Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality such as " inside and outside " of use refers to the interior and outer of corresponding component profile.
As shown in Figures 2 and 3, the utility model provides a kind of engine mounting support arm, comprise the suspension body 10 for being connected on driving engine, this suspension body 10 is provided with the connecting arm 20 for being connected on vehicle body, for reducing the wall thickness of connecting arm 20, realizing loss of weight demand simultaneously, this connecting arm 20 being formed with the hole 200 that the length direction along this connecting arm 20 extends, wherein, the outline of the cross-sectional plane in hole 200 has the convex section 201 and depression section 202 that alternately connect.
Wherein, it should be noted that, hole 200 relative to engine mounting support arm generally, is a blind hole; and relative to connecting arm 20; can be blind hole, also can be through hole, in other words; hole 200 can through whole connecting arm 20; also only can extend to a part for connecting arm 20, the utility model is not restricted this, all belongs among protection domain of the present utility model.Usually, for making the structural strength of connecting arm 20 more reliable, hole 200 extends to the stress maximum region of connecting arm 20.
Therefore, the outline of the cross-sectional plane in hole 200 is designed to the convex section 201 alternately connected and the section 202 that caves in, like this, the depression section 202 that the inner surface of connecting arm 20 is formed can reduce the thickness of engine mounting support arm, in addition, from the distance between the two-end-point of this convex section 201 namely the thickness of convex section 201 be, be the width of convex section 201 in fig. 2, the two is all less than the thickness of the connecting arm 20 in prior art corresponding to circular port, thus reduce the porosity of cast aluminium, simultaneously, the convex section 201 that the inner surface of connecting arm 20 is formed can strengthen the structural strength of connecting arm 20, namely the effect of reinforced rib is played, effectively can reduce the stress in support arm and driving engine coupling end region, and then improve the fatigue life of engine mounting support arm.
The outline of the cross-sectional plane in hole 200 can be partly the convex section 201 alternately connected and the section 202 that caves in, and another part can be circular arc, for reducing the porosity of cast aluminium further, reduce the stress in support arm and driving engine linkage section region, the outline of the cross-sectional plane in hole 200 is alternately formed by multiple convex section 201 and multiple depression section 202 simultaneously.That is, hole 200 is formed as Hua Xingkong.
