Summary of the invention
The wave concave-convex type internal-combustion engine cylinder gasket that the object of the present invention is to provide a kind of good sealing effect, long service life, cost of production lower.
Technological scheme of the present invention is: wave concave-convex type internal-combustion engine cylinder gasket, comprise substrate, substrate is provided with cylinder mouth macropore and multiple through hole (in order to express easily, herein by Tappet Hole, cooling water hole, oil-through hole, fastening bolt holes is referred to as " through hole "), feature is, substrate is provided with waveform annular shim around peripheral part of cylinder mouth, waveform annular shim forms waveform male and fomale(M&F), this waveform male and fomale(M&F) is made up of the undulatory closed ring in some roads, the crest of each road corrugated closed ring keeps flushing, waveform annular shim is fixedly connected on the substrate of cylinder mouth peripheral part.
In order to realize goal of the invention better, the waveform male and fomale(M&F) described in the technical program is at least made up of the undulatory closed ring of twice.The number of channels of the corrugated closed ring of waveform male and fomale(M&F) is more, and technique effect is better, but the more manufactures of number of channels are taken a lot of work, takes material and be also inevitable.
Waveform annular shim of the present invention adopts certain thickness sheet metal to make, the waveform male and fomale(M&F) be made up of it can have two kinds of structural types: one be the substrate around cylinder mouth peripheral part corresponding with waveform annular shim is plane, and waveform annular shim and plane substrate connect and compose waveform male and fomale(M&F); Two be the substrate around cylinder mouth peripheral part corresponding with waveform annular shim also for waveform is concavo-convex, waveform annular shim and the concavo-convex substrate of waveform connect and compose waveform male and fomale(M&F).In above-mentioned two kinds of structural types, waveform annular shim both can be arranged on a surface of substrate, also can be arranged on two surfaces up and down of substrate simultaneously.
The surrounding edge of cylinder of internal-combustion engine sealing gasket cylinder mouth macropore is made ripple glaze concaveconvex shape by the present invention, not only there is well withstand voltage, heat resistance, and owing to having certain elasticity, when wave concave-convex type cylinder of internal-combustion engine sealing gasket can discharge certain spring-back force after standing clamping bolt extruding, the hard contact between cylinder block, head gasket, cylinder head three can be alleviated, alleviate impact force, improve sealability, increase the service life.Secondly, the waveform annular shim made owing to adopting sheet metal fixes (as welding etc.) on substrate so that bed course form is additional in addition, so not only can make in processing technology simple, and substrate and sheet metal can be more flexible in material selection, greatly can reduce cost of production.
Below in conjunction with drawings and Examples, the present invention is described in detail.
