Inflatable tire

Abstract

The invention provides an inflatable tire which comprises anti-sliding nails, a tire face portion, a tire shoulder portion and grooves formed in the tire face portion and the tire shoulder portion. The grooves extend upwards in the width direction of the inflatable tire from the center line of the tire face portion and penetrate through the tire face portion and the tire shoulder portion in the width direction of the inflatable tire. According to the inflatable tire, flake ice or snow can be timely discharged so that the dewatering performance of the tire on ice can be improved; due to the fact that the flake ice or the snow left on the inflatable tire is reduced, the probability that the inflatable tire slides on the ice is reduced, the ground gripping performance is obviously improved, and the starting performance, the braking performance and the manipulation performance of the inflatable tire on the ice are more ideal.

Description

technical field [0001] The invention relates to the technical field of tires, and more specifically, to a pneumatic tire. Background technique [0002] Pneumatic tires are one of the key accessories for normal driving of a car, and they include various types, such as all-season tires applied to ordinary roads, and ice tires applied to ice fields. [0003] Such as figure 1 As shown, it is a schematic diagram of the structure of the grounding part of the ice tire. In order to make the ice tire have better operating performance such as starting and braking on the ice, and to prevent it from slipping on the ice, the tread part 01 and the shoulder of the ice tire The part 02 is a stud pattern, that is, the tread part 01 and the shoulder part 02 are provided with the pattern and the anti-skid stud 03 that can penetrate the ice surface, such as figure 1 shown. Among them, the arrangement of the anti-skid studs 03 on the entire contact portion is: linearly distributed on 6 parall...

AI Technical Summary

Problems solved by technology

[0005] 1. If figure 1 As shown, the central line of the tread portion 01 does not have the conduction groove 04 extending continuously with the shoulder portion 02, and the ice or snow debris remaining on the central line of the tread portion 01 has no discharge path, which will affect the tire on ice. poor drainage performance and grip performance, resulting in poor traction, start-up, braking performance and other handling performance on ice

[0006] 2. If figure 1 As shown, there are only three kinds of setting positions of the studs 03 on the contact area, but for ice tires, the less the number of studs 03 distributed in the unit contact area, the distribution mode and position type of the studs 03 The less it is, the worse the ability to grip on ice, so the stud 03 has only 3 ice tires with 3 settings, and its handling performance on ice is not ideal

[0007] 3. If figure 2 As shown, the second pattern block 05 located on the tread portion 01 has a rounded edge divided by the groove 04, and the radius of the rounded corner is 15 mm to 25 mm, and the rounded part 06 has a large arc. For ice tires In terms of the tread pattern, the existence of the rounded part 06 will reduce the anti-skid and handling performance of ice tires on ice
