For realizing above-mentioned object, the utility model has adopted following technological scheme:
A kind of connecting rod, described connecting rod comprises major part, microcephaly and shaft, and described microcephaly is provided with the through hole for wrist pin is installed, described microcephaly has the longitudinal section diminishing gradually towards its top on the length direction of described connecting rod, and the joint of described microcephaly and described shaft is also provided with jut.
In above-mentioned connecting rod, preferably, described longitudinal section is wedge shape.
In above-mentioned connecting rod, preferably, described microcephaly has the first inclined-plane and the second inclined-plane, and the angle of the medial axis of described the first inclined-plane and described the second inclined-plane and described connecting rod is respectively between 8 degree to 15 degree.
In above-mentioned connecting rod, preferably, described the first inclined-plane and described the second inclined-plane are arranged symmetrically with along the medial axis of described connecting rod.
In above-mentioned connecting rod, preferably, described jut has rectangular cross section.
In above-mentioned connecting rod, preferably, the length of described jut on the axial direction of described through hole is between 1 centimetre to 3 centimetres.
In above-mentioned connecting rod, preferably, the extreme length of the described longitudinal section that the length of described jut on the axial direction of described through hole is greater than described microcephaly on the axial direction of described through hole.
A kind of motor, described motor is provided with above-mentioned connecting rod.
In above-mentioned motor, preferably, described motor is direct fuel-injection engine or supercharged engine.
A kind of automobile, described configuration of automobiles has above-mentioned motor.
Difference with the prior art is that connecting rod of the present utility model has not only reduced the weight of connecting rod self effectively, and has significantly improved the intensity of connecting rod small end, and then has reduced the oil consumption of motor, and has extended the life-span of motor.
Brief description of the drawings
Below with reference to drawings and Examples, the technical solution of the utility model is described in further detail, but it should be known that these accompanying drawings are only for task of explanation designs, therefore not as the restriction of the utility model scope.
Fig. 1 is the longitudinal section schematic diagram of the connecting rod with rectangle microcephaly of prior art.
Fig. 2 is the longitudinal section schematic diagram of the connecting rod with wedge shape microcephaly of prior art.
Fig. 3 is an embodiment's of connecting rod of the present utility model cross sectional representation.
Fig. 4 is the longitudinal section partial schematic diagram of the connecting rod in Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.Should be understood that, the detailed description of specific embodiment is used for to description and interpretation the utility model, but is not limited to the utility model.
Refer to Fig. 3, it schematically illustrates the schematic diagram of the cross section of connecting rod of the present utility model.This connecting rod 1 comprises microcephaly 2, major part 3 and shaft 4, and this microcephaly 2 is provided with the through hole 5 for wrist pin is installed, and for object clearly, does not draw out wrist pin herein.From Fig. 4, can be clear that, microcephaly 2 has the longitudinal section diminishing gradually towards the top of connecting rod 1 on the length direction of connecting rod 1, to alleviate microcephaly 2 weight, and has also alleviated thus the gross weight of connecting rod 1.In addition, microcephaly 2 is also designed with jut 6 with the joint of shaft 4, thereby ensures structural strength and the safety coefficient of connecting rod 1 at microcephaly's 2 stressed biggest places in one end.
From the preferred embodiment shown in Fig. 4, the microcephaly 2 of connecting rod 1 has the longitudinal section that is wedge shape, and microcephaly 2 has the first inclined-plane 7 and the second inclined-plane 8, the angle of this first inclined-plane 7 and the second inclined-plane 8 and whole connecting rod 1 medial axis (not shown) in the longitudinal direction can be separately positioned between 8 degree to 15 degree scopes.Alternatively, the first inclined-plane 7 is arranged symmetrically with into the shape (seeing Fig. 4) that makes microcephaly 2 longitudinal section substantially be isosceles trapezoid along the medial axis of connecting rod 1 with the second inclined-plane 8.It is pointed out that alleged " cross section " refers to the plane intercepting on the radial plane of through hole 5 on the length direction of connecting rod 1 herein, can imagine, this cross section can be parallel to the plane of connecting rod 1 in the time doing plane motion, as shown in Figure 3; And " longitudinal section " refers to the cross section perpendicular to " cross section " on the length direction of connecting rod 1, therefore, this longitudinal section can be through the axis of through hole 5, as shown in Figure 4.
Incorporated by reference to consulting Fig. 3 and Fig. 4, jut 6 can have roughly rectangular longitudinal section again, and can have certain die forging inclined-plane 9,10 and be beneficial to the depanning of connecting rod 1, illustrates in the drawings with the form of exaggeration.In the present embodiment, the length of jut 6 on the axial direction of through hole 5 at 1 centimetre between 3 cm range, the extreme length of the longitudinal section that wherein length of jut 6 on the axial direction of through hole 5 can be designed to be greater than microcephaly 2 on the axial direction of through hole 5.It will be appreciated by those skilled in the art that, have microcephaly 2 under the situation of longitudinal section of convergent, adopt the rectangular design of widening at the stressed larger part of microcephaly 2 (being the joint of microcephaly 2 and shaft 4 in connecting rod 1), make whole connecting rod 1 not only reach loss of weight object but also ensured requirement of strength.Certainly, the shape of jut 6, size also can be according to different situation designs, to meet the actual demand of different motors.
In sum, connecting rod of the present utility model has ensured the intensity of connecting rod small end in reducing weight, makes the overall structure of connecting rod more reasonable.This type of optimal design of connecting rod not only improves the performance parameter such as pressure of explosion and power moment of torsion of motor, and has further increased service life of aeroengine, and makes motor operation more reliable.While it is emphasized that direct fuel-injection engine that this connecting rod is had relatively high expectations in outburst or supercharged engine application, effect is especially obvious.Obviously, can predict, of the present utility model when being provided with the motor of this connecting rod and disposing the automobile of this motor when applying on automobile, just can obtain such as in low cost of manufacture, save oil consumption, alleviate the good result of the aspects such as engine weight.
More than enumerate some specific embodiments and illustrated in detail connecting rod of the present utility model, be provided with the motor of this connecting rod and dispose the automobile of this motor, these a few examples are only for explanation principle of the present utility model and mode of execution thereof, but not to restriction of the present utility model, in the situation that not departing from spirit and scope of the present utility model, those of ordinary skill in the art can also make various distortion and improvement.Therefore, all technological schemes that are equal to all should belong to category of the present utility model also by every claim of the present utility model is limited.
