Description
技术领域 technical field
本实用新型涉及一种轮胎，具体是提供轻便高强度聚氨酯轮。The utility model relates to a tire, in particular to provide a light and high-strength polyurethane wheel.
背景技术 Background technique
现有技术下，通用的轮胎制作都是一体成型制作轮芯，轮芯与外部轮辋及橡胶的结合需要多个连接件，这样的产品结构不但需要更多的生产成本，而且长时间使用后很容易造成外部橡胶脱落。Under the existing technology, general-purpose tires are made of integrally formed wheel cores. The combination of wheel cores, external rims and rubber requires multiple connectors. Such a product structure not only requires more production costs, but also is very expensive after long-term use It is easy to cause the outer rubber to fall off.
发明内容 Contents of the invention
本实用新型是针对以上问题，提供一种轻便高强度聚氨酯轮，其增强了轮芯与其外部聚氨酯外圈的结合强度，使其不易脱落。The utility model aims at the above problems and provides a light and high-strength polyurethane wheel, which strengthens the bonding strength between the wheel core and its external polyurethane outer ring, making it difficult to fall off.
本实用新型解决其技术问题所采用的技术方案是：The technical scheme that the utility model solves its technical problem adopts is:
一种轻便高强度聚氨酯轮，由轮芯和轮芯外部包覆的聚氨酯外圈构成，轮芯外围的轮辋设置有通孔，所述聚氨酯外圈穿过所述通孔包覆在轮辋外部。A light and high-strength polyurethane wheel is composed of a wheel core and a polyurethane outer ring coated on the outside of the wheel core. The rim around the wheel core is provided with a through hole, and the polyurethane outer ring passes through the through hole and is coated on the outside of the rim.
轮辋呈凸字形。The rim is convex.
本实用新型的轻便高强度聚氨酯轮，轮芯的轮辋部分改用凸字形结构，在凸出的中间部位有通孔，聚氨酯外圈与轮辋接触面积加大，聚氨酯外圈通过轮辋的通孔贯穿包住轮辋凸出部位。这样制作的单轮有良好的回弹性。聚氨酯外圈与轮芯结合强度增加，解决了轮芯与聚氨酯外圈分开的问题。且单轮起滚动阻力降低，物理性能得到大的提高。In the light and high-strength polyurethane wheel of the utility model, the rim part of the wheel core is changed to a convex structure, and there is a through hole in the middle part of the protrusion, the contact area between the polyurethane outer ring and the rim is enlarged, and the polyurethane outer ring penetrates through the through hole of the rim Cover the rim protrusion. The single wheel made in this way has good resilience. The bonding strength of the polyurethane outer ring and the wheel core is increased, which solves the problem of separation of the wheel core and the polyurethane outer ring. Moreover, the rolling resistance of the single wheel is reduced, and the physical performance is greatly improved.
与现有技术相比，本实用新型的轻便高强度聚氨酯轮，其具有设计合理、结构简单、制作成本低、使用寿命久的特点。Compared with the prior art, the portable high-strength polyurethane wheel of the utility model has the characteristics of reasonable design, simple structure, low manufacturing cost and long service life.
