Preferably, several grooves are radially offered along bushing on the lug boss.

Further, the yielding rubber portion includes the first yielding rubber and the second yielding rubber；First yielding rubber Excircle is fixedly connected with the inner periphery of outer tube, and the inner periphery diameter of the first yielding rubber is gradually become by export-oriented end to inward end Greatly, inner periphery diffuses into trumpet type；The inner periphery of second yielding rubber is fixedly connected with the excircle of inner tube, the second buffering rubber The excircle diameter of glue is gradually become smaller by inward end to export-oriented end, and excircle converges pyramid type；First yielding rubber is nested In the outside of the second yielding rubber, the trumpet type inner periphery of the first yielding rubber and the pyramid type excircle of the second yielding rubber are tight It is close to be combined together；First yielding rubber offers circumferential annular groove on the end face of nearly inward end.

Preferably, the concave surface of the annular groove is circular arc type.

Still further, the bushing further includes a block, the block covers on the outside of inner tube and buffers rubber with second The end face of nearly inward end is fixedly connected on glue.

The utility model compared with the prior art, is provided on the end face at bushing extroversion end with lug boss and recessed portion End face yielding rubber to improve the shock resistance buffer capacity of its end face, and yielding rubber portion is set as including first delaying The assembly of rubber and the second yielding rubber is rushed, and offers circumferential ring on the end face of nearly inward end in the first yielding rubber Connected in star enables suspension bushes more effectively defeated and dispersed and disappears so that the utility model obtains the effect of better axial buffer Impact except external energy to suspension, to make automobile at runtime, the motion state of suspension system is more stable, it is handling more It is good.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the automotive suspension bushing of the prior art；

Fig. 2 is the end elevation view of the routed energy type automotive suspension bushing of the utility model；

Fig. 3 is the structural schematic diagram of the utility model.

In figure: 1 outer tube, 2 yielding rubber portions, 21 first yielding rubbers, 22 second yielding rubbers, 23 annular grooves, in 3 Pipe, 4 export-oriented ends, 5 inward ends, 6 outer end faces, 7 end face yielding rubbers, 71 lug bosses, 72 recessed portions, 73 grooves, 8 blocks.

Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments:

Referring to figs. 2 and 3, a kind of energy type automotive suspension bushing of bursting, including inner tube 3, outer tube 1 and buffering rubber section 2.It is interior The excircle of pipe 3 is fixedly connected with the inner periphery in yielding rubber portion 2, and preferred rubber vulcanization combination is fixed, and can be protected in this way Card is connected firmly not tearable；The excircle in yielding rubber portion 2 is fixedly connected with the inner periphery of outer tube 1, also, it is preferred that rubber Vulcanization combination is fixed.Wherein outer tube 1 can be metal material or plastic material；Inner tube 3 can be metal material, preferably Steel or aluminum alloy material.

One end of the bushing is export-oriented end 4, and the other end is inward end 5；1 end face of outer tube at the extroversion end 4 is set It is equipped with flange, to form outer end face 6, the bushing further includes end face yielding rubber 7, and the covering of end face yielding rubber 7 is simultaneously It is fixed on outer end face 6, the surface of end face yielding rubber 7 includes two lug bosses 71 and two recessed portions 72, described two convex Portion 71 and two recessed portions 72 are played to be distributed both with respect to bushing central symmetry.Preferably, it is radially opened on lug boss 71 along bushing Equipped with several grooves 73.

The logical interference fit of the routed energy type automotive suspension bushing of the utility model is pressed into the casing of torsion beam suspension, is then used Bolt passes through the inner tube 3 of bushing and body support and fastens, so that automobile torsion beam suspension be linked together with body support. The flange of 1 end face of outer tube at bushing extroversion end 4 can limit axial movement of the bushing in torsion beam suspension casing.End face is slow The setting for rushing 7 surface upper projecting portion 71 of rubber and recessed portion 72 enables the lateral force F of bushing effectively buffering automobile suspension to lining The impact of the outer end face 5 of set influences, and when there is lateral force F effect, end face yielding rubber 7 can effectively deform energy-absorbing, thus slow Offset shock resistance.And several grooves 73 opened up on lug boss 71 can then effectively reduce the noise that friction generates, meanwhile, also Reduce rubber extruded abrasion, improves anti-fatigue performance.

Referring to Fig. 3, in order to obtain the effect of better axial buffer, yielding rubber portion 2 be can be including the first buffering rubber The assembly of glue 21 and the second yielding rubber 22, wherein the inner periphery of the excircle and outer tube 1 of the first yielding rubber 21 is fixed Connection, the inner periphery of the second yielding rubber 22 are fixedly connected with the excircle of inner tube 3.The inner periphery diameter of first yielding rubber 21 Become larger by export-oriented end 4 to inward end 5, inner periphery diffuses into trumpet type, the excircle diameter of the second yielding rubber 22 by Inward end 5 to export-oriented end 4 gradually becomes smaller, and excircle converges pyramid type, and the first yielding rubber 21 is nested in the second buffering rubber The outside of glue 22, the trumpet type inner periphery of the first yielding rubber 21 and the pyramid type excircle of the second yielding rubber 22 are combined closely Together.First yielding rubber 21 offers circumferential annular groove 23 on the end face of nearly inward end 5, it is preferable that the ring The concave surface of connected in star 23 is circular arc type.The setting of annular groove can make yielding rubber portion 2 have deformation in responsive to axial force The space of yielding.So, enable suspension bushes more effectively defeated and dispersed external energy, to more preferably eliminate external energy pair The impact of suspension.

It can also include a block 8, the preferred plastic material of block 8, institute on the bushing of the utility model referring to Fig. 3 8 sets of block are stated in 3 outside of inner tube and is fixedly connected with the end face of inward end 5 close on the second yielding rubber 22, it can be using bonding Mode be fixedly connected.The setting of block 8 can make bushing increase axial carrying capacity.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the protection scope of the utility model, Therefore, any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention, should be included in Within the protection scope of the utility model.
