Rubber bushing assembly afterwards, it is characterised in that:The bulb pin assembly include mounting seat, base, dust cover, bolster, bulb and
The body of rod being connected with bulb, the mounting seat, base and dust cover constitute receiving cavity, are provided with the mounting seat and supply bulb
The mounting groove being put into, the bolster is located in mounting groove, and the outer wall of the bolster is inconsistent with the inwall of mounting groove, the buffering
The inwall of part is inconsistent with the surface of bulb, and the middle part of the bolster is arranged with the middle part gap of base, the gap portion structure
Into buffering cavity.
By adopting above-mentioned technical proposal, the mounting groove being put into for bulb is provided with mounting seat, bolster is located at peace
In tankage, the outer wall of bolster inwall inconsistent with the inwall of mounting groove and bolster is inconsistent with the surface of bulb, protects
It is not in that shaking phenomenon occurs in mounting groove to have demonstrate,proved bulb, it is ensured that stability, is that buffering is prepared;And in bolster
Portion is arranged with the middle part gap of base, and the gap portion constitutes buffering cavity, when bolster is impacted by bulb, the cushion chamber
Body awards bolster individual resilience space, makes bolster have a preferable resilience force, so as to the buffering that improve bulb pin assembly is imitated
Really, it is ensured that reduce control arm body in use and be subject to vehicle body or vibrating produced by wheel, reduce vehicle body or
Impulsive force of person's wheel to control arm body, it is ensured that control arm body is not in easily to rupture, and so as to extend the longevity is used
Life.
This utility model is further arranged to:The width of the bolster from bolster two ends respectively toward bolster
Portion tapers into.
By adopting above-mentioned technical proposal, the non-deformability of bolster is improve, it is slow so as to also further improve
Rush effect.
This utility model is further arranged to:The lid for preventing bulb from coming off from mounting groove is provided with the mounting seat
Plate.
By adopting above-mentioned technical proposal, it is ensured that when bulb pin assembly is subject to external impacts, in the bulb pin assembly
Bulb will not come off from mounting groove, it is ensured that the service life of bulb pin assembly, so as to improve buffering effect.
