Thus, if compression load viaUpside installation component 10 and load on vibrationproof matrix 30, the upper end 35 of vibrationproof matrix 30 limiting unit on left and right directions is subject to12 and the restriction of upper carrier 14, and the restriction of face 13 on above-below direction is subject to. Its result, can prevent vibrationproof matrixDepart from the position of 30 upper end 35, therefore, compression load can be loaded on to vibrationproof via upside installation component 10Matrix 30.

The bottom 23 of lower installation component 20 is the positions for the bottom 31 at above-below direction restriction vibrationproof matrix 30. The endPortion 23 extends and arranges in the direction of reporting to the leadship after accomplishing a task mutually with the lower wall portion 21 that is formed with lower through hole 20a. Particularly, bottom left 23bAnd right bottom 23d extends and arranges towards oblique upper outside with respect to left lower wall portion 21b and right lower wall portion 21d; Front bottom 23a and afterBottom 23c extends and arranges towards horizontal direction outside with respect to front lower wall portion 21a and the 21c of posterior inferior wall portion. Like this, due to bottom 23In the direction of reporting to the leadship after accomplishing a task mutually with lower wall portion 21, extend and arrange, therefore, when the compression load of above-below direction loads on vibrationproof matrix 30Time, can prevent that the bottom 31 of vibrationproof matrix 30 from departing from from downside installation component 20 downwards.

As shown in Figures 5 and 6, the length front bottom 23a of downside installation component 20 and rear bottom 23c, in horizontal directionDegree is set for and is greater than bottom left 23b and right bottom 23d. In addition, left upper wall portions 24b and right upper wall portions 24d are formed as along up and downThe tabular surface of direction, on the other hand, has been connected to form laterally (fore-and-aft direction) at front upper wall portions 24a and rear upper wall portions 24cThe front lower rake 25a of expansion and after the 25c of portion that has a down dip. In addition, bottom 23, upper wall portions 24 and the portion's 25 formation extensions that have a down dip are establishedPut portion 22, described extension setting unit 22 is extended and is arranged towards the direction of reporting to the leadship after accomplishing a task with above-below direction from the surrounding of lower through hole 20a.

Front lower rake 25a and after the 25c of portion that has a down dip be front extension 32a and the rear expansion for bearing vibrationproof matrix 30The position of the 32c of portion. The front linking part 34a of vibrationproof matrix 30 is for linking front extension 32aJi Qian bottom 31a and front upperThe position of end 35a, rear linking part 34c is the portion for linking rear extension 32c and the 31c of posterior end portion and rear upper end 35cPosition. Due to be provided with front lower rake 25a and after the 25c of portion that has a down dip, therefore, can make to extend setting unit 22 and become large. Its result,The front linking part 34a of vibrationproof matrix 30 and the horizontal direction thickness of rear linking part 34c, can set for and be greater than left linking part 34bAnd the horizontal direction thickness of right linking part 34d. Can make the volume of the vibrationproof matrix 30 of fore-and-aft direction (arrow F-B direction) be greater thanThe volume of the vibrationproof matrix 30 of left and right directions (arrow L-R direction), therefore, can be by the fore-and-aft direction of antihunting device 1 (arrow F-B direction) spring constant be set as being greater than the spring constant of left and right directions (arrow L-R direction).

In addition, with regard to left linking part 34b and right linking part 34d, upper and lower at left linking part 34b and right linking part 34dThe outer surface of the substantial middle of direction, is formed with depressed part 34b1,34d1 along fore-and-aft direction. By depressed part 34b1,34d1A part of thickness attenuation of left linking part 34b and right linking part 34d can be made, therefore, left linking part 34b and right company can be madeKnot 34d easily deforms, and can further reduce the spring constant of left and right directions.

With regard to vibrationproof matrix 30, be formed with recess 38,39 at the inner peripheral surface of intercommunicating pore 30a. Recess 38 is formed on downsideThe horizontal level of the downward-extension board 26 of installation component 20, recess 39 separates predetermined distance with recess 38 and is formed on recess 38Top. Recess 38,39 is towards the direction of reporting to the leadship after accomplishing a task with above-below direction and the setting of caving in, and corresponding with depressed part 34b1,34d1Position separate gap and be set up in parallel up and down. Recess 38,39 respectively at the circumferencial direction of whole intercommunicating pore 30a with ring-typeBecome, and each axial section is formed as circular-arc. Because recess 38,39 is formed between bottom 31 and upper end 35, because ofThis, if compression load loads on vibrationproof matrix 30, vibrationproof matrix 30 is out of shape in the mode of the outside expansion to inserting hole 30a.

At this, be not formed with recess 38,39, if vibrationproof at the inner peripheral surface of the intercommunicating pore 30a of vibrationproof matrix 30Matrix 30 deforms on above-below direction, easily from be formed at downside installation component 20 through hole 20a come off. If anti-The matrix 30 that shakes comes off from downside installation component 20, and downside installation component 20 departs from from vibrationproof matrix 30, and following it to have canCan exist vibrationproof performance to reduce or send the worry of extraordinary noise.

To this, according to antihunting device 1, the vibrationproof matrix 30 being out of shape be urged to downside installation component 20 bottom 23, onWall portion 24 and the portion 25 that has a down dip, therefore, the vibrationproof matrix 30 that can prevent from being loaded with compression load is from bottom 23 and the portion 25 that has a down dipDepart from downwards. Its result, can prevent that vibrationproof matrix 30 from departing from from downside installation component 20.

In addition, because the axial section of recess 38,39 is with circular-arc formation, therefore can suppresses compression stress and concentrate on recessedPortion 38,39. Its result, can suppress to cause vibrationproof matrix 30 deteriorated based on recess 38,39. In addition, due to recess 38,39 withThe position that depressed part 34b1,34d1 are corresponding, separates gap and is set up in parallel up and down, therefore, easily makes vibrationproof by recess 38,39Matrix 30 deforms, and can suppress to be caused by recess 38,39 the excessive attenuation of thickness of vibrationproof matrix 30. Its result,The spring constant that can prevent the left and right directions (arrow R-L direction) of vibrationproof matrix 1 too diminishes.

Intercommunicating pore 30a with the internal diameter (width of the arrow R-L direction of Fig. 5) of its left and right directions from below towards recess 38 byThe mode that gradual change is large forms. Thus, can make the thickness attenuation of the vibrationproof matrix 30 of left and right directions (Fig. 5 arrow R-L direction), a left sideThe spring constant of right (arrow L-R direction), compared with the spring constant of fore-and-aft direction (arrow F-B direction), can be set forLittle spring constant.

As shown in Figure 5, with regard to the upper limiting unit 12 of upside installation component 10, the bottom left of itself and downside installation component 2023b and right bottom 23d are opposed and arrange, and are positioned at deflection intercommunicating pore 30a center with respect to bottom left 23b and right bottom 23dPosition. Thus, by upper limiting unit 12, bottom left 23b and right bottom 23d, can be by definite the compression load of above-below directionLoad on to get involved and be arranged on the left linking part 34b of the vibrationproof matrix 30 between downside installation component 20 and upside installation component 10And right linking part 34d. This be because, if compression load loads on vibrationproof matrix 30, by being formed at the recessed of vibrationproof matrix 30Portion 38,39, vibrationproof matrix 30 is out of shape in the mode of the outside expansion to inserting hole 30a, on this basis, upper limiting unit 12 with underThe bottom left 23b of side installation component 20 and right bottom 23d are opposed and arrange, and upper limiting unit 12 with respect to bottom left 23b andRight bottom 23d is positioned at the position at deflection intercommunicating pore 30a center.

As shown in Figure 6, with regard to the upper limiting unit 12 of upside installation component 10, the front bottom of itself and downside installation component 2023a and rear bottom 23c are opposed and arrange, and are positioned at deflection intercommunicating pore 30a center with respect to front bottom 23a and rear bottom 23cPosition. Thus, by upper limiting unit 12, front bottom 23a and rear bottom 23c, can be by definite the compression load of above-below directionLoad on to get involved and be arranged on the front linking part 34a of the vibrationproof matrix 30 between downside installation component 20 and upside installation component 10And rear linking part 34c. This be because, if compression load loads on vibrationproof matrix 30, by being formed at the recessed of vibrationproof matrix 30Portion 38,39, vibrationproof matrix 30 is out of shape in the mode of the outside expansion to inserting hole 30a, on this basis, the change of vibrationproof matrix 30Shape is obstructed by front bottom 23a and rear bottom 23c.

In addition, upper limiting unit 12 up-wards inclination more more toward the outer side, front lower rake 25a and after the 25c of portion that has a down dip get over courtGet over laterally up-wards inclination. Thus, can the compression load of above-below direction of vibrationproof matrix 30 will be loaded into, as perpendicular to upperLimiting unit 12, front lower rake 25a and after have a down dip the 25c of portion inclined plane component and work. Due to upper limiting unit 12 phasesFor front lower rake 25a and after the 25c of portion that has a down dip be positioned at the position at deflection intercommunicating pore 30a center, therefore can suppress bendingStress or cut off effect of stress in vibrationproof matrix 30, thus can guarantee the high spring spy of fore-and-aft direction (arrow F-R direction)Property.

With regard to upside installation component 10, two positions, place, front and back of portion 13, are formed with on plate thickness direction and pass through in the aboveLogical upper through hole 13a. On the other hand, with regard to vibrationproof matrix 30, at front upper end 35aJi Hou upper end 35c, with upper perforationThe position of hole 13a is provided with outstanding upward lug boss 36 accordingly. Lug boss 36 is to be slightly less than the internal diameter of upper through hole 13aMode form, and its length setting is to be greater than facial 13 thickness. Be greater than the side in the aperture of upper through hole 13a with diameterThe fastener 36a that formula forms, extends to the periphery of lug boss 36 in the tip side of lug boss 36. Due to the diameter of fastener 36aExpand gradually downward from top, therefore can, by outstanding lug boss 36 and the fastener 36a that is arranged on vibrationproof matrix 30, insertEnter to the upper through hole 13a that is formed at upside installation component 10. Although vibrationproof matrix 30 is non-bondings with upside installation component 10, but lug boss 36 and fastener 36a are inserted in after upper through hole 13a, can upside be installed to structure by fastener 36aPart 10 is fixed on vibrationproof matrix 30.

In addition, with regard to vibrationproof matrix 30, downward-extension setting unit 37 is extended setting downwards from bottom 31, and arrangesThere is the laterally extending setting unit 37a extending towards horizontal direction outside from the top of the whole circumference of downward-extension setting unit 37. UnderThe above-below direction length setting that extends setting unit 37 becomes to be greater than the above-below direction length of lower wall portion 21, laterally extending setting unit 37aThe mode that is positioned at the outside of the lower wall portion 21 of downside installation component 20 with its top is set. Thus, can make vibrationproof matrix 30There is strain in downward-extension setting unit 37 and laterally extending setting unit 37a, and is inserted into the lower perforation of downside installation component 20Hole 20a. Although vibrationproof matrix 30 is NAG with downside installation component 20, by downward-extension setting unit 37 and laterally extendingSetting unit 37a is inserted into after lower through hole 20a, can downside installation component 20 be fixed on by laterally extending setting unit 37aVibrationproof matrix 30. In addition, because the lower side top at laterally extending setting unit 37a is chamfering, therefore can easily insert,To the lower through hole 20a of downside installation component 20. By structure being installed at vibrationproof matrix 30 fixed upper installation components 10 and downsidePart 20, can improve assembling operation when antihunting device 1 is installed on to the carrying in the process of vehicle body frames BF and installsProperty.

Then, with reference to Fig. 7 to Figure 10, vibrationproof matrix 30 is described. Fig. 7 is the front view that vibrationproof matrix 30 is shown, figureThe 8th, the side view of vibrationproof matrix 30 is shown, Fig. 9 is the top view that vibrationproof matrix 30 is shown, Figure 10 is the X-X illustrating along Fig. 9The cutaway view of the vibrationproof matrix of line. Because vibrationproof matrix 30 is unbondedly got involved and is arranged on upside coupling member 10 and downside and linksBetween member 20, therefore can independently enter as other members different from upside coupling member 10 and downside coupling member 20Row vulcanization forming.

As shown in Figures 7 and 8, the front lower extension 32a of vibrationproof matrix 30 and rear lower extension 32c are not arranged at front upperThe 31a of wall portion and rear upper wall portions 31c whole, but be arranged at front upper wall portions 31a and rear upper wall portions 31c left and right directions inHeart portion. Thus, front lower extension 32a and rear lower extension 32c are difficult to have influence on left and right directions (the arrow R-L side of antihunting device 1To) spring constant. Its result, can increase fore-and-aft direction (arrow F-B direction) spring constant, with left and right directions (arrowR-L direction) the ratio of spring constant.

As shown in Figure 9, inserting hole 30a has in the time overlooking the roughly inner peripheral surface of rectangular shape, at whole vibrationproof matrix 30Above-below direction be formed through. At the lug boss of the outstanding front upper end 35aJi Hou upper end 35c that is arranged at vibrationproof matrix 3036, be formed with and inject oral area 36b. Injecting oral area 36b is to carry out vulcanization forming at vibrationproof matrix 30 by sulfurizing mould (not shown)Time, with the position that is formed at hand-hole sulfurizing mould, rubber-like elasticity material (not shown) link. Thus, anti-in useWhen vibrating device 1, vibrationproof matrix 30 is not easy to produce be full of cracks.

That is, vibrationproof matrix 30 is members that strain occurs in the time using antihunting device 1, and the root place of injecting oral area isEspecially easily produce that stress is concentrated when antihunting device 1 and concentrate the place that easily produces be full of cracks because of this stress using. RightThis, the stress that acts on the lug boss 36 of giving prominence to upward from the upper end 35 of vibrationproof matrix 30 is little, therefore, by lug boss36 form injection oral area 36b, can be difficult to produce at the root place of injecting oral area 36b be full of cracks. Its result, can prevent in vibrationproofMatrix 30 produces be full of cracks and the phenomenon of reduction durability.

As shown in figure 10, outstanding to be arranged at compared with the 35d of end, upper right thickness large and after volume is larger for lug boss 36Upper end 35c (and front upper end 35a). Lug boss 36 is vibrationproof matrix 1 to be installed to vehicle body frames BF and power set PPProcess in, for improving carrying property and installation property, for upside installation component 10 being fixed on to the position of vibrationproof matrix 30. Pass throughLug boss 36 is arranged to rear upper end 35cJi Qian upper end 35a, and lug boss 36 is arranged to end, upper left 35b and upper rightThe situation of end 35d is compared, while carrying in the process that vibrationproof matrix 1 is installed on to vehicle body frames BF and power set PP etc.,Can suppress lug boss 36 that fracture occurs and cause vibrationproof matrix 30 and upside installation component 20 to disperse.

In addition, because vibrationproof matrix 30 is NAG with upside installation component 10 and downside installation component 20, therefore, anti-The matrix 30 that shakes not is that integrated vulcanizing is bonded in upside installation component 10 and downside installation component 20, but conduct and upside are installed structureOther members that part 10 and downside installation component 20 are different and independently carry out vulcanization forming. Therefore, can improve and be used for making vibrationproofThe design freedom of the sulfurizing mould of matrix 30 vulcanization formings, thus can easily form as undercutting at inserting hole 30a(undercut) recess 38,39.

Then with reference to Figure 11, the using method of antihunting device 1 is described. Figure 11 illustrates to be assembled in vehicle body frames BFAnd the cutaway view of antihunting device 1 under the state of power set PP. As shown in figure 11, antihunting device 1 is by being inserted through front extensionThe bolt (not shown) of the 26e of hole portion of board 26a and rear extension board 26c, is fixed on vehicle body frames BF. Support BR is fixed on movingThe upper end side of power apparatus PP. Support BR is roughly criss-cross member in the time of side-looking, and it is given prominence to and is arranged at power set PP'sTop. Support BR is inserted into the inserting hole 30a of antihunting device 1 from below. The axis-shaped component B such as bolt are inserted through and are formed on installing plateThe 11a of hole portion of portion 11, and screw thread is incorporated into support BR.

If axis-shaped component B is combined with the support BR screw thread that is positioned at inserting hole 30a, and by the upper end side of axis-shaped component BBe fixed on the 11a of hole portion, power set PP is in via antihunting device 1 and support BR and be hung at the state of vehicle body frames BF,Power set PP is subject to the resiliency supported of vibrationproof matrix 30. As shown in figure 11, vibrationproof matrix 30 is subject to the deadweight of power set PPAnd it is compressed at above-below direction. Due to vibrationproof matrix 30 the whole circumference of the inner peripheral surface of inserting hole 30a be formed with recess 38,39, therefore, be out of shape in the mode of expanding laterally with respect to inserting hole 30a at the compressed vibrationproof matrix 30 of above-below direction. ByThis, vibrationproof matrix 30 pushes to the extension setting unit 22 (bottom 23, lower wall portion 24 and the portion 25 that has a down dip) of downside installation component 20,Therefore, can suppress vibrationproof matrix 30 comes off downwards from inserting hole 30a.

As mentioned above, by antihunting device 1 is installed, at the load on of beating in antihunting device 1 in the situation that, upper extension boardPortion 15 and downward-extension board 26 (front extension board 26a etc.) performance is as the function of spring stop, extension 33 (forward extensions33a etc.) play the effect of shock absorbing. In addition, at the load on of beating, in antihunting device 1 in the situation that, fore-and-aft direction extendsThe extension board BR1 of support BR and bottom 23 (rear bottom 23c etc.) or lower wall portion 21 (21c of posterior inferior wall portion etc.) bring into play as bulletJump the function of stop.

In addition, the above-below direction length setting that is positioned at the support BR of inserting hole 30a is to be shorter than the nature of vibrationproof matrix 30Length. The above-below direction length setting of support BR is, beats load and vibrationproof matrix 30 extends and (recovers former upward when being loaded withShape) time while being subject to bouncing the restriction of stop, the size that vibrationproof matrix 30 can not separate from downside installation component 20. ByThis, can be suppressed between downside installation component 20 and vibrationproof matrix 30 and to change the extraordinary noise causing because of friction or pressureGeneration.

In addition, the upper limiting unit 12 of upside installation component 10 and front bottom 23a and the rear bottom 23c of downside installation component 20Opposed and arrange, and be positioned at the position at deflection intercommunicating pore 30a center with respect to front bottom 23a and rear bottom 23c, therefore, energyThe compression load of enough above-below directions loads on front linking part 34a and rear linking part 34c definitely. Further, owing to front having a down dipTiltedly the 25a of portion and after the 25c of portion that has a down dip be connected to form with front bottom 23a and rear bottom 23c respectively, therefore, can prevent vibrationproof baseThe position deviation of body 30, and can increase the volume of front linking part 34a and rear linking part 34c. Its result, before and after can guaranteeingThe spring constant of direction.

Then,, with reference to Figure 12 and Figure 13, Figure 34 to Figure 36, load by contrasting to illustrate with comparative example the load of beatingTime the action of antihunting device 1. First,, with reference to Figure 34 to Figure 36, the antihunting device of comparative example is described. In addition, forThe part identical with the content describing in the first embodiment, is used identical Reference numeral, and omits following sayingBright. Figure 34 is the stereogram that vibrationproof matrix 930 comparative example, that be used in antihunting device is shown, Figure 35 illustrates comparative exampleThe top view of vibrationproof matrix 930, Figure 36 is the cutaway view illustrating along the vibrationproof matrix 930 of the XXXVI-XXXVI line of Figure 35. ThisWith the vibrationproof matrix 930 that is installed on upside installation component 10 and downside installation component 20, replace in the first embodiment outward,The vibrationproof matrix 30 of the antihunting device 1 illustrating antihunting device as a comparative example, make the antihunting device of the first embodiment 1For the antihunting device of embodiment.

As shown in FIG. 34 and 35, vibrationproof matrix 930 possess be formed as truncate quadrangular pyramid body and in the time overlooking, be roughlyRectangular-shaped linking part 934, while overlooking, roughly the inserting hole 930a of rectangular shape is formed through at whole above-below direction. As Figure 36Shown in, with regard to linking part 934, the thickness difference of fore-and-aft direction and left and right directions, rear linking part 934c (and front linking partThickness 934a) is set as being greater than the thickness of right linking part 934d (and left linking part 934b). Be not formed with at linking part 934The recess 38,39 of explanation in the first embodiment, the inner peripheral surface of the intercommunicating pore 930a of linking part 934 forms with flat condition. Separately, be not formed with depressed part 34b1,34d1 at vibrationproof matrix 930 outward, the surface of linking part 934 forms with flat condition.

Suppose the antihunting device of the antihunting device of embodiment 1 and comparative example to be installed on vehicle body frames BF, and fixing movingPower apparatus PP, with computer to loaded in the situation of the load of beating of formed objects, the action of vibrationproof matrix 30Simulate.

Figure 12 is the phantom that the antihunting device 1 of the embodiment that is loaded with the load of beating is shown, Figure 13 illustrates to addBe loaded with the phantom of the antihunting device of the comparative example of the load of beating. The two is analog result. In addition, for easy understandingFigure 12 and Figure 13, illustrate 1/4 Slicing Model for Foreign, and omit the diagram of support BR.

In the antihunting device 1 of the embodiment shown in Figure 12, vibrationproof matrix 30 is close to front bottom 23a and right bottom 23d,And there is the compression of above-below direction in vibrationproof matrix 30 between upside installation component 10 and downside installation component 20. On holdMeet portion 15 and be not contacted with forward extension 33a, front linking part 34a and right linking part 34d bear the load of beating.

To this, in the antihunting device of the comparative example shown in Figure 13, carry out with the antihunting device 1 (with reference to Figure 12) of embodimentRelatively, can learn from the gap smaller between upside installation component 10 and downside installation component 20, vibrationproof matrix 930 is from downsideInstallation component 20 separates and declines. Can be clear and definite in comparative example, vibrationproof matrix 930 (front linking part 934a) is failed fullyBear the load of beating. This is because be not formed with recess 38,39 at the vibrationproof matrix 930 of comparative example. Can infer, due to shape notBecome to have recess 38,39, vibrationproof matrix 930 is difficult to deform laterally, thereby separates with respect to downside installation component 20.

In addition, in the antihunting device of comparative example, between downside installation component 20 and right linking part 934d, be formed with veryLarge gap. This is because the right linking part 934d of vibrationproof matrix 930 occurs very large in the mode that is " く " word shape to the inside, there is decline displacement with respect to downside installation component 20 in distortion simultaneously. Inner side towards right linking part 934d deforms, be byIn be not formed with recess 38,39 at vibrationproof matrix 930. In addition, with respect under the downside installation component 20 of right linking part 934dFall displacement, its reason is also not to be formed with depressed part 34b1,34d1 on the surface of right linking part 934d.

As mentioned above, because the antihunting device of comparative example is not formed with recess 38,39, therefore vibrationproof at vibrationproof matrix 930Matrix 930 is difficult to deform laterally, and vibrationproof matrix 930, with respect to downside installation component 20, decline displacement or inside occursSide deforms, and separates thus from downside installation component 20. If vibrationproof matrix 930 occurs to divide from downside installation component 20From, likely reduce vibrationproof performance or send extraordinary noise. To this, according to the antihunting device 1 of embodiment, due in vibrationproofThe inner peripheral surface of the inserting hole 30a of matrix 30 is formed with recess 38,39, therefore can make vibrationproof matrix 30 easily become laterallyShape. In addition, owing to being formed with depressed part 34b1,34d1 on the surface of right linking part 934d, therefore can make right linking part 934dEasily bend, suppress the decline displacement of right linking part 934d. Thus, can make vibrationproof matrix 30 be difficult to, from downside, structure is installedPart 20 separates, and can guarantee the vibrationproof performance of antihunting device 1, and can prevent extraordinary noise. By guaranteeing vibrationproof dressPut 1 vibrationproof performance, can guarantee the spring constant of above-below direction, and the spring constant of fore-and-aft direction is set as being greater than left and rightThe spring constant of direction.

Then,, with reference to figs. 14 to Figure 23, the second embodiment is described. Illustrate in the first embodiment as followsSituation, that is, and by making the left linking part 34b of vibrationproof matrix 30 and the thickness of right linking part 34d be formed as being less than front linking part 34aAnd rear linking part 34c, make thus the spring constant of left and right directions be set as the numerical value of the spring constant that is less than fore-and-aft direction. To thisIn the second embodiment, will describe following situation, that is, and by form at vibrationproof matrix 130 through-hole section 134b,134d, the spring constant of left and right directions is set as the numerical value of the spring constant that is less than fore-and-aft direction. In addition, for the first enforcementThe part that scheme is identical, is used identical Reference numeral and omits following explanation.

Figure 14 is the stereogram that the antihunting device 101 of the second embodiment is shown, Figure 15 is the master that antihunting device 101 is shownView, Figure 16 is the side view that antihunting device 101 is shown, and Figure 17 is the top view that antihunting device 101 is shown, and Figure 18 illustrates edgeThe cutaway view of the antihunting device 101 of the XVIII-XVIII line of Figure 17. Antihunting device 101 possesses: upside installation component 110, itsBe installed on power set PP side; Downside installation component 20, it is installed on vehicle body frames BF side; And vibrationproof matrix 130, its intervention is establishedPut between upside installation component 110 and downside installation component 20.

As shown in figure 14, upside installation component 110 is, by fore-and-aft direction in the time overlooking compared with long and left and right directions is shorter,The roughly sheet material of rectangular shape and the member that forms, this upside installation component 110 possesses: board 111 is installed, and it is large when overlookingCausing rectangular recess forms; Upper limiting unit 112, it is connected to form around board 111 is installed, and more towards front and backTo (arrow F-B direction) more up-wards inclination; Flat condition upper facial 113, it is connected to form the front and back in upper limiting unit 112To, and extend in the horizontal direction; Upper carrier 114, itself and upper facial 113 be connected to form, and more towards fore-and-aft direction more underInclination is fallen; And the upper extension board 115 of flat condition, its front and back at upper carrier 114 are connected to form, and prolong towards fore-and-aft directionStretch. Be formed through and be useful on the 111a of hole portion that inserts the axis-shaped component B such as bolt in the approximate center that board 111 is installed. VibrationproofMatrix 130 is unbondedly to get involved the member being arranged between upside installation component 110 and downside installation component 20, vibrationproof baseBody 130 possesses the extension 133 of the impact for cushioning the load of beating.

As shown in figure 15, upper extension board 115 is less than the left and right directions width of downward-extension board 26 with the main apparent time of its widthMode form. The width of extension 133 is set the width that is less than downward-extension board 26 for, and the width of upper extension board 115 is establishedDetermine into the width (with reference to Figure 17) that is less than extension 133. In addition, as shown in figure 16, the fore-and-aft direction (arrow of downward-extension board 26F-B direction) length setting become to be greater than the length of fore-and-aft direction of the upper extension board 115 of upside installation component 110, extension133 are positioned at the below of extension board 115. Further, with regard to vibrationproof matrix 130, retain front linking part 134a and rear companyKnot 134c and become left and right through-hole section 134b, the 134d of cavity, is formed at upside installation component 110 and downside installation component 20Between position.

As shown in figure 18, vibrationproof matrix 130 possesses bottom 131 and upper end 135 and for linking their linkPortion 134, and be formed with intercommunicating pore 130a in the approximate center of vibrationproof matrix 130, described intercommunicating pore 130a has roughly fourThe inner peripheral surface of angle tubular, and for being communicated with bottom 131 and upper end 135 at above-below direction. The upper end of vibrationproof matrix 130135 are connected to upside installation component 110, and bottom 131 is connected to downside installation component 20.

The upper limiting unit 112 of upside installation component 110 is more towards more up-wards inclination and being connected to form in the above of fore-and-aft directionPortion 113, the upper carrier 114 that the fore-and-aft direction of portion 113 is connected to form the in the above inclination that more more declines towards front and back. Thus, ifCompression load loads on vibrationproof matrix 130 via upside installation component 110, and the upper end 135 of vibrationproof matrix 130 is in left and rightDirection is subject to the restriction of limiting unit 112 and upper carrier 114, and face 113 restriction on above-below direction is subject to. Its knotReally, can prevent that the position of the upper end 135 of vibrationproof matrix 130 from departing from, therefore, compression load can be pacified via upsideFill member 110 and load on vibrationproof matrix 130. In addition, with regard to vibrationproof matrix 130, due to bear in after have a down dip the 25c's of portionFront extension 132c and rear linking part 134c are connected to form, and therefore, can increase the volume of the fore-and-aft direction of vibrationproof matrix 130,And guarantee the spring constant of fore-and-aft direction.

In addition, with regard to vibrationproof matrix 130, in the position, left and right of front linking part 134a and rear linking part 134c, i.e. upper endPosition between portion 135 (end, upper right 135d etc.) and extension 133 (right extension 133d etc.), be formed with through-hole section 134b,134d. Because the left and right place at vibrationproof matrix 130 is formed with through-hole section 134b, 134d, therefore with the spring constant of fore-and-aft directionCompare, can reduce the spring constant of left and right directions.

With regard to vibrationproof matrix 130, at the inner peripheral surface of intercommunicating pore 130a, below more close than through-hole section 134b, 134dPosition, in bottom 23 (rear bottom 23c, right bottom 23d etc.) and upper wall portions 24 (rear upper wall portions 24c, right upper wall portions 24d etc.)Horizontal level, be formed with the recess 138 across the whole circumference of intercommunicating pore 130a. Owing to being formed with recess 138, therefore vibrationproofMatrix 130 is by the loading of the compression load of above-below direction, with to upper wall portions 24 (rear upper wall portions 24c, right upper wall portions 24d etc.) sideThe mode of expansion is out of shape. Thus, with the first embodiment in the same manner, can prevent that vibrationproof matrix 130 is from downside installation component 20Separate.

In addition, with regard to vibrationproof matrix 130, extend and be provided with downward-extension setting unit 137 downwards from bottom 131, andAnd be provided with the laterally extending setting unit of extending to horizontal direction outside from the top of the whole circumference of downward-extension setting unit 137137a. If the downward-extension setting unit 137 of vibrationproof matrix 130 and laterally extending setting unit 137a are inserted in the mode of strainIn the lower through hole 20a of downside installation component 20, the top of laterally extending setting unit 137a is positioned at downside installation component 20The outside of lower wall portion 21. Its result, downside installation component 20 is fixed on vibrationproof matrix 130 by laterally extending setting unit 137a.In addition, with regard to laterally extending setting unit 137a, because the groove 137b of the bottom for intercalation lower wall portion 21 is wholeCircumferencial direction forms, and therefore can make downside installation component 20 be difficult to come off from vibrationproof matrix 130.

Figure 19 is the stereogram that vibrationproof matrix 130 is shown, Figure 20 is the front view that vibrationproof matrix 130 is shown, Figure 21 showsGo out the side view of vibrationproof matrix 130, Figure 22 is the top view that vibrationproof matrix 130 is shown, Figure 23 illustrates along Figure 22The cutaway view of the vibrationproof matrix 130 of XXIII-XXIII line. Vibrationproof matrix 130 is as linking with upside coupling member 110 and downsideOther different members of member 20 independently carry out vulcanization forming, and vibrationproof matrix 130 is unbondedly got involved and is arranged at upside link structureBetween part 110 and downside coupling member 20.

As shown in Figure 20 and Figure 21, through-hole section 134b, 134d make the left and right directions of vibrationproof matrix 130 be formed as cavity. SeparatelyOutward, as shown in figure 22, inserting hole 130a has in the time overlooking the roughly inner peripheral surface of rectangular shape, and this inserting hole 130a is at vibrationproof baseThe whole above-below direction of body 130 is formed through. Thus, can make the bullet of the left and right directions (arrow R-L direction) of antihunting device 101Spring constant is different from the spring constant of fore-and-aft direction (arrow F-B direction).

In addition, due to vibrationproof matrix 130 other members different from upside installation component 110 and downside installation component 20Carry out vulcanization forming, therefore, can improve the design freedom of the sulfurizing mould for making vibrationproof matrix 130 vulcanization formings. ByThis, as shown in figure 23, easily form recess 138 and through-hole section 134b, the 134d as undercutting at vibrationproof matrix 130.

The user of the using method of the antihunting device 101 of the second embodiment and the antihunting device 1 of the first embodimentMethod is identical, therefore omits following explanation. According to antihunting device 101, with the antihunting device 1 of the first embodiment in the same manner, pass throughForm recess 138 at vibrationproof matrix 130, can prevent that vibrationproof matrix 130 from departing from respect to downside installation component 20. SeparatelyOwing to being formed with through-hole section 134b, the 134d of the left and right directions that runs through vibrationproof matrix 130, therefore, can make left and right directions outward,Spring constant set the spring constant that is less than fore-and-aft direction for.

Then,, with reference to Figure 24 to Figure 33, the 3rd embodiment is described. In the first embodiment and the second enforcement sideIn case, following situation is illustrated, that is, and by making the left linking part 34b of vibrationproof matrix 30 and the thickness of right linking part 34dBe formed as being less than front linking part 34a and rear linking part 34c, or run through the left and right directions of vibrationproof matrix 130 by formationThrough-hole section 134b, 134d, make the spring constant of left and right directions set the spring constant that is less than fore-and-aft direction for. To this, the 3rdIn embodiment, following situation is described, that is, form protuberance 240 by the left and right directions at vibrationproof matrix 230, by left and rightThe spring constant of direction is set the spring constant that is greater than fore-and-aft direction for. In addition, for the part identical with the first embodiment,Use identical Reference numeral and omit following explanation.
