Abstract
(EN) An articulated bogie with an embedded vibration and noise reduction apparatus. The articulated bogie comprises a wheel set assembly (1), a side frame assembly (2), a swing bolster assembly (4), an integrated brake apparatus (5), an elastic side bearing assembly (7) and a central suspension and vibration reduction apparatus (8). The central suspension and vibration reduction apparatus (8) comprises tapered wedges (13), vibration reduction springs (14) mounted on the tapered wedges (13), inner circular springs (17) and outer circular springs (18), with the inner circular springs (17) being sleeved in the outer circular springs (18). The articulated bogie is characterized in that spring trays (16) are arranged at the upper ends of the inner circular springs (17), and stabilizing springs (15) are arranged in the spring trays (16) to form an embedded vibration reduction apparatus. According to the articulated bogie, the degrees of freedom of translation of the inner circular springs in the vertical direction are constrained, thereby eliminating noise pollution caused by the vibration of parts themselves and collisions between the parts and other adjacent parts.
(FR) La présente invention concerne un bogie articulé doté d'un appareil intégré de réduction des vibrations et du bruit. Le bogie articulé comprend un ensemble train de roues (1), un ensemble cadre latéral (2), un ensemble traverse oscillante (4), un appareil de freinage intégré (5), un ensemble palier latéral élastique (7) et une suspension centrale et un appareil de réduction des vibrations (8). La suspension centrale et l'appareil de réduction des vibrations (8) comprennent des coins coniques (13), des ressorts de réduction de vibrations (14) montés sur les coins coniques (13), des ressorts circulaires internes (17) et des ressorts circulaires externes (18), les ressorts circulaires internes (17) étant emmanchés dans les ressorts circulaires externes (18). Le bogie articulé est caractérisé en ce que des plateaux à ressort (16) sont agencés au niveau des extrémités supérieures des ressorts circulaires internes (17) et que des ressorts de stabilisation (15) sont agencés dans les plateaux à ressort (16) pour former un appareil intégré de réduction des vibrations. Selon le bogie articulé, les degrés de liberté de translation des ressorts circulaires internes dans la direction verticale sont limités, ce qui permet d'éliminer la pollution du bruit provoquée par la vibration des pièces elles-mêmes et des collisions entre les pièces et d'autres pièces adjacentes.
(ZH) 一种带有嵌入式减振降噪装置的铰接转向架,包括轮对组成(1)、侧架组成(2)、摇枕组成(4)、集成制动装置(5)、弹性旁承总成(7)以及中央悬挂及减振装置(8);中央悬挂及减振装置(8)包括斜楔(13)和安装于斜楔(13)上的减振弹簧(14)以及内圆弹簧(17)和外圆弹簧(18),内圆弹簧(17)套装于外圆弹簧(18)中,其特征是在内圆弹簧(17)上端置入弹簧托盘(16),弹簧托盘(16)内置入稳定弹簧(15),形成嵌入式减振装置,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。
