Detailed description of the invention
As depicted in figs. 1 and 2, a kind of ratio of damping described in the utility model is at the uniform velocity pressed into and meets the strongest antivibrator,
Including cylinder body 1, piston 2, piston rod 3, end cover 4, it is provided with the fluid passage being through to the other end from one end on the piston 2
10, described piston 2 is arranged in the internal chamber of cylinder body 1, and the internal chamber of cylinder body 1 is divided into two chambers, described piston
Bar 3 connects with piston 2, and draws from the opening of cylinder body 1, arranges end cover 4 at this opening, for realizing this utility model
The purpose proposed, also includes spoiler 5 in antivibrator, and wherein spoiler 5 is covered on the end face relative with end cover 4,
And the port of convection cell passage 10 forms bridging effect, the end face of described piston 2 offers connection fluid passage 10 and choked flow
The damping flow channel 20 of sheet 5 place chamber.By above-mentioned design, when such hydraulic oil flows to spoiler 5 from fluid passage 10, meeting
Port in fluid passage 10 is by the stop of spoiler 5, then, turns and flows out from damping flow channel 20.Wherein, hydraulic oil flow
The fastest resistance by spoiler 5 of speed of body flowing is the biggest.Due to, when piston rod 3 is under by External Force Acting, will push away
Dynamic piston 2 moves, thus the hydraulic oil compressing side quickly flow to opposite side from side.Wherein, the biggest liquid of the effect of external force
The speed of force feed flowing is the fastest, due to, by stop and the effect of damping flow channel 20 of spoiler 5, external force its resistance the biggest is just
The biggest.After using technique scheme, damping flow channel 20 is designed to the annularity of cross-sectional area inconvenience, can just produce by antivibrator
Life is at the uniform velocity pressed into damping, and when running into bigger pressure, ratio of damping can be gradually increased the press-in that remains a constant speed simultaneously.Thus reach efficient
Cushioning effect, it is to avoid antivibrator is damaged.Simultaneously as damping flow channel 20 is opened in the end face of piston 2, it is not opened in
The inside of piston 2, the difficulty of its processing is relatively low, and the cost of processing also can decrease.
As shown in Figure 3 and Figure 4, the end face of described piston 2 was provided with oil groove 21, this one end crossing oil groove 21 and fluid passage
10 connect, and described spoiler 5 lid is put at the notch crossing oil groove 21 and exposed the other end of oil groove 21, described damping flow channel 20
Jointly enclosed by the cell wall of spoiler 5 with mistake oil groove 21 and formed.Described cross that oil groove 21 is linearly or arc or helical form.So
Directly offering cell body at end face, process the most simple and convenient than offering hole in inside, the cost of processing is relatively low.
On the basis of aforesaid, for the structure of further optimization piston, as shown in Figures 3 to 5, described piston 2 surface sets
Having the embedding slot 22 of annular, being provided with in described embedding slot 22 can be along sealing ring 6 in axial sliding of piston 2, described embedding slot
The side cell wall of 22 is provided with some the first mistake oil holes 23 leading to corresponding end face on piston 2, the bottom land of described embedding slot 22
Offer some axial grooves 24, the opposite side cell wall of described embedding slot 22 offers and leads to corresponding end face on piston 2
Second crosses oil hole 25, is further opened with some from embedding slot 22 on piston 2 surface that the opposite side cell wall of embedding slot 22 is corresponding
Leading to the axial groove 26 of corresponding end face, described damping flow channel 20 is crossed oil hole 25 with second and is connected；Described fluid passage 10 is by
One oil hole 23, groove 24, embedding slot 22, second oil hole 25, axial groove 26 excessively excessively collectively constitutes.Wherein, sealing ring 6 both sides
Face is respectively equipped with plane.As depicted in figs. 1 and 2, after piston 2 is loaded the internal chamber of cylinder body 1, chamber can be divided into left and right
Two chambers.When piston rod 3 shrinks, planar section close axial groove 26, now, hydraulic oil from left chamber through this first
Cross oil hole 23 to flow in embedding slot 22, be then passed through the second oil-through hole 25 and damp channel 20 and flow to the right chamber of piston 2
In.Owing to the second oil hole 25 oil mass excessively excessively is less, and by the stop of spoiler 5, thus realize the buffering effect of antivibrator.
When piston rod 3 stretches out, plane opens axial groove 26, hydraulic oil from right chamber in axial groove 26 flows to embedding slot 22,
Then cross in the chamber that oil hole 23 is flowed into left side respectively through groove 24, first, due to axial groove 26, groove 24 and first
The mistake oil mass crossing oil hole 23 is relatively big, and does not has any stop, antivibrator A normally to stretch out.
On the basis of aforesaid, for the structure of further optimal damping device, as depicted in figs. 1 and 2, it is being positioned at cylinder body 1
Piston rod 3 on be also respectively installed with Y-shaped ring 7, spring base 8, spring 9, wherein Y-shaped ring 7 be positioned at piston 2 and end cover 4 it
Between, described spring base 8 connects between Y-shaped ring 7 with end cover 4 and with Y-shaped ring 7, described spring 9 be positioned at spring base 8 with
Between end cover 4, and make the two ends overhead respectively of spring 9 on the medial surface and spring base 8 of end cover 4.Wherein, spring
The setting of 9 can strengthen the buffering effect of antivibrator further.
