摘要： 现有汽车的四轮转向装置结构复杂成本高昂，不适合在整车轻便且平价的民众车型上使用。 文章提出一种基于飞锤离心装置控制的机械式汽车四轮转向系统，该系统利用飞锤感应车速，在 低速行驶时实现前后轮反向偏转以减小汽车转向半径，中速行驶转向时后轮不辅助转向，高速行 驶转向时前后轮同向偏转进而提高行驶稳定性，不同车速下后轮辅助转向幅度逐渐变化，无级调 节，使具有该系统的汽车在日益复杂的交通状况下更加灵活和稳定。通过对该系统进行仿真验证， 得到了预期的运算结果。

Abstract: The existing four wheel steering device is complex in structure and high in cost, so it is not suitable for use on a light and affordable public vehicle. This paper presents a mechanical four wheel steering system based on flyweight centrifugal device. The system uses flyweight to sense the speed of the vehicle, and realizes the reverse deflection of the front and rear wheels at low speed to reduce the steering radius of the vehicle. At medium speed, the rear wheels do not assist in steering, while at high speed, the front and rear wheels deflect in the same direction, so as to improve the driving stability. At different speeds, the rear wheel assists steering range changes gradually and is continuously variable, which makes the vehicle with this system more flexible and stable when used in increasingly complex traffic conditions. Through the simulation verification of the system, the expected calculation results are obtained.
