Detailed description of the invention
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 3-4, the mounting bracket of a kind of Lower suspension arm of automotive suspension that the utility model embodiment provides, comprises the first side plate 21, second side plate 22, rebound 23 and pipe 25.Described first side plate 21, second side plate 22 is connected with subframe longitudinal beam 02, thus makes a subassembly in mounting bracket formation subframe assembly.Above-mentioned rebound 23 is welded between the first side plate 21 and the second side plate 22, and rebound 23 has circular hole, and described pipe 25 is fixed in circular hole.One end of lower swing arm 03, through above-mentioned pipe 25, is connected with the rubber bush 05 in pipe 25 by bolt, nut and limiting gasket group 06, and rubber bush 05 and pipe 25 inwall are interference fit, thus play connection function.The feature of this structure is, the first side plate 21 contacts with curved of at least one in the second side plate 22 and rebound 23, and arrange the portion deforms amount that rear mounting bracket plays a transition role like this and reduce, transition is more smooth-going.When mounting bracket bearing load, the weld of rebound 23 and the first side plate 21, second side plate 22, and on the first side plate 21, second side plate 22 side plate bending crushed element distribution of stress evenly.Compared to the content introduced in background technology, the mounting bracket load-carrying capacity that the utility model provides is stronger.
In addition, on mounting bracket provided by the utility model, be flaring structure 24 for press-fiting at least one end port of the pipe 25 of rubber bush 05, the enlarging of this flaring structure 24 facing to the outside of pipe 25, the position beyond the inner chamber referring to pipe 25 outside this.In installation process, one end of rubber bush 05 is aimed at enlarging face and is loaded, and flaring structure 24 has guiding function, can make rubber bush 05 and the line of centers automatic reclosing of pipe 25, press-fit more convenient.
For ease of illustrating, first mounting bracket is divided into Part I and Part II along axial plane in the level of pipe 25, described Part II is vertically positioned at the below of Part I.In the utility model embodiment, first side plate 21 with at least one in the second side plate 22 with rebound 23 curved part contacted, have the edge extending to Part II side, namely the first side plate 21 and/or the second side plate 22 pairs of rebounds 23 have supporting role straight up.Object main is herein, alleviates lower swing arm 03 under gravity on the impact that above-mentioned Part II causes.Certainly do not get rid of the structure that other may play above-mentioned effect, such as, the part simultaneously making the arcwall face of Part I side contact, has the trend of K/UP, can play a supporting role equally to rebound 23.The trend of described K/UP not necessarily straight up, as long as support component upwards can be produced to rebound 23.
In the utility model embodiment, the first side plate 21 or the second side plate 22 extend to the edge of described Part II, cross the vertically middle axial plane of pipe 25.The first side plate 21 or the second side plate 22 and rebound 23 area of contact in Part II side can be increased like this, improve mounting bracket further to the supporting role of lower swing arm 03, better reliability; On the other hand, this asymmetric structure is more conducive to meeting the status requirement between lower swing arm 03 and subframe longitudinal beam 02, is convenient to the side at mounting bracket tendency lower swing arm 03 place.
In the utility model embodiment, the first side plate 21 is not connected with the second side plate 22, and namely both are two separate parts.When complicated structure, its manufacturability is better, be convenient to processing.
Certainly, from the viewpoint of raising structural behaviour, also the first side plate 21 and the second side plate 22 can be arranged to integral type, such as, directly form with one piece of plate bending or incite somebody to action both weld togethers.Compared to the scheme be provided separately, the shortcoming that this programme may exist is processed plate excessive being unfavorable for, can select as the case may be in the middle of practical application.
In said structure, rebound 23 can be arranged to single or multiple, and single rebound 23 can choose raw-material thickness according to structure size, with the requirement of the aspects such as commensurate structure intensity.If adopt the situation of multiple rebound 23, the thin plate of same thickness can be selected to process, multiple described rebound 23, along the axial distribution of pipe 25, leaves certain interval between each plate.Compared to the situation of single rebound 23, the latter can save material, alleviate mounting bracket own wt, can set again the quantity of above-mentioned spacing distance and rebound 23, make structure distribution more reasonable according to actual loading situation.Therefore, be more prone in the middle of the utility model embodiment adopt rear a kind of scheme.
Above-mentioned first side plate 21 and/or the second side plate 22 can also set up reinforced rib 27, consider that the first side plate 21 is stressed more concentrated with the part that the second side plate 22 contacts with rebound 23, reinforced rib 27 can be made to extend to two ends along the edge of rebound 23, better play stiffening effect.Concrete, reinforced rib 27 can directly on plate punching press obtain, also can on relevant position, weld a block of material realize.
In the middle of practical application, when the application force that mounting bracket bears is larger, also can increase the quantity of above-mentioned reinforced rib 27, to improve structural strength further.Multiple reinforced rib 27 and rebound 23 can distribute alternately, thus better play the effect of each reinforced rib 27, make integral structure stressed evenly.
Further, the edge of above-mentioned first side plate 21 and/or the second side plate 22 forms turnup structure 26, and turnup structure 26 can increase the structural strength of plate, thus improves the load-carrying capacity of mounting bracket.
The utility model embodiment still provides a kind of automotive suspension, comprises the mounting bracket 07 described in above-mentioned any one.Because the lower swing arm mounting bracket of above-mentioned automotive suspension has above-mentioned technique effect, the automotive suspension comprising this mounting bracket also should have corresponding technique effect.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
