Georg Lankensperger
Georg Lankensperger (also: Lankensberger), (31 March 1779 – 11 July 1847) was a German wheelwright who invented the steering mechanism that is today known as Ackermann steering geometry. He patented the invention in Germany, but his agent Rudolph Ackermann filed for the patent in the U.K. Early life Lankensperger was born in Marktl in the district of Oberbayern in Germany. Career Lankensperger invented his steering mechanism in 1816 as Hofwagner (''Head waggoner'') in Munich, to allow the front wheels of a carriage to individually follow the natural arc of its turning circle, rather than skidding and slipping when they are forced to each share a common arc with the conventional pivoted axle. It continues to be used in horse-drawn carriages and passenger cars to this day..Veröffentlicht: ''„Wöchentlicher Anzeiger für Kunst- und Gewerbfleiß im Königreich Baiern“, No. 24, 15.

Wheelwright
A wheelwright is a craftsman who builds or repairs wooden wheels. The word is the combination of "wheel" and the word "wright", (which comes from the Old English word "''wryhta''", meaning a worker or shaper of wood) as in shipwright and arkwright. This occupational name became the English surname ''Wright''. It also appears in surnames like ''Cartwright'' and ''Wainwright''. It corresponds with skilful metal workers being called ''Smith.'' These tradesmen made wheels for carts (cartwheels), wagons (wains), traps and coaches and the belt drives of steam powered machinery. They also made the wheels, and often the frames, for spinning wheels for home use. First constructing the hub (called the nave), the spokes and the rim segments called felloes, (pronounced fell low), and assembling them all into a unit working from the center of the wheel outwards. Most wheels were made from wood, but other materials have been used, such as bone and horn, for decorative or other purposes. ...

Ackermann Steering Geometry
The Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii. It was invented by the German carriage builder Georg Lankensperger in Munich in 1817, then patented by his agent in England, Rudolph Ackermann (1764–1834) in 1818 for horse-drawn carriages. Erasmus Darwin may have a prior claim as the inventor dating from 1758. He devised his steering system because he was injured when a carriage tipped over. Advantages The intention of Ackermann geometry is to avoid the need for tires to slip sideways when following the path around a curve. The geometrical solution to this is for all wheels to have their axles arranged as radii of circles with a common centre point. As the rear wheels are fixed, this centre point must be on a line extended from the rear axle. Intersecting the axes of the front wheels on th ...

Rudolph Ackermann
Rudolph Ackermann (20 April 1764 in Schneeberg, Electorate of Saxony – 30 March 1834 in Finchley, London) was an Anglo-German bookseller, inventor, lithographer, publisher and businessman. Biography He attended the Latin school in Stollberg, but his wish to study at the university was made impossible by lack of financial means, and he therefore became a saddler like his father. He worked as a saddler and coach-builder in different German cities, moved from Dresden to Basel and Paris, and then, 23 years old, settled in London. He established himself in Long Acre, the centre of coach-making in London and close to the market at Covent Garden. His extraordinary business instinct, as well as his flair for design and talent for self-promotion, won him the £200 contract to design the ceremonial coach for the Lord Chancellor of Ireland, John FitzGibbon, 1st Earl of Clare. After this he designed ''The Royal Sailor'', an 8-wheel omnibus that ran between Charing Cross, Greenwi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oberbayern
Upper Bavaria (german: Oberbayern, ; ) is one of the seven administrative districts of Bavaria, Germany. Geography Upper Bavaria is located in the southern portion of Bavaria, and is centered on the city of Munich, both state capital and seat of the district government. Because of this, it is by far the most populous administrative division in Bavaria. It is subdivided into four planning regions (''Planungsverband''): Ingolstadt, Munich, Bayerisches Oberland (Bavarian Highland), and Südostoberbayern (South East Upper Bavaria). The name 'Upper Bavaria' refers to the relative position on the Danube and its tributaries: downstream, Upper Bavaria is followed by Lower Bavaria, then Upper Austria, and subsequently Lower Austria.

19th-century German Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
