Specific embodiment
As Figure 1-10 shows, the invention discloses a kind of Novel transmission axle support structures, including rubber spring 1, rubber master
The outer metalwork 3 of metalwork 2, rubber spring in spring, the rubber spring 1 are mounted in the rubber spring metalwork 2 and described
Between the outer metalwork 3 of rubber spring, hollow in circular arc inside the rubber spring 1, metalwork 2 is located at institute in the rubber spring
It states at 1 inside annulus of rubber spring, the outer metalwork 3 of the rubber spring is located at the 1 outside annulus of rubber spring, the mark
Fiducial axis holds 8 and is mounted on the rubber spring 1, arc transition and hollow structure, it is ensured that product rigidity property；The rubber
Main 1 structure of spring is realized by dedicated vulcanization of rubber mold.
The outer metalwork 3 of metalwork 2, the rubber spring is distinguished rounded step-like in the rubber spring, and the rubber
Through-hole is equipped in the main spring of glue around metalwork 2, the outer metalwork 3 of the rubber spring is equipped with drainage hole；The rubber spring 1 is
Off-centre operation structure, it is ensured that product after mounting, when it being made to be driven axis static load, reaches concentric.
The Novel transmission axle support structure includes Front oil seal 4, and the Front oil seal 4 is mounted on 1 front end of rubber spring, institute
The tapered corrugated of Front oil seal 4 is stated, the Front oil seal 4 is equipped with twice lip.
