Saxomat
Saxomat was a type of automatic clutch available as an option on Fiat 1800, Lancia Flaminia, Saab 93, Borgward Isabella, Goliath/Hansa 1100, Auto Union 1000, Ford Taunus, Trabant, other than some models from BMW, Opel, Steyr-Puch, NSU, Glas, Wartburg and Volkswagen. Opel sold it as Olymat; Trabant and Wartburg named the system Hycomat. The Hydrak, used in some Mercedes-Benz vehicles between 1957 and 1961, was a similar system with a hydrodynamic torque converter in place of the Saxomat's centrifugal clutch, this H.T.C. system was standard on NSU Ro 80 and was optional on the Porsche 911 (Sportomatic). The system also reappeared in the 1990s as Saab Sensonic, but Saab shelved that technology since 1998. Hyundai also reintroduced similar concept as the Intelligent Manual Transmission (iMT) in 2020 with the latest generation Hyundai i20. Cars with a Saxomat clutch did not have a clutch pedal. The Saxomat consisted of two independent systems: the centrifugal clutch, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Goliath 1100
The Goliath 1100 and later the Hansa 1100 is a small automobile that was manufactured from 1957 until 1961 by the Bremen based Goliath-Werke Borgward & Co, a subsidiary of Borgward. A two-door saloon and a three-door ''kombi'' (estate) version were available from launch and a two-door coupe was introduced a year later. For 1959, the Goliath name was discontinued and the car was rebadged as the Hansa 1100, recalling Borgward’s prewar model of the same name. The Goliath 1100 replaced the Goliath GP900 and apart from a completely new engine, little had changed. In place of the GP 700’s two-stroke engine, the 1100 featured a water-cooled boxer motor, an engine format taken up by Subaru several years after the demise of the Goliath brand. Goliath and Borgward The Goliath business had been established in 1928 by the entrepreneurial engineer Carl Borgward in partnership with Wilhelm Tecklenburg. The plant had been bombed to destruction during the war, but during the 1950s produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Clutch
A centrifugal clutch is an automatic clutch that uses centrifugal force to operate. The output shaft is disengaged at low rotational speed and engages more as speed increases. It is often used in mopeds, underbones, lawn mowers, go-karts, chainsaws, mini bikes, and some paramotors and boats to keep the engine from stalling when the output shaft is slowed or stopped abruptly, and to remove load when starting and idling. It has been superseded for automobile applications by the fluid coupling and automated manual transmissions. Operation The input of the clutch is connected to the engine crankshaft while the output may drive a shaft, chain, or belt. As engine revolutions per minute increase, weighted arms in the clutch swing outward and force the clutch to engage. The most common types have friction pads or shoes radially mounted that engage the inside of the rim of a housing. On the center shaft, there is an assorted number of extension springs, which connect to a clutch shoe. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lancia Flaminia
The Lancia Flaminia (Tipo 813/823/824/826) is a luxury car produced by Italian automaker Lancia from 1957 until 1970. It was Lancia's flagship model at that time, replacing the Aurelia. It was available throughout its lifetime as saloon, coupé and cabriolet. The Flaminia coupé and convertible were coachbuilt cars with bodies from several prestigious Italian coachbuilders. Four "presidential" stretched limousine Flaminias were produced by Pininfarina for use on state occasions. There were 12,633 Flaminias sold over 13 years. Coupés outsold the four-door saloon, an unusual occurrence otherwise seen at the time only in American compact and midsize models whose coupé versions were standard factory models that cost the same or less than the sedan, while the Flaminia coupés' coachbuilt bodies made them considerably more expensive than the limousine-like Berlina. Name The Flaminia was named after the Via Flaminia, the road leading from Rome to Ariminum (Rimini). This respected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab 93
The Saab 93 (pronounced ''ninety-three'') is the second production automobile that was manufactured by Saab. Styled by Sixten Sason, it was first presented on December 1, 1955. The 93 was powered by a longitudinally-mounted three-cylinder 748 cc Saab two-stroke engine giving 33 hp (25 kW). The gearbox had three gears, the first unsynchronised. In order to overcome the problems of oil starvation on overrun (engine braking) for the two-stroke engine, a freewheel device was fitted. In 1957, two-point seatbelts were introduced as an option. The 93 was the first Saab to be exported from Sweden, with most exports going to the United States. A Saxomat clutch and a cabrio coach (large cloth sunroof) were available as options. On September 2, 1957, the 93B was introduced. The original two-piece windshield was also replaced with a one-piece windshield. In 1957, Erik Carlsson finished 1st in the Finland Rally in a Saab 93; in 1959, he was 1st in the Swedish Rally, also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Transmission
A semi-automatic transmission is a "theoretical" multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input would be required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and planetary gearsets. Names for specific types of semi-automatic transmissions include ''clutchless manual'', ''auto-manual'', ''auto-clutch manual'', and ''paddle-shift'' transmissions. These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servo, while still requiring the driver to manually shift gears.

NSU Motorenwerke AG
NSU Motorenwerke AG, or NSU, was a German manufacturer of automobiles, motorcycles and pedal cycles, founded in 1873. Acquired by Volkswagen Group in 1969, VW merged NSU with Auto Union, creating Audi NSU Auto Union AG, ultimately Audi. The name NSU originated as an abbreviation of "Neckarsulm", the city where NSU was located. History Origin NSU originated as the "Mechanische Werkstätte zur Herstellung von Strickmaschinen", a knitting machine manufacturer established in 1873 by Christian Schmidt, a technically astute entrepreneur, in the town of Riedlingen on the Danube. The business relocated in 1880 to Neckarsulm. There followed a period of rapid growth and in 1886, the company began to produce bicycles, the first of them a 'high wheeler' or 'Penny-farthing' branded as the "Germania". By 1892, bicycle manufacturing had completely replaced knitting machine production. At about this time, the name NSU appeared as a brand name. The first NSU motorcycle appeared in 1901, ...

Manifold Vacuum
Manifold vacuum, or engine vacuum in an internal combustion engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere. Manifold vacuum is an effect of a piston's movement on the induction stroke and the choked flow through a throttle in the intake manifold of an engine. It is a measure of the amount of restriction of airflow through the engine, and hence of the unused power capacity in the engine. In some engines, the manifold vacuum is also used as an auxiliary power source to drive engine accessories and for the crankcase ventilation system. Manifold vacuums should not be confused with Venturi vacuums, which are an effect exploited in carburetors to establish a pressure difference roughly proportional to mass airflow and to maintain a somewhat constant air/fuel ratio. It is also used in light airplanes to provide airflow for pneumatic gyroscopic instruments. Overview The rate of airflow through an internal combustion engine is an ...

Centrifugal Governor
A centrifugal governor is a specific type of governor with a feedback system that controls the speed of an engine by regulating the flow of fuel or working fluid, so as to maintain a near-constant speed. It uses the principle of proportional control. Centrifugal governors, also known as "centrifugal regulators" and "fly-ball governors", were invented by Christiaan Huygens and used to regulate the distance and pressure between millstones in windmills in the 17th century. In 1788, James Watt adapted one to control his steam engine where it regulates the admission of steam into the cylinder(s), a development that proved so important he is sometimes called the inventor. Centrifugal governors' widest use was on steam engines during the Steam Age in the 19th century. They are also found on stationary internal combustion engines and variously fueled turbines, and in some modern striking clocks. A simple governor does not maintain an exact speed but a speed range, since under increasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Force
In Newtonian mechanics, the centrifugal force is an inertial force (also called a "fictitious" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It is directed away from an axis which is parallel to the axis of rotation and passing through the coordinate system's origin. If the axis of rotation passes through the coordinate system's origin, the centrifugal force is directed radially outwards from that axis. The magnitude of centrifugal force ''F'' on an object of mass ''m'' at the distance ''r'' from the origin of a frame of reference rotating with angular velocity is: F = m\omega^2 r The concept of centrifugal force can be applied in rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves, when they are analyzed in a rotating coordinate system. Confusingly, the term has sometimes also been used for the reactive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotational Speed
Rotational frequency (also known as rotational speed or rate of rotation) of an object rotating around an axis is the frequency of rotation of the object. Its unit is revolution per minute (rpm), cycle per second (cps), etc. The symbol for rotational frequency is \nu (the Greek lowercase letter nu). Tangential speed ''v'', rotational frequency \nu, and radial distance ''r'', are related by the following equation: :v = 2\pi r\nu :v = r\omega An algebraic rearrangement of this equation allows us to solve for rotational frequency: :\nu = v/2\pi r :\omega = v/r Thus, the tangential speed will be directly proportional to ''r'' when all parts of a system simultaneously have the same ''ω'', as for a wheel, disk, or rigid wand. The direct proportionality of ''v'' to ''r'' is not valid for the planets, because the planets have different rotational frequencies. Rotational frequency can measure, for example, how fast a motor is running. ''Rotational speed'' is sometimes used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
