Abstract
(EN)
A maglev vehicle and a suspension frame assembly thereof. The suspension frame assembly comprises multiple suspension frames (1) sequentially connected to each other. Each suspension frame (1) comprises two motor beams (11), four support arms (12), and four air springs (13). An air spring mounting seat (125) is disposed at a top portion of each support arm (12). The air spring mounting seats (125) are cavities having openings. The air springs (13) are accommodated in the respective cavities. The suspension frame assembly uses the cavity disposed on the support arm (12) as the air spring mounting seat (125), such that the air spring (13) is disposed in the support arm (12), thereby eliminating the need for an air spring dust cover, a transverse pull rod, and an air spring arm support beam, reducing the height of a top surface of the air spring (13), and solving the issue in which the suspension frame (1) is heavy, has a high center of gravity, and is required to be provided with an air spring dust cover.
(FR)
L'invention concerne un véhicule à sustentation magnétique et un ensemble de cadres de suspension associé. L'ensemble de cadres de suspension comprend multiples cadres de suspension (1) raccordés séquentiellement les uns aux autres. Chaque cadre de suspension (1) comprend deux poutres de moteur (11), quatre bras de support (12) et quatre ressorts pneumatiques (13). Un siège de montage de ressort pneumatique (125) est disposé au niveau d'une partie supérieure de chaque bras de support (12). Les sièges de montage de ressort pneumatique (125) sont des cavités présentant des ouvertures. Les ressorts pneumatiques (13) sont reçus dans les cavités respectives. L'ensemble de cadres de suspension utilise la cavité disposée sur le bras de support (12) comme siège de montage de ressort pneumatique (125), de sorte que le ressort pneumatique (13) est disposé dans le bras de support (12), ce qui permet d'éliminer le besoin d'un couvercle anti-poussière de ressort pneumatique, d'une tige de traction transversale et d'une poutre de support de bras de ressort pneumatique, ce qui permet de réduire la hauteur d'une surface supérieure du ressort pneumatique (13) et de résoudre le problème selon lequel le cadre de suspension (1) est lourd, présente un centre de gravité élevé et doit être doté d'un couvercle anti-poussière de ressort pneumatique.

一种磁浮车辆及其悬浮架组件,悬浮架组件包括依次相连的多个悬浮架(1);每个悬浮架(1)包括两个电机梁(11)、四个托臂(12)以及四个空气弹簧(13);在每个所述托臂(12)的顶部设置有一个空气弹簧安装座(125),所述空气弹簧安装座(125)为具有开口的空腔;在每个所述空腔内均容置有一个所述空气弹簧(13)。该悬浮架组件采用设置在托臂(12)上的空腔作为空气弹簧安装座(125),使空气弹簧(13)内置于托臂(12)中,不仅取消了空气弹簧防尘罩、横向拉杆和空气弹簧托臂梁,而且还能降低空气弹簧(13)顶面的高度,从而解决相关悬浮架(1)存在重量大、重心高和需要设置空气弹簧防尘罩的问题。
