Description
The present invention relates to two-wheeled anterior suspended structure and steering hardware thereof.
Existing two-wheeled anterior suspended structure, for example the spy opens the shown in Figure 1 of 54 No. 77 patent gazettes of flat 8-17 " driving engine of two-wheeled grade and the switchover apparatus of motor ", generally adopts telescopic suspended structure.Having on sleeve-type suspended structure two-wheeled, suspension and steering arrangement is become one.
Though above-mentioned socket type suspended structure is widely adopted at present, its preceding pipe has born front-wheel from the whole load of ground-surface, and therefore, the car body body frame around the preceding pipe must have the rigidity of height.
But preceding pipe also is the parts of decision cornering properties, and hope can be adjusted (aim at wheel flutter and connecting rod) arbitrarily according to different car types, because every kind of car all is provided with the vehicle frame of high rigidity around preceding pipe, has just reduced its commonality.
For this reason, known technology is to adopt the rocking arm form that front-wheel can be swung up and down, the suspended structure that pipe and steering hardware separate before making.But, when handling front-wheel, must make front arm not interfere front-wheel.Therefore, front arm has big making a circulation from the car body framework to the side direction of front-wheel.The result causes front arm to protrude on the side significantly.Particularly, under the occasion that adopts large diameter wheel, it is more remarkable that this tendency becomes, thereby caused the deterioration of maximization, weight increase and the outward appearance of front arm.
In addition, because the restriction that front space is subjected to is more, be difficult to the configuration damper for shaking of rocking arm.Damper is configured in the car body center also to be not suitable for.
Also have, when front arm being shaken, absorb by connecting rod under the occasion of this up-and-down movement, dispose connecting rod between front-wheel and the preceding pipe at steering hardware when the front-wheel up-and-down movement, thereby need the space of connecting rod activity, therefore brought significant impact body frame and structure.
Since originally just be subjected to the influence of wheel, the restriction of between front-wheel and preceding pipe, having living space, and particularly, when adopting large diameter wheel, it is more remarkable that above-mentioned tendency becomes.
The inventor turns to purpose with the light weight of car body framework, and the suspended structure that replaces sleeve-type to hang is proceeded research, has improved suspended structure, by separating of steering hardware and suspension gear, has successfully adopted another kind of suspended structure.
Particularly, the present invention is a kind of the two-wheeled of following characteristics that have, that is: this kind is two-wheeled is equipped with a front arm that can swing up and down in the body frame front portion, the front-wheel that can freely rotate is installed on this front arm again, sees it is the rod member that approximately is the reverse U shape shape from the side of front arm.
The side is inverted U-shaped front arm and the neighboring of front-wheel intersects on the position that is higher than the front-wheel line of centers, when wheel steering, at the front-wheel amplitude at this crossover location place less than amplitude in the front-wheel outer peripheral edges at front-wheel center height place.Therefore, front arm is on the less position of front-wheel amplitude, and when when avoiding with front-wheel that interference is made a circulation, front arm is little to the overhang of vehicle-width direction.So just help the miniaturization and the lightweight of front arm, and relate to the minimizing of unsprung weight and the minimizing of amplitude direction moment; Can also improve and handle stability and beautify outward appearance.
Also have, the inventor proceeds research to the suspended structure that replaces sleeve-type to hang, and has improved suspended structure, by separating of steering hardware and suspension gear, has successfully adopted another kind of suspended structure.
Particularly, the present invention is have following characteristics a kind of two-wheeled, in its body frame front portion the front arm that can fluctuate is installed, between body frame and front arm, damper is installed, the front-wheel that can freely rotate is installed on this front arm, simultaneously, the top of the front portion of body frame have one upwardly extending before the pipe support tube, preceding pipe is fixed on the front end of pipe support tube before this, installing on preceding pipe can rotating handgrip again, preceding pipe support tube is put to a lateral deviation of car body line of centers, at the opposite side configuration of car body line of centers and the damper of preceding pipe support tube adjacency.
Because preceding pipe support tube is positioned at the offset position place of car body line of centers one side, thereby can try one's best near car body line of centers ground configuration damper.Therefore, reduced to act on the moment of deflection on the damper, and can reduce the requirement of strength of damper, can make the damper miniaturization, for the more anterior helicoid steering hardware of space constraint, be can good conformity mechanism.
In addition, the inventor is a purpose to overcome the problems referred to above, and the suspended structure that replaces the sleeve-type suspension is continued research, by the improvement to the necessary connecting rod mechanism of foresteerage gear, has successfully adopted another kind of suspended structure.
Particularly, by the front arm that can fluctuate front-wheel is assembled on the body frame, simultaneously, the direction by another root deflecting bar manipulation front-wheel beyond the front arm is characterized in that, makes deflecting bar be linked to the knuckle that front-wheel is used by connecting rod mechanism; Meanwhile, this connecting rod mechanism is configured among the wheel of front-wheel.
As long as deflecting bar is attached on the knuckle that front-wheel uses, just can form simple structure by connecting rod mechanism, owing to steering hardware and suspended structure are separated, for various pattern, high rigidity body frame that can general front arm hinge portion.

Below based on Figure 13, adopt inverted U-shaped reason to describe to front arm 42 sides.
Figure 13 (a)～(c) is the instruction diagram that shows the relation of front arm and front-wheel.
In Figure 13 (a), be exactly the front arm 42 that embodiments of the invention are adopted with the represented parts of solid line; Long and two-short dash line is represented the front arm Fa of illustration as a comparison.Because the side of front arm 42 approximately is inverted U-shaped, the neighboring of front arm 42 and front-wheel 3 intersects at the P near the front-wheel center O
1The position.In contrast to this, the front arm Fa of illustration is a horizontally extending rocking arm on the line of centers height of front-wheel 3 as a comparison, and the outer peripheral edges of this front arm Fa and front-wheel 3 intersect from front-wheel center P farthest
2The point position.
Figure 13 (C) is a planar view, and the relation of expression front arm Fa and front-wheel 3 is under the situation of θ at the deflection angle of front-wheel 3, and the slant distance of 3 outer rims is S from the car body center C to front-wheel
2The front arm Fa of this comparative example, for avoid with front-wheel 3 interferences for the purpose of, be necessary circuitous bigger slant distance S2.Therefore, front arm Fa is also bigger in the overhang of cross-car.
Figure 13 (b) also is a planar view, has represented the front arm 42 that adopts in an embodiment of the present invention and the relation of front-wheel 3.Because the outer peripheral edges of front arm 42 and front-wheel 3 intersect at location point P
1The place is under the situation of θ at the deflection angle of front-wheel 3, and the slant distance from the car body center C to the front-wheel outer rim is S
1, S
1Slant distance S less than above-mentioned comparative example
2Therefore, for avoid with front-wheel 3 interferences for the purpose of, the slant distance S that front arm only need make a circulation less
1Get final product, less in the overhang of vehicle-width direction.Because the overhang of front arm 42 is little, makes two-wheeled miniaturization.
That is to say, see that from the side the outer peripheral edges of the front arm 42 that approximately is inverted U-shaped and front-wheel 3 intersect at position (the some P that is higher than the front-wheel center O
1The position).On this crossover location, the amplitude when front-wheel 3 turns to is less than the amplitude of front-wheel 3 outer peripheral edges on front-wheel center O height.Therefore, front arm 42 can go around on the less position of front-wheel 3 amplitudes, and avoids the mutual interference with front-wheel 3.
Below, the effect of front-end equipment 4 is described according to Fig. 4 and Fig. 7.
The effect of the front damper 45 of Fig. 4 is to alleviate front arm 42 at the amplitude that shakes on the direction.
In addition, as seen from Figure 7, act on the impulsive force that shakes on the front arm 42 on the direction, pass from the back side of Rocker arm 42 to resin spring 44; The impulsive force that shakes direction at front arm for 42 times then passes to resin spring 44 by seizing plate 49 on both sides by the arms.At this time, resin spring 44 produces the action of the spring of elastic deformation, thereby relaxes impulsive force.
As mentioned above, front-end equipment 4 utilizes resin spring 44 to relax impulsive force, and the amplitude that relies on front damper 45 to reduce to vibrate.
As mentioned above, resin spring 44 plays action of the spring by the little stroke that has only elastic deformation, and can be adapted to the far-ranging loading from little loading to big loading.And compare with coil spring, resin spring is very small-sized.
Therefore, form the common suspension gear of one with coil spring and damper and compare, suspension gear of the present invention can keep little stroke in loading scope widely, be small-sized suspension gear, and be convenient to be disposed in narrow space.
