The invention provides a bogie frame bearing wheel buffering device capable of being packaged. An upper shell body and a lower shell body are laminated to form a sealed shell and installed on a frame. One end of a bearing wheel arm I is hinged to a bearing wheel I. A connecting shaft I is fixed to the other end of the bearing wheel arm I. One end, away from the bearing wheel arm I, of the connecting shaft I penetrates through the shell and extends into the shell. A pinion is arranged in the shell and fixed to the connecting shaft I. A swing arm I is fixedly connected to the pinion. A main gear with the same connecting mode is meshed with the pinion. Protrusions are arranged at one end, away from the pinion, of the swing arm I and one end, away from the main gear, of a swing arm II respectively. A spring is arranged between the protrusions of the swing arm I and the swing arm II in a sleeving mode. The buffering device is practical for general crawler wheel vehicles, and high in universality. The device is a closed device and can protect the spring. According to the device, the two gears with the large radius difference are utilized, a transmission ratio is increased, and the device assists in increasing the deformation quantity of the spring and can absorb strenuous vibration.
