As above constitute the spring energy-storage formula bicycle with stepless speed change of present embodiment.

In this spring energy-storage formula bicycle with stepless speed change when operation,, both feet alternately treadle, and phase difference is that the bent axle 22 on 180 ° the bent axle 21 in left side and right side is along clockwise rotating.Connecting rod 27 and the connecting rod 28 driven left side on right side and the actuator 29 on right side through the left side advance through two actuator driven bicycles.Below, with the operational process of the actuator 28 on right side the driving process is described:

When stepping on the pedal on right side, the bent axle 22 on right side is along clockwise rotating, when the connecting rod 28 on pulling right side travels forward, the journal stirrup 40 of the outer runner 38 in the actuator 28 on connecting rod pulling right side is along rotating counterclockwise, make on the outer runner cylinder ratchet 51 press in ratchet 48 and in promoting runner 30 rotate counterclockwise, energy stroage spring 69 with the rotation of interior runner gradually rolling-in accumulate the spring energy.When connecting rod 28 front ends forward the place ahead end position to, the push rod 53 ejection cylinder ratchets 51 of rod rear end rotate counterclockwise, because the arc surface of interior ratchet 48 front ends is pressed on the face of cylinder of cylinder ratchet 51, ratchet is along clockwise rotating in making, leave until the slippage from the cylinder ratchet of interior ratchet front end, at this moment interior runner is discharged relatively together with the inner of energy stroage spring, energy stroage spring release spring energy, runner clickwise in the pulling, outer ratchet 45 in making on the runner and handle ratchet wheel 43 engagements, promote handle ratchet wheel and clockwise rotate, drive bicycle and advance fast together with wheel hub and wheel 6 thereof.After connecting rod 28 front ends turned over limit the place ahead, connecting rod oppositely and backward moved, and promoted outer runner 38 and oppositely turned round up to resetting along cw.Outside runner 38 oppositely when clockwise rotating and interior runner rotate in the same way, this moment is because the rotating speed of outer runner is significantly less than the rotating speed of interior runner, therefore, energy storage projection 34 on the interior runner can impact the block 42 on the outer runner, outer runner is rotated with interior runner, thereby the part spring force that reclaims pulls back connecting rod 28 motions on right side, and the connecting rod 27 by crank 20, axis 17, bent axle 21 pulling left sides travels forward again.When interior runner continuation clockwise rotated stall projection 35 impact fixed stops 37 with low speed, runner stopped operating in making.Because wheel continues to clockwise rotate under the force of inertia effect and advances, wheel still continues to clockwise rotate together with wheel hub, handle ratchet wheel 43, handle ratchet wheel 43 and outer ratchet 45 jump out of meshs.Bicycle moves under the force of inertia effect.

When the connecting rod 28 on above-mentioned right side drives in the process that the actuator on right sides resets, the actuator that the connecting rod 27 in left side drives the left side repeats the operational process of the actuator on above-mentioned right side.After the actuator on right side resets, under the drive of connecting rod 28, repeat above-mentioned operational process once more.So rerun, and about alternately drive bicycle and advance.

When needs are adjusted the speed of advance of bicycle, handle speed regulating handle, regulate the tightness of the coiling of energy stroage spring 69 through the outer end of thin steel rope 70 pulling energy stroage springs, regulate the pre-elastic force of energy stroage spring 69, regulate the driving elastic force of energy stroage spring, thereby regulate the speed of bicycle.

The function of forward-reverse freely of the bicycle of present embodiment, be achieved in that when interior runner 30 clockwise rotates be fixed positive stop 66, backstop 68 on the link stopper seat 63 of formula of the lower end spring bar of the spring shift fork 60 on the interior runner stirred circle and laid in the spring energy around holding.Can stir the trip ring when big and clockwise rotate when the spring at the spring shift fork can be increased to enough.When trip ring turns to pawl slot when outer ratchet 45 slips over, outer ratchet is pressed in the outer pawl base 44, discharge the engagement of outer ratchet and handle ratchet wheel 43.Promptly discharge the constraint to wheel hub and wheel 6 thereof, make the wheel can freely rotate, bicycle is forward-reverse freely just.

The bicycle of present embodiment when the energy stroage spring brisement, when even energy stroage spring not being installed, under the driving of piston crank mechanism, still can drive bicycle and advance.At this moment, when the connecting rod 28 on right side moves backward, spur outer runner 38 and clockwise rotate, the cylinder ratchet 51 ejection stall projections 35 on the outer runner are together with interior runner 30 clickwises, and the detent mechanism drive wheels is rotated outside ingear, and bicycle advances.Meanwhile, the outer runner on the actuator on the left of the connecting rod 27 in left side spurs forward, through the engaged transmission of interior detent mechanism, runner 30 rotates counterclockwise in the pulling, and outer detent mechanism engaged transmission is discharged, and the actuator in left side separates with the transmission of wheel.The connecting rod 28 on right side travels forward subsequently, and the outer detent mechanism engaged transmission in the actuator on right side discharges, and the actuator on right side separates with the transmission of wheel.Meanwhile, the connecting rod in left side moves backward, and through the driver drives wheel in left side, bicycle advances.So the driven bicycle advances.
