GM Roto Hydramatic Transmission
Roto Hydramatic (sometimes spelled Roto Hydra-Matic or Roto-Hydramatic) was an automatic transmission built by General Motors and used in some Oldsmobile, Pontiac and Holden models between 1961 and 1965. It was based on the earlier, four-speed Hydramatic, but was more compact, providing only three forward speeds plus a small 8" fluid coupling with a stator inside of the fluid coupling (a type of torque converter, only integral with the transmission rather than being an independent unit). Oldsmobile, one of the companies that used this transmission in some of its cars, called the fluid couplings stator the "Accel-A-Rotor." The lightweight, aluminum-cased transmission was sometimes nicknamed the "Slim Jim." HydraMatic Division calls the Roto a four-range, three-gear HydraMatic. It counts the stator multiplication at 3.50:1 as a first gear, and when road speed and the two coupling halves’ speed match, it counts the same gear with fluid now passing straight through the stator ...

Automatic Transmission
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may also colloquially called a " slushbox" or simply a "torque converter", although the latter term c ...

Oldsmobile Starfire
The Oldsmobile Starfire is an automobile nameplate used by Oldsmobile, produced in three non-contiguous generations beginning in 1954. The Starfire nameplate made its debut as a convertible concept car in 1953 followed with the 1954–1956 Ninety-Eight series convertibles that shared a "halo status" with the Buick Skylark and Cadillac Eldorado. For 1957 only, all Ninety-Eight series models were named "98 Starfire ". Oldsmobile during this time period was one of the most popular brands selling, and the company saw an opportunity to benefit from the Space Race of the 1960s. The "rocket" terminology was already a benefit with their Rocket V8. After a two-year hiatus the Starfire name returned for 1961 as separate model, offered in a single convertible body style. Intended to compete in the growing personal luxury car market, from 1961 to 1965 the Starfire Convertible was the highest-priced model offered by Oldsmobile. While it shared most of its sheet metal with other full-si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Drive
Automatic Drive was the trade name for Studebaker Corporation's first automatic transmission, designed in conjunction with Borg-Warner's Detroit Gear division. Studebaker was one of two independent American auto manufacturers to invest in development and tooling for automatic transmissions, the other being Packard with its Ultramatic product. Automatic Drive, which combined a three-speed planetary gearset and a lock-up torque converter, debuted in early 1950 as a $201 option on all Studebaker models. Ford, which was without an automatic transmission in 1950, approached Studebaker about buying Automatic Drive units. Studebaker's management refused and thereby lost out on what could have been significant "plus" business. By 1955, Studebaker was forced to abandon the Automatic Drive because of high production costs, replacing it with a less-expensive Borg Warner unit based on Ford's Ford-O-Matic, which Studebaker called Flight-O-Matic. Borg-Warner continued to build Studebaker's Aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock-up Clutch
A clutch is a mechanical device that engages and disengages power Transmission (mechanics), 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 (mechanics), 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 shaft ...

Ultramatic
Ultramatic was the trademarked name of the Packard Motor Car Company's automatic transmission introduced in 1949 and produced until 1954, at Packard's Detroit, Michigan East Grand Boulevard factory. It was produced thereafter from late 1954, thru 1956 at the new Packard "Utica" Utica, Michigan facility. 1935-1948: Development Packard's Ultramatic transmission was the creation of the company's chief engineer Forest McFarland and his engineering team. The magnitude of this accomplishment is illustrated by the fact that it was the only automatic transmission developed and produced solely by an independent automaker, with no outside help. Devices like the Ultramatic were being tested and designed by Packard from 1935 on, but none satisfied the perfectionist engineer. The Ultramatic's development was halted, as was all automotive work during World War II, but resumed in earnest during 1946. After World War II, Packard's range had contracted to variants of the mid-priced Clipper line. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flexplate
A flexplate (or flex plate) is a metal disk that connects the output from an engine to the input of a torque converter in a car equipped with an automatic transmission. It takes the place of the flywheel found in a conventional manual transmission setup. The name refers to the ability of the disk to flex across its main axis bending side to side to take up motion in the torque converter as rotational speeds change. Flexplates are generally much thinner and lighter than flywheels due to the smooth coupling action of the torque converter and the elimination of the clutch surface. Like flywheels, flexplates normally handle coupling to the starter motor, via teeth cut along the outer edge of the plate. These teeth give the flexplate a gear-like appearance, in spite of this being a secondary function. Flexplates come in many forms, but are usually either stamped steel (common on road cars), a two-piece billet (common on race cars) or a one-piece billet (common high-performance drag racer ...

Flywheel
A flywheel is a mechanical device which uses the conservation of angular momentum to store rotational energy; a form of kinetic energy proportional to the product of its moment of inertia and the square of its rotational speed. In particular, assuming the flywheel's moment of inertia is constant (i.e., a flywheel with fixed mass and second moment of area revolving about some fixed axis) then the stored (rotational) energy is directly associated with the square of its rotational speed. Since a flywheel serves to store mechanical energy for later use, it is natural to consider it as a kinetic energy analogue of an electrical inductor. Once suitably abstracted, this shared principle of energy storage is described in the generalized concept of an accumulator. As with other types of accumulators, a flywheel inherently smooths sufficiently small deviations in the power output of a system, thereby effectively playing the role of a low-pass filter with respect to the mechanical velocity ...

Bell Housing
Bell housing or bellhousing is a colloquial/slang term for the portion of the transmission that covers the flywheel and the clutch or torque converter of the transmission on vehicles powered by internal combustion engines. This housing is bolted to the engine block and derives its name from the bell-like shape that its internal components necessitate. The starter motor is usually mounted here, and engages with a ring gear on the flywheel. On the opposite end to the engine is usually bolted to the gearbox. The use of different bellhousings on a transmission allows the same transmission to be used on multiple engines in multiple applications. However, on some transmissions, the bellhousing is a nonremovable part of the transmission case. This is particularly true with front wheel drive transmissions, which are much shorter than conventional rear wheel drive transmissions.

Pontiac Bonneville
The Pontiac Bonneville is an automobile built by Pontiac (automobile), Pontiac from 1957 until 2005. Bonnevilles were full-size car, full-sized, with the exception of a brief period of mid-size car, mid-size between 1982 and 1986. The brand was introduced as a limited production performance convertible during the 1957 model year. The Bonneville (known as the Parisienne in Canada until 1981), and its platform partner, the Pontiac Grand Ville, Grand Ville, are some of the largest Pontiacs ever built; in station wagon body styles they reached just over long, and at and more were also some of the heaviest cars produced at the time. The name was taken from the Bonneville Salt Flats in Utah, the site of much early auto racing and most of the world's land speed record runs, which was named in turn after U.S. Army officer Benjamin Bonneville. Luxury Trim Package and Concept Car The Bonneville name first appeared in 1954 on a pair of bubble-topped GM Motorama concept cars called the ...

Pontiac Star Chief
The Pontiac Star Chief is an automobile model which was manufactured by Pontiac between 1954 and 1966. It was Pontiac's top trim package on the Pontiac Chieftain, with later generations built on longer wheelbases, and serving as the foundation platform for the Pontiac Bonneville. The car was easily identified by its chrome star trim along its sides, a feature all Star Chiefs were equipped with. __TOC__ First generation (1954) Between 1954 and 1957, the Star Chief was Pontiac's prestige model and was based on the Pontiac Chieftain. In 1954, Pontiac also introduced air conditioning with all the components under the hood, a first for the price range. Seat belts were added as options in 1956. The Star Chief was available in Deluxe and pricier Custom trim, with the top trim level hardtop called the Catalina. Prior to the introduction of the Star Chief, all Pontiacs had shared the modest wheelbase of the Chevrolet since the beginning of Pontiac. The introduction of this new premier ...

Pontiac Grand Prix
The Grand Prix is a line of automobiles produced by the Pontiac Division of General Motors from 1962 until 2002 for coupes and 1989–2008 for sedans. First introduced as a full-size performance coupe for the 1962 model year, the model varied repeatedly in size, luxury, and performance during its production. The Grand Prix was the most expensive coupe Pontiac offered until the 1970s, when the Bonneville Brougham and the Firebird Trans Am became more exclusive. Among the changes were positioning in the personal luxury car market segment and mid-size car offering from the second generation to the fifth generation for the sedan and from the second generation to the sixth generation from the coupe. The Grand Prix, which is French for "grand prize", returned to a full-size car from the sixth generation to the seventh generation for the sedan, positioned below the larger Bonneville in Pontiac's model lineup. First generation (1962–1964) 1962 The Grand Prix was an all-new m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
