Problems solved by technology

But the performance required for off-road mountaineering and road riding is very different
If the tires commonly used for off-road mountain bikes are ridden on roads, the durability and comfort performance will be greatly reduced, while the tires used for road riding will have insufficient grip and impact resistance if they are ridden on relatively harsh off-road conditions. Tires do not provide full performance
[0003] At present, the tires for off-road mountaineering bikes and road bikes have different designs: the tread pattern of off-road mountaineering bikes is a thicker grain pattern, and the land ratio of the tread is small to obtain enough grip and impact resistance to meet relatively harsh road conditions. , if this type of pattern tire is ridden on a flat road, the durability and comfort performance will be greatly reduced; while the road bicycle tire tread is generally dense and evenly arranged with small grain patterns, the land ratio of the tread is large, and it focuses on low rolling Resistance and comfort, if this type of pattern tire is ridden on relatively harsh off-road conditions, the grip and impact resistance are insufficient
To sum up, there is a large difference in performance between off-road mountaineering and road cycling tires, but new electric or electric-assisted off-road and road crossover models need to have both the above-mentioned performances, which cannot be met by current technologies.
In the past, the performance of dual-purpose tires has also been studied, but it has not been able to break through the trend of ebb and flow in performance, and it is impossible to fully possess

Abstract

The invention discloses a bicycle pneumatic tire tread pattern structure. The tire tread is formed by distributing a plurality of pattern units along the circumferential direction of the tire at intervals; each pattern unit comprises a front pattern unit and a rear pattern unit which is symmetrical along the center line of the tread by the front pattern unit and is arranged at an interval with thefront pattern unit in the circumferential direction; each front pattern unit comprises a first front edge, a second front edge, a first rear edge and a second rear edge; the front end parts of the first front edge and the second front edge are intersected to form a first intersection point; the front end parts of the first rear edge and the second rear edge are also intersected to form a second intersection point; the first intersection point and the second intersection point are respectively positioned on two sides of the center line of the tread; the circumferential lengths of the two axialouter ends of the front pattern unit are different, so that the front pattern unit is of an asymmetric structure as a whole so as to meet two different performance requirements of roads and cross-country mountaineering. The road holding performance during cross-country mountaineering is met, and meanwhile the durability and the comfort during road riding are guaranteed.

Description

【Technical field】 [0001] The invention relates to the technical field of tires, in particular to a tread pattern structure for pneumatic tires of electric or electric assist bicycles. 【Background technique】 [0002] The popularity of electric or electric-assisted bicycles begins with off-road mountain bikes. Electric or electric-assisted off-road mountain bikes (E-MTB) not only have the lightness and convenience of bicycles, but also effectively solve the problem of traditional vehicles going uphill, headwind, and carrying objects. time burden. With the continuous improvement of motor system and battery technology, new models for off-road and road cross-border use have also appeared. This type of model can be used for both off-road mountaineering and road riding. But the performance required for off-road mountaineering and road riding needs is very different. If the tires commonly used for off-road mountain bikes are ridden on roads, the durability and comfort performance ...
