Title (EN) HOLLOW AXLE STRUCTURE AND WHEEL SET
(FR) STRUCTURE D'ESSIEU CREUX ET TRAIN DE ROUES
(ZH) 一种空心轴桥结构及轮对
Abstract:
(EN) Disclosed is a wheel set, comprising an axle (19), which is mounted inside a hole of a hub (3) of a first wheel (1) and a second wheel (21) respectively via a corresponding bearing (6); the axle (19) is a hollow pipe-shaped structure, and a torsion bar (20) is fitted inside the axle (19); a drive plate (7) is mounted on an outer end of the hub (3) of the wheels (1, 21), and an inner end face of the drive plate (7) is fixedly connected with an end part of the torsion bar (20) to realize the rotation of the left and right wheels (1, 21). The wheel set improves the force applied to the vehicle axle and when compared to a traditional wheel set, the mass of the wheel set is reduced approximately 20%-30%. Further disclosed is a hollow axle structure.
(FR) L'invention concerne un train de roues comprenant un essieu (19), qui est monté à l'intérieur d'un trou d'un moyeu (3) d'une première roue et d'une seconde roue (21) respectivement par l'intermédiaire d'un palier correspondant (6); l'essieu (19) présente une structure en forme de tube creux, et une barre de torsion (20) est ajustée à l'intérieur de l'essieu (19); une plaque d'entraînement (7) est montée sur une extrémité externe du moyeu (3) des roues (1, 21), et une face d'extrémité interne de la plaque d'entraînement (7) est fixement raccordée à une partie d'extrémité de la barre de torsion (20) pour réaliser la rotation des roues gauche et droite (1, 21). Le train de roues augmente la force appliquée sur l'essieu de véhicule et par rapport à un train de roues classique, la masse du train de roues est réduite d'environ 20%-30%. L'invention concerne en outre une structure d'essieu creux.
(ZH) 一种轮对,包括轴桥(19),分别通过相应轴承(6)装在第一车轮(1)和第二车轮(21)的轮毂(3)孔内;轴桥(19)为空心管状结构,轴桥(19)内套装有一根扭杆(20);车轮(1,21)轮毂(3)外端装有传动盘(7),传动盘(7)的内端面与扭杆(20)的端部固定相连,实现了左右车轮(1,21)的转动。该轮对改善了车轴受力且质量相比传统轮对减少约20%-30%。还公开一种空心轴桥结构。
