Description
본 고안은 3개의 유성기어(planetary gear)와 5개의 마찰부재를 가진 유성치차를 이용하여 전진 5속, 후진 1속 자동변속기를 구현하고자 한 5단 자동 변속기에 관한 것이다.The present invention relates to a five-speed automatic transmission that attempts to realize a five-speed forward and one-speed automatic transmission using three planetary gears and five friction members.
일반적으로, 자동차의 자동 변속기는 토오크 컨버터와, 이 토오크 컨버터에 연결설치된 다단 변속기어 메카니즘, 오일펌프로부터 발생된 유압을 제어밸브를 통하여 자동차의 주행상태에 따라 변속기어 메카니즘의 어느 하나의 기어단을 선택하기 위한 유압작동 마찰부재를 작동시키는 유압제어 시스템을 포함하고 있다.In general, an automatic transmission of a vehicle uses a torque converter, a multistage gear mechanism connected to the torque converter, and hydraulic pressure generated from an oil pump to control one gear stage of the transmission gear mechanism according to the driving condition of the vehicle through a control valve. It includes a hydraulic control system for operating a hydraulically actuated friction member for selection.
상기 토오크 컨버터는 엔진의 크랭크축에 연결된 상태에서 구동되는 펌프 임펠러와, 변속기의 입력축에 연결된 상태에서 연동되는 터빈 런너와, 상기 펌프 임펠러와 터빈 런너 사이에 설치된 스테이터로 구성되어 있다.The torque converter is composed of a pump impeller driven in a state connected to the crankshaft of the engine, a turbine runner interlocked in a state connected to the input shaft of the transmission, and a stator installed between the pump impeller and the turbine runner.
이와 같은 구성의 토오크 컨버터는 엔진이 회전하면 펌프 임펠러내의 오일이 원심력에 의해 외주방향을 향하여 흐름이 발생하여 펌프 임펠러-터빈 런너-스테이터-펌프 임펠러로 흐르는 순환류가 발생하고 상기 오일이 펌프 임펠러로부터 터빈 런너로 유입될 때 오일펌프의 주속과 순환류가 합성된 방향을 가지고 있으므로 상기 터빈 런너의 베인에 부딪치는 충격력으로 인해 펌프 임펠러의 회전방향으로 밀림에 따라 회전력을 받게 된다.In the torque converter of this configuration, when the engine rotates, the oil in the pump impeller flows toward the circumferential direction due to the centrifugal force to generate a circulating flow to the pump impeller-turbine runner-stator-pump impeller, and the oil flows from the pump impeller to the turbine. Since the circumferential speed and the circulating flow of the oil pump have a combined direction when entering the runner, a rotational force is received as the pump impeller is pushed in the rotational direction due to the impact force that strikes the vane of the turbine runner.
자동 변속은 각 변속단마다 설치된 클러치 또는 킥 다운 브레이크 등의 마찰부재의 작동으로 유성기어장치에서 변속비가 바뀌어짐에 따라 이루어지며 상기 마찰부재는 유압제어 시스템을 이루는 다수개의 밸브들에 의해 유압의 흐름방향이 바뀌어 선택적으로 작동되게 된다.Automatic shifting is performed by changing the gear ratio in the planetary gear system by the operation of a friction member such as a clutch or a kick-down brake installed at each shift stage, and the friction member is operated by a plurality of valves forming a hydraulic control system. The direction is changed to activate selectively.
상기 유압제어 시스템은 오일펌프로부터 발생된 유압을 압력조절수단과, 변속레인지를 형성시켜 주는 자동·수동 변속 컨트롤수단과, 변속시 원활한 변속레인지를 형성하기 위해 변속감·응답성을 조절하는 유압 컨트롤수단과, 토오크 컨버터의 댐퍼 클러치의 작동을 조절하기 위한 댐퍼 클러치 콘트롤수단과, 각 마찰부재에 적절한 유압을 공급하기 위한 유압분배수단을 포함한다.The hydraulic control system is a pressure control means for the hydraulic pressure generated from the oil pump, an automatic and manual shift control means for forming a shift range, and a hydraulic control means for adjusting the shift feeling and response to form a smooth shift range during shifting. And damper clutch control means for adjusting the operation of the damper clutch of the torque converter, and hydraulic distribution means for supplying appropriate hydraulic pressure to each friction member.
그러나, 상기와 같은 기존의 자동차용 4속 자동변속기의 유압제어 시스템에 있어서는 다수개의 밸브들과 각 마찰부재들에 모두 드러이브 압이 공급되어 제어됨으로써 드라이브 압이 불안정하고 이로 인해서 작동의 신뢰성을 확보할 수 없었으며, 파킹 레인지에서 자동 트랜스밋션의 작동유체가 각 밸브들에 공급되지 않아 작동유체의 레벨을 체크할 수 없는 문제점이 있었다.However, in the hydraulic control system of the conventional four-speed automatic transmission as described above, the drive pressure is unstable because the drive pressure is supplied to the plurality of valves and each friction member to control the drive pressure, thereby ensuring reliability of operation. There was a problem that the working fluid of the automatic transmission in the parking range was not supplied to the valves so that the level of the working fluid could not be checked.
또한, 각각의 마찰부재들에 직접적으로 드라이브 압을 공급하여 제어하기 때문에 변속충격의 조절에 한계가 있고 이로 인해서 향상된 변속감은 물론 변속응답성을 얻을 수 없는 것이었다.In addition, since the drive pressure is directly supplied to each of the friction members to control the shift shock, there is a limit, and thus, the shift feeling and the shift response cannot be obtained.
그러나, 상기와 같은 기존의 자동차용 4속 자동변속기의 유압제어 시스템에 있어서는 다수개의 밸브들과 각 마찰부재들에 모두 드라이브 압이 공급되어 제어됨으로써 드라이브 압이 불안정하고 이로 인해서 작동의 신뢰성을 확보할 수 없었다.However, in the hydraulic control system of the conventional four-speed automatic transmission as described above, the drive pressure is supplied to and controlled by a plurality of valves and respective friction members so that the drive pressure is unstable, thereby ensuring reliability of operation. Could not.
또한, 상기에서와 같이 4속으로 이루어져 있으므로, 수동기어와 같이 전진 5속, 후진 1속을 구현할 수 없으므로 운전자의 기호를 충족시켜 주지 못하였다.In addition, since it consists of four speeds as described above, it was not possible to implement the 5 forward, 1 reverse speed like a manual gear, it did not satisfy the driver's preference.
본 고안에서는 상기에서와 같은 문제점을 해결하기 위하여 3개의 유성기어와 5개의 마찰부재를 이용하여 수동기어에서와 같은 전진 5속, 후진 1속의 자동변속기를 구현할 수 있도록 함으로써, 신뢰성 있는 자동변속장치의 제공 및 운전자의 기호를 충족시켜 줄 수 있도록 한 것이다.In order to solve the problems as described above, by using three planetary gears and five friction members, it is possible to implement an automatic transmission of 5 forward speeds and 1 reverse speed as in manual gears. It is intended to meet the needs of the driver and the driver.
