Description

Technical Field

[0001] The invention relates to the field of lightweight design of air-free tires, and in particular to an internal support device of a lightweight and highly shock-absorbing air-free tire. Background Art

[0002] Airless tires are tires that do not need to be inflated. They do not rely on air, but only use the tire's own materials and structure to achieve support and cushioning performance. ① Rubber solid tires. This type of tire has a production history of hundreds of years. The main characteristics are heavy tire body, poor elasticity, large rolling resistance, and large load-bearing capacity. It is suitable for vehicles with slow movement speed and relatively large load requirements. ② Open structure tires. It uses polyurethane material as raw material, and is made of open structure and tube-type staggered three-dimensional shock absorption. The advantages are beautiful appearance and light weight, and the disadvantages are low-speed driving and not resistant to high temperatures.

[0003] In order to further increase the supporting force of the airless tire, most of them are reinforced by adding steel bars and other components inside the airless tire. However, this will undoubtedly increase the overall weight of the tire, which is not in line with the lightweight design. Some tires are hollowed out. Although lightweight is achieved, the overall strength will decrease accordingly, making it difficult to control the tire supporting force during the operation of the wheel. Therefore, it is urgently necessary to design a lightweight and highly shock-absorbing internal support device for airless tires to solve the shortcomings of the prior art. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art and to provide a lightweight and highly shock-absorbing internal support device for an air-free tire.

[0005] The objective of the present invention is achieved through the following technical scheme: a lightweight and highly shock-absorbing internal support device for an airless tire, comprising an airless tire and a rotating shaft, the surface of the rotating shaft is sleeved with a connecting ring, a wheel frame is evenly welded on the lower side of the connecting ring, a second guide wheel is mounted on the lower end of the wheel frame, a pull rod is fixedly installed on the middle part of the upper surface of the connecting ring, a mounting plate is fixedly installed on the top of the pull rod, screws are mounted on the mounting plate, a filling layer is evenly sleeved inside the airless tire, a cavity is provided between the filling layers, an air cylinder is evenly installed on the inner side of the airless tire, a vent hole communicating with the cavity is provided at the inner end of the air cylinder, a sliding rod is sleeved inside the air cylinder, a piston is provided on one end of the sliding rod extending into the air cylinder, a first guide wheel is mounted on the other end of the sliding rod, a baffle is installed on the surface of the sliding rod, a coil spring is connected between the baffle and the air cylinder.

[0006] As a preferred technical solution of the present invention, the filling layer is made of rubber blocks.

[0007] As a preferred technical solution of the present invention, the inner end surface of the airless tire is provided with a hole corresponding to the vent hole.

[0008] As a preferred technical solution of the present invention, the piston is slidably matched with the air cylinder, and the piston is made of rubber material.

[0009] As a preferred technical solution of the present invention, the sliding rod is slidably matched with the gas cylinder.

[0010] As a preferred technical solution of the present invention, the baffle plate is threadedly matched with the slide rod, and the coil spring is fixedly connected to the baffle plate and the air cylinder respectively.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention arranges a plurality of wheel frames, and when the wheel is running, the cavity part that is about to contact the ground can be filled with materials in advance, so as to further increase the supporting force of the tire, improve the shock absorption effect, and prevent the phenomenon of pressing the tire in the cavity state. The inside of the tire can be controlled during the rotation of the wheel, and the material can be repeatedly filled and discharged, so that the weight of the tire can be reduced during the rotation of the wheel without losing the supporting force of the tire. The device can be quickly installed through screws, and the elastic force of the spiral spring can be conveniently controlled through the threaded cooperation of the baffle and the slide rod, so that the first rotating wheel and the second rotating wheel are more closely fitted, and the control of the filling and discharging of materials in the air cylinder is realized. The present invention repeatedly fills and discharges materials in the cavity of the airless tire, so as to facilitate the control of the supporting force of the tire, and also conforms to the lightweight design and is relatively convenient to operate.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-2 , the present invention provides a technical solution:

[0018] A lightweight and highly shock-absorbing internal support device for an air-free tire comprises an air-free tire 3 and a rotating shaft 14, wherein a connecting ring 15 is sleeved on the surface of the rotating shaft 14, a wheel frame 16 is uniformly welded on the lower side of the connecting ring 15, a second guide wheel 17 is mounted on the lower end of the wheel frame 16, a pull rod 9 is fixedly mounted on the middle part of the upper surface of the connecting ring 15, a mounting plate 7 is fixedly mounted on the top of the pull rod 9, a screw 8 is mounted on the mounting plate 7, a filling layer 1 is uniformly sleeved on the inside of the air-free tire 3, a cavity 2 is arranged between the filling layers 1, an air cylinder 5 is uniformly mounted on the inner side of the air-free tire 3, a vent 4 communicating with the cavity 2 is arranged on the inner end of the air cylinder 5, a sliding rod 10 is sleeved on the inside of the air cylinder 5, a piston 6 is mounted on one end of the sliding rod 10 extending into the air cylinder 5, a first guide wheel 13 is mounted on the other end of the sliding rod 10, a baffle 12 is mounted on the surface of the sliding rod 10, a coil spring 11 is connected between the baffle 12 and the air cylinder 5.

[0019] The filling layer 1 is made of rubber blocks.

[0020] The inner end surface of the airless tire 3 is provided with a hole corresponding to the vent hole 4 .

[0021] The piston 6 is slidably matched with the air cylinder 5, and the piston 6 is made of rubber material.

[0022] The slide bar 10 is in sliding cooperation with the gas cylinder 5 .

[0023] The baffle plate 12 is threadably matched with the slide rod 10 , and the coil spring 11 is fixedly connected to the baffle plate 12 and the air cylinder 5 , respectively.

[0024] Working principle: In order to increase the supporting force inside the airless tire 3, during the specific operation, first put the connecting ring 15 on the rotating shaft 14 of the vehicle, and then fix the mounting plate 7 to the bottom of the vehicle by screws 8. The air cylinder 5 is provided with an inlet and outlet, and foam balls are filled in the air cylinder 5. Then the airless tire 3 is put on the wheel hub so that the air cylinder 5 is on both sides of the wheel hub. The preparation work is completed. When the vehicle is driving, it will drive the airless tire 3 to rotate, and the first guide wheel 13 at the bottom will be pushed by the second guide wheel 17, so that the slide rod 10 slides into the air cylinder 5, and the sliding combination of the piston 6 and the air cylinder 5 is used. The piston 6 is closed by the air cylinder 5, thereby filling the cavity 2 with the material in the air cylinder 5, thereby filling the cavity 2. At this time, the gas generated when the piston 6 and the air cylinder 5 slide is filled in the cavity 2, further increasing the supporting force of the tire. As the tire rotates, the second guide wheel 17 stops squeezing the first guide wheel 13, thereby pulling the piston 6 outward through the elastic force of the coil spring 11, and quickly drawing the material in the cavity 2 into the air cylinder 5, so that the cavity 2 in the air-free tire 3 that does not touch the ground is not filled with material, so that the overall lightweight design of the air-free tire 3 makes the tire more durable.
