    Abstract: Hydraulic control apparatus includes a belt-drive CVT, a pressure regulator valve (P.REG.V) regulating the oil pressure produced by an oil pressure source, a controller programmed to develop a transmission control signal, a transmission actuator driven based on the signal, and a transmission control valve actuated by the actuator. There are provided a first oil passage for supplying an oil pressure regulated by the P.REG.V, a second oil passage for supplying the oil pressure regulated to a primary pulley cylinder chamber of the CVT and draining the oil pressure therefrom, a third oil passage for draining the oil pressure within the cylinder chamber, and a fourth oil passage downstream of the P.REG.V. The third and fourth oil passages are connected to supply an oil pressure to the cylinder chamber and establish a minimum oil pressure required for clamping the belt depending on reduction of the oil pressure within the cylinder chamber.

    Abstract: A lock-up control device comprises an inlet circuit which supplies oil to a torque converter chamber, an outlet circuit which discharges oil from the torque converter chamber, a signal output circuit which outputs a signal pressure according to a required engaging capacity of a lock-up clutch, and a lock-up control valve which outputs a lock-up control pressure according to the signal pressure from the signal output device. A lock-up control pressure which is fed back is input to the lock-up control valve so as to decrease the lock-up control pressure, and the pressure of the inlet circuit and pressure of the outlet circuit are input to the lock-up control valve so as to increase the lock-up control pressure. In this way, the pressure in the converter chamber is accurately reflected, and the lock-up control pressure is controlled so that a pressure differential between the lock-up control pressure and the torque converter chamber is a desired value.

    Abstract: A lock-up control device controls a lock-up clutch in a torque converter. The lock-up clutch is engaged by supplying a lock-up control pressure. The torque converter transmits torque via oil in a torque converter chamber when the lock-up clutch is disengaged, and transmits torque directly when the lock-up clutch is engaged. In the lock-up state, the oil pressure in the torque converter chamber is decreased by discharging oil in the torque converter chamber. By providing a circuit which leads oil discharged from the torque converter chamber to a lubricating part of the transmission, the balance between the inflowing oil amount and outflowing oil amount is improved, and oil insufficiency is prevented.

    Abstract: A belt-type continuously variable transmission having a forward clutch is incorporated with a speed-changing hydraulic pressure control system. The control system includes an engaging pressure regulating device for outputting an engaging pressure for the forward clutch. An electronically controlled hydraulic pressure control valve is provided to output a signal pressure which is able to cause the engaging pressure regulating device to set the engaging pressure. A control unit is provided to output a control command signal to the hydraulic pressure control valve, the control command signal causing the hydraulic pressure control valve to output the signal pressure. Here, the engaging pressure regulating device is arranged to output a minimum value of the engaging pressure in response to a maximum value of the signal pressure from the hydraulic pressure control valve, and to output a maximum value of the engaging pressure in response to a minimum value of the signal pressure.
