Boundary's air, it is to avoid guide piston produces back pressure when retracting, and reduces energy loss, improves gas energy storage efficiency.
3 but due between guide cylinder and buffer housing be provided with alignment pin, alignment pin serve prevent guide cylinder motion
During rotate and cause fuel feed hole to misplace, to ensure that the fuel feed hole on guide cylinder can connect piston guide chamber and oil storage all the time
Groove.
4th, because the rear and front end of piston guide chamber is respectively equipped with front seal and rear seal, by centre pilot axle with delaying
Device housing is rushed to separate by front seal and rear seal, and front seal and rear seal all use elastomeric material, can be with
Buffer the vibration of centre pilot axle, it is to avoid buffer housing receives the impact of centre pilot axle and vibrates aggravation.
5th, due to being provided with a guide pad in external part, guide pad is fixed on the inwall of spacer, be provided with guide pad with
The pilot hole that centre pilot axle is adapted, on the one hand, guide pad serves supporting role, improves the intensity of spacer, the opposing party
Face, guide pad serves guide effect.
6th, due to being provided with cushion pad between hinged set and buffer housing, cushion pad is set in centre pilot shaft extension and goes out buffering
The part of device housing, one side cushion pad can stop that dust is attached on centre pilot axle, be effectively protected in buffer
The potted component of oil sealing, rubber ring etc., extends the service life of damper of the present invention, on the other hand, when the center axis of guide is returned
During contracting, hinged set and buffer housing have been separated, impulsive force is reduced.
7th, due to being provided with compression spring between hinged set and buffer housing, secondary buffer serves cushioning effect, from
And when reducing buffer damping lubricating oil oil pressure, reduce the pressure oscillation of oil lubrication system.
8th, the power of lubricating oil system is provided by gas energy storage chamber, can also supply and discharge to other oil sites, by impulsive force,
Save lubricating power, it is not necessary to frequently enable grease pump and lubrication can be achieved, have very important significance.
As described above, the invention provides a kind of damping of electric vehicles device assembly, the damping of electric vehicles device assembly passes through only
Special structure design and mutual cooperation, so as to achieve many advantageous effects, have good answer in auto industry field
With prospect and industrial production potential, it may have good promotional value.
