Abstract
The utility model discloses a cylinder gasket structure which comprises a gasket body structure formed by three layers of substrates, wherein the intermediate layer is an aluminizing plate, the upper layer and the lower layer are both stainless iron layers, cylinder holes arranged at intervals are distributed in a gasket body, mounting holes, water holes, screwed holes and tappet holes are distributed in the positions, on the outer sides of the cylinder holes, of the gasket body, each tappet hole is in one side of the corresponding cylinder hole, trapezoid location holes are formed in one end of the gasket body, and rubber seal convex ribs are arranged at the outer edge positions of the cylinder holes, the outer edge positions of the screwed holes, the outer edge positions of the tappet holes and the outer edge positions of the trapezoid location holes respectively. The cylinder gasket structure is good in performance, long in service life and recyclable after being disassembled and assembled and facilitates environment protection; because of the structure that the rubber seal convex ribs are arranged at the outer edge positions of the cylinder holes, the outer edge positions of the screwed holes, the outer edge positions of the tappet holes and the outer edge positions of the trapezoid location holes, the sealing performance of the cylinder gasket structure is good, the requirements of internal combustion engines for thermal loads and mechanical loads are met, and the cylinder gasket structure is good in stability in the use process through the structure of a longitudinal locating groove and the trapezoid location holes in the end portions.
Description
Technical field
The utility model relates to cylinder seal technical field, relates in particular to a kind of head gasket structure.
Background technique
The effect of head gasket is the microscopic void of filling up between cylinder block and head, guarantee that there is good sealing at junction plane place, and then the sealing that guarantees firing chamber prevents that cylinder leakage tester and water jacket from leaking, along with continually strengthening of internal-combustion engine, heat load and mechanical load all constantly increase, the sealing of head gasket is more and more important, more and more higher to the requirement of structure and material, thereby traditional head gasket is also more and more not suitable for present use.
Model utility content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of head gasket structure is provided.
The utility model is achieved through the following technical solutions:
A kind of head gasket structure, it is characterized in that: the shim body structure that includes three layers of substrate composition, its mesosphere is alclad sheet, the upper and lower two-layer stainless iron layer that is, in described shim body, be distributed with spaced cylinder-bore, in the shim body in described cylinder-bore outside, be distributed with the tappet bore of mounting hole, water hole, screw hole and one side, one end of described shim body is provided with trapezoidal positioning hole, and the outward edge position of described cylinder-bore, tapped hole, tappet bore and trapezoidal positioning hole is respectively equipped with rubber seal convex tendon.
The outer side that is positioned at tappet bore one side in described shim body is provided with longitudinal register groove.
The utility model has the advantages that:
The utility model is by three layers of shim body structure of two-layer stainless iron layer and one deck alclad sheet composition, its Performance Ratio is better, long service life, recoverable after dismounting simultaneously, be beneficial to environmental protection, the structure of the rubber seal convex tendon of the outward edge position by shim body upper cylinder hole, tapped hole, tappet bore and trapezoidal positioning hole, its good seal performance, met the requirement of internal-combustion engine to heat load and mechanical load, and by the structure of the trapezoidal positioning hole of longitudinal register groove and end, make in its using process good stability.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to accompanying drawing, a kind of head gasket structure, include shim body 1 structure of three layers of substrate composition, its mesosphere is alclad sheet, the upper and lower two-layer stainless iron layer that is, in shim body 1, be distributed with spaced cylinder-bore 2, in the shim body in cylinder-bore 2 outsides, be distributed with the tappet bore 6 of mounting hole 3, water hole 4, screw hole 5 and one side, one end of shim body 1 is provided with trapezoidal positioning hole 7, and the outward edge position of cylinder-bore 2, tapped hole 5, tappet bore 6 and trapezoidal positioning hole 7 is respectively equipped with rubber seal convex tendon 8.The outer side that is positioned at tappet bore 6 one sides in shim body 1 is provided with longitudinal register groove 9.
Claims (2)
