Abstract

The invention relates to an output distributive 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 torque adjusting motor, a rotor and a permanent magnet 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. The sum of electromagnetic torque output to car wheel loads by the permanent magnet rotor and electromagnetic torque on a stator is equal to the torque input by the engine and the torque adjusting motor together. 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 output distribution type hybrid power system, which belongs to the technical field of automobile power devices. Background technique [0002] In 1997, Japan's Toyota Corporation launched the Prius, the world's first volume hybrid car. Because of its low energy consumption, low emission and good vehicle performance, Toyota Prius has attracted the attention and favor of many car manufacturers and consumers. As of the end of 2013, the cumulative sales volume of Toyota Prius has exceeded 3 million, and it is currently the most successful hybrid car in the world. [0003] Although Toyota Prius has undergone several generations of model changes, the basic composition of its internal hybrid system is the same. The hybrid power system of Toyota Prius is composed of engine, motor / generator 1, motor / generator 2, planetary gear mechanism, battery / supercapacitor and reducer, and its structure diagram is as follows figure 1 shown. Do...
