The bicycle is the most successful human inventions of a human machine, is composed of many simple machines
Complex machinery。
In 1790, there were French, his love for brains。 One day, he was walking a street in Paris, because the world over the previous rain, the way a lot of rain plot, it is good to go。
Suddenly, a carriage came straight from behind, the road is fairly narrow and very wide carriage, Xifulake fortunate not to hide to avoid being hit by a car, or been splashed all over a mud and rain。
Others see, feel sorry for him, but also angry and Zhi Ma, want to cry carriage stopped, unreasonable representations。 Xifulake has murmured: "Do not cry, do not cry, let them go。
" Carriage gone, and he just stood roadside。 He was thinking: Road so narrow, so many pedestrians, why can not the coach what the structure to facilitate some changes? Should be cut off half of the carriage along the four wheels, two wheels into a before and after the 。
。。 。。。 he such a thought, home on hands-on design。 After repeated tests, the first aircraft in 1791 to travel by "Trojan wheel" car made out。
Zhe Liang wooden cart with two wheels around the middle attached beam, a bench top security, like a toy-like。 As the car has not drive chain, by the rider pedal force in their legs, the car can move forward slowly, but also without steering the car, only go straight, do not turn and go riding for a while on the tired sweaty 。
The emergence of new stuff just is not always so perfect。 Xifulake not discouraged, he continued to try to improve。
Unfortunately, the long illness he died。
1816, in Germany there is to see in the woods His names is delaxis, his daily-east of this one from the forest, wandering the West's another piece of wood, year after year。
He thought: If the person sitting in the car, the stop-go, anywhere, not very handsome it? Delaisse began making wooden wheel, made almost look like Xifulake。
However, adding a front wheel on the handlebar control the direction of child, to change the way forward。 But cycling is still to use two feet, about what step to push off the ground, to push the car roll forward。
When dries out test riding time along the way were many people laughing。 Still, he loves his creation of this "lovely pony cubs。
" Wandering in the cycle when one dries over an open carriage, the driver laughed at his car, he said slowly, so he and the driver said: "Believe it or not my car faster than your horse" So the two of them play the bet。
Distance from the village of West-east to a back and forth, results dries faster than the driver a whole more than one hour。
In 1840, England's blacksmith McMillan, and got a run-down "pony cute cubs。" He installed on the rear axle crank, and then crank and connecting rod to connect the front of the pedal, and both front and rear wheels with iron, large front and rear small。
When the rider stepped fixed pedal, the car will be up on their own campaign, ran forward。 Thus, it makes the rider's feet off the ground really, to walk, alternating stepping move into the wheel rolling, speed greatly improved。
1842, Macmillan ride this car, ran 20 kilometers a day, because they do not care, cycling too fast, hit the road a little girl, it was the police to seize, and fines。
The charges of "brutal ride。"
In 1861, France Michaud and his son, originally a carriage repair Carpenter job, they can be installed in front of the pedal plate rotation; car saddle rack above the front wheel, so unless the bike's technology, especially sophisticated, or instability on the grasping handlebars, fell off from the car。
They Zheliang two-wheelers as a "bicycle" of James, and in 1867 at the Paris Expo exhibition, the audience an eye-opener。
In 1869, Renault UK after seeing the bike in France, that car is too heavy, and began pondering how to light a number of bike do。
He used to tightening wire spoke wheel rim as; the same time, the use made of thin steel bars to the frame, the car's front wheel larger smaller rear wheel。
Thereby reducing some of its own weight bicycle。 Starting from Xifulake until Renault, who made 5 types of bike with a larger difference between the modern bicycle。
Truly modern form of bike is born in 1874。 British Roson in the year, the ingenuity in the bicycle chain and sprockets on the uploading, with rear-wheel rotation to drive the car forward。
But still the big front wheel, rear wheel small, do not seem as coordinated and unstable。
In 1886, the United Kingdom John。
K。 Stahly, a mechanical engineer, from the mechanics, kinematics point of view to design a new bike style bicycle fitted with a fork and brakes, front and rear wheel size the same in order to maintain balance and control into diamond-shaped steel frame for the first time using a rubber wheel。
Stahly not only improves the bike's structure, but also restructured a number of machines used in production of bicycle parts for bike's mass production application of interest to promote the prospects opened up wide, and he was later known as the "father of a bike。
" Stahly bike designed with today's models look basically the same as a bicycle。
In 1888, Ireland's veterinary Dunlop, from the expansion in the treatment of bovine Stomach inspiration, he used to water the garden around the house in a rubber tube into a round stick, play full of gas, mounted on bicycle wheels, to participate in Cycling competition, actually among the best, has aroused great interest。
Pneumatic tire is a landmark in the history of bicycle development initiative, it increases the flexibility of the bicycle, not because of road roughness and vibration; the same time greatly improve the speed and reduce friction with the road wheels。
Thus, fundamentally changed the bike's riding performance, improved bicycle use function。
Also 1888, Coventry City, John。
K。 Stahly produced the first modern bike --- a "safety" bicycle。 Its main characteristic is using diamond-shaped frame, so the body has a higher stiffness and strength, the rear wheels with a chain drive, and take direction directly through the front fork。
自行车是最成功的人类发明，人类机，是由许多简单机械组成
复杂的机器。
1790年，有法国人，他对大脑的爱。有一天，他走在巴黎街头，因为世界上比前雨，路上的雨水积了很多，这是好去。突然，一辆马车从后面开门见山，道路很窄，很宽的运输，Xifulake幸运不要隐瞒，以免被车撞了，或者被溅了泥，下雨。
别人看到，觉得对不起他，但也生气，支马，想哭马车停了下来，不合理的陈述。 Xifulake已喃喃地说：“不要哭，不要哭，让他们走。”马车走了，他只是站在路边。他在想：路这么窄，这么多的行人，为什么不能教练什么结构，以便利一些变化？应切断沿四个轮子的马车的一半，成为一个前后两个轮子的。
。。 。。。他这么想着，手上的家庭设计。经过反复试验，在1791年第一架飞机旅行的“木马轮”开出的车。这辆木头车围在中间有两个连接梁，一台高级安全像玩具似的，车轮。当汽车还没有驱动器骑手链，在他们的腿力量踏板，车子可以前进缓慢，但也没有方向盘的车，只能走直线，不转了，去一出汗就累了，而骑。
在刚刚出现的新东西并不总是那么完美。 Xifulake并不气馁，他继续设法改善。不幸的是，长期患病，他死了。
1816年，在德国有在树林里看到他的名字是delaxis，他每天，这从林一东，西徘徊的另一块木头，年复一年。
他想：如果人在车内坐着，走走停停，任何地方，不是很漂亮吗？ Delaisse开始制作木轮，使几乎像Xifulake。然而，增加对儿童的车把控制方向，方式的转变，提出了前轮。但自行车仍然是使用两只脚，什么步骤，蹬地，推动车滚滚向前。当骑乘时间进行测试干了沿途许多人都在笑。
尽管如此，他热爱他的这一创作“可爱的小马崽。”在游荡时，一个周期通过开放马车干燥后，司机在他的车笑了，他缓缓地说，他和司机说：“信不信由你，我的车比你的马”，所以他们二人玩赌。距离西，东港村一个来回，结果干燥速度超过了一个多小时司机整个更多。
1840年，英格兰的铁匠麦克米伦，并得到了破旧的“可爱的小马崽。”他安装在后轴曲柄，然后曲柄连杆连接踏板的前面，正面和铁，大前，后方的小后轮。当骑手分级的固定踏板，该车将在自己的宣传活动起来，向前跑。因此，它使离地面骑手的脚真的，走路，交替进入滚轮，步进移动速度大大提高。
1842年，麦克米伦坐这车，跑了20公里的一天，因为他们不关心，骑车太快，上路了一个小女孩，这是警方抓住，并罚款。指控的“残酷的旅程。”
1861年，法国的米肖父子，原本是马车修理匠的工作，它们可以安装在脚踏板转动前面;车以上前轮鞍架，因此除非自行车的技术，特别是复杂的，或在不稳定抓车把，从车上摔了下来。
他们这辆两为“自行车”的詹姆斯轮车，并在巴黎博览会展出，观众大开眼界1867年。
1869年，英国在看到雷诺在法国的自行车，那车太重，开始琢磨怎么点的自行车数量做。他用收紧线辐轮辋的，同一个时间，使薄钢筋使用框架，汽车的前轮大后轮小。
从而减少自身重量自行车一些。从Xifulake起至雷诺，谁取得与现代之间的较大差别，自行车5自行车类型。
真正的现代形式的自行车是出生于1874年。英国人罗松在这一年里，在自行车链条和链轮上载独创性，与后轮驱动车旋转前进。
但仍是前轮大，后轮小，看起来不够协调，不稳定。
1886年，英国约翰。光斯塔利，机械工程师，从力学，运动学角度来设计一个新的自行车款式的自行车用叉子和制动器，前后轮大小相同的安装，以保持成菱形钢架平衡和控制首次使用橡胶轮子。
斯塔利不仅提高了自行车的结构，而且还调整了在自行车零件生产自行车的群众利益，促进发展前景的生产应用程序中使用的机器数量开辟了广泛的，他后来被称为“自行车之父”。斯塔利自行车与今天的模式设计的外观基本相同自行车。
1888年，爱尔兰的兽医邓洛普，从在牛胃吸入治疗扩张，他用的水成圆棍围绕在一个橡胶管家的花园，发挥中气十足，架在自行车轮子，参加自行车竞争实际上名列前茅，引起了极大的兴趣。
充气轮胎是在自行车发展史上具有里程碑意义的倡议，它增加了自行车的灵活性，不要因为路面平整度及振动，同时大大提高了速度，降低车轮与路面摩擦。因此，从根本上改变了自行车的骑行性能，提高自行车的使用功能。
此外1888年，考文垂市，约翰。
光斯塔利生产出第一台现代自行车---“安全”自行车。其主要特点是采用菱形车架，所以身体具有较高的刚度和强度，用链条驱动后轮，并通过直接的前叉方向。
