摘要 PCT No. PCT/EP97/01429 Sec. 371 Date Aug. 10, 1998 Sec. 102(e) Date Aug. 10, 1998 PCT Filed Mar. 21, 1997 PCT Pub. No. WO97/37157 PCT Pub. Date Oct. 9, 1997A gear control for reduces the thermal stress on switching components (2, 3, 4, 5, 6) of a reversing gear (1) for machines having an input shaft (8) and an output shaft (15) and at least one directional switch for forward motion (2) and one for reverse motion (3) and a downstream load-switchable switching set (4) with several switching components (5, 6) allocated to a gear. Here the switching components (2, 3, 5, 6) can be electrically and/or hydraulically controlled by a regulating and control device (12) in such a way that, during a switching operation, in addition to one of the directional switching components (2, 3) corresponding to the switching operation, at least one other switching components (5, 6) of the downstream switching set (4) lying in the power flow and fully engaged at the start of a reversal is set to a slip state under frictional load. The frictional load is thus distributed between the directional switching components (2, 3) and the other slipping switching components (5, 6).
