    摘要: A 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).

    摘要: A control of a drive train for a wheel loader having one pressure-medium actuated brake and one transmission operated via a torque converter and at least one forward and/or reverse gear respectively actuated via a power shift clutch and one power take off wherein, when a predetermined value of the power delivered by the transmission to the power take off is exceeded, the pressure of the engaged power shift clutch for the forward or reverse gear is reduced to a residual level.

    摘要: A pressure-control device is used to affect the engaging behavior of powershift clutches in a powershift gear with a control valve cooperating with a damping device, as a pressure-control valve (2), by which the pressure cycle can be set on engaging the clutch concerned. The pressure in a chamber (C3), between a displacement piston (4) and a pressure-control piston (3), can be controlled via a first switching valve (11) switched by a magnetic valve (10). A chamber (C2) behind the displacement piston (4) can be exhausted, via a second switching valve (14) switched by the same magnetic valve (10), whereby the pressure-control piston (3) is held in its initial position to release the full valve aperture cross section from the pressure line (1) to the clutch line (7).
