200528333 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention is a geared locomotive hybrid power transmission system, especially 1 3 refers to a machine that combines an electric motor and an internal combustion engine as the source of power. II = Power transmission system, system The configuration is a parallel hybrid power system. [Previous technology] A hybrid power transmission system is a type of engine that uses an internal combustion engine and an electric motor as the power source. According to its driving method, it can be divided into series, parallel, and some combination types that combine the characteristics of series and parallel. The main difference is the design of power allocation and control strategies. The series hybrid power transmission 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. The purpose is all available To improve the fuel economy and exhaust pollution of traditional internal combustion engine vehicles. The parallel hybrid power system is far more versatile and variable in terms of power configuration and control strategy than the series 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 be recharged. 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 conventional motors, internal combustion engines and generators can be used by the electric motors to generate electricity alone. The operating speed range of the engine can be controlled to make it more economical and reduce exhaust pollution. The two-degree-of-freedom planetary gear is composed of two partial deviations. In addition, the main purpose of electricity for space-constrained locomotives is to provide a visual output of the force required by the locomotive to drive or supplement the battery power, reduce the total weight and space requirements of the battery capacity of the car, and adjust the internal combustion engine.

The geared locomotive hybrid power transmission system described in Item 丨 of the patent application park, the electric motor can be connected to the planet carrier of the first planetary gear set, and the fixed part of the first planetary sick wheel set can be the planet. The sun gear of the gear set; the brake can be connected to the sun gear of the second planetary gear set; the ring gear of the first planetary gear set is connected to the ring gear of the second planetary gear set, and the shift clutch is located on the first planet Between the planet carrier of the gear set and the sun gear of the second planetary gear set; the neutral clutch is located between the internal combustion engine and the ring gear of the first planetary gear set. 6. The geared locomotive hybrid power transmission system described in item 丨 of the scope of the patent application, the electric motor can be connected to the planet carrier of the first planetary gear set, and the fixed part of the star gear set can be the planet. Gear set ring Page 21 200528333 VI. Patent application range wheel; the brake planetary gear set shift clutch gear set is too large the first planet 7. Rushen transmission system, frame, the first ring wheel; the planetary gear set should be shifted The first planet 8. Rushen transmission system of the clutch star gear set. The “star frame and the 9. Rushen transmission system” may be a one-way clutch, which may be connected between the sun gear and the first sun gear; The scope of the gear set is patented. The sun gear that can be connected to the planetary gear set of the electric motor is located between the first ring gear. The scope of the gear set is patented. The patent range is between the final drive output shaft. Clutch, electric sun gear of the second planetary gear set; the ring wheel of the first and the first planetary gear set is connected, the planet carrier of the planetary gear set and the second planet, and the neutral clutch is located between the internal combustion engine and the sun Between rounds. The hybrid power of the geared locomotive according to item 1 which can be connected to the planets of the first planetary gear set may be ring wheels of the second planetary gear set of the first planetary gear set; the first and second planets The sun gear of the gear set is connected. The planet carrier of a planetary gear set and the neutral clutch in the second row are located between the internal combustion engine and the sun gear. The geared locomotive hybrid power device according to item 1 is connected to the second planetary gear set. The geared locomotive hybrid power device according to item 1, the shift clutch, and the brake clutch or centrifugal clutch. Page 22
