A tire with a water storage hole
A water storage hole and tire technology, applied in tire parts, tire tread/tread pattern, vehicle parts, etc., can solve the problem of reducing the adhesion between the tire ground surface and the road surface, reducing the drainage efficiency of the tire tread, and reducing the tire tread. Adhesion to the ground and other issues, to reduce the possibility, ensure the water absorption and storage performance, and improve the drainage performance.

Problems solved by technology
[0003] On the one hand, the snow or ice on the road in winter will form a thin water film with a thickness of about 1-2mm on the snow or ice surface as the temperature rises, reducing the adhesion between the tire and the ground and causing slippage On the other hand, during the running of the vehicle, the tires generate heat due to rolling deformation, and the snow or ice adhered to the tire tread will melt into water, which reduces the drainage efficiency of the tire tread and the adhesion between the tire contact surface and the driving road surface. If the force is further reduced, the phenomenon of vehicle skidding will be aggravated, causing driving hazards

Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0034] see figure 1 , Figure 4 , Figure 5 and Figure 6 , the tire tread can be divided into many situations, it can be a rib-shaped tire tread with annular grooves, or a tire tread with transverse grooves; it can be an ordinary tire tread with less siping, or it can be a tire tread with Multi-siped winter tire tread. In order to improve the water drainage and anti-skid performance of tires with different tread types, by opening water storage holes 3 on ...

The invention discloses a tire with a water storage hole, the tire tread is provided with a main groove, and the tire ground surface is provided with more than one water storage hole; the upper part of the water storage hole cross-section is The tapered structure is narrow at the top and wide at the bottom, and the lower part of the section is an arc structure concave toward the center of the tire, and the lower end of the tapered structure transitions tangentially to the upper end of the arc structure. The present invention opens more than one water storage hole on the ground contact surface of the tire, so that the water on the driving road surface in contact with the ground contact surface of the tire can be temporarily stored in the water storage hole during the driving process of the vehicle, so as to ensure that the ground contact surface of the tire is in the running process. It can break the water film formed on the ground in time and improve the adhesion between the tire and the ground; at the same time, when the snow or ice attached to the tire tread melts into water, it can also be temporarily stored in the water storage hole, which improves the drainage of the tire. performance.
Description
technical field [0001] The invention relates to the technical field of tires, in particular to a tire with water storage holes. Background technique [0002] Due to the low temperature in winter, snowfall or rain will lead to snow accumulation and icing on the road, especially in the northern region of our country. In cold winter, snow accumulation and icing on the road are more common. When traveling in winter, when the vehicle is driving on snow-covered or icy roads, the adhesion between the tires and the road surface is reduced, and skidding is prone to occur. [0003] On the one hand, the snow or ice on the road in winter will form a thin water film with a thickness of about 1-2 mm on the snow or ice surface as the temperature rises, which will reduce the adhesion between the tire and the ground and cause slippage On the other hand, during the running of the vehicle, the tires generate heat due to rolling deformation, and the snow or ice adhered to the tire tread will m...
