The invention relates to a multi-part rail wheel having a rim (8), having a wheel body (9) made of a light metal material, which wheel body has a hub opening (14) in which a contact surface (20, 21) is provided, on which an outer ring (17, 18) of a rolling bearing (15, 16) is supported in use or which contact surface is connected in use to an outer surface of a shaft or shaft end, the rail wheel also has at least one elastomer (10) arranged between the rim (8) and the wheel body (9), by means of which the rim (8) is elastically supported on the wheel body (9). In order to achieve good corrosion resistance, high resistance against mechanical actions, and to avoid current damage in the wheel bearing, the invention provides that at least the contact surfaces (20, 21) in the hub opening (14) of the wheel body (9) are covered with an electrically insulating oxide layer (OX) produced by electrochemical anodic oxidation. The invention also relates to a wheel set for a rail vehicle having such a rail wheel.

    本发明涉及一种多件式轨道车轮,其具有轮辋(8),具有由轻金属材料制成的轮体(9),该轮体具有轮毂开口(14),在该轮毂开口中设置有贴靠面(20、21),滚动轴承(15、16)的外圈(17、18)在使用中支撑在该贴靠面上,或者该贴靠面在使用中与轴或轴端的外表面连接,所述轨道车轮还具有至少一个布置在轮辋(8)和轮体(9)之间的弹性体(10),轮辋(8)通过该弹性体弹性地支撑在轮体(9)上。为了实现良好的耐腐蚀性、对抗机械作用的高抵抗能力、以及为了避免在车轮支承装置中的电流损伤,本发明规定,至少在轮体(9)的轮毂开口(14)中的贴靠面(20、21)覆盖有通过电化学阳极氧化产生的且电绝缘的氧化层(OX)。本发明还涉及一种用于轨道车辆的、具有这种轨道车轮的轮组。
