Description

Tread protection truck radial tire mining area operation pattern

Technical Field

The utility model relates to a field of tire decorative pattern, concretely relates to tread protection load radial tire mining area operation decorative pattern.

Background

For the truck radial truck mining tire, due to factors such as heavy bearing weight, large traction force, complex road conditions and the like, in order to meet index requirements such as ground gripping performance, wear resistance, heat dissipation performance and the like, different types of pattern structures are generally adopted on the tread of the radial truck mining tire to meet the performance requirements.

For example, the tread pattern of the most common truck radial tire for mining adopts a wavy pattern groove, and the tread is transversely (axially) arranged at intervals to divide the tread into blocks which are uniformly distributed on the circumference, and the truck radial tire has the following defects in use:

1. the trend of the pattern groove is less in the transverse direction and more in the longitudinal direction, so that the transverse holding force of the tire is insufficient and the tire is easy to sideslip;

2. each pattern block is relatively independent and large in area, is easy to creep to generate temperature rise, is slow in heat dissipation and is easy to age;

3. foreign matters are easy to be clamped into the groove, so that the foreign matters are difficult to be discharged, and the tread is easy to damage.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a tread protection load radial tire mining area operation decorative pattern, have the advantage that the grip is strong, heat dispersion is good, long service life.

The purpose of the utility model is accomplished through following technical scheme: the tread protection heavy-duty radial tire mining area operation pattern comprises pattern grooves, pattern blocks are formed between the pattern grooves, each pattern groove comprises a plurality of left and right wavy pattern grooves which are distributed on a crown on two sides of a tread central line at intervals and in a staggered mode, a V-shaped stepped groove is arranged in each wavy pattern groove, the inner sides of the adjacent left and right wavy pattern grooves are connected in an inclined mode at the tread central line, a V-shaped groove is arranged at the connection position, and the outer side of each wavy pattern groove transversely extends from the crown to a tire shoulder; the stepped groove of V type's bottom interval arrangement have a plurality of enhancement protective layers, be provided with the boss between two parties on this enhancement protective layer, the stepped groove bottom of V type between the adjacent boss is provided with the strengthening rib between two parties, the strengthening rib bottom is connected on strengthening the protective layer.

As a further technical scheme, the V-shaped stepped groove at least has two steps.

As a further technical scheme, the top of the reinforcing rib is flush with the top of the reinforcing block.

As a further technical scheme, the width of the wavy groove transversely extending to the tire shoulder is gradually reduced.

The utility model has the advantages that:

1. the transverse wavy pattern groove (namely wavy pattern block) structure is adopted, so that the transverse and longitudinal ground holding force of the tire is reasonably distributed;

2. the wavy pattern groove with the V-shaped stepped grooves and the reinforcing protective layer arranged at the bottom of the wavy pattern groove enhance the rigidity of the pattern blocks, reduce the creeping temperature rise in the running process of the tire, have better heat dissipation performance and prevent the advanced aging of the tire;

3. the reinforcing block is arranged on the reinforcing protective layer, so that the self-cleaning capability of the tire is enhanced, and the service life of the tire is prolonged;

4. the reinforcing ribs are adopted to connect the reinforcing blocks, so that the stability of the reinforcing blocks is improved.

Fig. 2 is a sectional view a-a of fig. 1.

Fig. 3 is a sectional view B-B of fig. 1.

Description of reference numerals: the tire comprises a wavy tread groove 1, a tire crown 2, a tire shoulder 3, a V-shaped stepped groove 4, a reinforcing protective layer 5, a reinforcing block 6, a reinforcing rib 7 and a V-shaped groove 8.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): as shown in attached figures 1-3, the tread protection heavy-duty radial tire mining area operation pattern comprises pattern grooves, pattern blocks are formed between the pattern grooves, and the pattern grooves are respectively arranged on a tire crown 2 and a tire shoulder 3 on two sides of a tread center line. Parallel interval establishes the wavy tread groove 1 of left side position on the left child of tread central line 2, parallel interval establishes the wavy tread groove 1 of right side position on the child of tread 2 on tread central line right side, a left side, the wavy tread groove 1 reverse symmetry and dislocation each other that the right side corresponds, dislocation distance just makes a left side, the interior side of the wavy tread groove 1 that the right side corresponds is connected in the slant on the tread central line (the interior side slant upper right side of left wavy tread groove 1, the interior side slant left side below of right wavy tread groove 1), use the wavy tread groove 1 of left side top in fig. 1 as an example:

the wave type pattern groove 1 comprises a left wave band (oblique upper right), a middle wave band (oblique lower right) and a right wave band (oblique upper right) at the outer side part, the left wave band of the wave type pattern groove 1 transversely extends to a tire shoulder 3 and the width of the left wave band is gradually reduced, the cross section of the wave type pattern groove 1 of the right wave band is a traditional V-shaped groove 8, the cross section of the wave type pattern groove 1 of the left wave band and the middle wave band is a V-shaped stepped groove 4 with three equal height steps, four reinforcing protective layers 5 are arranged at the bottom of the V-shaped stepped groove 4 at intervals, two reinforcing protective layers 5 are arranged in the wave type pattern groove 1 of the right wave band, one reinforcing protective layer 5 is arranged in the wave type pattern groove 1 at the junction of the left wave band and the middle wave band, a reinforcing block 6 with the height smaller than the third step is arranged in the middle of each reinforcing protective layer 5, the trend of each boss 6 is unanimous and unanimous with the length that corresponds reinforcing layer 5 with the slant that corresponds the wave band, all is equipped with vertical strengthening rib 7 between the adjacent boss 6 between the middle, and 7 bottoms of strengthening rib are connected on reinforcing

layer
