Abstract
A hydrodynamic reversing transmission with discrete first and second hydrodynamic starting torque converters in the forward and reverse drive trains and an additional torque converter which is installed in the forward drive train and is actuatable to transmit torque in the intermediate or higher speed range of the respective drive train has a clutch which is rendered operative simultaneously with the second torque converter to enhance the braking action while the vehicle which utilizes the transmission moves in the preferred forward direction. The clutch performs a dual function, namely, to assist the second torque converter in braking the vehicle, such as a dump truck, while the vehicle moves in the preferred direction, as well as to drive the output shaft of the transmission in the higher or highest speed range of the forward drive train. When the clutch assists in braking of the vehicle, it transmits torque from the wheels of the vehicle (i.e., from the output shaft of the transmission) to the input side of the transmission. The clutch may be installed in a discrete housing which is separably connected to the transmission case.
