Ford Model T
The Ford Model T is an automobile that was produced by the Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first mass-affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual handcrafting. The savings from mass production allowed the price to decline from $780 in 1910 to $290 in 1924. It was mainly designed by three engineers, Joseph A. Galamb, Eugene Farkas, and Childe Harold Wills. The Model T was colloquially known as the "Tin Lizzie".
The Ford Model T was named the most influential car of the 20th century in the 1999 Car of the Century competition, ahead of the BMC Mini, Citroën DS, and Volkswagen Beetle. Ford's Model T was successful not only because it provided inexpensive transportation on a massive scale, but also because the car signified innovation for the rising middle class and became a powerful symbol of the United States' age of modernization. With over 15 million sold, it was the most sold car in history before being surpassed by the Volkswagen Beetle in 1972.
Introduction
Early automobiles, which were produced from the 1880s, were mostly scarce, expensive, and often unreliable. Being the first reliable, easily maintained, mass-market motorized transportation turned the Model T into a great success: Within a few days after release, 15,000 orders were placed.The first production Model T was built on August 12, 1908, and left the factory on September 27, 1908, at the Ford Piquette Avenue Plant in Detroit, Michigan. On May 26, 1927, Henry Ford watched the 15 millionth Model T Ford roll off the assembly line at his factory in Highland Park, Michigan.
Henry Ford conceived a series of cars between the founding of the company in 1903 and the introduction of the Model T. Ford named his first car the Model A and proceeded through the alphabet up through the Model T. Twenty models in all, not all of which went into production. The production model immediately before the Model T was the Model S, an upgraded version of the company's largest success to that point, the Model N. The follow-up to the Model T was another Ford Model A, rather than the "Model U". The company publicity said this was because the new car was such a departure from the old that Ford wanted to start all over again with the letter A.
The Model T was Ford's first automobile mass-produced on moving assembly lines with completely interchangeable parts, marketed to the middle class. Henry Ford said of the vehicle:
I will build a motor car for the great multitude. It will be large enough for the family, but small enough for the individual to run and care for. It will be constructed of the best materials, by the best men to be hired, after the simplest designs that modern engineering can devise. But it will be so low in price that no man making a good salary will be unable to own one – and enjoy with his family the blessing of hours of pleasure in God's great open spaces.
Although Ransom E. Olds developed the assembly line for the first mass-produced automobile, the Oldsmobile Curved Dash, having begun in 1901, Ford and his engineers developed tremendous advances in the efficiency of the system over the life of the Model T.
Characteristics and design
The Model T was designed by Childe Harold Wills, and Hungarian immigrants Joseph A. Galamb and Eugene Farkas. Henry Love, C. J. Smith, Gus Degner and Peter E. Martin were also part of the team, as were Galamb's fellow Hungarian immigrants Gyula Hartenberger and Károly Balogh. Henry Ford supervised the designers himself. Production of the Model T began in the third quarter of 1908. Collectors today sometimes classify Model Ts by build years and refer to these as "model years", thus labeling the first Model Ts as 1909 models. This is a retroactive classification scheme; the concept of model years as understood today did not exist at the time. Even though [|design revisions occurred] during the car's two decades of production, the company gave no particular name to any of the revised designs; all of them were called simply "Model T".Engine
The Model T has a front-mounted inline four-cylinder engine, producing, for a top speed of. According to Ford Motor Company, the Model T had fuel economy of. The engine was designed to run on gasoline, although it was able to run on kerosene or ethanol, although the decreasing cost of gasoline and the later introduction of Prohibition made ethanol an impractical fuel for most users. The engines of the first 2,447 units were cooled with water pumps; the engines of unit 2,448 and onward, with a few exceptions prior to around unit 2,500, were cooled by thermosiphon action.The ignition system used in the Model T was an unusual one, with a low-voltage magneto incorporated in the flywheel, supplying alternating current to trembler coils to drive the spark plugs. This was closer to that used for stationary gas engines than the expensive high-voltage ignition magnetos that were used on some other cars. This ignition also made the Model T more flexible as to the quality or type of fuel it used. The system did not need a starting battery, since proper hand-cranking would generate enough current for starting. Electric lighting powered by the magneto was adopted in 1915, replacing acetylene gas flame lamp and oil lamps, but electric starting was not offered until 1919.
The Model T engine was produced for replacement needs as well as stationary and marine applications until 1941, well after production of the Model T ended.
The Fordson Model F tractor engine, that was designed about a decade later, was very similar to, but larger than, the Model T engine.
Transmission and drive train
The Model T is a rear-wheel drive vehicle. Its transmission is a planetary gear type known as "three speed". In today's terms it is considered a two-speed, because one of the three speeds is reverse.The Model T's transmission is controlled with three floor-mounted pedals, a revolutionary feature for its time, and a lever mounted to the road side of the driver's seat. The throttle is controlled with a lever on the steering wheel. The left-hand pedal is used to engage the transmission. With the floor lever in either the mid position or fully forward and the pedal pressed and held forward, the car enters low gear. When held in an intermediate position, the car is in neutral. If the left pedal is released, the Model T enters high gear, but only when the lever is fully forward – in any other position, the pedal only moves up as far as the central neutral position. This allows the car to be held in neutral while the driver cranks the engine by hand. The car can thus cruise without the driver having to press any of the pedals.
In the first 800 units, reverse is engaged with a lever; all units after that use the central pedal, which is used to engage reverse gear when the car is in neutral. The right-hand pedal operates the transmission brake – there are no brakes on the wheels. The floor lever also controls the parking brake, which is activated by pulling the lever all the way back. This doubles as an emergency brake.
Although it was uncommon, the drive bands could fall out of adjustment, allowing the car to creep, particularly when cold, adding another hazard to attempting to start the car: a person cranking the engine could be forced backward while still holding the crank as the car crept forward, although it was nominally in neutral. As the car utilizes a wet clutch, this condition could also occur in cold weather, when the thickened oil prevents the clutch discs from slipping freely. Power reaches the differential through a single universal joint attached to a torque tube which drives the rear axle; some models could be equipped with an optional two-speed rear Ruckstell axle, shifted by a floor-mounted lever which provides an underdrive gear for easier hill climbing.
Chassis / frame
The heavy-duty Model TT truck chassis came with a special worm gear rear differential with lower gearing than the normal car and truck, giving more pulling power but a lower top speed. A Model TT is easily identifiable by the cylindrical housing for the worm-drive over the axle differential. All gears are vanadium steel running in an oil bath.Transmission bands and linings
Two main types of band lining material were used:- Cotton – Cotton woven linings were the original type fitted and specified by Ford. Generally, the cotton lining is "kinder" to the drum surface, with damage to the drum caused only by the retaining rivets scoring the drum surface. Although this in itself did not pose a problem, a dragging band resulting from improper adjustment caused overheating of the transmission and engine, diminished power, and – in the case of cotton linings – rapid destruction of the band lining.
- Wood – Wooden linings were originally offered as a "longer life" accessory part during the life of the Model T. They were a single piece of steam-bent wood and metal wire, fitted to the normal Model T transmission band. These bands give a very different feel to the pedals, with much more of a "bite" feel. The sensation is of a definite "grip" of the drum and seemed to noticeably increase the feel, in particular of the brake drum.
Aftermarket transmissions and drives
Aftermarket transmissions generally fit one of four categories:
- Replacement transmission – usually a sliding gear/selective transmission, intended as a direct replacement for Ford's planetary-gear transmission.
- Front-mounted auxiliary transmission – designed to fit between the engine and Ford's transmission, to add additional gear ratios.
- Rear-mounted auxiliary transmission – mounted at the rear axle housing, and attached between it and the driveshaft, to add additional gear ratios.
- Multi-speed axle – designed to fit inside the differential's housing, to add additional gear ratios.
He also noted that auxiliary transmissions were valuable for Ford Ton-Trucks in commercial use, allowing for driving speeds to vary with their widely variable loads – particularly when returning empty – possibly saving as much as 50% of returning drive time.
