[0002] At present, the rims of heavy construction machinery vehicles such as all-terrain cranes in China are mainly steel rims. The steel rims have a simple structure, are easy to process, and have a low cost. However, the disadvantage of the large weight of the steel rims will gradually be replaced in the future development process of lightweight and energy-saving consumption of heavy construction machinery vehicles. The steel rims are heavy and bulky. After the whole machine is assembled, the unsprung weight and the weight of the whole machine both increase significantly, affecting the overall design requirements and the braking and driving performance of the vehicle.

[0003] The structure of the existing steel rims is mainly formed by splicing and welding. For example, the connection between the web and the rim body is mainly achieved by butt welding. However, due to the environmental space and operation accuracy, welding defects such as welding pores, welding slag, and micro-cracks are likely to occur, resulting in mechanical property loss problems, affecting the working effect of the device. At the same time, there is no sealing device between the rim body and the retaining ring, making it difficult to ensure their close fit and affecting the airtightness of the wheel. Summary of the Utility Model

[0026] As Figures 1-3As shown in the figure, the present utility model provides a three-piece structure rim, including a rim body 1, a retaining seat ring 2, a locking ring 3 and a valve 8. The retaining seat ring 2 is sleeved outside the rim body 1. Both the locking ring 3 and the valve 8 are detachably connected to the rim body 1. The locking ring 3 is used to block the retaining seat ring 2. The rim body 1 includes a rim base 4. One side of the rim base 4 is integrally connected with a rim flange 5. On the other side of the rim base 4, a locking ring groove 6 for fixing the locking ring 3 is opened at the top. Inside the rim base 4, a spoke plate 7 is integrally connected. On one side of the outer wall of the spoke plate 7, a plurality of heat dissipation holes 12 are evenly opened. The retaining seat ring 2 is of a Z-shaped structure. An arc groove is opened on the outer wall of the rim base 4 and the inner wall of the retaining seat ring 2. When the retaining seat ring 2 is closely attached to the locking ring 3, the two arc grooves can be combined to form a sealing ring groove 9 for accommodating a sealing ring.

[0027] Specifically, the sealing ring is installed in the sealing ring groove 9 formed by the rim body 1 and the retaining seat ring 2. The locking ring 3 is stuck in the locking ring groove 6 of the rim body 1. When the tire is inflated to the normal air pressure, under the action of the air pressure, the tire bead is closely attached to the rim flange 5 of the rim body 1 and the retaining seat ring 2. At the same time, under the locking action of the locking ring 3, the action of the tire air pressure and the sealing action of the sealing ring, the retaining seat ring 2 is closely attached to the rim base 4 of the rim body 1, ensuring the airtightness of the entire wheel. The above-mentioned rim can be used in the running system of heavy construction machinery vehicles, such as all-terrain cranes, etc. After the tire is sleeved on the rim, ensure that the locking ring 3 is in the locking ring groove 6, and inflate it through the valve 8 to make the rim and the tire closely attached, and then assemble it onto the axle as a whole. The rim body 1 is made of aluminum alloy and is formed by integral spinning, without welding, avoiding the problem of mechanical property loss caused by welding defects such as welding pores, welding slag, and micro-cracks. The rim has higher reliability and is convenient for disassembly and maintenance. The heat dissipation holes 12 are used to realize the heat dissipation work of the rim body 1. The plurality of heat dissipation holes 12 are circularly distributed.

[0028] Such as Figure 3 As shown in the figure, in the present application, by integrally forming the rim base 4 and the spoke plate 7, the problem of mechanical property loss caused by welding defects such as welding pores, welding slag, and micro-cracks is avoided, and the reliability of the rim is higher, ensuring the working effect of the device. When the tire is inflated to the normal air pressure in the present application, the retaining seat ring 2 is closely attached to the rim base 4 through the sealing ring, ensuring the airtightness of the entire wheel. At the same time, through the cooperation of the sealing ring and the sealing ring groove 9, a certain positioning effect is achieved on the retaining seat ring 2, ensuring the practicability of the device.

[0029] In one embodiment, the material of the rim body 1 is aluminum alloy.

[0030] Specifically, the rim body 1 is made of aluminum alloy. The rim body 1 is of an integral structure and is formed by integral spinning, which greatly reduces its own weight, realizes the lightweight index of the wheel, and solves the related problems of the large weight of the current steel rim and the overweight total matching axle load; the rim body 1 is made of aluminum alloy. Through the integral spinning forming process, the performance index of the material is improved. At the same time, the aluminum alloy has good heat transfer performance. During the driving process of the vehicle, a large amount of heat will be generated between the brake and the friction plate and between the tire and the ground. If the heat cannot be dissipated in time, it will lead to a decline in the braking performance of the vehicle and potential safety hazards such as tire blowouts. The aluminum alloy wheel can dissipate this heat faster; at the same time, the aluminum alloy wheel is easier to form, has higher precision, smaller out-of-roundness and radial runout, and smaller vehicle vibration; the surface treatment and polishing of the aluminum alloy make it more beautiful and have good corrosion resistance, making it have the advantages of beautiful appearance, light weight, and good heat dissipation of the aluminum alloy rim.

[0031] In an embodiment, the rim body 1 is used to match a 525 / 80R25 tire; an air valve mounting hole 10 for mounting the air valve 8 is provided on the outer wall of the rim bottom 4; a plurality of bolt mounting holes 11 are evenly provided on one side of the outer wall of the spoke plate 7, and the plurality of bolt mounting holes 11 are circularly distributed.

[0032] In an embodiment, the materials of the retaining seat ring 2 and the lock ring 3 are both steel; optionally, the material of the retaining seat ring 2 is 380CL wheel steel, and the material of the lock ring 3 is Q345B steel. The steel structure improves the overall structural strength of the rim and ensures the service life of the rim; the air valve 8 is installed on the structure of the rim body 1, which has a simple structure, convenient assembly, and light weight. The rim body 1 is integrally formed by spinning aluminum alloy, the retaining seat ring 2 is forged from 380CL wheel steel, and the lock ring 3 is formed by forging Q345B. The rim of the present invention combines the advantages of light weight and high precision of the aluminum alloy rim, and also has the characteristics of simple structure, low cost, and long service life of the three-piece rim. Compared with the all-aluminum alloy rim, the cost of this rim is reduced. Embodiment Two:
