The embodiment of the invention relates to a rotating arm joint which comprises a mandrel, an elastic layer, an inner sleeve, an inerter and an outer sleeve. A blind hole is formed in the side wall of the mandrel; the elastic layer is arranged on the outer side of the side wall of the middle section of the mandrel, and a first through hole is formed in the elastic layer and communicated with the blind hole; the inner sleeve is arranged on the outer side of the elastic layer, and a second through hole is formed in the inner sleeve and communicated with the first through hole; the bottom of the inerter is fixed with the mandrel, and the top of the inerter is fixed with the inner sleeve; the inerter comprises a first spherical hinge arranged at the bottom, a second spherical hinge arranged at the top, a ball screw connected with the second spherical hinge and a flywheel; the outer sleeve is nested outside the inner sleeve; when the vehicle is subjected to impact load, impact acting force is transmitted to the bottom of the inerter through the mandrel and transmitted to the top of the inerter at the same time; under the buffering of the elastic layer, the force acting on the top and the force acting on the bottom of the inerter are different, the acting force is transmitted to the flywheel through the ball screw, the flywheel rotates, and the impact load borne by a vehicle is released.
本发明实施例涉及一种转臂节点包括芯轴、弹性层、内套、惯容器和外套;芯轴的侧壁上开设有盲孔;弹性层设置在芯轴的中间段侧壁的外侧,弹性层上开设有第一通孔,与盲孔相联通;内套设置在弹性层的外侧,内套上开设有第二通孔,与第一通孔相联通;惯容器的底部与芯轴相固定,顶部与内套相固定;惯容器包括设置在底部的第一球铰、顶部的第二球铰、与第二球铰连接的滚珠丝杆和飞轮;外套嵌套在内套外侧;当车辆受到冲击载荷时,冲击作用力通过芯轴传递至惯容器的底部,同时传递至惯容器的顶部;在弹性层的缓冲下使得作用在惯容器的顶部和底部的力不同,并通过滚珠丝杆将所受作用力传导至飞轮,飞轮发生旋转,释放车辆受到的冲击载荷。
