Description
Technical field
The utility model is related to a kind of bicycle, more particularly to a kind of multi-functional driving bicycle.
Background technology
Bicycle, from incoming China of western countries, also known as bicycle or bicycle, the small-sized ground vehicles of typically two wheels.
Present bicycle various regions all over the world, are the most common vehicles of people into every household.People is ridden after car, is stepped on pin
Pedal is power, is the vehicles of environmental protection.
Bicycle is to overcome one of optimal instrument of cardiac function defect.It is to die from heart to have people more than half in the world
Disease.Bike riding can not only by leg motion compresses blood flow, and blood from blood vessel distal drawn back heart, in fact
But microvascular tissue is enhanced simultaneously, this is cried " subsidiary circulation ".Reinforcing blood vessel can be such that you is not threatened by the age, and the youth is forever
Stay.
In addition, habitually cycling, more can gradually expand your heart.Otherwise blood vessel is more and more thin, heart
More and more degenerate, to old age, you will experience the worry that it comes, at that time you, it can be seen that cycling be how
It is perfect.
Bicycle is to need the motion of a large amount of oxygen, once has individual the elderly with 6 day time, completes 460 kilometers of bicycle
Travelling.He says：" the elderly will at least have 3 motions for one week, strengthen heart, recover normal function.You should swash heart
Strong bounce, but can not be too long.So it will adapt to emergency, such as drive a cart or resist predicament ".
Cycling can also prevent hypertension simultaneously, sometimes more more effective than medicine.Can also prevent from getting fat, vascular sclerosis, and
Make bone strong.Bicycle makes you to maintain health with medicine, and has no harm.Bicycle is the instrument of fat-reducing, root
According to statistics, the people of 75 kiloponds, per hour with 9 mile half of speed, rides 73 miles per hours, can reduce by half kg body weight, but necessary
It is persevering daily.
Cycling, may not only lose weight, and your figure can also be made more well-balanced charming.Keep fit through sport, or margin knot
The people for eating side motion, stature is more preferable than the people Lai get only by fat-reducing of going on a diet, more charming.Appropriate motion can secrete a kind of He Er
Cover, this hormone makes you be cheerful and open, in high spirits.From experience, it is to be understood that cycling just can produce this hormone.
In fact because stepping on bicycle compression blood vessel so that blood circulation accelerates, and brain takes in more oxygen, therefore you inhale
More fresh airs are entered.Ride through after a period of time, you can think that brains become apparent from.Ride and this go what is stepped on by this body forces
Two-wheel bicycle, you can feel very free and make us happy incomparable.A kind of its not just weight reducing exercise, even more soul pleasure
Banish.
But present bicycle has the disadvantages that：Function is single, substantially just only moveable endless, it is necessary to bicyclist
Driving can be realized by trampling, the bicycle price with other functions again costly, it is impossible to meet most consumers
Requirement.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of multi-functional driving bicycle, this reality
Adopted the following technical scheme that with new：A kind of multi-functional driving bicycle, including vehicle frame, guidance system, drive system and system
Dynamic system, guidance system is made up of parts such as handlebar, front fork, front axle, front-wheels.Rider can change row by manipulating handlebar
Sail direction and keep car body balance.Driving（Transmission is walked）System by pedal, axis, chain wheel, crank, chain, flywheel, after
The parts such as axle, trailing wheel are constituted.The power of pedaling of the pin of people is the part transmission such as sprocket wheel, chain, flywheel, rear axle by crank by pedal
, so that bicycle constantly advances.Brakes is made up of brake part, rider can manipulate brake at any time, makes traveling
Bicycle slow down, stagnation of movement, it is ensured that traffic safety.The drive system include pedal, axis, chain wheel, crank, chain, flywheel,
Rear axle and trailing wheel, are equiped with easy-to-dismount nut, shell fragment, bearing, chain wheel and crank successively on the side of the axis,
Easy-to-dismount nut, shell fragment, bearing and crank, the end connection of the crank are equiped with the opposite side of the axis successively
There is pedal, the crank is vertical with the pedal.
It is preferred that, the shell fragment is common shell fragment, and crank rotates around axis 360, and what bicycle was realized is exactly common pin
Step on function.
It is preferred that, the shell fragment is attached most importance to pendulum shell fragment, and the heavy pendulum shell fragment includes pendulum elastic sheet body again and weight goods of furniture for display rather than for use, described heavy
Pendulum elastic sheet body and weight goods of furniture for display rather than for use are hinged, and weight goods of furniture for display rather than for use can rotate around hinged place, can thus realize 90 ° of -150 ° of models of bicyclist
That encloses tramples, and crank is after middle shaft rotation to certain angle, and the weight that shell fragment is put again will be because of the weight automatic rotary of itself
Lowest part is gone to, so that foot-operated reset, what such bicycle was realized is exactly the function of marking time.
It is preferred that, the bearing is unilateral bearing.Unilateral bearing is can freely to rotate in one direction, and another
Locked a kind of bearing on individual direction.Unilateral bearing is also freewheel clutch, simply different according to industry, acts on difference to name
's.In the metal shell of unilateral bearing, comprising many roller bearings, needle roller or ball, and it rolls seat（Cave）Shape make it
It can only be rolled to a direction, and very big resistance can be produced in the other directions.A left side can just be realized using unilateral bearing
The pedal on the right each realizes different functions, non-interference so that deleterious effect will not be produced.
It is preferred that, the chain wheel is split type chain wheel.Using split type chain wheel it is simple to operate, be easy to dismounting, be conducive to reality
The conversion of existing a variety of type of drive, so that a single bicycle just has the function of many bicycles.
It is preferred that, the nut is goat's horn nut.Goat's horn nut have be easily installed, good integrity, without packing ring, dismounting
The advantages of convenient, reusable medium carbon steel is made.
It is preferred that, the end being connected in the crank with axis is provided with rubber cork.Provided with rubber cork convenient disassembly, and
And can form a closed space relatively, it is to avoid and the entrance of extraneous dust etc., prevent the mill to parts such as bearings
Damage, be conducive to extending the service life of bicycle.Gap is left between the rubber cork and the shell fragment, so in axis
When rotation, rubber cork, there will be no contacting, would not also produce friction with shell fragment, so that the driving to bicycle is produced
Resistance, or even the abrasion of parts is produced, so as to influence the service life of bicycle.
Compared with prior art, the beneficial effects of the utility model are：1st, reasonable in design, it is easy to use；2nd, can
A variety of type of drive are realized, a variety of functions can be achieved by the shape for changing shell fragment, are increased again on the basis of original ride
A variety of type of drive such as single foot-operated step, both feet are marked time and both feet jump, meet the multinomial demand of user；3 and cost is low
It is honest and clean, it is only necessary to which that the price of a bicycle is that can realize the function of plurality of bicycles.
