The invention discloses a 48V electromechanical coupling driving device of a flywheel integrated electric automobile and a using method of the 48V electromechanical coupling driving device, and belongs to the technical field of automobile engineering. The device comprises a box body which is of a hollow structure, and a 48V driving motor, a flywheel rotor, a 48V speed regulating motor and a poweroutput shaft are sequentially arranged in the box body from left to right; the 48V driving motor is in transmission connection with the flywheel rotor through a flywheel shaft; the flywheel rotor is connected with the 48V speed regulating motor through a planetary mechanism, a sun gear of the planetary mechanism is in transmission connection with the end part of the flywheel shaft, and a planet gear of the planetary mechanism is in transmission connection with the 48V speed regulating motor; one end of the power output shaft is in transmission connection with a planet carrier of the planet mechanism; and the other end stretches out of the box body. according to the invention, braking energy during vehicle braking is mainly recycled and reused in a kinetic energy form, so that a high-powerpeak value in the charging process of the power battery can be effectively avoided in the initial stage of braking, auxiliary power can be directly provided in the kinetic energy form in the startingand accelerating processes of the vehicle, and the service life of the power battery and mechanical braking parts is prolonged.

    本发明公开了一种飞轮集成式电动汽车48V机电耦合驱动装置及其使用方法,属于汽车工程技术领域。装置包括箱体,其为中空结构,其内从左到右依次布置有48V驱动电机、飞轮转子、48V调速电机和动力输出轴;48V驱动电机与飞轮转子通过飞轮轴传动连接;飞轮转子与48V调速电机通过行星机构连接,行星机构的太阳轮与飞轮轴端部传动连接,行星机构的行星轮与48V调速电机传动连接;动力输出轴一端与行星机构的行星架传动连接,另一端伸出箱体外。本发明使车辆制动时的制动能量主要以动能形式回收和再利用,既可在制动初期有效避免动力电池充电过程中的高功率峰值,又能在车辆起步和加速过程中直接以动能形式提供辅助功率,延长动力电池和机械制动部件的使用寿命。
