At the outer sheathed wheel hub of core wheel and pressure ring, the inner circle end face central authorities of wheel hub are provided with ring-type convex body, form annular enclosed U-shaped groove between described convex body and U-shaped space；
The most ring-type uniform multiple U-shaped rubber bodies in described U-shaped groove, U-shaped rubber bodies is interference fit in the case of wheel is zero load and between U-shaped groove, and magnitude of interference interval is the 6% ~ 14% of each position thickness of U-shaped rubber bodies；
Described U-shaped rubber bodies includes that bottom surface and two sides, the bottom surface of U-shaped rubber bodies and two sides are one-body molded, and the angle between bottom surface and two sides is 110 degree.
Described pressure ring has 12 cylindricality counter sinks along the ring-type spaced set of axial direction, offers 12 bolts hole on core wheel with cylindricality counter sink correspondence position, and pressure ring is bolted with core wheel.
The most ring-type uniform 12 U-shaped rubber bodies in described U-shaped groove, the corresponding in the longitudinal direction angle of circumference of each U-shaped rubber bodies is 20 degree.
Described wheel is provided with multiple oil filler point in the heart.
Beneficial effects of the present invention:
The present invention significantly reduces the phenomenon that traditional elastic wheel stress is concentrated, and especially in the internal force main conduction region of car wheel structure, not only meets rigidity requirement, and improves the whole service life of car wheel structure；Use U-shaped rubber bodies can significantly improve the stress concentration phenomenon under large deformation, and be conducive to heat radiation, reduce performance dispersion, thus extend active time.

Detailed description of the invention
Being further detailed the present invention below in conjunction with the accompanying drawings, track traffic damping noise reduction wheel as shown in Figure 1, Figure 2 and Figure 3, including wheel hub 1, core wheel 2 and pressure ring 3；
Described core wheel 2 outer rim is provided with core wheel convex shoulder 4, and described pressure ring 3 outer rim is provided with damages convex shoulder 5 by pressure, and pressure ring 3 is fitted in core wheel 2 side and is threadably secured, core wheel convex shoulder 4 and damage convex shoulder 5 by pressure and constitute ring-type U-shaped space；
At the outer sheathed wheel hub 1 of core wheel 2 and pressure ring 3, the inner circle end face central authorities of wheel hub 1 are provided with ring-type convex body 6, form annular enclosed U-shaped groove between described convex body 6 and U-shaped space；
The most ring-type uniform multiple U-shaped rubber bodies 7 in described U-shaped groove, U-shaped rubber bodies 7 is interference fit in the case of wheel is zero load and between U-shaped groove, and magnitude of interference interval is the 6% ~ 14% of U-shaped each position thickness of rubber bodies 7；
Described U-shaped rubber bodies 7 includes that bottom surface and two sides, the bottom surface of U-shaped rubber bodies and two sides are one-body molded, and the angle between bottom surface and two sides is 110 degree；Two sides of U-shaped rubber bodies 7 and the ring-type convex body of inner circle end face 6 of wheel hub 1 and core wheel convex shoulder 4 and pressure ring convex shoulder 5 contact, realize the axial carrying capacity of rubber bodies, not only ensure that wheel bears the driving safety under the operating mode of axial shearing force, and the effect of slowing down vibration can be played；
