New control and executive devices for multimotor electrohydraulic drives

The use of hydromechanical executive devices with mechanical differentials and two hydraulic motors is promising. Two-channel electrohydraulic power amplifiers of nozzle-gate type have been developed. A two-motor electrohydraulic drive with additional hydraulic distributors for compensation of the mutual loading has been proposed. Two designs of hydraulic executive mechanism have been developed. In one, the hollow output shaft serves as the spider.
