| 摘要 |
The invention relates to a marine gear (10), in particular to a reversing gear, consisting of a hydraulic control assembly (12) comprising variable multi-plate clutches (14, 16) for forwards and reverse travel, in which the operating pressure required to engage the multi-plate clutches can be set using control means and consisting of an electronic control unit (18) for detecting and processing at least one operating parameter and for operating the control means. The control means comprise a proportional valve (20) and a pilot-operated pressure-control valve (24) for setting the desired operating pressure, which is located on the pressure-oil line (22) that leads to the multi-plate clutch (14, 16). The proportional valve (20) can be controlled by an electric control current (52) of the electronic control unit (18) and the pressure control valve (24) can be actuated by a control pressure that is generated by the proportional valve (20). The electronic control unit (18) is connected to a sensor for detecting the motor speed (26) and/or to a sensor for detecting the load signal (28) of a motor (30). |
