Description
Technical field
The utility model belongs to head gasket technical field, particularly relates to a kind of multi-layer metal cylinder gasket with rubber ring fixing novel structure being applicable to diesel engine.
Background technique
Head gasket is the important spare part of motor, is also multi-functional Sealing.Be positioned between cylinder block and head, both sealing load was about 0.3MPa, temperature reaches the cooling liquid of 110 DEG C, and pressure is 0.8MPa, temperature reaches the lubricant oil of 160 DEG C, and sealing load is more than the outburst combustion gas of 20MPa, temperature more than 1000 DEG C again.Seal the multi-functional characteristic that these three kinds of distinct fluids of character are head gasket " three envelopes "." three envelopes " quality of head gasket directly has influence on the working life of motor.The domestic motor newly developed almost adopts metal cylinder mat completely at present, and asbestos seal material that no longer adopt poor sealing performance, befouling environment, that forbidden in the world makes head gasket, and the non-asbestos material also not adopting rigidity lower makes head gasket.But for riding vehicle diesel engine, if design and fabrication technology is bad, there will be the Seepage such as combustion gas and cooling liquid and leak phenomenon.
Summary of the invention
The purpose of this utility model is that to propose a kind of sealability for the drawback of above-mentioned prior art excellent, long service life, environmentally friendly a kind of multi-layer metal cylinder gasket with rubber ring fixing novel structure.
The purpose of this utility model has been come by following technical solution.This multi-layer metal cylinder gasket with rubber ring fixing novel structure, mainly comprise pad, described pad is provided with combustion chamber hole, water hole, pressure oilhole, tappet hole, rubber ring, bolt hole and positioning hole, pad is made up of three-ply metal, comprise upper plate, middle plate and lower plate, three-piece metal plate, in lower plate, is fixed by the riveting bar riveting of this upper plate; Described upper plate forms the plane sealing band of sealing combustion gas at combustion chamber hole peripheral bead; The combustion chamber hole periphery of described middle plate is pressed with arc sealed muscle, and it and plane sealing band form to erect together puts overlapping double-deck gas sealing band; Described pressure oilhole and four the first water hole rubber rings seal, and the rubber ring skeleton of rubber ring is clipped by the jaw extruded by upper plate, lower plate by the rubber ring wherein on four the first water holes; Tappet hole and the water hole except four the first water holes adopt the sealing of inclination shape sealed muscle.
As preferably, the middle plate upper and lower surface of described pad scribbles rubber seal coating respectively, and the upper and lower surface of pad is all printed with rubber seal coating, and outer surface increases and is coated with antifriction release coating.
The beneficial effects of the utility model are: gas seal structure rationally, reliable performance, good sealing effect, long service life, be conducive to environmental protection, greatly improve reliability and the durability of motor.

Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in Figure 1, the utility model mainly comprises pad 1, and described pad 1 is provided with combustion chamber hole 2, water hole 3, pressure oilhole 4, tappet hole 5 (double do spill port), rubber ring 6, bolt hole 7 and positioning hole 8.As shown in Figure 2, pad 1 is made up of three-ply metal, comprises upper plate 11, middle plate 12 and lower plate 13.As shown in Figure 5, three-piece metal plate, in lower plate 13, is fixed by riveting bar 10 riveting of this upper plate 11.Described upper plate 11 forms the plane sealing band 15 of sealing combustion gas at combustion chamber hole 2 peripheral bead; Combustion chamber hole 2 periphery of described middle plate 12 is pressed with arc sealed muscle 14, and it and plane sealing band 15 form to erect together puts overlapping double-deck gas sealing band, with sealed high pressure combustion gas.Because it perpendicular puts superposition elastic sealing strip, with only having together compared with plane sealing band in the past, just there is stronger sealing function.
Described pressure oilhole 4 and four the first water hole 19 rubber rings 6 seal.As shown in Figure 3, because isolated edge is nearer, the rubber ring skeleton 16 of rubber ring 6 is clipped by the jaw 17 extruded by upper plate 11, lower plate 13 by the rubber ring 6 wherein on four the first water holes 19, and object is to skid off from edge for preventing, and can not move the effect of landing outward.Tappet hole 5 and the water hole 3 except four the first water holes 19 adopt inclination shape sealed muscle 18 to seal, as shown in Figure 6.
Middle plate 12 upper and lower surface of described pad 1 scribbles rubber seal coating respectively, and the upper and lower surface of pad 1 is all printed with rubber seal coating, fills up nao-and micro relief, and increases painting antifriction release coating at outer surface.
As shown in Figure 4, be provided with support block 9 at head gasket periphery, it be with upper plate 11 in its opening position flange is pressed on plate 12.
The utility model is not limited to above-mentioned mode of execution; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
