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; and a sound insulation cover which is connected with the framework in a sealed mode, a containing space is defined between the sound insulation cover and the framework, and the brake is arranged in the containing space. According to the bogie, the acoustic hood is connected with the framework in the sealed mode, the brake is arranged in the containing space defined between the acoustic hood and the framework, and when the bogie is applied to the railway vehicle, air noise generated by the brake can be well isolated, so that noise in the vehicle and noise outside the vehicle are effectively reduced; and the influence of noise outside the vehicle on the surrounding environment can be avoided while the riding comfort of passengers in the vehicle is improved. Moreover, the sound insulation cover is small in size and compact in structure, the occupied space of the whole bogie can be reduced, and the material cost can be reduced.
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,所述隔声罩与所述构架之间限定出容纳空间,所述制动器设在所述容纳空间内。根据本发明的转向架,通过使隔声罩与构架密封连接且制动器设在隔声罩与构架之间限定出的容纳空间内,当转向架应用于轨道车辆时,可以很好地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,在提高车内乘客的乘车舒适性的同时,可以避免车外噪声对周边环境的影响。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,且可以降低用料成本。
