The invention discloses a special sand tire and wear resistance detection device thereof. The special sand tire comprises a tire body, wherein a tire tread is formed on an outer ring of the tire body,a tire shoulder is formed on an edge of the tire tread, a plurality of pattern blocks are arranged on the tire tread and the tire shoulder, and the pattern blocks are symmetrically arranged on the left side and the right side of the circumferential axis of the tire tread in a staggered mode; each pattern block comprises a tread pattern block group arranged on the tread and distributed along the circumferential direction of the tire, and a tire shoulder pattern block group arranged on the tire shoulder and distributed along the circumferential direction of the tire, and the tail end of the tire shoulder pattern block group extends towards the tire side to form an under-shoulder pattern block. According to the special sand tire, a computer model is established to simulate the size and shapeof a grounding mark, the grounding pressure and distribution condition, and the contact condition of a pattern and a soft pavement of a tire in soft lands such as deserts, sand lands, beaches and thelike so as to design a pattern groove with a U-shaped structure and an undirected blocky pattern block; the passing rate of the special sand tire on a soft road surface is increased, the functions ofwater drainage, mud discharge, sand discharge and the like are improved, stability and the quick turning performance of a vehicle are improved, and meanwhile the control performance of the tire is improved.

    本发明公开了一种特种沙地轮胎及其耐磨检测装置,其包括:胎体,胎体外圈形成有胎面,胎面边沿形成有胎肩,胎面和胎肩上设有若干个花纹块,花纹块以胎面周向轴左右两侧对称交错布置,花纹块包括设于所述胎面上沿轮胎周向分布的胎面花纹块组,及设于胎肩上沿轮胎周向分布的胎肩花纹块组,胎肩花纹块组的末端向胎侧延伸形成肩下花纹块。本发明建立计算机模型,模拟轮胎在沙漠、沙地、海滩等松软地的接地印痕大小与形状,接地压强高低与分布状况,花纹与松软路面的接触情况,设计出U型结构花纹沟及无向块状花纹块,提高了本特种沙地轮胎在松软路面通过率及排水、排泥、排沙石等功能,提高车辆的稳定性及快速转弯性能,同时提高了轮胎的操控性能。
