Abstract
The utility model relates to a portable bicycle, a bicycle with a small wheel is booming. In order to overcome the difficult problems that a bicycle with small wheel has high bicycle holders and seat, the utility model adopts a body construction with a small wheel, short wheel spread, and low seat, adopts a reciprocating hacking way that feet step on a low position of the front wheel, and adopts a drive device with double bicycle chains and double flywheels. Compared with the prior bicycles with small wheels, the utility model has smarter bicycle body, more comfortable driving, safer running, more simple structure, and faster speed.
Description
Affiliated technical field
The utility model relates to the portable bicycle of a kind of steamboat.
Background technology
Small-wheel bicycle has to take deposits advantage easily, and be surging forward in the whole world.But small-wheel bicycle is continued to use the rotary type of drive of pedal, so cause vehicle seat high and narrow, the center of gravity of so not only riding is high and dangerous, and takes uncomfortable.
Summary of the invention
Be to solve the not only high but also narrow difficult problem of standard bicycle vehicle seat, the utility model adopts the reciprocating type type of drive of front-wheel, with reach car body small and exquisite, drive purpose comfortable, driving safety.
The technical scheme that the utility model is taked for the technical solution problem is:
The founder of bicycle is exactly wheeled before pedal drives, now to returning Piao and having returned genuine the time.The benefit of front wheel drive type is, the person's of riding legs and feet protract, can reduce the length of car, also can reduce the height of vehicle seat, but also there are three drawbacks: the one, leg is pedaled also and then wheel commentaries on classics when the car coast, the 2nd, can not add big speed ratio, so generally adopt big front-wheel, the 3rd, protract rotary scrunch the mode people feel awkward and the effort.
The utility model adopted 20 o'clock and with lower whorl wheel directly, reduced front and rear wheel wheelspan (two-wheeled is outer intermarginal less than 38cm), adopted the body construction of short and roomy vehicle seat.Adopt long front fork, low hinge, the reciprocal mode that scrunches of the hinged crank of hinge, pedal about the front-wheel both sides (front and back).Adopt the pull bar connection chain bar on long crank (longer), the crank to drive the flywheel revolution, twist spring, make the automatically reset driving device of crank and pedal at the front wheel spindle suit than standard bicycle.The technical scheme concrete analysis is as follows:
1, reduces car body: adopt trundle, and dwindle distance between the front and rear wheel, reduce vehicle seat, the also corresponding reduction of handlebar, make car body small and exquisite (vehicle commander can reach in 1 meter), car weight is also corresponding to be alleviated, and so not only is convenient to take and deposits (folding can leaving in the boot of car), and it is little to take up space in travels down, can improve the degree of utilization of road greatly.
2, reduce vehicle seat: adopt the type of drive of pedal at front-wheel both sides up-and-down reciprocating, the amplitude that not only scrunches is little, and does not occupy activity space in addition, so can reduce the vehicle commander, adds and adopts little trailing wheel, just can significantly reduce vehicle seat.Make the down-shift of working center of car like this, not only operate steadily, and it is very convenient to get on or off the bus, bipod can land easily, has improved the safety of driving so greatly.
3, amplify vehicle seat: adopt the reciprocating type mode that scrunches of front-wheel, the size and shape of vehicle seat no longer is in the way when driving, thus can adopt roomy vehicle seat, ride comfort like this, health is reliable when travelling.
4, scrunch and unfold: the utility model adopt pedal at low level place, front-wheel both sides the upper and lower mode that back and forth scrunches, feel to unfold effectively, two pedals both can drive simultaneously, also can drive by turns, in the time need not driving with pedal, bipod can lie on the pedal that is in low level.
5, driving is laborsaving: the utility model adopts long crank to add large driving force arm (this is that the conventional drive mode is difficult to realize), adopt reciprocating type type of drive simultaneously, can subdue the idle work and the poor efficiency merit of rotary type of drive, so when scrunching, feel very laborsaving.
6, guarantee the speed of a motor vehicle: adopting big slightly front-wheel is in order to guarantee the speed of a motor vehicle when driving.Though front-wheel is big, also belongs to trundle, does not adopt bigger transmitting ratio in order not influence the speed of a motor vehicle.The transmitting ratio that the utility model drives is that the distance from the hinge to the connecting rod just is equivalent to the radius of standard bicycle axis chain wheel, is scalable transmitting ratio so regulate the height of connecting rod, to step on the juice by the height decision of crank boxed rod.
The beneficial effects of the utility model are: than traditional small-wheel bicycle, under the bigger situation of wheel (wheel can reduce resistance greatly), car body is smaller and more exquisite, drive more comfortable, drive more laborsavingly, it is safer to travel, and speed is very fast.Like this, can improve the practicality of small-wheel bicycle greatly.
