Abstract

This invention deals with a speed variator used to modify the rotative motion ratio, to revers the sense of rotation on engines of vehicles or machines. The speed variator, according to the invention is made of an differential gear (1) and of a regulating system, which comprises a hydraulic or pneumatic pump(2) which backwaters the working fluid through a distributor( 3) and two throttles (4) to two hydraulic engines (5), the two throttles being interconnected, so that, the sum of the flows equals the flow of the fluid, backwatered by the pump; and the hydraulic engines (5), having their speed variation adjustable through the throttles (4), drive the differential gear (1) whose exit speed variation is adjustable by use of the throttles (4); in case the exit axle shaft's speed variation is null, by driving the distributor (3), the sense of rotation on the two hydraulic engines (5) may be reversed.
