Nash Motors Company was an American automobile manufacturer based in Kenosha, Wisconsin, in the United States from 1916 to 1937. From 1937 to 1954, Nash Motors was the automotive division of the Nash-Kelvinator Corporation. Nash production continued from 1954 to 1957 after the creation of American Motors Corporation. Nash pioneered some important innovations; in 1938 they debuted the heating and ventilation system which is still used today, unibody construction in 1941, seat belts in 1950, a US built compact car in 1950, and muscle cars in (1957).〔Foster, Patrick R. ''AMC Cars 1954–1957, an Illustrated History'', p.158. Iconografix 2004. ISBN 1-58388-112-3.〕 == History == Nash Motors was founded in 1916 by former General Motors president Charles W. Nash who acquired the Thomas B. Jeffery Company. Jeffery's best-known automobile was the Rambler whose mass production from a plant in Kenosha, Wisconsin began in 1902. The 1917 Nash Model 671 was the first vehicle produced to bear the name of the new company's founder. Nash enjoyed decades of success by focusing its efforts to build cars "embodying honest worth ... () a price level which held out possibilities of a very wide market." The four-wheel drive Jeffery Quad truck became an important product for Nash. Approximately 11,500 Quads were built between 1913 and 1919. They served to move materiel during World War I under severe conditions. The Quad used Meuhl differentials with half-shafts mounted above the load-bearing dead axles to drive the hubs through hub-reduction gearing.〔(【引用サイトリンク】url=http://www.4wdonline.com/ClassicTrucks/Jeffrey.html )〕 in addition to featuring four-wheel steering. The Quad achieved the reputation of being the best four-wheel drive truck produced in the country. The newly formed Nash Motors became the largest producer of four-wheel drives. By 1918, capacity constraints at Nash meant the Paige-Detroit Motor Car Company began to assemble the Nash Quad under license and Nash patents. Nash became the leading producer of military trucks by the end of World War I. After the war ended, surplus Quads were used as heavy work trucks in fields such as construction and logging. Charles Nash convinced the chief engineer of GM's Oakland Division, Finnish-born Nils Eric Wahlberg, to move to Nash's new company. The first Nash engine introduced in 1917 by Wahlberg had overhead valves. Wahlberg is also credited with helping to design flow-through ventilation that is used today in nearly every motor vehicle. Introduced in 1938, Nash's Weather Eye directed fresh, outside air into the car's fan-boosted, filtered ventilation system, where it was warmed (or cooled), and then removed through rearward placed vents. The process also helped to reduce humidity and equalize the slight pressure differential between the outside and inside of a moving vehicle. Another unique feature of Nash cars was the unequal wheel tracks. The front wheels were set slightly narrower than the rear, thus adding stability and improving cornering. Wahlberg was also an early proponent of wind tunnel testing for vehicles and during World War II worked with Theodore (Ted) Ulrich in the development of Nash's radically styled Airflyte models. Nash's slogan from the late 1920s and 1930s was "Give the customer more than he has paid for" and the cars lived up to it. Innovations included a straight-eight engine with overhead valves, twin spark plugs, and nine crankshaft bearings in 1930. The 1932 Ambassador Eight had synchromesh transmissions and free wheeling, automatic centralized chassis lubrication, a worm-drive rear end, and its suspension was adjustable inside the car. A long-time proponent of automotive safety, Nash was among the early mid- and low-priced cars to offer four-wheel brakes. The Nash was a success among consumers that meant for the company "selling for a long time has been 100% a production problem... month after month all the cars that could be produced were sold before they left the factory floor."〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nash Motors」の詳細全文を読む スポンサード リンク
