one of the main components of the tube of automobile tires, it is an annular rubber tube, having a good elasticity, and can heat. For the generation of wrinkles in the tube inflated state, which should be slightly smaller than the size of the effective size of the inner wall of the casing.
1. The structural characteristics of the tube
with the filling tube, the bleed valve, which has a cylindrical metallic holder, the bottom of the flange is inserted through the slit valve on the tube inner tube hole . Rubber reinforcing braid and tube aperture edge of the pad and tightly wrap the cartridge holder, it nuts clamped between two gaskets, so that the valve mounted on the inner tube tightly. When the tire is mounted on a wheel, it is fixed to the valve hole in the rim. Block valve core barrel equipped with the sealing liner. The bushing has an annular groove embedded rubber seals. When the nut is screwed, the conical concave seat ring i.e. the pressing of the seat tube. A cylindrical screw on the outside of the seat belt cover cap rubber seal, which can handle as the valve core is screwed the nut wrench. Below the liner with rubber valves. When the tire is inflated, air pressure valve is depressed; after inflation is complete, the spring sleeve put it on the rod tightly against the valve seat.
2. Tubeless pneumatic tire
tubeless tire in appearance and structure of the tubeless tire approximation, the difference is added on the inner wall of a tubeless tire casing layer thickness of 2 ~ of 3mm rubber seal designed to seal gas layer. It is adhered thereto by the method of vulcanization. In the self-adhesive layer facing the sealing layer against the floor below the tread with special unvulcanized rubber mixtures prepared. When the tire is perforated self-adhesive layer be self-adhesive pierced hole, named self-adhesive layer has a tubeless tire.
is the advantage of a tubeless tire: tire puncture when the pressure does not drop drastically, continue driving safely; absent due to friction between the inner casing and the damage caused by jamming; airtight than good, heat can be directly through the rim, the operating temperature is low, a long service life; simple structure, less mass.
is a tubeless tire drawbacks: it is difficult to repair the middle; in addition, the self-adhesive layer when the adhesive in order not only the size of the perforations; self-adhesive layer may be softened and flows downwardly hot weather, thus destroying wheel balancing. Therefore, the general use of a tubeless tire and non-self-bonding layer. It is only one of the inner wall of the casing the sealing layer, and when the tire puncture, because of its own in a compressed state aspirate cling round, it can not leak long. Even if the puncture was pulled out, tubeless tires will only fail when a tire burst.
3. Classification tube
can be divided by the main material contained in natural rubber and butyl rubber inner tube inner tube, there is a new additional pure product butyl rubber inner tube.
The main properties of butyl rubber inner tube: butyl rubber inner tube colloidal autistic better performance, having high airtightness and high temperature resistance. Anti-aging, use longer.
Applicable Market: butyl rubber inner tube according to the specifications and supporting the use of tire specifications, can be divided into a truck inner tube, light truck inner tubes, construction vehicle inner tubes, motorcycle inner tubes, bicycle inner tubes and rickshaw with inner tubes.
