A steering wheel and air bag installation structure comprises a steering wheel framework and an air bag shell, at least three sets of connecting assemblies are arranged between the steering wheel framework and the air bag shell, and the connecting assemblies are limited through fixing clamp springs clamped below the steering wheel framework. The connecting assembly comprises a connecting support, a connecting barb, a horn spring and a supporting spring, the upper end of the connecting barb is movably clamped into a T-shaped clamping groove formed in the bottom face of the air bag shell, the movable gap is larger than the upper limit value of the horn contact stroke, and the lower end of the connecting barb is inserted into an inserting hole formed in the steering wheel framework and clamped through a fixing clamping spring. The horn spring, the connecting support and the supporting spring are sequentially arranged on the connecting barb in a sleeving mode from top to bottom. The connecting support is movably clamped with the bottom of the airbag shell, and the movable gap is greater than the upper limit value of the horn contact stroke; and the connecting support is fixedly clamped with the connecting barb. The structure is good in vibration reduction effect, meanwhile, abnormal sounds generated by contact point contact or horn springback of an automobile steering wheel system can be effectively avoided, and the driving experience of a user is improved.

    一种方向盘与气囊安装结构,包括方向盘骨架和气囊壳体,在方向盘骨架与气囊壳体之间设有至少三组连接组件,连接组件分别通过卡装在方向盘骨架下面的固定卡簧限位;连接组件包括连接支架、连接倒钩、喇叭弹簧和支撑弹簧,连接倒钩上端活动卡入设在气囊壳体底面的T型卡槽内且活动间隙大于喇叭触点行程上限值,连接倒钩下端插入设在方向盘骨架上的插孔内并通过固定卡簧卡接;喇叭弹簧、连接支架和支撑弹簧由上至下依次套设在连接倒钩上;连接支架与气囊壳体底部活动卡接,且活动间隙大于喇叭触点行程上限值;连接支架与连接倒钩固定卡接。该结构减振效果好,同时能够有效避免汽车方向盘系统因触点接触或喇叭回弹而产生异响,提升用户驾驶体验。
