The invention relates to a wheelset bearing for a rail vehicle, and the wheelset bearing comprises a rolling bearing assembly (7) having three bearing rings (4, 8, 9), in particular two inner rings (4, 8) arranged for connection to a wheelset shaft (2) and one outer ring (9) arranged for connection to a housing (6). The rolling bearing assembly (7) is designed as a four-row angular contact ball bearing in an O-shaped arrangement in which two rows of rolling elements (16, 17) are arranged to contact the first inner ring (4) in order to absorb axial forces in a first direction and two rows of rolling elements (18, 19) are arranged to contact the second inner ring (8) in order to absorb forces in opposite axial directions. The invention also relates to a rail vehicle.
本发明涉及一种用于轨道车辆的轮对轴承,并且该轮对轴承包括具有三个轴承环(4,8,9)的滚动轴承组件(7),这些轴承环具体地为设置成用于连接至轮对轴(2)的两个内环(4,8)以及设置成用于连接至壳体(6)的一个外环(9)。滚动轴承组件(7)被设计为呈O型布置结构的四列角接触滚珠轴承,其中,两个滚动元件列(16,17)设置成接触第一内环(4)以便吸收第一方向上的轴向力,并且两个滚动元件列(18,19)设置成接触第二内环(8)以便吸收相反的轴向方向上的力。本发明还涉及一种轨道车辆。
