본 발명은 자동변속기의 파킹 장치용 윤활 장치에 관한 것으로서, 더욱 상세하게는 자동변속기의 변속단을 파킹(P)단에 놓았을 때, 변속기어중 파킹기어를 구속하는 자동변속기의 파킹 장치에 관한 것으로서, 이 파킹 장치의 섭동부에 대한 윤활을 제공하여 파킹 해제시 변속 작동이 원활하게 이루어질 수 있도록 한 자동변속기의 파킹 장치용 윤활 장치에 관한 것이다.The present invention relates to a lubrication device for a parking device of an automatic transmission, and more particularly, to a parking device for an automatic transmission that constrains a parking gear of a transmission gear when the transmission end of the automatic transmission is placed at the parking (P) end. The present invention relates to a lubrication device for a parking device of an automatic transmission that provides lubrication for the perturbation portion of the parking device so that the shifting operation can be smoothly performed when the parking is released.

주지된 바와 같이, 자동변속기는 운전자가 P-R-N-D-S-L 레인지 중에서 하나를 선택하여 변속레버를 조작하는 것에 의해 그 조작력이 유압제어 시스템에 의해 제어되어 전진 1속에서 4속까지와 후진 1속변속이 이루어지게 된다.As is well known, the automatic transmission allows the driver to select one of the PRNDSL ranges and operate the shift lever so that the operating force is controlled by the hydraulic control system so that forward 1 to 4 speed and reverse 1 speed are achieved. .

여기서 D, S 및 L레인지 상태일 때는 토크 변환기의 특성 때문에 가속페달을 밟지 않아도 차량이 전진하게 되며, 토크 변환기의 특성이란, 터어빈 러너의 회전속도가 펌프 임펠러의 회전속도보다 빠르기 때문에 그 차이만큼의 오일이 순환되어 동력전달이 이루어지는 특성을 말한다.In the D, S, and L ranges, the vehicle moves forward without the accelerator pedal due to the characteristics of the torque converter.The characteristics of the torque converter are that the speed of the turbine runner is faster than that of the pump impeller. It is the characteristic that the power is transmitted by the oil circulating.

따라서, 상기와 같은 현상 때문에 오직 P 또는 N 레인지에서만 시동이 걸리도록 되어 있으며, 특히, P 레인지는 주차시에 사용되는 레인지이다.Therefore, because of the above phenomenon, only the P or N range is started, and in particular, the P range is a range used for parking.

자동변속기의 파킹 시스템은 첨부한 도 5 및 도 6에 도시된 바와 같이 자동변속기의 기어들중 파킹기어를 구속 또는 해제시키도록 파킹기어(10)의 기어홈에 끼워지거나 빠지는 돌출부(12)를 갖는 스프래그(14)와; 이 스프래그(14)의 이동시 원위치로 탄성 복원시키는 스프링(16)과; 상기 스프래그(14)의 돌출부(12) 반대쪽의 전단부 아래에 위치하는 서포트(18)와; 상기 스프래그(14)의 전단부와 상기 서포트(18) 사이공간에 위치하는 경사진 형태의 캠(20)과; 상기 캠(20)을 직선 이동시키는 파킹로드(22)를 포함하여 구성되어 있다.The parking system of the automatic transmission has protrusions 12 that fit into or out of the gear grooves of the parking gear 10 to restrain or release the parking gears of the gears of the automatic transmission, as shown in FIGS. 5 and 6. A sprag 14; A spring 16 which elastically restores to its original position when the sprag 14 is moved; A support (18) positioned below the front end of the sprag (14) opposite the protrusion (12); An inclined cam 20 located in a space between the front end of the sprag 14 and the support 18; The parking rod 22 which linearly moves the cam 20 is comprised.

따라서, 사용자가 변속단을 P단으로 놓으면, 파킹로드(22)가 당겨지면서 캠(20)의 대직경부가 상기 스프래그(14)의 전단부와 상기 서포트(18) 사이공간에 위치하게 되고, 이에 캠(20)의 대직경부가 스프래그(14)의 전단부를 들어올리게 되며, 이와 동시에 스프래그(14)의 후단부 즉, 돌출부(12)가 상기 파킹기어(10)의 기어홈으로 삽입되어 구속하는 상태가 되어, 결국 파킹이 이루어지게 된다.Therefore, when the user puts the gear shift stage to the P stage, the parking rod 22 is pulled and the large diameter portion of the cam 20 is located in the space between the front end portion of the sprag 14 and the support 18, Accordingly, the large diameter portion of the cam 20 lifts the front end of the sprag 14, and at the same time, the rear end of the sprag 14, that is, the protrusion 12 is inserted into the gear groove of the parking gear 10. The restraint condition results in parking.

그러나, 이러한 자동변속기의 파킹 시스템은 다음과 같은 단점이 있다.However, the parking system of such an automatic transmission has the following disadvantages.

차량을 주차하고 있는 동안 파킹시스템을 작동시키는 캠은 항상 어느정도의 하중을 가지고 있으며, 이런 하중을 받고 있는 캠은 오일윤활을 항상 해주면 조작력을 좋게할 수도 있지만, 차량을 일정시간 세워두면 변속기 내부에서 자연윤활에의한 오일공급이 이루어지지 않는 경우도 있으므로, 상기 캠에 오일이 없어져서 "P"에서 파킹을 해제시 금속면의 마찰증가로 "P" 해제가 어려운 경우가 발생할 수 있다.The cams that operate the parking system while parking the vehicle always have a certain amount of load, and the cams under these loads can be operated with oil lubrication at all times, but the operating force can be improved. Since the oil supply may not be performed by lubrication, it may be difficult to release the “P” due to the friction of the metal surface when releasing the parking at the “P” due to the oil disappearing from the cam.

즉, 파킹 해제시 상기 캠의 대직경부가 상기 스프래그의 전단부와 상기 서포트 사이공간에서 이탈될 때 발생하는 금속 마찰 현상과 함께 상기 캠에 오일이 없어진 경우에는 금속면의 마찰증가로 "P" 해제가 어려운 경우가 발생할 수 있다.In other words, when the large diameter portion of the cam is released from the space between the front end portion of the sprag and the support when the parking is released, when the oil is removed from the cam, the friction of the metal surface is increased by "P". Difficult release may occur.

본 발명은 상기와 같은 단점을 해결하기 위하여 안출한 것으로서, 파킹장치의 캠과 스프래그와 서포트쪽에 분사노즐을 이용하여 "P" 작동시 오일을 뿌려주어서 강체 접촉면의 윤활성을 개선시켜 줌으로써, 그리고 오일 분사시 오일이 캠에 잘 머물러 있도록 캠에 오일저장홈을 형성하여 줌으로써, "P"에서 파킹을 해제시 금속면의 마찰 감소로 "P" 해제가 용이하게 이루어질 수 있도록 한 자동변속기의 파킹 장치용 윤활 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above disadvantages, by spraying the oil during the "P" operation using the spray nozzle on the cam, the sprag and the support of the parking device to improve the lubricity of the rigid contact surface, and the oil For the parking device of the automatic transmission, by forming the oil storage groove in the cam so that the oil stays on the cam well when spraying, the "P" can be easily released by reducing the friction of the metal surface when releasing the parking at "P". The object is to provide a lubrication device.

상기한 목적을 달성하기 위한 본 발명은 자동변속기용 파킹기어의 기어홈에 끼워져 구속하는 스프래그와, 상기 스프래그의 아래쪽에 위치하는 서포트와, 상기 스프래그와 상기 서포트 사이공간에 위치하는 캠과, 상기 캠을 직선 이동시키는 파킹로드를 포함하는 자동변속기의 파킹 장치에 있어서,In order to achieve the above object, the present invention provides a sprag that is inserted into and restrained by a gear groove of an automatic transmission parking gear, a support positioned below the sprag, a cam positioned in the space between the sprag and the support; In the parking device of the automatic transmission comprising a parking rod for linearly moving the cam,

상기 스프래그와 서포트와 캠이 조합된 부분을 향하여 "P" 단시 오일을 분사시키는 분사노즐과; 상기 분사노즐에 대한 오일 공급수단과; "P" 단을 감지하여 상기 오일 공급수단을 열림 작동시키는 제어부를 포함하여 구성된 것을 특징으로 하는 자동변속기의 파킹 장치용 윤활 장치를 제공한다.A spray nozzle for spraying oil "P" upon the portion where the sprag, the support, and the cam are combined; Oil supply means for the injection nozzle; It provides a lubrication device for a parking device of an automatic transmission, characterized in that it comprises a control unit for detecting the "P" stage to open the oil supply means.

바람직한 구현예로서, 상기 오일 공급수단은: 오일을 공급하는 밸브바디와; 밸브바디와 상기 분사노즐간에 형성된 유로와; 상기 유로의 중간부분에 장착되어 상기 제어부의 신호에 따라 개폐되는 솔레노이드 밸브로 구성된 것을 특징으로 한 다.In a preferred embodiment, the oil supply means comprises: a valve body for supplying oil; A flow path formed between a valve body and the injection nozzle; It is characterized in that the solenoid valve is mounted to the middle portion of the flow path is opened and closed in accordance with the signal of the controller.

전술한 바와 같이, 자동변속기의 파킹 시스템은 자동변속기의 기어들중 파킹기어를 구속 또는 해제시키도록 파킹기어(10)의 기어홈에 끼워지거나 빠지는 돌출부(12)를 갖는 스프래그(14)와; 이 스프래그(14)의 이동시 원위치로 탄성 복원시키는 스프링(16)과; 상기 스프래그(14)의 돌출부(12) 반대쪽의 전단부 아래에 위치하는 서포트(18)와; 상기 스프래그(14)의 전단부와 상기 서포트(18) 사이공간에 위치하는 경사진 형태의 캠(20)과; 상기 캠(20)을 직선 이동시키는 파킹로드(22)를 포함하여 구성되어 있다.As described above, the parking system of the automatic transmission includes: a sprag 14 having a projection 12 fitted into or out of the gear groove of the parking gear 10 to restrain or release the parking gear among the gears of the automatic transmission; A spring 16 which elastically restores to its original position when the sprag 14 is moved; A support (18) positioned below the front end of the sprag (14) opposite the protrusion (12); An inclined cam 20 located in a space between the front end of the sprag 14 and the support 18; The parking rod 22 which linearly moves the cam 20 is comprised.

이러한 구성의 파킹장치에 본 발명은 상기 스프래그(14)와 서포트(18)와 캠(20)이 조합된 부분을 향하여 윤활을 위한 오일 분사수단을 더 설치하여, "P"에서 파킹을 해제시 금속면의 마찰 감소로 "P" 해제가 용이하게 이루어질 수 있도록 한 점에 주안점이 있다.In the parking device of this configuration, the present invention further installs oil injection means for lubrication toward the combined portion of the sprag 14, the support 18, and the cam 20, and releases the parking at "P". The focus is on reducing the friction of the metal surface to facilitate the "P" release.

본 발명의 윤활장치는 상기 스프래그(14)와 서포트(18)와 캠(20)이 조합된 부분의 아래쪽에 "P" 단시 오일을 분사시키는 분사노즐(22)을 설치하고, 이 분사노즐(22)에 오일공급수단을 연결하며, "P" 단 감지시 상기 오일 공급수단을 열림 작동시킬 수 있도록 오일공급수단에 신호교환 가능하게 제어부(24)가 연결되어 이루어진다.The lubrication apparatus of the present invention is provided with a spray nozzle 22 for spraying "P" short oil at the bottom of the combination of the said sprag 14, the support 18, and the cam 20, and this spray nozzle ( 22) is connected to the oil supply means, the control unit 24 is connected to the oil supply means so that the oil supply means can be opened to operate when the "P" stage is detected.

보다 상세하게는, 상기 오일 공급수단은 변속기 오일이 충진된 밸브바디(26)와, 이 밸브바디(26)와 상기 분사노즐(22)간에 형성된 유로(28)와, 상기 유로(28)에 장착되어 상기 제어부(24)의 신호에 따라 개폐되는 솔레노이드 밸브(30)로 구성된다.More specifically, the oil supply means includes a valve body 26 filled with transmission oil, a flow path 28 formed between the valve body 26 and the injection nozzle 22, and mounted in the flow path 28. It is composed of a solenoid valve 30 which is opened and closed in accordance with the signal of the control unit 24.

이때, 상기 분사노즐(22)은 유로(28)의 끝단에 압입 체결된다.At this time, the injection nozzle 22 is press-fitted to the end of the flow path (28).

따라서, 차량의 주정차시 "P"으로 놓게 되면, 전술한 바와 같이 파킹로드(10)가 당겨지면서 캠(20)의 대직경부가 상기 스프래그(14)의 전단부와 상기 서포트(18) 사이공간에 위치하게 되고, 이에 캠(20)의 대직경부가 스프래그(14)의 전단부를 들어올리게 되며, 이와 동시에 스프래그(14)의 후단부 즉, 돌출부가 상기 파킹기어(10)의 기어홈으로 삽입되어 구속하는 상태가 되어, 결국 파킹이 이루어지게 된다.Therefore, when the vehicle is placed at "P" during parking, the parking rod 10 is pulled as described above, and the large diameter portion of the cam 20 is spaced between the front end of the sprag 14 and the support 18. The large diameter portion of the cam 20 lifts the front end portion of the sprag 14, and at the same time, the rear end portion of the sprag 14, that is, the protrusion portion, moves to the gear groove of the parking gear 10.
