Curb girder 12.Draft hitch 20 is installed on vehicle 100, at mounted draft hitch, front-wheel 102 is installed.Carry out other installation
Operation, completes vehicle 100.
Additionally, installation portion 16 can overlap polylith reinforcing plate 52, by adjust reinforcing plate 52 block number is set, it is thus possible to
Enough adjust installation portion 16 to load relative to the disengaging of curb girder 12.
Thus, at vehicle 100, installation portion 16 utilizes reinforcing plate 52 to be set as the desired suspension crossbeam 10 departing from load,
Installation bolt 48 is utilized to be fixed on curb girder 12.
Then, effect, the effect of suspension crossbeam 10 is illustrated.Such as, with vehicle 100 from frontal collisions barrier
As a example by situation.In the case of collision is slow-footed, curb girder 12 grade of vehicle 100, the collision area deformation of vehicle 100, absorb
Crash energy.In the case of crash energy is little, the deformation of curb girder 12 is little, impacts suspension crossbeam 10 hardly.
On the other hand, in the case of collision is fireballing, the deformation of curb girder 12 increases, and suspension crossbeam 10 extrudes rear, right
Installation portion 16 applies power.
When suspension crossbeam 10 absorbs crash energy and rearward moves, installation portion 16 centered by installation is with bolt 48 backward
The mode that side, side rotates deforms.It is to say, the front of installation portion 16 becomes the state towards front side.And then, suspension is horizontal
When beam 10 rearward moves and continues deformation, the upper wall 37 of installation portion 16, lower wall 39 are because of installation bolt 48, and become relatively
To the state of vehicle front side stretching, crack at the upper bolt hole 42 of upper wall 37 and the lower bolt hole 44 of lower wall 39.It addition,
Reinforcing plate 52 is relatively stretched to vehicle front side by cylinder 56 simultaneously, such as, produces the crackle shown in dotted line H of Fig. 5 and sends out
Raw fracture.
When upper bolt hole 42, the crackle of lower bolt hole 44 amplify and reinforcing plate 52 ruptures, remain installation bolt 48 and cylinder
Body 56, installation portion 16 is extracted from installation bolt 48.Then, suspension crossbeam 10 departs from downwards from curb girder 12.Thus, electromotor
106, variator 108 falls, when colliding, it is possible to prevent electromotor 106, suspension crossbeam 10 etc. from invading the car indoor of vehicle 100
Side.
Suspension crossbeam 10 is provided with two pieces of reinforcing plates 52 at installation portion 16, and the disengaging load raising of installation portion 16 is equivalent to two
The intensity of block reinforcing plate 52.Therefore, compared with the situation of the suspension crossbeam 10 installing the situation being not provided with reinforcing plate 52, vehicle
100 only by bigger crash energy, and suspension crossbeam 10 just departs from from curb girder 12.So, suspension crossbeam 10 need not change outstanding
The main part 14 of frame crossbeam 10, it becomes possible to easily vary the disengaging load of installation portion 16.
Then, the concrete using method of suspension crossbeam 10 is illustrated.Such as, gasoline is had to send out with identical car type class
In case of the vehicle of motivation type and mixed type.The vehicle of mixed type is owing to being mounted with motor, battery, thus weight ratio gasoline
The vehicle weight of engine models.Then, even if collide barrier with identical speed, the vehicle of the mixed type that weight is big can touch
The crash energy hitting region generation becomes big.
It is to say, use identical suspension crossbeam 10 at the vehicle of gasoline engine type and the vehicle of mixed type
In the case of, compared with gasoline engine type, the suspension crossbeam 10 of mixed type departs from timing earlier.
Send out it is assumed here that the disengaging load of the suspension crossbeam 10 not using reinforcing plate 52 and being formed is set to be suitable for gasoline
The vehicle of motivation type, to relevant suspension crossbeam 10 is installed on gasoline engine type vehicle situation and will install
The situation of the vehicle that the overlapping suspension crossbeam 10 installing two pieces of reinforcing plates 52 in portion 16 is installed on mixed type compares.
Two pieces of reinforcing plates 52 set thickness, overlapping block number, so as to the weight gain phase of the vehicle with mixed type
The disengaging load answered, thus the suspension crossbeam 10 of the vehicle of mixed type is by the weight gain of the vehicle of mixed type, utilizes and strengthens
Plate 52 improves the disengaging load of installation portion 16.And, make mixed type with the velocity conditions identical with the vehicle of gasoline engine type
Vehicle crash in the case of, installation portion 16 is in roughly the same with the situation of the vehicle of gasoline engine type timing fracture, outstanding
Frame crossbeam 10 departs from from curb girder 12.
As previously discussed, the suspension crossbeam 10 of present embodiment is only arranged at installation portion 16 needs the reinforcing plate 52 of block number,
Just can be simply by the value that disengaging adjustment of load is regulation of installation portion 16.At main part 14 without change, because of without
Again to adjust the setting of other functional surfaces of the riding stability of suspension crossbeam 10, vibration etc. such that it is able to suppression exploitation work
Measure, the rising of cost.Reinforcing plate 52 can be manufactured by processing sheet material, it is thus possible to is manufactured inexpensively.Reinforcing plate 52 exists
Install before engaging upper half parts 30 and lower half parts 32, thus manufacturing without big change suspension crossbeam 10.
Do not change the intensity of main part 14, rigidity, thus the impact on other functions of riding stability, vibration etc. suppresses
For Min., it is not necessary to be provided with the adjusting again of change etc. of the intensity of the circumferential component of suspension crossbeam 10.Reinforcing plate 52 with
The mode embedding wedge-shaped part is installed in installation portion 16, thus can be reliably and to be installed on peace in the way of having the intensity of regulation
Dress portion 16.
In reinforcing plate 52, become arc-shaped, the angle of reinforcing plate 52 and installation as by the dihedral of the intersection of side
The front side wall 41 in portion 16, rear wall 43 do not contact, because of the concentration without producing the stress caused because of angular contact, installation portion 16
Intensity stabilization.Reinforcing plate 52 and cylinder 56 are almost without being fitted together to gap, and both do not fix, only when colliding, at suspension
The power that crossbeam 10 produces directly is passed on, to other to reinforcing plate 52, the place contacted with reinforcing plate 52 at cylinder 56 from cylinder 56
Function does not impacts, and can obtain stable intensity.
And, a part outside the overall width direction of reinforcing plate 52 is from being formed by the end of front side wall 41 and rear wall 43
Opening is prominent configuration outside installation portion 16, thus when colliding, the prominent part in reinforcing plate 52 cracks, reinforcing plate 52
Become to be easily broken off.Then, suspension crossbeam 10 easily departs from downwards from curb girder 12, it is possible to prevent suspension crossbeam 10 from swarming into vehicle
The car indoor of 100.
Suspension crossbeam 10 judges the intensity of the upper bolt hole 42 of upper half parts 30 and the lower bolt hole of lower half parts 32 respectively
The intensity of 44, it addition, reinforcing plate 52 easily calculates intensity in the case of easy shape, it is thus possible to set installation exactly
The intensity in portion 16.Reinforcing plate 52 prepares the different plate of thickness in advance, by selecting the reinforcement with the thickness of regulation from which
Plate 52 and be installed on installation portion 16 or change reinforcing plate 52 mounting blocks number such that it is able to be set as desired intensity.
Additionally, installation portion 16 is more than by tensile force, the power that also accept to turn, rotates and depart from from installation bolt 48,
Thus though the intensity of the installation portion 16 of suspension crossbeam 10 also has and makes the installation portion 16 being not provided with reinforcing plate 52 right the most simply
The installation intensity of bolt 48 and the reinforcing plate 52 situation to the numerical value of the intensity addition of cylinder 56, but this can suitably repair
Just.
As described above, according to the present invention, by arranging reinforcing plate 52 at installation portion 16, it is possible to easy and simple
