摘要： A continuously variable transmission (4) comprises an endless torque transmission member (13) looped around a pair of pulleys (11, 12). At least one of the pulleys changes a winding radius of the endless torque transmission member (13) in accordance with an applied pulley thrust. A controller (22) estimates a stretch amount of the endless torque transmission member (13) based on an operating state of the continuously variable transmission (4), sets a slip limit thrust based on the stretch amount, and controls the pulley thrusts based on the slip limit thrust. In this manner, appropriate pulley thrust control in accordance with whether or not the endless torque transmission member (13) stretches is realized.

摘要： In a vehicular belt-driven continuously variable transmission, belt squeezing force is inhibited from becoming excessive and a safety factor, with respect to belt slip, of belt squeezing force applied to a transmission belt (48) is reduced to a value that is less than or equal to 1.5 by reducing a pressure receiving area (SOUT) of an output side hydraulic cylinder (46c). As a result, a centrifugal hydraulic pressure canceller chamber on a secondary pulley side (46) can be eliminated thus simplifying the structure of the vehicular belt-driven continuously variable transmission, while belt squeezing force can be appropriately controlled.

摘要： A method for diagnosing contact pressure security in a continuously variable transmission having conical disk pairs and a contacting endless belt. Contact pressure forces between the disks and the belt are modified at a given transmission ratio, at a defined input and/or output torque, and at a contact pressure having a defined zeta ratio value between the contact pressure force on the input disk set and on the output disk set. The input and/or output torque is held constant. The resulting change of transmission ratio is determined, and based upon the transmission ratio change the contact pressure security is assessed based upon the deviation between the existing pressure security and an optimum pressure security.
