Description
Technical field
The utility model relates to bicycle, relates in particular to a kind of vibrations of travelling that alleviate, and reduces advance resistance, and its shock absorption device produces the bicycle of the band shock-absorbing boosting device of forward thrust to vehicle driving.
Background technology
At present, ordinary bicycle all is a rigid construction, and the road surface has slightly and coarsely will produce strong concussion and produce very big advance resistance.When bicycle met obstacle at a high speed, the people will be subjected to the impact of front and back wheel secondary concussion.Also have some to have the bicycle of shock-damping structure front fork now, it mainly is divided into two classes: a class is that damping spring is installed on the tubulose of front fork in the shoulder, can realize alleviating the vibrations of front-wheel, but the damping point in the last shoulder is subjected on the folding fulcrum in resistance point that bicycle advances and promotion force just, form opposite resistance, cause front fork to damage easily, durable inadequately, efficient is lower; Another kind of is that two damping springs are installed in respectively in the bipod pipe of front fork, can realize damping equally, but the potential energy that partly advances is offset in its damping simultaneously, can't provide the propelling thrust that advances for bicycle.
Aspect in addition, some bicycles have the shock-damping structure of vehicle frame and saddle, its structure generally is that the damping spring cover is through on the vertical beam of saddle below, or directly is connected as all or part of and bottom girder of vertical beam, and the axis of damping spring axis and vertical beam bar is on the same vertical line substantially.Above-mentioned two kinds of shock-damping structures can be realized the cycle frame damping, but the user jumps up generation counteract gravity forces damping spring when falling to the forward thrust of vehicle frame at bicycle, and shock-damping structure can't provide the propelling thrust that advances for bicycle equally.
Summary of the invention
The utility model purpose is to provide and can effectively reduces bicycle running vibrations, reduces advance resistance, simultaneously damping potential energy is converted into the advance bicycle of potential energy band shock-absorbing boosting device of bicycle.
The bicycle of band shock-absorbing boosting device of the present utility model comprises vehicle frame, saddle, handlebar, front fork, front wheel spindle, hind axle; Wherein vehicle frame comprises the vertical beam that supports saddle, the bottom girder that damping spring connects hind axle; Front fork comprises fork shoulder, fork pin, device front fork damping spring in the tubulose fork pin is characterized in that: in the portion of tubulose fork underfooting active pull rod is housed, spring and nut are installed in the pull bar upper end, the bottom covers a spring perch, and the front fork damping spring is blocked limit between spring cover and spring perch; Fork pin tip forward below is stretched out one and is prolonged piece, prolongs piece and is connected with front wheel spindle by the rocker interlinked mechanism with pull bar.
Above-mentioned interlinked mechanism comprises a rocker, and the front end of rocker is fixed on the front wheel spindle, and the rocker middle part articulates with prolonging the piece end, and pull bar lower end and rocker rear end flexibly connect; Described flexible connection form is the direct and rocker rear end pivot joint in pull bar lower end, or pull bar lower end active section articulates the rocker rear end.
Front-wheel just produces jump with ground-surface, the damping spring compressing rocker repeatedly of while front fork, and rocker promotes front-wheel forward.Just, when front-wheel takeoffs because of Uneven road, rocker compressing pull bar, pull bar roof pressure front fork damping spring, damping spring shrinks, and reduces the vehicle body vibrations; When front-wheel fell, damping spring discharged, the roof pressure pull bar, and pulling rocker rear end makes progress, and the rocker front end is corresponding to front lower place pushing tow front-wheel, makes vehicle body forward.Rocker is whenever upwards risen once by front-wheel, is just producing to drive vehicle body to reach power once, and the size of this power rises and falls with front-wheel and is directly proportional.When driving, the application force that the front fork damping spring promotes is repeatedly saved bicycle driver strength greatly.
Described vertical beam is two sections of broken line shape, and epimere is vertically and with bicycle saddle to be connected, hypomere to the bicycle rear extension and be connected bottom girder, all or part of installation vehicle frame damping spring of hypomere wherein.
When vehicle body takeoff, the vehicle frame damping spring shrank and discharges, and reduced the vehicle body vibrations; Produce go-cart body power forward simultaneously, can be divided into vertical direction and act on the power of saddle and promote vehicle body horizontal thrust forward.
The power-assisted bicycle of band shock absorption device of the present utility model, main by transformation to front fork shock-damping structure and vehicle frame shock-damping structure, not only can effectively reduce bicycle running produce vibrations, reduce advance resistance and damping potential energy can be converted into the bicycle potential energy that advances simultaneously; In addition, front fork directly is not connected with the bicycle front wheel spindle, reduces front fork and is subjected to such an extent that impact, and prolongs front fork and part service life.
