Description

V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a hybrid system that refers to a combination of an electric motor and an internal combustion power transmission system. [System configuration] [Previous technology] An electric locomotive transmission system, especially an engine The locomotive with power source is available in parallel hybrid power system. The hybrid power transmission system is a type that uses the internal combustion engine and electric power as the power source. According to its driving method, it can be divided into series, parallel, and some composite types that combine series and parallel characteristics. The main lies in the power configuration and Design of control strategies. Series hybrid power transmission = The system uses an electric motor to drive the vehicle, while the internal combustion engine is only used to generate electricity to supplement the battery power, and the parallel hybrid power transmission system drives the vehicle with both the internal combustion engine and the electric motor, for both purposes To improve the fuel economy and exhaust pollution of traditional internal combustion engine vehicles. The parallel hybrid power system has far more diversity and change space in terms of power configuration and control strategy than the serial type. This type of power system has the following characteristics: (i) the battery has a low battery capacity, and (2) the internal combustion engine engine can charge the battery. To maintain high residual power, (3) the internal combustion engine engine stalls at idle speed, (4) electric motor as the main driving source at low speed, (5) internal combustion engine engine as the main driving source at high speed, and the motor / generator depends on the drive Needed to regulate engine torque output. The biggest advantage of this power system is that it can relatively reduce the dependence on the battery capacity and minimize the negative impact of the low energy density of the battery. The conventional locomotive transmission system is divided into two categories: stepped transmissions that change gear to gear ratio and stepless transmissions with V-belt transmission. The gear type transmission has higher transmission efficiency, while the mechanical belt transmission has 200528336. V. Description of the invention (2) The simplest structure and good maneuverability, etc. The transmission efficiency is low. In the application of this system, the battery load is relatively increased. Cooperate with the clutch and brake design. The conventional locomotive hybrid powertrain transmission device is the main body. The transmission system hybrid electric vehicle uses an electric power to the two-degree-of-freedom planetary gear set, and jogs at more than a predetermined speed. 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 gear and surface efficiency area for modification. However, due to the complexity of the engine and power generation link, its controller's separation of the motor from the generator is less applicable. In the invention, the drive is provided at the starting point, and the transmission system provides a first-speed transmission, which is simple to control and low in transmission. At medium and high speeds, the engine with gear sets forms a turn-in-turn mode, and a second gear transmission with a reduction ratio improves the fuel economy of the engine. In addition, it also serves as a generator, but it does not distinguish one advantage, but it starts at low speed. Therefore, the present invention adopts 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, internal combustion engine and 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 battery assembly is used in a low-speed mode for a locomotive with limited space, 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 driven. The planet has a single degree of freedom, reactive power return, simple control and high transmission efficiency. However, the present invention uses a single electric motor and an electric motor to reduce
