Description
Technical field
The present invention relates to a kind of damper, more particularly to a kind of damping of electric vehicles device belongs to damper technical field.
Background technology
In the automotive industry, in order to make the vibration of vehicle frame and vehicle body decay rapidly, improve electric vehicle traveling ride comfort and
Comfort is typically equipped with damper in the suspension system of electric vehicle.Damper is the rapid wear accessory during electric vehicle use,
And quality, the quality of performance of its working condition, the service life of the stationarity and other parts of electric vehicle traveling will be directly affected.Base
In such consideration, damper should be made often in good working order.
The operation principle of damper be by inhibit spring shock-absorbing after rebound when concussion and from the impact on road surface, be used for
Contend with the twisting vibration (i.e. the impact force of bent axle subject cylinder igniting and the phenomenon that twist) of bent axle.In suspension systems, due to bullet
Property element be hit generation vibration, be installed in parallel damper with elastic element to improve electric vehicle ride performance, in suspension, from
And the vibration that decayed.
In addition, some dampers in order to increase its steering capability, all use centre pilot axis, to increase the steady of its operation
It is qualitative.But the friction between centre pilot axis and shell is larger, it is another although on the one hand absorbing partial vibration energy
Aspect damping effect is undesirable, once centre pilot axis forms rigid contact with shell, will transfer vibrations on shell,
It is poor so as to cause damping effect.
Currently, people have carried out a large amount of further investigation to damping of electric vehicles device, and achieve some achievements, such as：

Still more preferably, for the set-up mode of the compressed spring, the applicant has also carried out further grinding
Study carefully improvement, to devise a kind of novel compressed spring set-up mode, specially：Technical side as one preferred
The specific set-up mode of case, the compressed spring is as follows：The first spring base, the buffer are installed in the hinged set
Be installed with second spring seat on shell, the second spring cover for seat is loaded on the external part, the compressed spring clamp in
Between first spring base and the second spring seat.
By structure design so, the compressed spring can secondary buffer play cushioning effect, to reduce
The oil pressure of lubricating oil when buffer damping, reduces the pressure oscillation of oil lubrication system.
Certainly, the compressed spring can also be not provided between the hinged set and the buffer housing, at this time without
Non- damping effect is in a slight decrease and the oil pressure of lubricating oil is all increases.It is further to improve that the compressed spring, which is arranged,
And improvement.
As described above, the present invention provides a kind of damping of electric vehicles device, the damping of electric vehicles device passes through unique structure
Design and mutual cooperation, to achieve many advantageous effects, such as：
1, due to being provided with resetting spring associated with centre pilot axis and gas energy storage chamber, when hinged set is impacted
When, centre pilot axis retraction, compression reseting spring eliminates partial vibration, and with the retraction of centre pilot axis, compression piston
Air in compression piston compression chamber so that these compressed airs enter gas energy storage chamber by the second breather check valve, storage
Energy, and the process also improves damping effect simultaneously；Again due to being provided with guide cylinder so that work when buffer housing is processed
Skill becomes simpler and is easy, it is only necessary to the inner wall of guide cylinder finished, in use, guide cylinder abrasion
After can be individually replaced guide cylinder, without replacing entire buffer housing, greatly reduce maintenance cost, have fine
Use value.
2, since buffer housing is equipped with gas-permeable channels, can be connected between guide piston and buffer housing outer
Boundary's air, generates back pressure when guide piston being avoided to retract, reduce energy loss, improves gas energy storage efficiency.
3 but due between guide cylinder and buffer housing be equipped with positioning pin, positioning pin, which plays, prevents guide cylinder from moving
It rotates in the process and fuel feed hole is caused to misplace, to ensure that the fuel feed hole on guide cylinder can be connected to piston guide chamber and oil storage always
Slot.
4, since the rear and front end of piston guide chamber is respectively equipped with front seal and rear seal, by centre pilot axis and delay
It rushes device shell to separate by front seal and rear seal, and front seal and rear seal all use rubber material, it can be with
The vibration for buffering centre pilot axis, avoids buffer housing from receiving the impact of centre pilot axis and vibrate aggravation.
5, due to being equipped with a guide pad in external part, guide pad is fixed on the inner wall of spacer, be provided on guide pad with
The compatible pilot hole of centre pilot axis, on the one hand, guide pad plays supporting role, improves the intensity of spacer, another party
Face, guide pad play guiding role.
6, due to being equipped with cushion pad between hinged set and buffer housing, cushion pad is set in centre pilot axis and stretches out buffering
The part of device shell, one side cushion pad can stop that dust is attached on centre pilot axis, be effectively protected in buffer
The sealing element of oil sealing, rubber ring etc. extends the service life of damper of the present invention, on the other hand, when center guiding axis returns
When contracting, hinged set and buffer housing have been separated, has reduced impact force.
7, due to being equipped with compressed spring between hinged set and buffer housing, secondary buffer plays cushioning effect, from
And when reducing buffer damping lubricating oil oil pressure, reduce the pressure oscillation of oil lubrication system.
8, the power of lubricating oil system is provided by gas energy storage chamber, can also for draining into other oil sites, by impact force,
Save lubricating power, it is not necessary to frequently enable grease pump and lubrication can be realized, have very important significance.
As described above, the present invention provides a kind of damping of electric vehicles device, the damping of electric vehicles device passes through unique structure
Design and cooperate, to achieve many advantageous effects, have a good application prospect in auto industry field and
Industrial production potential, it may have good promotional value.
