Abstract

Speed variator device fixed on the shaft of a two-speed electric motor having on the one hand two inner and outer pulleys connected by belts respectively to two pulleys of a driven shaft to form pairs of pulleys of different diameter ratios, and on the other hand a drag part supports between these inner and outer pulleys radially pivoting jaws, elastically requested towards the inner pulley by springs, device, characterized in that it comprises firstly radially pivoting jaws and their antagonist springs, the weight of the jaws and the tensile force of its opposing spring so that in an operation independent of the other organs of said device, and under the effect of centrifugal force, these jaws remain applied against the inner pulley, regardless of the speed of the motor; secondly for each of said jaws, a radially pivoting inertia block, its opposing springs and its two fingers, of which one is applied between the inner edge and the outer edge of the jaw, associated and is displaceable in space between these edges, the proper weight of the block and the tensile force of its opposing springs being determined so that, in operation in cooperation with the jaw associated but independent of the other organs of said device, and under the effect of the centrifugal force, the inertia block requests the jaw, against the inner pulley by the support of its finger on the inner edge thereof, for a speed of rotation of the motor lower than a predetermined value, and applies this jaw against the outer pulley by support of its finger on the outer edge of said jaw, for a speed of rotation of the motor superior to this predetermined value and, in third place, a blocking piece mº vil around the axis of rotation of the two pulleys and that has, for each block, an opening that receives the second finger of said block to prevent this block from reaching its radial end-limit towards the outside for a rotation of the motor in one direction given, and leave said block free in its radial displacement for a rotation of the motor in the reverse direction.
