Detailed description of the invention
Refer to Fig. 1 to Fig. 5, contriver of the present utility model, in order to understand the technical solution of the utility model better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
Refer to Fig. 1, Fig. 2 and Fig. 4, a kind of automobile control arm lining of the present utility model, comprise the radial inner frame 1, polysulphide rubbers obturator 2 and the purchasing ore 3 that from inside to outside set gradually.Inner frame 1 and purchasing ore 3 are all that aluminum alloy is made.Inner frame 1 is identical with the height of purchasing ore 3, formed for placing polysulphide rubbers obturator 2 between the two, the annular space that two ends are run through, making polysulphide rubbers obturator 2 when producing distortion with automobile control arm motion, having certain space to compensate polysulphide rubbers obturator 2 and being out of shape the volume change produced.
Purchasing ore 3 is thin-wall tubular structure, and the external metallization structure interference fit of its excircle and automobile control arm, can protect the polysulphide rubbers obturator 2 being positioned at its radially inner side.
Inner frame 1 is the axis rhombus tubular column parallel with the axis of purchasing ore 3, and namely inner frame 1 comprises a rhombus cylinder 11, and it is circular through hole 12 that the center of rhombus cylinder 11 has a cross sectional shape axially parallel with it.The hole wall of through hole 12 has circumferential wave groove 13, as shown in Figure 3.Through hole 12 is divided into three sections in axially connecting, i.e. entrance cylindrical section 121, middle frustum section 122 and outlet cylindrical section 123.Wherein the aperture of entrance cylindrical section 121 is greater than the aperture of outlet cylindrical section 123.On two end faces of inner frame 1, correspondence has the first blind hole 14 and the second blind hole 15, to meet positioning requirements when automobile control arm lining and automobile control arm axle head assemble, as shown in Figure 4.Adopt the reason of rhombus tubular column to be: whole automobile control arm lining is larger than Fy direction in Fz direction displacement variable, therefore needs Fz to spacing, inner frame 1 requires that Fz is large to the thickness of metal, and Fx is axially loaded direction.
Refer to Fig. 1, polysulphide rubbers obturator 2 is provided with four hollow structures, comprise two semicircle hollow structures 21 arranged in Mirror Symmetry, and two dumb-bell shape hollow structures 22 arranged in Mirror Symmetry, wherein, two semicircle hollow structure 21 correspondences are positioned at the two ends of the minor axis of the diamond-shaped cross-section of rhombus cylinder 11, and two dumb-bell shape hollow structure 22 correspondences are positioned at the two ends of the major axis of the diamond-shaped cross-section of rhombus cylinder 11.Such design modifying Fz is to the overall rigidity value with Fy upwards whole automobile control arm lining.Simultaneously, adopt semicircle hollow structure 21 and dumb-bell shape hollow structure 22 two kinds of hollow structures, the space of inner frame 1 can make up the large volume change of four hollow structure place polysulphide rubbers obturators 2, and adjustment Fz is to the overall rigidity value with Fy upwards whole automobile control arm lining.Wherein Fz displacement variable is large, is principal direction, therefore in dumb-bell shape hollow structure 22 purchasing ore 3 side of polysulphide rubbers obturator 2, be designed with inwardly protruded rubber gasket structure 23, as shown in Figure 1 and Figure 4, play limiting buffer effect, Fz is subject to shearing force to polysulphide rubbers obturator during stand under load 2; And Fy is relatively little to displacement variable, polysulphide rubbers obturator 2 under tension and pressure, require large at this directional stiffness, four sections of rubber filling bodies define semicircle hollow structure 21 and dumbbell shape hollow structure 22.
Refer to Fig. 5, the transition of automobile control arm axle head stepped shaft, ensure the Joint strenght between automobile control arm axle head and automobile control arm lining, the structure be axially connected with outlet cylindrical section 123 by entrance cylindrical section 121, middle frustum section 122 of through hole 12, meets the cooperation requirement of automobile control arm axle head stepped shaft transition.Middle frustum section 122 place, the hole wall of through hole 12 is level and smooth.Simultaneously between the end face of rhombus cylinder 11 and the hole wall of the entrance cylindrical section 121 of through hole 12, add chamfering 16, meet the cooperation requirement of automobile control arm axle head stepped shaft transition further.
The utility model can improve magnitude of interference when automobile control arm and automobile control arm lining assemble, and ensures there are enough binding forces between automobile control arm and automobile control arm lining.The problem of elastic conjunction between the automobile control arm lining solving prior art.
The entrance cylindrical section 121 of through hole 12 and the hole wall of outlet cylindrical section 123 are furnished with circumferential wave groove 13, during elastic conjunction, be compensated in the circumferential wave groove 13 that the peak valley that the rough external surface of the ladder shaft part of automobile control arm exists can be pressed into the through hole 12 of inner frame 1.When automobile control arm axle head outside face is pressed into the through hole 12 of inner frame 1, the first circumferential wave groove 13 of squeezing through-hole 12, decreases the large magnitude of interference and causes stress to concentrate, and protects inner frame 1 entirety and avoids destroying.
The squeeze and destroy that the hole wall of the large magnitude of interference to the through hole 12 of inner frame 1 when circumferential wave groove structure 13 reduces assembling causes, in turn ensure that the large magnitude of interference of hole wall of the through hole 12 of the inner frame 1 of automobile control arm axle head and automobile control arm lining assembles simultaneously, ensure that both Joint strenghts.
According to practical set situation and the display of road test result, a kind of automobile control arm lining of the present utility model is meeting client on automobile control arm lining sound rigidity requirement basis, reduce the difficulty of elastic conjunction between automobile control arm lining and automobile control arm, ensure that the Joint strenght of elastic conjunction between the two, extend the service life of this place's automobile control arm lining, meet client's operating needs.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
