摘要： A hybrid multi-mode power take off system (PTO) installed on a vehicle includes an internal combustion engine, a first electric reversible electric machine, a second electric reversible electric machine and one epicyclical gear train connectable with the engine and the first and second reversible electrical machines using a number of clutches. An electronic control unit controls the closure/opening of clutches to implement different operating modes. The electronic control unit is configured to control the transfer of energy between the first and the second reversible electric machines when one reversible electric machine is operating as a motor and the other is operating as a generator.

摘要： An electric hybrid transmission architecture for a work vehicle includes a first and a second electric motor, each of which is electrically connected to a source of electric power. The first electric motor is configured to provide a torque to a first input shaft by converting electric power received from the source of electric power. The second electric motor is configured to provide a torque to a second input shaft by converting electric power received from the source of electric power. The electric hybrid transmission architecture also includes an output shaft which is mechanically connected to at least one of the first and second input shafts by means of controllable engaging means. The source of electric power is a generator carried by an internal combustion engine of the work vehicle.

摘要： Specialty tractor includes a diesel engine coupled with a powertrain including a clutch and a manual shift transmission having an output shaft that is designed to transmits power to the wheels of the tractor. An electric motor includes an output shaft connected through a power transmission to the output shaft of the manual shift transmission. The specialty tractor includes an electronic unit configured to perform at least a first operating mode and a second operating mode. In the first operating mode the clutch is opened and the manual transmission does not receive any torque from the diesel engine, and the electric motor transmits torque to the wheels the tractor. In the second operating mode the clutch is closed and the manual transmission receives torque from the diesel engine so that the engine-torque is transmitted to the wheels of the tractor that moves at a speed higher than the speed limit.
