The specific embodiment
Although this paper diagram has also been described concrete embodiment, for a person skilled in the art, any device that can reach identical purpose can substitute the described specific embodiment.The application comprises any alternative scheme of the present invention or deformation program.Therefore, very clear, the present invention is only by claim and be equal to embodiment and limit.
When bumping, the impact of input acts on the vehicle frame 50 by bumper 53.For the distortion that reduces the vehicle interior driving compartment with the protection passenger, wish by make vehicle frame 50 in the front portion of vehicle fore-and-aft direction or the rear portion deformation takes place absorbs the impact intake effectively, rather than make inner driving compartment distortion.Absorbing the mode of texturing of impacting intake most effectively by vehicle frame 50 is, at axial direction generation compressive deformation.
But, for scheme drawing shown in Figure 4, publication number is the described prior art of unexamined Japanese patent application of 2002-160663, the attaching parts 52 of auxiliary connection vehicle frame 51 and vehicle frame 50 is fastened on the vehicle frame 50, and has predetermined length at above-below direction.Therefore, because collision, the application force of vehicle fore-and-aft direction is input to vehicle frame 50, the rigid central position G of connected structure that accept to impact the vehicle frame 50 of input and attaching parts 52 is at a G, some G the vehicle above-below direction than impact entrance point more by under, shown in the A-A cross-sectional plane of Fig. 4, so apply moment A at center-point G place, at the intermediate force square B of length direction, shown in Fig. 4 (b), vehicle frame 50 trends towards in out-of-plane direction distortion.When direction outside the plane was out of shape, vehicle frame 50 reduced in the shrinkage amount of compression direction (fore-and-aft direction of vehicle), and the energy that absorbs is less.
The present invention is conceived to the problems referred to above, its objective is to improve the vehicle frame place impacts input to the vehicle fore-and-aft direction energy absorption efficiency.
According to the present invention, even vehicle frame and subframe have at above-below direction under the situation of configuration of certain distance, because when the vehicle fore-and-aft direction bumped, the mode of texturing of vehicle frame mainly was the compressive deformation at the vehicle fore-and-aft direction, therefore can absorb impact energy effectively.
Following with reference to accompanying drawing, embodiments of the present invention are described in detail.
Present embodiment has illustrated the situation of the embodiment of F/F vehicle structure, and its driving engine is arranged on the front end of vehicle fore-and-aft direction.Fig. 1 is the diagrammatic side view of the engine support structure of present embodiment.
Below aforementioned vehicle frame 1, subframe 3 relatively is set, thereby leaves certain preset distance at above-below direction.
The following describes elastic support structure.
The front end of the front end of described front vehicle frame longeron 2 and main body of vehicle frame part 4 is connected by attaching parts 5, and described attaching parts 5 extends at above-below direction.The front end of the bottom of attaching parts 5 and main body of vehicle frame part 4 combines and forms one.
And then the top of attaching parts 5 is connected to the front end of front vehicle frame longeron 2 by aforesaid free body 6.As shown in Figure 2, aforementioned free body 6 comprises elastic body 6c, and it makes axle between the inner core 6a and urceolus 6b of above-below direction and arranged coaxial.Urceolus 6b is by the top that method is fixed on attaching parts 5 such as being pressed into, and inner core 6a is fixed on the aforesaid front vehicle frame longeron 2 by tie bolt 12, and this tie bolt passes the inside of inner core 6a.Urceolus 6b is shorter in length than inner core 6a, thereby has formed predetermined gap between the bottom of the upper end of urceolus 6b and front vehicle frame longeron 2.
In addition, free body 8 resilient mountings are passed through below the sloping portion 2a of front vehicle frame longeron 2 in the lower end of main body of vehicle frame part 4.
Driving engine 7 is loaded on the subframe 3 by installing component 13 then.
The following describes the work and the effect of present embodiment.
In the aforesaid engine support structure, attaching parts 5 is connected with subframe 3 and forms one, and therefore 5 and 3 rigidity is all big.In other words, 5 are connected like this with 3, make at least at axle to be that constrained force on the hand of rotation of vehicular transverse direction is very big.On the other hand, attaching parts 5 is connected on the front vehicle frame longeron 2 by elastic body 6c, this connection mode can make them shake mutually, in other words, connecting like this makes the rigidity of connecting bridge little, to guarantee at least at axle is that constrained force on the hand of rotation of vehicular transverse direction is less, and perhaps constrained force is similar to 0.Therefore, when importing load when the vehicle fore-and-aft direction affacts front vehicle frame longeron 2, almost the cross-section center with front vehicle frame longeron 2 is consistent for the rigid central position G of the connecting portion office of described front vehicle frame longeron 2 and attaching parts 5 (the A-A position of Fig. 1) vehicle above-below direction, in addition, also almost the cross-section center with front vehicle frame longeron 2 is consistent at the rigid central position G ' of the front vehicle frame longeron 2 of the pars intermedia office (the B-B position of Fig. 1) of front vehicle frame longeron 2 length directions vehicle above-below direction.
Therefore, when because the collision, when power acts on the front vehicle frame longeron 2 at the vehicle fore-and-aft direction, because aforesaid impact input and not having or very little in the moment that rigid central position G or G ' locate to produce, therefore, even between front vehicle frame longeron 2 and the subframe 3 segment distance is arranged, even perhaps they connect by attaching parts 5, in the time of also can reducing to impact owing to the antagonistic force of subframe 3 is applied to moment of deflection on the front vehicle frame longeron 2.As a result, in the input of vehicle fore-and-aft direction, the distortion of compression direction plays a major role during with respect to impact, shown in Fig. 1 (b), front vehicle frame longeron 2 does not deform in out-of-plane direction, and only is in compression direction generation shrinkage, thereby the energy that absorbs increases.
And then as mentioned above, along with front vehicle frame longeron 2 is compressed at the vehicle fore-and-aft direction, the top of attaching parts 5 tilts at the vehicle fore-and-aft direction, but owing to be fixed to the upper end of the urceolus 6b on the attaching parts 5 and predetermined gap is formed on the bottom of front vehicle frame longeron 2, can avoid the described constrained force of front vehicle frame longeron 2 and attaching parts 5 connecting portion offices to increase always, be in contact with one another up to upper end and the front vehicle frame longeron 2 of urceolus 6b.In addition, even having touched the constrained force of front vehicle frame longeron 2 and described hand of rotation, the upper end of urceolus 6b increases, this constrained force is still much smaller than the constrained force of attaching parts 5 and subframe 3 connecting portion offices, like this, the input moment of deflection that is input on the front vehicle frame longeron 2 at above-below direction is little, and the distortion of compression direction remains main.
In addition, on front vehicle frame longeron 2, the vibrations of the subframe 3 that driving engine 7 vibrations cause are not easy to be delivered on the front vehicle frame longeron 2 by free body 6 and 8 resilient mountings in the rear and front end of (driving engine 7 thereon) because subframe 3.In other words, the vibrations of the subframe 3 that increases when the vibrations of driving engine 7 are transmitted can be avoided being delivered to front vehicle frame longeron 2, and the performance of noise and vibrations has also been improved.
In addition, for aforesaid embodiment, elastic body 6c is inserted between 2 and 5, thereby they are connected in the mode that can shake mutually, as long as but the connecting bridge that can reduce attaching parts 5 and front vehicle frame longeron 2 is the constrained force on the hand of rotation of vehicular transverse direction at axle, the present invention is not limited to this connection mode.Therefore, for example, using axle to be the pin connection mode or the universal-joint connection mode of vehicular transverse direction, is that constrained force on the hand of rotation of horizontal direction can reduce or be set to 0 at axle at least.
Simultaneously, for aforesaid embodiment, although attaching parts 5 and subframe 3 are connected in one, as shown in Figure 3, attaching parts 5 also can be connected by elastic body 10 with subframe 3.In this case, the rigidity of the elastic body 10 of auxiliary connection vehicle frame 3 and attaching parts 5 is greater than the rigidity that places the elastic body 6c between front vehicle frame longeron 2 and the attaching parts 5.Therefore, above-mentioned effect can keep always, meanwhile makes the vibrations of subframe 3 be difficult to be delivered to front vehicle frame longeron 2.
In addition, for aforementioned embodiments, provided the present invention and be applied in embodiment in the F/F vehicle structure, but the present invention can also be applied in the rear engine vehicle structure, and when the collision that takes place from the vehicle rear direction, also can obtain same effect.
In addition, for aforesaid embodiment, having provided the present invention is applied in subframe and supports embodiment in the vehicle structure of driving engine, but the present invention is applied in subframe not to be supported in the vehicle structure of driving engine, also can obtain identical effect, support is positioned at the change-speed box or the suspension arm of the trailing wheel end of F/F vehicle as subframe, and perhaps subframe supports the change-speed box or the suspension arm of the front-wheel end that is positioned at rear engine vehicle.
About aforementioned prior art, publication number is that also there are the following problems for the unexamined Japanese patent application of 2003-246276.At first, bolt must long enough, with can fastening reliably set free body and escapement, makes them overlap each other on above-below direction, therefore must consider fastening insecure problem that may rupture and cause owing to bolt.In addition, in this structure, below subframe, place retainer and fall, like this to prevent subframe, because retainer takes up space, cause height off the ground to reduce, therefore, if too low,, just can not use retainer for fear of interfering with ground-surface apart from floor level.
In view of these problems, it is fixing unreliable to the objective of the invention is to prevent, a kind of suspension device for vehicle that can easily be applied on the various vehicles is provided.
In order to solve foregoing problems, the suspension device for vehicle among the present invention has a subframe, described subframe be positioned at chassis side rail below, wherein, chassis side rail and subframe are connected by the support component that extends at above-below direction; Described support component is provided with: cartridge, described cartridge are connected on the aforesaid subframe and extend upward; And the support elastic body, described support elastic body is inserted into the top of described cartridge, and its lower-upper length is shorter than described cartridge; Wherein, described support elastic body is fastened on the chassis side rail reliably by bolt, and described bolt passes the support elastic body at above-below direction.
According to the present invention, can shorten bolt, so just can avoid because unreliable the fixing that bolt fracture causes.In addition, the present invention is applicable to all types of vehicles.
Next, with reference to accompanying drawing embodiments of the present invention are described.
Figure 5 shows that the cross sectional drawing of the suspension device for vehicle structure that present embodiment relates to.
When vibrations when subframe 502 passes over, in the lining urceolus 533b vibrations that are shorter in length than lining inner core 533a of above-below direction, but these vibrations have been reduced by rubber components 533c, can pass to lining inner core 533a or chassis side rail 501 hardly.In addition, the upper end of lining urceolus 533b is outwardly-bent and the time pressed when assembling, touches the upper end of inner cylinder member 532 up to it.
In addition, the packing ring that is used for binding bolt 505 is corresponding with retainer of the present invention 504, and its external diameter than free body 533 bottoms is big, and is more smaller or identical than the external diameter of the foil portion 532b of inner cylinder member 532.Free body 533 and inner cylinder member 532 are positioned on the axle identical with retainer 504, like this, free body 533 and foil portion 532b all at above-below direction towards retainer 504.
The following describes the work effect of support component 503 with aforementioned structure.
At first, for above-mentioned structure, free body 533 is installed in the hollow parts of outer cylinder member 531, and with as existing escapement, described free body 533 is fastened on the chassis side rail 501 reliably by bolt 505.Therefore, bolt 505 can shorten, to reduce the unreliable fastening generation that causes owing to bolt fracture.
In addition, for said structure, the foil portion 532b of free body 533 and inner cylinder member 532 at above-below direction towards retainer 504.Therefore, damage along with the time is aging owing to rubber components 533c and fall with the chimeric inner cylinder member 532 of lining inner core 533b at free body 533 with the outside, and under inner cylinder member 532 situation about falling from free body 533, retainer 504 will support free body 533 and foil portion 532b, prevent that subframe 502 from falling.
In addition, for aforesaid structure, retainer 504 is included in the hollow parts of outer cylinder member 531.Therefore, even retainer has been installed, height off the ground can not hang down yet and make this structure and road surface interference, and above-mentioned structure can be used for various types of vehicles, and former this is impossible.
In addition, for aforesaid structure, compare with the telescoping part 532a of inner cylinder member 532, the outside dimension of foil portion 532b diminishes, and the external diameter of retainer 504 is identical with the external diameter of foil portion 532b.Therefore, by making the diameter of retainer 504 as much as possible little, the external diameter of bottom can be done forr a short time than the diameter of the path part 531a of outer cylinder member 531, therefore, easily with above-mentioned structure applications in various vehicles.Simultaneously, when bottom and path part 531a the external diameter difference big, and they are when tightly being pressed together, manufacture difficulty will strengthen, cost up, but structure as described above if the external diameter difference reduces, just can be eliminated this problem.
In addition, for said structure, by making the telescoping part 532a of inner cylinder member 532 be longer than length with the path part 531a of the chimeric outer cylinder member 531 of this telescoping part in the length of above-below direction, just can select the installation site arbitrarily, and support component 503 can be adjusted in the length of above-below direction at above-below direction.Therefore, identical support component 503 can be used for various types of vehicles, space difference between the chassis side rail 501 of these vehicles and the subframe 502.Perhaps, by adjusting the length of support component 503 simply, can easily change the attitude of vehicle.
Much less, the present invention is not limited to aforesaid structure.
For example can also use structure shown in Figure 6.The following describes the difference of this structure and structure shown in Figure 5.
For the structure of Fig. 6, among the structure of support component and Fig. 5 some is different a little.In Fig. 6, support component 507 is provided with cartridge 571 and free body 573, but cartridge is not the double-barrel structure that is made of inner cylinder member and outer cylinder member like that in the image pattern 5.Cartridge 571 has path part 571a in the top, and free body 573 is entrenched among this path part 571a.Free body 573 is provided with lining urceolus 573b, lining inner core 573a and rubber components 573c, their connection mode as shown in Figure 5, with the difference of Fig. 5 be that lining urceolus 573b and cartridge 571 are directly chimeric.Therefore, longer than the path part 571a of cartridge 571 with the part of the chimeric lining urceolus 573b of cartridge 571 in the length of above-below direction, thus can adjust the installation site of above-below direction.In addition, packing ring is as retainer 506, and is identical with Fig. 5 situation.Yet in this structure, because individual components is not set, so the outside dimension of retainer 506 is bigger than the internal diameter of path part 571a, it can support the path part 571a of cylindrical member like this.In the drawings, reference number 571b is a weld zone.
For the structure of Fig. 6, can reduce the length of bolt 505, therefore needn't worry unreliable fastening.In addition, owing to retainer 506 is arranged in the hollow parts of cartridge 571, so can not cause height off the ground too low because of retainer 506 is set.
In addition, although do not draw among the figure, the individual components that constitutes foil portion is not limited to inner cylinder member 532, as mentioned above, as long as the one end can be connected on the outer cylinder member 531, the other end can dangle with the inside of cartridge unit outward, thus get final product relative with retainer.Yet if use the structure with inner cylinder member 532, and described inner cylinder member 532 is all chimeric with free body 533 and outer cylinder member 531, needn't worry that individual components falls, even from profile, makes and also becomes simple and easy.In addition, the structure that also can use the length of support component 503 to change.
