VK 4501 (P)
The VK 45.01 (P), also informally known as Tiger (P) or Porsche Tiger, was a gasoline-electric drive heavy tank prototype designed by Porsche in Germany. Losing to its Henschel competitor on trials, it was not selected for mass production and the Henschel design was produced as the Tiger I. Most of the already produced chassis were rebuilt as Elefant tank destroyers. Development On 26 May 1941, Henschel and Porsche were asked to submit designs for a 45-ton heavy tank capable of mounting the high velocity 8.8 cm Kwk 36 L/56 gun which was derived from the German 88 mm Flak 37 antiaircraft gun. Both the Henschel and Porsche tanks were to be fitted with the same turret supplied by Krupp. The Porsche company worked on updating the VK 30.01 (P) medium tank, Porsche's medium tank prototype, and adapted parts used on it for the new tank. The new Porsche tank, designated the VK 45.01 (P) was to be powered by twin V-10 air cooled Porsche Type 101 gasoline engines which were moun ...

Elefant
The ''Elefant'' (German for "elephant") was a heavy tank destroyer used by German Wehrmacht Panzerjäger during World War II. Ninety-one units were built in 1943 under the name Ferdinand, after its designer Ferdinand Porsche, using VK 45.01 (P) tank hulls produced for the Tiger I tank design abandoned in favour of a Henschel design. In January to April 1944, ''Ferdinands'' received modifications and upgrades. They were renamed ''Elefant'' in May 1944. The official German designation was ''Panzerjäger Tiger'' (P)Not to be confused with either the ''Panzerkampfwagen VI Tiger Ausf. H'' or ''Ausf. E'' versions of the Tiger I, or the ''Panzerkampfwagen Tiger Ausf. B'' (Tiger II) and the ordnance inventory designation was ''Sd.Kfz.'' 184. Development history Porsche GmbH had manufactured about 100 chassis for their unsuccessful proposal for the Tiger tank, the " Porsche Tiger", in the Nibelungenwerk factory in Sankt Valentin, Austria. Both the successful Henschel proposal and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jagdpanzer
''Jagdpanzer'' (JgPz) is the name given in German to a heavily-armoured, tracked tank destroyer, although it may also be used for other kinds of self-propelled guns. Literally translated from German, ''Jagdpanzer'' is "hunting tank". It typically refers to anti-tank variants of existing tank chassis with a well-armoured casemate fixed superstructure, mounting an anti-tank gun with limited traverse in the front, and classed by the western Allies of World War II as a tank destroyer. History The ''Jagdpanzer'' designs followed on from the more lightly armoured ''Panzerjäger'' ("tank hunter") designs, which took an anti-tank gun and mounted it on top of a tank chassis with supplementary armour fitted around the gun crew. However, the armour had an open rear and top, almost never providing the crew with full protection from the elements. In addition, much experience was gained from the Sturmgeschütz series of assault guns for infantry support, which already used heavily armour ...

MG 34
The MG 34 (shortened from German: ''Maschinengewehr 34'', or "machine gun 34") is a German recoil-operated air-cooled general-purpose machine gun, first tested in 1929, introduced in 1934, and issued to units in 1936. It introduced an entirely new concept in automatic firepower – the ''Einheitsmaschinengewehr'' (Universal machine gun) – and is generally considered the world's first general-purpose machine gun (GPMG). Both the MG 34 and MG 42 were erroneously nicknamed "Spandau" by Allied troops, a carryover from the World War I nickname for the MG 08, which was produced at the Spandau Arsenal. The versatile MG 34 was chambered for the full-power 7.92×57mm Mauser rifle cartridge, and was arguably the most advanced machine gun in the world at the time of its deployment. The MG 34 was envisaged and well developed to provide portable light and medium machine gun infantry cover, anti-aircraft coverage, and even sniping ability. Its combination of exceptional mobility – bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drive Wheel
A drive wheel is a wheel of a motor vehicle that transmits force, transforming torque into tractive force from the tires to the road, causing the vehicle to move. The powertrain delivers enough torque to the wheel to overcome stationary forces, resulting in the vehicle moving forwards or backwards. A two-wheel drive vehicle has two driven wheels, typically both at the front or back, while a four-wheel drive has four. A steering wheel is a wheel that turns to change the direction of a vehicle. A trailer wheel is one that is neither a drive wheel, nor a steer wheel. Front-wheel drive vehicles typically have the rear wheels as trailer wheels. Drive wheel configurations Front-wheel drive Front-wheel drive (FWD) vehicles' engines drive the front wheels. Using the front wheels for delivery of power as well as steering allows the driving force to act in the same direction as the wheel is pointing. This layout is commonly used in modern passenger cars. A rare example of front ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission (mechanics)
Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term ''transmission'' properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. In the United States the term is sometimes used in casual speech to refer more specifically to the gearbox alone, and detailed usage differs. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process. Transmissions are also used on pedal bicycles, fixed machines, and where different rotational speeds and torques are adapted. Often, a transmission has multiple gear ratios (or simply "gears") with the ability to switch between them as the speed varies. This switching may be done manually (by the operator) or automatically (by a control unit). Directional (forward and reverse) control may also be provided. Single-ratio transmissions also exist, which simply ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powertrain
A drivetrain (also frequently spelled as drive train or sometimes drive-train) is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. This excludes the engine or motor that generates the power. In marine applications, the drive shaft will drive a propeller, thruster, or waterjet rather than a drive axle, while the actual engine might be similar to an automotive engine. Other machinery, equipment and vehicles may also use a drivetrain to deliver power from the engine(s) to the driven components. In contrast, the powertrain is considered to include both the engine and/or motor(s) as well as the drivetrain. Function The function of the drivetrain is to couple the engine that produces the power to the driving wheels that use this mechanical power to rotate the axle. This connection involves physically linking the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the ...

Electric Generator
In electricity generation, a generator is a device that converts motive power ( mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electro ...

Ferdinand Porsche
Ferdinand Porsche (3 September 1875 – 30 January 1951) was an Austrian-German automotive engineer and founder of the Porsche AG. He is best known for creating the first gasoline–electric hybrid vehicle (Lohner–Porsche), the Volkswagen Beetle, the Auto Union racing car, the Mercedes-Benz SS/SSK, several other important developments and Porsche automobiles. An important contributor to the German war effort during World War II, Porsche was involved in the production of advanced tanks such as the VK 4501 (P), the Elefant (initially called "Ferdinand") self-propelled gun, and the Panzer VIII Maus super-heavy tank, as well as other weapon systems, including the V-1 flying bomb. Porsche was a member of the Nazi Party and an officer of the Schutzstaffel (SS). He was a recipient of the German National Prize for Art and Science, the SS-Ehrenring and the War Merit Cross. Porsche was inducted into the International Motorsports Hall of Fame in 1996 and was named the Car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. ...
