In variable compression ratio engine, to be used for such as crankshaft, eccentric shaft, piston in variable compression ratio as carrying basis
And it is in linkage with the installing of the multi-connecting-rod mechanism between above-mentioned each component.The structure of the multi link formula variable compression ratio engine will be under
It is introduced in literary embodiment two, the present embodiment is mainly illustrated the structure of the engine cylinder body.
By Fig. 1 and as shown in connection with fig. 2, the engine cylinder body of the present embodiment is generally comprised using aluminium base material and by spiral shell
The upper cylinder body 1 and lower cylinder body 2 that bolt 4 connects, further include the insert 3 for inlaying the irony being fixed in lower cylinder body 2.Wherein, upper cylinder body 1
It is to divide formula structure equally with lower cylinder body 2, in being configured with mounting groove 501 under crankshaft in the top end surface of insert 3, in the bottom of insert 3
It is also configured with the eccentric shaft mounting hole 6 through setting, and the two sides of mounting groove 501 are respectively equipped with the spiral shell through arrangement under crankshaft
Bolt connecting hole 11, bolt 4 i.e. be arranged in bolt connecting hole 11, meanwhile, under crankshaft mounting groove 501 also be configured in upper cylinder body 1
The enclosing of mounting groove 502 constitutes crankshaft installed hole 5 on the crankshaft of bottom end face.
In the present embodiment, the crankshaft installed hole 5 collectively formed with mounting groove 502 on crankshaft by mounting groove 501 under crankshaft is i.e.
It is the rotation installing that the eccentric shaft mounting hole 6 installed for the rotation of crankshaft, and be formed in 3 bottom of insert is then used for eccentric shaft.
Upper cylinder body 1 and lower cylinder body 2 and insert 3 are to be formed by casting technique, and insert 3 is cast prior to lower cylinder body 2, and in lower cylinder
Insert 3 is placed in the mold of lower cylinder body 2 by body 2 when casting, so that be fixed with one after the completion of lower cylinder body 2 and the casting of insert 3,
To form complete inferior part of the cylinder block structure.
And the lower cylinder body 2 for aluminium base material is respectively adopted and the insert 3 using ferrous material, due to material between the two
Difference, and then when casting completes to carry out the fit processing of upper lower cylinder body, inevitably because of bi-material layers processing performance
Difference affects processing quality, processing efficiency and cutter life.As a result, to ensure in the processing of upper lower cylinder body zoarium,
Bi-material layers can be evaded and process more difficult problem, the present embodiment particularly makes the top end surface of insert 3 relative to lower cylinder body 2
Top end surface sinks to being arranged, and the outside of mounting groove 501 is coated with using aluminium base under crankshaft in the top end surface of insert 3
The clad 7 of matter.
The thickness of the clad 7 can be 2-3mm, and for example its can be 2mm, 2.2mm, 2.5mm, 2.7mm or 3mm, with
The clad 7 of the aluminium base material is cut in processing.And the upper cylinder body 1 for being all made of aluminium base material, lower cylinder
Body 2 and clad 7, the present embodiment aluminium base material may be, for example, aluminium base ZL106, and cast iron then for example can be used in the insert 3 of irony
QT600-3.In addition, SCM435 then can be used in the bolt 4 for the connection of upper and lower housing structure, and 12.9 grades are specifically chosen, with energy
Enough reach the Tightening moment requirement of cylinder body.

Also the insert groove 10 of indent setting is configured on the end face that body 2 connects, which can be as shown in Fig. 1 or 2
Circle, and the position corresponding to the insert groove 10 of lower cylinder body 2 is also to be embedded in insert groove 10 as can be seen in the figure.
As a result, by insertion of 2 part-structure of lower cylinder body in insert groove 10, lower cylinder body 2 and the faying face of insert 3 is made to produce machine
Tool interlocking prevents the problem of loosening between the two so as to reach.
Certainly, it to further increase the stability that insert 3 is connect with lower cylinder body 2, when lower cylinder body 2 is cast, also may be selected
Frosting treatment is carried out to the outer surface of insert 3, the fixing that insert 3 is connected with 2 faying face of lower cylinder body is increased with this.On at this point,
It states frosting treatment for example and the techniques such as electrochemical process, shot-peening method, high-energy-rate stream irradiation or spark discharge can be used.
The present embodiment referring also to shown in Fig. 1 and Fig. 2, in the top end surface of insert 3 under crankshaft mounting groove 501 side
It is also equipped with the locating piece 8 that one end is fixed in insert 3, and also interference is plugged in upper cylinder body 1 other end of the locating piece 8.
Wherein, hollow cannula structure for example can be used in above-mentioned locating piece 8 or solid column structure, Er Qieding can also be used in it
One end that position part 8 is connected with insert 3 preferably can be to be fixed in insert 3, can make to position in such a way that interference is pressed
Part 8 is assembled again after 2 surface completion of processing of lower cylinder body, and thus, it is possible to avoid processing 2 surface of lower cylinder body impacting.
In the present embodiment, the magnitude of interference between locating piece 8 and insert 3 and upper cylinder body 1 can be between 0.3-0.5mm, and leads to
The setting for crossing locating piece 8 not only increases the contact area and bearing strength of insert and upper cylinder body, while it can also share and start
The shearing force generated in machine operation, and then guarantee the reliability of upper lower cylinder body connection.And in addition to locating piece 8, the present embodiment is being inlayed
The guide part 9 that one end is equally fixed in insert 3 is additionally provided in the top end surface of block 3, the guide part 9 be specially and locating piece
8 two sides for being placed in crankshaft installed hole 5, and the other end of guide part 9 is then inserted in upper cylinder body 1 and constitutes between upper cylinder body 1
Clearance fit.
Different from the setting of locating piece 8, the setting of the guide part 9 of the present embodiment is then used to prevent up and down when cylinder body assembles
Position deviation is excessive between cylinder body, in favor of the progress of assembly work.But similar with the structure of locating piece 8, which is having
Hollow cannula structure can also be used in body when implementing or it also can be solid column structure, and guide part 9 is preferably also adopted
It is fixed in insert 3 with the mode that interference is pressed, magnitude of interference still takes numerical intervals above.
The engine cylinder body of the present embodiment can meet cylinder body light weight by making upper cylinder body 1 and lower cylinder body 2 use aluminium base material
The requirement of change, and the insert 3 that setting is irony is inlayed by setting, and bolt 4 is set in insert 3, also can adapt to
The larger situation of 4 fastening force of bolt, so as to overcome lightweight possessed by engine cylinder body in the prior art and bolt
Tightening moment is difficult to greatly the deficiency met simultaneously, and has preferable practicability.
