Abstract
The utility model provides a car aluminum alloy subframe, car aluminum alloy subframe has the cavity that is used for installing the engine, be equipped with the installation base in the cavity, the cross -section of installation base is reduced by the outside to inboard gradually, just the inner wall all around of cavity has the pattern draft. The utility model discloses car aluminum alloy subframe adopts the engine support mounting point of the preceding subframe of aluminum alloy of novel structure, can avoid using the psammitolite molding to make, and effective reduce cost is and can effectively improve the mechanical properties of engine support mounting point, and wide application can be promoted in aluminum alloy subframe structural design to this kind of structure.
Description
Technical field
The utility model relates to automotive field, particularly aluminium alloy car subframe.
Background technology
At automotive field, subframe is the skeleton of vehicle bridge always, as one of the important component part of vehicle bridge.Wherein, the effect of fore sub frame intercepts vibration & noise, reduces it and directly enter compartment.In addition, in order to adapt to the high request of nowadays car traveling comfort, subframe substantially all loaded onto by existing car.This suspension assembly with subframe, is not only designing, is installing and can bring various convenience and preceence, and the most important thing is also to make its traveling comfort and suspension stiffness be improved.
But structurally still there are some inconveniences in traditional aluminum alloy auxiliary vehicle frame.Such as, conventional aluminum alloy subframe often adopts core mould, when finally that core is shatter after aluminium liquid cooling forming when manufacturing the structure with the cavity of horizontal direction.
Fig. 1 is the structural representation of engine bed attachment point in orthodox car aluminum alloy auxiliary vehicle frame.As shown in Figure 1, the cavity structure A of the engine bed attachment point of aluminum alloy auxiliary vehicle frame 10 is exactly the produced structure of typical core mould.Its constructional feature is: the heart has an isolated installation base 11 in the cavities, and it does not extend to the inwall of cavity, does not have the feature of " outer low and inner high ", therefore just has no idea to use metal mould forming.
In addition, the cavity pore-solids ratio also more difficult control of core mold forming, than the bad mechanical property of metal paattern, cost is also high.
Utility model content
The technical problems to be solved in the utility model adopts cavity pore-solids ratio difficulty to control to overcome aluminum alloy auxiliary vehicle frame in prior art, and the defect of bad mechanical property, provides a kind of aluminium alloy car subframe.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of aluminium alloy car subframe, its feature is, described aluminium alloy car subframe has the cavity for installing driving engine, installation base is provided with in described cavity, the cross section of described installation base is reduced to inner side gradually by outside, and the surrounding inwall of described cavity has pattern draft.
Preferably, the surrounding inwall of described cavity has the pattern draft of 3 °.
Preferably, the rear of described installation base is provided with one and dodges perforate.
Preferably, the width of dodging perforate described in is equal with the width of described installation base.
Preferably, the metal-cored mold forming of perforate by a vertical direction is dodged described in.
Preferably, be provided with boss extension between the rear of described installation base and the inwall of described cavity, described boss extension connects the inwall of described installation base and described cavity.
Positive progressive effect of the present utility model is: the utility model aluminium alloy car subframe adopts the engine bed attachment point of the aluminum alloy fore sub frame of new structure, can avoid using core to be molded to make, effectively reduce costs and effectively can improve the mechanical characteristics of engine bed attachment point, this kind of structure can be promoted and be widely used in the design of aluminum alloy auxiliary body frame structure for automotive.
Accompanying drawing explanation
The above and other feature of the utility model, character and advantage are by more obvious by what become below in conjunction with the description of drawings and Examples, and Reference numeral identical in the accompanying drawings represents identical feature all the time, wherein:
Fig. 1 is the structural representation of engine bed attachment point in orthodox car aluminum alloy auxiliary vehicle frame.
Fig. 2 is the block diagram of the utility model aluminium alloy car subframe.
Fig. 3 is the birds-eye view of the utility model aluminium alloy car subframe.
Fig. 4 is along the cutaway view that B-B line is cut open in Fig. 3.
Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.
Fig. 2 is the block diagram of the utility model aluminium alloy car subframe.Fig. 3 is the birds-eye view of the utility model aluminium alloy car subframe.Fig. 4 is along the cutaway view that B-B line is cut open in Fig. 3.
As shown in Figures 2 to 4, one of the present utility model embodiments provides a kind of aluminium alloy car subframe 20, and it has the cavity 21 for installing driving engine, is provided with installation base 22 in cavity 21.Especially, the cross section of installation base 22 is reduced to inner side gradually by outside, and the surrounding inwall of cavity 21 has pattern draft.The surrounding inwall of cavity 21 preferably has the pattern draft (not shown) of 3 °.
This structure makes the installation base 22 in the utility model aluminium alloy car subframe not be isolated in cavity 21, and the inwall of itself and cavity 21 has coherent structure, and integral structure has significantly " outer low and inner high " feature.
Further, the rear of installation base 22 is provided with one and dodges perforate 24.The width of dodging perforate 24 is equal with the width of installation base 22.Because driving engine operationally has vibrations, easily cause engine mounting bracket to have slight vertical tremor trend, in order to prevent interfering, therefore having done one in the back of installation base 22 and large having dodged perforate 24.Here perforate 24 of dodging can by the metal-cored mold forming of a vertical direction.
Preferably, between the rear of installation base 22 and the inwall of cavity 21, be provided with boss extension 23, boss extension 23 connection boss 22 herein and the inwall of cavity 21.
In sum, the utility model aluminium alloy car subframe adopts the aluminum alloy fore sub frame engine bed attachment point of said structure, effectively can avoid using core to be molded to make, effectively reduce costs, and effectively can improve the mechanical characteristics of engine bed attachment point.This structure can be promoted and be widely used in the structure design of aluminium alloy car subframe.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
