Heat dissipation performance, particularly full-steel radial ply vacuum tire are very economical durable.
In order to meet the dress tire of vacuum tire, sealing and inflation requirement, need respectively to set a circle in the wheel rim both sides of wheel hub
The hill that can be fitted closely with vacuum tire.However, the size of hill i.e. cannot it is less than normal can not be bigger than normal, if less than normal, hold
Easily wheel hub is made to be bonded with vacuum tire not close, and then be easy to cause vacuum tire habitual abortion gas leakage or even hitting vacuum tire
Pressure is detached from wheel rim after declining suddenly when hitting.If bigger than normal, can cause to be difficult to install vacuum tire to wheel hub, if
Installing by force will cause to damage to the surface of vacuum tire.
Therefore, the key parameter when size of hill is wheel hub processing must be detected it in production.It is existing
Detection mode be to be sampled detection using Ball tape rule, need wheel hub taking special monitor station and go artificial detection, examine
It surveys less efficient and only inspects by random samples, testing result also is difficult to timely and accurately be recorded, and dates back is poor, and then causes
It is very inconvenient when subsequently needing to handle detection data.
