采用回收装置把制动能量回收到车上的能量储备器内,可提供显著降低车辆燃油消耗的可能。一种通用的技术是制动时在混合电驱动马达内产生电能,用它为车上电化学电池充电。然而这种电池价格昂贵、笨重,而且一般它不能承受快速充电,这将影响到它的寿命和容量。为了解决这样的问题,推荐和研究一种机械能储存装置,可接受和输送能量的波动。该装置的比例物理模型由飞轮载体、行星齿轮传动和一制动器组成,并已建成和运转在实验室内。试验表明,所推荐的装置可以用来储存和提供飞轮和车辆间制动能量,以后用一空气阻力测功器模拟,论证了该装置的运行原理和它的计算模型。进一步介绍了全尺寸车辆结合机械能量储存装置的计算分析,结果表明,该装置在车辆中使用,和通常的车辆相比较,可导致车辆的排放和燃油消耗降低。
The use of recovery devices to recover the braking energy into the car’s energy reserve can provide a significant reduction in vehicle fuel consumption. A common technique is to generate electrical energy in a hybrid electric drive motor while braking, which is used to charge the on-board electrochemical cell. However, this kind of battery is expensive, cumbersome, and generally it can not withstand rapid charging, which will affect its life and capacity. In order to solve such a problem, it is recommended and researched a mechanical energy storage device that can accept and deliver energy fluctuations. The device’s proportional physical model consists of a flywheel carrier, a planetary gear and a brake, and has been built and operated in a laboratory. Experiments show that the proposed device can be used to store and provide braking energy between the flywheel and the vehicle. Afterwards, an air resistance dynamometer is used to simulate the operating principle of the device and its calculation model. The calculation and analysis of the full-size vehicle combined with the mechanical energy storage device are further introduced. The results show that the device is used in the vehicle and can reduce vehicle emissions and fuel consumption compared with the conventional vehicle.
