The history of the automobile concern Oshkosh begins in the distant 1917, the progenitor of Oshkosh is the equally well-known Four Wheel Drive (FWD) company from Clintonville, Wisconsin. William Besserdich, one of its founders and the owner of several patents, unsuccessfully tried to buy back his share shares from her and was soon forced to leave the company. That same year, Besserdich and Bernard Mosling founded the Wisconsin Duplex Oto Co. in the neighbourhood. The first 1-ton truck, "Old Betsy" 4 × 4, was assembled in May.

In its more than 90-year history, the American company Oshkosh produced mainly powerful all-wheel drive vehicles, distinguished by their simplicity, reliable design and specific appearance. Most Oshkosh vehicles were built to order almost by hand from units of the most prominent specialized firms. The company got its name in honour of the leader of one of the local Indian tribes. The new firm soon moved to Oshkosh, 50 miles south of Clintonville, and was renamed Oshkosh Motor Truck.

Her first car was a bonnet version of the Four Wheel Drive V truck. Next, he received a 4-cylinder LeRoi engine, a 3-speed gearbox and pneumatic tires on all wheels. The second version of the Oshkosh-A in 1918 was equipped with a 72-horsepower 4-cylinder Herschell-Spillman engine with the heated mixture, thermosiphon cooling and an electric starter, a 4-speed Brown-Lipe gearbox, electric horn and headlights, but the main innovation was the first automatic locking centre differential built into the transfer case.

Buyers could not immediately assess the capabilities of a new and rather expensive car: in the first three years, only a little more than 200 units were sold. The further fate of Oshkosh was associated with prolonged and numerous upgrades of its firstborn. In January 1921, the company settled in the workshops of a new enterprise in the same city on Oregon Street, where it remains to this day. There, the production of the 2-ton model "B" began, the carrying capacity increasing to 3.5 tons. The 5-ton "F" model followed it, and from 1924 on, the "H" model began to use 6-cylinder engines.

Such machines were used as tractors, timber trucks, snow ploughs, and unique chassis. The Great Depression contributed to the reorganization of the company, which in 1932 began to produce trucks "FC" and "FB" with a gross weight of up to 20 tons with 6-cylinder engines "Hercules" with a capacity of 102-200 "horses" and gearboxes with many gears of 8 -12. In addition, they were equipped with dump bodies and one of the world's first rotary snowploughs. Produced in 1933, the "TR" was a multi-purpose all-wheel drive and steered chassis with single tires capable of 56 km/h.

Since 1935, the production of the diesel series "G" (models "BG" and "GD") with a carrying capacity of 10-12 tons with "Hercules" or "Cummins" engines with a power of 161-199 hp began. At the same time, the light series "J" with a carrying capacity of 2-3.5 tons went into production, on which a streamlined cab with a solid windshield and a semicircular radiator lining appeared, which became a distinctive feature of Oshkosh products for many years. This was when, for the only time in its history, the company offered simplified versions of the "Express" (Express) of its all-wheel drive vehicles with a 4 × 2 wheel arrangement.

On the eve of the Second World War, the production of a unified series "W" (4 × 4) began, which included eight models from "W100" to "W800" with a carrying capacity of 2-8 tons with Hercules gasoline engines (85-141 hp). In the US Army, they were used as tractors and chassis for mounting rotary snowploughs driven by a second 175-horsepower engine. The 1946 program of the year consisted of several modernized pre-war variants of the "W" series ("W307", "W703", "W906", etc.). Still, the main novelty was the first 3-axle off-road tractor "W1600BD" (6×6) full weighing 27 tons, on which, in addition to the Hercules engines, Cummins and Buda diesel with a capacity of 150 and 180 horsepower, respectively, were used.

A year later, the heavy chassis "W2200" appeared for snow ploughs, the working bodies of which were driven by a hydraulic drive, which made it possible to operate them by one person. The W2200 was followed by a 30-ton W2800 (4×2) mining dump truck with 320-380 horsepower engines and planetary wheel reduction gears. Since 1955, Oshkosh began to produce a series of building chassis "50-50" (4 × 4), in the index of which the formula for the ideal weight distribution of the total weight of the vehicle of 16.3 tons over bridges (50/50%) was encrypted. To do this, the engine was moved forward, and the front wheels were under the cab doors.

Then came the diesel model "45-55" with a gross weight of 18.6 tons, and in 1962 - a similar chassis "U44L" for drilling rigs. Since 1956, the construction chassis "1832" (6x6) has been produced with a gross weight of 24.7 tons on wide-profile single tires. These machines are believed to be the start of series production of new chassis for larger capacity concrete mixers. Oshkosh has become a leader in this area, offering three original multi-axle chassis "C", "F" and "D" with wheel arrangements from 8x4 to 12x10 for several years.

The heaviest 350-horsepower model "D", for mounting a 12-cubic-meter concrete mixer with a gross weight of 34-50 tons, had two front driving and steered axles and four rear axles, of which the last one was lifted with an empty car using a hydraulic lift. In 1960, Oshkosh cars received the well-known spacious steel or aluminium cab with a slightly forward-sloping windshield, a vast rectangular hood, welded fenders with a flat top and a chrome-plated radiator grille with numerous horizontal slots and a protective grille.

In the 1960s, the company began its activities by creating new airfield automotive equipment. Among the models were the U-30 tractor for towing military transport aircraft C5A, the WT2206 rotary snow blower (4 × 4) with 295-325 horsepower engines and automatic transmission, high-speed fire trucks of the MB series ( 4 × 4) and "P4" (6 × 6) with an automatic transmission "Allison". At the same time, the production of the first cabover truck tractor model "3000" for work as part of a 60-ton road train began.

The 1970s saw the creation of an extensive range of trucks, tractors and chassis, many of which are still in production today. They started in 1971 with the only cabover mainline tractor of the "E1223/1244" series (4×2/6×4) in the history of Oshkosh, with engines from different companies with a capacity of 175-325 HP In the United States, he did not receive recognition and his production was transferred to South Africa. More successful was the average bonnet series "R1244 / 1665" with diesel engines "Caterpillar" with a capacity of 280-325 horsepower, which was then assembled in Australia and South Africa.

Since 1974, on the basis of the "F" chassis, the heavy series "J2065 / 2344" (6 × 6 / 8 × 6) has been offered in numerous versions with engines with a capacity of 175-485 horsepower, including options for working in desert areas. In 1975, the production of two more chassis began - a low-frame cabover 350-horsepower "L" and the model "B2344" (6 × 6, 8 × 6, 10 × 6) for a large-capacity concrete mixer with a drum neck and a discharge chute located in front above 1 -but a local cabin of the driver-operator. A powerful diesel engine in a block with a gearbox was located in a single block placed on the rear overhang of the frame.

The development of the fire engine "P4" in 1977 was the largest at that time airfield fire truck "P15" (8 × 8) with a gross weight of about 80 tons with two Detroit Diesel V8 engines with a capacity of 492 horsepower. It served for high-speed delivery of 22,700 litres of fire extinguishing liquids and special equipment to a burning aircraft. Since 1983, Oshkosh has produced an updated "J" series (6×6/8×6), which included a flatbed truck and a semi-trailer tractor with a gross weight of 68 tons, capable of reaching a speed of 80 km / h.

The base tractor "J2065" (8 × 6) was equipped with a Caterpillar diesel engine of 325 horsepower, a manual 9-speed Fuller gearbox (Fuller) or an automatic 4-speed Allison, as well as an average non-driving drawbridge. The lightest chassis, "MTTO" with a gross weight of 4.5 tons for snow plows and cabover tractor "K2444" (4 × 4) had both steerable axles. The sharp turn of the Oshkosh company to the serial production of military vehicles took place in 1976, when it won a competition for the manufacture of a large batch of 450-horsepower M-911 truck tractors for transporting tanks.

Having bought a license from the Lockheed military-industrial concern since 1981 Oshkosh has been producing the Dragon Wagon 8 × 8 army multi-purpose truck with an articulated frame. It later formed the basis of the so-called "heavy highly mobile tactical truck" HEMTT (8×8) with a rigid frame. Since 1990, Oshkosh has been mass-producing the largest tank transporter in the United States - a huge M-1070 (8 × 8) truck tractor with a 500-horsepower diesel engine and a high 6-seater "blunt-nosed" cab. The latest novelty was a 5-axle army tractor-transporter "M-1075" (10 × 10) with a 3-axle trailer, equipped with a system for quick loading of interchangeable bodies or cargo on pallets (PLS).

With a gross weight of 62.4 tons, such a road train develops a speed of 91 km / h. Military orders allowed the company to safely survive the crises and withstand increased competition. In the mid-90s, new generations of "F" series models with updated cladding ("F2146/2365" and "FF115"), as well as multifunctional bonneted cars "P2526/2546" (4 × 4 / 6 × 6) appeared in its program. With engines with a capacity of 260-470 horsepower. The company began production of new airfield fire engines "T1500" (4 × 4) and "T3OOO" (6 × 6) with engines with a capacity of 585 horsepower, capable of developing a speed of 105 km / h with a gross weight of 45.2-66.6 tons.

There were also low-frame chassis "NK" and "NL" (4 × 2/6 × 4) for garbage trucks and construction "S2146" (6 × 6, 8 × 6, 10 × 6.12 × 6) with a gross weight of 36 tons from 335 -powerful rear-mounted diesel engine and a wide 1-seater aluminium cab. Today, thanks to military orders, Oshkosh remains the world's only major and most well-known manufacturer of large-sized specialized vehicles. Its position became even more stable in 1995 with the signing of a cooperation agreement with the Freightliner company, which subsequently allowed it to absorb the fire engine manufacturer Pierce and the McNeilus company, which produces garbage trucks. In 1997, Oshkosh's sales reached $675 million.
