城市轨道车辆及其轮盘制动转向架
摘要：
本发明公开了一种城市轨道车辆用轮盘制动转向架，包括至少两组轮对(1)，各组轮对(1)支撑有构架(2)，构架(2)两侧梁的中部支撑有空气弹簧(7)，轨道车辆的车厢体便支撑于该空气弹簧(7)上；任一组轮对(1)均包括一个轮轴(11)，该轮轴(11)的两端分别设有一个车轮(12)；所述转向架还包括踏面清扫装置，该踏面清扫装置安装于构架(2)上，用于对车轮(12)的踏面进行清扫。该转向架的结构设计能够易于对车轮的踏面进行清扫，使得车轮踏面保持清洁，从而一方面能够提高车轮与轮轨之间粘着利用率，另一方面能够避免车轮踏面和轮轨表面受到损坏。此外，还公开了一种包括上述转向架的城市轨道车辆。
摘要（英）：

The invention discloses a wheel-disc braked bogie for an urban rail vehicle, which comprises at least two wheel sets (1) and tread cleaning devices. A framework (2) is supported by each wheel set (1), an air spring (7) is supported between two side beams of each framework (2), a carriage of the rail vehicle is supported on the air springs (7), one optional wheel set (1) comprises an axle (11), wheels (12) are arranged at two ends of the axle (11) respectively, and the tread cleaning devices mounted on the frameworks (2) are used for cleaning treads of the wheels (12). The bogie in the structural design can facilitate cleaning of the treads of the wheels so that the treads of the wheels are kept clean, and further adhesion use ratio among the wheels and wheel rails can be increased, and damage of the treads of the wheels and the surfaces of the wheel rails can be avoided. Besides, the invention further discloses the urban rail vehicle comprising the bogie.
