Friction damper and electric tail gate mechanical supporting rod
The invention relates to the technical field of automobile parts, and discloses a friction damper and an electric tail gate mechanical supporting rod. The friction damper comprises a mounting rod, a limiting piece, an outer pressing ring, a compression spring and a friction sleeve; when the piston rod slides relative to the cylinder sleeve, pressure is continuously applied to the inner circumferential surface of the friction sleeve, so that the friction sleeve deforms, and the pressure generated by deformation of the friction sleeve continuously acts on the inner circumferential surface of the cylinder sleeve to form friction force so as to consume energy generated when the piston rod slides relative to the cylinder sleeve; according to the device, the preset damping is adjusted by adjusting the preset pressure of the compression spring and the friction coefficient of the friction sleeve, and due to the fact that the gap is formed in the peripheral face of the friction sleeve, when the friction sleeve is abraded, the pressure generated by the compression spring can cause deformation of the outer pressing ring, so that the abraded part of the friction sleeve is supplemented, and the damping effect is improved. And the stability of the damping effect is ensured.
本发明涉及汽车零部件技术领域，公开了一种摩擦阻尼器及电动尾门机械撑杆，摩擦阻尼器包括：安装杆、限位件、外压圈、压缩弹簧和摩擦套筒，该装置通过压缩弹簧的预设压力，使得径向截面为拱形的外压圈在受到压力后，会向摩擦套筒的内周面持续施压，进而导致摩擦套筒产生形变，由摩擦套筒形变产生的压力会持续作用至缸套的内周面，形成摩擦力，以消耗活塞杆相对于缸套滑动运动时产生的能量，该装置通过调节压缩弹簧的预设压力以及摩擦套筒的摩擦系数来调节预设阻尼的大小，并且由于在摩擦套筒的外周面开设有缝隙，使得摩擦套筒出现磨损时，压缩弹簧产生的压力会导致外压圈出现变形，以补充摩擦套筒被磨损的部分，保证了阻尼效果的稳定。
