Description
Technical field
The utility model belongs to the main damping of electric vacuum pump damping appliance technology more particularly to a kind of damping device
Device mechanism.
Background technology
New-energy automobile is increasingly paid attention to, but since inside electric vacuum pump, to move back and forth, radial direction can be caused
Out-of-balance force, so that vibrations can be caused.And there is electric vacuum pump under the severe inertia impact operating mode of vehicle traveling and come off.Base
In continuous improvement of the current new-energy automobile to vehicle NVH performance requirements, and the considerations of automobile reliability, security.Special open is sent out
A electric vacuum pump shock-damping structure for being suitable for moving back and forth.There is defects for current damping：When rigidity compared with
Greatly, it is impossible to reach preferable damping effect；Second is that assembling trouble, mechanism are unreasonable.
The content of the invention
It the purpose of this utility model is that solve the problems, such as techniques discussed above, provides a kind of rational in infrastructure, can reduce
The rigidity of damper, is conducive to damping and assembling, is conducive to absorb impact energy, reaches the damping device of preferable shockproof effect
Main damper mechanism, technical solution is as follows：
The main damper mechanism of damping device, which is characterized in that including main damper, offered on the main damper
Cavity is provided with two opposed dislocation equalization vestibules on the main damper, is set in the both ends of the surface of the main damper
There is step.
Preferred embodiment is that the cavity is hexagon cavity.
Preferred embodiment is to be opened up at the following side of the main damper fluted.
Preferred embodiment is that the middle of the side of the main damper is provided with ring rib.
The main damper mechanism of damping device provided by the utility model, when in use, the setting of main damper is
In order to improve the cushioning ability of entire vacuum pump so that impact energy is effectively absorbed.Main shock absorber design, using silicon rubber
Sulfidization molding, both ends of the surface design step are realized when main damper is packed into the cup-shaped cavity of cupuliform support plate, end face Stiffness Drop
It is low, be conducive to damping and assembling, outside diameter and cup-shaped cavity are in interference fit, during assembling, apply a small amount of water, can be easily assembled；
Six sides of hexagon cavity are interference fitted with the outside diameter of fixed pin and fixing piece, and six corners are in gap state, are conducive to rubber
The deformation of glue part absorbs impact energy, reaches damping purpose；Two opposed dislocation equalization vestibules are designed, the radial direction for reducing product is firm
Degree, reaches good damping performance.
The groove and ring rib of the utility model can enable main damper to be preferably mounted on vacuum pump so that
Main damper is not easily to fall off in use.
The beneficial effects of the utility model are：It is rational in infrastructure, the rigidity of damper can be reduced, is conducive to damping and dress
Match somebody with somebody, be conducive to absorb impact energy, reach the damping device of preferable shockproof effect.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to Fig. 1 specific illustrative embodiments：
The main damper mechanism of damping device including main damper 1, offers cavity 2, institute on the main damper 1
Two opposed dislocation equalization vestibules 3 are provided on the main damper 1 stated, platform is provided in the both ends of the surface of the main damper 1
Rank 4.
Preferred embodiment is that the cavity is hexagon cavity.
Preferred embodiment is to open up fluted 5 at the following side of the main damper.
Preferred embodiment is that the middle of the side of the main damper is provided with ring rib 6.
Main shock absorber design, is molded using silicon rubber vulcanization, and both ends of the surface design step is realized and is packed into cup in main damper
When in the cup-shaped cavity of shape support plate, end face rigidity reduces, and is conducive to damping and assembling, and outside diameter is in interference fit with cup-shaped cavity,
During assembling, a small amount of water is applied, can be easily assembled；Six sides of hexagon cavity and the outside diameter interference of fixed pin and fixing piece are matched somebody with somebody
It closes, six corners are in gap state, are conducive to rubber parts deformation and absorb impact energy, reach damping purpose；Design two opposed mistakes
The impartial vestibule in position, reduces the radial rigidity of product, reaches good damping performance.
At work, the impact endurance test shock radially generated, by two main dampers, can effectively absorb impact energy, shock insulation rate
More than 95% can be reached.
