안에 따른 오일 리저버(20)의 로워 바디(21)와, 어퍼바디(22) 및 이에 결합된 각 부품들을 도시한 것이다.3 shows the lower body 21, the upper body 22, and the respective components coupled thereto of the oil reservoir 20 according to the present invention.

도시된 바와 같이 본 고안의 로워 바디(21)와 어퍼바디(22)는 그 측벽(23, 24)이 각각 원주를 따라 굴곡되어 입출된 다수의 접촉부(25, 26)로 이루어진 것으로서, 외부의 찬 공기와 접촉되는 접촉면적을 극대화하여 냉각효율을 높일 수 있는 구조로 형성한 것이다.As shown, the lower body 21 and the upper body 22 of the present invention are composed of a plurality of contact portions 25 and 26 whose side walls 23 and 24 are bent along the circumference, respectively, It is formed into a structure that can maximize cooling area by maximizing contact area in contact with air.

이와 같이 구성된 본 고안의 작용 및 효과를 설명한다.The operation and effects of the present invention configured as described above will be described.

본 고안에 있어서, 파워스티어링기어(3)를 작동시킨 고온의 작동오일은 라디에이터(6)의 후방에 형성된 리턴파이프(4) 즉, 쿨링루프(C/L)를 경유함으로써 일차로 냉각된다.In the present invention, the high temperature working oil in which the power steering gear 3 is operated is primarily cooled by way of the return pipe 4 formed at the rear of the radiator 6, that is, the cooling loop C / L.

이와 같이 일차로 냉각된 작동오일은 리턴포트(11)를 통하여 오일 리저버(20)내부로 유입되어 로워 바디(21) 저면에 안착된 필터(14)를 통과하며 여과된다.The operation oil cooled in this way is introduced into the oil reservoir 20 through the return port 11 and filtered through the filter 14 seated on the bottom of the lower body 21.

이때, 신규로 유입된 작동오일은 오일 리저버(2) 내부에 이미 체류하고 있는 작동오일과 혼합되게 된다. 이 과정에서 체류하고 있는 오일과 신규로 유입된 작동오일은 로워 바디(21)과 어퍼바디(22)의 측벽(34, 24)에 굴곡되어 형성된 다수의 접촉부(25, 26)에 첩촉하거나 또는 부딪친다. 상기 접촉부(25, 26)는 원주를 따라 입출된 형상으로서 외부 공기와의 접촉면적이 상당히 크므로 쿨링루프(C/L)를 통하여 일차적으로 냉각된 작동오일이 신속하게 재차 냉각되는 것이다.At this time, the newly introduced working oil is mixed with the operating oil already remaining in the oil reservoir 2. The oil staying in this process and the newly introduced working oil are in contact with or bumped into a plurality of contact portions 25 and 26 formed by bending on the side walls 34 and 24 of the lower body 21 and the upper body 22. All. Since the contact portions 25 and 26 have a shape of entering and exiting along the circumference, the contact area with the external air is considerably large, so that the operating oil primarily cooled through the cooling loop C / L is rapidly cooled again.

이와 같이 냉각된 작동오일은 파워스티어링펌프(1)를 통하여 파워스티어링기어(3)에 공급되어져서 소정의 역할을 수행하는 것이다.The operation oil cooled in this way is supplied to the power steering gear 3 through the power steering pump 1 to perform a predetermined role.

상술한 바와 같이 본 고안에 따라 로워 바디와 어퍼바디의 측벽이 원주를 따라 굴곡되어 입출된 다수의 접촉부로 이루어짐으로써 고온의 작동오일을 보다 신속하고 충분히 냉각시켜 최적의 파워스티어링 작동상태를 유지할 수 있는 효과가 있다.As described above, the side wall of the lower body and the upper body is formed of a plurality of contact portions that are bent and circumferentially circumferentially and thus cool the hot operation oil more quickly and sufficiently to maintain an optimum power steering operation state. It works.
