摘要： In an infinite speed ratio transmission comprising a continuously variable transmission (2), reduction gear unit (3) and planetary gear set (5), the speed ratio of the continuously variable transmission (2) is controlled by a step motor (36). A range selected by a selector lever (86) is detected by a sensor (84). When the selected range has changed from a stationary range to one of a forward motion range and a reverse motion range, a microprocessor (80) first drives the step motor (36) to a predetermined position (S48, S54). Subsequently, by driving the step motor (36) to an operating position corresponding to a geared neutral point at which the output rotation speed of the infinite speed ratio transmission is zero (S51, S52, S53, S57, S58, S59), the undesirable effects of hysteresis occurring in a relation between the operating position of the step motor (36) and the speed ratio of the continuously variable transmission (2) according to a torque shift of the continuously variable transmission (2) are avoided.

摘要： An infinite Speed ratio continuously variable transmission comprises a power recirculation mode clutch (9) and direct mode clutch (10). At least one of the power recirculation mode clutch (9) and direct mode clutch (10) comprises an electromagnetic two-way clutch. The electromagnetic two-way clutch maintains the engaged state during excitation and can transmit drive force from both the drive side and non-drive side. On the other hand, when there is a change-over from the energized state to the non-energized state, a one-way clutch state is obtained wherein drive force is permitted only in the transmission direction of drive force in the instant of the change-over to non-excitation. When a drive force is input in the reverse direction to the drive force transmitted in the one-way clutch state, the one-way clutch state is disengaged, and the disengaged state of the clutch is maintained until subsequent re-excitation. Therefore, change-over of the clutch at the rotation synchronous point RSP where the power recirculation mode and direct mode are changed over, can be performed rapidly.

摘要： A creep torque is controlled in a non-finite speed ratio transmission device, wherein a planetary gear unit (5) varies a rotation direction of a final output shaft (6) according to a relative rotation of a toroidal continuously variable transmission (2) and fixed speed ratio transmission (3). The controller comprises a hydraulic cylinder (39) which varies the speed ratio of the toroidal continuously variable transmission (2) by driving a trunnion (23), a shift control valve (46) which supplies a hydraulic pressure to the hydraulic cylinder (30) according to a displacement position, a step motor (36) which displaces the shift control valve (46) according to a command signal, and a mechanical feedback member (35, 37, 38) which feeds back the speed ratio of the toroidal continuously variable transmission (2) to the shift control valve (46). The controller further comprises a sensor (83, 86) which detects a running state of a vehicle, a sensor (81, 82) which detects the real speed ratio of the continuously variable transmission (2), and a microprocessor (80) which outputs the command signal. When the vehicle running state corresponds to a predetermined state, the microprocessor (80) outputs a new command signal based on a required creep torque and the real speed ratio of the continuously variable transmission (2) to the step motor (36).

摘要： An infinite speed ratio continuously variable transmission is provided with a continuously variable transmission (2), fixed speed ratio transmission (3), planetary gear set (5), power recirculation clutch (9) and direct clutch (10). A target speed ratio of the infinite speed ratio continuously variable transmission is set based on a vehicle speed and an accelerator pedal depression amount. When the target speed ratio varies beyond a rotation synchronous point, a control unit (80) assigns an order of priority to control of the power recirculation clutch (9) and direct clutch (10), and control of the speed ratio of the continuously variable transmission (2), and thereby causes a real speed ratio of the infinite speed ratio continuously variable transmission to vary in the same direction until it reaches the target speed ratio (S21, S22, S31, S32, S121, S122).

摘要： A toroidal continuously variable transmission (1) comprises power rollers (18C, 18D, 20C, 20D) which transmit a torque between input disks (18A, 20A) and output disks (20A, 20B), and trunnions (104, 105, 114, 115) which drive the power rollers (18C, 18D, 20C, 20D) in a perpendicular direction to a rotation shaft (16A) according to a differential pressure between a first oil chamber (101) and a second oil chamber (102). When the second oil chamber (102) is at higher pressure than the first oil chamber (101), the toroidal continuously variable transmission (1) causes a downshift, and when the first oil chamber (101) is at higher pressure than the second oil chamber (102), the toroidal continuously variable transmission (1) causes an upshift. The first oil chamber (101) is connected to a first passage (176) and the second oil chamber (102) is connected to a second passage (177). A speed ratio control valve (70, 70A) controls a direction and a flowrate of the first passage (176) and the second passage (177). A pressure control valve (200, 210, 220, 40, 45, 41, 46) limits a maximum differential pressure of the first oil chamber (101) and the second oil chamber (102) when the transmission (1) causes a downshift to be less than a maximum differential pressure of the first oil chamber (101) and the second oil chamber (102) when the transmission (1) causes an upshift. This arrangement prevents a sharp downshift of the toroidal continuously variable transmission (1) due to a fault or incorrect operation.

摘要： A rotation clutch device rotates on an axis of an automatic transmission. The rotation clutch device comprises a clutch piston which slides around the axis of the automatic transmission for the engagement of the clutch device. First and second chamber are formed to slide the clutch piston in the direction of the engagement by receiving hydraulic pressure respectively. A cancel chamber is formed opposite to the first and second chambers through the clutch piston to cancel the centrifugal pressure generated in the first and second chambers. A selector valve selectively supplies hydraulic pressure to the first and second chambers according to a selected shift position of the automatic transmission to adapt to a different required engagement capacity in each shift position.

摘要： A shift control apparatus of an automatic transmission executes a transient control of an engagement pressure of a first speed selecting friction element when a first speed is selected after a higher speed is once selected during a change from a neutral range to a forward drive range. A band brake pressure for selecting the second speed is rapidly increased at a first moment. A forward clutch pressure for selecting the first speed is increased at a second moment delaying to the first moment by a predetermined period adjusted to a line pressure lowered period. The forward clutch pressure is pre-charged during a period between the first and second moments, then being hold for a preset time period at a return spring corresponding pressure adjusted by a leaning control, and being increased by a slope adjusted by the leaning control for a predetermined period to establish the second speed by the engagement of the forward clutch. Then, the band brake pressure is rapidly decreased and further decreased by a slope to disengage the band brake in order to establish the first speed.
