The embodiment of the invention provides a damper with adjustable frequency and a steering wheel damping system, the damper comprises a sleeve and an elastic part molded on the peripheral side of the sleeve, the elastic part extends along the direction perpendicular to the axis of the sleeve to form an annular supporting part, a plurality of through grooves are formed in the annular supporting part, the damper is arranged in an opening of a mounting device, and the through grooves are communicated with the through grooves. The opening is provided with a wedge-shaped part with the hole diameter gradually reduced, in the process that the damper is installed towards the opening, the periphery of the annular supporting part is gradually extruded by the wedge-shaped part to generate plastic deformation, and frequency adjustment of the damper is achieved by adjusting the final installation position of the damper. A plurality of through grooves are formed in an elastic part, an opening with a wedge-shaped part of which the aperture is gradually reduced is formed in a mounting device for mounting the damper, and when the damper is mounted, the elastic part is extruded by the wedge-shaped part in the circumferential direction to generate plastic deformation, so that the frequency of the damper is changed; and the dampers with different frequencies are obtained by adjusting the final mounting positions of the dampers.

    本说明书实施例提供一种可调频率的阻尼器及方向盘阻尼系统,阻尼器包括套筒和模制在套筒外周侧的弹性部,弹性部沿垂直于套筒轴线的方向延伸形成环状支撑部,环状支撑部上开设有若干通槽,阻尼器设置于安装器件的开口中,开口具有孔径逐渐减小的楔型部,阻尼器在向开口的安装过程中,环状支撑部外周逐渐受到楔型部挤压而发生塑性变形,通过调整阻尼器的最终安装位置实现其频率调节。通过在弹性部上开设若干通槽,且在用于安装阻尼器的安装器件上开设具有孔径逐渐减小的楔型部的开口,当阻尼器进行安装时,弹性部周向受到楔型部挤压而发生塑性变形,从而使得阻尼器的频率发生改变,通过调整阻尼器的最终安装位置得到不同频率的阻尼器。
