1. A continuously variable transmission belt (1) with a movable plate, comprising:

  • annular supporting body (2) and install horizontal component (3) on annular supporting body (2), characterized by;

    the transverse components (3) are continuously arranged and installed on the annular bearing body (2) and can transversely move left and right on the axis of the annular bearing body (2), so that tooth shapes with any shape and size can be formed on the surfaces of two sides of the transmission belt, and transmission teeth are arranged on the surface of the transmission wheel;

    the transmission wheel is a conical disk with a conical surface structure, the shape of the transmission teeth or tooth grooves on the surface of the transmission wheel is an approximately inverted trapezoid shape, the transmission teeth or tooth grooves gradually become wider from one side of the conical disk close to the circle center to the outer side of the conical disk, namely the transmission teeth or tooth grooves on the surface of the transmission wheel are different in width from one side of the circle center to different height positions on the outer side of the conical disk, the width of the transmission teeth or tooth grooves on the conical disk from one side of the circle center to different height positions on the outer side of the conical disk is slightly divided into thicknesses stacked by different numbers of sliding sheet combinations capable of transversely moving on the transmission belt, so that the transmission teeth or tooth grooves on the conical disk are suitable for the width change of the transmission teeth or tooth grooves on the conical disk from one side of the circle center to different height positions on the outer side of the conical disk, in the transmission process, the transmission teeth on the conical disk are in contact with the side surfaces of the transmission belt, and the transmission teeth on the conical disk from one side of the circle center to the The deformed teeth on the surfaces of the two sides of the transmission belt are meshed with the transmission teeth or the tooth grooves on the surface of the transmission wheel in the tooth grooves of the disk, and the width of the deformed teeth on the surfaces of the two sides of the transmission belt is adapted to the width change of the transmission teeth or the tooth grooves from one side of the circle center to the height position of the outer side of the conical disk, so that the tooth meshing transmission of the transmission belt and the transmission teeth or the tooth grooves of the transmission wheel is realized;

    the annular bearing body groove (4) is arranged on two outer sides of the transverse component (3), the annular bearing body (2) is arranged in the annular bearing body groove (4), the hoop ties (16) sleeved and tied on the annular bearing body (2) are arranged on the annular bearing body (2) at intervals along the annular direction, the inner sides of the fixing clamp feet (21) at two ends of the fixing clamp (7) are respectively fixedly connected with the outer sides of the two hoop ties (16) in the left and right corresponding annular bearing body grooves (4) on the transverse component (3), and the lower ends of the hoop ties (16) and the fixing clamp feet (21) are embedded in the fixing clamp sliding grooves (17) to prevent the transverse component (3) from longitudinally deflecting in the movement process.
