摘要： A one-way brake having end bearings the support wall of each of which is protruded at the inner race side portion thereof in the outward direction with respect to a space between inner and outer races from that surface of the support wall which is contacted by a support means connected to the outer race, to thereby increase the area of that portion of the inner race which is in sliding contact with an inner rib of the support wall. Accordingly, the wear resistance and stiffness of the end bearings can be increased without increasing an attaching space.

摘要： A belt type continuously variable transmission (CVT) and a planetary gear unit are combined in a continuously variable transmission system for an automobile to deliver an output from the output shaft in the normal and reverse directions with a neutral position therebetween. A control mechanism with a hydraulic circuit controls hydraulic pressure of primary and secondary hydraulic servos for controlling axial forces applied to respective primary and secondary pulleys of the belt type continuously variable transmission. When an axial force difference is produced between the primary pulley and the secondary pulley, the belt type continuously variable transmission changes its speed corresponding to a torque transmission direction and normal and reverse rotation directions. When axial forces of the primary and secondary pulleys become equal, then the belt type continuously variable transmission self-converges so that the output shaft has zero rotation and is stably held at the neutral position without a driving starter device and without a normal and reverse rotation switching device.

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： 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： An automatic transmission for a vehicle a shift pattern, restricting the movement of a shift lever, including at least an H-shaped portion. When the shift lever has been moved to any shift position of the pattern, a range and a gear ratio which corresponds to the shift position are selected. When the shift lever is released from the shift position in the lowest stage, the gearing is shifted to the ratio which is higher than the lowest stage by one step. When the shift lever is released from the shift position in the highest stage, the gearing is shifted to the ratio which is lower than the maximum stage by one step. When the shift lever is moved to a position intermediate the shift positions, the range and the gear ratio which correspond to the shift position before the movement can be maintained or the automatic transmission range can be established. The switching between the previous stage maintaining function and the automatic transmission drive mode selection function is made by determination of whether or not the driver is operating the shift lever.
