The specific embodiment
Below will combine accompanying drawing that the utility model is elaborated, but therefore the utility model does not receive any restriction.
Shown in Fig. 1-5, said Control arm rubber bush comprises inner frame 1, outer skeleton 2 and rubber bodies 3.Said rubber bodies 3 is vulcanized the inside face of skeleton 2 outside said and the outside face of said inner frame 1.
Wherein, said inside and outside skeleton 1,2 all in a tubular form, the diameter of said outer skeleton 2 is greater than the external diameter of inner frame 1 and be enclosed within outside the inner frame 1, thereby rubber bodies 3 can be filled between outer skeleton 2 and the inner frame 1.Said rubber bodies 3 is the one loop configuration, and the annular center of said rubber bodies equally also is the annular center of inner frame and outer skeleton, this annular center is called axis L here, and promptly the axis L described in this specification sheets is this annular center.
Said rubber bodies 3 is provided with 4 through holes, is respectively the first, second, third and the 4th through hole 31,32,33,34, said first, second, third and the 4th through hole 31,32,33,34 and runs through rubber bodies 3 along axis L direction.
For the ease of the utility model clearly is described; Like Fig. 4, shown in Figure 5; Water intaking square upwards and the line that intersects of axis L be defined as transverse axis X, get the crossing line of vertical direction and axis L and be defined as longitudinal axis Y, then transverse axis X and axis L constitute first plane; Longitudinal axis Y and axis L constitute second plane, and first plane is perpendicular to second plane.
Said first, second through hole 31,32 respectively with the 4th, the 3rd through hole 34,33 about first plane symmetry, said the first, the 4th through hole 31,34 respectively with second, third through hole 32,33 about second plane symmetry.
Suppose, have three plane vertical with axis L direction in the middle of inner frame 1 height, then the 3rd plane is with 3 fens two parts of rubber bodies: the part that is positioned on the 3rd plane is called on the rubber bodies; The part that is positioned under the 3rd plane is called the rubber bodies lower end.Said rubber bodies top and bottom combine and promptly constitute complete rubber bodies 3 mentioned above.
Like Fig. 3 and shown in Figure 4; Said rubber bodies upper end also comprises first, second gap 41,42; Said first gap 41 is communicated with the first, the 4th through hole 31,34 on axis L direction; Said second gap 42 is communicated with second, third through hole 32,33 on axis L direction, said first, second gap 41,42 is about second plane symmetry.Thereby the side in first gap 41 near outer skeleton 2 forms first protrusion 51, and the side in second gap 42 near outer skeleton 2 forms second protrusion 52, and between first, second gap, forms first solid 61.Said first solid 61 connects inside and outside skeleton 1,2 along longitudinal axis Y; Promptly first solid 6 is coated on the outside of inner frame 1; And along longitudinal axis Y from inner frame 1 both sides are extended and are connected to outer skeleton 2 inboards, thereby inner frame 1 with outside being connected of a crossbeam shape of formation between the skeleton 2.
Preferably, said first, second through hole 31, the distance between 32 be inner frame 1 external diameter 0.9-1.1 doubly.The 0.9-1.1 that said the first, the 4th through hole 31, the distance between 34 are about inner frame 1 external diameter doubly.
Preferably, said first, second gap 41,42 is curved, and is recessed respectively to first, second protrusion 51,52, and the protrusion so that rubber bush when distortion solid can fully be fitted improves its stress deformation.
Preferably, the said first, second, third and the 4th through hole 31,32,33,34 is triangular in shape substantially, one side it leg-of-muttonly presses close to outer skeleton 2.
Said rubber bodies lower end around 90 ℃ of axis L cw or left-hand revolutions and rubber bodies upper end about the 3rd plane symmetry.Particularly; Like Fig. 2 and shown in Figure 5; Said rubber bodies lower end comprises the 3rd, the 4th gap 43,44 equally; Said third space 43 is communicated with first, second through hole 31,32 on axis L direction, said the 4th gap 44 is communicated with the 3rd, the 4th through hole 33,34 on axis L direction, and said the 3rd, the 4th gap 43,44 is about first plane symmetry.Thereby form the 3rd protrusion 53 at third space 43 near a side of outer skeleton 2, the side in the 4th gap 44 near outer skeleton 2 forms the 4th protrusion 54, and in the 3rd, the 4th gap 43, form second solid 62 between 44.Wherein, the 3rd, the 4th protrusion 53,54 of rubber bodies lower end and first solid part 61 of upper end combine, and second solid part 62 of said rubber bodies lower end combines with first, second protrusion 51,52 of rubber bodies upper end.
In addition, preferably, the edge that said rubber bodies 3 and inner frame 1 contact with outer skeleton 2 adopts the arc edge design, with the risk that reduces rubber bodies 3 and inside and outside skeleton 1, separates between 2.
In an embodiment of the utility model, the material of said inside and outside skeleton 1,2 is preferably carbon steel, and other material that satisfies requirement of strength also is fine certainly, such as engineering plastics.Requirement of strength is to confirm that according to concrete stressed in lining place for example the maximum weighted of lining center is 12KN, and the 10# steel that then 2mm is thick just can meet the demands.Therefore according to the force request of said lining in suspension system, in a preferred embodiment of the utility model, the material of said outer skeleton 2 is a carbon steel, and thickness is 1.5-2.5mm; The material of said inner frame 1 also is a carbon steel, and thickness is 6-7mm.
Said rubber bodies 3 can be processed by common polysulphide rubbers; At inside and outside skeleton 1, between 2 before the polysulphide rubbers body 3; In order to make inside and outside skeleton 1,2 be connected more firm with rubber bodies 3; Reach to rubber bodies 3 and inside and outside skeleton 1, Joint strenght requirement between 2 inside face of skeleton 2 and the outside face coating adhesive of inner frame 1 outside before the sulfuration.Employed a kind of coupling agent when said lining cement is meant the skeleton and the vulcanization of rubber, lining cement such as adhesives relatively more commonly used now: primer CH205 face glue CH6253.
Said rubber bodies 3 is vulcanized in the inside face of outer skeleton 2 and the outside face of inner frame 1 according to the structure described in the preceding text; Thereby can process the Control arm rubber bush of the utility model; This rubber bush and Control arm body interference fit can adopt press to be pressed into during assembling.
This new control arm rubber lining when the adjustment radial rigidity, has been broken through the restriction of rubber hardness.Through the variation of structure, the adjusting control arm rubber lining is the rigidity of all directions radially, and balance bush traveling comfort and handling performance satisfy the requirement of vehicle debugging.Simultaneously, this kind new control arm rubber lining has better endurance quality than the lining that merely reaches rigidity requirement through the adjustment elastomeric material.
