Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples.

[0022] The schematic diagram of the working principle of the present invention is as figure 1 As shown, the engine inputs the mechanical energy through the shaft to the dual-rotor motor, and the motor then inputs the energy to the magnetic continuously variable transmission. At the same time, the coil in the dual-rotor motor cuts the magnetic induction line to generate current, which is input to the coil winding of the magnetic continuously variable transmission through two transformations of the inverter so as to control the speed ratio of the transmission according to the different working conditions of the engine. At the same time Part of the electric energy can be stored in the battery as needed, and this part of energy can be input into the magnetic continuously variable transmission when needed, such as when the vehicle is accelerating. Wh...

Abstract

The invention provides a hybrid power system, which comprises a novel magnetic-force stepless transmission, a double-rotor motor and a battery, wherein an engine is connected with the double-rotor motor; the double-rotor motor inputs one part of mechanical energy from the engine into the novel magnetic-force stepless transmission; the other part of mechanical energy from the engine generates induced current in the motor; the induced current is input into a transmission coil by an inverter in a variable frequency mode so as to control the speed ratio of the magnetic-force stepless transmission; and meanwhile, the induced current can be stored into the battery in an electric energy form according to the requirement. According to the hybrid power system disclosed by the invention, the problem of bigger weight of a hybrid power automobile is solved while hybrid power driving is realized, meanwhile, the transmission efficiency is improved, and the manufacture cost is lowered.

Description

technical field [0001] This patent relates to a hybrid vehicle system, in particular, to a hybrid system based on a novel magnetic continuously variable transmission and a dual-rotor motor. Background technique [0002] Hybrid electric vehicles are a new generation of clean energy vehicles featuring low pollution and low fuel consumption. A set of hybrid power system with excellent performance plays a vital role in hybrid electric vehicles. However, the large size of most hybrid power systems now leads to heavy vehicle weight. At the same time, due to the multiple conversion of energy in the system and the low efficiency of the motor, the efficiency level of the entire system is not ideal. In addition, due to the use of hybrid drive, the cost of the car has also risen. In order to solve the above problems, the present invention proposes a hybrid power system based on a novel magnetic continuously variable transmission. Contents of the invention [0003] The object of th...
