Description
Technical field
The utility model is related to automobile bushing technical field, more particularly to a kind of vehicle body hydraulic bushing.
Background technology
In auto industry production process at this stage, for automobile chassis shaking when driving is greatly reduced
Dynamic, how please understanding for chassis and suspension is changed into flexible and links, wherein, topmost flexible on-link mode (OLM) is by suspended portion
The end attachment of part arranges rubber bushing, and existing rubber bushing mostly is pure glue bushing, and pure glue bushing has cheap, system
The advantages of making process is simple, take up room little, but Gao Qiandu, high resistant can not be met under low frequency, the working condition of large amplitude
The requirement of the damping noise reduction of Buddhist nun, is this it is proposed that a kind of vehicle body hydraulic bushing, solves the above problems.
Utility model content
The purpose of this utility model is and a kind of vehicle body hydraulic pressure lining for proposing in order to solve shortcoming present in prior art
Set.
To achieve these goals, the utility model employs following technical scheme：
A kind of vehicle body hydraulic bushing, including cavity spacing block, shell, hydraulic chamber, rubber bodies, aluminium alloy inner frame,
Fixed mount and damping hole, the inside of the shell are provided with rubber bodies and aluminium alloy inner frame, and rubber bodies are located at shell and aluminium alloy
Between inner frame, aluminium alloy inner frame is provided with two fixed mounts, and the inside of rubber bodies is provided with hydraulic chamber, hydraulic chamber
Inside be provided with cavity spacing block, cavity spacing block is provided with damping hole.
Preferably, the aluminium alloy inner frame and fixed mount are integral type structure, and fixed mount is on aluminium alloy inner frame
It is symmetrical arranged, the longitudinal cross-section of fixed mount is L-shaped.
Preferably, the rubber bodies are used for surrounding the upper and lower side of hydraulic chamber and are arcuate structure.
Preferably, damping hole is uniformly provided with the cavity spacing block.
Preferably, through hole is provided with the fixed mount, and through hole is equal in magnitude.
Preferably, the rubber bodies and the sulfuration of aluminium alloy inner frame are integral, and in the hydraulic chamber inside rubber bodies
It is provided with damping fluid.
The beneficial effects of the utility model：When damping fluid is subject to external force pressure, damping fluid is from the side of fluid working cavity
Opposite side is entered by the damping hole on cavity spacing block, with good elastic reaction force, when hydraulic bushing is subject in radial direction
When low frequency, large amplitude are encouraged, it can axially or radially providing larger damping, so as to effectively isolate road surface excitation,
The shake of wheel when the imbalance of tire and braking, on the outside of which and inside be provided with shell and aluminium alloy inner frame to increased which firm
Property, it is not easy to deform in the presence of external force, while increasing rubber bodies and aluminium alloy inner frame degree of fixation by fixed mount, prevent
Rubber bodies voluntary activity.
