Hydrostatic transmission, a method for controlling a hydrostatic transmission

摘要

Hydrostatic transmission, comprising– a housing (4)– a on the housing (4) relative to this, rotatably mounted around a rotational axis with a transmission output part (3), which is coupled to the cylinder block (b), each with a plurality of in each case arranged distributed in a circular pumps - cylinder bores (8) and motor - cylinder bores (18) and further comprising a radially inner annular oil conduit (52) and a radially outer annular oil conduit (53), between which a plurality of first the radial valve holes (57) with a respective pumps - opening (59) to one of the pumps - cylinder bores (8) and a plurality of second the radial valve holes (58), each with a motor - opening (60) to one of the motor - cylinder bores (18), whereby in each of the pumps - cylinder bores (8) a pumps - piston (9) is arranged so as to be displaceable and in each of said motor - cylinder bores (18) a motor - piston (19) is disposed in a displaceable manner, further comprising in each of the first valve holes (57) a first distribution valve (61) is arranged so as to be displaceable radially to the respective first valve hole (57) pumps associated with - opening (59) can be connected selectively to the inner..
