The technical scheme of the utility model by wheel hub, two clamping rings and wheel center constitution, two clamping rings pass through the bolt pressure and locate on the wheel center, rubber component sets up on wheel hub's interior circumference, its characterized in that: the rubber component is characterized in that a plurality of grooves are uniformly formed in two sides of the outer edge of the wheel center, the grooves in the two sides are arranged in a staggered mode, a supporting pressing block is arranged in each groove, the cross section of the rubber component is inverted X-shaped, and supporting blocks are arranged on the inner side of the rubber component.
Description
Technical Field
The utility model relates to a rail transit technical field, concretely relates to elasticity wheel with X type rubber component.
Background
With the development of urban light rail traffic, noise generated by running light rail vehicles on urban ground or viaducts has become a prominent problem. To address this problem, resilient wheels have found widespread use in light rail vehicles around the world.
An elastic unit is arranged between the wheel center and the wheel rim of the elastic wheel, and the wheel rim is elastically supported on the wheel, so that the curve noise can be effectively reduced, the track impact can be reduced, the wheel rail abrasion can be reduced, and the service life of the line vehicle can be prolonged. Most of the rubber elements are arranged in a U shape (application number: 2018114304918), and the rubber elements have excellent performance in vibration and noise reduction, but have complex structure and high cost.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides an elasticity wheel with X type rubber component, it improves rubber component, further strengthens wheel performance and anti inefficacy ability to with the briquetting of passing the wheel center both sides accurate control its decrement in order to guarantee the performance of elasticity wheel.
For solving the problems existing in the prior art, the technical scheme of the utility model is that: the utility model provides an elasticity wheel with X type rubber component comprises wheel hub, two clamping rings and wheel center, two clamping rings pass through the bolt pressure and locate on the wheel center, rubber component sets up on wheel hub's interior circumference, its characterized in that: the rubber component is characterized in that a plurality of grooves are uniformly formed in two sides of the outer edge of the wheel center, the grooves in the two sides are arranged in a staggered mode, a supporting pressing block is arranged in each groove, the cross section of the rubber component is inverted X-shaped, and supporting blocks are arranged on the inner side of the rubber component.
Compared with the prior art, the utility model has the advantages as follows:
the utility model discloses improve original "U" type rubber component into "X" type, adjust axial and radial matching rigidity through the size that changes the both sides contained angle to this rubber structure has thickened intermediate level thickness, better bearing load of ability.
The utility model discloses set up in the outer fringe both sides of wheel center and support the briquetting, come the compression capacity of accurate control rubber component and simplify the wheel assembly step, reduce the assembly degree of difficulty and cost.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment provides an elastic wheel (refer to fig. 1-9) with an X-shaped rubber element, which comprises a wheel hub 1, two pressure rings 2 and a wheel center 7, wherein the two pressure rings 2 are pressed on the wheel center 7 through bolts 3, the rubber element 4 is arranged on the inner circumference of the wheel hub 1, a plurality of grooves are uniformly arranged on the two sides of the outer edge of the wheel center 7, the grooves on the two sides are arranged in a staggered mode, a supporting pressing block 6 is arranged in each groove, the cross section of the rubber element 4 is of an inverted X shape, and a supporting block 5 is arranged on the inner side of the rubber element.
The inner ring of the hub 1 is provided with 12 grooves, the rubber element 4 is arranged in the 12 grooves of the hub 1, the inner wall groove of the rubber element 4 is internally provided with the supporting block 5, and the rubber element 4 is in interference fit with the inner wall of the cavity between the hubs under the condition of no load of the wheel.
When the rubber element 4 fails, the boss of the wheel hub is matched with the supporting block 5 to transmit torque continuously, so that the wheel hub 1, the compression ring 2 and the wheel center 3 are integrally in a rigid wheel structure, and stable operation of a train is guaranteed.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
