摘要： Described is a method of controlling a power distribution hydromechanical branched transmission consisting of an adjustable hydrostatic unit (4), an integrating planetary gear (10) with at least two outputs (26, 27) and, connected to the integrating planetary gear, a range-changing gear (11) designed as a double planetary gear. The two outputs (26, 27) are connected to the range-changing gear (11) by a first clutch (K1) or a second clutch (K2), and one element of the range-changing gear (11) is controlled by a third clutch (KV). Additional clutches (K3, K4) are fitted for the other ranges. In conditions in which the gear-change position is uncertain, the first clutch (K1) or the second clutch (K2), depending on the instantaneous speed of the vehicle, is synchronized and engaged by adjusting the hydrostatic unit (4), and then either one of the other clutches (K3, K4) or the third clutch (KV) is synchronized and engaged.

摘要： The invention relates to a process for range switching of a hydrostatic and mechanical torque division gearing. The command is first given to close the coupling for the next range, the load is subsequently transferred to said coupling and the command to open the coupling is given for the old range (Vx) if a characteristic rotational speed value of the summation planetary gear (10), for example the rotational speed of the planetary carrier (25), remains constant during load transfer. Sensors for the coupling are consequently not required and more rapid range switching is achieved.

摘要： A drive unit consists of an internal combustion engine (1) and a continuously variable branching transmission comprising a steplessly variable hydrostatic motor-pump unit (4) and a summarizing gearbox (10) with connected sector gears (12, 13) for successive transmission sectors. In order to permit the operation of said drive unit even at operating points in an interval containing the change-points, the hydrostatic unit (4) is first continuously controlled as far as the changing point at a constant revolution speed of the engine, whereupon the clutch allocated to the next sector is closed and the desired speed is set and maintained by changing the engine revolution speed.
