摘要： The invention relates to a hydrostatic and mechanical torque division gearing which comprises an adjustable hydrostatic unit (4), a summation planetary gear (10) with two input shafts (6, 8) and at least two output shafts, and a multi-step reduction gear (11) attached to the output shafts. The following process is being proposed to adjust very low speeds and stoppage in an exact and rapid manner: rotational speed signals are formed by sensors (50, 51) on the two input shafts (6, 8) of the summation planetary gear (10) and are compared with each other by counters (61, 62); the resulting actual pulse number difference is compared with a theoretical pulse number difference, and the output signal of a controller (66) responding to the result of said comparison adjusts the hydrostatic unit (4).

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.
