The invention discloses an elastic wheel for a railway vehicle and a wheel set thereof, the wheel comprises a wheel core, a wheel rim, a gland, a rubber part and a bolt, the gland is mounted on the side surface of the wheel core through the bolt, the rubber part is a rubber ring, and the rubber ring is mounted in a groove cavity formed among the wheel core, the gland and the wheel rim; two symmetrical inclined groove cavities are formed among the wheel core, the gland and the wheel rim, the number of the rubber rings is two, and each rubber ring is arranged in the corresponding inclined groove cavity. The included angle between the long side of the cross section of the rubber part and the transfer axis of the elastic wheel is 12-18 degrees; the compression amount of the rubber part in the thickness direction is 1.1 mm-2. 5mm, and the compression ratio in the thickness direction is 4.5%-15%. The vibration and noise reduction effect is good, the structure is stable, and installation is convenient; compared with a common wheel set with an external bearing in the same specification, the vibration and noise reduction wheel set with the built-in bearing has excellent vibration and noise reduction effects.
本发明公开了一种轨道车辆用弹性车轮及其轮对,其车轮包括轮芯、轮箍、压盖、橡胶件以及螺栓,所述压盖通过螺栓安装在轮芯的侧面上,所述橡胶件为橡胶圈,橡胶圈安装在轮芯、压盖以及轮箍之间形成槽腔内;所述轮芯、压盖以及轮箍之间形成两个对称的斜槽腔,橡胶圈为两个,每个橡胶圈设在对应的斜槽腔内;橡胶件横截面的长边与弹性车轮中转轴线夹角为12°~18°;橡胶件厚度方向上的压缩量为1.1mm~2.5mm,厚度方向上的压缩率为4.5%~15%。其具有较好减振降噪效果,结构稳定,便于安装;轴承内置式减振降噪轮对,相较同规格轴承外置式普通轮对,具有较为优异的减振和降噪效果。
