The invention relates to a damping type automobile gravitational potential energy recovery device which is characterized in that potential energy generated by factors such as left-right inclination of an automobile body caused by up-and-down bumping and turning of the automobile body and forward inclination of the automobile body after speed reduction and braking under the condition of normal driving of the automobile is recycled and reused. The system is characterized by comprising a hydraulic potential energy conversion device (a double-acting hydraulic oil cylinder and a three-way reversing valve), an energy buffer device (a high-pressure buffer, a high-pressure oil way and a double-channel throttle valve), an energy conversion device (a high-speed hydraulic motor and a generator with a speed change device), a low-pressure oil way, a low-pressure reservoir and other main components. The method is suitable for plug-in hybrid power and new energy pure electric vehicles, and belongs to the field of new energy recovery technical equipment of electric vehicles.
本技术发明涉及的是一种减震式汽车重力势能回收装置,其特征是利用汽车在正常行驶的情况下,因车身上下颠簸起伏和变道转弯而引起的车身左右倾斜,以及减速刹车后的车身前倾等因素而产生的势能能量,进行回收再利用,其特征包括:液压势能转换装置(双作用液压油缸,三通换向阀),能量缓存装置(高压缓存器,高压油路,双通道节流阀),能量转换装置(高速液压马达及带变速装置发电机)以及低压油路和低压储存器等主要部件构成,优适应于插电式混合动力及新能源纯电动汽车,属于电动汽车新能源回收技术设备领域。
