Abstract

The invention provides a heavy track rear hub bearing combination which comprises a hub and a bearing component arranged inside the hub, wherein the bearing component is of an integrated structure and comprises an outer ring, two inner rings, a partitioning ring, two holding racks and two rows of conical rollers; the two inner rings are arranged inside the outer ring at an interval through the partitioning ring; a chamber is formed among the outer walls of the inner rings, the inner wall of the partitioning ring and the inner wall of the outer ring; the chamber comprises a sealing part, a first mounting part, an oil channel and a second mounting part which are arranged in sequence; the two rows of conical rollers are respectively arranged at the first mounting part and the second mounting part through the two holding racks; the sealing part is internally provided with an oil seal for plugging the end opening of the chamber. The bearing combination has the advantages that the bearing combination is good in rigidity, is high inbearing capability, is long in service life, does not rotate relatively to the large outer diameter of the hub, cannot cause friction, and increases the contact area; the hub is not easy to abrade, and the hub is not concave.

Description

technical field [0001] The invention relates to heavy truck components, in particular to a heavy truck rear hub bearing assembly. Background technique [0002] The structure of the traditional heavy-duty truck hub bearing assembly has the following problems: 1.
