Description
Technical field
The utility model relates to a kind of vibration damper, relates to a kind of sleeve formula cab air spring vibration damper specifically, belongs to auto parts machinery industry and field of rubber technology.
Background technique
More existing heavy trucks adopt traditional rigidity hydraulic type damping spring, and its weight ratio is heavier, complex structure, and assembly technology is also more loaded down with trivial details, and rigidity is large, and soundproof effect is poor, and the smoothness of truck in transportation process and travelling comfort also poor.Rigidity hydraulic type damping spring is unfavorable for the front overhang rear overhang shortening automobile, easily weares and teares with vehicle frame joint spring piot.Be not durable, replacement frequency is high.
Summary of the invention
It is simple that problem to be solved in the utility model is to provide a kind of structure, sleeve formula cab air spring vibration damper easy to assembly, it has variation rigidity characteristic, easily obtain lower natural frequency, the smoothness of truck in transportation process and travelling comfort can be improved, and the time in working life is long, and quality is little, soundproof effect is good.
In order to solve the problem, the utility model by the following technical solutions:
A kind of sleeve formula cab air spring vibration damper, comprise the piston cylinder and piston rod that are set in together, the outer cover of described piston cylinder and piston rod link position is equipped with the sealing tubular rubber parts that can fill gas, and described rubber parts can carry out axial stretching along piston cylinder and piston rod.
Below the further optimization of the utility model to such scheme:
The two ends of described rubber parts are connected with piston cylinder and rod seal respectively.
The effect that piston cylinder and piston rod play guiding at work and install, by forming extending amount between maximum height and minimum altitude, a damped motion in stroke range.
Further optimization: wherein one end of rubber parts is tightly connected by working of plastics and piston cylinder, and the other end is connected with rod seal by base.By the first seal ring sealing between base and piston rod.The effect that base plays fixing rubber parts and seals air-flow.
Further optimization: working of plastics is provided with can to the air inlet nozzle of insufflation gas in rubber parts, and air inlet nozzle connects PU suction tude, is the passage of air-flow.
Further optimization: the position near base on piston rod is installed with baffle plate.Spacing for carrying out position to base.
Further optimization: the position described piston rod being positioned at rubber parts is provided with buffer stopper, to vibration damper be compressed to extreme lower position time play a protective role.
First, rubber parts is a carrier storing air pressure, and rubber parts is by metal ring to base, and working of plastics carries out cissing by the mode of withholding, thus forms air pressure carrier part, and the mode that seal ring is equipped with by base and working of plastics in two ends seals air.Piston rod to fluctuate formation damped motion up and down relative to piston cylinder, and the inside is with cushion pad, and when vehicle load is compressed to product minimum altitude, cushion pad plays the effect of buffering, improves safety coefficient.Working of plastics is with inlet hole, and it at any time can supercharging ftercompction operation.
The utility model structure is simple, and easy for installation, long service life, replacement frequency is little.Truck soundproof effect in transportation process can be improved good, there is variation rigidity characteristic, good comfortable feel and smoothness are provided, each large accessory is played a protective role.
