However, when used on general roads or in other seasons, stud tires will produce greater noise and beating, which will affect riding comfort and increase rolling resistance
[0004] In view of the limitations of the use of winter tires above, and most ordinary consumers do not have the professional awareness of changing tires according to the weather and road conditions, the market needs a bicycle tire that can take into account the non-slip performance in winter and the comfort performance in summer, making it suitable for use in all seasons. resulting from

Embodiment approach
[0038] Such as Figure 1 to Figure 5 As shown, the present invention discloses a tread structure of a four-season bicycle pneumatic tire. exist figure 1 , the vertical direction is set as the tire radial direction, and the lateral direction is set as the tire axial direction; the tire 1 includes a tread portion 10 , a carcass layer 20 , side bead portions 30 and a pair of beads 40 .
[0039] Such as figure 2 As shown, the tread portion 10 of the tire 1 is formed by a plurality of pattern units arranged continuously, and each pattern unit includes two intersecting pattern main grooves 11, two symmetrically arranged pattern circular arc main grooves 12 and one pattern arc secondary groove 13, Pattern blocks are formed between the pattern grooves; the two pattern main grooves 11 are respectively symmetrical and arc-shaped extending downward from one side of the tread portion 10 to the other side of the tread portion 10; and the two pattern arc main grooves 12 are respectively ...
[0048] Vehicle used: install 28-inch city car front and rear wheels
[0049] Road conditions: winter roads, including dry asphalt roads and wet ice and snow roads.
[0050] Evaluation items: rolling resistance, grip performance, handling performance
[0051] Evaluation method: sensory evaluation by test drivers, 10-point method for evaluation, the larger the score, the better the performance.
[0052]
[0053] In summary, the present invention makes the overall tread pattern into a tortoise shell shape through the design of the main grooves 11, 12 and auxiliary grooves 13 on the tread portion 10 of the tire 1, forming an optimized land-to-sea ratio design, thereby improving tire grip and drainage performance. In addition, evenly distributed polygonal grooves 15 are arranged on the pattern blocks of the entire tread portion 10, and the grooves 15 are connected to each other and penetrate to the edges of the pattern bloc...

Abstract
The invention discloses a pattern structure of a bicycle pneumatic tire suitable for four seasons, which comprises a tire tread part and tire bead parts, wherein the tire bead parts are respectively located at both sides of the tire tread part; the tire tread part is formed by continuously arranging a plurality of pattern units; each pattern unit comprises two crossed pattern main channels, two symmetrically arranged pattern circular arc main channels and a pattern circular arc secondary channel; a pattern block is formed among all pattern grooves; the entirety of patterns on the tire tread part is in a turtle shell shape; and the whole pattern land-sea ratio is set to be 60-80 percent. The pattern block on the whole tire tread part is provided with polygonal grooves distributed evenly; the width of each polygonal groove is set to be 0.2mm-1.0mm; the depth of each polygonal groove is 1 / 4-1 / 2 of the depth of each pattern main channel; the grooves are mutually connected and penetrate through the edge of the pattern block; moreover, the tire bead part of the tire is provided with a plurality of rings of small pattern particles; the axial width is less than the radial length; and the small pattern particles are lower than 1.0mm. According to the pattern structure of the bicycle pneumatic tire suitable for the four seasons, the braking force of the bicycle pneumatic tire is effectively increased; the rolling resistance and the comfortability of the tire when running on common roads are not influenced; and a function that the bicycle pneumatic tire is suitable for use at four seasons is achieved.
Description
technical field [0001] The invention relates to a bicycle pneumatic tire, in particular to a four-season bicycle pneumatic tire pattern structure capable of improving the grip force of the tire on ice and snow roads. Background technique [0002] In many countries, traveling and going to work by bicycle has become a very common way of going out, which can not only exercise, but also save time. In recent years, with the increase of people's awareness of environmental protection, it is the general trend to choose to burn fat instead of gasoline. However, in northern my country or Europe, the whole winter is icy and snowy, and the roads are slippery. In addition, bicycles do not have anti-skid devices, and their own weight is lighter. [0003] For solving the difficulty that bicycle travels in winter, the industry has gradually appeared the tire of tread block inlaid with steel nails. The steel nails are evenly protruded on the tire tread, and the sharp nail edge can break th...
