A traction rod node with high radial bearing capacity and high deflection capacity comprises a mandrel, a rubber body and an outer sleeve which are vulcanized into a whole, cavities are formed in the two radial ends of the rubber body, and rubber backstops protruding towards the outer sleeve are arranged in the cavities. The cavity forms two similar V shapes between the two circumferential sides of the rubber backstop and the rubber body, and a metal backstop protruding towards the direction of the outer sleeve is arranged at the position, located at the rubber backstop, of the mandrel. Under the bearing condition, the traction rod node can easily deflect in the space defined by the cavity, and the metal backstop can provide large radial rigidity, so that the traction rod node has small deflection rigidity while the large radial rigidity is guaranteed.
一种高径向承载、高偏转能力的牵引拉杆节点,包括硫化成整体的芯轴、橡胶体和外套,其中橡胶体在径向的两端处设有空穴,在空穴内设有朝外套方向凸出的橡胶止挡,使空穴在橡胶止挡沿周向两侧与橡胶本体之间形成两个类似于V型的形状,芯轴位于橡胶止挡处的部位设有朝外套方向凸出的金属止挡。在承载情况下,牵引拉杆节点能够很容易地在空穴所围成的空间内产生偏转,而金属止挡又能提供较大的径向刚度,从而使牵引拉杆节点在保证大径向刚度的同时具有小的偏转刚度。
