The invention provides a low-floor tramcar bogie. The low-floor tramcar bogie comprises a framework, a swing bolster, a drafting device connected with a car body, a shaft box, a wheel set, a driving device, a foundation brake device, a magnetic track brake device, a primary suspension, a secondary suspension, a dragging device, a stone sweeper and a sand scattering device. The framework comprises side beams and end beams, a cross beam is arranged between the side beams and provided with a driving motor fixing plate and a positioning block, a positioning protrusion is arranged on the positioning block, a driving motor of the driving device is fixed to the driving motor fixing plate, positioning is conducted through the positioning protrusion and a positioning groove, and a cantilever of the driving motor is hung on a transmission shaft of the wheel set. A side bearing box is arranged in the swing bolster, and a catching groove is formed in the edge of the side bearing box. The dragging device connected with the car body comprises an installing plate, a connecting pin, a gasket and a pin shaft. A gap is formed between the pin shaft and the gasket. The magnetic track brake device conducts limiting operation through a magnetic track brake limiting device. By the adoption of the structure, the strength of the framework is improved, the transverse motion amplitude of the swing bolster relative to the framework can be reduced, and the driving device can be reliably supported and fixed.
