" axially inner side on " and " axially external on " be respectively intended to mean " in the axial direction from
The equatorial plane closer to " and " farther from the equatorial plane in the axial direction "." radial distance " be compared with the distance of the rotation axis of tire,
" axial distance " is the distance compared with the equatorial plane of tire." radial thickness " measures in radial directions, and " axial width " exists
It is measured on axial direction, " circumferential lengths " are the length of circular arc in circumferential direction.
Tire of the prior art generally includes：Crown, two tyre beads and two sidewalls, crown includes being intended to and ground
The tyre surface contacted by tire surface, two tyre beads are intended to contact with wheel rim, and crown is connected to tyre bead by two sidewalls.The prior art
In commonly used in the carcass reinforcement of radial of the heavy vehicle of construction site type generally include at least one body piles,
The body piles are wrapped in the reinforcement for being referred to as being coated with the usually metal in the elastomeric material of blend.Body piles
Including major part, two tyre beads are combined together by the major part, and the inside from tire in each tyre bead is outside
The circumferential reinforcing element that gusset the usually metal for being referred to as bead winds to form crimping.The metal enhancing of body piles
Body is substantially parallel to each other, and forms the angle between 85 ° and 95 ° with circumferential direction.The meridian of construction site heavy vehicle
The crown reinforcement of tire is included in the overlapping of crown layer circumferentially disposed on the radial outside of carcass reinforcement.Each crown layer
Reinforcement including being usually metal, reinforcement are mutually parallel and are wrapped in elastomeric material or coating blend.Existing skill
Crown reinforcement in art includes at least one work reinforcement, and work reinforcement includes at least two working linings, and working lining exists
On the radial outside of carcass reinforcement and on the radially inner side of tyre surface.Work reinforcement including at least two working linings has band

Between angle.When driving vehicle crosses the obstacle with the magnitude size for for example making deformations of tyre under the nominal load of tire
During object, the flexibility at face causes crown deformation without damaging under the line.Above-mentioned crown structure, in the process of running, it is same this
Kind flexibility causes to be present in the high-caliber deformation of elastomeric material in crown at tire shoulder, and it is high to generate elastomeric material
Temperature.Under the hot environment reached, possessed resistance when the elastomeric material of crown can lose part for crack causes
Crown durability is made to be deteriorated.This crack of elastomeric material can cause the separation of working lining in extreme circumstances, and then be formed
Crown divides.

The narrow hoop layer for the angle that manufacture reinforcement forms about 8 ° with circumferential direction means the sheared length for being more than 2.5m along length
Narrow hoop layer (i.e. outside the scope of commercially available industrial machine) is sheared, and welds narrow hoop layer before curing along this equal length
Tire is connected to, this requires know-how and the accuracy close to twice laying working lining or protective layer.Second defect is wheel
Tire is to there are the susceptibilitys of the relevant impact of big barrier on path.Particularly, in the case of impact, away from crown
The stone narrow hoop layer of property axis is subjected to significantly being forced to deformation, causes the damage or rupture of crown reinforcement, causes tire
Failure.Since when squeezing, tire needs are indeformable as much as possible, so the hoop layer of this type cannot be moved close into
Property axis.Use the narrow hoop layer of elasticity or use and the relevant stiff narrow hoop layer of the first working lining, the first working lining
Reinforcement angle at least equal to 50 °, though the technical issues of shock-sensitive that can solve to include the crown of narrow hoop layer is spent, to the greatest extent
The impact resistance that they improve crown is managed, but considers the size in some barriers that the place of tire is used to be run into,
These schemes cannot ensure the mechanical integrity of crown in all cases.
Since tire has the geometry shown compared with rotation axis rotational symmetry, so the geometry of tire is led to
Often described in the middle plane of the rotation axis containing tire.For given middle plane, radial direction, axial direction and circumferential direction side
To the direction for representing the rotation axis perpendicular to tire respectively, parallel to tire rotation axis direction and perpendicular to the side of middle plane
To.
