摘要： A fluid pressure control valve for a hydraulic actuator has a valve body having a valve bore and a fluid port for discharging a fluid toward the hydraulic actuator, and a spool slidably received in the valve bore. The spool has a cylindrical spool section slidably fitted in the valve bore for closing the fluid port and a tapered spool section having a conical shape for opening the fluid port through annular open clearance of a variable area between the concial surface of the spool and the cylindrical surface of the valve bore. Between the cylindrical ad tapered spool sections, there is formed an annular groove or an annular face forming a step for preventing particles of dust suspended in the fluid from being bitten between the tapered spool section and the cylindrical surface of the valve bore by traping the particles. Furthermore, a radial groove is formed in a side wall of the fluid port in order to prevent a sudden change in the opening area which would be otherwise caused by an abrupt change of the spool contour due to the annular groove or the annular face.

摘要： According to a hydraulic pressure control system for a continuously variable transmission embodying the present invention, a hydraulic fluid pressure supplied to pulleys is increased temporarily during a transient period where the transmission upshifts from a reduction ratio to a smaller reduction ratio as a result of a predetermined movement of a manual selector valve. The level of the hydraulic fluid pressure is allowed to return to the previous low level after the transient period.

摘要： Normally a first target value is given and a reduction ratio of the continuously variable transmission is adjusted in such a direction as to bring the actual value into agreement with the first target value. However, when a predetermined heavy load condition on an engine is detected, a second target value is immediately given and the reduction ratio of the continuously variable transmission is adjusted in such a direction as to bring the actual value into agreement with the second target value. Subsequently, when a deviation of the actual value from the second target value becomes less than a predetermined value, a third target value is given and the reduction ratio of the continuously variable transmission is adjusted in such a direction as to bring the actual value into agreement with the third target value.

摘要： A pair of friction wheels gripped between an input disk and output disk facing each other on a rotation shaft of a friction wheel continuously variable transmission, are supported by a pair of supporting members each comprising a supporting shaft. An end of the supporting shaft of one supporting member and an end of the supporting shaft of another supporting member are joined by a link. The center of the link is supported free to pivot by a pin. The link supports the supporting member against an outward force exerted by the input disk and output disk on the friction wheels in a direction away from the rotation shaft. The link and supporting shaft are joined by inserting a joint into an engaging hole of the link. The shapes of the outer circumferential surface of the joint and inner circumferential surface of the engaging hole are set so that the force exerted by the joint on the link due to the action of the outward force does not generate a moment assisting inclination when the link inclines.

摘要： A control for a continuously variable transmission for quick downshifting to establish an effective engine brake running of an automotive vehicle, comprises a shift actuator, a shift operating mechanism for effecting a shifting in reduction ratio of the continuously variable transmission in response to a change in operating position of the shift actuator, and a control unit for varying a speed at which the shift actuator changes its operating position when a manually operable valve is placed at a L range position and an engine throttle valve is fully closed. More specifically, the shift actuator changes its operating position at a higher speed for quick downshifting to a reduction ratio suitable for an effective engine brake running.

摘要： A control for a continuously variable transmission provides an improved transient performance by restraining proportional and integral terms when an error exceeds a predetermined value range. This is effective in suppressing an overshoot in driver pulley revolution speed in approaching to its target speed. This control is provided with a safeguard against break down of a vehicle speed sensor such that the above mentioned restrain is removed when the vehicle speed indicative signal should drop to zero during running of the vehicle.

摘要： A control system for a continuously variable transmission for a vehicle, includes a hydraulically operable driver pulley, a follower pulley, a transmission V-belt tensioned between the driver and follower pulleys, and means, including a shift actuator and a shift control valve, for hydraulically controlling a reduction ratio between the driver and follower pulleys. In order to provide inproved shift response of the transmission upon depressing an accelerator pedal after a quick brake state of a vehicle where the vehicle wheels are locked, a position of a movable conical disk of the driver pulley which it would assume after initiation of the quick brake state is determined by arithmetic operation, and a shift actuator is driven toward a position thereof corresponding to the position assumed by the driver pulley so that the V-belt is tensioned between the driver and follower pulleys and conditioned to be ready for torque transmission.
