Embodiment
This embodiment provides a kind of cylinder end seal pad, and it has good sealing effect.This embodiment also provides a kind of motor that comprises a said cylinder sealing gasket.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of cylinder end seal pad that this embodiment provides, be provided with cutout hole 11 and oilhole 10 and a plurality of water hole 16, sealing gasket is provided with and is arranged on the periphery of cutout hole 11 and to extraradial the first corrugated projection, by a plurality of water holes 16, surrounds and to extraradial the second corrugated projection and oilhole 10 is surrounded and to extraradial the 3rd corrugated projection, and the height of the first corrugated projection is greater than the height of the second corrugated projection and the 3rd corrugated projection.
This embodiment, by the cutout hole of sealing gasket 11 being provided with centered by cutout hole 11 and to extraradial the first corrugated projection, can form linear sealing band between the first corrugated projection and cylinder head around, and sealing effect is better.
In addition, due in engine working process, the pressure of the combustion mixture in cutout hole is greater than 7MPa, hydraulic pressure pressure in oilhole in oil pressure and water hole is less than 0.9MPa, at sealing gasket, be connected power with cylinder head fixedly in the situation that, the sealing gasket that this embodiment provides can, by regulating the height of the first corrugated projection, the second corrugated projection and the 3rd corrugated projection, be adjusted the distribution of connection power, to guarantee the sealing of sealing gasket and each position of cylinder head.In this embodiment near the height of the first corrugated projection of cutout hole 11 height higher than other corrugated projection, after sealing gasket is connected with cylinder head, such as, the two can be connected by bolt, certainly, also can be connected by alternate manner, such as pin joint, riveted joint etc.Connection power between the two, the axial force of bolt is distributed near the component of cutout hole 11 positions greatlyr, has effectively guaranteed the sealing of cutout hole 11 positions, and can guarantee the sealing of oilhole and position, water hole simultaneously.
In the preferred version of this embodiment, near the first corrugated convexity the second corrugated projection and high 0.05-0.1mm of the 3rd corrugated projection of cutout hole 11.
It should be noted that, this embodiment is by arranging the height of corrugated projection, can the distribution of adjusting bolt axial force on sealing gasket, the high 0.05-0.1mm of other corrugated projection of the first corrugated convexity of close cutout hole 11 in this embodiment, so arrange, the distribution of the axial force of bolt on sealing gasket is comparatively reasonable, has better sealing effect.
It should be noted that, the sealing gasket that this embodiment provides can comprise the three stacked pads of putting, and the opposite position of three layers of pad is provided with 12, three layers of pad of riveted holes and is connected by being plugged in the rivet of riveted holes 12.Wherein, middle pad material can be steel plate, and the pad material of both sides can be for applying the corrosion resistant plate of fluorine rubber.Certainly, middle pad and the pad of both sides also can be other material, such as, middle pad material can also be copper coin, zine plate etc., the pad material of both sides can also be silica gel, nylon etc.
When preventing three layers of pad to be riveted together, riveted joint tension can cause having certain dislocation between three layers of pad, between three layers of pad itself in conjunction with out-of-flatness, there is the problem of arch camber.In the preferred version of this embodiment, the aperture of riveted holes 12 is greater than the diameter of rivet.So arrange, between rivet and riveted holes 12, have certain gap, can prevent the problem of pad arch camber.
As preferably and for example, after cylinder end seal pad is riveted, there is the gap of 0.1-0.2mm in the head of rivet and sealing gasket, and the distance between the axial and sealing gasket of rivet is 0.1-0.2mm; There is the gap of 0.1-0.2mm in the outer circumferential face of rivet and riveted holes 12, rivet is radially 0.1-0.2mm with the distance of rivet hole.So arrange, can, when assurance is riveted together three layers of pad reliably, can effectively prevent the problem of pad generation arch camber.
This embodiment also provides a kind of motor, comprises cylinder end seal pad as above.So arrange, the motor that this embodiment provides, between its cylinder head and cylinder cap, can pad existing sealing reliably by cylinder end seal, the derivation of the beneficial effect that the derivation of this beneficial effect and said cylinder sealing gasket brings is substantially similar, therefore repeat no more herein.
In addition, it should be noted that, in this embodiment, cylinder end seal pad and cylinder head opposite position can be provided with positioning pin hole 13, and cylinder end seal pad can be connected in cylinder head by being plugged in the pin of positioning pin hole 13.So, the mode that can connect by pin, is connected in cylinder end seal pad on cylinder head.
In addition, positioning pin hole 13 tolerances of cylinder end seal pad of the prior art are less than normal, because cylinder head positioning pin hole 13 exists certain positioning tolerance, so cylinder end seal pad cannot entirely be assembled on the positioning pin hole 13 on cylinder head, in a lot of situations, can only subdue by cylinder head.And that this assembling mode probably causes cylinder end seal pad to engage with cylinder face is 100% smooth, probably exist certain wrinkling.
In order to address this problem, in this embodiment, the tolerance of positioning pin hole 13 can be set to 0.2-0.3mm.
So arrange, when cylinder end seal pad is assembled on cylinder head, cylinder end seal pad can more entirely be assembled on cylinder head, has avoided because cylinder end seal paves wrinkle, and has caused the poor problem of sealing.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To these embodiments' multiple modification, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
