Abstract
The utility model relates to a winding type bicycle, which is that axle sleeves used for the swinging movement of the left and right cranks to the bicycle frame are added and the two semiaxles in the axle sleeves are in detaching motion. The left and the right pendulum bars on the cranks are respectively connected to one end of the left and right chains; the other ends are fixed to the coaxial coupling left and right grooved pulleys after respectively engaging the left and the right flywheels; the pendulum bars wind a plurality of rings of chains to one of the grooved pulley aforehand. Pedalling the left and the right cranks can respectively drive the left and the right flywheel to drive the bicycle to advance. The swinging movement is realized by the alternating actions that one grooved pulley releases the pre-wind chains and the other grooved pulley rolles the chains. The structure is simple and practical.
Description
The utility model relates to a kind of bicycle, and particularly a kind of chain is done coiling---release---reels and to finish the bicycle of crank-swinging.
People have proposed various schemes to pedal type bicycle at present, because crank is only done local swing about 120 °, thereby improved the quality that drives, but because the size of wheel diameter influences the speed and the volume of bicycle again, make crank-swinging influence life-span and finishing again with the steel wire tractive, increase cost again with gear transmission.
The utility model proposes and a kind ofly replace wheel disc, with two coaxial bonded assembly sheaves one end of chain is fixed on and drives left and right sides fork in the sheave groove respectively and do simultaneously and give coiling---release---reciprocating action of reeling is again realized, thereby simplify the structure with fork.
Crank-swinging, winding mechanism is by crank half-axile sleeve (13) left and right sides semiaxis (11), (3), whole left crank (10), left fork (12), right crank (2), the right fork (4) that connects, left and right sides flywheel (18), (7) coiling axle sleeve (16) and wireline reel (14), the left and right sides sheave (15) at fixing wound axle two ends, (6) connect left and right sides fork by left and right sides chain (17), (5) and nibble with left and right sides flywheel again simultaneously that being incorporated in reels in the sheave constitutes.
Accompanying drawing is example structure figure of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model example structure scheme drawing
(A-A ') figure is a birds-eye view
Fig. 2 is the enlarged drawing when making the coiling chain in the sheave
Fig. 3 is takeup type bicycle figure
As shown in the figure: the left crank of takeup type bicycle was contained on the left half axle (11) with whole connection of left fork.A fixing end of left chain (17) on the fork of a left side, the other end are fixed in the groove inner core of left sheave (15) after meshing with left flywheel (18).Right crank was contained on the right axle shaft (3) with whole connection of right fork.A fixing end of right chain on the right fork, the other end through with right flywheel (7) engagement after give earlier in right sheave coiling and be fixed on the groove inner core after a few.Rotate counterclockwise when stepping the right fork of right pedal (1), affect right chain to drive right flywheel work, right sheave begins to discharge the chain that gives coiling simultaneously, right sheave rotates, driving coaxial left sheave rotates in the same way and begins the left chain of reeling, left chain drives left flywheel ratchet and slides backward, and drives left fork and clockwise rotates.
In like manner, step left foot and pedal (9) left fork and rotate counterclockwise and affect left chain, make left flywheel (18) work, simultaneously left sheave discharges chain, and right sheave rotates and the right flywheel ratchet of the right chain of reeling slides backward in the same way simultaneously, and makes right fork reposition.So alternately back and forth, driving bicycle advances.
Left and right sides flywheel is contained on the coaxial bonded assembly axle (8).Axle (8) is the bicycle rear axle sleeve.
The angle of the length decision fork swing of the chain activity of reeling and discharging and scope so as the foot-operated better application of force make ride laborsaving.
Claims (1)
- A kind of bicycle, particularly a kind of takeup type bicycle, it is characterized in that: the crank reciprocally swinging is finished winding mechanism by wireline reel axle sleeve (16) wireline reel (14) and a coaxial bonded assembly left side right sheave of sheave (15) (6) that are fixed on the bicycle rack by winding mechanism, crank half-axile sleeve (13) and left crank (10), the a left side right fork of the right crank of fork (12) (2) (4) by left chain (17) right chain (5) connect the right sheave of left sheave (15) (6) and respectively with left and right sides flywheel (18) (7) engagement, give earlier therein a few chains of coiling in the sheave simultaneously.
