Abstract
In pedal vehicles with stepless transmission, a drive pulley unit comprising an automatic device for facilitating starting, in which the drive pulley comprises a pair of half pulleys (12, 13) mounted on a shaft (11), the first (12) being axially fixed and the second (13) being axially movable relative to the first, between the two half pulleys there being positioned a drive belt (14) engaging against walls of the two half pulleys (12, 13), which depending on their distance apart determine low gear or high gear, associated with the drive pulley unit there being provided a gear position regulator consisting of a counteracting element (18) associated with the movable second half pulley (13) via radially movable rolling bodies (24) inserted in respective housings (19, 37), wherein to the counteracting element (18) there are connected radially oscillable centrifugal masses (20) which are associated with an elastic element (31) and interact with the rolling bodies (24) at low speeds to cause the half pulleys (12, 13) to assume a position of maximum approach, determining high gear. <IMAGE>
