摘要： Transmission mechanism has interlock mechanism (60) interlocking widening of circumcircle radius of one composite sprocket (5) and reduction of circumcircle radius of the other composite sprocket (5) during transmission ratio change. Interlock mechanism (60) is configured so that in a case where transmission ratio is changed toward uniform transmission ratio at which rotation speeds of two rotation shafts (1, 1) are the same, if actual chain length, which is real length of chain with respect to geometrical chain length that is length of ideal chain wound around two composite sprockets (5, 5) without excess and deficiency of chain length when widening and reduction are carried out by a same amount, is greater than predetermined length, reduction amount is set to be smaller than widening amount, while if the actual chain length is not greater than the predetermined length, the widening and reduction amounts are set to be the same.

摘要： There is provided an oil pressure control device for a belt-type continuously variable transmission which includes two pulleys and a belt, wherein each of the two pulleys has a movable sheave which moves by oil pressure supplied to a hydraulic chamber, wherein the oil pressure control device calculates a request torque according to a running state, wherein when calculating the oil pressure which is supplied to the hydraulic chamber of the movable sheave on the basis of the request torque, the oil pressure control device reduces the request torque if the request torque is greater by a predetermined value or more than an actual input torque which is inputted to the belt-type continuously variable transmission. Accordingly, it is possible to provide an oil pressure control device for a belt-type continuously variable transmission with which undesirable vibration can be avoided by means of stable speed-ratio control.

摘要： Provided is a control device of an automatic transmission, by which a supercharger can be prevented from becoming high in temperature and deteriorating in durability. An automatic transmission is connected to an engine (1) in which a supercharger (2) is mounted and has a manual mode to manually select a desired gear ratio from a plurality of fixed gear ratios. A control device includes a manual mode detection unit, a temperature judgment unit (31) and a gear ratio changeover unit (43) arranged such that, when the manual mode detection unit detects that the automatic transmission is in the manual mode and when the temperature judgment unit judges that the temperature of the supercharger is higher than or equal to a predetermined value, the gear ratio changeover unit changes the gear ratio of the automatic transmission to a higher gear ratio and thereby lowers the rotation speed of the engine (1).

摘要： In a hydraulic control circuit including a solenoid valve, whose change responsiveness in an actual pressure with respect to a change in an instructional pressure deteriorates when the instructional pressure enters a dead band region on a lower pressure side than a dead band threshold, for adjusting a hydraulic pressure supplied to a hydraulic device operated by the hydraulic pressure based on the instructional pressure, the instructional pressure is increased in a stepwise manner to a charge pressure higher than the dead band threshold, when the instructional pressure is set in the dead band region and the instructional pressure increases within the dead band region to such an extent that a speed ratio does not change. Then, a lower limit of the instructional pressure is set to the dead band threshold, and use of the dead band region is prohibited for a certain period of time.
