Claims

[Scope of utility model registration request]

Consisting of a fixed pulley piece and a movable pulley piece, the movable pulley piece is provided on the axial extension of the fixed pulley piece so as to be movable in the axial direction and rotational direction, and the movable pulley piece is provided on one side on the axial extension of the fixed pulley piece. A repulsive elastic coil spring is interposed between the spring retainer and the movable pulley piece, and both ends of the spring are engaged with protruding pins provided on the sides of the movable pulley piece and the spring retainer, respectively, when traveling. , one pulley is a speed change pulley configured so that a load generated by a belt suspended on the pulley generates a load in the direction of winding and unwinding of the spring, while the other pulley is a fixed V pulley, and is fixed to the speed change pulley. ■ In a belt transmission device in which a movable tension pulley is provided in the middle of the pulleys and ■ a belt is suspended between these two pulleys and the tension pulley, a part of the shaft of one side of the fixed pulley of the one speed change pulley and an integral member. One or more protrusions are provided on a part of one side of the movable pulley at partial pitches around the circumference, and a magnetic rotary pickup is disposed near the protrusions from outside the pulley in close opposition to the protrusions. The rotation of each pulley piece during rotation can be detected by a pulse signal, and the relative torsion amount of one side of the movable pulley with respect to one side of the fixed pulley can be determined by the phase difference between the pulse signals generated from the fixed pulley piece and the one side of the movable pulley. is detected, the signal is electrically processed, and based on the signal, external actuating power is actuated via an amplifier having a control function so that the relative torsion angle of the fixed pulley piece and the movable pulley piece is maintained at a predetermined set value. At the same time, the tension pulley is moved by the external operating power, and the movable pulley piece of the one speed change pulley is moved and adjusted in the axial direction in accordance with the movement, and the belt in the speed change pulley formed by both pulley pieces is moved. A belt-type torque control device characterized in that the winding is equipped with an electric control means for changing the effective diameter.
