Bicycle, say again bike or cycling, usually two rounds of small land vehicles. People rode get with the foot pedal strokes as a driving force, is the green environmental protection of transportation.
Bicycle attribute
Bicycle models
Many countries and regions that bike is vehicles, often calls properly equipped with even to the relevant government departments to register license only after they are on the road. Some local requirements when the car is driven at night bicycle to use headlights. The traffic rules and regulations of the People's Republic of China will be listed as a non motor bike. In Hong Kong, bicycle belongs to "FeiJiDong vehicle", need not licensed ones, but on the road, must observe and motor vehicle as the traffic rules.
Bikes are the most successful man invented a kind of human machinery, and is composed of many simple mechanical compose complex machinery.
In 1790, a French guy named west Cardiff pull grams, he loves thinking. One day, he walked in Paris on a day, because have rained, accumulate a lot of rain, the road is very bad away. Suddenly, an open barouche directly from behind, the road narrower, carriage and very wide, west to hide to Cardiff pull grams hide to but luckily no is knocked down, or were spilled a clay and rain. Others saw, sorry for him, still spirit keep scold, want to shout the cart stopped, reasonable bargaining. West Cardiff pull grams but mumblingly say: "don't shout, don't shout, let them go." Carriage walked away, he also bottom27 stood on the road. He think: road so narrow, pedestrians and so much, why can't the carriage of tectonic altered? Should put the cart along the cut off half, four wheels into before and after two wheels... He such a thought, home is hands on design. Through trial and error, 1791 after the first plane abraao "Trojan wheel" car made out. The car has around two wooden car wheels are among beams and above, attached to put a bench, like a toy edifice. Because the car haven't transmission chain, rely on cyclist with your feet firmly, the car will slowly moving forward, and the car nor steering device, can go straight on, and will not turn, go out riding soon tired sweating like a pig.
Just appear new things are not so perfect. West Cardiff pull not discouraged, he continued to gram think method was improved. Unfortunately, his illness soon died.
1816 in Germany have a look Lin man named Della alois, he CunDong daily from this piece of wood, and go into village west another slice of the woods, it happens every year. He think: if people sitting on your car, considerable stop-and-go, follow one's inclinations, is not very handsome? DE rice began making MuLun car, appearance with west Cardiff pull grams made almost. However, in the front adds a control direction, so as to change the car traverse direction. But still have to ride with two feet, about a shimoji stamped on the ground, can promote the car rolling forward. When DE rice to ride a bike to go out, all the way was test of many people laugh. Despite this, he still loves his creative this frame "lovely pony pups". A German rice in cycling netherwhelp open over a carriage wagoner laughed at him, said his car slowly, so he went and driver say: "you letter not letter I car faster than your carriage" and the two of them made a bet. Journey from CunDong to village west back and forth, the result DE rice than coachman whole fast 1 hours.
In 1840, England's hammersmith McMillon, got a car shabby "lovely pony pups". In his rear axle is installed on the crank, reoccupy connecting the cranks and front pedal connected, and simply use iron, front wheel big, rear wheel is small. When cyclists pedal, car pedaled themselves the movement, ran forward. This would make cyclist feet off the ground with both feet, true of alternating pedaled into wheel rolling, greatly raising speed. In 1842, macmillan? This car ride on, one day run twenty kilometers, because not be careful, trample too fast, the speed of a car knocked down the road of a little girl, and therefore have been caught by the policemen, and impose a fine. Their names had been "savage ride". In 1861, French meters shaw, father and son profession is originally carriage repair goldsmiths, they are fitted in front of pedal board; pivoted The car in front of saddle gestell above, so unless cycling techniques are particularly superb, otherwise it will catch instability handlebar, will fall off from the car. They put the two wheels dubbed "bicycle" YaMing, and in 1867 in Paris exposition on display, let the audience eyes.
In 1869, the British Renault watched French bike later, feel the car's too heavy, and began to mull over the bicycle doing some lighter. He adopted the wire spokes to tighten rim as wheels, At the same time, using fine steel bar to make frame, front wheel is larger, the rear car is smaller. So that bicycle itself weight reduce some. From the beginning, always Cardiff pull grams to Renault, they make five types of bicycles and modern bicycle difference is bigger.
Real have modern form of bicycle is in 1874's birth. British solution in this year, try to be unique in bicycle is installed on the chain and sprocket, rear wheel rotation to drive the car ahead. But there is still a big front, rear wheel small, doesn't look coordination, unstable. In 1886, Britain's John. K. listrac profit, is a mechanical engineer, from the Angle of mechanical, kinematics devised a new bicycle style, for the bicycle loaded fork and brake and between the same size, to keep balance, and steel pipe made a diamond frame, but also the first to use rubber wheel. Not only improved the fiesta bicycle structure, also restructuring many production bicycle parts of machine tool, for the bicycle with the mass production of the opened wide application prospect, therefore he was later called "bicycle" father of. Listrac and designed by bicycle today the appearance of automobile and bicycle is basically the same.
In 1888, Irish veterinary DengLuoPu, from heal cow flatulence enlighten expansion in the home, he used to water the garden, dozen circle of pipes stick sufficient gas, packed in bicycle wheels, to attend cycling race, incredibly bests, caused great interest. Pneumatic tires is a bicycle history a landmark initiative, it increases the flexibility of bicycle, won't because road gravamen but earthquake, At the same time greatly increased speed, and increases the wheels with pavement of friction. In this way, it is fundamentally changing the bike ride bicycle, and improves the performance of the use function.
Is the same in 1888, coventry of Britain's John. K. listrac and produced the first car modern bicycle -- "safe" bicycle. Its main characteristic is using diamond frame, make body have higher stiffness and strength, rear wheel drive, and by using the chain fork directly grasp the direction.
Early europeans novelties design method
Road bike
The world's first truly practical bike appeared in the early 19th century. 1817, German DE rice in Paris, France invented drop two rounds of the wooden bike. Bicycle when published quickly become at that time Europe person favour of transportation. The 19th century some europeans also conceived out some ideal bicycle figure.
Bicycle inventions in the early stages of the wheels, people think bigger and faster, the speed of the two men riding in a car wheel is almost one high bike.
In the invention of the bicycle stage, some people didn't put the bike before and after the two wheels designed to place, but the two wheels made about the appearance of this kind of bicycle is placed, somewhat similar to a wheelchair.
This is europeans early design of a kind of three-wheel bike. Three-wheel bike balance ability, people are more likely to learn better three-wheel bike riding. Along with the future bicycle technical improvement of three-wheel bike, and gradually developed into a kind of freight transportation.
This is also a paragraph of three-wheel bike, but two power design personnel on the front wheels films, a training wheels on the car back. People are riding the bicycle when ahead still can sit a passenger. This kind of bicycle and modern behind can take person's bicycle design concept is exactly the opposite.
The principle
Bicycle frame, tires, foot chain, brakes, such as 25 components in the basic components are necessary. Among them, the frame is a bicycle skeleton, it suffered and weight of the largest. According to the characteristics of the components can be roughly divided into guiding system and its drive system, braking system:
1, guiding system: by handlebar and fork, front axle, front wheel etc. Parts. Riders can through manipulation handlebar to change driving direction and keep the body in balance.
2, the driver (transmission or walk) system: the pedal, axial, tooth disk, crank, chain, flywheel, rear axle, rear wheel etc. Parts. People in the foot pedal force by riding through the crank, sprockets, chain, flywheel, rear axle component such as transmission, making bicycle ceaselessly.
3, braking system: it consists of brake parts, riders can always manipulation, make driving bike brake mid-fifties, slowing down, to ensure safety.
In addition, in order to safety and beautiful, and from practical, still assembly the headlight, stents unit etc.
composition
Body part
Including frame, front fork, handlebar and saddle and fork close pieces etc, it's bicycle body.
Transmission part
Including pedal, crank, wheel, chain, axial and flywheel etc., by human pedaled pedal, through the above transmission parts drive wheels spin and drove and drove and drove.
Action part
Namely before and after the wheel, including the front axle parts, the spokes, rim (rim), tires, etc.
Safety device
Including brakes (brake), lamp, bell, reflectors, etc. According to the needs, still can increase some accessories, such as stents, racks, insurance fork, fenderboard, pump etc. In addition, equipped with gear mechanisms of sports cars, contests car, mountain bikes are equipped with variable speed controller and chain devices such as before and after the dial.
