Embodiment
The embodiment of the disclosure is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explained the disclosure, is not limited to the disclosure.
In the disclosure, in the case where not making opposite explanation, the noun of locality such as " interior " " outer " used is to be directed to corresponding zero
For profile of part itself, " top " " bottom " is for the page of respective drawings.
As shown in figure 1, engine link generally includes major part 21, microcephaly 22 and shaft 23, shaft 23 and major part 21 with
And transition arc is formed respectively between microcephaly 22, so that connecting rod has enough intensity.As shown in Fig. 2 the hair that the disclosure provides
In motivation connecting rod, the bottom of major part 11 could be formed with the Ministry of worker to be added, can remove the material of connecting rod from the bottom of major part 11.
Here, the bottom of major part 11 refers to the bottom of page corresponding to Fig. 1 and Fig. 4, that is, Fig. 4 respective views look up diagram
The position gone out.So, after connecting rod is forged waits technological forming, if blank weight is excessive, it is difficult to meet the light of engine
Quantization requires, can be processed further in the position of the Ministry of worker to be added, such as one plane of milling, mitigates the weight of blank, from
And reduce the percent defective of connecting rod.The Ministry of worker to be added is set in the bottom of major part 11, does not interfere with the overall construction intensity of connecting rod, and phase
Compared with microcephaly 12 and shaft 13, major part 11 has enough installation spaces.In addition, the Ministry of worker to be added can be also used for balanced connecting rod
Center of gravity, according to the physical location of shaping back link center of gravity, the position of center of gravity can be finely tuned by being processed the Ministry of worker to be added at so that
Obtain connecting rod and meet design requirement.
Specifically, the Ministry of worker to be added can include forming the processing plane 16 in the bottom end face of major part 11, process plane 16
, so, can be in machining plane 16, it is ensured that connecting rod perpendicular to the axis of connecting rod, the i.e. above-below direction perpendicular to Fig. 1
Center of gravity moved along parallel to the direction of axis.Further, as shown in Fig. 2 processing plane 16 can be located at major part 11
Bottom end face center, so, when carrying out Milling Process to processing plane 16, the plane after processing can be located at major part 11 all the time
End face center position, it is ensured that overall structure is symmetrical, uniform force, and the center of gravity of connecting rod can be always positioned on its axis.
Further, as shown in figure 4, the outside of transition arc 14 between major part 11 and shaft 13 in the disclosure can be with
It is provided with reinforcement 15.So, transition arc 14 can be designed as to have less arc chord angle, the weight of connecting rod can be mitigated
Amount, meanwhile, reinforcement 15 can ensure the bulk strength of connecting rod.That is, the engine link that the disclosure provides can be whole in guarantee
Mitigate weight while body intensity, and then improve the service life of engine.
Specifically, reference picture 4, reinforcement 15 extend from shaft 13 towards major part 11, i.e. so that reinforcement 15 and transition circle
The bearing of trend of arc 14 is essentially identical, stabilized structure.In addition, reinforcement 15 is located at the center of the thickness direction of shaft 13, it is ensured that
The symmetrical configuration of connecting rod, the thickness of reinforcement 15 can be the 1/2 to 1/4 of the thickness of shaft 13, and the disclosure is not limited specifically this
It is fixed.It is substantially similar with the overall structure of the connecting rod in the correlation technique for example shown in 1 to be provided with the bar linkage structure after reinforcement 15,
The side of reinforcement 15 can also be formed as arc-shaped, corresponding with the transition arc outline in correlation technique, i.e. equivalent to right
Former transition arc does loss of weight processing, the bulk strength without destroying connecting rod.For example, in the related art, the transition at major part 11
The radius of circular arc 14 is 49.7mm, and after setting reinforcement 15, the radius of transition arc 14 can greatly reduce, and is, for example,
20mm, now, the radius of the reinforcement 15 of arc-shaped so, can have close to 49.7mm while the intensity of connecting rod is ensured
Its weight is alleviated to effect, meets the light-weighted design concept of engine.
Further, as shown in figure 3, the thickness of microcephaly 12 gradually becomes from it close to one end of shaft 13 to its top end face
It is small, to mitigate the weight of microcephaly 12, so as to so that connecting rod loss of weight.Because the part of the force of microcephaly 12 is concentrated mainly on its bottom
Portion reduces the top thickness of microcephaly 12 weight that can mitigate connecting rod while its intensity is ensured close to the position of shaft 13
Amount.It should be noted that the thickness that the disclosure refers to is the habitual description definition according to connecting rod, specifically referring in Fig. 3
Drawing left and right directions.
When the major part 11 of connecting rod is provided with above-mentioned reinforcement 15, or microcephaly 12 does loss of weight processing as above, or the two
When making the improvement referred in the disclosure, the center of gravity of connecting rod can be affected and offset, at this point it is possible to by the Ministry of worker to be added,
The center of gravity of the processing balanced connecting rod of plane 16 as escribed above.
Further, the embodiment shown in reference picture 3, microcephaly 12 can be formed as wedge shape so that the thickness of microcephaly 12
It can be tapered into from it close to the position of shaft 13, uniform force.
The above-mentioned wedge-shaped angle of wedge can be 18 ° -25 °, and weight loss effect is bad during angle too small, causes when angle is excessive small
First 12 top end thickness is too small, and the angle of wedge can be depending on the overall actual size of connecting rod, to meet that difference is started
The weight demands of machine, the disclosure are not particularly limited to this, such as rule of thumb, can be designed as 21 °, can either ensure connecting rod
Intensity, it is ensured that engine stabilizer works, and can also play the purpose of loss of weight.
Alternatively, as shown in figure 3, two inclined-planes of wedge shape are symmetrically arranged at the axis both sides of connecting rod, microcephaly's 12
Side is formed as the shape of approximate isosceles trapezoid as shown in Figure 3 so that each height of microcephaly 12 uniform force at work.
The disclosure also provides a kind of engine and is provided with the vehicle of the engine, wherein, engine includes piston, song
Axle and the connecting rod being connected between piston and bent axle, connecting rod are above-mentioned engine link.It is provided with the hair of above-mentioned connecting rod
Motivation has the advantages of service life length, reliable.Using the vehicle manufacture cost of the engine is low, oil consumption is small.
The preferred embodiment of the disclosure is described in detail above in association with accompanying drawing, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out to the technical scheme of the disclosure
Monotropic type, these simple variants belong to the protection domain of the disclosure.
It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance
In the case of shield, can be combined by any suitable means, in order to avoid unnecessary repetition, the disclosure to it is various can
The combination of energy no longer separately illustrates.
In addition, it can also be combined between a variety of embodiments of the disclosure, as long as it is without prejudice to originally
Disclosed thought, it should equally be considered as disclosure disclosure of that.
