The invention provides a bolt assembly of a drive rear axle wheel of an automobile and an assembling method of the drive rear axle wheel, belongs to the technical field of manufacturing of drive axles of automobiles and mainly solves the problem that automobile bolts are broken frequently in batches in the application of EQ153 drive rear axles to engineering vehicles. The bolt assembly is mainly characterized in that the diameter of a first section of a bolt shank, at the position matching rims, of a wheel bolt is phi 30mm, the specification of corresponding threads is M20*2, and the inner end of the first section of the bolt shank is provided with a positioning step surface; the diameter of the position, matching a hub, of the wheel bolt is phi 22, and the specification of threads is M22*1.5; the bolt assembly also comprises a two-sided spherical washer. The assembling method comprises the following steps of (1) pressing one end of the wheel bolt into a bolt hole of the hub to tightly match the hub, and assembling a brake drum; (2) thrusting the inner rim to be fitted to the surface of the hub, arranging the two-sided spherical washer between the two rims, and assembling the outer rim; and (3) sequentially tightening wheel nuts diagonally. By applying the bolt assembly of the drive rear axle wheel of the automobile and the assembling method of the drive rear axle wheel, the shear resistance capacity of the wheel bolt is enhanced, installation convenience of the rim is improved, and the bolt assembly of the drive rear axle wheel of the automobile and the assembling method of the drive rear axle wheel are mainly applied to bolt assemblies of drive rear axle wheels of automobiles.
