Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a tread groove of a funnel tire. Background Art

[0002] When a vehicle is driving on a rainy day, if the accumulated water between the tire and the road surface cannot be discharged in time, a layer of water film will be formed between the tire and the ground. The water film prevents the tire from fitting properly with the ground, greatly reducing the various performances of the tire such as handling, grip, braking, etc. We call this phenomenon hydroplaning. Hydroplaning is actually very common. It will occur as long as it is on a slippery road. Its severity is proportional to the speed of the vehicle. Tires with strong wetland performance basically have four longitudinal main grooves, which greatly improve the drainage capacity of the tire, and the transverse patterns on both sides can effectively prevent the formation of water film, which minimizes the probability of hydroplaning. The existing technology mainly breaks the water film to improve wetland performance by increasing the width of the longitudinal grooves and the transverse grooves of the tire. This groove design improves wetland performance while also reducing the ground contact area between the tire and the ground, affecting dry braking performance, and failing to meet the requirements of balancing dry and wet performance. Based on this, a funnel tire tread groove is now provided to eliminate the drawbacks of the existing device. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

When there is a lot of water on the road, the funnel diameter 5 cooperates with the longitudinal groove 1 to quickly discharge the water, thereby improving the wet braking performance of the tire.

[0030] In one embodiment, Figure 1and Figure 4 As shown, the funnel diameter 5 is longitudinally connected to the cylindrical transverse groove 7 through the longitudinal fine groove 6, the cylindrical transverse groove 7 is connected to the longitudinal pattern groove 1, the width n of the longitudinal fine groove 6 is 0.4mm-2.0mm, the height h3 of the longitudinal fine groove 6 is 1 / 5GD-1 / 4GD, the radius r of the cylindrical transverse groove 7 is 0.8mm-3.2mm, and the longitudinal fine groove 6 and the cylindrical transverse groove 7 are interconnected, which can quickly drain away the tread surface water.
