  • Method for influencing the tension in a drive belt
    Patent number: 5683318
    Abstract: The invention relates to a method for influencing the tension in a drive belt in a continuously variable transmission. According to the invention, the tensions in the drive belt are determined as a function of the speed of the drive belt. For part, parts or the entire range of the possible input speeds of the transmission, the input speed of the transmission is then increased and/or reduced to a desired speed range for the drive belt with an essentially relatively lower tension in the drive belt. The power density, the efficiency and the control range of the transmission can be improved by application of this method.
