In 1903, Litchfield, the engineer of Goodyear, developed and patented the world's first wheel tyre, which was presented at several exhibitions. But the invention wasn't meant to come straight away-it was considered unreliable and unsafe. Only half a century later, in 1954, a series of Packard cars fitted with uncrocked tyres were connected to the conveyor belt. What are the differences in the tyre?
What are the differences in the tyre?
The production process is slightly more complex than conventional rubber tyres. The materials and the quality of application of an airtight sealed rubber layer replacing the camera in such a tyre are very high. It must be uniform, firm and firm, without wrinkled and unevenness, otherwise the reliability and durability of the tyre's carcass will be in question: the penetration of the air creates serious stresses, as a result of which the framework starts to relax.
The design of an incalculable tyre means the gravity and dense tension of the beads on the rim flange
A mixture of natural and synthetic rubber is produced. It has a thickness of 1.5 to 3 mm, it is molten to the inner surface of the casing method of vulcanization, that is, it is compressed. This ensures the excellent leakproofness of the beacup tyre. The air is pumpinged through a metal valve, fastened on the rim with a rubber puck and a fastened nut.
The tyres of tyres for the best tightness of embarkation are added to the rim by the on-board belt, made from rubber, rubbres or viscose. During the operation of the casing, the side tape is under severe strain, so it shall be elastic, durable, warm-and freezer. The design of the space tyre means a strong and dense tension on the beads on the rim flange. Wrestes are arranged in such a way that the internal layer of the carcass is turned upside down. The boreal rings of the inverted tires are made of heavy-duty wire.
In the manufacture of [ [ Excessive porch]] tyres, [ [ carcasses]] are used for carcasses from the carcasses or viscose
When producing bare-proof tyres as carcasses, the carcasses use chord or viscose-it is better able to withstand the pressure of compressed air, because its air intightness is 10 to 15 times higher than that of a cotton-made cord.
The application of the self-adhesive coating technology is used abroad in the production of powerless tyres. It is based on the elastic plastic mass, which in the case of punctuation fills the opening and prevents the air from leaving the tyre.
Biceless tyres
Not so long ago, two-half-heared, uncoupler tyres have been developed to improve safety. The outer shell of a two-polish tyre is designed to be incalculable, and a diaphragm within two or three layers of rubbed polyamide threads is installed inside. One cavity is filled with air through the valve. The other is through the valve.
In the case of a punctile or other tyre damage, the air is released from one cavity, which only slightly reduces the performance of the tyre, leaving the air in the other cavity. This makes the journey more secure and does not allow you to take a spare tire with you.
Plusals and disadvantages of tyre rolling tyres
Excessive tyres have a lot of advantages over the chamber. During the movement, they are less heated because there is no friction between the camera and the lid and the heat is more quickly dissipated from the tread to the rim. For the same reason, these tyres are better cooled, which increases their service life.
Due to the fact that the incalculable tyres are lighter, the load on the suspension and the steps is also less.
Unleaved tyres have been used to relieve the car owners of the trouble caused by the transtyranny or refraction of the camera. It is easier to repair them: there is a special pasta for small puncture puncture, which allows you to quickly eliminate the defect without removing the wheels.
The car that is fitted with unkrider tyres is stable and well managed; from the punctured powerless tyre, the air is slower because a strong cord prevents the extension of the punctured punctured cord. So the driver has a few seconds to stop. We can't move on the flat tire, or the germoses will be broken, and the tyre will not be repaired.
Caution and dismantling of chamber tyres should be carried out with maximum care
The weak point of the rubber tyres is taken to think of the sidewalls that are not tough enough to be able to carry a good blow when riding on the derby and the kerb. But it is the gentle sidewalls that make the car's moves even on the not even the most level roads.
The assembly and dismantling of the chamber tyres need to be carried out with extreme caution. If the side paints are damaged, the casing may be unsealed while the vehicle is in motion. Also the cause of the depressurization is the rim contorsions to which the wheel is to be avoided by means of a special means.
This type of tyre has another significant drawback: the airbag that is formed between the camera and the germoso and may cause the tyre to break when the wheel is rapidly rotating or other heavy load on the wheel. It's very rare, though.
