Description
Technical field
The utility model relates to the preceding damping of a kind of Electrical Bicycle, belongs to the Electrical Bicycle technical field.
Background technology
Two front shock absorbers of the preceding damping of existing bicycle standpipe bottom by preceding standpipe with before being fixed on constitute, and the bottom of two front shock absorbers is provided with the front axle mount pad, is installed on the front axle mount pad with front-wheel bonded assembly front axle.When riding, front-wheel absorbs and the ground-surface of decaying jolts through front shock absorber, to improve bicyclist's traveling comfort.But not enough is, parallel axes because of the axis and two front shock absorbers of preceding standpipe, after vehicle is subjected to ground-surface impact, front-wheel drives front shock absorber and swings up and down together, makes damping spring in the front shock absorber power that directly withstands shocks, and so not only the making of spring is had relatively high expectations, and because of after spring is subjected to shar pounding, easily cause spring fatigue, and reduce damping effect, and shorten the service life of damping spring.On the other hand, because of two front shock absorbers and the preceding standpipe of preceding damping is integral structure, in order to reach the damping effect of front shock absorber, the volume of front shock absorber is relatively large usually, not only complex manufacturing technology, and manufacturing cost height.
Summary of the invention
The purpose of this utility model provides a kind of compact conformation, good damping effect, and can reduce damping before the Electrical Bicycle of manufacturing cost.
The utility model is that the technical scheme that achieves the above object is: damping before a kind of Electrical Bicycle, standpipe and two front shock absorbers before comprising, it is characterized in that: before described captive joint with two rearmounted boxed rods in the standpipe bottom, the upper articulation of the rear portion of two boxed rods and two lower links, the bottom of two lower links is provided with the front axle mount pad, the two ends of two front shock absorbers are hinged on respectively on two boxed rods and two lower links, and boxed rod, boxed rod and front shock absorber constitute three bar linkage structures.
Wherein: described two boxed rods are curved, and boxed rod top is fixed with crossbeam, and preceding standpipe is captiveed joint with two crossbeams, and the rear portion of boxed rod is provided with the back hinged seat; Described two lower links and tie-beam be fixing to constitute H shape structure, and two lower link tops have last hinged seat, and bearing pin is installed on the last hinged seat of the back hinged seat of boxed rod and lower link, and afterwards is provided with wear-resistant sleeve between hinged seat and the last hinged seat.
The boxed rod and the lower link of the utility model front shock absorber mechanism are hinged, the two ends of its front shock absorber are hinged with boxed rod and lower link again, therefore behind three bar linkage structures that after employing is hinged by boxed rod, lower link and front shock absorber, constitute, after vehicle is subjected to ground-surface impulsive force, when front-wheel drives the upper and lower together swing of lower link, the interior damping spring of front shock absorber is also gone up swing down, because the impulsive force of part is reached boxed rod by lower link, and improve the front shock absorber force-bearing situation.Damping before of the present utility model improves bicyclist's traveling comfort owing to obviously improved damping effect, has effectively avoided the intense impact to the front shock absorber damping spring, so prolong the service life that subtracts the foreshock device, dwindles the volume of front shock absorber.The utility model adopts the three-link mechanism that is made of boxed rod, lower link and front shock absorber, and is stressed reasonable, compact conformation, and damping has stability and rigidity preferably before making.
