Abstract
The present invention relates to machinery spare and accessory parts technical field, particularly relate to a kind of strong sealing staggered piston ring of automobile-used damping.The technical solution used in the present invention is: a kind of strong sealing staggered piston ring of automobile-used damping, including the first combination ring bank and the second combination ring bank, described first combination ring bank is provided with boss structure, described second combination ring bank is provided with groove structure, described boss structure and described groove structure have two planes that contact with each other, and largest end face distance A of described first combination ring bank and described second combination ring bank is 6.8mm.The invention have the advantage that so that the better tightness of combination ring bank, service life is longer, and safety coefficient improves the most further by being respectively provided with boss structure and groove structure on the bank at the first combination ring bank and the second combination ring.
Description
Technical field
The present invention relates to machinery spare and accessory parts technical field, particularly relate to a kind of strong sealing staggered piston ring of automobile-used damping.
Background technology
In automobile absorber, the effect of piston ring is to make piston when motion, produces sealing thus obtain between piston and cylinder
Obtain hydraulic damping power.The open slot of traditional piston ring is longitudinal opening groove, is the machine in order to prevent piston from producing when motion
Heat energy produced by tool energy and damping energy-absorbing so that piston ring expanded by heating, thus cause piston ring and barrel locking, piston ring
Excessive wear.Although the setting of this longitudinal opening groove can solve the problem of piston ring thermal expansion well, but works as piston
When the movable shortage of heat produced is so that the opening part of piston ring is of completely closed, the damping force of design will be produced impact,
And the sealing property of this cannelure opening part is poor, easily causes oil liquid leakage, thus reduce hydraulic damping power.
Have studied a kind of staggered piston ring of automobile-used damping before my company, to some extent solve piston ring fluting
Position be easily caused oil liquid leakage, reduce the problem of hydraulic damping power, but due to the limited configurations designed before, at certain model
Enclose and interior can solve the problems referred to above.But through the operation of long period in real life, this structure there is also oil liquid leakage
Problem, simply comparing traditional mode effect can be better.
Summary of the invention
According to above-mentioned technical problem, it is an object of the invention to provide a kind of strong staggered piston ring of automobile-used damping that seals, logical
Crossing and arrange more preferable frame for movement and make the sealing of the staggered piston ring of automobile-used damping significantly submit to, the most long-term test is sent out
Existing, this structure can avoid the problem of oil liquid leakage completely, so that safety and life-span are obtained for further improvement.
Technical scheme is as follows:
A kind of strong seal the staggered piston ring of automobile-used damping, including the first combination ring bank and the second combination ring bank, described the
One combination ring bank is provided with boss structure, and described second combination ring bank is provided with groove structure, described boss structure and described groove knot
Structure has two planes that contact with each other, and largest end face distance A of described first combination ring bank and described second combination ring bank is
6.8mm。
Further, the boss height of described boss structure is 10mm.
Beneficial effects of the present invention:
The present invention is respectively provided with boss structure and groove structure on the bank by combining ring at the first combination ring bank and second, from
And making the better tightness of combination ring bank, service life is longer, and safety coefficient improves the most further.
Accompanying drawing explanation
Fig. 1 is the strong structural representation sealing the staggered piston ring of automobile-used damping of the present invention；
In figure: 1, the first combination ring bank, the 2, second combination ring bank, 3, boss structure, 4, groove structure, 5, contact plane,
A, largest end face distance.
Detailed description of the invention
As it is shown in figure 1, a kind of strong staggered piston ring of automobile-used damping that seals, combination ring bank includes the first combination ring bank 1 He
Second combination ring bank 2, it is characterised in that: described first combination ring bank 1 is provided with boss structure 3, and described second combination ring bank 2 is provided with
Groove structure 4.Boss structure 3 and groove structure 4 cooperate assembling, form a space sealed.Described boss structure 3 He
Described groove structure 4 has two planes 5 that contact with each other, and two contact planes 5 ensure that the strong sealing of entire combination ring bank, have
Dual sealing function.Described first combination ring bank 1 and described second combination ring bank 2 have a bigger end face distance A, maximum
End face distance A is 6.8mm.
As preferably, the boss height of described boss structure 3 is 10mm.Longer boss structure can make the sealing of entirety
Property be guaranteed, if but the oversize intensity that can affect again it, the most substantial amounts of it is demonstrated experimentally that when the height of boss structure is
Can ensure that during 10mm that its sealing property can guarantee that again the intensity of self.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of without departing from principle of the present invention, it is also possible to make some improvement or replacement, these improve or replace also
Should be regarded as protection scope of the present invention.
Claims (2)
1. the staggered piston ring of the automobile-used damping of strong sealing, including the first combination ring bank (1) and the second combination ring bank (2), its
Being characterised by: described first combination ring bank (1) is provided with boss structure (3), described second combination ring bank (2) is provided with groove structure
(4), described boss structure (3) and described groove structure (4) have two planes that contact with each other (5), described first combination ring bank (1)
