The utility model relates to a two-level rigidity shaft box rubber spring and belongs to railway vehicle accessories. The two-level rigidity shaft box rubber spring comprises a mandrel, a partitioning plate and outer sleeves. The partitioning plate is arranged on the mandrel. The outer sleeves are arranged on the partitioning plate and the mandrel. First rubber is arranged on the mandrel, the partitioning plate and the outer sleeves in a vulcanization mode. According to a composite spring, second rubber is arranged between an upper steel plate and a lower steel plate in a vulcanization mode. The two-level rigidity shaft box rubber spring has the advantages that on the basis of an existing rubber spring, the composite spring is added, and two-level rigidity is formed. According to the design, under the effect of hollow vehicle and heavy vehicle loading, the fact that the outer sleeves 5 are in frequent contact with the composite spring to cause impact vibration during moving can be guaranteed. Two-level rigidity combination of the rubber spring is achieved, and hollow-heavy-two-level rigidity requirements of large-difference wagon hollow-heavy vehicle weights are met.
