摘要： The invention relates to a gear control system for a synchro-shuttle gear (1) or power shift gear (2), in particular in machines, comprising switching elements for a forward drive (SEV1, SEV2) or reverse drive (SER) and switching devices for actuating a shift valve (SV1) to select the direction of travel. A control valve (SV2) is provided between the switching elements for a forward drive and reverse drive and the shift valve capable of being actuated by the switching devices to select the direction of travel; said control valve (SV2) can be actuated via a further switching device. The control valve can be used as a neutral-position or idling valve in a synchro-shuttle gear or as a reversing valve for the switching elements for forward drive in a power shift gear.

摘要： An electro-hydraulic control device for power shift gearboxes, in particular in construction machinery, has switching elements (SE1, SE2, SE3) which can be actuated by a system pressure from an external pressurised medium source (1). Shift valves (SV1, SV2, SV3) are provided between the pressurised medium source (1) and the switching elements (SE1, SE2, SE3) and can each be actuated by a pilot pressure. Each of the switching elements (SE1, SE2, SE3) can be actuated in a defined switching state by at least two actuated shift valves (SV1, SV2, SV3) and at least one non-actuated shift valve.

摘要： A gear control system intended in particular for an electrically operated automatic transmission of layshaft design comprises the following elements: a hydraulic system with pressurised lines; a pump (5) for generating a system pressure; a first pressure reduction valve (6) for adjusting the system pressure; and switching elements (1, 2, 3, 4) at least one of which takes the form of a higher gear (1) for forward drive, another takes the form of a low gear (2) for forward drive, another takes the form of a switching element for reverse drive (3) and yet another takes the form of a clutch (4). The switching elements can be actuated by pressure via the pressure lines with pilot valves (10, 11, 12), and switching of one of the switching elements (1, 2, 3) or clutch (4) is defined by the switching position of the pilot valves (10, 11, 12) and of a multipath valve (16) connected upstream of the switching elements (1, 2, 3). The transmission control system has a reserve switching device which in the event of a voltage drop applies pressure to the multipath valve (16) to switch one of the switching elements (1, 2, 3) for forward or reverse drive, as well as a switch-back safety device which, when the reserve switching device is activated, prevents switching back from a higher gear (1) to a low gear (2), and an anti-transmission-blocking switching device which, if the clutch (4) and one of the switching elements (1, 2, 3) are actuated simultaneously, shuts off the pressure supply to the pilot valve (12) of the clutch (4) and to the pilot valve (11) of the switching element (2) and switching element (3).

摘要： The invention relates to a multispeed manual reverse gear unit, comprising an input shaft (1), countershafts (2, 3, 4, 5, 6, 7), and an output shaft (8). On the countershafts (2, 3, 4, 5, 6, 7), gears and/or idle gears are mounted, and said idle gears can be linked with the countershafts via clutches in a rotationally fixed manner for changing gears or the direction. The gear ratios are produced by spur pinion stages and at least one engaging and disengaging planetary stage (P).
