摘要： PROBLEM TO BE SOLVED: To reduce high frequency noise generated when a rocker pin and a pulley are kept into contact with each other by reducing high frequency vibration of the rocker pin mounted on a metallic belt of a belt type continuously variable transmission.
SOLUTION: In this belt type continuously variable transmission 1, a desired change gear ratio can be achieved by changing a pulley width of a driving pulley 5 and a driven pulley 8, and changing effective diameters of the driving pulley 5 and the driven pulley 8. The metallic belt 7 is a chain type metallic belt, and comprises a guide rail 50 receiving at least a part of the metallic belt 7, and a rail holding part 65 holding the guide rail 50 displaceably corresponding to the change of a passing locus of the metallic belt 7 corresponding to the change of the change gear ratio. The guide rail 50 is provided with a magnetic field generator 60 for generating the magnetic field in a receiving part 51 for the metallic belt 7, of the guide rail 50.

摘要： PROBLEM TO BE SOLVED: To provide a continuously variable transmission capable of avoiding resonance between a meshed frequency and a belted portion resonant frequency and preventing worsening of noises and a vibration level.
SOLUTION: A control unit of the continuously-variable transmission CVT is provided so as to change a gear ratio at continuously variable steps by changing a pulley-width variable drive pulley 11, a pulley-width variable driven pulley 16, a belt 15 wound up between the drive pulley 11 and the driven pulley 16, and a pulley width of both pulleys 11 and 16. The control unit comprises a meshed frequency calculating means S3 for calculating a meshed frequency F
a of the pulley 15 to the pulleys, a belted portion resonant frequency calculating means S4 for calculating a belted portion resonant frequency F
i of the belt 15, a resonance calculating means S5 for calculating a resonance determining value d of both frequencies from both frequencies F
a and F
i , and a resonance avoiding means S7 for changing the number of rotation and an operating state of the pulley in response to the resonance determining value d. For example, the gear ratio can be changed when idling an engine in a geared state.

摘要： PROBLEM TO BE SOLVED: To suppress the noise generated when a metal belt contacts a pulley by reducing the vibration of the metal belt in a belt stepless speed change gear.
SOLUTION: The belt-type stepless speed change gear is provided with a drive pulley 5 capable of changing the pulley width, a driven pulley 8 capable of changing the pulley width, and a metal belt 7 wounded between the drive pulley 5 and the driven pulley 8. The belt-type stepless speed change gear is formed to obtain the desired change ratio by changing the pitch diameters of the drive pulley 5 and the driven pulley 8 with changing the pulley widths of the drive pulley 5 and the driven pulley 8. A magnetic generator 50 generating a magnetic force in the perpendicular direction to the running direction of the metal belt 7 is provided around the crossing position of a passage trajectory at the minimum change gear ratio of the metal belt 7 and a passage trajectory at the maximum change gear ratio of the metal belt 7.
