Description
The present invention relates to a kind of suspension arm, it is used for the Jackstay type front suspension or the allied equipment of automobile.
Though use the suspension arm that forges usually, people also know the suspension arm that uses metal sheet to make for expendable weight.
In the suspension arm that this metal sheet is made, use the arm main body to form the box-shaped cross-sectional plane, thereby guarantee rigidity with the strenthening member that is connected thereon.Strenthening member generally is that the monomer that resembles the arm main body by drawing constitutes.
In above-mentioned common example, the size of strenthening member becomes bigger.Therefore, difficultly in dribbling, carry out the blank configuration (or blank configuration) that the arm main body is reinforced object, thereby feed stock cost is higher with high stock utilization (or high output capacity).
In this case, in order to improve the blank degree of utilization, can consider in the dribbling that separates, to carry out the blank configuration of arm main body and strenthening member.But, in this scheme,, need drawing equipment separately for stamping arm main body and reinforcing formation, thus can't cost-cutting.
In view of above-mentioned defective of the prior art, the purpose of this invention is to provide a kind of suspension arm cheaply.
To achieve these goals, metal suspension arm of the present invention comprises: an arm main body; With a strenthening member that is connected in the arm main body with formation box-shaped cross-sectional plane; Wherein, described strenthening member is divided into a plurality of solids that add; Described a plurality of strenthening member is connected to described arm main body by welding.
According to above-mentioned layout, each reinforcing member can reduce size, thereby in the configuration of its blank, can be with better blank degree of utilization, a plurality of reinforcing members are dispersed in the dribbling remaining space between the arm main body blank configuration section.Therefore, might be by reducing the cost that feed stock cost reduces suspension arm.
In order further to reduce the cost of suspension arm, preferably adopt the low what is called of machinework cost to drag the part pressing (cut and carry method of pressing) of advancing.But advance in the pressing at this part that drags, product must not gone out until product from dribbling and strike out net shape.Therefore, in drawing, because influencing each other between arm main body base grain configuration section and the reinforcing member blank configuration section (or effect) might make forming accuracy become bad.In this case, the arm main body forms C shape cross-sectional plane, and reinforcing member roughly forms plate shaped, and so, it is easy that the shaping of reinforcing member just becomes.Like this, the blank configuration section of the blank configuration section of arm main body and reinforcing member just is difficult for producing influencing each other.Therefore, even in order to improve the blank degree of utilization, the gap between the blank configuration section of arm main body and the blank configuration section of reinforcing member is less, and arm main body and reinforcing member also can drag the part drawing in the pressing of advancing with higher precision.Therefore might further reduce the cost of suspension arm.
In the Jackstay type front suspension, vertical (upper and lower) load is used for accepting (or supporting) bumper, and vertically (forward and backward) load is admitted by suspension arm.Therefore, suspension arm is made L shaped in planar view.At an end of suspension arm, be provided with connecting bridge (being also referred to as wheel side connecting bridge) in wheel side.The other end and sweep at suspension arm are respectively equipped with a connecting bridge in body side (being also referred to as the body side connecting bridge).In the state that part between the sweep and the described other end is arranged in the vertical, be bearing on the vehicle body swingably at sweep and the body side connecting bridge on the described other end, have in the vertical therebetween at interval, thereby guaranteed support stiffness in the vertical.When this suspension arm is to be made of the arm that a kind of metal sheet is made, and this arm comprises an arm main body roughly L-shaped in planar view and is connected on the arm main body when forming the strenthening member of box-shaped cross-sectional plane, strenthening member can be divided at least two and add solid, and they stretch to every end of arm main body from the sweep of arm main body.Therefore the same with above-mentioned example, can reduce feed stock cost, thereby reduce the cost of suspension arm.
The flexure stress that acts on the L shaped suspension arm becomes maximum at the sweep of suspension arm, does not act on very big flexure stress on every end of suspension arm.Therefore, even the part of the every end of close arm main body of each reinforcing member is made the tapered shape of width less than the arm body width, also no problem in view of intensity, by reinforcing member being made tapered shape, the remainder that stays between the blank configuration section of arm main body is implemented the configuration of reinforcing member blank more efficiently, thereby further improved the degree of utilization of blank, further reduced cost.

Fig. 3 is the planar view that is illustrated in the blank configuration of arm main body and reinforcing member in the first embodiment of the invention;
Fig. 4 is the planar view of expression second embodiment of the invention;
Fig. 5 is the planar view that is illustrated in the blank configuration of arm main body and reinforcing member in the second embodiment of the invention;
Fig. 6 is the planar view of expression third embodiment of the invention.
Fig. 1 is illustrated in the suspension arm that uses in the automobile Jackstay type front suspension.It is to be made of an arm main body roughly L-shaped in planar view 1 and a reinforcement feature that is connected in arm main body 1.Reinforcement feature is divided near the reinforcing member 2 that stretches to arm main body 1 one ends the curve of arm main body 1 and stretches to the reinforcing member 3 of the other end of arm main body 1 from curve.
Described end in arm main body 1 has one to engage mounting hole 1a, and it is a wheel side connecting portion, a ball-joint is housed so that be connected in the lower end of Hooke's coupling in it, thus the rotatably support wheel.In addition, at the curve of arm main body 1 the sleeve 1b of band rubber is housed, it is as the connecting portion of body side, and is rotatably supported on the vehicle body by a bolt (not shown).In addition, at the described opposite side of arm main body 1 a pin 1C is housed, it is as the body side connecting portion, and is rotatably supported on the vehicle body by a sleeve (not shown).Therefore, suspension arm is installed on the vehicle body swingably, and sleeve 1b and pin 1c aim on same straight line that extends in the vertical.
As Fig. 2 (A), shown in 2 (B) and 2 (C), arm main body 1 forms C shape roughly on cross-sectional plane.On the other hand, each reinforcing member 2,3 forms roughly plate shaped.By arc-welding or similar approach each reinforcing member 2,3 is connected on the arm main body 1, thereby forms the box-shaped cross-sectional plane.
The triangle that reinforcing member 2 forms roughly, described end towards arm main body 1 is tapered, thereby the inner side edge 2a of reinforcing member 2 on arm main body 1 crooked inside be provided with along the internal diameter edge of arm main body 1, and the outer side edges 2b on curved outer is with respect to the external diameter edge tilt of arm main body 1.Then inner side edge 2a is connected in the internal diameter edge of arm main body 1, outer side edges 2b is connected in a Width center projections 1d of portion who on arm main body 1, forms.In the present embodiment, in the part near the described end of suspension arm, its bending stiffness reduces.But consider and no problem that from the intensity direction this is because the flexure stress that acts on the described end of suspension arm is not very big.
Being arranged so that of reinforcing member 3, the inner side edge 3a of the reinforcing member 3 on the sweep of arm main body 1 places along the internal diameter edge of arm main body 1, the outer side edges 3b on the outside of sweep from sweep to sweep and the midway location between arm main body 1 other end be provided with along the external diameter edge of arm main body 1.Between the other end of midway location and arm main body 1, outer side edges 3b inwardly is offset from the external diameter edge of arm main body 1, thereby the part of the close described other end of reinforcing member 3 attenuates and forms the shape of width less than arm main body 1 width.Then, inner side edge 3a is connected in the internal diameter edge of arm main body 1, outer side edges 3b is connected in the external diameter edge of arm main body 1 at sweep, and the pin 1c that is connected at the described other end.In this embodiment, bending stiffness reduces in the part of the described other end of close suspension arm.But in view of intensity and no problem, this is that on the other hand, this is because the sweep of macrobending stress is reinforced by reinforcing member 3 in whole zone because be not very big at the flexure stress of the described other end of suspension arm.
Need not to consider the intensity of mount pin 1c as reinforcing, so, reinforcing member 3 can form the subtriangular shape shown in the imaginary line among Fig. 1, and this makes outer side edges 3b form departing from from the external diameter edge of arm main body 1 near a position of sweep.
The blank configuration (or blank configuration) of arm main body 1 and reinforcing member 2,3 is to make in a shared dribbling 10, as shown in Figure 3.They are simultaneously by dragging part continuity method (the cutand carry method) drawing of advancing.In this punching formation, be that the embodiment that constitutes of the single-piece by large-sized plate is different with reinforcing member, the remaining space that the blank configuration of two reinforcing members 2,3 stays after can utilizing the blank configuration of arm main body 1 to finish well.In addition, because reinforcing member 2,3 is formed approximate writing board shape, thereby make the shaping of reinforcing member 2,3 become easy.Even the gap between gap between the reinforcing member 2,3 and reinforcing member 2,3 and the arm main body 1 is stayed lessly, they do not bear the reciprocal influence that causes because of punching press yet, as the stretching of material, thereby each arm main body 1 can be with higher precision drawing with relevant reinforcing member 2,3.Therefore, logical using up may reduce feed stock cost greatly, can reduce the cost of suspension arm.
In the illustrated embodiment, for two right sides and left suspension arm, blank configuration makes and make arm main body 1 and relevant reinforcing member 2,3 in the dribbling 10 that can use jointly in two right sides and left side symmetry is organized.
In the drawings, the knock hole of label 11 representative location usefulness when the cutting of dribbling 10 and carrying.Knock hole 11 is formation in the blank configuration of configuration of the blank of arm main body 1 and relevant reinforcing member 2,3 respectively.Therefore, knock hole 11 can also be used for the location when arm main body 1 is interconnected with relevant reinforcing member 2,3.
In above-mentioned first embodiment, the footing that is used to reinforce the sweep of arm main body 1 is that (being reinforcing member 3) in reinforcing member 2,3 gone up and formed.But as shown in Figure 4, reinforcing member can be divided to form footing at the middle body of sweep on reinforcing member 2,3 in the mode of dividing.According to this layout,, thereby further improve the degree of utilization of blank even the gap between the blank configuration section of arm main body 1, still might be carried out the configuration of relevant reinforcing 2,3 blanks as shown in Figure 5 less than the foregoing description in those gaps.In the present embodiment, the shape of cross section of each part (or part) of suspension arm is with identical shown in Fig. 2 (A), 2 (B) and 2 (C).
In the embodiment shown in Fig. 1 and 4, reinforcing member is divided into two reinforcing members 2,3.But the number of cutting apart is not limited to 2.In other words, as shown in Figure 6, reinforcing member can be divided into three, comprises the reinforcing member 4 that is connected in arm main body 1 sweep, is connected in the reinforcing member 5 of arm and is connected in the reinforcing member 6 of arm at the described other end of arm main body 1 at arm main body 1 a described end.But,, will go to connect them by spended time so if reinforcing member is divided into 4 or more.Therefore, the number of reinforcing member is preferably 2 to 3.
The Jackstay type front suspension arm has been described above.But the present invention also can be used for the suspension arm of other type.
