Abstract

본 발명은 차량의 변속기와 프로펠러축 사이에 실치되어 진흙길 또는 눈길에서 구동륜간의 차동 공회전을 운전자의 필요시 스위치 조작에 의해 제한하므로서 안정된 주행이 이루어지도록 한 자동 변속기용 차동장치의 구동륜 공회전 방지장치로 이를 실현하기 위해 차동장치의 차동장치 케이스에 내장된 사이드 기어가 설치되는 양측 출력축에 형성된 스플라인 기어에 스플라인 결합으로 복수개 실치되는 클러치부의 마찰수단과; 상기 클러치부의 일측 쳄버에 유압의 충진시 가압하도록 설치된 피스톤의 가압수단과; 이 피스톤이 내장된 쳄버에 오일이 충진될 때 유압이 발생하도록 차동장치의 케이스에 형성된 제1유로의 공급수단과; 이 제1유로에 연결되도록 자동 변속기 케이스에 내장된 오일 펌프와 연통 설치되면서 제2유로와 연결 설치되는 밸브 바디의 유로 제어수단과; 상기 밸브 바디에 연결되어 소정의 차속 이상에서도 오프(OFF) 가 되도록 하는 차동 제한 콘트롤 솔레노이드 밸브의 조정수단과; 상기 차동 제한 콘트롤 솔레노이드 밸브를 제어하는 트랜스밋션 컨트롤 유니트에 연결되어 운전자에 의해 조작되는 홀딩 스위치의 통전수단을 포함하여 이루어지고 있다.The present invention is a drive wheel idle prevention device of a differential device for an automatic transmission which is installed between a vehicle's transmission and a propeller shaft to stabilize driving by limiting differential idling between driving wheels on a muddy road or snow road by a switch operation if necessary by the driver. Friction means for mounting a plurality of splines by spline coupling to spline gears formed on both output shafts on which side gears are mounted; A pressurizing means of a piston installed to pressurize the hydraulic chamber to one side chamber of the clutch unit; Supply means for supplying a first flow path formed in a case of the differential device so that hydraulic pressure is generated when oil is filled in a chamber in which the piston is built-in; Flow path control means of the valve body connected to the second flow path while being installed in communication with the oil pump embedded in the automatic transmission case to be connected to the first flow path; An adjustment means of a differential limit control solenoid valve connected to the valve body so as to be turned OFF even at a predetermined vehicle speed or more; It is connected to the transmission control unit for controlling the differential limit control solenoid valve, it comprises a power supply means of the holding switch operated by the driver.
