Abstract

The utility model relates to a control arm, the control arm body that has a three support arm that forms including integrative casting, be provided with bulb round pin assembly, preceding rubber bush assembly and back rubber bush assembly on the tip of three support arm respectively, its characterized in that: bulb round pin assembly includes mount pad, base, dust cover, bolster, bulb and the body of rod of being connected with the bulb, the middle part of bolster sets up with the middle part clearance of base, and this clearance part constitutes buffering cavity, the utility model discloses lie in: just the middle part of bolster and the middle part clearance of base set up, and this clearance part constitutes buffering cavity, and when making the bolster receive the bulb impact, this buffering cavity awards the bolster has individual rebounding space, and messenger's bolster has a better resilience force to improved the buffering effect of bulb round pin assembly, guaranteed to have reduced automobile body or wheel and to the impact force of control arm body, guaranteed that very easily splitting can not appear in the control arm body, thereby prolonged life in the use.

Description

A kind of control arm

Technical field

This utility model is related to technical field of automobile parts, is specifically related to a kind of control arm.

Background technology

Control arm is safety member and guide important in automobile chassis system, subjects the various loads in running car Lotus, its intensity, rigidity have decisive influence to vehicle performance.Guiding and power transmission unit of the control arm as automobile suspension system Part, the various power that will act on wheel pass to vehicle body, while ensureing that wheel is moved by certain track.Automobile control arm is distinguished Wheel and flexible chassis are linked together by ball pivot or bushing.

At present, existing automobile-used control arm on market, it includes the control arm with three support arms that integrally casting is formed Body, is respectively arranged with bulb pin assembly, front rubber bushing assembly and rear rubber bushing assembly on the end of three support arms, due to Bulb pin assembly shock-absorbing capacity is poor, and arm body is controlled in use can be subject to produced by vehicle body or wheel shaking energetically It is dynamic, control arm body can be caused easily to rupture, so as to shorten service life.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of control for increasing the service life Arm.

What the technical solution of the utility model was realized in：A kind of control arm, including integrally casting formed with three The control arm body of individual support arm, be respectively arranged with the end of three support arms bulb pin assembly, front rubber bushing assembly and 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.
