Abstract

The invention relates to an input combined hybrid power system and belongs to the technical field of car power devices. The system aims at solving the problem of transmission consumption, gear vibration, noise and abrasions caused by the fact that planetary gear mechanisms used by Toyota Prius hybrid power systems are pure mechanical devices. According to the technical scheme, an output shaft of an engine is connected with a permanent magnetic rotor and a modulation ring rotor of a magnetic field modulation brushless bi-rotor engine, a main reducer and car wheels successively. Different working modes in the system are achieved through the switching of a brake and two clutches of a holding mechanism, and electromagnetic torque output by the modulation ring rotor is equal to the sum of engine input torque and stator electromagnetic torque. Decoupling of the engine rotation speed is achieved by the magnetic field modulation brushless bi-rotor engine, and decoupling of the engine torque is achieved through the torque adjusting motor, so that the engine rotation speed torque is independent of the load rotation speed torque.

Description

Technical field [0001] The invention relates to an input synthesis type hybrid power system and belongs to the technical field of automobile power devices. Background technique [0002] In 1997, Japan's Toyota introduced the Prius, the world's first mass hybrid car. Toyota Prius has received the attention and favor of many automakers and consumers because of its advantages of low energy consumption, low emissions and good vehicle performance. As of the end of 2013, the cumulative sales of Toyota Prius has exceeded 3 million, making it the most successful hybrid car in the world. [0003] Although Toyota Prius has undergone several generations of model changes, the basic structure of its internal hybrid system is the same. The hybrid power system of Toyota Prius is composed of engine, electric motor / generator 1, electric motor / generator 2, planetary gear mechanism, battery / super capacitor and reducer. Its structure diagram is as follows figure 1 Shown. The dotted line in the figu...
