摘要： A hydraulic control system for a four-wheel drive torque transfer mechanism for a vehicle, including an automatic transmission, a transfer mechanism having a two-wheel drive direct-coupling gear (H.sub.2), a four-wheel drive direct-coupling gear (H.sub.4) and a reduced-speed four-wheel drive gear (L.sub.4) and a hydraulic control circuit for controlling the transmission and the transfer mechanism. The transfer mechanism includes a reduction gear mechanism, a first output shaft, a second output shaft connected to the first output shaft by means of a linkage, a four-wheel drive clutch for rotatably connecting and disconnecting the first and second output shafts, a direct-coupling clutch for connecting and disconnecting the input shaft of the reduction gear mechanism and the first output shaft and a reduction brake for shifting the reduction gear mechanism into the reduced-speed mode. The hydraulic control circuit includes a modulator valve capable of supplying a fluid of a reduced pressure when the transfer mechanism is established in the four-wheel drive direct-coupling gear so that the coupling torque of the four-wheel drive clutch is reduced and supplying a fluid of an increased pressure when the transfer mechanism is established in the reduced-speed four-wheel drive gear so that the coupling torque of the four-wheel drive clutch is increased.

摘要： An automatic transmission for motorcar of the type including a main transmission and an auxiliary transmission is disclosed. The auxiliary transmission has a plurality of speed changing stages and when it assumes a certain lower speed stage, any speed changing to higher speed stage is inhibited in the main transmission. The main transmission is provided with a solenoid valve which makes it possible to carry out speed changing to higher speed stage when it is turned on, while the auxiliary transmission is provided with a hydraulic control device which is communicated with a hydraulic servo via a hydraulic passage. The hydraulic servo is operatively associated with a speed reduction frictional engagement element which allows the auxiliary transmission to assume a certain lower speed stage. The solenoid valve is electrically connected to a pressure switch which is so constructed that it is turned off when the hydraulic servo is supplied with hydraulic oil and it is turned off when hydraulic pressure is released from the hydraulic servo. When the auxiliary transmission assumes a certain lower speed stage, the hydraulic servo is supplied with hydraulic oil and the solenoid valve is turned off. Thus, any speed changing to higher speed stage is inhibited in the main transmission.
