<p>PCT No. PCT/AT97/00083 Sec. 371 Date Oct. 29, 1998 Sec. 102(e) Date Oct. 29, 1998 PCT Filed Apr. 29, 1997 PCT Pub. No. WO97/41371 PCT Pub. Date Nov. 6, 1997A hydrostatic/mechanical multiple path power transmission comprises an adjustable hydrostat unit (4), a summing planetary gearbox (10) with two input shafts (6, 8) and at least two output shafts, and a step gearbox (11) connected to the output shafts. In order to adjust low speeds and standstill precisely and rapidly, the following method is specified: rotational speed signals are formed by sensors (50, 51) on the two input shafts (6, 8) of the summing planetary gearbox (10), and are compared with each other by counters (61, 62); the actual pulse count difference formed in this way is compared with a desired pulse count difference, and a controller [sic] and the output signal of a controller (66) that responds to the result of this comparison effects adjustment of the hydrostat (4).</p> |
