Description

차량용 자동 무단 변속 장치Automotive Continuously Variable Transmission

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명을 이용한 차량의 개략적인 유압 회로도.1 is a schematic hydraulic circuit diagram of a vehicle using the present invention.

Claims (1)

엔진(1)에 연결된 가변 용량형 유압 펌프(2)와, 그 유압 펌프에 연결된 방향 전환 밸브(6) 및, 상기 유압 펌프로 부터 방향 전환 밸브를 통하여 유압을 공급 받아 차륜(10)을 구동시키는 유압 모우터(7)로 이루어진 통상의 유압 구동 차량의 자동 무단 변속 장치에 있어서, 상기 유압 펌프(2)의 토출량을 조절하는 모우터(4)를 상기 유압 펌프(2)에 설치하고, 상기 유압 펌프(2)의 토출축 유압을 감지하는 토출측 유압 센서(16)를 상기 토출측에 설치하며, 엔진(1)의 출력에 의해 구동 되도록 통상적으로 설치된 발전기(5)에서 발생되는 전류의 세기와 상기 유압 센서(16)에서 감지된 토출측 유압의 조건들에 따라 상기 모우터(4)의 회전을 제어하는 모우터 제어 유니트(15)를 상기 모우터(4), 발전기(5)및 토출측 유압 센서(16)와 전기적으로 연결하여 구성된 것을 특징으로 하는 차량용 자동 무단 변속 장치.A variable displacement hydraulic pump 2 connected to the engine 1, a directional valve 6 connected to the hydraulic pump, and hydraulic pressure are supplied from the hydraulic pump through the directional valve to drive the wheel 10. In the automatic continuously variable transmission of a conventional hydraulic drive vehicle comprising a hydraulic motor (7), a motor (4) for adjusting the discharge amount of the hydraulic pump (2) is provided in the hydraulic pump (2), and the hydraulic pressure The discharge side hydraulic pressure sensor 16 for detecting the discharge shaft hydraulic pressure of the pump 2 is installed on the discharge side, and the strength of the current generated by the generator 5 normally installed to be driven by the output of the engine 1 and the hydraulic pressure The motor control unit 15 for controlling the rotation of the motor 4 according to the conditions of the discharge side hydraulic pressure sensed by the sensor 16 is connected to the motor 4, the generator 5, and the discharge side hydraulic sensor 16. ) Is electrically connected Automatic continuously variable transmission for vehicles. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
