The automobile suspension control arm bush with the rigidity adjustable is simple in structure, and through the arrangement of the baffle plates and the plug plates, nonlinear variation of the rigidity along the radial direction is achieved, and the NVH performance of the bush is promoted.
Description
Technical field
The utility model belongs to the Manufacturing Technology for Automotive Parts field, and more particularly, the utility model relates to a kind of adjustable rigidity automotive suspension Control arm lining.
Background technology
At present, automotive suspension Control arm bush structure mostly is two-tube formation type, is comprised of inner tube, rubber, outer tube three parts, and the three is sulfided into one, and rubber is filled the space between the full inner and outer tubes substantially.Because the radial rigidity of lining depends on the elastic deformation of rubber, and the rubber of this lining is basically identical at cross-sectional area in the radial direction, so the variation of its radial rigidity is directly proportional with radial displacement substantially, namely often be tending towards linear, rigidity does not increase substantially when large displacement, well limit radial movement.For improving the problems referred to above, conventional method has the elastomeric material of adjustment or scantling of structure, but it tends to adjusting process and mould, relates to cost higher, and is difficult to reach NVH performance well.
Summary of the invention
The purpose of this utility model is to propose a kind of adjustable rigidity automotive suspension Control arm lining, distributes with the radial rigidity of improving lining, and improves the NVH performance of lining.
Adjustable rigidity automotive suspension Control arm lining of the present utility model comprises outer tube and is placed in the interior inner tube of outer tube, filling and vulcanization has rubber layer between the inner and outer tubes, key is that the two ends of described lining also are provided with baffle plate, and the plate that rubber layer is axially passed in described baffle plate utilization is connected and fixed; Be provided with the gap between the two ends of described rubber layer and the baffle plate.
When the radial displacement of the outer tube of lining is less, its rigidity only with rubber layer in elastic rubber relation is arranged, this moment, rigidity was less; When the radial displacement of the outer tube of lining increase surpass certain limit after, when namely the end of rubber layer was forced into and offsets with baffle plate, baffle plate will limit the lining outer tube by rubber layer and continue to do radial motion, this moment, rigidity increased sharply.The difference of the external diameter by adding Large lining outer tube diameter and inner tube shortens liner sleeve length or reduces the soil rigidity that the modes such as rubber hardness can reduce lining, has so just realized that the rigidity of lining when little displacement is very little, can relax well impact; The simultaneously two ends by adjusting rubber layer and the gap between the baffle plate can be so that rigidity improve according to certain amplitude when large displacement, thereby limit well the motion of Control arm.
Further, described plate is curvilinear hard plate.When mounted, at first in rubber layer, wear axial hole, then with plate by knocking in the axial hole that is inserted into rubber layer, because plate is curve-like, and axial hole is straight hole, so pack into behind the plate, meeting is so that rubber layer has certain prestress, so that plate is in larger load vibration vertically not.
Further, described plate is for the inner plastic flagstone that metal sheet is arranged that merges, in order to strengthen its axial resistance to tension.
Further, the two ends of described plate are provided with boss and clamp, and the end of plate is provided with radial hole, and described clamp passes described radial hole, thereby baffle plate is fixed between boss and clamp.All there is support at the two ends of baffle plate like this, can avoid baffle plate movable.
Further, an end of described clamp is triangle, the other end be width greater than the rectangle of described radial hole width, the both sides of described clamp are provided with groove.Leg-of-mutton end is conducive to clamp and is inserted in the radial hole, and groove can not come off so that clamp can be clamped in the radial hole.
Further, merge the inside of described clamp metal sheet, improves its supporting capacity.
Further, described plate has a plurality of, and is uniformly distributed in the rubber layer, evenly distributes with each rigidity radially that guarantees lining.
Adjustable rigidity automotive suspension Control arm bush structure of the present utility model is simple, has realized the nonlinearities change of radial rigidity by baffle plate and plate are set, and has improved the NVH performance of lining.
Description of drawings
Fig. 1 is the structural representation of adjustable rigidity automotive suspension Control arm lining of the present utility model.
Fig. 2 is the birds-eye view of adjustable rigidity automotive suspension Control arm lining of the present utility model.
The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, 2, the adjustable rigidity automotive suspension Control arm lining of the present embodiment comprises outer tube 1 and the inner tube 2 that is placed in the outer tube 1, filling and vulcanization has rubber layer 3 between inner tube 2 and the outer tube 1, and the two ends of lining also are provided with baffle plate 4, and baffle plate 4 utilizes the plate 5 that axially passes rubber layer 3 to be connected and fixed; Be provided with gap 6 between the two ends of rubber layer 3 and the baffle plate 4.
Plate is curvilinear hard plate, and its inner fusion has metal sheet 6.When mounted, at first in rubber layer 3, wear axial hole, then with plate 5 by knocking in the axial hole that is inserted into rubber layer 3, because plate 5 is curve-like, and axial hole is straight hole, so pack into behind the plate 5, meeting is so that rubber layer 3 has certain prestress, so that plate 5 is in larger load vibration vertically not.
The two ends of plate 5 are provided with boss 7 and clamp 8, and the end of plate 5 is provided with radial hole, and an end of clamp 8 is triangle, the other end be width greater than the rectangle of described radial hole width, the both sides of clamp 8 are provided with groove.Clamp 8 passes described radial hole, and groove is stuck in the radial hole, thereby baffle plate 4 is fixed between boss 7 and clamp 8.All there is support at the two ends of baffle plate 4 like this, can avoid baffle plate 4 activities (radial hole not shown in FIG. and groove).
Plate 5 has a plurality of, and is uniformly distributed in the rubber layer 3, evenly distributes with each rigidity radially that guarantees lining.
When the radial displacement of the outer tube 1 of lining is less, its rigidity only with rubber layer in elastic rubber relation is arranged, this moment, rigidity was less; When the radial displacement of the outer tube 1 of lining increase surpass certain limit after, when namely the end of rubber layer 3 was forced into and offsets with baffle plate 4, baffle plate 4 will limit lining outer tube 1 by rubber layer 3 and continue to do radial motion, this moment, rigidity increased sharply.The difference of the external diameter by adding Large lining outer tube 1 internal diameter and inner tube 2 shortens liner sleeve length or reduces the soil rigidity that the modes such as rubber hardness can reduce lining, has so just realized that the rigidity of lining when little displacement is very little, can relax well impact; Two ends and the gap between the baffle plate 4 by adjusting rubber layer 3 simultaneously can be so that rigidity improves rapidly according to certain amplitude when large displacement, thereby limits well the motion of Control arm.
