摘要： This invention relates to a belt driven continuously variable transmission having a pressure regulating cam mechanism giving a pulley an axial force which corresponds to transmission torque and eliminates torque transmission by friction between a pressure regulating cam and a fixed race. The stationary sheave, whose outer surface is supported, with rotation free at a case, by a bearing and whose inner side encloses the pressure regulating cam mechanism, has a circular hub elongating axially to the back side of the stationary sheave. Therefore, torque from the engine is transmitted to the fixed race of the regulating cam mechanism through an input member, and further transmitted to the stationary sheave through a roller and a movable race of the regulating cam mechanism. Consequently, the stationary sheave is supported at the case by the bearing and the radial load does not work on the pressure regulating cam mechanism. Therefore, the axial force generated by the pressure regulating cam mechanism can be set to correspond to the torque from the engine side without getting any influence from the torque transmission by friction.

摘要： A manual speed selector of an automatic vehicle transmission in which a line pressure is supplied from a manual valve capable of being changed over by a shift lever to control a plurality of solenoid valves so as to selectively supply hydraulic pressure to frictional engagement devices by shift valves. The shift lever can be moved between an automatic shift mode position and a manual shift mode position, and a transitive position is provided between these two mode positions. At the transitive position, the manual valve is set in a position such as to supply hydraulic pressure to set a neutral state based on the control of the solenoid valves. The shift lever can be immediately moved from this position to directly select any speed in the automatic shift mode or the manual shift mode. The above solenoid valves, a hydraulic control solenoid valve and a lock-up clutch engaging solenoid valve are controlled to enable rapid shifting in the manual shift mode as well as smooth shifting in the automatic shift mode.

摘要： One of bolt section or a nut section on a ball screw devices, or nut sections (for example) are connected to gear sections axially movable, while the bolt sections are connected to a stationary element, so that relative rotation is given to the bolt section and the nut section to adjust movable sheaves. Between another of the bolt section or the nut section on the ball screw devices, or the bolt sections (for example) and the stationary element, adjustable retainers are installed without axial move being allowed, and holding apparatus to hold the retainers at required position is installed with the retainers. Due to the above, initial tension and position of the belt are adjusted and determined by varying the nut sections in axial direction for the bolt sections. It is possible to perform this adjustment after the assembly is completed.

摘要： This invention relates to a belt driven continuously variable transmission having a pressure regulating cam mechanism giving an axial force corresponding to the transmission torque to a pulley and preventing too much belt pressing force. A retainer is fixed on a boss section of a stationary sheave and a spring made of multiple disc springs is situated on the outer surface of a boss section of a movable sheave for contact the retainer. A spring apparatus is composed of the retainer and the spring. Accordingly, at the decelerating range with large shifting ratio, besides the axial force made by the pressure regulating cam mechanism, the spring apparatus generates pressing force by contacting the retainer and maintains the belt holding force. When the shifting ratio is small, the spring returns to its natural length and disengages from the retainer.

摘要： A continuously variable speed transmission having a belt drive continuously variable speed transmission in which a belt is wrapped around primary and secondary pulleys each supported on a shaft and each consisting of a pair of sheaves capable of relatively moving axially, and a forward/reverse rotation changeover mechanism. The belt drive continuously variable speed transmission is provided with a pressure adjusting cam mechanism for applying an axial force corresponding to a transmitted torque to at least one of the pulleys, ball screw mechanisms for axially moving the movable sheaves of the pulleys. A fluid torque converter is disposed on the transmission upstream side of the primary pulley. In the belt drive continuously variable speed transmission, the pressure adjusting cam mechanism produces and axial force corresponding to the transmitted torque to clamp the belt, and the power is transmitted by the effect of this clamping force without belt slip. If at the time of vehicle starting the torque of the fluid torque converter is increased, the pressure adjusting cam mechanism produces a larger axial force corresponding to the increased torque, thereby clamping the belt by a larger force to prevent the belt from slipping during transmission of power. This large belt clamping force is produced for only a short time for vehicle starting. As the torque of the fluid torque converter is reduced to a coupling range, the axial force produced by the pressure adjusting cam mechanism is correspondingly reduced automatically. The belt is clamped by a reduced axial force for a greater part of the operating time.

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.
