Description

technical field [0001] The invention belongs to an energy storage device, in particular to a flywheel energy storage magnetic force coupling transmission device, which is especially suitable for braking energy storage for vehicles. 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 ene...
