摘要： A hydraulic power transmission device includes a toroid portion, a turbine hub, and a lock-up device. The toroid portion includes a pump impeller and a turbine runner. The turbine hub is engaged with an input shaft of a transmission and holds the turbine runner. The lock-up device is installed so that it engages and disengages freely and it mechanically transmits to the turbine hub rotation that is transmitted from a drive power source. The toroid portion and the lock-up device overlap in the axial direction. Because the toroid portion and the lock-up device overlap in the axial direction, the size of the hydraulic power transmission device in the axial direction can be reduced, and the hydraulic power transmission device can be made more compact.

摘要： An output of an internal combustion engine is transmitted to an output shaft by controlling a control motor to change a rotation speed output from the engine without speed steps via power distribution planetary gear. An output of a drive motor is input to the output shaft by changing the speed into two-step decelerated rotation by means of an automatic transmission. The transmission produces a desired torque by decelerating the speed by a large degree when a vehicle speed is low, and produces a desired number of revolutions by decelerating the speed by a small degree when the vehicle speed is high.

摘要： A continuously variable transmission is switchable between the low and high modes by changing engagement between two clutches. A sensor shoe which moves in association with a movable sheave of a primary pulley is provided with an indent and a protrusion formed at different locations on the sensor shoe. In addition, indents are formed on a spool of a low-high control valve. An interlock rod is provided between the sensor shoe and the low-high control valve. In a predetermined pulley-ratio region in the low and high modes, for example, on a low pulley-ratio side, as the movable sheave moves to the O/D side a base end of the interlock rod rides on the upper surface of the sensor shoe while its opposite end is engaged within one of the indents, thus mechanically locking the low-high control valve. In this way, switching between the low and high modes due to selective engagement of the low and high clutches can be inhibited.

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.
