Description
Technical field
The invention belongs to automobile technical field, relate to auto parts and components structure, particularly relate to a kind of sealing configuration of timing chain cover place.
Background technique
Timing chain cover is generally positioned at motor head, upper end is connected with cylinder body, lower end is connected with oil sump, this part Main Function is by gluing in the plane of timing chain cover, common timing chain cover sealing gluing place structure is closed plane, as shown in Figure 1, timing chain cover 10, colloidal sol 20 and cylinder body 30 three are connected to form colloidal sol sealing configuration to seal and fixed crankshaft Front oil seal, water pump etc. motor head face, thus realize motor can not produce oil leakage phenomenon in operation process, ensure the reliable running of motor.Although this structure plays certain seal action, but in the process of automobile running, due to road conditions or other factors cause vehicle body occur vibrations or collision time, this structure well can not resist impact shock distortion, and the sol layer side realizing seal action is easily cut off by the sharp edge of adjacent structure, thus weaken the sealability of sol layer, affect Engine Oil Cleanliness.
Summary of the invention
The object of the present invention is to provide a kind of colloidal sol sealing configuration, while the sealing function effectively realizing sol layer, the performance of the opposing impact shock of sol layer improves.
For achieving the above object, solution of the present invention is:

Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
As shown in Figure 2, a kind of colloidal sol sealing configuration, comprise be positioned at lower floor timing chain cover 1, be positioned at middle sol layer 2 and be positioned at the cylinder body 3 on upper strata, sol layer 2 covers the surface of timing chain cover 1 to connect and sealed cylinder block 3 and timing chain cover 1, and colloidal sol sealing configuration is provided with colloidal sol groove structure.The side that colloidal sol groove structural entity is parallel to timing chain cover 1 or cylinder body 3 moves towards to arrange, and the cross section of colloidal sol groove structure is right-angled triangle, and the side of timing chain cover 1 or cylinder body 3 is a right angle side of colloidal sol groove structure.Sol layer 2 fills above-mentioned colloidal sol groove structure,
Colloidal sol groove structure both for being arranged on a colloidal sol groove 4 of the side of timing chain cover 1 or cylinder body 3, can also can be side two the colloidal sol grooves 4 being arranged on timing chain cover 1 or cylinder body 3.When colloidal sol groove structure is provided with two colloidal sol grooves 4, colloidal sol groove 4 lays respectively at the not homonymy of timing chain cover 1 or cylinder body 3, whole colloidal sol groove 4 filled by the colloidal sol of sol layer 2, when timing chain cover 1 or cylinder body 3 are provided with colloidal sol groove 4, the side that colloidal sol groove 4 entirety is parallel to timing chain cover 1 or cylinder body 3 moves towards to arrange, and the flute length of colloidal sol groove is equal with the length of the left and right side of timing chain cover 1.The cross section of colloidal sol groove 4 is right-angled triangle, and the side of timing chain cover 1 or cylinder body 3 is a right angle side of colloidal sol groove 4.
As shown in Figure 3, in the assembly process of colloidal sol sealing configuration, be generally first install timing chain cover 1, then smear a certain amount of colloidal sol on timing chain cover 1 top layer, the timing chain cover 1 finally scribbling colloidal sol is arranged on cylinder body 3.Fig. 4 is timing chain cover 1, actual annexation figure when sol layer 2 and cylinder body 3 assemble, the present invention offers one or two colloidal sol grooves 4 at cylinder body 3 and the left and right sides place of timing chain cover 1 junction plane, when cylinder body 3 extrudes colloidal sol, colloidal sol can fill up timing chain cover 1 with the gap of cylinder body 3 junction plane, to be extruded with the colloidal sol of timing chain cover 1 junction plane side at cylinder body 3 flows in colloidal sol groove 4 simultaneously, thus while cylinder body 3 and timing chain cover 1 junction plane entirety are sealed, both gaps of junction plane side are also sealed, unnecessary colloidal sol and the silica gel of extruding sealing surface after making assembling remain on junction, play secondary seal effect.
In addition, arrange colloidal sol groove 4 at cylinder body 3 and the junction of timing chain cover 1 sidewall, colloidal sol fully can solidify in colloidal sol groove 4, thus forms adequate thickness size sol layer 2 in the junction of sidewall.Because colloidal sol inherently has certain fracture elongation, at the thickness that the sol layer 2 of the junction of sidewall is specifically enough again, for original colloidal sol sealing configuration, the sealing configuration being provided with colloidal sol groove 4 improves the ability of the opposing impact shock distortion at sol layer 2 two ends.
Simultaneously, because cylinder body 3 and the colloidal sol of the junction of timing chain cover 1 sidewall have enough thickness, therefore in the assembly process of whole colloidal sol sealing configuration, when cylinder body 3 is installed on timing chain cover 1, sharp keen junction plane limit effectively can be avoided to cut off sealing joint strip, cause colloidal sol also thoroughly unfixing in sol layer 2 to flow out from incision.
And the phenomenons such as the right angle side that in original sealing configuration, the junction of sidewall exists or burr, adhesive tape is easily cut off, and thus causes when driving, due to the possibility shaking and cause sol layer 2 to come off from incision of jolting.The sealing configuration being provided with colloidal sol groove 4 with chamfering, comparatively speaking, can reduce the possibility that junction adhesive tape is cut-off in the junction of cylinder body 3 and timing chain cover 1 sidewall.
Owing to needing a certain amount of colloidal sol to fill in colloidal sol groove 4, consider the user cost of colloidal sol and the equilibrium problem of sealing effect, in diagram illustrated embodiment, in colloidal sol sealing configuration, be provided with a colloidal sol groove 4.As previously mentioned, due to assembling timing chain cover 1, then cylinder body 3 is being covered on timing chain cover 1, therefore in order to better reach sealing effect, colloidal sol groove 4 is located on timing chain cover 1.
As calculated, be in the colloidal sol groove 4 of right-angled triangle at cross section, when the angular range of acute angle theta corresponding to the side of timing chain cover 1 or cylinder body 3 is 35 degree to 55 degree, when two right angle side length ranges of right-angled triangle are 2 to 3mm, effectively can meet the demand of junction plane side edge to sol layer 2 thickness, also can form good secondary seal effect.
In the present embodiment, the colloidal sol groove of colloidal sol groove 4 to be cross sections be isosceles right triangle, and the right angle side length of isosceles right triangle is 2mm.
Above-mentioned is can understand and apply the invention for ease of those skilled in the art to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to embodiment here, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
