Lancia 1Z
The Lancia 1Z was a light military truck produced by Italian manufacturer Lancia between 1912 and 1916. From a mechanical standpoint, it was closely related to the 1913 35 HP Theta passenger car. It was Lancia's first military vehicle. Development and service history At the outbreak of the Italo-Turkish War of 1911, the Royal Italian Army, whose motorisation had only begun a few years before, was chiefly equipped with Fiat 15 trucks. After a positive experience on the field, the army handed out additional procurements contracts of trucks for tactical and logistical use, to both Fiat and other manufacturers. One of them was Lancia, which developed the 1Z and began deliveries in 1912, in time for the vehicle to see war service on the harsh terrains of Libya. Production and army use continued into the First World War. In 1916, Ansaldo and Lancia jointly built an armored car on the 1Z chassis, named '' Automitragliatrice Lancia Ansaldo 1Z''. These were the Royal Italian Army ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truck
A truck or lorry is a motor vehicle designed to transport freight, 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". The majority of trucks currently in use are powered by diesel engines, although small- to medium-size trucks with gasoline engines exist in North America. Electrically powered trucks are more popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Anti-aircraft Weapon
An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft warfare, anti-aircraft capability. Specific weapon systems used include machine guns, autocannons, larger guns, or surface-to-air missiles, and some mount both guns and longer-ranged missiles (e.g. the Pantsir missile system). Platforms used include both trucks and heavier combat vehicles such as armoured personnel carriers and tanks, which add protection from aircraft, artillery, and small arms fire for front line deployment. Anti-aircraft guns are usually mounted in a quickly-traversing gun turret, turret with a high rate of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. In addition, most anti-aircraft guns can be used in a direct-fire role against surface targets to great effect. Today, surface-to-air missiles (generally mounte ... [...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] |
Solid Axle
Solid is a state of matter where molecules are closely packed and can not slide past each other. Solids resist compression, expansion, or external forces that would alter its shape, with the degree to which they are resisted dependent upon the specific material under consideration. Solids also always possess the least amount of kinetic energy per atom/molecule relative to other phases or, equivalently stated, solids are formed when matter in the liquid / gas phase is cooled below a certain temperature. This temperature is called the melting point of that substance and is an intrinsic property, i.e. independent of how much of the matter there is. All matter in solids can be arranged on a microscopic scale under certain conditions. Solids are characterized by structural rigidity and resistance to applied external forces and pressure. Unlike liquids, solids do not flow to take on the shape of their container, nor do they expand to fill the entire available volume like a gas. Much ...

Ladder Frame
A vehicle frame, also historically known as its ''chassis'', is the main supporting structure of a motor vehicle to which all other components are attached, comparable to the skeleton of an organism. Until the 1930s, virtually every car had a structural frame separate from its body, known as ''body-on-frame'' construction. Both mass production of completed vehicles by a manufacturer using this method, epitomized by the Ford Model T, and supply of rolling chassis to coachbuilders for both mass production (as by Fisher Body in the United States) and to smaller firms (such as Hooper (coachbuilder), Hooper) for bespoke bodies and interiors was practiced. By the 1960s, unibody construction in passenger cars had become common, and the trend towards building unibody passenger cars continued over the ensuing decades. Nearly all trucks, buses, and most Pickup truck, pickups continue to use a separate frame as their chassis. Functions The main functions of a frame in a motor vehicle ...

Monobloc Head
''Monobloc'' refers to a component that is made in one block or casting. A monobloc engine or en bloc engine is an internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single integral unit, rather than being assembled later. This has the advantages of improving mechanical stiffness, and improving the reliability of the sealing between them. ''Monobloc'' techniques date back to the beginnings of the internal combustion engine. Use of this term has changed over time, usually to address the most pressing mechanical problem affecting the engines of its day. There have been three distinct uses of the technique: * #Cylinder head, Cylinder head and cylinder * #Cylinder block, Cylinder block * Cylinder block and #Crankcase, crankcase In most cases, any use of the term describes single-unit construction that is opposed to the more common contemporary practice. Where the monobloc technique ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Side Valve
A flathead engine, also known as a sidevalve engine''American Rodder'', 6/94, pp.45 & 93. or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally by automobile manufacturers from the late 1890s until the mid-1960s but were replaced by more efficient overhead valve and overhead camshaft engines. They are currently experiencing a revival in low-revving aero-engines such as the D-Motor. The side-valve design The valve gear comprises a camshaft sited low in the cylinder block which operates the poppet valves via tappets and short pushrods (or sometimes with no pushrods at all). The flathead system obviates the need for further valvetrain components such as lengthy pushrods, rocker arms, overhead valves or overhead camshafts. The sidevalves are typically adjacent, sited on one side of the cylinder(s), though s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse Artillery
Horse artillery was a type of light, fast-moving, and fast-firing field artillery that consisted of light cannons or howitzers attached to light but sturdy two-wheeled carriages called caissons or limbers, with the individual crewmen riding on horses. This was in contrast to other forms of field artillery which may also be horse-drawn but were heavier and whose gunners either marched on foot or were transported seated on the gun carriage, wagons or limbers. Horse artillery units provided highly mobile fire support especially to cavalry units, and existed in armies in Europe, the Americas, and Asia, from the early 17th to the mid-20th century. Tactics Once in position, horse artillery crews were trained to quickly dismount, deploy or unlimber their guns (detach them from their caissons), then rapidly fire grapeshot, shells or round shot at the enemy. They could then just as rapidly limber-up (reattach the guns to the caissons), remount, and be ready to move to a new position, ...

Cannone Da 75/27 Modello 11
The Cannone da 75/27 modello 11 was a French-designed field gun produced in Italy prior to World War I. It was introduced in 1912, designed by Joseph-Albert Deport. It was taken into service by Italy for use with its Alpine and cavalry troops going into World War I, and was built there in large numbers. The gun was designed with two notable features. It was the first artillery piece to introduce the split trail, as well as the last to utilize its novel dual-recoil system. The former became a very popular feature on artillery pieces through to the modern day. The later, while functional, did not get repeated. The dual-recoil system consisted of a small tubular recoil under the barrel which in turn traveled in a traditional rectangular cradle. This lessened heat transfer from the gun barrel to the recoil mechanism effectively, but was not necessary for the added complexity. Some guns had two crew seats on the front of the gun shield. The gun was used by the Italian army throughout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Artillery
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and self-propelled rocket artillery. They are high-mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar (weapon), mortar, or some form of rocket (weapon), rocket/missile launcher. They are usually used for long-range indirect-fire, indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and tank destroyers, which were typically well-armoured vehicles often based upon the chassis of a tank. In lieu of the standard tank's general-purpose tank gun, main gun that fired both high-explosive and anti-tank ammunition, direct-fire vehicles had specialized roles, with assault guns providing close fire-supp ...

Field Gun
A field gun is a field artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march, that when in combat could be moved about the battlefield in response to changing circumstances (field artillery), as opposed to guns installed in a fort (Royal Garrison Artillery, garrison artillery or coastal artillery), or to siege cannons and mortar (weapon), mortars which are too large to be moved quickly, and would be used only in a prolonged siege. Perhaps the most famous use of the field gun in terms of advanced tactics was Napoleon Bonaparte's use of very large wheels on the guns that allowed them to be moved quickly even during a battle. By moving the guns from point to point during a battle, enemy formations could be broken up to be handled by the infantry or cavalry wherever they were massing, dramatically increasing the overall effectiveness of the attack. World War I As the evolution of artillery continued, almost all guns of any siz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
