Description
본 발명은 변속기용 유압제어장치에 관한 것으로서, 보다 상세하게는 유압회로 및 작동구조를 단순화시켜 구동 응답성을 개선하고, 구동 손실을 억제하는 변속기용 유압제어장치에 관한 것이다.The present invention relates to a hydraulic control device for a transmission, and more specifically, to a hydraulic control device for a transmission that improves drive response and suppresses drive loss by simplifying the hydraulic circuit and operating structure.
일반적인 습식 더블 클러치 변속기의 유압 제어 시스템의 경우, 엔진출력과 연결된 상시 구동 기계식 오일 펌프를 적용하여 유량 및 유압을 생성하며, 시스템에서 요구되는 유압은 레귤레이터 밸브와 같은 압력 제어 밸브를 적용하여 생성하여 기어 변속 실린더 및 듀얼클러치 피스톤을 제어하는 압력으로 사용된다. In the case of the hydraulic control system of a typical wet double clutch transmission, the flow rate and hydraulic pressure are generated by applying a constantly running mechanical oil pump connected to the engine output, and the hydraulic pressure required by the system is generated by applying a pressure control valve such as a regulator valve to control the gear. It is used as pressure to control the shifting cylinder and dual clutch piston.
즉, 상시 구동인 기계식 오일펌프에서 생성된 오일은 레귤레이터 스풀밸브와 라인압제어 솔레노이드 밸브에서 압력제어 되어 라인압을 생성하고, 라인압을 활용하여 기어변속용 솔레노이드 밸브 4개소와 시프트밸브 및 셀렉트 밸브용 스풀밸브의 조합으로 기어변속 유압을 제어하며, 윤활제어용 솔레노이드 밸브와 스풀밸브로 클러치 및 기어 각부 윤활을 제어하고, 가장 중요한 클러치 유압은 솔레노이드밸브와 압력제어 스풀밸브 조합으로 클러치압을 제어한다. 여기서 솔레노이드 밸브 & 스풀밸브 유압제어 및 기능안전을 유압라인으로 구현하기 위해 매뉴얼밸브, 윤활제어밸브, 기어변속밸브와 상호 연계가 되어 각 라인의 유압상황을 고려한 유압라인이 구성되어 복잡하게 연계되어 있다.In other words, the oil produced by the mechanical oil pump, which is always in operation, is pressure controlled by the regulator spool valve and the line pressure control solenoid valve to generate line pressure, and the line pressure is used to control four solenoid valves for gear shifting, shift valves, and select valves. Gear shifting hydraulic pressure is controlled by a combination of spool valves, lubrication of clutch and gear parts is controlled by lubrication control solenoid valve and spool valve, and the most important clutch hydraulic pressure is controlled by a combination of solenoid valve and pressure control spool valve. Here, in order to implement hydraulic control and functional safety of solenoid valves & spool valves through hydraulic lines, they are interconnected with manual valves, lubrication control valves, and gear shift valves to form complex hydraulic lines that take into account the hydraulic conditions of each line. .
한편, 종래의 파킹기구는 운전자 변속레버의 파킹조작력이 매뉴얼 컨트롤 레버와, 매뉴얼 컨트롤 샤프트와, 디텐트 레버 어셈블리와, 파킹로드 어셈블리와, 파킹 스프라그 순으로 작동하여 파킹 락 기어에 전달된다.Meanwhile, in a conventional parking mechanism, the parking operation force of the driver's shift lever is transmitted to the parking lock gear by operating in the order of the manual control lever, manual control shaft, detent lever assembly, parking rod assembly, and parking sprag.
종래 변속기용 유압제어장치는 메인 라인압 제어용 솔레노이드 밸브 및 스풀밸브, 기어변속 제어용 솔레노이드 밸브 및 스풀밸브, 시프트/셀렉트용 밸브, 윤활 제어용 솔레노이드 및 스풀밸브 등 많은 밸브들의 회로에 구비됨으로써, 구동손실 및 누유손실을 피할수 없는 구조이다. 또한, 솔레노이드 단품 및 기능안전/제어기술 등의 부족으로 기어변속, 클러치제어, 윤활제어 라인이 서로 복잡하게 연계되어 고장 발생시 문제요소를 밝히는데 어려움이 많다. 따라서, 이를 개선할 필요성이 요청된다.Conventional hydraulic control devices for transmissions are provided in the circuit of many valves, such as solenoid valves and spool valves for main line pressure control, solenoid valves and spool valves for gear shift control, shift/select valves, and solenoids and spool valves for lubrication control, thereby reducing driving loss and It is a structure in which leakage loss cannot be avoided. In addition, due to the lack of solenoid components and functional safety/control technology, gear shifting, clutch control, and lubrication control lines are complexly linked to each other, making it difficult to identify problem factors when a failure occurs. Therefore, there is a need to improve this.
