The invention discloses a bogie. The bogie comprises a framework, a traction device, a primary suspension device and a secondary suspension device. The traction device comprises a first traction rod used for being hinged to the framework, a triangular supporting rod used for being connected with a framework front-end beam and a second traction rod used for being hinged to an adjacent vehicle body. The first traction rod and the second traction rod are located in the same vertical plane and both hinged to the triangular supporting rod. The first traction rod is horizontally arranged, and the end, used for being connected with the vehicle body, of the second traction rod is higher than the end, connected with the triangular supporting rod, of the second traction rod. According to the device, the combination of the double traction rods and the triangular supporting rod which are low in rate of wheel load reduction and high in adhesion utilization rate is adopted, so that a low-position traction structure is formed, and thus the vehicle body is connected with the bogie. Braking force and traction force are transmitted, and the overall adhesive property is good. Moreover, the stability of the vehicle body in the turning process can be improved. The invention further discloses transportation equipment including the bogie. Abnormal vibration is reduced, and safety and comfort are improved.
