The invention discloses a bogie. The bogie comprises a framework, a single stage suspension device and a two-stage suspense device; the two-stage suspense device comprises two sets of rubber stacks which are used for being connected with a vehicle body chassis sleeper beam, and the two sets of the rubber stacks are symmetrically arranged on the two sides of the transverse center line of the framework; each set of rubber stacks comprises at least two rubber packs, the transverse center line of each rubber stack is close to the transverse center line relative to a the transverse center line of a single stage spring, and the distances of all the transverse center lines of all the rubber stacks and the transverse center line of the framework are equal. According to the transportation equipment, the transverse center lines of the rubber stacks are closer to the transverse center line of the framework compared with the center line of the single stage spring, that is to say, the transverse span length of a two-stage spring is smaller than the transverse span length of the single stage spring, and when a locomotive passes through a curve, the safety is improved. The invention further discloses transportation equipment of the bogie, the torsional rigidity of the bogie and the vehicle body is small, and the stability and the safety are high during turning.
