The invention relates to a mixed-type rim lubrication block comprising a block body. The block body comprises a smearing block and an oil injection block. One side, which is in contact with a rim, of the block body is provided with a smearing groove which extends to the inside of the smearing block. A plurality of oil injection holes are formed in the oil injection block and are filled with lubricating oil. The oil injection holes are communicated with the smearing groove. The mixed-type rim lubrication block overcomes the shortcomings of the prior art, combines conventional dry lubrication and wet lubrication, and absorbs the advantages of the two conventional technologies; the lubrication block comprises the smearing block and the oil injection block and the oil injection block is internally provided with the oil injection holes; grease placed in the oil injection holes can be prevented from curing, so that the cost is reduced by more than 20% compared with that of pure grease lubrication; the problems of dry lubrication, such as crack, breakage and dust formation, are solved; the mixed-type rim lubrication block enables relatively thick lubrication films to be formed, thereby improving the lubrication effect.
