Abstract
The utility model provides an automotive rear upper control arm to solve the technical problems. The automotive rear upper control arm is lightweight and capable of solving the problem of motion interference of a suspension system. The automotive rear upper control arm comprises a bent control arm body and is characterized in that the control arm body is formed by stamping a steel plate and comprises a bottom wall and two side walls connected with the bottom wall, free sides of the two side walls are provided with flangings to enable the cross section of the arm body to be pi shaped, and a sleeve is welded to one end of the control arm body while the other end of the control arm body is in a structure that the bottom wall is open and two side walls are opposite mutually and provided with mounting holes to be convenient for connection with a steering knuckle, and a reinforcing plate is further connected between the two side walls of the control arm body.
Description
Technical field
The utility model relates to rear top control arm of automobile.
Background technology
Rear upper suspension arm is called again outward camber bar, is used for many link lever rear suspensions, and two ends connect respectively Rear secondary frame for vehicle and steering swivel, is two power bar structures, meets stiffness index and the requirement of strength of flare bar two ends point of connection under its designing requirement minimum mass condition.As depicted in figs. 1 and 2, Fig. 1 is left and right sheet welded structure to common flare bar linkage structure form, and Fig. 2 is upper suspension arm after forged steel form.Because structure design of automobile is more and more compacter, spring holder and shock strut are separate in addition, so traditional straight-bar type Control arm is due to movement interference problem, tend to cause movement interference, cannot meet design requirement.Even if the flare bar of warp architecture form can meet movement interference problem, but meets after performance requriements, quality often lays particular stress on.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rear top control arm of automobile, its lighter weight, and can meet the movement interference problem of suspension system.
For solving the problems of the technologies described above, the utility model provides a kind of rear top control arm of automobile, comprise bending Control arm body, be characterized in, Control arm body is the arm body being stamped to form by a block plate, this arm body has diapire and connects the two side of diapire, the free side of two side has flange so that the cross-sectional plane of this arm body is π shape, it is opening shape and two side folder type respect to one another structure that one end welded sleeve of Control arm body and the other end are diapire, the two side of this other end has mounting hole so that be connected with steering swivel, between the two side of this Control arm body, be also connected to brace panel.
Described rear top control arm of automobile, its further feature is that the middle part of this brace panel has lightening hole.
Aforementioned utility model is compared to left and right chip architecture form, its fusion length greatly reduces, also reduced weldquality, Control arm action can be reduced to the height of a weld seam simultaneously, expand design space, significantly improved Control arm rigidity property, two side flanging designs, use π type structural section, improved the rigidity property of Control arm.
Brief description of the drawings
The above and other feature of the present utility model, character and advantage are by by becoming more obvious below in conjunction with the description of drawings and Examples, wherein:
Fig. 1 is the block diagram of existing rear top control arm of automobile.
Fig. 2 is the block diagram of another kind of existing rear top control arm of automobile.
Fig. 3 is the block diagram of the rear top control arm of automobile of an embodiment of the utility model.
Fig. 4 is the block diagram that has shown the cross section of the rear top control arm of automobile of an embodiment of the utility model.
Fig. 5 is the upward view of the rear top control arm of automobile of an embodiment of the utility model.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail; set forth in the following description more details so that fully understand the utility model; but the utility model obviously can be implemented with the multiple alternate manner that is different from this description; those skilled in the art can do similar popularization, deduction according to practical situations without prejudice to the utility model intension in the situation that, therefore should be with the content constraints of this specific embodiment protection domain of the present utility model.
In Fig. 4, shown the shape of cross section of Control arm body by blocking a part of mode.It should be noted that these and follow-up other accompanying drawing are all only as example, it is not to draw according to the condition of equal proportion, and should be using this as the protection domain of the utility model actual requirement is construed as limiting.
As shown in Figure 3 to Figure 4, rear top control arm of automobile comprises bending Control arm body 1, Control arm body 1 is the arm body being stamped to form by a block plate, this arm body has diapire 11 and connects the two side 12 of diapire 11, 13, two side 12, 13 free side has flange 17 so that the cross-sectional plane of this arm body is π shape (having special demonstration in Fig. 4), it is opening shape 15 and two side folder type respect to one another structure that one end welded sleeve 14 of Control arm body 1 and the other end are diapire, there is mounting hole 16 so that be connected with steering swivel in the two side of left end, as shown in Figure 4 and Figure 5, the two side 12 of Control arm body 1, between 13, be also connected to brace panel 18.Brace panel 18 does not cover whole Control arm length, on it, microscler lightening hole 19 can be set.
Because Control arm body is that a slice steel plate punched forms, fusion length compared with left and right chip architecture form greatly reduces, reduce weldquality, Control arm action can be reduced to the height of a weld seam simultaneously, expand design space, significantly improved Control arm rigidity property, two side flanging designs, the use π type structural section of novelty, has improved the rigidity property of Control arm.
Although the utility model with preferred embodiment openly as above, it is not for limiting the utility model, and any those skilled in the art, not departing from spirit and scope of the present utility model, can make possible variation and amendment.Therefore, every content that does not depart from technical solutions of the utility model, any amendment, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, within all falling into the protection domain that the utility model claim defines.
Claims (2)
1. rear top control arm of automobile, comprise bending Control arm body, it is characterized in that, Control arm body is the arm body being stamped to form by a block plate, this arm body has diapire and connects the two side of diapire, the free side of two side has flange so that the cross-sectional plane of this arm body is π shape, it is opening shape and two side folder type respect to one another structure that one end welded sleeve of Control arm body and the other end are diapire, the two side of this other end has mounting hole so that be connected with steering swivel, is also connected to brace panel between the two side of this Control arm body.
