In the present embodiment, front cross rail 5 two ends are upwards welded with left connector 3 and right connector 7 respectively, after cross member 11 two ends are respectively equipped with left connecting arm 12 and the right connecting arm 10 (as shown in Figure 7) of K/UP, upper left longitudinal tubule (L tubule) beam 2 is fixedly connected with between the end of left connector 3 and the end of left connecting arm 12, upper right longitudinal tubule (L tubule) beam 8 is fixedly connected with between the end of right connector 7 and the end of right connecting arm 10, so just lower-left longitudinal tubule (L tubule) beam 4 and upper left longitudinal tubule (L tubule) beam 2 can be linked together, bottom right longitudinal tubule (L tubule) beam 6 and upper right longitudinal tubule (L tubule) beam 8 are linked together.
As shown in Figure 4, brace panel 13 and front cross rail 5 fit tightly, and brace panel 13 is welded on the Outboard Sections of the through hole 501 of front cross rail 5.That is, just welded brace panel 13 in stressed larger position, so arranged, can not only play and strengthen front cross rail 5 transverse strength and rigidity, material, expendable weight can also be saved, reduce costs.
As shown in Figure 1-Figure 3, between lower-left longitudinal tubule (L tubule) beam 4 and upper left longitudinal tubule (L tubule) beam 2, be welded with left installation bracket 1, between bottom right longitudinal tubule (L tubule) beam 6 and upper right longitudinal tubule (L tubule) beam 8, be welded with right mounting bracket 9.Two mounting brackets are used for installing driving engine, make driving engine be suspended on subframe by two mounting brackets, and structure is simple, easily realizes.
Wherein, left installation bracket 1 comprises the left support plate 101 and left support body 102 that are used for fixing connecting engine, as shown in Figure 5; Right mounting bracket 9 comprises the right support plate 901 and right support body 902 that are used for fixing connecting engine, as shown in Figure 6; Wherein, left support body 102 and right support body 902 are the tubular casing structure that a kind of circumference is closed, in the present embodiment, left support body 102 and right support body 902 are all the cross-sectional planes surrounded by one flat plate and the U-shaped plate being welded on dull and stereotyped both sides is approximate rectangular housing structure, and left support body 102 and left support plate 101 weld together, right support body 902 and right support plate 901 weld together; Left support plate 101 is welded on upper left longitudinal tubule (L tubule) beam 2, and right support plate 901 is welded on upper right longitudinal tubule (L tubule) beam 8, and left support body 102 is welded on lower-left longitudinal tubule (L tubule) beam 4, and right support body 902 is welded on bottom right longitudinal tubule (L tubule) beam 6.This kind of supporting body structure, can not only meet its intensity and rigidity requirement, also has handling ease and the light advantage of quality.
As shown in Figure 6, the supporter of right mounting bracket 9, namely the lower end of right support body 902 is vertically welded on bottom right longitudinal tubule (L tubule) beam 6, so arranges, and is conducive to strengthening the dynamic stiffness of engine mounting attachment point place along two crossbeam length directions.
In order to strengthen the intensity of driving engine attachment point, first by two supporter welding fabrications, then can weld with two longitudinal tubule (L tubule) beams respectively.
As shown in Fig. 1, Fig. 5 and Fig. 6, left support plate 101 is along upper left longitudinal tubule (L tubule) beam 2, right support plate 901 is all not less than 50mm along the length value of upper right longitudinal tubule (L tubule) beam 8 length direction, its length value too young pathbreaker's out of reach driving engine attachment point along the dynamic stiffness requirement of upper left longitudinal tubule (L tubule) beam 2 or the length direction along upper right longitudinal tubule (L tubule) beam 8, therefore in the present embodiment, such as, this length value is selected 61mm, or other sizes.
In the present embodiment, front cross rail 5 and after cross member 11 are the cylindrical shell structure that circumference is closed, after cross member 11 is a kind of cross sectional shapes formed by base plate and arc plate weld together is semi-round cylindrical shell structure, as shown in Figure 7 and Figure 8, first base plate and arc plate can snap together by the after cross member 11 of this kind of structure, and then weld, in addition, the sectional area of the after cross member 11 of this kind of cross sectional shape is maximum, therefore enables after cross member 11 rigidity along its length reach maximum; The cylindrical shell structure of front cross rail 5 to be a kind of cross sectional shapes formed by base plate and U-shaped plate weld together be rectangle.Two crossbeams all can adopt hydroforming process to make hollow shell structure, and whole subframe is had, and quality is light, structure is simple, integral structure bending resistance and the large advantage of torsion stiffness, especially can strengthen the rigidity along two crossbeam length directions.
In order to absorb the vibrational energy under larger collision, as shown in Figure 1, lower-left longitudinal tubule (L tubule) beam 4, bottom right longitudinal tubule (L tubule) beam 6, upper left longitudinal tubule (L tubule) beam 2 and upper right longitudinal tubule (L tubule) beam 8 are equipped with energy-absorbing groove, such as, in the present embodiment, upper left longitudinal tubule (L tubule) beam 2 is provided with left energy-absorbing groove 201, and upper right longitudinal tubule (L tubule) beam 8 is provided with right energy-absorbing groove 801, certainly, two lower longitudinal tubule (L tubule) beams are also provided with energy-absorbing groove, just not in diagram display.When the impact force that vehicle is subject to is larger, energy-absorbing groove will be preferential by vibration energy absorption, and degeneration occurs other position early than subframe, thus avoids significant points to be damaged, and avoids impact force to be delivered in operator's compartment, ensures the personal safety of navigating mate.
As shown in Figure 1-Figure 3, the end of upper left longitudinal tubule (L tubule) beam 2 and upper right longitudinal tubule (L tubule) beam 8 and after cross member 11 junction all downwards and be bent outwardly.
Need it is to be noted that subframe in the present embodiment, to adopt between each parts and each parts and be welded and fixed connection, also other can be adopted to be fixedly connected with mode, such as: adopt and be threaded or interference fit etc., certainly, also can adopt integral type machine-shaping.
