The specific embodiment
Below, illustrate suspension arm of the present utility model by accompanying drawing.In addition, in the embodiment of the following stated, the situation that suspension arm of the present utility model is applied to underarm is described.
[embodiment]
As shown in Figure 1, at Vehicular body front, extend the front cross rail (car body member) 11 that is provided with hollow form to overall width direction.This front cross rail 11, by making to be disposed at, the upper plate 21 on top is relative on above-below direction with the lower plate 22 that is disposed at bottom forms.
Here, at the overall width direction both ends of front cross rail 11, arm member 12 is arranged at overall width direction outside, and outstanding upward.In addition, the upper end of arm member 12, is arranged at institute below the longeron 13 of overall width direction both sides and supports.
In addition, in front cross rail 11, the rear side at overall width direction both ends, is formed with installation portion 11a.And front cross rail 11, at 4 of the upper ends of installation portion 11a and arm member 12 point, is supported by longeron 31.
In addition, form the cardinal extremity of the underarm (suspension arm) 14 of suspension system, by rubber bush 15, direction is rocked and is supported by the overall width direction both ends of upper plate 21 and lower plate 22 up and down.And, on the top of underarm 14, by sphero-joint 16, support the steering swivel (omitting diagram) of wheel flutter (front-wheel) 17.Like this, by being installed on the front cross rail 11 supporting suspension systems of longeron 13, can improve the support stiffness of this suspension system.
In addition,, at upper plate 21 and above underarm 14, be supported with stabiliser 18.This stabiliser 18 is arranged in overall width direction above upper plate 21 and underarm 14.In addition, in underarm 14, the overall width direction both ends of stabiliser 18, are connected by rubber bush 19.Like this, by with front cross rail 11 and underarm 14 supporting & stablizing devices 18, can improve the roll rate of vehicle.
Below, illustrate the formation of underarm 14 by Fig. 2~Fig. 5.In addition, in Fig. 2~Fig. 5, illustrate the underarm 14 that is arranged at overall width direction left side.
As shown in Figure 2 to 4, underarm 14, the moulding by punch process panel beating material, it is the arm member of 1 block of plate of plan view shape triangular in shape.In addition,, in the time of punch process panel beating material, for the peripheral edge portion of underarm 14, implement flange processing downward.
, the peripheral edge portion of underarm 14, by being disposed at the inside flange portion 31 of overall width direction inner side, the rear flange portion 33 that is disposed at the forward flange portion 32 in car body front and is disposed at car body rear forms.
Inside flange portion 31, is arranged on car body fore-and-aft direction, and forward flange portion 32, is arranged in overall width direction.And, rear flange portion 33, along with from overall width side towards inner side (base end side) to overall width direction outside (tip side), extended one-tenth is bent into concavity towards car body front.
In addition,, in rear flange portion 33, be formed with curve 33a.This curve 33a, by by the lower end of rear flange portion 33 to its inside bend and moulding, in rear flange portion 33, it is formed at than the part of the more close car body anterior position in the rear end of wheel flutter 17.
More particularly, as shown in Figure 5, the deflection angle α of wheel flutter 17 is being made as under maximum state, in rear flange portion 33 part relative with the medial surface 17a of wheel flutter 17, is being formed with curve 33a.,, in the time that the deflection angle α of wheel flutter 17 is maximum, the medial surface 17a of wheel flutter 17 approaches curve 33a most.
In addition, in underarm 14, be formed with mounting hole 41,42, wheel is used supported hole 43 and supported hole 44 for stabiliser.
Mounting hole 41 is mounting holes that the cardinal extremity for making underarm 14 is supported in the car body front between upper plate 21 and base plate 22, and it is disposed at the cardinal extremity bight, front being formed by inside flange portion 31 and forward flange portion 32.On the other hand, mounting hole 42 is mounting holes that the cardinal extremity for making underarm 14 is supported in the car body rear between upper plate 21 and base plate 22, and it is disposed at the cardinal extremity bight, rear being formed by inside flange portion 31 and rear flange portion 33.,, in mounting hole 41,42, above-mentioned rubber bush 15 can be installed.
Wheel is the supported holes for supporting wheel flutter 17 with supported hole 43, and it is disposed at the bottom corner being formed by forward flange portion 32 and rear flange portion 33., with in supported hole 43, above-mentioned sphero-joint 16 can be installed at wheel.
Stabiliser supported hole 44 is the supported holes for supporting & stablizing device 18, and it is disposed at region relative with curve 33a on car body fore-and-aft direction.,, in stabiliser supported hole 44, above-mentioned rubber bush 19 can be installed.
Therefore, according to underarm 14 of the present utility model, form curve 33a by the lower end in rear flange portion 33, can make the medial surface 17a of the wheel flutter 17 being diverted relative with this curve 33a.Accordingly,, suppose when maximum at the deflection angle α of wheel flutter 17 that chain is installed, even if this chain touches rear flange portion 33, also owing to being formed with curve 33a, can suppress chain and be stuck.Therefore, can prevent the damage of underarm 14 and chain.
Supported hole 44 for stabiliser on boring in addition, as mentioned above, for improving the roll rate of vehicle, is necessary to make underarm 14 supporting & stablizing devices 18, if but may reduce the rigidity of underarm 14 and the support stiffness of stabiliser 18 in this underarm 14.Therefore, even in underarm 14, along the region of curve 33a, also can become the higher region of rigidity of underarm 14, therefore make stabiliser supported hole 44 be formed as approaching this curve 33a.Accordingly, can prevent that the rigidity of underarm 14 and the support stiffness of stabiliser 18 from reducing.
Utilizability in industry
The utility model, by realizing the higher stiffness of suspension arm, can be applicable to improve the body construction that wheel support stiffness is object.
