The invention discloses a hub with a tire burst emergency device which comprises an automobile hub body, the automobile hub body further comprises a rim, spokes and a spoke supporting rim, a tire beadseat is arranged in the rim through a wheel flange, an annular groove ring is further arranged at the bottom of the rim, a plurality of protrusions are evenly arranged on the annular groove ring, anda plurality of grooves is formed in the periphery of the annular groove ring. The plurality of bulges forms a tire burst emergency safety device on the annular groove ring; protrusions are formed byrolling or spinning or stamping on the annular groove ring, grooves are correspondingly formed in the other face of the annular groove ring, and therefore the protrusions and the annular groove ring form the integrated hub with the tire burst emergency device. The structure of an existing hub is changed, and the tire burst emergency safety device and the hub are combined into an integrated structure; the improved wheel hub can be engaged with a flat tire after tire burst in a grading manner, so that the flat tire cannot slide laterally, and the technical requirements that the flat tire cannotbe separated from the wheel hub after tire burst, the ground and the wheel hub are effectively isolated, and the control friction force is kept are met.
本发明为一种自带爆胎应急装置的轮毂,包括汽车轮毂,所述的汽车轮毂中还包括轮辋、轮辐,轮辐支撑轮辋,且轮辋中通过轮缘设有胎圈座,轮辋底部还包括环形凹槽圈,在所述环形凹槽圈上设有均匀多个凸起,所述的多个凸起在环形凹槽圈上形成爆胎应急安全装置;所述的多个凸起为环形凹槽圈上辊压、旋压或者冲压制成,在环形凹槽圈的另一面对应形成凹槽,使多个凸起与环形凹槽圈形成一体式结构的自带爆胎应急装置的轮毂。本发明改变了现有轮毂的结构,将爆胎应急安全装置与轮毂复合为一体式结构;改进后的轮毂能级进式啮合爆胎后的瘪气轮胎,保证其不能产生侧向滑移,达到轮胎爆胎后无法脱离轮毂,有效隔离地面和轮毂,保持操控摩擦力的技术要求。
