Description

Tires with snow compaction and snow removal functions

The present invention relates to a tire structure that is suitable for driving on snow and has the functions of consolidating snow and discharging snow.

In order to improve the driving performance on special surfaces such as snow and mud, currently common tires are usually provided with recesses on the sidewalls to compress the snow and mud and increase the shear force to improve the traction effect. .

For example, there is the invention patent case No. CN104245360 "Pneumatic Tire" announced by mainland China on September 7, 2016. The raised step design on the tire shoulder surface in the previous patent effectively improves traction performance on snow and prevents the problem of tread cracks extending to the tire shoulder. However, it does not have the effect of compacting and solidifying snow, resulting in poor traction performance on snow.

There is also the invention patent case No. CN107107670 "Pneumatic Tire" announced by mainland China on June 14, 2019. The previous patent case utilizes the design of different widths of transverse grooves to consolidate slush and improve traction performance. However, there is a problem that the compacted slush cannot be discharged smoothly.

There is also the invention patent case No. CN108136853 "Pneumatic Tire" announced by mainland China on March 27, 2020. The patented tire shoulder has a stepped shape and multiple closed recesses. The recesses are used to compress the snow and sludge to increase shear force and improve traction performance. However, the shoulder step design will reduce the rigidity of the original shoulder part, and the snow sludge compacted in the concave part still has the problem of being unable to be discharged smoothly.

There is also the invention patent case No. CN111137070 "Tire" disclosed in mainland China on May 12, 2020. The previous patent discloses that the outer surface of the tire shoulder land portion has a groove surrounded by a convex portion. The groove is preferably formed continuously with the shoulder lateral groove. Such grooves can cooperate with the tire shoulder lateral grooves to exert large traction when entering uneven ground, thereby improving the traction performance of the tire when driving on uneven ground. However, the groove design only has the function of compacting the slush, but there is still a problem that the slush cannot be discharged smoothly, so it is not ideal in use.

The fourth length is greater than or equal to 2mm, and the third length is the length of the fifth side. is between 55% and 57% of the length of the fifth side, and the fourth length is between 14% and 17% of the length of the fifth side. A tire with snow compaction and snow discharge functions, including the tire with snow compaction and snow discharge functions described in any one of claims 1 to 8, is provided with a plurality of snow discharge grooves, and the snow discharge grooves are surrounded by Disposed on the shoulder of the second tire, the snow discharge groove is connected with the corresponding snow pressure groove. The bottom of the snow discharge groove has an inclined surface, and the depth of the snow discharge groove is directed from the tread portion to The sidewall portion is gradually deepened. The tire with functions of compacting and consolidating snow and discharging snow as described in claim 9, wherein a first short side of the snow discharging groove is connected with the snow compressing groove, and there is a concave and convex step difference at the connected position. , the snow discharge groove is provided with a second short side on the other side relative to the first short side, the length of the first short side is 1.56 times the length of the second short side, and the snow discharge groove is The length of a first long side is between 6.6 times and 10.5 times the length of the second short side, and the length of the snow discharge groove relative to a second long side on the other side of the first long side is The length of the second short side is between 4.6 times and 6 times, and an eighth included angle between the slope and a radial line radially perpendicular to the axis is between 14 degrees and 27 degrees.
