The invention discloses a positioning sleeve. The positioning sleeve is provided with a first inner elastic positioning part used for carrying out elastic radial positioning on a guide sleeve arrangedon an air bag assembly, a second inner elastic positioning part used for carrying out axial limiting and auxiliary elastic radial positioning on a blind rivet, a third inner elastic positioning partused for carrying out radial positioning on the blind rivet, and an outer elastic positioning part used for carrying out elastic radial positioning on a positioning hole formed in the steering wheel body. The invention further discloses a positioning matching structure comprising the positioning sleeve and an automobile steering wheel assembly comprising the positioning matching structure. The positioning sleeve is arranged among the guide sleeve and the blind rivet of the air bag assembly and the positioning hole of the steering wheel body for elastic positioning fit, a gap existing between the air bag assembly and the positioning hole of the steering wheel body is eliminated, and problems of a vibration abnormal sound of the air bag assembly and horn switch pressing clamping stagnation can be fundamentally solved.

    本发明公开的一种定位套,至少具有对设置在气囊组件上的导向套筒进行弹性径向定位的第一内弹性定位部、对拉钉进行轴向限位及辅助弹性径向定位的第二内弹性定位部、对拉钉进行径向定位的第三内弹性定位部以及对设置在方向盘本体上的定位孔进行弹性径向定位的外弹性定位部。还公开了包含该定位套的定位配合结构和包含该定位配合结构的汽车方向盘组件。本发明通过在气囊组件的导向套筒、拉钉与方向盘本体的定位孔之间设置定位套进行弹性定位配合,消除气囊组件与方向盘本体的定位孔之间存在的间隙,可以从根本上解决气囊组件的振动异响和喇叭开关按压卡滞的问题。
