Description
Affiliated technical field
The utility model relates to a kind of driving device of reciprocating type driving small-wheel bicycle.
Background technology
Small-wheel bicycle is surging forward, and it is small and exquisite that the small-wheel bicycle of reciprocating type driving has car body, drives labour-saving volt property more.And to reach the requirement of reciprocating type driving small-wheel bicycle, the driving device that must have a cover to adapt with it.
Summary of the invention
For solving the transmission problem of reciprocating type driving small-wheel bicycle, the utility model provides a kind of driving device, and this device both can reach the requirement of reciprocal driving effectively, can increase transmitting ratio again to improve the speed of a motor vehicle.
The utility model is that the technical scheme that its technical matters of solution is adopted is: this programme branch has tooth flywheel and two kinds of versions of anodontia flywheel.A kind of is to have the next door of tooth flywheel that a sprocket wheel is installed at each, the diameter of sprocket wheel is greater than the diameter of flywheel, by chain gear, driver trains such as that an end of chain connects is foot-operated, hand lever, an end are walked around and are twined sprocket wheel again behind the flywheel and be fixed on the teeth of sprocket wheel.Sprocket shaft is installed in car and sticks, and suit is twisted spring on the sprocket shaft, and an end of twisting spring connects sprocket wheel, other end connection chain wheel shaft or car fork.Second kind of structure be, adopts anodontia flywheel, by the steel rope transmission, two kinds of ways arranged, the one, and anodontia flywheel outer ring has pulley groove, and the 2nd, the flywheel outer ring is with the external pulley of bolt.One end of steel rope is connected with driver train power, and other end coiling pulley also is fixed in the groove.Suit is twisted spring on the wheel shaft at close anodontia flywheel or pulley place, and an end of twisting spring connects anodontia flywheel outer ring or pulley, and the other end connects stubborn spring card or car is pitched.
Bicycle divides two-wheel car and three-wheel vehicle etc.A flywheel and driving device respectively are installed on two wheel hubs of single driven wheel; On a side wheel hub of dual drive wheel (being all drive wheel), a flywheel and driving device are installed respectively as two trailing wheels; Two flywheels are installed in the middle of the double rear wheel axle side by side, and flywheel drives the wheel shaft revolution, and a cover driving device respectively is installed in the outside of two flywheels.
Small-wheel bicycle will guarantee that the speed of a motor vehicle must adopt bigger transmitting ratio, and will increase speed ratio, in rotary driving, or strengthens driving wheel, or reduces follower (being flywheel).In reciprocating type driving, can increase and drive traverse to increase speed ratio, the utility model is in having the tooth flywheel structure, because sprocket diameter is greater than flywheel, so each driving, flywheel is more than the rotatable week, and in anodontia flywheel structure, because that steel rope twines pulley groove is unrestricted, so that each driving also can make flywheel rotate a circle is above.Under the situation that reciprocating type driving traverse is difficult to strengthen, adopt the method for the external pulley of anodontia flywheel, because pulley inside groove diameter is obviously littler than flywheel race diameter, amplify transmitting ratio so reduce the follower diameter.
The beneficial effects of the utility model are, this transmission structures is simple, and stable performance not only adapts to the requirement of reciprocating type driving, and can increase transmitting ratio, and this device extensively Ying Yu also can be applicable in other mechanical drive with small-wheel bicycle, Kickboard Scooter.
