Hydrostatic transmission system for motor graders

摘要

The present invention relates to a system for hydrostatic transmission for grader comprising at least one hydraulic pump (10, 11) connected to at least one hydraulic motor (20, 21).The at least one hydraulic motor (20, 21) being connected to at least one speed reducer (30,31), the speed reducer (30, 31) being connected to at least one set of wheels (40,41) of the vehicle.Further, the invention relates to a system for hydrostatic transmission including a hydraulic pump and motor graders (10) connected to a hydraulic motor (20).The hydraulic motor (20) being connected to a differential (30), the difference being connected to a first and a second sets of wheels (40, 41) of the vehicle.The present invention allows to eliminate the need to use certain mechanical elements used conventionally in the transmission systems of the state of the art.Reducing the total weight of the system, its cost and complexity of manufacture and maintenance, easy installation and maintenance, and increasing their useful life.
