Description
The present invention relates to the driver train and the speed-changing mechanism of rod driven bicycles.
The present invention is particularly useful for that the power that the up-and-down movement of drive spindle produces is transferred to trailing wheel by chain and sprocket wheel and comes bicycle driven, and the speed change of bicycle is to be obtained by the position that changes the pipe link that connects chain and shifting arm.Should be understood that " bicycle " speech comprises that also other drive and have the vehicle of the wheel of varying number with the same manner, for example three-wheel vehicle etc.
Traditional bicycle major part is that the circulatory motion by crank pedal drives.Yet 360 ° of rotations of crank have only seldom that a part is used for promoting bicycle, and the remainder that rotates has been wasted.Therefore the motroist will consume more energy and soon feel tired under identical riving condition.Because when driving traditional bicycle, the stroke of pedal can not be regulated and must commentaries on classics one put in order circle, will feel under the weather if motroist's physical condition is not suitable for the annular rotational travel of crank pedal.In addition, the speed change of standard bicycle will adopt the sprocket wheel that is installed in the various sizes on the same axle, and complex structure, heaviness need bigger kinergety.Because chain can be thrown off with change wheel during walking, so often need the refitting chain that stops.
Though someone advised the rod driven bicycles that the up-and-down movement by drive spindle drives, the mechanism that kinergety is transferred to rear axle can't be satisfactory.Often quadrant gear (fan-type gear) or tooth bar are connected on the drive spindle and and are installed in transmission gear engagement in the rotating shaft of trailing wheel.Bicycle by tooth bar or quadrant gear repeat seesaw or up-and-down movement drives.When motion in the position, top of drive spindle or when the position stops at the end, the momentum of tooth bar or quadrant gear is transferred on the gear of trailing wheel with the form of impacting.Like this, drive and just be accompanied by the serious impact of repetition, and occur unsettled phenomenon easily.Particularly, in the driver train claw of free wheel and ratchet since serious repetitive shock engage and wear and tear rapidly with separating even damage.In addition, obtain speed change by the length that changes shifter bar.Connecting pin on the pipe link of the quadrant gear of trailing wheel transmission or tooth bar is inserted on the shifter bar in the slotted eye in the emissions groove hole, and this shifter bar is driven by the speed change steel wire and moves up and down, and the speed change steel wire is handled by actuating speed control stalk up and down.Yet connecting pin bears sizable load when operation, and this load is done can add when drawing moves at the speed control bar and focused under this heavy duty, is difficult to handle little speed control bar with mobile connecting pin with hand.The motroist will stop car when carrying out speed change, and it is difficult wanting speed change when bicycle is advanced.Although drive the required energy of this bicycle more than much smaller by the required energy of the standard bicycle of the annular rotating drive of crank pedal.Above-mentioned problem is unfavorable for the practical application of rod driven bicycles.
The purpose of this invention is to provide a kind of driver train of improved rod driven bicycles and speed-changing mechanism to improve the practicality of bicycle.

Now the accompanying drawing of detailed referential expression embodiments of the invention makes a presentation the present invention, and Fig. 1 has represented a bicycle that includes drive spindle 4 and shifting arm 3.These drive spindles and shifting arm are one, are installed on the shaft portion 2 of side arm 1 bottom of bicycle.The component assembly of drive spindle 4 and shifting arm 3 is with being pivotally mounted on the axle 2, so that drive spindle 4 is made up-down alternative motion (swing) by pedal 4.Drive spindle 4 is kept at an angle with respect to shifting arm 3." and the size of pipe link 14 that shifting arm is a little a bit crooked, and amount of bow depends on vehicle frame and chain 7.Therefore, pipe link moves along specific serpentine track, chain 7 " is connected with shifting arm 3 with pipe link 14.Guide wheel 13 supporting back and forth steel rope 7 '.The hind axle part 2 of vehicle frame 1 ' bottom after the free wheel 11a of one-way clutch mechanism and sprocket wheel 7 are installed in together ' on.Shown in the upper right corner among Fig. 3, hind axle part 2 ' rear wheel assembly form by axle 5 and wheel hub 6.Plate shaped flange 8 have several inclined grooves 8 along garden post surface disposed at equal distance '.Plate shaped flange 8 links to each other with sprocket wheel 7.Each inclined groove be equipped with hard roller 9 and spring 9 '.Plate shaped flange 8 devices have claw 10 and ratchet 10 ' cylinder 11 in, the shape that claw 10 and ratchet 10 ' the composition Greek alphabet is gone into.This free wheel 11a assembly also is equipped with ratchet 12.Two ratchets are assembled in the two ends of axle.The nose of claw 10 is at spring 10 " thrust under snap in square groove 6 ' interior (seeing Fig. 3 and Fig. 4) on the wheel hub 6.Ratchet 10 ' when moving backward, pinned by ratchet 12.This just makes claw 10 from groove 6 ' interior disengagement.When bicycle travelled forward, roller 9 was compressed on the crevice of post subsurface inclined groove in garden in the garden tube 11.So just the power on the sprocket wheel 7 is transferred on the wheel hub 6 by cylinder 11 and (sees Fig. 3,4 and 5).Can establish several grooves 6 ' so that when moving forward, can mesh again more.
Each shifting arm 3 is equipped with several pivoted members that become row arrangement along its length, and these pivoted members are the shape of corner block 15, are installed on the fixed pivot.Each corner block on the summit on its two limits of triangle, have " U " shape groove 15 '.Form pivotal joint with supporting pin 16.(seeing Fig. 6 and 7) removed in the bottom of spring 16 ' corner block 15 is passed arm downwards.Disposing cam bar 17 in each arm moves as length direction below corner block 15.The projection 17 of cam bar ' number and the number of corner block 15 as many.Cam bar and steel rope 19 ' be connected.Steel rope is walked around reel 18 ' rotated by velocity control knob 18.Knob 18 is assemblied on the cylinder, and this cylinder is equipped with the garden pearl 18 of being passed by spring 18 " " " ', the garden integument pass press against reel 18 ' hole 18 " on.By velocity of rotation control dial 18, cam bar 17 moves to the left or to the right, as shown in Figure 6 and Figure 7.Arbitrary of corner block 15 by the projection on the cam bar 17 17 ' boost and reach outside the edge of shifting arm 3, connecting pin 14 ' can move on this edge.Like this, pipe link 14 snap in automatically " U " shape groove 15 of the piece 15 that stretches out ' in.Realized the change of speed by the connection of pipe link 14 on the diverse location of shifting arm 3.
Among Fig. 3, one group of ball 20 is contained in the seat 21 and by ball race 23 to be held, and with nut 23 it is contained on the axle 5 again.
In the time of by bike, the motroist is sitting on the saddle, holds handlebar, pin be placed on left and right sides pedal 4 ' on.The motroist repeats up-and-down movement (swing).What the angle seat that shifting arm 3 constitutes according to itself and catch bar 4 repeated moves forward and backward.Two shifting arms replace traction bars 14 makes chain 7 " makes preceding crank motion.Sprocket wheel 7 is with the both direction alternate rotation.If sprocket wheel 7 clockwise rotates, plate shaped flange also rotates with equidirectional, roller 9 upwards roll into adjacent grooves 8 ' the narrow space of dip plane in go, on the inner periphery of the cylinder that is stuck in free wheel 11a 11 tightly.Force cylinder 11 and free wheel 7 to rotate like this.At this moment and since the nose of the claw 10 in the cylinder 11 be stuck in the square groove 6 of wheel hub 6 ' in, shown in Fig. 4 (B), so wheel hub 6 also rotates with equidirectional and drives bicycle and move forward.
" roller 9 in plate shaped flange groove is rolled into the wider portion of groove downwards and is separated from the cylinder 11 of free wheel 11a for backward rotation, perhaps sprocket wheel 7 transfixions when bicycle slides if sprocket wheel 7 is by chain 7.Therefore the backward rotation of sprocket wheel 7 does not pass on the cylinder, wheel hub 6 since amount of spin still forward plane of rotation be not subjected to sprocket wheel 7 counter-rotational influences.When sprocket wheel 7 again when direction of propulsion rotates, plate shaped flange 8 and cylinder 11 are clamped together again power are transferred on the wheel hub 6.Therefore, when catch bar 4 moved up and down, the power that is produced was transferred to sprocket wheel 7 and goes with the free wheel 11a that is installed in rear axle 5 two ends, and bicycle just continuously to overtake.
When needing speed change, velocity of rotation control dial 18, cam bar 17 is moved, and promotes to dispose in the shifting arm 3 first pivot block 15 of the most close axle 2 in many pivot blocks 15 of embarking on journey, shown in Fig. 7 (D).Like this, the connecting pin 14 on the pipe link 14 ' just by the moving surface of the weight of pipe link self and shifting arm 3 snap in automatically first 15 " V " shape groove 15 ' in, the result forms first speed of dead slow.Shown in Fig. 7 (E), the second pivot corner block 15 is pushed out, and the connecting pin on the pipe link 14 snaps onto on second corner block 15, has obtained second speed a little hurry up.Connecting pin 14 snaps onto on the 3rd corner block if the 3rd corner block 15 is pushed out, and shown in Fig. 7 (F), has just obtained the 3rd speed more hurry up.In such a way, the speed change knob is rotated, be stuck in connecting pin 14 on the shifting arm ' the position be changed changing the effective length of shifting arm, thereby obtained needed speed change.
When bicycle moves backward, during its wheel backward rotation, on the tooth of ratchet 10 ' snap in ratchet 12 and claw 10 upwards push away square groove 6 from wheel hub 6 ' be separated from, as scheming shown in (C).Like this, have only wheel hub 6 to rotate and free wheel 11a and sprocket wheel 7 do not change.Therefore bicycle is the same with standard bicycle, can travel backward and slide and do not cause moving up and down of drive spindle.
The bicycle that promotes according to bicycle of the present invention and traditional bicycle and other rod-types is compared has following advantage, because the design of bicycle so that drum-type free wheel and sprocket wheel link together, be installed in the two ends of rear axle, chain is installed in reciprocating motion is provided on the sprocket wheel. The connecting rod that links to each other with chain with and group of drive rods all-in-one-piece shifting arm connect together. Bicycle by pedal move up and down drive. The angle of this motion can and make things convenient for situation to determine according to motroist's physical condition. Like this, that the cyclist just can be more comfortable and light. Simultaneously, can be transferred to fully wheel hub by sprocket wheel and free wheel by the drive rod power of transmitting that moves up and down. Like this, energy is waste not, only needs very little power in the time of by bike. In addition, the leg exercise that drive rod is moved up and down is similar with the action of the usual walking of people. Therefore, even the beginner can any special training, and to operate bicycle with the identical mode of walking. The caused impact of its momentum can be avoided the serious impact to the drive unit of hind axle part when motion stopped at forward and backward extreme position backward forward because the flexibility of chain can reduce shifting arm. Can transmit smoothly power by the drum-type free wheel. The reliability of drive unit and Service life, the time of bicycle operation can lengthen.
In addition, a lot of corner blocks in a row are installed on the shifting arm with pivot, can selectively release outside the shifting arm by the cam bar that velocity control knob is handled for its any one, connecting pin on the connecting rod end snaps onto on the piece that stretches out, therefore in addition bicycle when walking, also can obtain needed speed change. The speed of a motor vehicle depends on the road surface situation, and ascents and descents for example is more comfortable and more convenient when guaranteeing by bike.
