Description

Technical Field

[0001] The utility model relates to the field of steel wheels, in particular to a steel wheel structure. Background Art

[0002] High-speed engineering vehicles, car cranes, fire trucks, military off-road vehicles, etc. need to use steel wheels. Due to the heavy weight of the vehicle, in order to extend the service life of the wheel, a high-strength wheel structure is required. Among them, the "high-strength tire-protecting steel wheel" disclosed in the application number "CN201820227186.8" is also an increasingly mature technology. Its "setting of air inlet holes, air outlet holes and heat dissipation duct springs is conducive to reducing the heat accumulated inside the tire, keeping the tire in a certain constant temperature state, avoiding excessive heat inside the tire, causing damage to the tire, and causing injury to the driver. Specifically, when When the wheel rotates, air enters the heat dissipation channel from the air inlet hole, and the heat dissipation channel is discharged from the air outlet hole along with the air, which plays a role in reducing the internal temperature of both sides of the tire and effectively protecting the tire. However, the wheel structure still has the following defects during use: the wheel structure can indeed achieve heat dissipation effect through the air inlet hole, the air outlet hole and the heat dissipation channel spring, but the existence of the air outlet hole, the air inlet hole and the heat dissipation channel spring of the wheel structure will affect the compressive strength of the wheel. Based on this, it is necessary to provide a wheel structure that can not only perform heat dissipation operation, but also enhance compressive strength and extend service life. Utility Model Content

[0003] The embodiment of the utility model provides a steel wheel structure, which aims to solve the problem that the existing wheel structure is affected in terms of its own strength while dissipating heat, thereby affecting the service life of the wheel structure.

[0004] To achieve the above-mentioned purpose, the utility model provides a steel wheel structure, including a wheel assembly;

[0005] Wherein, the wheel assembly includes a hub, rims are fixedly connected to both sides of the hub, the side surface of the rim is connected to the flange, spokes are welded inside the hub, nut seats are fixedly connected inside the spokes, a center hole and a plurality of screw holes are respectively provided on the nut seats, a plurality of air holes are equidistantly provided on the surface of the spokes, and a valve hole is provided on the surface of the rim.

[0006] As a preferred solution of the present invention, the wheel is a steel structure, the calibrated diameter of the wheel is 380.5 feet, and the diameter of the rim is 16 feet.

[0007] As a preferred solution of the present utility model, the ET value of the wheel hub is 38.5.

[0008] As a preferred solution of the utility model, the spoke is an arc-shaped conical surface structure.

[0009] As a preferred solution of the utility model, the wheel surface is coated with a black primer, the black primer is a cathode electrophoretic paint, and the thickness of the black primer is ≥25 μm.

[0010] As a preferred solution of the utility model, the valve hole is located within the range of ±2mm from the center line of the air hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When in use, heat dissipation can be achieved through several air holes on the surface of the spokes. The ET value of the hub indicates the center offset value of the hub, which represents the deviation distance from the center line of the hub to the fixing surface of the hub. The larger the positive value of the center offset, the more the hub will be biased inward on the vehicle body, and the more the hub is biased inward, the more it can bear the gravity of the vehicle body. At the same time, the steel wheel structure combined with the arc-shaped conical spokes can enhance its overall compressive strength, and the 25-micron thick black primer can protect the wheel structure and further enhance the compressive strength of the wheel structure. Compared with the heat dissipation structure in the prior art "a high-strength tire protection steel wheel", the utility model can not only achieve heat dissipation through the cooperation of the above-mentioned structures, but also enhance the comprehensive compressive strength of the wheel structure, thereby extending the service life of the wheel structure.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-Figure 2 , the utility model provides a steel wheel structure, including a wheel assembly 100;

[0018] The wheel assembly 100 includes a hub 101, with rims 102 fixedly connected to both sides of the hub 101, a flange 103 connected to the side surface of the rim 102, spokes 104 welded to the inside of the hub 101, nut seats 105 fixedly connected to the inside of the spokes 104, the nut seats 105 are respectively provided with a center hole 106 and a plurality of screw holes 107, a plurality of air holes 108 are equidistantly provided on the surface of the spokes 104, and a valve hole 109 is provided on the surface of the rim 102.

[0019] In a specific embodiment, the plurality of air holes 108 arranged on the surface of the wheel assembly 100 can not only achieve a heat dissipation effect, but also enhance the overall comprehensive compressive strength of the wheel structure, thereby extending the service life of the wheel structure. When in use, the plurality of air holes 108 on the surface of the spoke 104 can discharge the heat generated during the rotation of the wheel, thereby achieving the purpose of heat dissipation. The larger the positive value of the ET value of the hub 101, the more the hub 101 shifts inward, thereby being able to fully bear the gravity of the vehicle body. At this time, the wheel structure with a steel structure can enhance its own hardness and compressive strength, and the spoke 104 with an arc-shaped cone structure can diffuse the pressure of the vehicle body outward and divide it equally on the entire wheel, thereby further enhancing the compressive strength, thereby extending the service life of the wheel structure.

[0020] See also Figure 2 The wheel is made of steel, the nominal diameter of the wheel is 380.5 feet, and the diameter of the rim 102 is 16 feet.

[0021] In a specific embodiment, a wheel with a calibrated diameter of 380.5 feet can bear the weight of the vehicle body well. The rim 102R16 represents a radial tire. The structural feature of the radial tire is mainly reflected in that the belt layer is the main load-bearing component. The 16-foot diameter of the rim 102 can enhance its own compressive strength, thereby extending the service life of the wheel structure.

[0022] See also Figure 2 , the ET value of hub 101 is 38.5.

[0023] In a specific embodiment, the larger the positive value of ET is, the more the wheel hub 101 is offset toward the inside of the vehicle body. The wheel hub 101 with an ET value of 38.5 can bear the weight of the vehicle body to the maximum extent, thereby improving the stability of the vehicle body during driving.

[0024] See also Figure 2 , the spoke 104 is an arc-shaped conical structure

[0025] In a specific embodiment, the spokes 104 with an arc-shaped conical surface structure can diffuse the pressure of the vehicle body to the outside, so that the overall structure of the wheel evenly distributes the pressure, thereby enhancing the compressive strength of the wheel structure.

[0026] See also Figure 2 The wheel surface is coated with black primer, which is cathodic electrophoretic paint, and the thickness of the black primer is ≥25μm.

[0027] In a specific embodiment, a cathodic electrophoretic paint with a thickness of 25 μm can protect the wheel and prevent the wheel structure from being worn and damaged.

[0028] See also Figure 2 The valve hole 109 is located within the range of ±2mm from the center line of the air hole 108.

[0029] In a specific embodiment, the valve hole 109 is used to limit the tire valve.

[0030] Working principle: When in use, the several air holes 108 on the surface of the spoke 104 can achieve heat dissipation effect, preventing the wheel from being damaged due to excessive heat during driving. At the same time, the steel hub 101 and the spoke 104 with an arc-shaped conical surface structure can further enhance the overall compressive strength of the wheel. When the wheel is under pressure, the spoke 104 can diffuse the pressure to the entire wheel, significantly enhancing the compressive strength of the wheel. The wheel can be protected with primer to avoid wheel wear, thereby enhancing the compressive resistance of the wheel structure, thereby extending the service life of the wheel structure.
