Title
(EN) Bogie and railway vehicle with same
(ZH) 转向架和具有其的轨道车辆
Abstract
(EN) The invention discloses a bogie and a railway vehicle with the same. The bogie comprises a framework; a brake which is arranged on the framework; a sound insulation cover which is connected with the framework in a sealed mode, the sound insulation cover and the framework jointly define a containing space, and the brake is arranged in the containing space; and a transverse backstop which is arranged on the sound insulation cover, and the transverse backstop is located on the side, away from the center of the framework, of the sound insulation cover. According to the bogie, air noise generated by the brake can be effectively isolated, and therefore noise in a vehicle and noise outside the vehicle are effectively reduced. Moreover, the sound insulation cover is small in size and compact in structure, and the occupied space of the whole bogie can be reduced. In addition, the transverse backstop is arranged on the acoustic shield, so that the integration level of the bogie is better, and the structural compactness of the bogie can be further improved.
(ZH) 本发明公开了一种转向架和具有其的轨道车辆,所述转向架包括:构架;制动器,所述制动器设在所述构架上;隔声罩,所述隔声罩与所述构架密封连接,所述隔声罩和所述构架共同限定出容纳空间,所述制动器设在所述容纳空间内;横向止挡,所述横向止挡设在所述隔声罩上,且所述横向止挡位于所述隔声罩的远离所述构架的中心的一侧。根据本发明的转向架,可以有效隔绝制动器产生的空气噪声,从而有效降低车内噪声和车外噪声。而且,隔声罩的体积较小,结构紧凑,可以减小整个转向架的占用空间。另外,通过将横向止挡设在隔声罩上,使转向架的集成度更好,从而可以进一步提高转向架的结构紧凑性。
