The virtual track rubber wheel low-floor bogie comprises a framework, and the framework is provided with two sets of cross beams and suspension longitudinal beams arranged in the middles of the two sets of cross beams; the damping mechanisms are connected to the bottom surfaces of the two ends of the cross beam through spherical hinges, and each damping mechanism comprises two spring dampers; the wheel pair comprises an axle and wheels; the axle is connected with the damping mechanism through a cylindrical surface pair, and the wheels are arranged on the outer side of the cylindrical surface pair. Wherein the two groups of opposite damping mechanisms below the two groups of cross beams are arranged in a splayed shape; the two spring shock absorbers of each group of shock absorption mechanism are arranged in a splayed shape; the turning angle of the axle is 0-15 degrees, and the inclination angle of the axle is 0-5 degrees. The bogie is small in occupied space, suitable for a low-floor vehicle body, good in damping performance and capable of achieving self-aligning; the structure is flexible, and a plurality of carriages can be manufactured based on the structure; the device is simple in structure, low in manufacturing cost, easy to repair and low in maintenance cost.
