The utility model provides a bicycle tire shock attenuation steel ring, abandoned the spoke in the traditional bicycle steel ring, adopted the bumper shock absorber to replace spoke support steel ring, three bumper shock absorbers along the tangential direction of hollow shaft periphery around the hollow shaft equipartition, form stable triangle-shaped bearing structure, structural stability is good, and buffering, the effect of moving away to avoid possible earthquakes is good, the bumper shock absorber can absorb and disperse the most energy when the wheel takes place to strike or bump, reduce the impact force to the human body, can improve the travelling comfort when the bicycle is ridden; the hollow shaft is used for installing a threaded shaft so as to facilitate the connection of a frame.

Preferably, the triangular plate comprises a plate body and three connecting arms uniformly arranged along the circumferential direction of the plate body, the adjacent connecting arms are in arc transition, and screw holes are formed in the connecting arms.

Preferably, the disk body and the connecting arm are of a homogeneous and integral structure.

Preferably, a connecting convex ring is arranged on the outer circumference of the hollow shaft, a screw hole is formed in the connecting convex ring, a step structure is arranged between two sides of the connecting convex ring and the hollow shaft, and bearing assembling grooves are formed in openings at two ends of the hollow shaft. The screw hole on the connecting convex ring is used for connecting a screw, so that the hollow shaft can be fixedly connected with the triangular disc.

Preferably, the corner bracket is a U-shaped bracket, connecting holes are formed in two side walls of the corner bracket, a clamping groove clamped with the wheel rim is formed in the bottom of the corner bracket, and a through hole is formed in the bottom of the clamping groove. The clamping groove is used for clamping and matching with the rim to prevent the angle frame from moving in the axial direction; the through hole is used for penetrating through the bolt to connect the angle bracket and the wheel rim; the groove on the corner bracket is used for accommodating a hanging ring on the shock absorber.

Preferably, the damper is a spring damper. The spring shock absorber has simple structure, easy obtaining and low cost.

Therefore, the utility model discloses following beneficial effect has: the utility model provides a spoke in the bicycle tire shock attenuation steel ring, has abandoned traditional bicycle steel ring, adopts the bumper shock absorber to replace spoke support steel ring, and three bumper shock absorbers form stable triangle-shaped bearing structure around the hollow shaft equipartition along the tangential direction of hollow shaft periphery, and structural stability is good, and the buffering, it is effectual to move away to avoid possible earthquakes, and the bumper shock absorber can absorb and disperse most energy when the wheel takes place to strike or bump, reduces the impact force to the human body, travelling comfort when can improving the bicycle and ride.
