The invention discloses a low-floor tramcar wheel set and a bogie with the same, and the wheel set comprises an axle and wheels arranged at the two ends of the axle; the wheels are elastic wheels; hubs of the wheels are in interference fit with the axle; the hub is sleeved with a rim, an elastic element is installed between the hub and the rim, and the hub is further sleeved with a pressing ring used for synchronously bearing the elastic element with the hub. The hub comprises a body and a web plate formed on the outer portion of the body in the circumferential direction. According to the bogie, the wheels and the axle box devices are matched to avoid a vehicle body, the bogie meets the use requirement that the aisle width of the vehicle body is not smaller than 600 mm, the wheels and the axles are installed in an interference fit mode, the axle box devices are allowed to intrude into the wheels, the axle box devices are not prone to intruding into the wheels, and therefore the bogie is not prone to being damaged, and the service life of the bogie is prolonged. The structure reliability is good, the use safety coefficient is high, and the space utilization rate between the two wheels in the wheel set is greatly increased.

    本发明公开了一种低地板有轨电车轮对及具有该轮对的转向架,其中,轮对包括:车轴和装设在所述车轴两端的车轮;所述车轮为弹性车轮;所述车轮的轮毂与所述车轴过盈配合;所述轮毂外部套有轮辋,所述轮毂和所述轮辋之间安装有弹性元件,且所述轮毂还套设有用于与其同步承托所述弹性元件的压环;所述轮毂包括本体和周向形成在所述本体外部的腹板;所述腹板一侧形成有类C型的凹槽结构,用于容纳轴箱装置,本发明通过车轮和轴箱装置配合避让车体,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,车轮与车轴采用过盈配合的安装方式、并允许轴箱装置侵入车轮中,结构可靠性好、使用安全系数高,且极大地提高了轮对中两个车轮之间的空间利用率。
