The invention provides an axle type independent wheel set with a caster angle. The axle type independent wheel set comprises independent rotating wheels, short axles, crank arm beams, axle head shaking grooves, a guide rod and an axle. Each independent rotating wheel is connected with one short axle through a rotating pair, and each short axle is fixedly connected with one crank arm beam; two sides of the axle bridge are respectively provided with an axle head shaking groove; each wheel shaft head shaking groove is vertically arranged, a mounting hole is formed in the groove wall, and the wheel shaft head shaking groove is in pin joint with the crank arm beam through the mounting hole; the connecting line of the centers of the mounting holes of the axle oscillating grooves is called as a spindle pin line, and the spindle pin line and the vertical line form a caster angle, so that the axle oscillating grooves are integrally arranged in an inclined mode. According to the axle type independent wheel set, the wheels can rotate independently, and the axle is concave downwards, so that the floor height of a train body can be reduced, and a 100% low floor is achieved. The wheels on the two sides can steer synchronously, a spindle pin line inclines forwards, the guiding performance of an independent wheel system is improved, abrasion of wheel rims is reduced, and the structure is simple and novel.

    本发明提供一种具有后倾角的轴桥式独立轮副,包括独立旋转车轮、短车轴、曲臂梁和轮轴摇头槽,以及导向杆和轴桥。每个独立旋转车轮与一个短车轴通过转动副连接,每个短车轴与一个曲臂梁固定连接;轴桥两侧分别安装一个轮轴摇头槽;每个轮轴摇头槽竖向布置,槽壁具有安装孔,并通过该安装孔与曲臂梁销接;每个轮轴摇头槽的安装孔的中心连线被称为主轴销线,该主轴销线与垂线具有后倾角,使轮轴摇头槽整体倾斜布置。本轴桥式独立轮副,车轮能够独立旋转,轴桥呈下凹形,可以降低列车车体地板高度,从而达到100%低地板。两侧车轮可以同步转向,主轴销线前倾,改善了独立车轮系统的导向性能,降低车轮轮缘的磨耗,结构简单新颖。
