Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a hybrid electric locomotive, which refers to a locomotive that combines an electric motor and an internal combustion engine as a driving system, especially a power transmission system. Hybrid [Prior Technology] & Power System. The hybrid power transmission system is based on internal combustion as the driving force. According to its driving method, it can be divided into series / ,, == up, and: a combination of some combination of series and parallel characteristics. The second is: Design of power allocation and control strategy. The tandem transmission system uses an electric motor to drive the straight rainbow, while Secret takes the knife to drive the system. The Emperor ’s Motor Vehicle Internal Combustion Engine is only used to generate power for aviation, and it is a parallel hybrid power transmission system. Both the internal combustion engine and the electric motor are used to drive the vehicle, and the purpose can be used to improve the fuel economy and exhaust pollution of the traditional internal combustion engine vehicle. The parallel hybrid power system has far more diversity in the power allocation method and control strategy than the series type. This type of power system has the following characteristics: (1), the avionics valley is low '(2) the internal combustion engine can be returned The charging bottle keeps it ^ = residual power, (3) the internal combustion engine engine stops at idle, (4) low speed # = electric motor is the main driving source, (5) at high speed, the internal combustion engine guides the engine to drive the source, motor / generator Depending on the drive needs to be adjusted ^, torque output. The greatest advantage of this type of power system is that it can be relatively minimized: the dependence of the amount of the bottle 2 'reduces the negative impact of the low energy density of the battery, and the two types of stepless transmissions with v-belt drive. Gear-type transmissions have the efficiency of old time, while mechanical belt-drive transmissions have the

In the application of this system, the battery load is relatively increased. With the design of the clutch and brake, the conventional locomotive hybrid powertrain transmission device is the main body.

Part of the engine The output power of the electric vehicle is charged or driven by the electric horse generator to operate through the two-degree-of-freedom planetary tooth load and the southern efficiency region for modification. However, due to the complexity of the engine-generator connection, its controllers are relatively inapplicable. The present invention provides a first-speed transmission at the start-up drive 'transmission system with simple control and low transmission. At medium and high speeds, the engine belt gear set forms an input light-on mode, and a second gear transmission with a reduction ratio improves engine fuel economy. In addition, it is a generator instead of distinguishing an advantage, but it uses a battery as a power transmission system at the start and low speed. Therefore, the present invention uses a planetary gear set to improve the transmission efficiency of the transmission system. The mechanical efficiency of mechanical rubber V-belts is low. The conventional parallel motor, the internal combustion engine and the generator are connected, so that the internal combustion engine and the electric motor can be driven together by the electric motor to drive the generator to generate electricity. The operating speed range of the engine can be achieved by the wheel set. The control to make it in full negative fuel economy and reduce the exhaust pollution machine is to make the manufacturing cost higher through the two-degree-of-freedom planetary gear set. In addition, when the electric component is used in a space-constrained locomotive and in the low-speed mode, the locomotive has a high degree of dynamic efficiency with a single degree of freedom of starting horses and a large reduction ratio. Therefore, the battery capacity needs to be activated, and the transmission system is simple in two groups. The planet has a single degree of freedom, reactive power return, 'simple control and high transmission efficiency.' The present invention uses a single electric motor and one electric motor, which can reduce
