Performance-balanced strong wet grabbing tire pattern

Abstract

The invention belongs to the technical field of tires, and particularly relates to a performance-balanced strong wet grabbing tire pattern which comprises a longitudinal main groove and an inner middle pattern block, the inner middle pattern block is provided with a plurality of cutter grooves, the cutter grooves are transversely arranged and are inclined at a certain angle, and the angle range is 45-75 degrees; at least one end of the cutter grooves is connected with the longitudinal main groove; a tubular channel is arranged at the bottom of the cutter grooves; at least one end of the tubular channel is communicated with the longitudinal main groove; and a radial pipeline is also arranged in the cutter grooves and is connected with the tubular channel and the surface of the inner middle pattern block. The problems that in the prior art, the wet slippery performance is improved only from the angle of drainage, and the improvement effect is low are solved, the water storage volume is increased through multiple design schemes, the drainage speed is increased, the water film cutting capacity is improved, and the wet slippery performance of the tire is greatly improved; besides, the groove depth does not need to be increased in the pattern design, the control stability, rolling resistance, noise, abrasion and the like are fully considered, and the tire performance can be more balanced.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a strong wet-grip tire pattern with balanced performance. Background technique [0002] The wet performance of tires is an important indicator affecting the safety performance of vehicles, and it is an item that is focused on by laws, regulations and end users. Since the performance of tires is very complex, how to effectively improve the wet skid performance of tires without affecting other performances is a key and difficult issue in the automotive tire industry. [0003] In wet and slippery conditions, due to the presence of water on the road surface, the tires cannot effectively contact the road surface, thereby reducing the gripping ability of the tires. Therefore, it is necessary to focus on improving the wet skid performance and improving the drainage capacity of the pattern. Usually the tire pattern is composed of longitudinal main groove and transverse groove....

AI Technical Summary

Problems solved by technology

However, this patented method only considers the enhancement of drainage capacity, but does not consider the ability to grip the ground. In addition, the flow pipe is a longitudinal pipe. When the vehicle is running, the contact time between the horizontal groove and the road surface is very short, and the water that can flow upward into the pipe is very limited. The effectiveness of improving wet skid performance is not high

[0007] When improving the tire wet skid problem from the aspect of tire tread design, it is usually only improved from the perspective of improving drainage performance. The improvement idea is relatively single, the consideration is not comprehensive enough, and the effectiveness of improving wet skid performance is low.

In addition, there are many other tire performances that need to be paid attention to at the same time, such as dry ground, rolling resistance, noise, wear, etc. Many performance requirements for design are contradictory. When using conventional methods to improve wet skid performance, it is often difficult to take care of other tires performance
