Csepel D-344
The Csepel D-344 is a medium size, 3-tonne, 4×4 off-road lorry, made by Hungarian manufacturer Csepel Autógyár, from 1961 to 1975. It was first presented to the public on the Leipzig Trade Fair in early 1963. The Hungarian People's Army purchased huge quantities of the D-344, and eventually used it as their standard lorry. It proved to be robust and reliable. Description The Csepel D-344 uses a welded ladder frame, and has two permanently driven, leaf spring, leaf-sprung live axles. The front axle has single wheels, whereas the rear axle has twin wheels. All wheels are of the size 9.00–20.00 in. In its standard configuration, the D-344 has a ground clearance of 270 mm and a fording depth of 800 mm. The D-344 has a pneumatic braking system with drum brakes on all wheels. The ramp angle is 35° on the front axle, and 25° on the rear axle; the maximum gradeability is 44%. The Csepel D-344 is powered by a Csepel D-414H naturally aspirated, 5.5-litre, precombus ...

Csepel Autógyár
Csepel was a Hungarian manufacturer of trucks for industrial use. History In 1944 the Steyr 380 truck was designed in Austria, licensing Csepel lorries and engines. Production of the MÁVAG and the RÁBA lorries stopped after nationalization in 1946. In 1947 Hungary bought the licence for the Steyr 380 lorry, D413 and D613 engines from the USSR. At this time, the Soviets occupied the Eastern part of Austria. In 1949 an automobile factory was established in the NIK (Nehéz Ipari Központ—en: Heavy Industry Center) at the earlier Dunai Repülőgépgyár—en: Danube Aircraft Factory place at Szigethalom. The first Csepel (NIK) engine was ready on 7 November. The first director of the factory was Ferencné Bíró. She was a mechanical engineer and had studied in Moscow, sister-in-law of Mátyás Rákosi. The first 3 Csepel D-350 were ready on 3 April 1950. The D-350 and B-350 types were produced between 1950 and 1958. The B-130 4x4 rover pickup lorry began production in ...

Live Axle
A beam axle, rigid axle or solid axle is a dependent suspension design in which a set of wheels is connected laterally by a single beam or shaft. Beam axles were once commonly used at the rear wheels of a vehicle, but historically they have also been used as front axles in four-wheel-drive vehicles. In most automobiles, beam axles have been replaced with front and rear independent suspensions. Implementation With a beam axle the camber angle between the wheels is the same no matter where it is in the travel of the suspension. A beam axle's fore & aft location is constrained by either: trailing arms, semi-trailing arms, radius rods, or leaf springs. The lateral location can be constrained by a Panhard rod, a Scott Russell linkage or a Watt's linkage, or some other arrangement, most commonly by the leaf springs. Shock absorbers and either leaf springs, coil springs, or air bags are used to control vertical movement. The Twist-beam rear suspension is a similar suspension desig ...

Differential (mechanical Device)
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. Functional description The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears (these are not strictly necessary; see spur-gear differential): Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears (which drive the axle half-shafts) will rotate at different speeds relative to the ring gear (one faster, one slower) by, say, 2 full turns each (4 full turns relative to each other), resulting in the left wheel mak ...

Transfer Case
A transfer case is a part of the drivetrain of four-wheel-drive, all-wheel-drive, and other multiple powered axle vehicles. The transfer case transfers power from the transmission to the front and rear axles by means of drive shafts. It also synchronizes the difference between the rotation of the front and rear wheels, and may contain one or more sets of low range gears for off-road use. Functions * The transfer case receives power from the transmission and sends it to both the front and rear axles, or just one (usually the rear.) This can be done with gears, hydraulics, or chain drive. On some vehicles, such as four-wheel-drive trucks or vehicles intended for off-road use, this feature is controlled by the driver. The driver can put the transfer case into either "two-wheel-drive" or "four-wheel-drive" mode. This is sometimes accomplished by means of a shifter, similar to that in a manual transmission. On some vehicles, this may be electronically operated by a switch inste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the ...

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precombustion Chamber
Indirect injection in an internal combustion engine is fuel injection where fuel is not directly injected into the combustion chamber. Gasoline engines equipped with indirect injection systems, wherein a fuel injector delivers the fuel at some point before the intake valve, have mostly fallen out of favor to direct injection. However, certain manufacturers such as Volkswagen, Toyota and Ford have developed a 'dual injection' system, combining direct injectors with port (indirect) injectors, combining the benefits of both types of fuel injection. Direct injection allows the fuel to be precisely metered into the combustion chamber under high pressure which can lead to greater power, fuel efficiency. The issue with direct injection is that it typically leads to greater amounts of particulate matter and with the fuel no longer contacting the intake valves, carbon can accumulate on the intake valves over time. Adding indirect injection keeps fuel spraying on the intake valves, reducing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drum Brake
A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term ''drum brake'' usually means a brake in which shoes press on the inner surface of the drum. When shoes press on the outside of the drum, it is usually called a '' 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 Maybach in 1900, although the principle was only later patented in 1902 by Louis Renault. He used woven asbestos lining for the drum brake lining, as no alternative dissipated heat like the asbestos lining, though Maybach had used a less sophisticated drum brake. In the first drum brakes, levers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Spring
A leaf spring is a simple form of spring commonly used for the 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 which 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 this reason, some manufacturers have ...

Lorry
A truck or lorry is a motor vehicle designed to transport cargo, carry specialized payloads, or perform other utilitarian work. Trucks vary greatly in size, power, and configuration, but the vast majority feature body-on-frame construction, with a cabin that is independent of the payload portion of the vehicle. Smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful and may be configured to be mounted with specialized equipment, such as in the case of refuse trucks, fire trucks, concrete mixers, and suction excavators. In American English, a commercial vehicle without a trailer or other articulation is formally a "straight truck" while one designed specifically to pull a trailer is not a truck but a "Tractor unit, tractor". The majority of trucks currently in use are still powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in the US, Canada, and Mexico. The market-share of ...

Csepel D-344 01
Csepel (german: Tschepele) is the 21st district and a neighbourhood in Budapest, Hungary. Csepel officially became part of Budapest on 1 January 1950. Location Csepel is located at the northern end of Csepel Island in the Danube, and covers one-tenth of the island's area. Being on an island, it is the only complete district of Budapest which is neither in Pest nor in Buda. On the western side it is bordered by the Danube, while the Ráckevei-Duna (Ráckeve's Danube) runs along the eastern side. The twenty-first district is bordered by the settlements of Szigetszentmiklós and Lakihegy to the south. It has approximately 85,000 inhabitants. Transportation Csepel is most easily accessed from central Budapest by the H7 Csepel HÉV, a high capacity suburban railway. In addition, it is served by BKK buses 138, 35, 36, 148, 151, and 179. Bridges connect Csepel to southern parts of Pest, Ferencváros and Pesterzsébet, and a ferry links Csepel to Soroksár. By car Csepel ...

Hungarian People's Army
The Hungarian People's Army ( hu, Magyar Néphadsereg) or the HPA was the military of the Hungarian People's Republic and the armed branch of the Hungarian Socialist Workers' Party from 1951 to 1990. It only saw combat in a foreign country once during its existence, which was assisting the Soviet Union in crushing the Prague Spring. It maintained close ties to the Warsaw Pact along with other Eastern Bloc countries. It dissolved in 1989 and retained its current form through the Hungarian Defence Force. History Early years Soviet influence over the Hungarian armed forces began to rapidly increase starting in November 1948, "..when hundreds of Soviet military "advisers" were assigned to the Hungarian army from the top all the way down to the regimental level. Although theoretically acting only as advisers, they influenced all important decisions. Beginning in December 1948, thousands of Hungarians began attending Soviet military and political academies to gain technical expertis ...
