The invention discloses an elastic wheel of a railway vehicle, which is characterized in that a first rubber outer ring, a first rigid plate and a first rubber inner ring are sequentially arranged between a wheel rim and a wheel core, a second rubber outer ring, a second rigid plate and a second rubber inner ring are sequentially arranged between the wheel rim and a compression ring, and the compression ring is connected with the wheel core through a fastener. The rubber outer ring, the rubber inner ring and the rigidity plate are matched through the concave-convex lotus edge structures, and the rubber outer ring and the rubber inner ring are prevented from rotating in a staggered mode in the tangential direction. Meanwhile, the rigidity plate made of metal is clamped between the rubber outer ring and the rubber inner ring, so that the overall circumferential tangential shear strength of the rubber outer ring and the rubber inner ring is greatly improved, large displacement dislocation caused by elastic deformation of rubber is avoided, and the problem that the elastic wheel is slow is solved. Meanwhile, the corrugated concave-convex structure is arranged on the rubber ring, and compared with the mode that a groove is formed in a metal piece, the machining procedures are greatly reduced, and the machining difficulty is lowered.
本发明公开了一种轨道车辆弹性车轮,其中轮箍和轮芯之间依次设有第一橡胶外环、第一刚度板和第一橡胶内环,轮箍和压环之间依次设有第二橡胶外环、第二刚度板和第二橡胶内环,压环通过紧固件与轮芯连接。本发明橡胶外环、橡胶内环与刚度板通过凹凸的荷花边结构进行配合,阻止了橡胶外环与橡胶内环之间沿切向错位转动。同时,夹于橡胶外环与橡胶内环中间的金属材质的刚度板,极大的提高了橡胶外环与橡胶内环整体的圆周切向抗剪切强度,避免因橡胶弹性变形导致的大位移错位,解决了弹性车轮的迟缓问题。同时,本发明将将荷叶边形的凹凸结构设置在橡胶环上,相比在金属件上设置凹槽,极大的减少了加工工序,降低了加工难度。
