客户使用中痛点的解决/Solve the pain points in customer use：

1：关于轮毂开裂破损：我们使用高标准高强度铸件确保轮毂在使用中不会开裂破损/ About wheel hub cracking and breakage: We use high standard and high strength castings to ensure that the wheel hub will not crack and break during use。

2：关于螺栓断裂：螺栓使用40CR材质等级为10.9级的高强度高精度汽车轮毂螺栓，杜绝使用中螺栓的断裂确保行驶安全。同时我们强烈建议客户用车前做好螺母拧紧的检查，防止螺母未拧紧的情况下轮圈对螺栓进行剪切运动造成螺栓损伤/ About bolt breakage: The use of 40CR material grade 10.9 high-strength and high-precision automotive hub bolts to prevent the breakage of bolts in use to ensure driving safety. At the same time, we strongly recommend customers to check the nut tightening before using the car, so as to prevent the bolt damage caused by the shear movement of the wheel ring on the bolt when the nut is not tightened。

3：关于轴承质量：采用高质量高精度轴承，不仅确保高速行驶的稳定也极大提升产品使用寿命/ Bearing quality: The use of high-quality high-precision bearings not only ensures the stability of high-speed driving but also greatly improves the service life of the product

4：关于润滑：采用HP-R高温润滑脂预润滑，在产品全周期内不需要加注润滑脂，极大提高客户使用的便利性，做到免维护免保养；/ About lubrication: The use of HP-R high temperature grease pre-lubrication, in the whole cycle of the product does not need to fill grease, greatly improve the convenience of customer use, maintenance free.

5：关于密封：使用全包胶的三唇油封和高精度一次拉伸成型的防尘盖，进一步提升轮毂的密封性能，确保外部杂质无法进入轮毂造成轮毂轴承的卡死，烧结等损坏。/ About sealing: The use of all-coated three-lip oil seal and high-precision one-stretch dust-proof cover to further improve the sealing performance of the hub, to ensure that external impurities can not enter the hub, resulting in the hub bearing stuck, sintering and other damage.

6：关于车轴弯曲或断裂：主要是由于车轴材料选择错误，材料工艺问题，严重的外力冲击，严重超载等；因此车轴材料我们采用45#钢或Q345钢，严格禁止使用冷拔钢，因为冷拔钢存在内部应力集中的风险，加工工艺上采用CNC整体一次成型加工。Axle bending or breaking: mainly due to the wrong selection of axle materials, material process problems, serious external impact, serious overload, etc.; Therefore, we use 45# steel or Q345 steel for axle materials, and the use of cold-drawn steel is strictly prohibited, because there is a risk of internal stress concentration in cold-drawn steel, and CNC precision machining is used in processing technology.

7：关于轮胎飞脱：主要是因为轮毂轴头的锁紧螺母安装错误及轮毂螺母未及时紧固有关，我们提供专业的安装规范及指导。About the tire flying off: mainly due to the wheel hub shaft head lock nut installation error and the wheel nut is not tightened in time, we provide professional installation specifications and guidance。
