Description

Metal oil pan gasket of high reliability

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of the car gasket, concretely relates to metal oil pan gasket of high reliability.

[ background of the invention ]

At present, a sealing gasket between an engine cylinder body and an oil pan is generally made of a soft gasket made of asbestos-free materials, and for the oil pan needing to be sealed in a whole circle, the adopted gasket structure is also integral, namely, one gasket is made of only one material. The production processing is obtained by adopting an integral cutting or stamping method. For the engine, the bigger the engine size is, the bigger the oil pan size is, the oil pan sealing plane can be increased, the integral sealing gasket formed by one-time blanking is adopted, the gasket is required to be made to be larger, the middle part of the gasket belongs to an unnecessary part and can only be used for raw materials of other small gaskets, the cost of raw materials, processing, management and the like of a manufacturer is improved, related manufacturers design the oil pan gasket according to the pure hard gasket, but because the planeness of each processing surface and the microscopic unevenness such as local knife lines exist objectively, the pure hard gasket cannot provide sealing compensation, and the reliable sealing function is difficult to realize.

The prior technical scheme is as follows: the asbestos-free soft gasket between the oil pan and the engine cylinder body has a material compression ratio of about 15-25%, and realizes sealing by material extrusion filling. The soft gasket without asbestos material has compression after assembly, and when the oil pan with cast iron application is assembled with a bracket of a whole automobile factory, the gasket can generate certain offset, which is not beneficial to reliable assembly. In the actual use process of the whole vehicle with more jolting and vibration working conditions, the problems of gasket crushing, aging and the like easily occur, so that the problems of loosening of the moment of the oil pan bolt, sealing failure, oil leakage and the like are caused. While a hard shim alone is beneficial for torque stabilization, a reliable seal cannot be achieved. The proposal of the scheme is to provide a metal oil pan gasket scheme with high reliability and low cost. The framework is spliced by riveting a steel plate, and then the whole ring of rubber is pressed and installed to realize reliable sealing.

The above background disclosure is only provided to aid understanding of the inventive concepts and solutions of the present invention, and it does not necessarily pertain to the prior art of this patent application, and it should not be used to assess the novelty and inventive aspects of this application without explicit evidence that such contents are disclosed at the filing date of this patent application.

[ detailed description ] embodiments

The following is a detailed description of specific embodiments.

The present invention will be described in further detail with reference to the following embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.

As shown in fig. 1, a metal oil pan gasket with high reliability comprises a gasket body, wherein the gasket body is a rectangular hollowed-out gasket body formed by two long split gaskets 1 and two short split gaskets 2, the two long split gaskets 1 and the two short split gaskets 2 are connected in a riveting manner to form the gasket body, a plurality of fixing through holes are formed in the top surfaces of the two long split gaskets 1, and the gasket body is made of stainless steel or alloy material.

As shown in fig. 2-4, the inner side of the gasket body is provided with a joining strip 4, the top surface of the joining strip 4 is provided with a plurality of semicircular grooves, the joining strip 4 is provided with a sealing gasket 3, four corners of the inner side of the sealing gasket 3 are provided with compensation areas 3-1, the top of each of the two short split gaskets 2 is provided with a plurality of counter bores, the bottom of each counter bore is provided with a through hole smaller than the diameter of the counter bore, the inner side surfaces of the two short split gaskets 2 are provided with openings, the openings are connected with the side surfaces of the counter bores, the sealing gasket 3 is formed by parallelly surrounding a plurality of convex ribs, the middle of the outer side surface of the sealing gasket 3 is provided with a circle of notch, the sealing gasket 3 is sleeved on the joining strip 4 through the notch, and the end surfaces of. The short side face of the sealing washer 3 is provided with an ear corresponding to the counter bore of the short split gasket 2, the middle part of the ear of the sealing washer 3 is provided with a round hole corresponding to the through hole at the bottom of the counter bore of the short split gasket 2, and the ear at the short side of the sealing washer 3 is arranged in the counter bore of the short split gasket 2. The sealing washer is made of rubber.

As shown in fig. 5, the compensation area 3-1 is a matrix square block formed by a plurality of vertical sealing transverse ribs and vertical sealing ribs.

In addition, the thickness of the sealing gasket is greater than the thickness of the gasket body.

The working principle is as follows: after assembling this oil pan gasket, as shown in fig. 2 and fig. 3, before not tightening the oil pan, seal ring 3's thickness is greater than the thickness of gasket body, during the installation oil pan, this oil pan gasket wholly receives the oil pan extrusion of top part and bottom, seal ring 3's partial material extrudees the semicircular groove who links up strip 4, form limiting displacement, the displacement condition can not appear in seal ring 3, guarantee the leakproofness, seal ring 3's compensation district is in the installation, do further sealing to four angles of gasket body riveting, can not the oil leak when the gap appears in the four riveted angle micro-movements of assurance installation.

The utility model discloses through set up the semicircular groove on linking up the strip, and set up the seal ring on linking up the strip, when the seal ring produced the deformation in the installation, part of the seal ring can block into the recess, prevented that the gasket from producing the displacement; at the integral seal ring of gasket inner circle pressure equipment, realize that the microcosmic clearance that pure hard material can't realize remedies to be provided with rubber packing compensation area in the riveting department inboard of gasket body, can not appear the gap because of the fine motion appears in the riveting department in guaranteeing the installation, and can effectual reduction seal ring during the installation pile up of four angles air, unnecessary air runs out and the not hard up phenomenon of seal ring appears when avoiding the oil pan to rock, realizes reliably sealing.
