The rim structure of modern hubs is also more and more diversified, and generally speaking, there are two main types of structures: one is a planar or humped spoke with continuous rim; the second is a product with a discontinuous grooved structure of the rim.
The sealing rubber pad of the traditional combined helium testing equipment is poor in universality, troublesome to replace and easy to pollute the environment. The concrete expression is as follows: 1. the rubber pad is made of polyformaldehyde, and the hardness is as high as more than HA 90. The wheel hub has high hardness, poor elasticity and acceptable durability, but has poor universality, can only be used for the wheel hub with a continuous structure of the wheel rim, and cannot be airtight for the wheel hub with the wheel rim with an intermittent groove structure; 2. the rubber pad and the bottom plate are bonded by sealing glue, when the rubber pad is used to be scrapped, in order to save cost, the rubber pad and the bottom plate are separated by using a degumming agent, and then a new rubber pad is replaced for bonding again. The operation in the whole process is long in time consumption and high in difficulty, and the glue is easy to pollute the environment and harm the human health.
