Abstract

The invention relates to a continuously variable transmission device (2) which includes: a guiding cover (4) rotating about a first axis (X4) a guided cover (6) rotating about a second axis (X6) a planet gear (20) provided with a first belt (205) in contact with an inner surface (S4) of the guiding cover and a second belt (207) in contact with an inner surface (S6) of the guided cover. Contact areas (Z4 Z6) between the belts and the inner surfaces of the covers are defined in a single first radial plane relative to the first axis. The planet gear (20) rotates about a third axis (X20) contained in the first radial plane and in which the angular orientation relative to the first axis (X4) defines the transmission ratio of the device. The planet gear pivots about a fourth axis (Y20) perpendicular to the first radial plane and nonintersecting with the first axis (X4). The planet gear (20) pivots about a fifth axis (Z20) parallel to the first radial plane and perpendicular to the third axis (X20).
