Abstract
The present invention relates to mechanical spare and accessory parts technical fields, more particularly to one kind to seal the staggered piston ring of automobile-used damping by force.The technical solution adopted by the present invention is that: one kind sealing by force the staggered piston ring of automobile-used damping, including first group of cyclization bank and second group of cyclization bank, first group of cyclization bank is equipped with boss structure, second group of cyclization bank is equipped with groove structure, there are two the plane that contacts with each other, the largest end face distance A of first group of cyclization bank and second group of cyclization bank is 6.8mm for the boss structure and the groove structure.The invention has the advantages that, to make a group better tightness for cyclization bank, the service life is longer, and safety coefficient also further increases by the way that boss structure and groove structure are respectively set on the bank in first group of cyclization bank and second group of cyclization.
Description
Technical field
The present invention relates to mechanical spare and accessory parts technical fields, more particularly to one kind to seal the staggered piston ring of automobile-used damping by force.
Background technique
The effect of piston ring is to make piston during exercise in automobile absorber, and sealing is generated between piston and cylinder to obtain
Obtain hydraulic damping power.The open slot of traditional piston ring is longitudinal opening slot, is the machine that piston generates during exercise in order to prevent
Thermal energy caused by tool energy and damping energy-absorbing, so that piston ring expanded by heating, so as to cause piston ring and barrel locking, piston ring
Excessive wear.Although the setting of this longitudinal opening slot can well solve the problem of piston ring thermal expansion, work as piston
The shortage of heat that activity generates will have an impact the damping force of design so that when the opening of piston ring is closed completely,
And the sealing performance of the longitudinal slot opening is poor, is easy to cause oil liquid leakage, to reduce hydraulic damping power.
A kind of staggered piston ring of automobile-used damping is had studied before my company, solves piston ring fluting to a certain extent
Position be easy to cause oil liquid leakage, reduce the problem of hydraulic damping power, but limited configurations due to designing before, in certain model
It can solve the above problem in enclosing.But pass through the operation of long period in real life, there is also oil liquid leakages for this structure
Problem, only can be better compared to traditional mode effect.
Summary of the invention
According to above-mentioned technical problem, the object of the present invention is to provide one kind to seal the staggered piston ring of automobile-used damping by force, leads to
It crosses and better mechanical structure is set submits the leakproofness of the staggered piston ring of automobile-used damping significantly, often long-term test hair
Existing, this structure can avoid the problem that oil liquid leakage completely, so that safety and service life be made all to have obtained further improvement.
Technical scheme is as follows:
One kind seals by force the staggered piston ring of automobile-used damping, including first group of cyclization bank and second group of cyclization bank, and described first group
Cyclization bank is equipped with boss structure, and second group of cyclization bank is equipped with groove structure, and the boss structure and the groove structure have
The largest end face distance A of two planes that contact with each other, first group of cyclization bank and second group of cyclization bank is 6.8mm.
Further, the boss height of the boss structure is 10mm.
Beneficial effects of the present invention:
The present invention by the way that boss structure and groove structure are respectively set on the bank in first group of cyclization bank and second group of cyclization, thus
Make a group better tightness for cyclization bank, the service life is longer, and safety coefficient also further increases.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for sealing the staggered piston ring of automobile-used damping by force of the invention；
In figure: 1, first group of cyclization bank, 2, second groups of cyclization banks, 3, boss structure, 4, groove structure, 5, contact plane, A, most
Large end face distance.
Specific embodiment
As shown in Figure 1, a kind of seal by force the staggered piston ring of automobile-used damping, group cyclization bank includes first group of 1 He of cyclization bank
Second group of cyclization bank 2, it is characterised in that: first group of cyclization bank 1 is equipped with boss structure 3, and second group of cyclization bank 2 is equipped with
Groove structure 4.Boss structure 3 and groove structure 4, which cooperate, to be assembled, and the space of a sealing is formed.3 He of boss structure
There are two the plane 5 that contacts with each other, two contact planes 5 ensure that the strong leakproofness of entire combination ring bank, have the groove structure 4
Dual sealing function.First group of cyclization bank 1 and second group of cyclization bank 2 have a biggish end face distance A, maximum
End face distance A is 6.8mm.
Preferably, the boss height of the boss structure 3 is 10mm.Longer boss structure can make whole sealing
Property be guaranteed, it is often a large amount of it is demonstrated experimentally that the height when boss structure is but if too long and will affect its intensity
It can ensure that its sealing performance can guarantee the intensity of itself again when 10mm.
The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art
For, without departing from the principles of the present invention, it can also make several improvements or replace, these are improved or replacement
It should be regarded as protection scope of the present invention.
