摘要： A lockup control valve is provided to control the discharge from the lockup clutch during clutch engagement and a solenoid valve to supply the control pressure to the lockup control valve. The aforesaid lockup control valve has a face on which the oil supply pressure acts during lockup clutch engagement, an opposing face of equal area on which the lockup clutch discharge pressure acts, a face on which the supply pressure from the aforesaid solenoid valve acts, and an opposing face on which a constant pressure acts. The hydraulic controlling system controls the discharge pressure of the lockup clutch during lockup clutch engagement according to the control pressure from the solenoid valve. This maintains a constant relationship between the solenoid pressure and the lockup clutch capacity (pressure difference) and permits precise slip control even if the oil pressure supplied to the lockup clutch fluctuates.

摘要： Pulleys are provided with load cam mechanisms which exert axial forces corresponding to transmitted torque, and actuator means such as ball screw mechanisms which shift the movable sheaves of both pulleys in axial direction, wherein the axial forces occuring at the pulleys are carried by their shafts and do not act on the housing. A counter shaft is located between the primary and secondary shafts, the countershaft being rotated to drive the actuator means through gearing such as gearwheels, to alter the drive ratio. During power transmission, the axial forces acting on the movable sheaves of primary and secondary pulleys are converted into torque by the actuator means, where the torques are transmitted to the counter shaft in the form of counteracting torques, so that alteration of drive ratio can be made with slight effort on the counter shaft, equivalent ot the difference between the counteracting torques.By using a non-uniform cam mechanism for the actuator means, or by using non-circular gearwheels for the gearing, the displacements of the movable sheaves are matched with their proper displacements determined by the belt.

摘要： An end of a shaft member which is displaced and actuated in conjunction with a shift lever of a transmission presses and displaces a latch which is arranged in such a way as to be able to be displaced in an opposing direction against a cam surface of a cam which is formed on a fixed member to function like a wedge which wedges itself between said cam surface and latch, thereby making the latch engage teeth which are drivingly coupled to an output shaft of the transmission in a parking mechanism of a transmission. A cylindrical support portion is continuously extended from the cam surface so as to guide the end of the shaft member at the time when the end of the shaft member is disengaged from the area between the cam surface and latch.

摘要： A stepless belt transmission includes a working fluid control unit having a supply port for supplying working fluid to a hydraulic actuator, a discharge port for discharging the working fluid from the hydraulic actuator, a lead mechanism for changing the working fluid pressure internally of the hydraulic actuator by varying the opening degree of the supply port or discharge port in dependence upon vehicle running conditions, and a follow-up mechanism operatively associated with a movable flange displaced by the changed working fluid pressure to restore the port opening degree varied by the lead mechanism. It is possible to achieve highly sophisticated control of transmission ratio in dependence upon vehicle running conditions through a comparatively simple construction and on the basis of a simple control method in which the stroke of the lead mechanism is suitably regulated.
