33-424: The bus and coach division consists of coaches , public transport buses, chassis modules, second-hand buses and mini & midi buses. The finished products sector is extensive: suspension systems for the automotive industry , production automation systems, heating, cooling and air-technical systems, systems for the oil, gas and petrochemical industry , sunbeds and roof boxes, container handling equipment, systems for

66-419: A body to be added. A few coaches are built with monocoque bodies without a chassis frame. Integrated manufacturers (most of whom also supply chassis) include Autosan , Scania , Fuso , and Alexander Dennis . Major coachwork providers (some of whom can build their own chassis) include Van Hool , Neoplan , Marcopolo , Irizar , MCI , Prevost , Volvo and Designline . In some European countries following

99-514: A combination of castings and sheet-metal stampings". Single-piece carbon fiber bicycle frames are sometimes described as monocoques; however as most use components to form a frame structure (even if molded in a single piece), these are frames not monocoques, and the pedal-cycle industry continues to refer to them as framesets. The P40DC, P42DC and P32ACDM all utilize a monocoque shell. Various rockets have used pressure-stabilized monocoque designs, such as Atlas and Falcon 1 . The Atlas

132-486: A frame. This reduces weight for a given amount of armour. Examples include the German TPz Fuchs and RG-33 . French industrialist and engineer Georges Roy attempted in the 1920s to improve on the bicycle-inspired motorcycle frames of the day, which lacked rigidity. This limited their handling and therefore performance. He applied for a patent in 1926, and at the 1929 Paris Automotive Show unveiled his new motorcycle,

165-406: A fuel tank incorporated into the frame. A monocoque-framed motorcycle was developed by Spanish manufacturer Ossa for the 1967 Grand Prix motorcycle racing season . Although the single-cylinder Ossa had 20 horsepower (15 kW) less than its rivals, it was 45 pounds (20 kg) lighter and its monocoque frame was much stiffer than conventional motorcycle frames , giving it superior agility on

198-413: A minor structural contribution in tension but none in compression and was there for aerodynamic reasons only. By considering the structure as a whole and not just the sum of its parts, monocoque construction integrated the skin and frame into a single load-bearing shell with significant improvements to strength and weight. To make the shell, thin strips of wood were laminated into a three dimensional shape;

231-399: A solid frame. This becomes obvious when internal pressure is lost and the structure collapses. Monocoque tanks can also be cheaper to manufacture than more traditional orthogrids . Blue Origin's upcoming New Glenn launch vehicle will use monocoque construction on its second stage despite the mass penalty in order to reduce the cost of production. This is especially important when the stage

264-550: A specific category/type of RVs . Deriving the name from horse-drawn carriages and stagecoaches that carried passengers, luggage, and mail, modern motor coaches are almost always high-floor buses, with separate luggage hold mounted below the passenger compartment. In contrast to transit buses, motor coaches typically feature forward-facing seating, with no provision for standing. Other accommodations may include onboard restrooms, televisions, and overhead luggage space. Horse-drawn chariots and carriages ("coaches") were used by

297-506: A technique adopted from boat hull construction. One of the earliest examples was the Deperdussin Monocoque racer in 1912, which used a laminated fuselage made up of three layers of glued poplar veneer, which provided both the external skin and the main load-bearing structure. This also produced a smoother surface and reduced drag so effectively that it was able to win most of the races it was entered into. This style of construction

330-497: A tensile stressed skin and a compressive structure made up of longerons and ribs or frames . Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies , which tend to be composites, and inflatable shells or balloon tanks , both of which are pressure stabilised. Early aircraft were constructed using frames, typically of wood or steel tubing, which could then be covered (or skinned ) with fabric such as Irish linen or cotton . The fabric made

363-555: A uniform material. After failed attempts with several large flying boats in which a few components were monocoques, he built the Zeppelin-Lindau V1 to test out a monocoque fuselage. Although it crashed, he learned a lot from its construction. The Dornier-Zeppelin D.I was built in 1918 and although too late for operational service during the war was the first all metal monocoque aircraft to enter production. In parallel to Dornier, Zeppelin also employed Adolf Rohrbach , who built

396-558: Is the president of the company. This article related to bus transport is a stub . You can help Misplaced Pages by expanding it . Coach (vehicle) A coach (also known as a coach bus , motorcoach or parlor coach ) is a type of bus built for longer-distance service, in contrast to transit buses that are typically used within a single metropolitan region. Often used for touring , intercity , and international bus service, coaches are also used for private charter for various purposes. Coaches are also related and fall under

429-459: The Junkers J 1 had appeared as early as 1915, these were not monocoques but added a metal skin to an underlying framework. The first metal monocoques were built by Claudius Dornier , while working for Zeppelin-Lindau. He had to overcome a number of problems, not least was the quality of aluminium alloys strong enough to use as structural materials, which frequently formed layers instead of presenting

462-693: The Zeppelin-Staaken E-4/20 , which when it flew in 1920 became the first multi-engined monocoque airliner, before being destroyed under orders of the Inter-Allied Commission. At the end of WWI, the Inter-Allied Technical Commission published details of the last Zeppelin-Lindau flying boat showing its monocoque construction. In the UK, Oswald Short built a number of experimental aircraft with metal monocoque fuselages starting with

495-427: The 1920 Short Silver Streak in an attempt to convince the air ministry of its superiority over wood. Despite advantages, aluminium alloy monocoques would not become common until the mid 1930s as a result of a number of factors, including design conservatism and production setup costs. Short would eventually prove the merits of the construction method with a series of flying boats, whose metal hulls didn't absorb water as

528-566: The 1958 type certification treaty, coach (that is vehicle of type M2 or M3) type certification is regulated by regulation number 107 from the UNECE. In the U.S., commercial drivers of motorcoaches are regulated by the Federal Motor Carrier Safety Administration (FMCSA). A representative selection of vehicles currently (or recently) in use in different parts of the world. A selection of vehicles in use in different parts of

561-488: The Aero-D One, featuring a composite monocoque chassis that weighed only 12 kg (26 lb). An aluminium monocoque frame was used for the first time on a mass-produced motorcycle from 2000 on Kawasaki's ZX-12R , their flagship production sportbike aimed at being the fastest production motorcycle . It was described by Cycle World in 2000 as a "monocoque backbone ... a single large diameter beam" and "Fabricated from

594-509: The Art-Deco styled 1930 Majestic. Its new type of monocoque body solved the problems he had addressed, and along with better rigidity it did double-duty, as frame and bodywork provided some protection from the elements. Strictly considered, it was more of a semi-monocoque, as it used a box-section, pressed-steel frame with twin side rails riveted together via crossmembers, along with floor pans and rear and front bulkheads. A Piatti light scooter

627-425: The agricultural sector, cigar-making and packaging machines, production systems for optical media and medical systems. The company was formed in 1953 as Metaalindustrie en Constructiewerkplaats P. van der Leegte by Pieter van der Leegte senior, the father of Wim van der Leegte, president and CEO of the company from 1972 until 2016, hence the name VDL. Today, Wim van der Leegte's youngest son, Willem van der Leegte

660-422: The bare essentials such as storage and restrooms. Coaches typically have only a single, narrow door, but some can have two doors, as an increased loading time is acceptable due to infrequent stops. Some characteristics include: Coaches, like buses, may be fully built by integrated manufacturers, or a separate chassis consisting of only an engine, wheels and basic frame may be delivered to a coachwork factory for

693-553: The early years of the 20th century. The first "motor coaches" were purchased by operators of those horse-drawn vehicles in the early 20th century by operators such as Royal Blue Coach Services , who purchased their first charabanc in 1913 and were running 72 coaches by 1926. As they hold passengers for significant periods of time on long journeys, coaches are designed for comfort. They can vary considerably in quality: some higher-specification coaches feature luxury seats, air conditioning , and refreshments, while others may only have

726-550: The first horse-drawn mail coaches in Europe since Roman times in 1650, and as they started in the town of Kocs, the use of these mail coaches gave rise to the term "coach". Stagecoaches (drawn by horses) were used for transport between cities from about 1500 in Great Britain until displaced by the arrival of the railways. One of the earliest motorized vehicles was the charabanc , which was used for short journeys and excursions until

759-463: The racetrack. Ossa won four Grands Prix races with the monocoque bike before their rider died after a crash during the 250 cc event at the 1970 Isle of Man TT , causing the Ossa factory to withdraw from Grand Prix competition. Notable designers such as Eric Offenstadt and Dan Hanebrink created unique monocoque designs for racing in the early 1970s. The F750 event at the 1973 Isle of Man TT races

792-413: The skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining

825-410: The unibody system (also referred to as unitary construction, unitary body–chassis or body–frame integral construction), in which the body of the vehicle, its floor pan, and chassis form a single structure, while the skin adds relatively little strength or stiffness. Some armoured fighting vehicles use a monocoque structure with a body shell built up from armour plates, rather than attaching them to

858-473: The wealthy and powerful where the roads were of a high enough standard from possibly 3000 BC. In Hungary , during the reign of King Matthias Corvinus in the 15th century, the wheelwrights of Kocs began to build a horse-drawn vehicle with steel-spring suspension. This "cart of Kocs" as the Hungarians called it ( Hungarian : kocsi szekér ) soon became popular all over Europe. The imperial post service employed

891-514: The wooden hulls did, greatly improving performance. In the United States, Northrop was a major pioneer, introducing techniques used by his own company and Douglas with the Northrop Alpha . In motor racing, the safety of the driver depends on the car body, which must meet stringent regulations, and only a few cars have been built with monocoque structures. An aluminum alloy monocoque chassis

924-429: The world in the past. Monocoque Monocoque ( / ˈ m ɒ n ə k ɒ k , - k oʊ k / MON -ə-ko(h)k ), also called structural skin , is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word monocoque is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within

957-465: Was first used in the 1962 Lotus 25 Formula 1 race car and McLaren was the first to use carbon-fiber-reinforced polymers to construct the monocoque of the 1981 McLaren MP4/1 . In 1990 the Jaguar XJR-15 became the first production car with a carbon-fiber monocoque. The term monocoque is frequently misapplied to unibody cars. Commercial car bodies are almost never true monocoques but instead use

990-481: Was further developed in Germany by LFG Roland using the patented Wickelrumpf (wrapped hull) form later licensed by them to Pfalz Flugzeugwerke who used it on several fighter aircraft. Each half of the fuselage shell was formed over a male mold using two layers of plywood strips with fabric wrapping between them. The early plywood used was prone to damage from moisture and delamination. While all-metal aircraft such as

1023-426: Was produced in the 1950s using a monocoque hollow shell of sheet-steel pressings welded together, into which the engine and transmission were installed from underneath. The machine could be tipped onto its side, resting on the bolt-on footboards for mechanical access. A monocoque framed scooter was produced by Yamaha from 1960–1962. Model MF-1 was powered by a 50 cc engine with a three-speed transmission and

1056-436: Was very light since a major portion of its structural support was provided by its single-wall steel balloon fuel tanks , which hold their shape while under acceleration by internal pressure. Balloon tanks are not true monocoques but act in the same way as inflatable shells . A balloon tank skin only handles tensile forces while compression is resisted by internal liquid pressure in a way similar to semi-monocoques braced by

1089-505: Was won by Peter Williams on the monocoque-framed John Player Special that he helped to design based on Norton Commando . Honda also experimented with the NR500 , a monocoque Grand Prix racing motorcycle in 1979 . The bike had other innovative features, including an engine with oval shaped cylinders, and eventually succumbed to the problems associated with attempting to develop too many new technologies at once. In 1987 John Britten developed
