the utility model provides a two torsion beam formula shaft bushing, includes shaft bushing, inner tube, retaining ring, the ring channel has been seted up in the middle section of shaft bushing internal surface, the inside fixedly connected with spring of ring channel, the internal thread has all been seted up at both ends about the shaft bushing internal surface, the inner tube is located the inside of shaft bushing, the middle section fixedly connected with bulge loop of inner tube surface, retaining ring fixed connection is respectively at both ends about the shaft bushing, the external screw thread has been seted up to the surface of retaining ring one end, the rivet has all been pegged graft at the upper and lower both ends of retaining ring, the one end of rivet runs through the retaining ring and pegs graft with the shaft bushing, it has the rubber circle.

Further, the internal thread is matched with the external thread.

Furthermore, the number of the rubber rings is two, and the rubber rings are respectively positioned on the left side and the right side of the convex ring.

Furthermore, the convex ring is positioned right below the annular groove, and the outer surface of the convex ring is attached to the top of the spring.

Further, the groove width of the convex ring is larger than the transverse width of the convex ring.

Compared with the prior art, the utility model discloses the beneficial effect who realizes:

through the spring in the ring channel, can improve the radial shock absorbing capacity of bushing, through the rubber circle of bulge loop both sides, can improve the axial buffering and hit the ability to this life that can improve bushing.
