《GB/T 16622-2022压配式实心轮胎规格、尺寸与负荷》由TC19（全国轮胎轮辋标准化技术委员会）归口，TC19SC1（全国轮胎轮辋标准化技术委员会汽车工农业机械轮胎轮辋分会）执行，主管部门为中国石油和化学工业联合会。
Introduction
Analysis of core changes in the standard revision
The 2022 new standard makes the following key improvements on the basis of maintaining the original technical framework:
- Integrate non-equivalent references of the ISO 10500 international standard concept
- Add applicable specifications for other industrial vehicles besides counterbalanced forklifts
- Refine the requirements for multi-system specification representation where imperial/metric coexist
Comparison of technical indicators between the old and new versions
| Parameter dimension | Improvements in the 2022 version | Requirements of the 2009 version |
|---|---|---|
| Tire specification representation | Distinguish between imperial/metric>Metric systemTwo progressive systems | Undefined measurement system window |
| Speed conditions | Added 6km/h, 10km/h load parameters | Only standardize the basic speed end |
| Equipment coverage | Expand special industrial vehicles such as warehousing and logistics | Focus on traditional logistics equipment |
| Steel rim-rim combination | Added standard tolerance for rim outer diameter matching | Only describe the design margin |
Key technical points for implementation and application
Key practical recommendations based on the implementation of the new regulations:
- Preferably use metric-marked press-fit tires to improve replacement compatibility
- Chapter 5.3 Rim size tolerances refer to GB/T 16623 testing standard
- Newly added 381-630 specification segments require focus on testing outer diameter dispersion
- 6-10km/h operating conditions recommended reduction factors expand the boundaries of transportation equipment selection
Technology evolution and development background
Since its first release in 1996, it has gone through three iterations, reflecting three major technical thrusts:
- China's high-speed construction machinery in 2019: driving the demand for multi-condition load splitting
- Popularization of intelligent warehousing systems: standardization and improvement of miniaturized carcasses for narrow aisle equipment
- Technical innovation of multi-support structure shock absorption leads to correction of CT value of rim interference fit
