The invented drive conversion equipment consists of series-connected individual modules (1a through 1d). It contains a sun-and-planet gearing (7) whose crown wheel (8) is coupled with an input shaft (2a) and whose sun gear (9) is blocked against rotation in opposite direction by a free wheel (16). A driver (13) is attached to an intermediate shaft (2ab), forming the input shaft of the first module (1a) of the invented drive conversion equipment. The crown wheel (8) and the driver (13) are coupled by means of a clutch (18a), that is compressed by a pressure exerted by centrifugal weights (29) in order to achieve direct drive. When the clutch (18a) is released by axial force (Pac), produced by helical teeth and acting against the centrifugal weights (29), the sun gear (9) is held captive by the free wheel (16) and the drive conversion equipment operates as a reducer. The sun-and-planet gearing (7) is arranged as an oil pump, whose delivery is connected to a transport passage (58) and the oil transport path further extends through a bundle of plates (19, 22). When the clutch (18a) is controlled b y the centrifugal weights (29), the oil transport path closes and engagement motion between teeth forming the oil pump tends to be eliminated. Therefore for achievement of direct drive by friction between plates (19, 22) only the teeth are held captive. Changes of gear speed ratios are thus more flexible and wear as well as clutch (18a) is reduced.
