Multi-axis cascaded electromechanical coupling structure for dual-rotor motors and hybrid electric vehicles

Abstract

The invention discloses a double-rotor motor and a multi-axis cascaded electromechanical coupling structure for a hybrid electric vehicle, wherein the double-rotor motor includes a stator, an inner rotor coaxially rotated and installed in the stator, and an inner rotor arranged between the stator and the stator in a manner of revolution and rotation. The outer rotor between the radial direction of the inner rotor; the permanent magnets of the outer ring of the outer rotor and the permanent magnets of the inner ring of the outer rotor are fixedly arranged on the outer rotor; One end of the rotor is fixedly provided with an outer rotor power output gear located outside the stator; by cascading the double rotor motors into a single motor and connecting it to the planetary row with multi-shafts, it is not only the integration of two motors, but fully functions as one The parallel system is ingeniously incorporated into the whole mechanism, and has the functions of electricity and mechanism at the same time, making it an integral part of the whole mechanism, and adding many sub-working modes to the main working mode of the mechanism, thus improving the mechanism reuse rate and power density.

Description

technical field [0001] The invention relates to the field, in particular to a double-rotor motor and a multi-axis cascaded electromechanical coupling structure for a hybrid electric vehicle. Background technique [0002] As a product that replaces traditional internal combustion engine vehicles, hybrid electric vehicles have attracted wide attention. Foreign companies such as Toyota (Toyota), Nissan (Nissan), GM (General Purpose), and Ford (Ford) have launched very mature hybrid electric vehicle products. , while hybrid drivetrains like Toyota's THS, Ford's FHS, and GM's AHS are widely used. Although domestic research on hybrid power transmission system has been more in recent years, due to the limitation of foreign patents, there are few mature products, which has also led to the slow development of hybrid electric vehicles in my country; and in the existing technology, the electromechanical coupling scheme The dual-rotor motor only decouples the speed, and decouples the to...

Although domestic research on hybrid power transmission system has been more in recent years, due to the restriction of foreign patents, there are few mature products, which has also led to the slow development of hybrid electric vehicles in my country; and in the existing technology, the electromechanical coupling scheme The dual-rotor motor only decouples the speed, and decouples the torque through another motor. Although its combination with the clutch provides more working modes, it also causes the mechanism to be too complicated, making the dual-rotor motor Features not fully exploited
