Description

Technical Field

[0001] The utility model relates to the technical field of wheels, in particular to a tire pattern and a wheel. Background Art

[0002] As an important mechanical component, wheels can effectively reduce the contact area with the ground, thereby reducing friction and making objects easier to move.

[0003] Tire friction plays a crucial role in vehicle driving. The friction between the tires and the ground provides the grip necessary for the vehicle to move, which is the basis for vehicle movement. When friction is insufficient, the vehicle is prone to slipping, resulting in loss of control, and the vehicle's handling is also affected.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Utility Model Content

[0005] In view of the above shortcomings of the prior art, the purpose of the present invention is to provide a tire pattern and a wheel to improve the friction of the tire.

[0006] The technical solution of the utility model is as follows:

[0007] A tire pattern and a wheel include: an annular hub; a tire body, wherein the annular tire body is circumferentially sleeved on the outer diameter of the annular hub; wherein a first groove is provided on the tread of the tire body, and the first groove is circumferentially arranged around the axis of the tire body; a second groove is provided on the tread of the tire body, and the second groove is arranged along the axial direction of the tire body, and one end of the length of the second groove is connected to the sidewall of the tire body; along the axial direction of the tire body, the second grooves connecting different sidewalls are staggered.

[0008] A further technical solution is that the cross section of the annular hub is I-shaped.

[0009] A further technical solution is that reinforcing ribs are provided on the annular hub along the axial direction of the carcass.

[0010] A further technical solution is that an inner ring is provided within the inner diameter of the annular hub, and an inner gear ring is provided on the inner diameter of the inner ring.

[0011] A further technical solution is that the inner diameter of the annular hub extends toward one side of the axis of the carcass to form a first step, and one end of the inner ring width contacts the side surface of the first step.

[0012] A further technical solution is that screw holes and positioning holes are opened on the annular hub along the axial direction of the tire body, and the screw holes and the positioning holes pass through the annular hub and penetrate into the inner ring.

[0013] A further technical solution is that a bearing is further provided in the inner ring, the inner diameter of the inner ring extends toward one side of the axis of the carcass to form a second step, and one end of the bearing contacts the side surface of the second step.

[0014] A further technical solution is that two bearings are provided, and the two bearings are arranged side by side and in parallel along the axis of the carcass.

[0015] A further technical solution is that an annular groove is opened at the inner diameter of the inner ring around the axis of the carcass, a support block is arranged in the annular groove, the support block supports an annular retaining ring, and the annular retaining ring is arranged between the two bearings.

[0016] A further technical solution is that the side surface of the first step exceeds the outer diameter of the bearing.

[0017] The beneficial technical effects of the utility model are as follows:

[0018] (1) The tire pattern and wheel in the utility model are provided with a first groove on the tread of the tire body, and the first groove is circumferentially arranged around the axis of the tire body. The sidewall of the first groove of the tread deformation can contact the ground, and uneven ground can also be partially sunken into the first groove.

In addition, a second groove is provided on the tread of the tire body, and the second groove is arranged along the axis of the tire body. The sidewall of the second groove of the tread deformation can contact the ground, and uneven ground can also be partially sunken into the second groove. During the rolling of the tire along the ground, the second groove can enhance the friction between the tire and the ground in the front and back directions.

[0019] (2) Furthermore, one end of the second groove is connected to the sidewall of the tire body, thereby enhancing the deformation capacity of the tire body. Under load-bearing conditions, the tread deformation increases, the contact area between the tread and the ground increases, and thus the friction between the tire and the ground is increased, thereby enhancing the tire's grip.

[0020] (3) Furthermore, the second grooves connecting different sidewalls are staggered so that when the tread rotates at a full angle, there are always second grooves on the left and right sides of the tread in contact with the ground, thereby ensuring friction between the tire and the ground.

[0027] Figure 1 A schematic diagram of the three-dimensional structure of the tire pattern and wheel of the present invention is shown. Figure 2 The cross-sectional structure diagram of the tire pattern and wheel of the present invention is shown. Figure 1 and Figure 2, a tire pattern and a wheel, comprising an annular hub 2 and a carcass 1. The annular carcass 1 is circumferentially sleeved on the outer diameter of the annular hub 2. Particularly, a first groove 11 is provided on the tread of the carcass 1, and the first groove 11 is circumferentially arranged around the axis of the carcass 1. The sidewalls of the first tread deformation groove 11 can contact the ground, and uneven ground can also be partially sunken into the first groove 11. During the rolling of the tire along the ground, the first groove 11 can enhance the friction between the tire and the ground in the left and right directions. A second groove 12 is provided on the tread of the carcass 1, and the second groove 12 is arranged along the axial direction of the carcass 1. The sidewalls of the second tread deformation groove 12 can contact the ground, and uneven ground can also be partially sunken into the second groove 12. During the rolling of the tire along the ground, the second groove 12 can enhance the friction between the tire and the ground in the front and rear directions.

[0028] Preferably, one end of the second groove 12 is connected to the sidewall of the tire body 1. This enhances the deformation capacity of the tire body 1. Under load, the tread deformation increases, and the contact area between the tread and the ground increases, thereby increasing the friction between the tire and the ground and enhancing the tire's grip.

[0029] More preferably, the second grooves 12 connecting different sidewalls are staggered along the axial direction of the carcass 1 so that when the tread rotates at full angles, there is always a second groove 12 on the left and right sides of the tread in contact with the ground, ensuring friction between the tire and the ground.

[0030] Please refer to Figure 2 The annular hub 2 has an I-shaped cross-section. The I-beam's cross-sectional design provides the annular hub 2 with high strength when subjected to tension and compression, effectively supporting the vehicle. Furthermore, the I-beam's generous clearance reduces the weight of the annular hub 2.

[0031] Furthermore, along the axial direction of the carcass 1, the annular hub 2 is provided with reinforcing ribs 21. The reinforcing ribs 21 enhance the structural strength of the annular hub 2, so that the annular hub 2 has good stability during use and is not easily deformed.

[0032] Please refer to Figure 2 The inner diameter of the annular hub 2 is further provided with an inner ring 3, and the inner diameter of the inner ring 3 is provided with an inner gear ring 32. The driving device transmits torque to the wheel by engaging the inner gear ring 32.

[0033] In this embodiment, the inner radial direction of the annular hub 2 extends toward the axis of the carcass 1 to form a first step 22. One end of the width of the inner ring 3 contacts the side of the first step 22. A bearing 7 is also disposed within the inner ring 3. A second step 31 extends from the inner radial direction of the inner ring 3 toward the axis of the carcass 1 to form a second step 31. One end of the bearing 7 contacts the side of the second step 31. The side of the first step 22 extends beyond the outer diameter of the bearing 7. The first step 22 and the second step 31 cooperate to secure the position of the bearing 7.

[0034] Please refer to Figure 1 and Figure 2 Along the axis of the carcass 1, the annular hub 2 is provided with screw holes 8 and positioning holes 9. These holes penetrate the annular hub 2 and extend into the inner ring 3. By inserting a positioning pin into the positioning hole 9, the relative position between the annular hub 2 and the inner ring 3 can be quickly determined, speeding up assembly. Furthermore, screws inserted into the screw holes 8 secure the position of the annular hub 2 and the inner ring 3 within the bracket. This screw connection method is simple, inexpensive, and easy to disassemble.

[0035] Preferably, two bearings 7 are provided, and the two bearings 7 are arranged parallel to each other along the axis of the carcass 1. The two bearings 7 can effectively disperse the load applied to the shaft, reduce the burden of a single bearing 7, and thus improve the load-bearing capacity and service life of the entire system.

[0036] More preferably, an annular groove 4 is formed at the inner diameter of the inner ring 3 around the axis of the carcass 1, a support block 5 is provided in the annular groove 4, and the support block 5 supports an annular retaining ring 6, which is provided between two bearings 7. The retaining ring 6 fixes and maintains the bearing 7 in its working position by the bearing 7, preventing the bearing 7 from axial or radial displacement during operation.

[0037] Further preferably, the side surface of the first step 22 exceeds the outer diameter of the bearing 7 , and the axial displacement of the bearing 7 is further limited by the first step 22 .

[0038] The specific workflow of this utility model is as follows:

[0039] The drive unit transmits torque to the wheel by meshing with the internal gear ring 32, driving the annular hub 2 and tire carcass 1 to rotate about their respective axes, thereby moving the vehicle on which the wheel is mounted. During vehicle movement, the tread is compressed, causing portions of the sidewalls of the first grooves 11 to contact the ground, allowing any uneven ground to partially sink into the first grooves 11, enhancing the wheel's grip in the left-right direction. Simultaneously, this compression causes portions of the sidewalls of the second grooves 12 to contact the ground, allowing any uneven ground to partially sink into the second grooves 12, enhancing the wheel's grip in the fore-and-aft direction.

[0040] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
