Abstract
PURPOSE: To automatically control a subspeed change gear in accordance with an operational state in the above described device with the subspeed change gear, by arranging a hydraulic control circuit device for a planetary geared subspeed change gear in a subcasing.
CONSTITUTION: Though pressure oil is regulated by a pressure-regulating valve 113 and fed to a port 127 of a selector valve 126 by a hydrauric pump 101 driven by an output power shaft 5 when a vehicle is in travelling motion, the pressure oil is relieved to the side of a relief oil line 137 when a solenoid 134 is not conducted to flow an electric current and this causes the disconnection of supply of the pessure oil to a cylinder chamber 45, accordingly a piston member 40 is pressed by a belleville spring 50 and a friction engaging member 21 is friction engaged to a ring gear 23, then a planetary gear mechanism is locked to directly couple an input shaft 11 to an intermediate shaft 4. Electric conduction to the solenoid 134 causes the pressure oil to flow into the cylinder chamber 45, then the planetary gear mechanism is unlocked through the leftward motion of the pressurized piston 40 to perform the speed change operation. In this way, a subspeed change gear can be automatically controlled.
