The invention discloses a bogie of a low-floor tramcar. The bogie comprises a wheel pair, a framework, an axle box device, a secondary suspension and a primary suspension, the wheel pairs comprise axles and wheels, the axle box devices are arranged on the axles and located on the inner sides of the wheels, and the two axle box devices on each wheel pair are symmetrically arranged along the longitudinal axis of the framework. An axle box body of the axle box device is provided with a first connecting end rotationally connected with an axle, a second connecting end arranged above a framework, and a connecting middle section connected between the first connecting end and the second connecting end and connected with the framework; a primary suspension is formed between the second connecting end and the upper surface of the framework; one side of the axle box body is arranged in the wheel in an intrusive mode, and the other side of the axle box body obliquely extends from the first connecting end to the second connecting end, so that the two opposite axle box devices on the axle are located on the longitudinal axis side of the framework to form a horn-shaped structure. The bogie meets the use requirement that the width of a vehicle body passageway is not smaller than 600 mm.
本发明公开了一种低地板有轨电车转向架,其包括轮对、构架、轴箱装置、二系悬挂、一系悬挂;轮对包括车轴和车轮,轴箱装置装设于车轴位于车轮内侧,且每组轮对上的两个轴箱装置沿构架纵向轴线对称设置;轴箱装置的轴箱体具有与车轴旋转连接的第一连接端和设置在构架上方的第二连接端、以及连接在第一连接端和第二连接端之间并与构架连接的连接中段;第二连接端与构架上表面之间形成一系悬挂;轴箱体一侧以侵入的形式置于车轮内部,轴箱体另一侧从第一连接端倾斜地朝向第二连接端延伸,以使车轴上相对的两个轴箱装置位于构架纵向轴线侧形成喇叭形构造,本发明通过轴箱体和车轮配合避让车体,使该转向架实现了满足车体过道宽度不小于600mm的使用需求。
