The connecting portion of semi-circular structure, described connecting portion is connected the circle being formed for bearing placement with the cylinder body being correspondingly provided with semi-circular structure
Hole.
As the improvement of technique scheme, the connecting portion of described semi-circular structure has two and connects end, described connection end
Centered on the axis of described circular port, line is symmetrical set, and described connection end is provided with the first peace connecting for described cylinder body
Dress hole.
It as the improvement of technique scheme, is positioned at the first installing hole and the position of the side of the described bearing cap unit of head end
Being dowel hole in the first installing hole of the opposite side of the described bearing cap unit of tail end, described cylinder body is provided with fixed with described
The corresponding alignment pin of position pin-and-hole.
It as the improvement of technique scheme, is provided with outside described attachment for main bearing of engine during assembling
The mistake proofing boss interfering with described cylinder body when covering anti-loaded.
As the improvement of technique scheme, the attachment between two described bearing cap unit is provided with for engine oil baffle
The second installing hole connecting.
As the improvement of technique scheme, described attachment is provided with reinforcement.
Implement a kind of engine main bearing cover of the present utility model, compared with prior art, have the advantages that
Use integrated structure design, multiple bearing cap unit are connected integral, first, during mounting or dismounting, it is not necessary to aligned cylinder one by one
The installation position of body, it is not necessary to special disassembling fixture, makes bearing cap be more easily installed and dismantles；Secondly, main beating cap is reduced
Quantity, it is simple to part management；Again, reduce the quantity of alignment pin and dowel hole, reduce processing and assembly process, reduce into
This；Finally, can effectively strengthen the rigidity of main beating cap, reduce vibrating noise, improve the comfort level of car load.Additionally, this practicality is new
Type is also by the design of mistake proofing boss, it is ensured that the accuracy that bearing cap is installed.
Brief description
In order to be illustrated more clearly that the technical scheme of the utility model embodiment, simple by the accompanying drawing of embodiment is made below
Ground is introduced.
Fig. 1 is the structural representation of a kind of engine main bearing cover of the utility model；
Fig. 2 is the structural representation of another line of vision of a kind of engine main bearing cover of the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of the utility model protection.
Seeing shown in Fig. 1 and Fig. 2, preferred embodiment of the present utility model, a kind of engine main bearing cover, it includes multiple
Bearing cap unit 1 and the attachment 2 each bearing cap unit 1 being arranged in order and linking into an integrated entity.In the present embodiment, with 4
As a example by 5 bearing cap unit 1 of Cylinder engine, by clutch shaft bearing cap unit, the second bearing cap unit, the 3rd bearing cap unit,
4th bearing cap unit, the 5th bearing cap unit are arranged in order and are linked into an integrated entity by attachment 2.Each described bearing sheet
Unit 1 is connected with cylinder body, and described bearing cap unit 1 is provided with the connecting portion 11 of semi-circular structure, described connecting portion 11 be correspondingly provided with
The cylinder body of semi-circular structure connects the circular port being formed for bearing placement.The connecting portion 11 of described semi-circular structure has two connections
End, described connection end line centered on the axis of described circular port is symmetrical set, and described connection end is provided with for described cylinder body
The first installing hole 12 connecting.It is positioned at the side (inner side of structure as shown in fig. 1) of the described bearing cap unit 1a of head end
The first installing hole and the first of the opposite side (outside of structure as shown in fig. 1) of the described bearing cap unit 1b being positioned at tail end
Installing hole is dowel hole 12a, and this described cylinder body is provided with the alignment pin corresponding with described dowel hole 12a.Wherein, fixed
Position pin is 2, and bolt is 8.During assembling, alignment pin is arranged on cylinder body, then by the dowel hole 12a of bearing cap with determining
Position pin alignment is installed on cylinder body, it is ensured that the positional precision of bearing cap, is fixed on bearing cap on cylinder body finally by bolt.
Thus, use integrated structure design, multiple bearing cap unit 1 are connected integral, first, during mounting or dismounting, no
Need to be directed at one by one the installation position of cylinder body, it is not necessary to special disassembling fixture, make main beating cap be more easily installed and dismantle；Its
Secondary, reduce the quantity of main beating cap, it is simple to part management；Again, reduce the quantity of alignment pin and dowel hole 12a, reduce
Processing and assembly process, reduce cost；Finally, can effectively strengthen the rigidity of main beating cap, reduce vibrating noise, improve car load
Comfort level.
In order to ensure the accuracy that bearing cap is installed, outside described attachment 2 on mistake proofing boss 23, described mistake proofing are set
Boss 23 interferes with described cylinder body when anti-loaded for engine main bearing cover during assembling.If it is it is to say, fixed
Position pin-and-hole 12a exchanges, and the mistake proofing boss 23 of main beating cap design can be interfered with cylinder body, it is to avoid engine during assembling
There is anti-loaded phenomenon in main beating cap.
Attachment 2 between two described bearing cap unit 1 is provided with the second installing hole 21 connecting for engine oil baffle,
Thus provide installation site to engine oil baffle, facilitate engine oil baffle to install.
Described attachment 2 is provided with reinforcement 22, thus further enhances the rigidity of main beating cap.
Above disclosed only preferred embodiment of the present utility model, can not limit this practicality with this new certainly
The interest field of type, the equivalent variations therefore made according to the utility model claim, still belong to the utility model and covered
Scope.
