Have a direct impact, mounting structure becomes more diversified also with increasing for vehicle.In current mounting structure assembly, trailing arm
Easily there is the risk being ejected, security is low.
The content of the invention
The utility model is intended at least solve one of technical problem existing in the prior art.For this reason, the utility model carries
For a kind of sleeved rubber mounting structure, it is therefore an objective to avoid trailing arm from being ejected, improve security.
To achieve these goals, the technical solution that the utility model is taken is:
A kind of sleeved rubber mounting structure, including trailing arm, rubber spring assembly and skeleton, the skeleton and rubber spring
Assembly by be interference fitted connect, the rubber spring assembly include set gradually from inside to outside main spring core pipe, main spring rubber
With main spring outer tube, the main spring core pipe compresses locking connection with trailing arm.
The auxiliary stand and footing that the skeleton includes outer tube, is fixedly connected with outer tube, the outer tube interference set
It is connected on the outside of rubber spring assembly.
The skeleton is sheet metal structural skeleton.
The auxiliary stand is fixedly connected with outer tube by welding with footing.
The main spring rubber is compressed spacing by undergauge with main spring outer tube.
The cut-off of the undergauge is 0.5-2mm.
The main spring outer tube, main spring rubber and main spring core pipe are an integral molding structure.
The trailing arm is cast aluminium trailing arm.
The beneficial effects of the utility model:The utility model can effectively evade trailing arm easily quilt by core pipe structure optimization
Eject risk, lifting system reliability.Being reached by undergauge selects the elastomeric material compared with soft to meet load-carrying properties, realizes high
Frequently relatively low dynamic stiffness, improves NVH performances;It can realize that Z+ to spacing gap≤0, reduces main spring rubber tension row by undergauge
Journey, lifts endurance quality;In addition, this mounting structure three-way rigidity can be carried out design well, adjust, to reach three-dimensional all
There is good vibration damping capacity;Each direction possesses rational spacing form, can be good at limiting the excessive of power assembly
Displacement, reduces passenger compartment inner sense and is impacted be subject to power assembly, improve the service life of mounting structure.Mounting structure can be lifted
Fatigue strength, evaded rubber cracking risk, improved security performance;The anti-vibration performance of suspension can be lifted again, it is permanent to vehicle
NVH performances have obvious benefit.The sleeved rubber mounting structure of the utility model can realize the compact letter of rubber suspension structure
Single, overall structure uniform force is reasonable, possesses preferable fatigue properties, and all directions have vibration decay and spacing work well
With.

Embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation, it is therefore an objective to help design of the those skilled in the art to the utility model, technical solution have it is more complete, accurate and
Deep understanding, and contribute to its implementation.
As shown in Figures 1 to 5, the utility model is specifically related to a kind of sleeved rubber mounting structure, including trailing arm 1, rubber
The main spring assembly of glue and skeleton, skeleton are connected with rubber spring assembly by being interference fitted, and rubber spring assembly is included from inside to outside
Main spring core pipe 2, main spring rubber 3 and the main spring outer tube 4 set gradually, main spring core pipe 3 compress locking connection with trailing arm 1.Vulcanizing
Before technique, trailing arm 1 is connected with main spring core pipe 3 by compressing locking technique so that core pipe structure is without embodying press-in angle;Can be with
Avoid the risk ejected during the work time by axial force when larger.
Main spring outer tube 4, main spring rubber 3 and main spring core pipe 2 are integrally formed molding structure by sulfuration process.Rubber spring is total
As principal vibration attenuation module, pass through rational rigidity and spacing design so that vehicle possesses a preferable NVH
Can, power assembly is maintained within the scope of rational moving displacement.Skeleton is with rubber spring assembly preferably using circular bushing shape
Formula interference fit connection.Trailing arm is preferably cast aluminium trailing arm.
The auxiliary stand 6 and footing 7 that skeleton includes outer tube 5, is fixedly connected with outer tube 5,5 interference of outer tube are socketed on
On the outside of rubber spring assembly.Skeleton is preferably sheet metal structural skeleton.Auxiliary stand and footing by welding with outer tube
It is fixedly connected.Mounting structure realizes enough intensity and mode to welded framework for this, possesses enough fatigue properties, ensures skeleton
It is not broken under various operating modes;In addition, skeleton is interference fitted the position limiting structure to be formed to moving always with rubber spring assembly
The displacement in three directions has control, avoids dynamic always excessive in the displacement of front deck, and dynamic interference occurs with its periphery member, it occurs
His unpredictable risk.
Main spring rubber 3 is compressed spacing by diameter reducing process with main spring outer tube 4.After the shaping of rubber spring assembly, pass through contracting
Footpath technique makes main spring rubber 3 reach press mounting dimension;Rubber spring assembly and welded framework were passed through finally by press-loading process
It is full of mating connection, forms rubber mounting finished product.Pass through diameter reducing process, it is possible to achieve main spring rubber 3 forms precompressed and Z+ to limit
Interdigit gap≤0;This technique makes winner's spring rubber on the premise of structure Static stiffness is met, selects the relatively low elastomeric material of hardness,
Dynamic stiffness is reduced, lifts NVH performances;At the same time spacing gap≤0 of Z+, can to avoid rubber spring during the work time because stroke compared with
Greatly, there are the failure risks such as rubber drawing crack;Diameter reducing process refers to design requirement and sulfuration process when choosing cut-off, and one
As choose 0.5~2mm.
By the rational design of the moulding process and main spring core pipe of rubber spring assembly, trailing arm pop-up is avoided well
Risk, the fatigue properties for effectively raising main spring rubber and system NVH performances;The utility model can be according to NVH performance need
Seek the three-way rigidity value of effective adjustment mounting structure;Can be according to the subjective assessment demands of different operating modes, dynamic total displacement control
Demand reasonably designs position limiting structure.
The utility model is exemplarily described above in association with attached drawing.Obviously, the utility model implements not
Limited by aforesaid way.As long as employ the various unsubstantialities that the methodology of the utility model and technical solution carry out
Improvement;Or it is not improved, above-mentioned design and technical solution by the utility model directly apply to other occasions, at this
Within the protection domain of utility model.
