Abstract
For the purpose of driving a body (8) that, in order to perform a tumbling and rotating movement, is suspended by means of pivot pins (9) on two fork-shaped gimbals (5, 7) which are each connected by means of a pivot bearing (4, 6) to the end of one of two parallel drive shafts (2, 3), each of the drive shafts (2, 3) is driven by a hydraulic motor (12, 13). The two hydraulic motors (12, 13) are connected to a common hydraulic pump (14) by means of a branched line (15, 16, 17). The volumetric displacement of the pump (14) is divided between the two hydraulic motors (12, 13) in such a manner that each of the hydraulic motors (12, 13) is supplied with an alternately interchanging increasing or decreasing partial volume in order that the two drive shafts (2, 3) rotate non-uniformly in the manner required for uniform movement of the body, the kinematics of the system consisting of the mutually connected shafts (2, 3), the fork shaped gimbals (5, 7) and the body (8) producing the correct distribution of the quantities of oil between the motors.
