Technical Field

[0001] This utility model relates to the field of universal wheels, and in particular to a high-strength universal tire. Background Technology

[0002] A swivel caster, also known as a directional caster or universal wheel, is a special wheel design whose core feature is that the axle can rotate freely 360 degrees, allowing objects equipped with swivel casters to move flexibly in all directions without changing the object's orientation.

[0003] In the prior art, patent application CN202322634990.1 discloses a universal wheel, including a wheel and a connecting seat. The wheel and the connecting seat are rotatably connected. Two wheels are respectively arranged on opposite sides of the connecting seat. A locking tooth is provided on the side of the wheel closest to the connecting seat. The locking tooth is arranged in a ring. The connecting seat has a limiting groove, and a return spring and a connecting sliding tooth are provided in the limiting groove. The return spring is located between the connecting sliding tooth and the bottom of the limiting groove. The connecting sliding tooth slides within the limiting groove and engages with the locking tooth. The connecting sliding tooth has a foot block that abuts against it, and the foot block is rotatably connected to the connecting seat. This universal wheel, by setting a new braking method, can still maintain good braking function when bearing heavy objects. The meshing of the connecting sliding tooth and the locking tooth can ensure multi-angle locking. The structure is stable and can be used for a long time.

[0004] Existing omnidirectional tires have low support strength, are prone to deformation or breakage under long-term loads, have poor shock absorption when in contact with the ground, are prone to slipping, and wear out quickly. Therefore, it is necessary to improve this structure to overcome the above-mentioned defects. Utility Model Content

[0006] The above-mentioned technical objective of this utility model is achieved by the following technical solution:

[0007] A high-strength omnidirectional tire includes a support member and a rotating member. The support member is provided with a connecting unit and is connected to an external drive shaft through the connecting unit. The support member is made of a rigid material. The rotating member is located on the outside of the support member and its inner side is connected to the support member. The outer side of the rotating member is provided with a rolling contact surface. The rotating member is made of an elastic material.

[0008] A further feature of this invention is that the supporting member includes a supporting column and an annular bushing disposed on the supporting column. The inner side of the annular bushing is connected to the supporting column, and the outer side of the annular bushing is connected to the rotating member.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.

[0024] like Figures 1 to 3 As shown, this utility model proposes a high-strength omnidirectional tire, including a support member 10 and a rotating member 20. The support member 10 is provided with a connecting unit 30, and is connected to an external drive shaft (not shown) through the connecting unit 30. The support member 10 provides support and installation space and is made of a rigid material, improving the omnidirectional tire's resistance to pressure and deformation. The rotating member 20 is located on the outside of the support member 10, with its inner surface connected to the support member 10. The outer surface of the rotating member 20 has a rolling contact surface. The rotating member 20 is made of an elastic material, capable of absorbing impact, reducing vibration transmission, and lowering noise. In summary, the rigid support member 10 serves as a load-bearing component, while the elastic rotating member 20 provides a flexible contact surface, improving structural strength while ensuring smooth rolling of the omnidirectional wheel on the ground.

[0025] In some embodiments, the support member 10 includes a support column 11 and an annular bushing 12 disposed on the support column 11. The inner side of the annular bushing 12 is connected to the support column 11, and the outer side of the annular bushing 12 is connected to the rotating member 20. The annular bushing 12 serves as a transition structure to uniformly transfer the dynamic load of the rotating member 20 to the support column 11. There is a receiving space between the support column 11 and the annular bushing 12 for accommodating the connecting unit 30. Preferably, both the annular bushing 12 and the support column 11 are components supported by stainless steel, which significantly enhances the resistance to pressure and deformation, making it suitable for heavy-duty scenarios. The stainless steel material avoids rust, extends service life, and is suitable for humid environments.

[0026] In some embodiments, the rotating member 20 is provided with a positioning mounting hole 21, which extends through the axial direction of the rotating member 20. The rotating member 20 cooperates with the support member 10 through the positioning mounting hole 21. Preferably, the inner diameter of the positioning mounting hole 21 is slightly smaller than the outer diameter of the support member 10, and an interference fit is achieved by press fitting.

[0027] In some embodiments, multiple anti-slip patterns 22 are provided on the outer surface of the rotating component 20. In this embodiment, three anti-slip patterns 22 are provided. The anti-slip patterns 22 are annular anti-slip patterns. The anti-slip patterns 22 can improve the friction coefficient between the rotating component 20 and the ground, effectively prevent slipping, and the pattern structure can reduce the impact with the ground during rolling and reduce running noise. The bottom end of the anti-slip pattern 22 is connected to the rotating component 20, and the top end of the anti-slip pattern 22 extends outward from the rotating component 20. The anti-slip patterns 22 are distributed along the circumference of the rotating component 20. The shape of the anti-slip patterns 22 can be wavy or sawtooth. The number of anti-slip patterns 22 can be increased or decreased as needed. The number and shape in the figure are only for illustrative purposes.

[0028] In some embodiments, the connecting unit 30 includes a connecting bearing disposed within the accommodating space. One end of the connecting bearing is connected to the support column 11. The connecting bearing serves as a power transmission structure between the connecting unit and the external drive shaft, efficiently transmitting power to the rotating component 20.

[0029] In some embodiments, a limiting ring 13 is provided between the connecting bearing and the annular bushing 12. One end of the limiting ring is connected to the inner wall of the annular bushing 12, and the other end of the limiting ring 13 is connected to the outer wall of the connecting bearing. The limiting ring 13 restricts the axial movement of the bearing through the annular bushing 12 and the connecting bearing, avoids displacement deviation caused by vibration or impact, and improves transmission accuracy.

[0030] In some embodiments, the rotating member 20 and the supporting member 10 are interference-fitted. The rotating member 20 is a member supported by nylon material, which does not produce sharp noise when it collides hard with the ground.

[0031] The usage process of this utility model is as follows: In use, the tire support member 10 is connected to the external drive shaft through the connecting unit 30. The power of the external drive shaft is transmitted to the support column 11 through the connecting bearing, driving the rotating member 20 to rotate around the axis and move the equipment. The internal accommodating space of the support column 11 is used to fix the connecting bearing, and the axial displacement of the bearing is limited by the limiting ring to ensure stable power transmission. The rotating member 20 is press-fitted onto the outside of the annular bushing 12 of the support member 10 through an interference fit, and the size difference of the positioning mounting hole 21 is used to achieve a tight fit to prevent separation. When the tire bears a load, the rigid support member 10 evenly distributes the dynamic load to the support column 11 through the annular bushing 12, ensuring the compressive and deformation resistance under heavy load. When the elastic rotating member 20 contacts the ground, it absorbs the impact energy through material deformation, reducing the vibration transmitted to the equipment; at the same time, the anti-slip texture 22 on the outer surface increases friction and prevents slippage.
