Description

Technical Field

[0001] This invention relates to a vacuum-insulated truck and bus wheel rim, its processing method, and its application, belonging to the field of vehicle wheel rim technology. Background Technology

[0002] The wheel rim is a crucial component connecting the tire and the axle. When the vehicle is moving, the power from the axle is transmitted to the tire through the rim; similarly, when the vehicle brakes, the braking force from the axle is also transmitted to the tire through the rim. Mining vehicles and dump trucks, due to their heavy loads and frequent braking, experience extremely high brake disc temperatures (sometimes reaching 120-200℃). These temperatures are transmitted through the axle to the rim and finally to the tire bead. Prolonged exposure to these high temperatures causes the rubber in the bead to age and fail, easily leading to problems like tire blowouts. Currently, there are two ways to address this high-temperature damage: one is to improve heat dissipation. A common method is to install water sprinklers around the wheels, using water evaporation to remove a significant amount of heat and lower the wheel temperature. However, this method requires frequent water refills, and many regions prohibit the unauthorized installation of water sprinkler systems on vehicles. The other method is to insulate the heat. Current wheel rim products often only consider load-bearing capacity, lightweight design, or compatibility with various vehicle tires, rarely incorporating heat insulation and cooling designs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to address the deficiencies of the existing technology by providing a vacuum-insulated truck and bus wheel rim, its processing method and application, thereby reducing the problem of rubber aging and tire blowout caused by long-term high temperature of the tire bead.

[0004] To solve this technical problem, the present invention provides a vacuum-insulated truck and bus wheel rim, comprising a rim flange, a bead seat, a groove bottom, a vacuum layer, wheel spokes, and an outer armor of the vacuum layer. A vacuum layer is provided at the rim flange, located below the bead seat and the groove bottom. The vacuum layer is an internal vacuum structure formed by tightly bonding the outer armor of the vacuum layer to the rim using vacuum welding technology. It can prevent the heat from the brake disc, axle, and wheel spokes from being transferred to the tire bead, allowing the heat from the tire bead to dissipate through the rim flange.

[0005] The spokes are provided with ventilation holes and screw holes, and the brake disc dissipates heat outward through the ventilation holes or to the sides.

[0006] The tire bead is mounted on the bead seat. During driving, the heat generated by the axle and brake disc is blocked by the vacuum layer, and the heat of the tire bead is dissipated through the rim flange.

[0007] The vacuum-insulated truck and bus wheel rims can be used for wheels with inner tubes and multi-piece rims, as well as for wheels with tubeless one-piece rims.

[0008] This invention also provides a processing method for the aforementioned vacuum-insulated truck and bus wheel rim. First, the A and B surfaces of the vacuum layer outer armor are processed. The B surface has a guide structure for the interlocking teeth. The A and B surfaces are interlocked together through the interlocking structure of the vacuum layer outer armor. Then, vacuum welding technology is used to tightly bond all gaps, forming an internal vacuum structure in the bead seat and the bottom of the groove. The evenly distributed pores of the interlocking teeth make the weld more uniform and dense. The outer edge of the vacuum layer outer armor and the outer edge of the wheel rim are horizontal. During vacuum welding, the edges are horizontally aligned to ensure welding accuracy and the dynamic balance performance of the wheel rim. Finally, the spokes are welded to the vacuum layer outer armor to complete the preparation of the vacuum-insulated truck and bus wheel rim product.

[0009] Beneficial effects: This invention utilizes the principle of vacuum insulation. Even when frequent braking causes a significant increase in the temperature of the brake disc and axle, the vacuum layer on the rim makes it difficult for the high temperature to be transferred to the tire bead, preventing high-temperature aging in that area. Furthermore, the original ventilation and heat dissipation holes on the rim allow the high temperature from the brake disc and axle to dissipate from both sides, with minimal transmission to the rim. Therefore, the cooling effect on the brake disc and axle is not significantly reduced. This invention reduces the conduction of high temperature to the rim bead seat, groove bottom, and tire bead, minimizing the problem of rubber aging and tire blowouts caused by prolonged high temperatures in the tire bead.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-6 As shown, the present invention provides a vacuum-insulated truck and bus wheel rim, comprising a rim 1, a bead seat 2, a groove bottom 3, a vacuum layer 4, wheel spokes 5, and a vacuum layer outer armor 13. A vacuum layer 4 is provided at the rim 1, located below the bead seat 2 and the groove bottom 3. The vacuum layer 4 is an internal vacuum structure formed by tightly bonding the vacuum layer outer armor 13 to the rim using vacuum welding technology. It can prevent the heat from the brake disc 9, axle 8, and wheel spokes 5 from being transferred to the tire bead 10. The absence of a vacuum layer on the left and right sides of the rim 1 allows the heat of the tire bead 10 to dissipate through the rim rim 1, thereby reducing the tire temperature and preventing the tire bead 10 from aging and causing damage and blowout due to excessive temperature.

[0020] The spokes 5 are provided with ventilation holes 6 and screw holes 7. The brake disc 9 dissipates heat outward through the ventilation holes 6 or dissipates heat to both sides.

[0021] The tire bead 10 is mounted on the bead seat 2. During driving, the heat generated by the axle 8 and brake disc 9 is blocked by the vacuum layer 4, and the heat of the tire bead 10 is dissipated through the rim flange 1.

[0022] The vacuum-insulated truck and bus wheel rims can be used for wheels with inner tubes and multi-piece rims, as well as for wheels with tubeless one-piece rims.

[0023] This invention also provides a processing method for the aforementioned vacuum-insulated truck and bus wheel rim. First, the A and B surfaces of the vacuum layer outer armor 13 are processed. The B surface has a meshing tooth guide structure 15. The A and B surfaces are meshed together by the meshing structure 14 of the vacuum layer outer armor. Then, the gaps are tightly joined together using vacuum welding technology, forming an internal vacuum structure in the bead seat and the bottom of the groove. The circumferentially distributed pores 16 of the meshing teeth make the weld more uniform and dense. The outer edge of the vacuum layer outer armor 13 and the outer edge of the wheel rim 1 are horizontal. During vacuum welding, the edges of the two are horizontally aligned to ensure welding accuracy and the dynamic balance performance of the wheel rim. Finally, the spokes 5 are welded to the vacuum layer outer armor 13 to complete the preparation of the vacuum-insulated truck and bus wheel rim product.

[0024] Its processing technology is as follows Figure 7 As shown: Original rim ① - Rim combined with vacuum layer outer armor ② - Spokes combined with rim with vacuum layer outer armor ③.

[0025] The vacuum-insulated wheel rim of this invention features a vacuum insulation layer, which reduces heat transfer from the brake disc and axle, lowering the temperature of the tire bead. The temperature of the tire bead seat and tire bead is significantly lower than that of the brake disc and axle, thus improving and reducing the problem of tire blowouts caused by long-term high-temperature aging due to overload and frequent braking. Ventilation holes are provided on the original wheel spokes, allowing heat from the brake disc and axle to dissipate through these holes and on both sides, preventing brake failure due to excessive heat. This also greatly reduces heat transfer to the rim bead seat, rim groove, and tire bead. This improves the problem of high-temperature tire blowouts caused by frequent braking in mining vehicles and dump trucks.

[0026] The above embodiments of the present invention are merely illustrative examples and are not the only ones. All modifications within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
