Description

Technical Field

[0001] The invention relates to the field of automobile tires, in particular to automobile tires that can be quickly repaired. Background Art

[0002] At present, pneumatic tires with inner tubes are widely used on automobiles. The principle is to inject compressed air into the inner cavity of the tire to make the tire bear the load. The biggest safety hazard is that once the tire is punctured or scratched by a sharp object, it is very easy to leak air or even blow out. If a tire blows out while the car is driving at high speed, the direction of the car will be out of control, which can easily cause a safety accident.

[0003] After a traditional pneumatic tire bursts, it is necessary to replace it with a spare tire. However, when replacing the spare tire, the tire needs to be removed. It is difficult for one person to replace the spare tire, the replacement process is cumbersome, and the replacement time is long. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to propose a car tire that can be quickly repaired, so as to solve the problem that when replacing the spare tire with the existing pneumatic tire, the tire needs to be disassembled, the replacement is difficult, the replacement process is cumbersome, and the replacement time is long.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: comprising a wheel hub, a connecting assembly connected to a vehicle transmission shaft is provided at the center of the wheel hub, fixing blocks evenly distributed along the circumference are provided on the outer arc surface of the wheel hub, and gaps are left between adjacent fixing blocks, the upper surface of the fixing block is a slope surface, a fixing groove is provided on the slope surface, a pad is provided in the fixing groove and is installed obliquely toward the upper end of the slope surface, the fixing block is provided with a first threaded hole on the surface away from the vehicle body, an arc-shaped elastic steel sheet is provided above the fixing block, and both ends of the arc-shaped elastic steel sheet are divided into A first bending portion and a second bending portion are separately provided, and hooks distributed side by side are provided in the middle of the arc-shaped elastic steel sheet, and the hooks are provided on the surface of the arc-shaped elastic steel sheet that is consistent with the forward direction of the automobile, and a connecting portion corresponding to the first threaded hole is provided on the bottom side of the arc-shaped elastic steel sheet, the first bending portion is located in the gap, and the second bending portion is hung with the hook, and the connecting portion and the first threaded hole are fixedly connected by bolts, and the outer sides of the arc-shaped elastic steel sheets are coated with injection-molded anti-wear pads, and the anti-wear pads are in close contact with the top ends of each arc-shaped elastic steel sheet.

[0006] Furthermore, a circular sealing cover is provided outwardly at the edge of the outer side surface of the wheel hub, and the outer side surface of the circular sealing cover is provided with evenly distributed fixing through holes along the circumferential direction, and the side surface of the fixing block is provided with a second threaded hole matching the fixing through holes on the circular sealing cover, and the circular sealing cover and the fixing block are fixedly connected by bolts. The advantage is that the circular sealing cover and the fixing block are fixedly connected by bolts, which is faster during installation and disassembly, and the circular sealing cover covers the fixing block, making the side appearance of the tire more visually integrated.

[0007] Furthermore, the connection portion on the arc-shaped elastic steel sheet is located within the sealing area of ​​the circular sealing cover. The benefit is that the circular sealing cover protects the connection portion of the arc-shaped elastic steel sheet therein, which not only improves the overall appearance of the tire, but also protects the bolts and threaded holes on the connection portion, preventing mud and sand from entering the thread gap or the threaded hole, making it difficult to remove and install the bolts in the threaded hole.

[0008] Furthermore, the anti-wear pad is made of wear-resistant rubber, and the surface of the anti-wear pad is provided with anti-skid patterns to prevent the tire from slipping. The anti-skid patterns include horizontal patterns and vertical patterns. The advantage is that the friction between the tire and the ground is relatively large. The reason for selecting rubber is that rubber is not only wear-resistant and can extend the life of the anti-wear pad, but the anti-skid patterns can increase the friction between the tire and the ground, making it less likely for the tire to slip, making driving safer.

[0009] Furthermore, the fixing groove includes an inclined groove arranged in the upper middle part of the slope surface and a clamping groove at the bottom of the slope surface. The inclined groove and the clamping groove are vertically arranged. The advantage is that the cushion block is installed in the inclined groove and the clamping groove, so that the installation of the cushion block does not take up space, and the gasket is installed inside the fixed block more firmly.

[0010] Furthermore, the thickness of the upper end of the anti-wear pad is greater than that of the lower end thereof, which is beneficial in that the end of the tire in contact with the ground is more worn, and increasing the thickness can extend its service life and also achieve a shock-absorbing effect.

[0011] Furthermore, a third bending portion is provided at one end of the cushion block, and a fourth bending portion is provided at the other end of the cushion block. The third bending portion is clamped with the clamping slot of the fixing slot, and after clamping, the curvature of the upper surface of the cushion block is consistent with the curvature of the slope surface. The advantage is that the cushion block is clamped in the clamping slot, making its installation stable and not easy to fall out, and after installation, the curvature is consistent with the slope surface, which facilitates the installation of the arc-shaped elastic steel sheet above the fixing block.

[0012] Furthermore, the pad is located below the arc-shaped elastic steel sheet fixed on the same fixed block, and the pad and the arc-shaped elastic steel sheet are in close contact. The fourth bent portion of the pad is located outside the top of the slope surface, and the length of the fourth bent portion is 1.5-2 times the width of the gap formed between adjacent fixed blocks. The benefit is that when the arc-shaped elastic steel sheet bounces greatly during driving of the car, the fourth bent portion can limit the up and down movement of the arc-shaped elastic steel sheet to prevent the first bent portion from escaping from the gap and affecting the normal use of the tire. The pad is located at the lower part of the arc-shaped elastic steel sheet and is squeezed between the fixed block and the arc-shaped elastic steel sheet, making it more securely fixed.

[0013] The advantage of adopting the above technical solution is that the outer ring of the tire is made of arc-shaped elastic steel sheets with wear-resistant rubber coated on the outer periphery, and when one of the sheets is damaged, there is no need to disassemble the car tire. You only need to remove the circular sealing cover, loosen the bolts on the connecting part of the damaged arc-shaped elastic steel sheet, remove the damaged arc-shaped elastic steel sheet, replace it with a new arc-shaped elastic steel sheet, tighten the bolts on the connecting part, and then install the circular sealing cover. When the tire in this technical solution is damaged, there is no need to replace the spare tire, only the arc-shaped elastic steel sheet at the damaged position needs to be replaced. Replacing the arc-shaped elastic steel sheet is easy, the operation is simple, and the time required for replacement is short, which can effectively improve the repair efficiency of the damaged tire to a certain extent.

[0017] The following is further described in detail through specific implementation methods:

[0018] The figure marks in the drawings of the specification include: wheel hub 1, circular sealing cover 2, anti-wear pad 3, connecting assembly 4, fixing through hole 5, fixing block 6, pad 7, arc-shaped elastic steel sheet 8, first bending portion 9, third bending portion 10, hook 11, connecting portion 12, second threaded hole 13, first threaded hole 14, second bending portion 15, fourth bending portion 16, fixing groove 17.

[0019] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The specific implementation process is as follows:

[0021] like Figures 1 to 3 As shown, the automobile tire that can be quickly repaired has a hub 1 in common with a conventional automobile tire. A connecting assembly 4 fixedly connected to an automobile output shaft is provided at the center of the hub 1. A fixing block 6 is provided inside the outer ring of the hub 1. The fixing blocks 6 are evenly arranged along the circumferential direction of the outer ring of the hub 1, and there are gaps between adjacent fixing blocks 6. When the automobile hub 1 is produced, the fixing blocks 6 and the automobile hub 1 are integrally formed. The fixing block 6 is in the shape of a rectangle with a sloped surface on the upper portion. The height of the sloped surface for normal driving and reverse driving of the automobile tire is relatively low. A fixing groove 17 is provided on the sloped surface in the middle of the fixing block 6. The fixing groove 17 is divided into an upper sloped groove and a lower card groove vertically arranged similar to the sloped groove.

[0022] A cushion block 7 is clamped in the fixing groove 17 of the fixing block 6, the middle part of the cushion block 7 is an arc-shaped surface matching the curvature of the inclined groove, and a third bending portion 10 is provided at one end of the cushion block 7, and a fourth bending portion 16 is provided at the other end. The third bending portion 10 is clamped in the clamping groove of the fixing groove 17, the fourth bending portion 16 is located on the outside of the top of the slope surface of the cushion block 7, and the thickness of the middle part of the cushion block 7 is consistent with the part removed in the inclined groove, the fourth bending portion 16 is above the gap formed by adjacent fixing blocks 6, and preferably, the length of the fourth bending portion 16 is 1.5 times the gap.

[0023] In the same fixed block 6, an arc-shaped elastic steel sheet 8 is provided above the pad 7. The middle part of the arc-shaped elastic steel sheet 8 is "S"-shaped. When installed, the protruding surface of the "S" shape is located at the uppermost end of the tire. A first bending portion 9 and a second bending portion 15 are provided at both ends thereof, respectively. The first bending portion 9 is located in the gap formed between adjacent fixed blocks 6. A hook 11 is provided in the middle part of the arc-shaped elastic steel sheet 8. The hook 11 is provided on the surface in the forward direction of the automobile tire. The second bending portions 15 and the hook 11 of two adjacent fixed elastic steel sheets are connected. The advantage of such a setting is that when the tire is in contact with the ground and subjected to force, force conduction can be achieved between the elastic steel sheets, and multiple arc-shaped elastic steel sheets 8 are subjected to force together, so that the force on a single arc-shaped elastic steel sheet 8 is reduced, thereby ensuring its service life.

[0024] On the side away from the car body, a first threaded hole 14 is opened on the side of the fixing block 6 for fixing the arc-shaped elastic steel sheet 8, and a connecting portion 12 is provided on the arc-shaped elastic steel sheet 8 at a position corresponding to the first threaded hole 14, and the connecting portion 12 and the first threaded hole 14 are fixedly connected by bolts. Since the length of the fourth bent portion 16 is greater than the gap between adjacent fixing blocks 6, the fourth bent portion 16 is above the bottom of its adjacent arc-shaped elastic steel sheet 8, which is beneficial in that when the arc-shaped elastic steel sheet 8 jumps greatly during driving of the car, the fourth bent portion 16 can limit the up and down movement of the arc-shaped elastic steel sheet 8 to prevent the first bent portion 9 from escaping from the gap and affecting the normal use of the tire, and the pad 7 is located at the lower part of the arc-shaped elastic steel sheet 8 and is squeezed between the fixing block 6 and the arc-shaped elastic steel sheet 8, making it more securely fixed.

[0025] The outer side of the arc-shaped elastic steel sheet 8 is coated with an anti-wear pad 3, and the material of the anti-wear pad 3 is wear-resistant rubber. The wear-resistant rubber and the arc-shaped elastic steel sheet 8 are injection molded, and the gap between the arc-shaped elastic steel sheet 8 and the fixed block 6 or the clamping connection between the hooks 11 are all clearance fit. The wear-resistant rubber layer on the upper end of the arc-shaped elastic steel sheet 8 is thicker because it is in contact with the bottom surface. A thicker layer is not only more wear-resistant but also has a shock-absorbing effect. Each arc-shaped elastic steel sheet 8 coated with the anti-wear pad 3 is tightly matched at the outermost side, with a smooth transition to form a circle, and anti-slip patterns including horizontal and vertical lines are provided on the anti-wear pad 3 to prevent the car tire from slipping.

[0026] Preferably, a circular sealing cover 2 is provided on the outer edge of the hub 1, and the circular sealing cover 2 shields the connection portion 12 of the arc-shaped elastic steel sheet 8 to prevent mud and sand from entering between the thread pitches or into the threaded holes, making it inconvenient to install and remove the bolts. The circular sealing cover 2 is provided with a plurality of fixing through holes 5, and the circular sealing cover 2 is fixed to a plurality of second threaded holes 13 opened in the fixing block 6 by bolts. Preferably, two groups of second threaded holes 13 for facilitating the fixing of the circular sealing cover 2 are opened on the fixing block.

[0027] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
