Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of suspension shock-absorber of double stiffness structures, including midfoot support plate 2 and supporting sleeve 6, middle part
2 top of support plate is connected with upper junction plate 1, lower section is connected with lower connecting plate 3, is equipped between supporting sleeve 6 and midfoot support plate 2
Leather cup 12,2 end of midfoot support plate are connected with upper yielding rubber 9, lower yielding rubber 11 respectively, upper 9 other end of yielding rubber with
Upper limit plate 5 is connected, and lower 11 other end of yielding rubber is connected with lower limiting board 13, and leather cup 12 is equipped with inertia channel 7, and inertia is logical
Inlet 16 is equipped with below road 7, top is equipped with liquid outlet 17, the cavity between leather cup 12 and upper limit plate 5, upper yielding rubber 9
It forms and pushes liquid chamber 14, the cavity between leather cup 12 and lower limiting board 13, lower yielding rubber 11 forms hydraulic fluid room 15.Into
Liquid mouth 16, top misplace equipped with liquid outlet 17, and damping fluid can push liquid chamber 14, liquid outlet 17, inertia channel 7, inlet
It is flowed between 16 and upper hydraulic fluid room 15.
Lower connecting plate 3 is equipped with carrying rubber 10.It is set between the midfoot support plate 2, upper junction plate 1 and lower connecting plate 3
There is connection bolt 4.
The utility model belongs to support assembly on decoupling type suspension shock-absorber, carrying 10 place position of rubber installation bearing and
Suspension shock-absorber spring, major function are bearing vehicle body weight, and internal upper yielding rubber 9 and lower yielding rubber 11 are mainly to subtract
Shake device vibration isolation position, and leather cup 12 hinders structure using inertia channel and liquid, when small deformation on yielding rubber 9 and lower buffering rubber
11 position of glue as main vibration isolation function, when large deformation on yielding rubber 9 and lower 11 malformation of yielding rubber compression
Upper hydraulic fluid room 15 or push liquid chamber 14 volume, upper hydraulic fluid room 15 or push liquid chamber 14 in liquid need by inlet 16,
Inertia channel 7 and liquid outlet 17 are flowed.The speed and the sectional area of inertia channel, length of damping fluid flowing can be effective
Damping is improved, to provide higher rigidity in large deformation to support.Because of the compression damping of damper and recovery damping
Difference, compression damping power is small, and TOP MOUNT forward direction rigidity needs are smaller, preferably carries out vibration decaying, so positive rubber
Support stiffness is higher, and negative sense damping force is larger, and the rigidity of negative sense needs height, is effectively limited and resisted the deformation of rubber,
Upper and lower yielding rubber, which carries out production using different rubber hardness, may be implemented this double stiffness structure, can be subtracted with effective solution
The device that shakes impacts and lower jump bring NVH problem.
