Background
Although tubeless tires are increasingly widely used as the level of tire design increases, there is still a need for inner tires in specific environments and special operations, and there are also higher requirements for inner tires and rim strips as the conditions of use are specific. Traditional rim strip adopts the thickening design, and the production process is simple and easy, but the product percent of pass is lower, and local exhaust is not smooth, and the mould processing degree of difficulty is big, and life cycle is short, can't satisfy high load and long-time operational environment even.
Along with the continuous expansion of world demands, various engineering machinery vehicles are increasingly busy in mining areas and construction sites, and the bearing capacity is also continuously expanded. The time of replacing the tire once by the engineering truck is half a day or even longer, the weakest link in the whole tire assembly is the valve opening, and the cushion belt rubber extruded from the valve opening groove of the rim by air pressure is accelerated to deform and break or even crack to cause air leakage of the inner tube due to long-time use, huge load capacity and bad road conditions. At this time, the design of local thickening of the cushion belt can not meet the work of high air pressure, high load and high strength in the market. And the bending and aging phenomena can occur after the original cushion belt rubber directly contacts with the rim is used for a long time. To address the above dilemma, a layer of insulation may be provided between the rim and the rim strip.
For example, Chinese utility model patent (publication No. CN201291721, published: 20090819) discloses a protection device for automobile tires, and particularly relates to a tire rim strip protection wing. It includes: the tire flap protection wing comprises a wing body, and a protection cylinder is arranged on the wing body. It can avoid the extrusion of rim pore pair flap, improves the life of flap, can also prevent rivers in the tire.
However, when the structure is used, the protective wing and the rim can move mutually, so that the position of the valve moves.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, an object of the present invention is to provide a reinforcing steel sheet for a tire flap valve and a wheel, wherein a reinforcing steel sheet is disposed between a flap and a rim according to a position of the valve, and the reinforcing steel sheet is connected to the rim by a positioning portion, so as to ensure that the reinforcing steel sheet and the rim do not move relatively.
For the purpose of the utility model, the following technical scheme is adopted for implementation:
a reinforcing steel sheet for a tire cushion belt inflating valve comprises a main body part, wherein a circular truncated cone protruding upwards is arranged on the main body part; a through hole which penetrates through the circular truncated cone up and down is formed in the circular truncated cone and is used for enabling the inflating valve to penetrate out of the inner part of the tire; the outer edge of the upper part of the circular truncated cone is provided with a downward flanging which is used for pressing the pad strip on the main body part; the main body part is provided with a positioning part, and the positioning part is used for being connected with the rim and positioning the main body part on the rim.
Preferably, the reinforced steel sheet is subjected to Dacromet corrosion prevention treatment.
Preferably, the positioning part is a positioning boss protruding downwards the main body part, and the positioning boss is used for being connected with a wheel felloe on a wheel rim.
Preferably, an arrow is arranged on the positioning boss, and the arrow is used for determining the installation orientation of the valve.
A wheel comprises a rim, an outer cover, a cushion belt, an inflating valve and the reinforced steel sheet; an outer tire is arranged along the circumferential direction of the rim; the rim is provided with an inflating valve mounting opening, the inner side of the inflating valve mounting opening is provided with a reinforcing steel sheet, the inner side of the reinforcing steel sheet is provided with a cushion belt, and the inflating valve enters from the inflating valve mounting opening and penetrates through the through hole to extend into the tire.
Preferably, the rim is provided with a well matching the positioning portion.
Preferably, the wheel further comprises an inner tube.
In conclusion, the utility model has the advantages that: the positioning boss can ensure that the centers of the inflating valve and the cushion belt of the inner tube are aligned with the rim, so that deviation is avoided, the inflating valve is protected and fixed, and the service life of the tire is prolonged.

Detailed Description
As shown in fig. 1, the wheel comprises a rim 1, an outer cover 2, a reinforcing steel sheet 3, a rim strip 4, a valve 5 and an inner tube 6, wherein the outer cover 2 is arranged along the circumferential direction of the rim 1. Set up the inflating valve installing port on rim 1, the inboard of inflating valve installing port sets up reinforcing steel sheet 3, and reinforcing steel sheet 3's inboard sets up flap 4, and inflating valve 5 gets into and passes through-hole 321 from the inflating valve installing port and extends to inside the tire. The rim 1 is provided with a rim groove for connecting the reinforcing steel sheets 3.
As shown in fig. 2 and 3, the reinforcing steel sheet for the valve of the tire cushion belt comprises a main body part 31, wherein a circular truncated cone 32 protruding upwards is arranged on the main body part 31. A through hole 321 which penetrates through the circular truncated cone 32 from top to bottom is formed in the circular truncated cone, and the through hole 321 is used for the valve 5 to penetrate out of the tire. The outer edge of the upper portion of the circular truncated cone 32 is provided with a downward flange 322, and the flange 322 is used for pressing the pad strip 4 on the main body 31. The pad strip 4 and the circular truncated cone 32 are in interference fit.
