(EN) The utility model discloses a hinged bogie with an embedded vibration and noise reduction device, and relates to a railway freight car bogie, in particular to a hinged bogie. The hinged bogie comprises a wheel set assembly, a side frame assembly, a swing bolster assembly, an integrated braking device, an elastic side bearing assembly and a central suspension and vibration reduction device, whereinthe central suspension and vibration reduction device comprises a wedge, a vibration reduction spring, an inner circle spring and an outer circle spring, wherein the vibration reduction spring, the inner circle spring and the outer circle spring are installed on the wedge, and the inner circle spring is sleeved with the outer circle spring. The key technology is that a spring tray is arranged atthe upper end of an inner circle spring and a stabilizing spring is arranged in the spring tray, so that the embedded type damping device is formed. Compared with the prior art, the embedded damping device has the beneficial effects that through the effect of the embedded damping device, the translational degree of freedom of the inner circle spring in the vertical direction is restrained, noise pollution caused by vibration of parts and collision between the parts and adjacent parts is eliminated, and the environmental friendliness of a vehicle is further improved.
(ZH) 一种带有嵌入式减振降噪装置的铰接转向架，涉及一种铁道货车转向架，具体涉及一种铰接转向架。它包括轮对组成、侧架组成、摇枕组成、集成制动装置、弹性旁承总成以及中央悬挂及减振装置；中央悬挂及减振装置包括斜楔和安装于斜楔上的减振弹簧以及内圆弹簧和外圆弹簧，内圆弹簧套装于外圆弹簧中。其关键技术是在内圆弹簧上端置入弹簧托盘，弹簧托盘内置入稳定弹簧，形成嵌入式减振装置。本发明具有的有益效果是：通过嵌入式减振装置的作用，约束了内圆弹簧在垂向方向的平动自由度，消除了由于零部件自身的振动及与相邻零部件间的磕碰造成的噪音污染，进一步提高了车辆的环境友好度。
