Abstract
The utility model provides a kind of engine main bearing cover, the relative main bearing bore center, installation seam face of this engine main bearing cover is asymmetric, and namely two symmetrical line installing seam face of engine main bearing cover are arranged to not overlap relative to the centre symmetry line of main bearing hole.In installation process, if engine main bearing cover installs seams in the face of flirting under condition at two, the bent axle in engine main bearing cover and main bearing hole is interfered, and can not be installed on engine cylinder-body.Thus ensure that the accuracy of installation.
Description
Technical field
The utility model relates to a kind of engine component, is specially engine main bearing cover.
Background technique
Current passenger car market requires increasingly harsh to engine performance, as the basic part of motor---the Design and manufacture of cylinder block also does more careful and more careful thereupon, requirement is also more and more stricter.And engine main bearing cover is used for fixed crankshaft, play the effect of the load that withstands shocks.Therefore engine main bearing cover is as carrying stress members important in cylinder body, and its installation directly has influence on function of the engine.
Existing engine main bearing cover generally all adopts two to install seam face relative main bearing bore centrosymmetric structure.But this structure makes engine main bearing cover install seam in the face of also installing on engine cylinder-body when adjusting at two.Be very easy to like this cause mistake to install, thus cause engine breakdown.
Model utility content
According to the utility model, provide a kind of engine main bearing cover, two symmetrical line installing seam face of engine main bearing cover are arranged to not overlap relative to the centre symmetry line of main bearing hole.
Two symmetrical line installing seam face of engine main bearing cover depart from 0.25 to 1mm relative to the centre symmetry line of main bearing hole.
In installation process, if engine main bearing cover relative to two, correct mounting point seam in the face of flirting under condition, the bent axle in engine main bearing cover and main bearing hole is interfered, and can not be installed on engine cylinder-body.When mounting point is correct, engine main bearing cover could can only be installed on engine cylinder-body.Therefore avoid engine main bearing cover mistake to install.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.In the drawings:
Fig. 1 shows according to engine main bearing cover of the present utility model.
In the accompanying drawings, not according to the scale of reality.
Embodiment
To introduce below according to a preferred embodiment of the present utility model.
Fig. 1 show schematically show engine main bearing cover 10.As shown in the figure, engine main bearing cover 10 comprises main bearing cap main body 4.This main bearing cap main body 4 comprises main bearing hole 3, main bearing cap construction bolt hole 5 and 6, and installs seam face 1 and 2.These structures are known by those skilled in the art, are described in this and omit therefore in detail.
As shown in Figure 1, the installation seam face 1 of the first end of main bearing cap main body 4 and the installation seam face 2 of the second end are in the both sides of main bearing cap main body 4 respectively, and the distance between them is L.In addition, the distance that the first end of main bearing cap main body 4 is installed between seam face 1 and main bearing hole 3 center is l.
According to the utility model, the installation seam face 1 of the first end of main bearing cap main body 4 and the installation seam face 2 of the second end are arranged to asymmetrical for the center of main bearing hole 3.That is, the centre symmetry line between the installation seam face 1 of the first end of main bearing cap main body 4 and the installation seam face 2 of the second end is arranged to not overlap relative to the centre symmetry line of main bearing hole 3.Those skilled in the art will readily understand, in this case, installation seam face 1 and the distance l at main bearing hole 3 center of first end are not equal to the half of the distance L in the installation seam face 1 of first end and the installation seam face 2 of the second end.
Like this, suppose that the installation seam face 1 of first end and the installation seam face 2 of the second end there occurs the situation of exchanging in installation process, then main bearing cap main body 4 can produce with bent axle and interfere, and causes can not being installed on engine cylinder-body.Therefore, by design of the present utility model, the installation of mistake can be avoided, ensure that the accuracy of installation.
According to a preferred embodiment, two symmetrical line installing seam face of main bearing cap main body 4 depart from 0.25 to 1mm relative to the centre symmetry line of main bearing hole 3.
The foregoing is only preferred implementation of the present utility model; but the utility model protection domain is not limited thereto; any those skilled in the art is in technical scope disclosed in the utility model; can easily carry out changing or changing, and this change or change all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
Claims (2)
1. an engine main bearing cover, is characterized in that, two symmetrical line installing seam face of described engine main bearing cover are arranged to not overlap relative to the centre symmetry line of main bearing hole.
2. engine main bearing cover according to claim 1, is characterized in that, two symmetrical line installing seam face of described engine main bearing cover depart from 0.25 to 1mm relative to the centre symmetry line of main bearing hole.
