Hydramatic
Hydramatic (also known as Hydra-Matic) is an automatic transmission developed by General Motors Corporation's Oldsmobile Division, the ''Hydramatic'' was the first mass-produced fully automatic transmission developed for passenger automobile use. The Hydra-Matic transmission was introduced by Oldsmobile in 1939 model, one year before Cadillac accepted it for their 1940 model year. History During the 1930s, automakers sought to reduce or eliminate the need to shift gears. At the time, synchronized gear shifting was still a novelty (and confined to higher gears in most cases), and shifting a manual gearbox required more effort than most drivers cared to exert. The exception here was Cadillac's break-through synchromesh fully synchronized manual transmission, designed by Cadillac engineer Earl A. Thompson and introduced in the autumn of 1928. Cadillac, under Thompson, began working on a 'shiftless' transmission in 1932, and a new department within Cadillac Engineering was creat ...

Dynaflow
Dynaflow was the trademarked name for a type of automatic transmission developed and built by General Motors Buick Motor Division from late 1947 to mid-1963. The Dynaflow, which was introduced for the 1948 model year only as an option on Roadmaster models, was based on similar principles as those applied for the Torqmatic transmission used in the M18 Hellcat tank destroyer (built in Buick's Flint Assembly plant) and M26 Pershing tank during World War II, namely a multi-element torque converter and manually selected intermediate gears. It was also used in the 1951 Le Sabre concept car. History Original version The Dynaflow was an automatic transmission used in various forms in Buick cars by the General Motors Corporation from 1947 until 1963. The transmission initially used a five-element torque converter, with two impellers and two stators, as well as a planetary gearset that provided two forward speeds plus reverse. In normal driving, Dynaflow started in high gear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldsmobile Series 70
The Oldsmobile Series 70 is a full-size midrange automobile produced by Oldsmobile between the 1939 and 1950 model years. Oldsmobiles of this time period were in an unusual "middle" position in GM's hierarchy of automobile brands. Chevrolet and Pontiac were the budget priced models, while Buick and Cadillac were the luxury brands. GM would share their "A" body platforms between Chevrolet, Pontiac, and "B" body on Oldsmobile and Buick, while leaving Cadillac on the senior "C" platform. Oldsmobiles were then branded as "luxury level" Chevrolets and Pontiacs, while Oldsmobiles using the "B" platform were "budget priced" Buicks and Cadillacs. Competitors from Ford's Mercury and Chrysler's DeSoto brands would give customers a choice to have Oldsmobile levels of luxury, while not paying as much for a comparable Oldsmobile. GM in later years would discontinue the Series 70 and the budget Oldsmobile Series 60, and introduce the Oldsmobile 88 to push Oldsmobile upmarket, giving Chevr ...

Pontiac (automobile)
Pontiac, formally the Pontiac Motor Division of General Motors, was an American automobile brand owned, manufactured, and commercialized by General Motors. It was introduced in 1926 as a General Motors companion make program, companion make for GM's more expensive line of Oakland Motor Car Company, Oakland automobiles. Pontiac quickly overtook Oakland in popularity and supplanted its parent entirely by 1933, establishing its position as one of GM's dominant divisions. Sold in the United States, Canada, and Mexico by GM, Pontiac came to represent affordable, practical transportation emphasizing performance. The division’s name stems from the Odawa chieftain Pontiac (Odawa leader), Pontiac, who led an Pontiac's War, indigenous uprising from 1763 until 1766 around Detroit, Michigan. In the hierarchy of GM's five divisions, it slotted above Chevrolet but below Oldsmobile, Buick, and Cadillac. Starting with the 1959 models, marketing was focused on selling the lifestyle that the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldsmobile Series 60
The Series 60 "Special" is a full-size car made by Oldsmobile from the 1939 through the 1948 model years. It was their entry-level model using the GM "A" body platform, giving Oldsmobile an entry-level product with more standard features that would be optional on Chevrolet and Pontiac vehicles using the same platform. Initially, the engine size used was the company's flat head 6 cylinder, while senior models would use the flat head 8 cylinder. For marketing purposes, the Oldsmobile Series 60, or the Oldsmobile 66, took advantage of the national highway U.S. Route 66 established in 1926. It was with this generation that all GM vehicles experienced increased width dimensions to accommodate three passengers on the front bench seat and an additional three passengers on rear bench seat installed vehicles. This was accomplished with the deletion of running board thereby adding additional room inside the passenger compartment and upgrading the floor mounted gearshift to a steering column ...

Automatic Transmission
An automatic transmission (AT) or automatic gearbox is a multi-speed transmission (mechanics), transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first true automatic transmission. The first mass-produced automatic transmission is the General Motors ''Hydramatic'' two-speed hydraulic automatic, which was introduced in 1939. Automatic transmissions are especially prevalent in vehicular drivetrains, particularly those subject to intense mechanical acceleration and frequent idle/transient operating conditions; commonly commercial/passenger/utility vehicles, such as buses and waste collection vehicles. Prevalence Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive t ...

Fluid Coupling
A fluid coupling or hydraulic coupling is a hydrodynamics, hydrodynamic or 'hydrokinetic' device used to transmit rotating mechanical power.Fluid coupling ''encyclopedia2.thefreedictionary.com'' It has been used in automobile Transmission (mechanics), transmissions as an alternative to a mechanical clutch. It also has widespread application in marine and industrial machine drives, where variable speed operation and controlled start-up without Shock (mechanics), shock loading of the power transmission system is essential. Hydrokinetic drives, such as this, should be distinguished from hydrostatic drives, such as hydraulic pump and hydraulic motor, motor combinations.

M5 Stuart
The M3 Stuart/light tank M3, was a US light tank of World War II, first entered service in the British Army in early 1941 and saw action in the North African campaign in July 1941. Later an improved version of the tank entered service as the M5 in 1942 to be supplied to British and other allied Commonwealth forces under lend-lease prior to the entry of the United States into the war. The British service name "Stuart" came from the U.S. Civil War Confederate general J. E. B. Stuart and was used for both the M3 and the derivative M5 light tank. Unofficially, they were also often called "Honeys" by the British, because of their smooth ride. In U.S. use, the tanks were officially known as "light tank M3" and "light tank M5". Stuarts were first used in combat in the North African campaign; about 170 were used by the British forces in Operation Crusader (18 November – 30 December 1941). Stuarts were the first American-crewed tanks in World War II to engage the enemy in tan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
