| description | A hydrodynamic reversing transmission for earth moving vehicles, forklift trucks or locomotives wherein the degree of filling of each torque converter of the forward drive train is controlled simultaneously with the degree of filling of the corresponding torque converter in the reverse drive train by a reversing valve. The reversing valve has a first operative position in which the filling and draining connections of one converter are respectively connected to the pump and sealed while the filling and draining connections of the other converter are connected to the sump to allow for complete draining of the other converter, a second operative position in which the filling and draining connections of the one converter are connected to the sump for complete draining of the one converter and the filling and draining connections of the other converter are respectively connected to the pump and sealed, and several intermediate positions in each of which the filling connections of both converters are connected with the pump and the draining connections of both converters communicate with the sump. This insures that the converter which is selected to transmit torque to the output shaft of the transmission is partially filled during adjustment of the reversing valve to the corresponding operative position. |
