Abstract

The invention discloses a flywheel energy storage magnetic coupling transmission device which mainly comprises a housing, an inner case body, a flywheel rotor, a spindle and a magnetic coupling transmission mechanism, wherein a stator, a permanent magnet rotor and an adjustable magnet ring rotor of the magnetic coupling transmission mechanism are cylindrical; the adjustable magnet ring rotor is located between the stator and the permanent magnet rotor; a radial air gap exists between the adjustable magnet ring rotor and the stator; a radial air gap exists between the adjustable magnet ring rotor and the permanent magnet rotor; one end of an adjustable magnet ring rotor shaft is connected with the adjustable magnet ring rotor; and the other end of the adjustable magnet ring rotor shaft extends out of the housing. The device can recover braking energy of a vehicle; and compared with the traditional electric driven and mechanical flywheel energy storage systems, the device has the advantages of compact structure, small size, static sealing, small temperature rise in the case body, magnetic transmission, stepless speed change and the like.

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...
