空气弹簧钢丝圈是囊皮两端的刚性密封结构，需承受数十万次高频伸缩而不变形、不漏气，制造精度要求极高。过去，高端钢丝圈缠绕设备长期被德国 Wafios、美国 Bartell 等国际厂商垄断，设备采购与维护成本居高不下。

随着新能源汽车产业的快速发展，国内空气悬架市场正在加速扩容。2026 年中国钢丝圈行业市场规模预计将达到 135.9 亿元，同比增长 6.3%¹，新能源商用车与乘用车空悬配套需求成为核心增长引擎。与此同时，国产空悬供应商持续扩大优势，2026 年 1-5 月孔辉科技、保隆科技、拓普集团三大国产空悬企业合计占据国内 90.8% 的市场份额 ²，产业链本土化进程不断加快，也倒逼上游装备制造向高精度、高效率、智能化方向升级。

从技术趋势来看，六角截面钢丝圈的主流地位进一步巩固。相较于传统圆形截面，六角形钢丝圈周向材料过渡更均匀，动平衡性能更优，2026 年国内半钢子午胎领域六角型技术渗透率预计提升至 85% 左右 ³。这也意味着，空气弹簧钢丝圈制造企业不仅需要提升产能，更需要在截面精度、覆胶稳定性和自动化水平上实现突破。

Air spring beads are rigid sealing structures at both ends of the air spring bladder. They must withstand hundreds of thousands of high-frequency expansion and contraction cycles without deformation or air leakage, which imposes extremely high requirements on manufacturing precision. In the past, high-end bead winding equipment was long monopolized by international manufacturers such as Germany’s Wafios and the United States’ Bartell, resulting in persistently high equipment procurement and maintenance costs.

With the rapid development of the new energy vehicle industry, China’s domestic air suspension market is expanding at an accelerated pace. In 2026, the market size of China’s bead industry is expected to reach 13.59 billion yuan, a year-on-year increase of 6.3%¹. The demand for air suspension supporting systems from new energy commercial vehicles and passenger vehicles has become the core growth engine. Meanwhile, domestic air suspension suppliers continue to expand their competitive edge. In the first five months of 2026, three leading domestic air suspension enterprises — Konghui Technology, Baolong Technology and Tuopu Group — together accounted for 90.8% of the domestic market share². The accelerating localization of the industrial chain is also driving upstream equipment manufacturing to upgrade toward high precision, high efficiency and intelligence.

In terms of technology trends, the mainstream position of hexagonal cross-section beads is further consolidated. Compared with traditional circular cross-sections, hexagonal beads feature more uniform circumferential material transition and better dynamic balance performance. In 2026, the penetration rate of hexagonal technology in China’s semi-steel radial tire sector is expected to rise to around 85%³. This also means that air spring bead manufacturers need to not only increase production capacity, but also achieve breakthroughs in cross-section precision, rubber coating stability and automation level.

本生产线专为六角形、方形截面空气弹簧钢丝圈研发，采用单丝缠绕成型工艺，可在单个生产周期内，全自动缠绕成型3个钢丝圈，适配空气弹簧行业的规模化、高精度生产需求。

This production line is specially developed for air spring beads with hexagonal and square cross-sections. Adopting the single-wire winding forming process, it can automatically wind and form 3 beads within one production cycle, meeting the large-scale and high-precision production requirements of the air spring industry.

当前，中国空气悬架产业正处于从 "跟跑" 到 "领跑" 的关键转折点，国产空簧产品已批量出口海外市场。作为产业链上游的核心装备，空气弹簧钢丝圈单丝缠绕生产线的国产化突破，不仅打破了海外技术垄断，更为中国空悬产业的全球化布局提供了坚实的制程保障。

随着空悬技术向更广泛的车型普及，以及商用车、轨道交通、工业减震等领域需求的持续释放，高精度钢丝圈缠绕设备将迎来更广阔的市场空间，持续推动橡胶机械产业向高端化、智能化方向迈进。

China’s air suspension industry is now at a critical turning point from "following" to "leading", with domestic air spring products already exported in bulk to overseas markets. As core equipment upstream of the industrial chain, the localization breakthrough of the air spring single bead winding line not only breaks overseas technological monopoly, but also provides solid manufacturing support for the global layout of China’s air suspension industry.

As air suspension technology becomes more widely adopted across vehicle models, and demand continues to grow in sectors such as commercial vehicles, rail transit and industrial damping, high-precision bead winding equipment will embrace broader market prospects and continue to drive the rubber machinery industry toward high-end and intelligent development.
