Description

Technical Field

[0001] The utility model relates to the technical field of rubber wheels, in particular to a high-compression heavy-duty rubber wheel. Background Art

[0002] For all kinds of vehicles moving in a rolling manner, most of them are equipped with circular tires to make their movement faster and more labor-saving. A rubber wheel is a common type of tire, and the outer ring in contact with the ground is made of rubber material.

[0003] In order to improve the anti-heavy-pressure ability of rubber wheels, support components are generally installed on the wheel hubs to prevent the wheel hubs from deforming. However, the installation of support components increases the weight of the tires, thereby increasing the fuel consumption of vehicle driving. Most traditional anti-compression tires cannot freely choose to disassemble and assemble the support components according to the actual situation. Therefore, in some cases with low loads, although the support components are not required to play a role, they still have to move together with the support components, thus increasing the fuel consumption. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a high-compression heavy-duty rubber wheel to facilitate solving the technical problems mentioned in the above background art.

A plurality of support plates are fixedly connected between the support inner ring and the support outer ring. A connecting member is arranged between the outer card slot and the corresponding inner card slot.

[0008] Furthermore, the connecting member includes an outer slideway opened on the outer peripheral surface of the support outer ring, an inner slideway is opened on the outer peripheral surface of the support inner ring. Slide bars are slidably connected in both the outer slideway and the inner slideway. Part of the slide bar is slidably inserted into the corresponding outer card slot or inner card slot. One side of the corresponding two slide bars close to each other is fixedly connected with a screw rod, and a screw sleeve is commonly threadedly connected to the outer peripheral surfaces of the corresponding two screw rods.

[0009] Further, the screw sleeve is arranged in a hexagonal prism shape.

[0010] Further, when the ends of two corresponding screws located inside the screw sleeve are in contact with each other, part of the sliding bar is located inside the outer slideway or the inner slideway.

Detailed implementation mode

[0021] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0022] Embodiment:

[0023] Referring to Figures 1 to 4 , a high-compression heavy-duty rubber wheel disclosed by the present utility model includes a tire body 100. The tire body 100 sequentially includes a fixed inner ring 101, a fixed outer ring 102, and a rubber tire body 103 from the inside to the outside. The outer peripheral side of the fixed outer ring 102 is fixedly connected to the rubber tire body 103. A plurality of fixing plates 104 are fixedly connected between the fixed inner ring 101 and the fixed outer ring 102. A plurality of outer card slots 2 are formed on the inner peripheral surface of the fixed outer ring 102, and a plurality of inner card slots 3 are formed on the outer peripheral surface of the fixed inner ring 101. A support part 4 is arranged between the fixed inner ring 101 and the fixed outer ring 102;

[0024] The support part 4 includes a support inner ring 41 and a support outer ring 42. The inner peripheral surface of the support inner ring 41 is in contact with the outer peripheral surface of the fixed inner ring 101, and the outer peripheral surface of the support outer ring 42 is in contact with the inner peripheral surface of the fixed outer ring 102. A plurality of support plates 43 are fixedly connected between the support inner ring 41 and the support outer ring 42. A connecting part 44 is arranged between the outer card slot 2 and the corresponding inner card slot 3.

[0025] In this embodiment, when the vehicle is in a low-load state, it can move only relying on the tire body 100, with low fuel consumption. When the driver judges that high-load driving is about to occur, the support part 4 is installed between the fixed inner ring 101 and the fixed outer ring 102. The support part 4 can improve the compressive resistance between the fixed outer ring 102 and the fixed inner ring 101 and prevent the tire from deforming.

[0026] When the fixed outer ring 102 is subjected to pressure, it is transmitted to the support plate 43 through the support outer ring 42 in contact with it, and then transmitted to the support inner ring 41 and the fixed inner ring 101, improving the radial anti-deformation ability of the fixed outer ring 102.

[0027] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 4As shown, the connecting member 44 includes an outer slideway 441 formed on the outer peripheral surface of the support outer ring 42, and an inner slideway 442 is formed on the outer peripheral surface of the support inner ring 41. Slide bars 443 are slidably connected in both the outer slideway 441 and the inner slideway 442. Part of the slide bar 443 is slidably inserted into the corresponding outer card slot 2 or inner card slot 3. On the side where the corresponding two slide bars 443 are close to each other, screw rods 444 are fixedly connected, and a screw sleeve 445 is commonly threadedly connected to the outer peripheral surfaces of the corresponding two screw rods 444.

[0028] In this embodiment, the slide bar 443 is arranged in a cuboid shape. When it is necessary to remove the support part 4, rotate the screw sleeve 445 to drive the corresponding two screw rods 444 to move. The screw rods 444 drive the slide bar 443 to move, so that the slide bar 443 disengages from the corresponding outer card slot 2 or inner card slot 3, and then pull the support part 4 outwards to pull out the support part 4.

[0029] When it is necessary to install the support part 4, insert the support part 4 between the fixed outer ring 102 and the fixed inner ring 101, and align the outer card slot 2 with the outer slideway 441. Then rotate the screw sleeve 445 to drive the slide bar 443 to insert into the outer card slot 2 or the inner card slot 3 to fix the support part 4.

[0030] In a further preferred embodiment of the present utility model, as Figure 1 shown, the screw sleeve 445 is arranged in a hexagonal prism shape.

[0031] In this embodiment, when the driver is inconvenient to manually rotate the screw sleeve 445, the screw sleeve 445 can be rotated by using a wrench to hold the screw sleeve 445.

[0032] In a further preferred embodiment of the present utility model, as Figure 1 shown, when the ends of the corresponding two screw rods 444 located inside the screw sleeve 445 are in contact with each other, part of the slide bar 443 is located inside the outer slideway 441 or the inner slideway 442.

[0033] In this embodiment, the cross-sectional dimension of the screw sleeve 445 is larger than the cross-sectional dimension of the slide bar 443. Therefore, the screw sleeve 445 cannot pass through the inner slideway 442 or the outer slideway 441. When the ends of the corresponding two screw rods 444 located inside the screw sleeve 445 are in contact with each other, that is, when the two slide bars 443 are closest to each other, the corresponding two slide bars 443 are still partially located inside the corresponding outer slideway 441 and inner slideway 442. Therefore, the connecting member 44 will not disengage between the support outer ring 42 and the support inner ring 41.

[0034] In a further preferred embodiment of the present utility model, as Figure 2 shown, a plurality of limiting grooves 5 are formed on the inner peripheral surface of the fixed outer ring 102, and a plurality of limiting blocks 6 are fixedly connected to the outer wall of the support outer ring 42. The limiting blocks 6 are slidably inserted into the corresponding limiting grooves 5.

[0035] In this embodiment, the side wall of the limiting block 6 fits against the inner wall of the corresponding limiting groove 5. When installing the supporting part 4, insert the limiting block 6 into its limiting groove 5, and then the outer card slot 2, the outer slideway 441, the inner slideway 442 and the inner card slot 3 can be aligned. There is no need to manually adjust the position of the supporting part 4 to align the outer card slot 2 and the outer slideway 441, which improves the installation efficiency of the supporting part 4.

[0036] The implementation principle of the above embodiment is as follows:

[0037] When the vehicle is in a low-load state, it can move only relying on the tire body 100, with low fuel consumption. When the driver judges that it is about to drive under high load, install the supporting part 4 between the fixed inner ring 101 and the fixed outer ring 102, insert the limiting block 6 into its limiting groove 5, and then rotate the screw sleeve 445 to drive the corresponding two screw rods 444 to move. The screw rods 444 drive the sliding strip 443 to move, so that the sliding strip 443 is inserted into the corresponding outer card slot 2 or inner card slot 3 to fix the supporting part 4. The supporting part 4 can improve the compressive capacity between the fixed outer ring 102 and the fixed inner ring 101 and avoid tire deformation.

[0038] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
