Set rigidity adjustment usually makes multiple different-stiffness and the bushing of structure is verified respectively on real vehicle, needs to make many molds
And need repeated disassembled and assembled bushing, lead to cost to waste in a large number, and extend the cycle of design instruction.
Content of the invention
The purpose of the present invention is to propose to a kind of adjustable rear axle bushing of the rigidity for adjustment, this rear axle bushing manufacturer
Just, low cost, and there is larger stiffness tuning scope, can effectively reduce design cost and shorten the design cycle.
Rigidity for the adjustment adjustable rear axle bushing of the present invention from skeleton and removably with skeleton with rigidity
Regulating block is constituted, and described skeleton is provided with several accommodating holes, and the diameter parallel of accommodating hole is in the axial direction of skeleton；Described accommodating hole is extremely
Few one end open, for placing described stiffness tuning block.
It is not necessary to repeated disassembled and assembled rear axle bushing in rear axle bushing rigidity calibration procedures, varying number or not only need to be replaced
Can reach the adjustment scheme of multiple different-stiffness with the stiffness tuning block of material, the expense saved in calibration procedures became with the cycle
This.
Specifically, described skeleton is made up of the connecting portion of inner ring body, outer ring body and connection inner ring body and outer ring body, described
Cavity between inner ring body, outer ring body and connecting portion is described accommodating hole.Inner ring body, outer ring body not only can be adjusted rigidity of fixation
Locking nub it can also be ensured that between each position and rear axle of rear axle bushing contact friction force consistent.
Further, described stiffness tuning block and accommodating hole are interference fit, and the end of stiffness tuning block is provided with vertically
In the protuberance of stiffness tuning block axial direction, the protuberance of stiffness tuning block is exposed to outside accommodating hole.The mode of above-mentioned interference fit and
The protuberance of stiffness tuning block can make together with stiffness tuning block is stably bound in skeleton, to prevent stiffness tuning block from accommodating hole
Middle abjection.
Further, the section of described stiffness tuning block is fan arc, between so adjacent stiffness tuning block and different
Stiffness tuning block is identical to the pressure between skeleton, more meets the mechanical analyses situation of true bushing.
Further, this rear axle bushing also includes inner and outer tubes, and described skeleton is located between inner tube and outer tube, skeleton
It is interference fit with inner tube, outer tube.Inner and outer tubes coordinate, for spacing to skeleton, so that each position of skeleton is subject to
The active force being applied to rear axle all tends to identical.
Further, for ease of by outer tube, inner tube and Skeleton assembly together, one end of described outer tube is provided with outward bending
Flange；The length of said inner tube is more than the length of body and outer tube, and above-mentioned flange and longer inner tube can serve as stress
Position is to assemble inner and outer tubes.
Further, described inner ring body, outer ring body, inner tube, outer tube are to be arranged concentrically, and such stiffness tuning block is in skeleton
The stressing conditions in portion are all almost identical, and the rigidity Design with regard to rear axle bushing is also just more accurate.
Rigidity for the adjustment adjustable rear axle bushing design of the present invention stiffness tuning block that can dismount, using not
The stiffness tuning block combination of same hardness, material and quantity, you can to reach the rigidity adjustment demand of rear axle bushing, need not be simultaneously
Designing multiple rear axle bushings, thus shortening the development time of rear axle bushing, reducing development cost.

Specific embodiment
Below against accompanying drawing, by the description to embodiment, for example involved to the specific embodiment of the present invention is each
Mutual alignment between the shape of component, construction, each several part and annexation, the effect of each several part and operation principle etc. are made into one
The detailed description of step.
Embodiment 1:
As illustrated, the adjustable rear axle bushing of the rigidity for adjustment of the present embodiment is by inner tube 1, outer tube 2, skeleton 3 and removable
The stiffness tuning block 4 that dress ground is coordinated with skeleton 3 is constituted, and its middle skeleton 3 is located between inner tube 1 and outer tube 2, skeleton 3 and inner tube
1st, outer tube 2 is interference fit；One end of outer tube 2 is provided with the flange 21 of outward bending；The length of inner tube 1 is more than body and outer tube
2 length, in order to be assembled together outer tube 2, inner tube 1 and skeleton 3.
Skeleton 3 is made into integration by elastomeric material, specifically includes inner ring body 31, outer ring body 32 and connects inner ring body 31 and outer shroud
