The detachable subframe that the utility model provides is divided into traditional integral type subframe leading portion support body and the back segment support body removably connecting, thereby facilitated the Assembly &Disassembly in maintenance process, and at maintenance process without changing whole subframe, effectively reduced service expenditure.
Accompanying drawing explanation
Fig. 1 is a kind of preferred detachable subframe schematic diagram of the utility model;
Fig. 2 is the decomposing schematic representation of the detachable subframe shown in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is described in detail.Wherein identical parts represent with identical Reference numeral.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric centre.
As depicted in figs. 1 and 2, the detachable subframe that the utility model provides comprises back segment support body 1 and the leading portion support body 2 being connected with described back segment support body 1, described back segment support body 1 is U-shaped, two free ends and the described leading portion support body 2 of described U-shaped are spirally connected, be spirally connected and can realize removably connecting of back segment support body 1 and leading portion support body 2, thereby in maintenance process, be easy to Assembly &Disassembly leading portion support body 2, and without changing whole subframe, reduced maintenance cost.
Leading portion support body 2 of the present utility model comprises hollow crossbeam 21, and the two ends of described hollow crossbeam 21 are fixedly connected with respectively hollow longeron 22, and wherein, the end of described hollow longeron 22 and described U-shaped 's free end is spirally connected.Hollow crossbeam 21 of the present utility model and hollow longeron 22 are made by hollow tube, compare with solid tubing, the conquassation better performances of hollow tube, therefore in the process bumping, can absorb preferably foreign impacts, thereby contribute to reduce the destruction of collision impact to back segment support body 1, in addition, hollow tubular can reduce the weight of subframe significantly, contribute to reduce the weight of car load, meet light-weight design needs.
As a kind of preferred version of the present utility model, as depicted in figs. 1 and 2, described hollow longeron 22 is arranged on the end of described hollow crossbeam 21 perpendicular to described hollow crossbeam 21.Two hollow longerons 22 of the present utility model are the angle in 90 ° with described hollow crossbeam 21 shapes preferably, improves significantly by this support performance of leading portion support body 2.Certainly, the utility model can also limit to adjust the angle between described hollow crossbeam 21 and described hollow longeron 22 according to the stressed needs of leading portion support body 2 and assembly space, repeats no more herein.On this basis, in order to reduce as much as possible the weight of subframe, described hollow longeron 22 is arranged on the two ends of described hollow crossbeam 21, thereby avoids introducing unnecessary material in subframe.
On the basis of above-described embodiment, in order to guarantee as much as possible the Joint strenght of hollow crossbeam 21 and hollow longeron 22, described hollow crossbeam 21 is welded to connect with described hollow longeron 22, and more preferably, described hollow crossbeam 21 and described hollow longeron are stitched together by cold arc-welding.What those skilled in the art should understand that is, be welded to connect is only that the present embodiment is for being fixedly connected with a kind of preferred version of hollow crossbeam and hollow longeron, the utility model can also adopt other fixed form with enough Joint strenghts conventionally known to one of skill in the art, repeats no more herein.
What those skilled in the art should understand that is, aluminium has that density is low, plasticity is just easy to by force the advantages such as welding, therefore, the utility model is adopted leading portion support body 2 and the back segment support body 1 of preferably preparing subframe with aluminium, not only can reduce the weight of subframe like this, can also facilitate the machine-shaping of leading portion support body 2 and back segment support body 1, reduce the difficulty of processing of subframe.
