The invention discloses an anti-dive torsion bar middle dustproof structure. The structure comprises a torsion bar, a supporting seat assembly I, a supporting seat assembly II and a middle dustproof sleeve; an annular groove I is formed in the supporting seat assembly I; a bevel edge is arranged on one side edge of the annular groove I; an annular groove II is formed in the supporting seat assembly II; a bevel edge is arranged on one side edge of the annular groove II; a radial flange I and a radial flange II are arranged on the two sides of the middle dustproof sleeve respectively; and the portions, close to the radial flange I and the radial flange II, of the inner circumferential face of the middle dustproof sleeve are inclined faces. The radial flange I is inserted into the annular groove I, the bevel edge of the annular groove I is in contact with the inclined face, close to the radial flange I, of the inner circumferential face of the middle dustproof sleeve in a matched mode; the radial flange II is inserted into the annular groove II, and the bevel edge on the top of one side edge of the annular groove II is in contact with the inclined face, close to the radial flange II,of the inner circumferential face of the middle dustproof sleeve in a matched mode; and therefore, the middle dustproof sleeve is connected between the supporting seat assembly I and the supporting seat assembly II.

    本发明公开一种抗点头扭杆中部防尘结构,包括扭杆、支座组件一、支座组件二和中部防尘套,在支座组件一上开有环形凹槽一,环形凹槽一的一侧边设置有斜边,在支座组件二上开有环形凹槽二,环形凹槽二的一侧边也设置有斜边,中部防尘套的两分别设置有径向凸缘一和径向凸缘二,在靠近径向凸缘一和径向凸缘二的中部防尘套内周面均设置成斜面;通过径向凸缘一插入到环形凹槽一中且环形凹槽一的斜边与靠近径向凸缘一的中部防尘套内周面上的斜面相配合接触以及通过径向凸缘二插入到环形凹槽二中且环形凹槽二的一侧边顶部上的斜边与靠近径向凸缘二的中部防尘套内周面上的斜面相配合接触,从而将中部防尘套连接在支座组件一和支座组件二之间。
