Abstract
The utility model discloses a back wheel shock absorbing structure of a swing-advancing vehicle, which is the combination of the connection of a back fork structure and a fixed structure formed by the changed back fork fixed originally below the left and right pedals. The fixed structure is arranged blow the pedal and provided with a top concave space for connecting with the front end of a back fork structure. The back end of the lower fork structure is provided with an axle fixation port for the back wheels to be installed by. The left-right lower fork structure swinging up and down below the left and right pedals causes the left and right back wheels to move up and down due to the uneven road surface on one hand and compresses the lower fork structure shoe and the elastormer between the pedal tubes to absorb the external force of shocking, therefore achieving the shock absorbing to the left and right back wheels.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Extremely shown in Figure 5 as Fig. 2, a kind of rear wheel shock-absorbing structure that waves the car that advances of improvement, mainly form by fixed seat structure 20, back fork structure 30, bearing 40, sleeve pipe 45, rotating shaft bolt 24, elastic element 44 and screw 26, fixed seat structure 20 is fixedly arranged on the bottom of left and right pedal (17A, 17B), and offers the concave shaped space 21 on the fore-and-aft direction downwards; Back fork structure 30 front ends are inserted in the concave shaped space 21 of fixed seat structure 20, and are articulated with permanent seat 20 by rotating shaft bolt 24 and screw 26, and the rear end is provided with aft-opening open space 38; The place ahead of open space 38 flexibly connects bearing 40, and the rear is to insert and fixing trailing wheel (15A, 15B); The bottom of left and right pedal (17A, 17B) is installed with sleeve pipe 45; Bearing 40 and the sleeve pipe 45 middle elastic elements 44 that are provided with.
The described rear wheel shock-absorbing structure that waves the car that advances, it is characterized in that: the both sides of fixed seat structure 20 are to being equipped with outer hole 22 and the curved slotted eye 23 of changeing, change hole 31 and preceding perforation 32 in back fork structure 30 front end correspondences are provided with, change hole 22 and interior commentaries on classics hole 31, curved slotted eye 23 and preceding perforation 32 outward all with rotating shaft bolt 24 and screw 26 location.
The described rear wheel shock-absorbing structure that waves the car that advances, it is characterized in that: back fork structure 30 middle parts suitably are provided with back perforation 33 apart from both sides, bearing 40 lower end correspondences are provided with circular hole 41, flexibly connect with rotating shaft 35 and with back fork structure 30, rotating shaft 35 middle parts are provided with internal screw thread 36, upwards screw in for trimming screw 34.
The described rear wheel shock-absorbing structure that waves the car that advances, it is characterized in that: bearing 40 is provided with concentric shrinkage pool 42 to insert the termination of elastic medium 44 with sleeve pipe 45,44 of bearing 40 and elastic mediums are provided with disk 43, prop up when upwards screwing in for trimming screw 34 with extruding elastic medium 44.
The described rear wheel shock-absorbing structure that waves the car that advances is characterized in that: curved slotted eye 23 ovalizes on the fixed seat structure 20, and with the amplitude of fluctuation of spacing back fork structure 30.
The described rear wheel shock-absorbing structure that waves the car that advances is characterized in that: the rear end of back fork structure 30 is provided with wheel shaft fixing port 37, captives joint with rear axle.
The described rear wheel shock-absorbing structure that waves the car that advances is characterized in that: described elastic medium 44 is spring or excellent power glue.
As Fig. 2, Fig. 4 and shown in Figure 5, suitably screw trimming screw (34) under curved slotted eye (23) limited field, make elastic element (44) reach certain precompressed amount, this moment is when waving the trailing wheel that advances (15) when produced by the concavo-convex external force in ground to shake, move on the trailing wheel and make back fork structure (30) clockwise direction rotation, drive bearing (40) thus on move and dwindle and pedal (17A, 17B) distance between the back side (46), therefore compress elastic element therebetween (40), and carried out following situation simultaneously:
One, the left and right wheel (15A, shock-damping structure 15B) (2) though belong to same patent structure, because of left and right the wheel (15A, 15B) respectively separately installing use, so its effect is separately independently, (15A, 15B) road conditions are different separately with left and right the wheel in the damping action.
Two, be subjected to curved slotted eye (23) the limited field effect of fixed seat structure (20), can limit upwards rotation angle of back fork structure (30), therefore can prevent that trailing wheel (15) is because of the excessive trailing wheel (15A that causes of elastic element (44) compression, 15B) touch left and right pedal (17A, 17B), cause danger.
Three, elastic element (44) also produces slightly flexural deformation with compression, under the small situation of deflection, when waiting to shake the external force disappearance, can reply original shape.
Since adopted said structure, the utility model can reach under complex road condition can safety and shock-absorption effect.
