4.1.21. A design of the radial tyre

Fig. 4.20. The Cross-section of the radial tyre: 1 – the protector block; 2 – a protector flute; 3 – a protector; 4 – a nylon bandage; 5 – cord layers; 6 – the board core; 7 – the board amplifier; 8 – protection onboard закраины
|
Nylon bandage 4, layers of a cord 5, cores of a board 6 and amplifiers of a board 7 base a skeleton. The skeleton is a bearing element tyres.
Damages from blows
Camber in sidewallsе specifies tyres in skeleton damage.

Fig. 4.21. Arrival on a border at an acute angle
|
Typical "originators" of similar damages are, for example, borders at arrival on them at an acute angle ( fig. 4.21). Because of it the skeleton of the so strongly compressed tyre can be damaged.
The tyre skeleton thus is strongly stretched that leads to rupture of separate fibres.
The damage scale depends on speed and a corner of blow, pressure of air in tyres, loadings on an axis and an obstacle kind.

THE NOTE
Arrival on borders should be avoided.
If to drive on a border all the same it is necessary, through its edge it is necessary to move at an obtuse angle and very slowly.

Fig. 4.23. The tyre with the broken off skeleton, a kind from within
|
Because of strong blow the skeleton was jammed at onboard закраины and broke off in a contact point ( fig. 4.23).
Internal damage of the tyre because of blow (double rupture)
The double rupture which has resulted compression at arrival on a border, is frequently imperceptible outside ( fig. 4.24).
