Problems solved by technology

In order to further reduce the weight, it is necessary to increase the proportion of holes in the carcass, such as increasing the distribution density of the holes or increasing the volume of the holes, but both will weaken the strength of the carcass, especially after a period of use, the carcass is prone to softening , the amount of sinking gra

Embodiment Construction

[0042] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0043] See Figure 3 to Figure 9 As shown, the non-pneumatic tire disclosed in the present invention is made of rubber material, such as image 3 As shown, the vertical direction is defined as the tire radial direction, and the lateral direction is defined as the tire axial direction; Figure 5 As shown, CL stands for the center line of the tread, the left side of the tread center line CL is defined as the lower tire profile, and the right side of the tread center line CL is defined as the upper tire profile.

[0044] Such as image 3 As shown, the non-pneumatic tire includes a tread section 1, a middle section 2 and a bottom section 3. The tread section 1 is configured with a pattern and is in contact with the ground. The bottom section 3 is mounted on the rim. The upper end of the middle section 2 is connected to the tread section 1 and the lower end is connecte...

Abstract

The invention discloses a non-pneumatic tire. The non-pneumatic tire comprises a tread portion, a tire middle portion and a tire bottom portion. The upper end of the tire middle portion is connected to the tread portion, the lower end of the tire middle portion is connected to the tire bottom portion, the cross section of the tire middle portion is in a shape of H, the tire middle portion comprises an upper short horizontal part, a lower long horizontal part and a middle vertical part, the upper and lower ends of the middle vertical part are respectively connected to the upper short horizontalpart and the lower long horizontal part, two sides of the middle vertical part are inner concave surfaces and embedded blocks are arranged in the inner concave surfaces in two sides of the middle vertical part. The non-pneumatic tire reduces the weight of the tire, ensures riding comfort and stability of control and satisfies use requirements on light load and slow-rate bicycles and electric bicycles.

Description

Technical field [0001] The present invention relates to the technical field of rubber tires, in particular to non-pneumatic tires. Background technique [0002] Non-pneumatic rubber tires have the advantages of good wear resistance, safety and durability, but the solid structure makes the tires heavy and laborious to ride. In the prior art, most pneumatic tires are provided with a number of annular circumferential holes 20 (such as figure 1 As shown), or provide several rows of axial holes 40 in the sidewall 30 (such as figure 2 (Shown), through the provision of perforations in each part to reduce the use of rubber, and improve the tires, heavy and laborious riding problems. It has been confirmed that the perforation method can indeed reduce weight, and the perforated non-pneumatic tires are widely used in a variety of vehicles, including bicycles and electric bicycles. However, for bicycles and electric bicycles with small load capacity and low speed, because bicycles are only...
