The purpose of this utility model is to overcome in the prior art compression ring deficiency easy to wear on the piston, and provide a kind of long service life, new structure, on piston the rational compression ring of configuration.
Fig. 1 is the structure diagram (along piston longitudinal sectional drawing) of automatic gap adjusting compression ring after installing on the piston on the internal combustion engine.
Fig. 2 is the ring direction of angulations allocation plan of each road (group) automatic gap adjusting compression ring when installing in piston channel.
Fig. 3 is the A-A sectional drawing of Fig. 2.
Component serial number in the diagram:
1, piston 2, oil ring 3, piston Xiao hole 4, associative ring first 5, associative ring second.
Be the twice oil ring on China X195 series internal combustion engine in the diagram, three road compression rings. Have plenty of one oil ring, two road compression rings on other internal combustion engine; Have plenty of one oil ring, three The road compression ring; Twice oil ring, three road compression rings are also arranged, in a word, be equipped with twice or three road single radial cut compression rings on the general piston. Piston is provided with the twice compression ring, and (not at grade) then is hexagonal angle or 180 ° of angle configurations between the twice compression ring opening; Be the hexagonal angle configuration between the three road compression ring openings (radial opening on the per pass compression ring) then when piston is provided with three road compression rings, this is the situation of prior art.
And the utility model is the automatic gap adjusting compression ring on the internal combustion engine, this automatic gap adjusting compression ring is called again: Combined gaseous ring, just the per pass compression ring (establishing compression ring one in prior art one annular groove) in the piston ring groove is a kind of Combined gaseous ring, this Combined gaseous ring is by associative ring first 4, associative ring second 5 constitutes, ring first 4, cooperate for smooth bevel between the ring second 5, ring first 4, the cross section of ring second 5 is trapezoidal, the internal diameter of its ring, the external diameter physical dimension equates respectively, ring first 4, be provided with a radial opening respectively on the ring second 5, ring first 4, the radial opening 180 ° of angle balanced configurations of staggering of ring second 5 are one group of Combined gaseous ring, and one group of Combined gaseous ring just is installed in each the road compression on the piston.If piston is provided with the twice compression, then between every group of Combined gaseous ring opening along piston shaft to being 90 ° of angles configurations; If piston is provided with three road compressions, then between every group of Combined gaseous ring opening along piston shaft to being that 60 ° of angles are configured in respectively in the annular groove of three road compressions on the piston.
During internal combustion engine, piston is together with ring (oil ring, compression ring) reciprocating stroke in cylinder sleeve (along the piston axially reciprocating) on the piston, work after a stage, because the circumscribed tension force effect of piston ring, the piston collar extension progressively strengthens, and just the inside circle radius in the footpath of piston ring becomes big, exradius diminishes, the thickness (width) of ring diminishes, and the top and bottom of ring back and forth contact with piston ring groove, because the end wear of ring broadens piston ring groove; Simultaneously because the friction between ring and the cylinder sleeve makes cylinder sleeve bore become big.That is to say, when internal combustion engine after a period of time, because between the upper and lower end face of cylinder sleeve, piston (annular groove) and piston ring (the main compression ring that refers to) and the gap between piston ring and the cylinder sleeve increases, form axially gas leakage, poorly sealed, burn oil, compression ratio descends, combustion engine powered property, Economy variation.Especially after the compression ring gauge wear, the opening of ring itself strengthens (opened gap increasing), under single groove in the annular groove, the single radial cut ring situation, easilier cause axial gas leakage, the Combined gaseous ring that the utility model is provided with, be the automatic gap adjusting compression ring, just can just can change the cycle of compression ring along length along the working life of long compression ring.
After installing Combined gaseous ring in the annular groove, when internal combustion engine after a period of time, annular groove, associative ring,, and cylinder sleeve bore all can wear and tear, at this moment, and can be between associative ring first 4, the associative ring second 5 along its trapezoidal smooth contact surface, form radially, axial micro-slippage, make the gap smaller between annular groove, ring, the cylinder sleeve, just this associative ring has played the automatic gap adjusting effect, so be called " automatic gap adjusting compression ring ".The opening of this associative ring (ring first, the ring second) several angle that staggers makes ring (first) opening kept off by another ring (second) opening, can not form direct gas leakage.
After the utility model is succeeded in developing, use through inside, test, when piston, the cover material of cylinder and physical dimension homogeneous phase with situation under, the material of single track ring and associative ring and interior external diameter, thickness (width) homogeneous phase are with under the situation, when internal combustion engine after identical a period of time, internal-combustion engine gas leakage, burn oil, the outlet pipe over-emitting black exhaust of single track trip ring are installed, and power character, Economy descend, and the internal-combustion engine that associative ring is installed then works on normally.When the wearing and tearing of internal-combustion engine compression ring, the gas leakage of single track trip ring, cold machine hard-to-start especially are installed, and use the internal-combustion engine of the installation associative ring of identical time, cold machine then starts normally (easily starting).
By Fig. 1, find out among Fig. 3, associative ring first 4 in the automatic gap adjusting compression ring, associative ring second 5 is at radial direction will contact with cylinder sleeve bore (movingly), ring first 4 and cylinder sleeve bore surface of contact little (upper base of trapezoid), ring second 5 and cylinder sleeve bore area of contact big (fall trapezoidal upper base), 4 pairs of cylinder sleeve bore pressure of ring first are big, 5 pairs of cylinder sleeve bore pressure of ring second are little, in the internal combustion engine process, it is poor to form wearing and tearing (amount), the outer rim wear extent of promptly encircling first 4 surpasses the outer rim wear extent of ring second 5, just behind one section of the internal combustion engine, ring first 4, ring second 5 is because the cylindrical wear extent is different, and cause encircling first 4, the radius structure size of ring second 5 is variant, ring first 4, encircle between the second 5 along smooth bevel slip (staggering), just the ring first 4 of Combined gaseous ring, ring second 5 adjusted automatically and piston ring groove between gap (axially), and the gap between the cylinder sleeve (radially).Conventional piston compression ring in this automatic gap adjusting compression ring (Combined gaseous ring) and the prior art, the installation in piston ring is general.
