Description
Technical field
The invention belongs to the main damper machine of electric vacuum pump damping appliance technology, more particularly to a kind of damping device
Structure.
Background technology
New-energy automobile is increasingly paid attention to, but due to 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 consideration of automobile reliability, security.JP is sent out
It is a to be applied to reciprocating electric vacuum pump shock-damping structure.There is defect for current damping：When rigidity compared with
Greatly, it is impossible to reach preferable damping effect；Second, assembling trouble, mechanism are unreasonable.
The content of the invention
It is an object of the invention to solve the problems, such as techniques discussed above, there is provided and it is a kind of rational in infrastructure, damping can be reduced
The rigidity of device, is advantageous to damping and assembling, is advantageous to apparatus with shock absorbing, reaches the master of the damping device of preferable shockproof effect
Damper mechanism, its technical scheme are as follows：
The main damper mechanism of damping device, it is characterised in that including main damper, opened up on described main damper free
Chamber, two opposed dislocation equalization vestibules are provided with described main damper, are provided with the both ends of the surface of described main damper
Step.
Preferred embodiment is that described cavity is hexagon cavity.
Preferred embodiment is to be opened up at the following side of described main damper fluted.
Preferred embodiment is that the middle of the sidepiece of described main damper is provided with ring rib.
The main damper mechanism of damping device provided by the invention, when in use, the setting of main damper be in order to
Improve the cushioning ability of whole vavuum pump so that impact energy is effectively absorbed.Main shock absorber design, using silicon rubber vulcanization
Shaping, its both ends of the surface design step, realize that end face rigidity reduces, and has when main damper loads in the cup-shaped cavity of cup support plate
Beneficial 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；Hexagon
Six sides of cavity are interference fitted with the outside diameter of steady pin and fixture, and six corners are in gap state, are advantageous to rubber parts change
Shape apparatus with shock absorbing, reach damping purpose；Two opposed dislocation equalization vestibules are designed, the radial rigidity of product is reduced, reaches
Good damping performance.
The groove and ring rib of the present invention can enable winner's damper preferably be arranged on vavuum pump so that master subtracts
It is difficult for drop-off in use to shake device.
The beneficial effects of the invention are as follows：It is rational in infrastructure, the rigidity of damper can be reduced, is advantageous to damping and assembling, is had
Beneficial to apparatus with shock absorbing, reach the damping device of preferable shockproof effect.
Brief description of the drawings
Fig. 1 is the schematic diagram of the present invention.
Embodiment
With reference to Fig. 1 specific illustrative embodiments：
The main damper mechanism of damping device, including main damper 1, cavity 2 is offered on described main damper 1, it is described
Two opposed dislocation equalization vestibules 3 are provided with main damper 1, step 4 is provided with the both ends of the surface of described main damper 1.
Preferred embodiment is that described cavity is hexagon cavity.
Preferred embodiment is to open up fluted 5 at the following side of described main damper.
Preferred embodiment is that the middle of the sidepiece of described main damper is provided with ring rib 6.
Main shock absorber design, is molded using silicon rubber vulcanization, its both ends of the surface design step, is realized and is loaded cup in main damper
When in the cup-shaped cavity of shape support plate, end face rigidity reduces, and is advantageous 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 steady pin and fixture are matched somebody with somebody
Close, six corners are in gap state, are advantageous to rubber parts deformation apparatus with shock absorbing, reach damping purpose；Design two opposed mistakes
The impartial vestibule in position, reduces the radial rigidity of product, reaches good damping performance.
At work, impact endurance test shock caused by radial direction, by two main dampers, can effective apparatus with shock absorbing, shock insulation rate
More than 95% can be reached.
