摘要： The transmission comprises a hydraulic power transmission device, a V-belt stepless shifter and a planetary gear train. At restart time when the vehicle is at rest with the V-belt stepless shifter in high gear, the hydraulic power transmission device is operated to shift for providing a relatively high torque ratio, rather than the V-belt stepless shifter. A smooth restart is thus made possible. In addition, the planetary gear train permits the shifter smoothly to switch between forward and reverse. Both features meet the transmission needs of all vehicles.

摘要： An infinitely variable transmission has a gear neutral (GN) point and serves as an output member by torque circulation. When a pulley ratio thereof is within a predetermined range from the GN point, a coasting state occurs which may hinder smooth torque transmission based on the transmission efficiency and generate a great engine braking effect (failure in the transmission resulting from the coasting state) based on a large gear ratio. When the pulley ratio assumes a predetermined value that may cause failure in transmission resulting from the coasting state, upon release of the accelerator pedal, an electronic throttle system performs control such that the engine outputs a predetermined torque. Thus a positive driving state is always established. In this state, the continuously variable transmission (CVT) is shifted in the upshift direction to escape rapidly from a range defined by the pulley ratio of the predetermined value.

摘要： A continuously variable transmission system includes a belt type continuously variable transmission unit which, in turn, is composed of a primary pulley and a secondary pulley wherein the torque transmitting direction is switched by torque circulation in changeover between forward and reverse travel. When a low mode is selected in a D range, a somewhat higher hydraulic pressure from a regulator valve is supplied, through a manual valve, to a secondary hydraulic servo, which moves one sheave of the secondary pulley, and a somewhat lower hydraulic pressure from a ratio control valve is supplied to a primary hydraulic servo which moves one sheave of the primary pulley. When the D range is switched to R range by the manual valve, the supplies of the above hydraulic pressures are reversed. With this arrangement, the relative axial forces on the pulleys are changed in switching between forward and reverse travel.

摘要： A continuously variable transmission system includes a belt type continuously variable transmission unit (CVT) wherein the direction of torque transmission is switched by torque circulation between a low mode and a high mode accompanied by a change in the axial forces on the pulleys of the CVT. In the Low mode of the D range, a comparatively high hydraulic pressure from a regulator valve is supplied to a Low clutch hydraulic servo via a low-high shifting valve and to a secondary hydraulic servo. In addition, a comparatively low hydraulic pressure from a ratio control valve is supplied to a primary hydraulic servo. These oil pressure feeds are reversed by the switching of the low-high shifting valve.

摘要： A continuous V-belt transmission comprising: a primary pulley and a secondary pulley individually including two sheaves supported on shafts and made axially movable relative to each other; a belt made to run on the two pulleys; mechanical actuators individually including first members and second members for moving the movable sheaves of the two pulleys on the basis of the relative rotations of the two members: and pressure regulating mechanisms for applying an axial force corresponding to a transmission torque to at least one of the pulleys. In an unshifted state, the rotations of the pulleys are transmitted from the externally threaded portions integrated with the movable sheaves to the carriers of the planetary gear mechanisms so that they are transmitted through the ring gears to toe internally threaded portions on the basis of the sun gears being stopped. At this time, the externally threaded portions and the internally threaded portions are rotated integrally with the pulleys at the same r.p.m. If the sun gears are rotated through the shafts by the shift motor, the externally threaded portions and the internally threaded portions are rotated relative to each other to effect the shifting operation. At this time, the stroke of a ball screw unit is caused to match the stroke of the movable sheaves by non-circular gears.
