The specific embodiment
According to Fig. 1-shown in Figure 5, the utility model mainly comprises: left flywheel hub 1, steel wire 2, steel ring 3, right threading chain drum 4, left threading chain drum 5, right chain 6, left chain 7, right flywheel 8, left flywheel 9, flywheel detent mechanism 10, detent mechanism bearing cap shim 11, flywheel ratchet device 12, cylindrical pin 13, rear axle 14, axis 15, right flywheel hub 16.
The position is arranged with left flywheel 9 and right flywheel 8 respectively before and after on the trailing wheel of bicycle, and left flywheel 9 flexibly connects through rear axle 14 and right flywheel 8; Left side flywheel 9 and right flywheel 8 are established flywheel detent mechanism 10, detent mechanism bearing cap shim 11, flywheel ratchet device 12 in respectively; Flywheel ratchet device 12 is through being inserted in 10 both flexible connections of flywheel detent mechanism, and detent mechanism bearing cap shim 11 is captiveed joint with flywheel ratchet device 12; Flywheel detent mechanism 10 is inserted in left flywheel hub 1, right flywheel hub 16 respectively through cylindrical pin 13; Rear axle 14 is inserted in left flywheel hub 1, right flywheel hub 16; Left side flywheel 9 flexibly connects with left threading chain drum 5, right threading chain drum 4 through left chain 7, right chain 6 respectively with right flywheel 8, and left threading chain drum 5 flexibly connects through axis 15 and right threading chain drum 4.
Left side flywheel hub 1 is captiveed joint with steel ring 3 through many steel wires 2 along circumference.
Principle of work:
Structure is made up of chain drum, chain, flywheel, free wheel base; The independent chain gearing of one cover is installed on the left side of bicycle.
Chain drum is installed on the left side of axis; And, do not allow it loosening with pin locking chain drum and axis, free wheel base is connected with the trailing wheel axle sleeve; Connect the back form the rear axle both sides respectively have a free wheel base again 20 apertures from the left side free wheel base 1 set up steel wire (being rung) successively; Connect bicycle rim, correct bar, steel wire on the steel ring, finally form 2 auxiliary transmissions.
When riding chain drum on the right of rotating, chain drives right back flywheel and rotates, and the foot-operated chain drum in the left side also drives left back flywheel rotation (being that left and right 2 auxiliary transmissions are worked simultaneously) by chain thereupon simultaneously.
When rotating the foot-operated chain drum in the left side, left chain drives left flywheel 4 and rotates, the right threading chain drum also drives right flywheel by right chain thereupon and rotates simultaneously.(promptly forming the both sides driving device works simultaneously)
Axis former foot-operated arm in the bicycle left side is disassembled, load onto the foot-operated chain drum of band, the number of teeth is 44 teeth, and loads onto pin chain lock stressed joint position.
Get 1 flywheel (20 tooth) and 1 flywheel hub that 20 apertures are arranged; Take the detent mechanism bearing cap shim earlier apart, unload the flywheel detent mechanism, take off check pawl and spring; Bore the circular hole of a 3MM with electric hand drill at the spring position; There have the detent mechanism one side to tighten (the detent mechanism negative thread connects the flywheel hub outside thread) towards the connection of flywheel hub outside thread to be shown in Figure 4, in the hole, marks a mark " O " shape in its drill hole with draw point, unclamps detent mechanism and flywheel hub afterwards; At this moment the next one " 0 " shape mark is stayed at flywheel hub outside thread place; Also bore a 3MM aperture in center-point " ⊙ " position, (effect is to assemble at last the fashionable dress pin and fixes, and plays a device that can transmit power).
Pull down trailing wheel; Unclamp 20 rungs (steel wire) on the wheel hub of the left side and unload down with special tool, pull down left side wheel hub simultaneously and load onto one 20 aperture flywheel hubs are arranged, next step loads onto 20 rungs (steel wire) by former rung position; Also unclamp the rung nut on former the right; Put " school circle " device, tighten steel wire (rung) nut up and down and proofread and correct steel ring, forming the left and right both sides of rear axle at last respectively has a flywheel hub.
Screw in tapped detent mechanism in the flywheel hub outside thread and to tighten, align the pin hole ratchet device of packing into after the dowel fixes of packing into, tighten bearing cap shim, form 1 fly wheel assembly at last.
Next dismantle original ripple cup and ripple pearl bearing in the wheel hub of rear axle both sides, wave crest; (effect is to change original wave crest and the wearing and tearing of ripple pearl bearing fatiguability to load onto 2 ball bearing of main shafts; Wave crest, ripple pearl are lost circle; Cause the abnormal sound that gone, effort, advantage is that frictional resistance is little, sensitive, efficient is high, easy to maintenance.)
Load onto suitable bearing cap shim (not allowing its flywheel to run on the vehicle frame) on the rear axle both sides; Rear axle and 2 fly wheel assemblies assembling are packed on the vehicle frame; Connect left threading chain drum and left flywheel with left chain; Adjust left and right both sides chain tension degree, tighten rear axle both sides nut at last and promptly form double-stranded bar bicycle.
