Abstract
The utility model discloses a double-driving device of a bicycle, and relates to a bicycle, in particular to a double-driving device of the bicycle. The utility model provides a double-driving device of the bicycle with the advantages of simple structure, convenient use and low cost. The double-driving device is provided with a middle axle, a middle axle sprocket, two middle axle crankshafts, two middle axle pedal axles, two middle axle pedals, a rear axle, a rear axle sprocket and a driving chain. The double-driving device is characterized in that both ends of the rear axle are respectively provided with a rear axle crankshaft, a rear axle pedal axle and a rear axle pedal; connecting rods are respectively arranged between the middle axle crankshaft and the rear axle crankshaft, or between the middle axle pedal axle and the rear axle pedal axle; the phase difference between the two rear axle crankshafts arranged at both of the two ends of the rear axle is 180 degrees.
Description
Technical field
The utility model relates to a kind of bicycle, especially relates to a kind of double-drive device that is used for bicycle.
Background technology
Ordinary bicycle all is single driving, and the band people requires great effort when travelling especially.And double driving bicycle generally is used for the tourist recreation place, often need establish the complete actuating device of 2 covers, causes structure complicated, and cost is higher, is difficult to spread to family and uses.
Notification number is used both hands and feet for the utility model patent of CN2709304 provides a kind of, front and back wheel drives, average velociity significantly improves does not influence the double driving bicycle of basic function flexibly of turning.Technical scheme: be provided with and one have the driving device of (single or) double teeth wheel and crank above the bicycle front-wheel, driving device joins respectively by chain and front wheel spindle upper sprocket wheel both sides, and driving device and handlebar front fork activity post join; Adjustable crank is the crank that both can be used as f-w-d, the arm of force of turning about can doing again.
Notification number provides a kind of two double pedal bicycle that drives for the utility model patent of CN2846275, mainly by wheel,, pedal, flywheel, sprocket wheel, chain, axle, upright pillar, cant beam, back seat, shelf etc. form, owing to below upright pillar of bicycle car and the rear deck seat bumper and spring are housed, good damping effect, it is comfortable that the people feels by bike; The independent transmission device of two covers can be given full play to two people's peak powers; Front stall is lower than back seat, makes the people see direction and road surface situation simultaneously clearly, is furnished with back mirror, helps safety.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to use, bicycle double-drive device that cost is low.
The utility model is provided with axis, axis sprocket wheel, 2 Middle axle cranks, 2 axis pedal axles, 2 axis pedals, rear axle, rear axle sprocket wheel and driving chains; Its characteristics are to be respectively equipped with at the two ends of rear axle rear axle crank, rear axle pedal axle and rear axle pedal, be provided with pipe link between Middle axle crank and the rear axle crank or between axis pedal axle and the rear axle pedal axle, phase difference is 180 degree between the set 2 rear axle cranks in rear axle two ends.
The two ends of pipe link preferably are rotationally connected by bearing and axis pedal axle and rear axle pedal axle.
Compare with existing bicycle double-drive device, because the utility model is respectively equipped with the rear axle crank at the two ends of rear axle, rear axle pedal axle and rear axle pedal, be provided with pipe link between Middle axle crank and the rear axle crank or between axis pedal axle and the rear axle pedal axle, when therefore the utility model uses, only need to be improved according to the actual conditions of ordinary bicycle, for example can set up back seat, or original back seat improved, axis is extended a little, so that the installation of pipe link etc. can realize double two the driving, thereby can reach the purpose of the double driving of ordinary bicycle, save muscle power, increase recreational and interesting.The utility model is simple in structure, easy to use, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
The specific embodiment
Embodiment 1
Referring to Fig. 1, the utility model comprises axis 1,4,2 axis pedals 5 of 3,2 axis pedal axles of 2,2 Middle axle cranks of axis sprocket wheel, driving chain 6, rear axle 7, rear axle sprocket wheel 8; Be respectively equipped with rear axle crank 9 and rear axle pedal axle 10 and rear axle pedal 11 at the two ends of rear axle 4.Be respectively equipped with 2 pipe links 12 between the axis pedal axle 4 of both sides and rear axle pedal axle 10, the two ends of pipe link 12 are rotationally connected by bearing (the figure meta draws) and axis pedal axle 4 and rear axle pedal axle 10.Phase difference 180 degree between 2 rear axle cranks 9 at rear axle 7 two ends.Two ends at axis 1 is respectively equipped with jam nut 13, is respectively equipped with jam nut 14 in the two ends of rear axle 7.
Similar to Example 1, its difference is to be respectively equipped with 2 pipe links between Middle axle crank and rear axle crank.
