The specific embodiment
Referring to figs. 1 through 3, will be described power assembly mounting structure according to the present invention hereinafter.Fig. 1 Figure 2 shows that the front elevation of this power assembly mounting structure for schematically showing the planar view of power assembly mounting structure, and Fig. 3 (a) is to the scheme drawing of the state of 3 (c) when being used to illustrate that load is input to crossbeam.
As shown in Figure 1, a pair of curb girder 1 and 1 longitudinal extension along vehicle, and crossbeam 2 is along the horizontally set of vehicle, and the two ends of this crossbeam are fixed on aforesaid curb girder 1 and 1.In addition, the dynamic assembly of being made up of driving engine 3 and change-speed box 45 is between right side beam 1 and left side beam 1 and be positioned at the rear of crossbeam 2.In addition, antihunting bar (bar) 6 is arranged between crossbeam 2 and the dynamic assembly 5, thereby sets up connection between dynamic assembly 5 and crossbeam 2.
In this structure, as shown in Figure 2, in front view, this all is parts in curb girder 1 and 1 each, and this parts cross section is for roughly U-shaped and upwards open (having opening at its top).This limits the both sides of vehicle body to curb girder 1 and 1.
In addition, hole 7 and 7 are made in two ends at crossbeam 2, and bolt (weld bolt) 9 and 9 is welded on curb girder 1 and 1 and hole 7 and 7 cooresponding positions, so that nut 8 and 8 is meshed with bolt 9 and 9 in patchhole 7 and 7, thereby crossbeam 2 is fixed on curb girder 1 and 1.
In addition, bar permanent seat 10 is used for the fixing antihunting bar 6 of the rotating mode of bar, and is outstanding downwards thereby this bar permanent seat is arranged on the lower surface of crossbeam 2.
As shown in Figure 1, one end 6a of antihunting bar 6 passes through elastic component, the lining of making as rubber is connected on the bar permanent seat 10 of crossbeam 2, thereby antihunting bar 6 can rotate, and its other end 6b is connected, is fixed on the dynamic assembly 5 by antihunting shaft bar 11 (on the dynamic assembly 5 with bar 6 bonded assembly point of connection), so that it can rotate.In addition, although do not illustrate, engine installation frame and erection of transmission frame (they will be called " dynamic assembly erecting frame " hereinafter together) resilient mounting are all passed through in the both sides of dynamic assembly.
And in planar view as shown in Figure 1, crossbeam 2 forms towards dynamic assembly 5 (just, in the present embodiment, rear portion towards vehicle) convex structure (being convex curvature) towards this dynamic assembly, and in the front elevation of Fig. 2, crossbeam is convex curvature up.Crossbeam 2 forms towards the convex structure reason of rear view of vehicle as follows:
Usually, along with driver's bend the throttle (just consistent with the increase of engine speed), driving engine (or dynamic assembly) can wave (swing) on predetermined direction.In this case, the center of the oscillating motion of driving engine (dynamic assembly) is not only according to engine characteristics and size, data such as weight and changing, and according to the position of dynamic assembly erecting frame, factor such as spring constant and changing.Therefore, though by adjusting engine design, the characteristic of dynamic assembly erecting frame etc. can make oscillating quantity minimize, but very do not paying attention to minimizing of oscillating quantity in being provided with of driving engine or dynamic assembly fabricated section, this is because will preferentially satisfy output characteristic, the requirement of shock absorbing characteristics and other characteristic.And, even parts are set, also be difficult to prevent fully the swing of driving engine in practice so that oscillating quantity minimizes.
Therefore, in the present embodiment,, crossbeam 2 and dynamic assembly 5 are interconnected by using antihunting bar 6 in order to suppress the swing of driving engine above-mentioned.This can help to suppress the swing of (restriction) driving engine 3.
Yet, in this structure, taking place at driving engine under the situation of swing, the corresponding compressive load of moment or the tension load that are produced with engine wobble act on the antihunting bar 6.
In this embodiment, adopt weave mode so that when engine speed improves, therefore the position that is fixed on the antihunting shaft bar 11 on the dynamic assembly 5 moves forward, and when hunting motion takes place, compressive load (referring to arrow A among Fig. 1) acts on the antihunting bar 6.
In this case, " weave mode " expression one specific character (swing characteristic), dynamic assembly 5 demonstrates this characteristic when swing, thereby can respond from the increase of the moment of torsion of dynamic assembly 5 outputs, the point of connection (being antihunting shaft bar 11) that makes the dynamic assembly 5 that has antihunting bar 6 is to crossbeam 2 side shiftings (being shifted).
Hereinafter with reference to Fig. 3 (a) to 3 (c), difference between two kinds of moments is described, a kind of moment is the moment that produces in this linear pattern crossbeam when load W is input on the general linear pattern crossbeam 102, and another kind of moment is the moment that produces in this convex crossbeam on load W is applied to according to the convex crossbeam 2 of present embodiment the time.
At first, shown in Fig. 3 (a) and Fig. 3 (c), when concentrated load W is input on the common linear pattern crossbeam 102, moment M
1Act on the common crossbeam 102 this moment M
1Be maxim at the concentrated load W place of applying.On the other hand, shown in Fig. 3 (b) and 3 (c), in the time of on concentrated load W (with consistent by the load of antihunting bar 6 inputs) affacts according to the convex crossbeam 2 of present embodiment, moment M
2Act on thereon this moment M
2Show maxim at the concentrated load W place of applying, and in this case, moment M
2Maxim M
2maxTorque gradient M

This is because from strong point R
2And R
2(corresponding to the point of connection of crossbeam 2 with curb girder 1 and 1) locates to have applied strong point antagonistic force F and F, and this antagonistic force supports convex crossbeam 2 towards the middle part of crossbeam 2, has produced counteracting moment M thus
3
Just, the structure that forms the convex curvature relative with load W input direction when crossbeam 2 (swells along the direction opposite with the load input direction, perhaps be convex curvature with close dynamic assembly 5) time, point of connection place in crossbeam 2 and curb girder 1 and 1 produces strong point antagonistic force, thereby can reduce to be applied to the moment of crossbeam 2.This is suitable to strengthen the situation of resisting the rigidity that is input to the load on the crossbeam 2 at crossbeam 2 with the counteracting moment loading.
In other words, when be input to load on the bar 6 from dynamic assembly 5 be compressive load shown in Figure 1, shown in the planar view among Fig. 1, crossbeam 2 formed towards dynamic assembly 5 convex curvature, can significantly strengthen rigidity like this.
Crossbeam 2 formation that Here it is are towards the convex structural reason of rear view of vehicle bending.
In this embodiment, bar permanent seat 10 is arranged on the crossbeam 2, can be with respect to crossbeam 2 centers along lateral direction of car a little to the state of vehicle right side displacement (skew), similarly, the connection between dynamic assembly 5 and the antihunting bar 6 is a little to the be shifted state of (skew) of vehicle right side.Manufacture is to consider that the swing characteristic of dynamic assembly 5 and the center of gravity of driving engine transversely are offset at it with respect to vehicle center to the right like this.Therefore, it is suitable that point of connection (position of shaft bar 11 just, is set) between point of connection between crossbeam 2 and the antihunting bar 6 (position of bar permanent seat 10 just is set) and antihunting bar 6 and the dynamic assembly 5 suitably changes according to dynamic assembly 5 swing characteristics or its center-of-gravity position.
Since according to the body structure of present embodiment according to top described being configured, so can obtain following effect.
At first, in planar view shown in Figure 1, although when because the compressive load that hunting motion produced of dynamic assembly 5 has moment to act on the crossbeam 2 when the axis direction of antihunting bar 6 acts on the crossbeam 2, but because the convex curvature (shown in Fig. 3 (b) and 3 (c)) that crossbeam 2 forms facing to the input load direction, at a R
2And R
2(just, curb girder 1 and 1 and two ends crossbeam 2 are corresponding parts respectively) locate to produce strong point antagonistic force F and F, thereby this antagonistic force supporting traverse 2 act on crossbeam 2 counteracting moment M is arranged
3Therefore, crossbeam 2 forms the convex structure opposite with load direction and can provide apparently higher than the rigidity of linear pattern crossbeam, thereby can support the dynamic assembly that is installed on the vehicle reliably.
In addition, because the axis direction effect at antihunting bar 6 upper edge antihunting bars 6 has compressive load, and in planar view, the convex structure that crossbeam 2 forms towards dynamic assembly 5 bendings is so thereby crossbeam 2 can show enough rigidity can be born from the load of dynamic assembly 5 inputs.
Moreover, in front view,, so for instance, when promptly box lunch makes bar permanent seat 10 grades be positioned at crossbeam 2 belows, also can guarantee the terrain clearance of vehicle as present embodiment because crossbeam 2 upwards is convex curvature.
Be appreciated that the present invention is not restricted to the described embodiments, all any modification, variations of being done within the spirit and principles in the present invention all should be included within protection scope of the present invention.
For example, though in the above-described embodiments, crossbeam 2 forms in planar view and is convex curvature towards dynamic assembly 5, in front view, upwards be convex curvature, but this is in order to imitate the weave mode of the driving engine (or dynamic assembly 5) in the present embodiment, if the engine wobble pattern is different with situation in the present embodiment, forming crossbeam at this weave mode so also is acceptable.
Just, crossbeam 2 can form the relative convex curvature that is of load direction with the swing that comes from driving engine at least.
