The invention discloses a rear drive transmission shaft supporting piece of an integrated bidirectionally-vulcanized structure. The rear drive transmission shaft supporting piece of the integrated bidirectionally-vulcanized structure comprises a middle supporting installation support, a middle supporting bearing and middle supporting main springs. The two middle supporting main springs are in the same shape and are symmetrically arranged, each middle supporting main spring is of a rotary body structure, and the radial section of each middle supporting main spring is of a C-shaped structure. Each middle supporting main spring comprises an edge side and a bent side. The edge sides of the two middle supporting main springs are arranged oppositely. An inner side portion and an outer side portion which are both of an annular structure are arranged between the edge side and the bent side of each middle supporting main spring. Connecting portions used for connecting the inner side portions with the outer side portions are arranged on the bent sides of the middle supporting main springs. Radial protrusions of annular structures are arranged on the edge sides of the inner side portions towards the outer side portions. The rear drive transmission shaft supporting piece of the integrated bidirectionally-vulcanized structure can overcome the defects of the prior art and meet actual use requirements. The invention further discloses a machining method of the rear drive transmission shaft supporting piece of the integrated bidirectionally-vulcanized structure.
