Flywheel-motor magnetic coupling transmission hybrid power system

Abstract

The invention discloses a flywheel-motor magnetic coupling transmission hybrid power system. The system comprises a flywheel energy storage magnetic coupling transmission device, an electromagnetic clutch and a double-rotor motor; one end of an inner rotor shaft of the motor of the double-rotor motor is movably connected with the active part of the electromagnetic clutch through a bearing, and theother end of the inner rotor shaft of the motor is movably connected with a connecting body through a bearing; the permanent magnet inner rotor of the motor is connected with the inner rotor shaft ofthe motor; the motor stator is connected with the main box body; one end of the motor magnetic regulation outer rotor is movably connected with the motor main box body through a bearing, and the other end of the motor magnetic regulation outer rotor is fixedly connected with one end of the connecting body; the other end of the connecting body extends out of the cavity structure and is connected with an external load; a flywheel energy storage magnetic coupling transmission device, a magnetic coupling transmission mechanism and a double-rotor motor are cooperatively matched, so that normal uniform-speed running of an automobile, recovery of braking energy during braking and downhill running of the automobile and conversion of kinetic energy of a flywheel into kinetic energy during acceleration and uphill running of the automobile are achieved.

Description

technical field [0001] The invention relates to a hybrid power system including an energy storage device, in particular to a flywheel-motor magnetic coupling transmission hybrid power system. Background technique [0002] With the increasingly prominent energy crisis and environmental problems, the development of energy-saving and environment-friendly vehicles has become a future automobile industry. industry development trend. From the perspective of energy saving, the energy-saving effect of driving vehicles is mainly reflected in two aspects: one is that on hybrid electric vehicles (including some plug-in types), it is possible to control the internal combustion engine to always work in a high-efficiency area; A large amount of kinetic energy can be recovered in the process. Since the energy consumed by braking accounts for a large proportion of the energy consumed by driving, most electric vehicles are equipped with a braking energy recovery function. Flywheel energy ...
