All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to the attached drawings 1-3, the application discloses a semi-steel engineering tire, which comprises a tire body 10, wherein the tire body 10 is provided with a tire tread 11, a tire body 12, a tire bead 13, a tire bead 14 and an inner liner 15, a steel wire belt layer 16 is arranged between the tire tread 11 and the tire body 12, a steel wire belt is arranged in the steel wire belt layer 16, a buffer layer 23 is arranged between the tire tread 11 and the steel wire belt layer 16, buffer particles are filled in the buffer layer 23, and the buffer particles have elasticity.

It should be noted that, the cushion particles may be made of rubber, latex or plastic, in this embodiment, the cushion particles are the same as the tire itself, and can be cut up by leftover materials after processing the tire to be filled, so as to improve the utilization rate of the tire material, the steel wire belts are provided with two layers, and are adhered to each other by an adhesive, and are installed in the steel wire belt layer 16 together, so as to adhere and install the steel wire belts on two sides, so as to reduce the occupied space of the steel wire belts in the tire body 12, improve the stability of the tire body 12, the gap formed by cutting the tire surface 11 with the crushed stones is smaller than the size of the cushion particles, at this time, the gap just occurs, the cushion particles can well block outside substances in the cushion layer 23, when the gap occurs greatly, the cushion particles fall from the gap, and remind the user that the tire should be replaced.

Based on above-mentioned scheme, this semi-steel engineering tire is through setting up buffer layer 23 between steel wire bundle belt 16 and tread 11, and pack the buffering granule in buffer layer 23, make rubble and tread 11 cutting form the breach after, rubble, ponding or other materials submerge earlier in buffer layer 23 and cushion the granule contact, and the separation is in buffer layer 23 under the effect of buffering granule, avoid contacting with steel wire bundle belt 16, thereby solve among the prior art rubble cutting tread 11 after, rubble, ponding or other materials enter into steel wire bundle belt 16, the problem of wearing and tearing or corruption steel wire bundle belt, and then improve the life of this tire.

Further, be equipped with first elastic layer 20 between inner liner 15 and steel wire harness belting 16, the length dimension of first elastic layer 20 is greater than the length dimension of steel wire harness belting 16, through setting up first elastic layer 20, make first elastic layer 20 can disperse steel wire harness belting 16 at the stress of car formation process on the one hand, avoid steel wire harness both ends to receive residual stress's influence and perk, on the other hand makes steel wire harness earlier with first elastic layer 20 contact, make the car at the operation in-process, it extrudees inner liner 15 to reduce steel wire harness, avoid inner liner 15 damaged, reduce the possibility of this tire blowing out.

Further, a second elastic layer 21 is provided between the cushion layer 23 and the steel belt layer 16, and the length dimension of the second elastic layer 21 is larger than that of the steel belt layer 16.

Specifically, through setting up second elastic layer 21 for there is the interval between buffer layer 23 and the steel wire harness belting 16, and the buffering granule separates with the steel wire harness area, reduces the contact of buffering granule and steel wire harness area, avoids the piece on the buffering granule to adhere to on the steel wire harness area, influences the life of steel wire harness area.

In conclusion, when the broken stones are to be cut to cause tire burst, the tread 11 must be cut first to enter the buffer layer 23, the broken stones penetrate through the buffer particles and then cut the second elastic layer 21, the broken stones can enter the steel wire band layer 16 to be in contact with the steel wire band, the first elastic layer 20 can be cut after the steel wire band layer 16 is worn, and finally the first elastic layer is in contact with the inner liner layer 15, so that the tire can be damaged, the broken stones are effectively prevented from being in contact with the steel wire band through layer-by-layer arrangement in the tire body 12, and the service life of the tire is effectively prolonged.

Referring to fig. 2 and 3, the tread 11 is provided with a plurality of first grooves 40, the groove walls of the first grooves 40 form an angle a with the tread 11, and the angle a is set to 100 ° or more and 120 ° or less.
