摘要： A control system for a toroidal type continuously variable transmission which incorporates a toroidal continuously variable gear mechanism comprising an input and an output toroidal disk and a roller disposed between the input and output toroidal disks and continuously varies a gear ratio according to inclinations of the roller actuates a stepping motor, when a specific driving condition which causes the continuously variable transmission to switch between a first and a second control mode and directional reversal of torque transmission through the toroidal continuously variable gear mechanism occurs with a result of causing a shift of the roller from one side to another side of the neutral position, to operate a double-slider shift valve to cause the shift of the roller in advance.

摘要： A continuously variable transmission has springs, which urge the movable sheaves of primary-side and secondary-side pulleys, set to achieve a pulley ratio r.sub.1 approximate to or within a predetermined range of a neutral pulley ratio r.sub.N so that a vehicle takeoff response delay is eliminated when the driver shifts the transmission from a vehicle stop range (the P or N range) to the drive range (D range). This setting prevents a vehicle from moving backward when the driver shifts from the vehicle stop range to the D range immediately after starting the engine. The pulley ratio r.sub.1 can be achieved either before or after the minimum required fluid pressure is supplied.

摘要： A continuously-variable-ratio transmission ("CVT") of the band-and-sheave type capable of "torque control", so that what the operator demands, by movement of the accelerator pedal or other control member, is a particular driving torque applied to the ratio-varying components ("variator") A connection (21, 22) between at least one of the variator sheaves (3, 4) and its shaft (5) is torque-sensitive, so that torque at that sheave generates an axial force which is a function of the magnitude and direction of the torque to which the sheave is subjected. Examples are described in which the operating axial load, applied to the variator pulley units, comprises two parts--a first part to maintain traction between sheaves and band, and a second part related to the applied torque--and a variator using more than one band.

摘要： A transmission includes a sub-transmission mechanism, a variator having lower shift responsiveness than the sub-transmission mechanism, and a controller configured to carry out a coordinated shift for changing a speed ratio of the variator in a direction opposite to a changing direction of a speed ratio of the sub-transmission mechanism as the sub-transmission mechanism is shifted so that a through speed ratio reaches a target through speed ratio. The controller sets a target speed ratio of the sub-transmission mechanism on the basis of the target through speed ratio and an actual speed ratio of the variator in carrying out the coordinated shift.

摘要： When a through speed ratio, which is an overall speed ratio of a variator and a subtransmission mechanism, varies from a larger speed ratio than a mode switch speed ratio to a smaller speed ratio than the mode switch speed ratio, a gear position of the subtransmission mechanism is changed from a first gear position to a second gear position and the speed ratio of the variator is modified to a large speed ratio side. The mode switch speed ratio is set midway between a low speed mode Highest speed ratio and a high speed mode Lowest speed ratio.

摘要： In a controller of a vehicle transmission, the transmission includes a continuously variable transmission 3 and a planetary gear mechanism 4 and is coupled to an output of an engine 1. The transmission includes a first shift mode using only the continuously variable transmission 3 and a second shift mode using in combination the continuously variable transmission 3 and the planetary gear mechanism 4. The controller determines the shift mode based on load of the engine 1 according to a required output and an input/output revolution speed ratio γ of the continuously variable transmission 3, and switches between the above two shift modes at the predetermined input/output revolution speed ratio.

摘要： In a neutral N control for substantially equalizing axial forces to act on two pulleys, a belt type continuously variable transmission (CVT) self-converges into the gear neutral point (GN) at which the output shaft RPM takes the value 0. When the convergence is made to the GN point to establish a no-load state, the CVT establishes a force F.sub.A to converge into a pulley ratio of 1.0, in which it is stabilized by itself. A converging force F.sub.N to the GN point and the force F.sub.A toward the pulley ratio of 1.0 are repeated in a vortex shape in the load state and in the no-load state to establish a creep force. This creep force can be modified by generating a force F.sub.O against the force F.sub.A.

摘要： In a CVT transmission with planetary gear operation in forward, zero and reverse directions, reduction in CVT secondary/primary pulley ratio is inhibited when the pulley ratio is less than a set pulley ratio which is higher than the pulley ratio producing zero output rotation (a gear-neutral state). In a ratio region below the set pulley ratio, a movable sheave of a primary pulley is moved to an O/D side. The amount of the movement is detected by a sensor shoe (detecting means) which is associated with the movable sheave. A ratio sensing valve (inhibition means) associated with the sensor shoe, in turn, clogs a port, halting a hydraulic pressure supplied by a primary regulator valve. As a result, no hydraulic pressure is supplied to the second hydraulic chamber by way of a down-shift relief valve, a manual valve or a low-high control valve, inhibiting a down shift.
