Advances in automobile technology have led to the dynamic development of various types of active suspension systems to improve passenger riding comfort and maneuverability. This study improved the riding comfort of vehicle passengers by converting a conventional spring into a rotating C-shaped spring system that supports the load of the vehicle and varies its vertical stiffness. The C-shaped spring system rotates the spring in the multi-link suspension structure, utilizing the mechanical properties of the spring itself and the offset effect of the spring seat to vary the wheel rate. Using this effect, the riding comfort of an automobile can be improved to a certain level by altering the motion characteristics of the automobile body as it reacts to road bumps and irregularities. A C-shaped spring, an offset spring seat, and a rotating system were combined and installed on the rear suspension of an SUV. A field test of a vehicle driving over a speed bump was conducted to comparatively analyze the obtained data measurements, which verified the utility of the increased riding comfort when the vehicle was equipped with the proposed rotating C-shaped spring system.

汽车技术的进步导致了各种类型的主动悬架系统的动态发展，以提高乘客的乘坐舒适性和机动性。该研究通过将传统弹簧转换为旋转 C 形弹簧系统来支撑车辆负载并改变其垂直刚度，从而提高了车辆乘客的乘坐舒适性。C形弹簧系统在多连杆悬架结构中旋转弹簧，利用弹簧本身的机械特性和弹簧座的偏移作用来改变车轮速度。利用这种效果，通过改变车身在应对路面颠簸和不规则时的运动特性，可以将汽车的乘坐舒适性提高到一定水平。一个C形弹簧，一个偏置弹簧座，和旋转系统组合并安装在SUV的后悬架上。对在减速带上行驶的车辆进行了现场测试，以比较分析获得的数据测量结果，验证了当车辆配备所提出的旋转 C 形弹簧系统时增加乘坐舒适性的效用。
