Abstract: PURPOSE: A fail safe hydraulic system of an automatic transmission is provided to realize a safe travel by preventing the occurrence of interlock in a power train regardless of the sticking position of a valve spool. CONSTITUTION: A second clutch(C2) and a first brake(B1) are supplied with the output pressure of a C2/B1 control valve(52) controlled by a C2/B1 control solenoid valve(50). The output pressure of the C2/B1 control valve is switched to two paths by a C2/B1 switch valve(54). One of the paths is communicated with the second clutch via a first fail safe valve(56) while the other path is communicated with the first brake via a second fail safe valve(58). The hydraulic pressure supplied to the second clutch is discharged via the C2/B1 switch valve and the fist fail safe valve. The hydraulic pressure supplied to the first brake is discharged via the C2/B1 control valve and the second fail safe valve. The output pressure of a C1 control valve(62) is applied to a first clutch via two paths. One of the paths is communicated with a first clutch(C1). The other path operates as a control pressure to second and third fails safe valves(58,64) and supplies hydraulic pressure to a first friction element via a first shuttle valve. Then, first and second brake pressures are released. The first brake pressure generated in the C2/B1 switch valve is supplied only when the second fail safe valve is switched over.

Abstract: 본 고안은 종래의 솔레노이드 취부구조가 솔레노이드 밸브 양측에 형성된 탭부에 볼트를 하나씩 삽입하게 되므로 밸브 하나당 볼트가 2개 필요할 뿐 아니라 이를 위한 공간이 필요하여 유로 구성에 상당한 제약이 따르는 문제점이 있기 때문에,
밸브바디에 상측으로 돌출된 돌출부를 형성하고, 상기 돌출부를 중심으로 솔레노이드 밸브를 배치하여 설치한 후, 상기 솔레노이드의 상면을 눌러주는 플레이트를 볼트로 상기 돌출부에 고정함으로써,
하나의 볼트만을 이용하여 2개의 솔레노이드 밸브를 취부시킬 수 있으므로 조립작업이 단순화되고 볼트가 밸브바디를 관통하지 않으므로 유로 형성시의 제약을 해소할 수 있는 솔레노이드 밸브 취부구조에 관한 것이다.

Abstract: PURPOSE: A hydraulic control system of an automatic transmission is provided to reduce the loss of the driving force of an engine and to improve fuel efficiency by reducing a discharge pressure of an oil pump when the throttle opening degree is low. CONSTITUTION: A hydraulic control system of an automatic transmission comprises a torque converter to convert torque by receiving the driving force of an engine, an oil pump to generate oil-hydraulic pressure, a pressure control unit to change line pressure by a transmission control unit depending on the throttle opening degree, a manual valve to change a speed range by operating with a shift lever, and a hydraulic distribution unit to supply the hydraulic pressure transmitted from the manual valve to respective friction elements. The pressure control unit consists of a regulator valve(7), a cutback valve(9), a solenoid valve(11), and a pressure modifier valve to supply oil-hydraulic pressure to the cutback valve. When the throttle opening degree is lower than a reference degree, line pressure is controlled depending on the rate of the oil-hydraulic pressure returning to an oil pan(15).

Abstract: PURPOSE: A hydraulic pressure controlling system increases a speed change sense by decreasing the pulsation of a hydraulic pressure provided to the first brake, even if an another accumulator is not installed. CONSTITUTION: An accumulator switch valve(30) is disposed between the second fail safe valve(28) and the second brake(B2) to use the accumulator for the second brake(B2) operating in a forward 2,4 grade among the friction factor as the accumulator for the first brake(B1) operating in a forward 1 grade and a backward speed change grade. The accumulator valve(30) is connected so that a hydraulic pressure provided to the first brake(B1) is provided to a second fail safe valve(28). Therefore, the accumulator used for the second brake(B2) is used for the first brake(B1) also. Thus, the hydraulic pressure controlling system increases a speed change sense by decreasing the pulsation of a hydraulic pressure provided to the first brake(B1), even if an another accumulator is not installed.
