The invention relates to the field of braking energy recovery, and discloses a braking energy recovery method and system for improving the braking performance of a whole vehicle. The braking energy recovery system comprises a potential energy body, a lifter, a buffer linkage rod, a transmission gear set and a limiting device, the potential energy body is arranged above a chassis of the vehicle body, a space is reserved, the lifter is connected below the potential energy body, the lifter is connected with the chassis of the vehicle body through the buffer linkage rod, the transmission gear drives the buffer linkage rod to move, and the transmission gear set is used for transmitting mechanical energy of the potential energy body and the vehicle body; the limiting device is arranged above the potential energy body and used for fixing and releasing the potential energy body. Braking force generated when the vehicle brakes is recycled and converted into potential energy, the pressure of wheels on the ground is increased while the potential energy is converted, pitching of the vehicle is restrained, the braking performance is improved, and the braking distance is shortened; and meanwhile, when the vehicle is started, the driving force is improved by releasing the accumulated potential energy, the starting time is shortened, and the starting cost is reduced.
本发明涉及制动能量回收领域,公开了一种提高整车制动性能的制动能量回收方法及系统,包括势能体、升降器、缓冲连动杆、传动齿轮组、限位装置,势能体设置于汽车本体的底盘上方并留有空间,势能体下方连接升降器,升降器与汽车本体的底盘之间通过缓冲连动杆连接,传动齿轮带动缓冲连动杆运动,传动齿轮组用于传动势能体和汽车本体的机械能;限位装置设于势能体的上方,用于固定和释放势能体。本发明通过对汽车刹车时候产生的制动力进行回收,将制动力转换为势能,转化势能的同时车轮对地面的压力增加,抑制了车辆俯仰并提升了制动性能,减少了制动距离;同时,在汽车启动时候,通过释放累积的势能进而提高了驱动力,减小了启动时间和启动成本。
