Mode is assemblied in the lantern ring.That is the present invention has carried out two parts and has optimized in existing automotive suspension control arm assembly technology：One
It is that the outer surface of the outer skeleton of the bush Assembly of traditional control arm assembly is designed to band external thread structure, the lantern ring is arranged to
With the internal thread structure coordinated with it.The lantern ring and bush Assembly use Screw assembly form, can freely assemble, dismantle, can
Assembling is repeated several times, does not produce plastic deformation.Overcome problem existing in the prior art.
Further, one end of the outer skeleton of bush Assembly is designed as hexagon flange surface structure.During assembling, available active is pulled
Bush Assembly is screwed into the lantern ring of structure control arm assembly by hand or special tooling by hexagonal flange, easy to assembly.
Further, chamfering is designed in the hexagonal flange root of skeleton outside bush Assembly, can effectively prevent stress
While concentration, outer root interference problem of the skeleton after being connected with collar thread of bush Assembly can also be avoided.
Further, in planar structure of the outer circumferential side designed for coordinating spanner or tiger's jaw pincers of the lantern ring, during assembling, spanner is used
Or tiger's jaw clamp handles the planar structure of the lantern ring, control arm assembly can be fixed, easy to the assembling of bush Assembly.
The present invention also protects a kind of automobile, its automotive suspension control arm assembly with aforementioned structure.
Compared with conventional art, the bush Assembly at this automotive suspension control arm assembly both ends（The bush Assembly at both ends is identical）
It can arbitrarily dismantle, it can be replaced after the damage of flimsy bush Assembly, to non-damageable control arm welding assembly
Reused.In the Performance Match work of new model, control arm welding assembly can also be may be reused, only to two
The bush Assembly at end is replaced as needed, and so convenient maintenance, part replacement, can reduce maintenance cost, economize on resources.
