Abstract
The utility model discloses a front wheel shock absorbing structure of a swing-advancing vehicle, which is formed like that based on the front fork structure of the front wheels back travel distance of the general swing-advancing vehicle, a rotation holes at the lower ends of a left-right upper fork structure is connected to the rotation shaft at the front end of a left-right lower fork structure, the front wheels are installed at a fixation port at the back end of the left-right lower fork. The front wheels are shocked in advancing due to the uneven road surface, and then the left-right lower forks structure swings upward to properly compress an elastic medium between a lower shoe of the left-right lower fork structure and an upper shoe of the left-right upper fork structure; when the external force disappears, the left-right lower fork structure turns downward back to stop when the retaining plate of the structure propping up the left-right upper fork structure; then the left-right upper fork structure and lower fork structure swing a little relatively and compress the elastic medium between, thereby achieving the shock absorbing to the front wheels.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown in Fig. 2 to 5, a kind of front-wheel shock-damping structure that waves the car that advances of improvement, mainly form by a pair of symmetrical last fork structure (21A, 21B), a pair of symmetrical lower fork structure (31A, 31B), last bearing 22, lower seat 35, elastic medium 40 and screw 38, about go up fork structure (21A, 21B) and place front-wheel 13 both sides, the upper end captive joint vertical tube of front fork 20 that curves inwardly, the lower end is respectively equipped with changes hole 27, for combining with left and right sides lower fork structure (31A, 31B) front end rotating shaft 32; About go up fork structure (21A, 21B) middle part suitably distance be installed with bearing 22 respectively, left and right sides lower fork structure (31A, 31B) middle part is provided with elastic medium 40 suitably apart from being installed with lower seat 35 respectively between last bearing 22 and the lower seat 35; Last bearing 22, elastic medium 40 run through locking with lower seat 35 by a screw 38.
Described left and right sides lower fork structure (31A, 31B) middle part is respectively equipped with the crooked catch 34 that stretches out, and goes up fork structure (21A, 21B) about reclining respectively.
Rear end, described left and right sides lower fork structure (31A, 31B) is respectively equipped with wheel shaft fixing port 37, is articulated with the front-wheel wheel shaft.
Well locate in order to give elastic medium 40, the described bearing 22 that goes up is equipped with concentric shrinkage pool (25,36) with lower seat 35, to insert the termination of elastic medium 40, run through locking with screw 38 again, also be provided with pad 26 between elastic medium 40 and last bearing 22, the lower seat 35.
The described bearing 22 that goes up is equipped with concentric projection with lower seat 35, to insert the termination endoporus of elastic medium 40, runs through locking with screw 38 again.
Shown in Fig. 2,3,5, suitably screwing bearing (22) trimming screw (23) to the desirable precompressed situation of left and right elastic medium (40) arrival, this moment is when being subjected to the concavo-convex external force in ground to produce vibrations when front-wheel (13), move on the front-wheel (13) and cause left and right lower fork structure (31A, 31B) the clockwise direction rotation drive move on the lower seat (35) and dwindle and last bearing (22) between distance, therefore compress elastic medium therebetween (40), and carried out following situation simultaneously:
One, two side-lens (34) with left and right lower fork structure (31A, 31B) rotation, leave left and right go up the fork structure (21A, structure 21B), after waiting to shake external force and disappearing, homing.
Two, two elastic mediums (40) also produce slightly flexural deformation, with the compresses in length effect, under the small situation of deflection, after waiting to shake external force and disappearing, can reply original shape.
When three, damping was stressed, (31A 31B) went clockwise direction rotation action to left and right lower fork structure, moves after moving slightly on the front-wheel (13), the utility model is applied to wave the advance patent characteristic scope of car that Here it is.
Owing to taked said structure, the utility model can be issued to desirable damping effect by complex road condition.
