<p>A transmission ratio variator establishes transmission between a drive shaft and a driven shaft between two orbital systems comprising gear wheels which move concentrically to their respective shafts and where the radii of each orbit are simultaneously variable. The gear wheels are mounted on shafts which are radially displaced in notches made in peripheric wings of sleeves joined to the control elements of the orbits. Each of the shafts of the gear wheels has a truncated thickening contained in a housing provided in each gear wheel. The shafts are axially displaced while blocked in and unblocked from the wheels depending on the direction of the displacement thereof which is controlled by a disc emerging from a ring which is displaced along the sleeve controlled by a double fork whose movement is controlled at will and is produced by conventional means.</p> |
