TAM Pionir
The Praga RN () was a medium-sized truck manufactured by Praga from 1933. The vehicle was powered by a six-cylinder petrol engine. From 1934, the diesel-powered version Praga RND () was also manufactured. The trucks were manufactured for nearly three decades and became one of the most widely used freight wagons in Czechoslovakia, the chassis being used for buses and fire engines as well as for military uses. RN production ended in 1953 and RND in 1955, although production continued in Yugoslavia until 1962. In total, around 40,000 Praga RN and RND were produced, including about 3,700 buses, as well as 18,300 RN license built in Yugoslavia. History Praga launched the RN in 1933 as a traditional medium-weight truck with rigid axles and a sheet metal cab wrapped around a wooden skeleton and mounted on a ladder frame. Initial production was 94 vehicles, half in 1934. In 1937, a larger carburettor was introduced that increased power from to over and payload from to , along with a ...

Czechoslovak Army
The Czechoslovak Army (Czech and Slovak: ''Československá armáda'') was the name of the armed forces of Czechoslovakia. It was established in 1918 following Czechoslovakia's declaration of independence from Austria-Hungary. History In the first week after the declaration of independence, the Army of the new Czechoslovak state consisted mainly of Czech and Slovak units of the Austro-Hungarian Army, and later incorporated members of the Czechoslovak Legion from Italy and France. that fought alongside the Entente during World War I. The Czechoslovak Army took part in the brief Polish-Czechoslovak War, in which Czechoslovakia annexed the Trans-Olza region from Poland. It also fought a border war with Hungary for control and borders of Slovakia. The Army was modeled after the Austro-Hungarian Army, with the influence of a French military mission. Its initial officers were both former Austro-Hungarian and Legion officers who decided to stay in the active service. The first c ...

Kingdom Of Yugoslavia
The Kingdom of Yugoslavia was a country in Southeast Europe, Southeast and Central Europe that existed from 1918 until 1941. From 1918 to 1929, it was officially called the Kingdom of Serbs, Croats, and Slovenes, but the term "Yugoslavia" () has been its colloquial name as early as 1922 due to its origins. "Kraljevina Jugoslavija! Novi naziv naše države. No, mi smo itak med seboj vedno dejali Jugoslavija, četudi je bilo na vseh uradnih listih Kraljevina Srbov, Hrvatov in Slovencev. In tudi drugi narodi, kakor Nemci in Francozi, so pisali že prej v svojih listih mnogo o Jugoslaviji. 3. oktobra, ko je kralj Aleksander podpisal "Zakon o nazivu in razdelitvi kraljevine na upravna območja", pa je bil naslov kraljevine Srbov, Hrvatov in Slovencev za vedno izbrisan." (Naš rod ("Our Generation", a monthly Slovene language periodical), Ljubljana 1929/30, št. 1, str. 22, letnik I.) The official name of the state was changed to "Kingdom of Yugoslavia" by King Alexander I of Yugosla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Spring
A leaf spring is a simple form of spring (device), spring commonly used for suspension (vehicle), suspension in wheeled vehicles. Originally called a ''laminated'' or ''carriage spring'', and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates that are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drum Brake
A drum brake is a brake that uses friction caused by a set of Brake shoe, shoes or Brake pad, pads that press outward against a rotating bowl-shaped part called a brake drum. The term ''drum brake'' usually means a brake in which shoes press on the Brake lining, inner surface of the drum. When shoes press on the outside of the drum, it is usually called a ''Railway brake, clasp brake''. Where the drum is pinched between two shoes, similar to a conventional disc brake, it is sometimes called a ''pinch drum brake'', though such brakes are relatively rare. A related type called a band brake uses a flexible belt or "band" wrapping around the outside of a drum. History The modern automobile drum brake was first used in a car made by Wilhelm Maybach, Maybach in 1900, although the principle was only later patented in 1902 by Louis Renault (industrialist), Louis Renault. He used woven asbestos lining for the drum brake lining, as no alternative material dissipated heat more effectivel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Joint
A universal joint (also called a universal coupling or U-joint) is a joint or coupling connecting rigid shafts whose axes are inclined to each other. It is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant-velocity joint. U-joints are also sometimes called by various eponymous names, as follows: * Cardan joint, after Gerolamo Cardano, a polymath of the 16th century who contributed to knowledge of various clever mechanisms, including gimbals * Hooke joint or Hooke's joint, after Robert Hooke, a polymath of the 17th century who contributed to knowledge of various clever mechanisms * Spicer joint, after Clarence W. Spicer and the Spicer Manufacturing Company, who manufactured U joints * Hardy Spicer joint, after the Hardy Spicer brand, a successor to the Spicer brand History The main concept of the universal joi ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace, and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission. Common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic ...

Overhead Valve Engine
An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above the combustion chamber. This contrasts with flathead (or "sidevalve") engines, where the valves were located below the combustion chamber in the engine block. Although an overhead camshaft (OHC) engine also has overhead valves, the common usage of the term "overhead valve engine" is limited to engines where the camshaft is located in the engine block. In these traditional OHV engines, the motion of the camshaft is transferred using pushrods (hence the term "pushrod engine") and rocker arms to operate the valves at the top of the engine. However, some designs have the camshaft in the cylinder head but still sit below or alongside the valves (the Ford CVH and Opel CIH are good examples), so they can essentially be considered overhead valve designs. Some early intake-over-exhaust engines used a hybrid design combining eleme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carburetor
A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle or with a Pitot tube in the main metering circuit, though various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires the greater precision and pressure of fuel injection. Etymology The term ''carburetor'' is derived from the verb ''carburet'', which means "to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
