Tracta
Tracta was a French car maker based in Asnières, Seine, that was active between 1926 and 1934. They were pioneers of front-wheel-drive vehicles. The business The business was directed and cars were designed by the engineer Jean-Albert Grégoire, who controlled the business, with financial support from his friend Pierre Fenaille. The cars The cars were initially built in small numbers for competition use, but they were exhibited and offered for road use at the 1927 Paris Motor Show. They used a front-wheel-drive system featuring Grégoire's patented Tracta constant-velocity joint and sliding pillar independent front suspension and a live axle with quarter-elliptic leaf springs at the rear. 1100, 1200, 1500 and 1600 cc engines made by S.C.A.P. were available with optional Cozette supercharger. The 1500 cc car was claimed to reach 80 mph. The first cars were made in a workshop in Versailles but Grégoire soon moved to a small factory in Asnières. After about 1 ...

1928 24 Hours Of Le Mans
The 1928 24 Hours of Le Mans was the 6th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 16 and 17 June 1928. Bentley director Woolf Barnato and Australian-born Bernard Rubin in a Bentley 4½ Litre gave the company back-to-back victories after a race-long duel with the Stutz of Édouard Brisson and Robert Bloch. In the process they won the inaugural prize for overall distance. The big publicity from the previous year's race and the White House crash raised manufacturer interest and several British and American companies brought teams to the race.Clausager 1982, p.38-9 In fact foreign cars outnumbered French ones for the first time. The race started at a record pace, but after two of the Bentleys and the Ariès retired early, it became a one-on-one duel between the Bentley and the Stutz. They traded positions through the night and into the next morning. Going into the final hours the British car was suffering from water leaks and overheating, while the ...

1930 24 Hours Of Le Mans
The 1930 24 Hours of Le Mans was the 8th Grand Prix of Endurance that took place at the Circuit de la Sarthe on 21 and 22 June 1930. It saw the first appearance of a German car and the first entry from female drivers.Clausager 1982, p.43-5 In the smallest ever field in the Le Mans history; there were only 17 starters. This was a race of two halves. At the start the Mercedes of Rudolf Caracciola/Christian Werner was pursued by the supercharged ‘Blower’ Bentley of Tim Birkin. Twice he passed the white car on the Mulsanne Straight and both times he was thwarted by a rear-tyre blowout. Then Sammy Davis chased in a works Bentley. When that car was put into the sandbank at Pontlieue corner, it was the other works Bentley of Woolf Barnato and Glen Kidston taking up the Germans’ challenge. The lead changed a number of times into the night, until at 1.30am when the Mercedes was retired with a broken dynamo and a flat battery. After that it became a procession for the remaining Bent ...

Constant-velocity Joint
Constant-velocity joints (also known as homokinetic or CV joints) are mechanical joints which allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or Backlash (engineering), play. They are mainly used in front-wheel drive vehicles. Modern rear-wheel drive cars with independent rear suspension typically use CV joints at the ends of the rear axle halfshafts and increasingly use them on the drive shaft. History The universal joint, one of the earliest means of transmitting power between two angled shafts, was invented by Gerolamo Cardano in the 16th century. The fact that it failed to maintain constant velocity during rotation was recognized by Robert Hooke in the 17th century, who proposed the first constant velocity joint, consisting of two Cardan joints offset by 90 degrees, so as to cancel out the velocity variations. This is the #Double_Cardan, "double Cardan". Many different types of consta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Albert Grégoire
Jean-Albert Grégoire (7 July 1899 in Paris – 19 August 1992) was one of the great pioneers of the front-wheel-drive car. He contributed to the development of front-wheel-drive vehicles in two ways. The first way was in developing and promoting the Tracta joint (designed by his friend Pierre Fenaille), which was, until manufacturing techniques had progressed sufficiently to allow the successful manufacture of the constant velocity joints commonly in use today, the preferred choice of most manufactures of vehicles that had driven front wheels. Tracta joints were used by many of the pioneers of front-wheel drive, including DKW between 1929 and 1936 and Adler from 1932 to 1939 as well as the cars designed by J A Grégoire that will be mentioned later. The Tracta joint was fitted to most of the military vehicles that had driven front wheels used by most of the combatants in the Second World War. They included Laffly and Panhard in France, Alvis and Daimler in the UK and Willys in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front-wheel-drive
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the front wheels only. Most modern front-wheel drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel drive and four-wheel drive vehicles. Location of engine and transmission By far the most common layout for a front-wheel drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 "fardier à vapeur", was a front-wheel driven three-wheeled steam-tractor. It then took at least a century, for the firs ...

Sliding Pillar Suspension
A sliding pillar suspension is a form of independent front suspension for light cars. The stub axle and wheel assembly are attached to a vertical pillar or kingpin which slides up and down through a bush or bushes which are attached to the vehicle chassis, usually as part of transverse outrigger assemblies, sometimes resembling a traditional beam axle, although fixed rigidly to the chassis. Steering movement is provided by allowing this same sliding pillar to also rotate. Sliding pillar independent suspension was first used by Decauville in 1898, the first recorded instance of independent front suspension on a motor vehicle. In this system, the stub axle carrying the wheel was fixed to the bottom of a pillar which slid up and down through a bush in a transverse axle fixed to the front of the chassis. The top of the pillar was fixed and pivoted on a transverse semi-elliptic leaf spring. This system was copied by Sizaire-Naudin a few years later. In around 1904, the New Jers ...

Hotchkiss Et Cie
Société Anonyme des Anciens Etablissements Hotchkiss et Compagnie was a French arms and, in the 20th century, automobile manufacturer first established by United States gunsmith Benjamin B. Hotchkiss. He moved to France and set up a factory, first at Viviez near Rodez in 1867, manufacturing arms used by the French in the Franco-Prussian War of 1870, then moving at Saint-Denis near Paris in 1875. It was merged into and succeeded by Thomson-CSF, now Thales Group. Arms An example of the company's output was the Hotchkiss revolving cannon (see picture from a privately circulated book dated 1874 by Alfred Koerner, later chairman of the company). The cannon had five barrels each able to fire 43 shells a minute a distance of one mile; it was made in four sizes from 37 mm to 57 mm, the largest intended for naval use. At the turn of the twentieth century, the company introduced the gas-actuated Hotchkiss machine gun, a sturdy and reliable weapon which was widely used duri ...

Facel Vega FVS
The Facel Vega FV/FVS is a car produced by French automaker Facel from 1954 until 1959. It continued until 1962 as the HK500. History FV The Facel 'Vega' was launched at the 1954 Paris Salon. By 1956, the cars were called FVS (for Facel Vega Sport), with earlier cars often being referred to as simply "FV". The 1954 versions of the Facel were fitted with a DeSoto Firedome (Chrysler) 4.5 litre Hemi V8 engine, paired with either Chrysler's two-speed Powerflite automatic transmission or, at extra cost, a four-speed manual made by Pont-à-Mousson. At this stage, the FV was capable of a top speed from , depending on which rear axle ratio was installed. The chassis, designed by Lance Macklin, was tubular framed, featuring coil springs and double wishbones at the front, with a leaf-sprung live rear axle. The styling, by Daninos himself, was somewhat American and perhaps a bit heavy, with rudimentary tail fins. The body was an expanded version of the earlier, Facel-bodied Simca/Ford ...

AC Cars
AC Cars, originally incorporated as Auto Carriers Ltd., is a British specialist automobile manufacturer and one of the oldest independent car makers founded in Britain. As a result of bad financial conditions over the years, the company was renamed or liquidated many times until its present form. In 2022, the new corporate structure began the production of new AC Cobra models, with a slightly modified structure to adapt it to modern safety and technology requirements and obtain the European road homologation certificate History The Weller brothers prototype The first car from what eventually became AC was presented at the Crystal Palace motor show in 1903; it was a 20 HP touring car and was displayed under the Weller name. The Weller brothers of West Norwood, London, planned to produce an advanced car. However, their financial backer and business manager John Portwine, a butcher, thought the car would be too expensive to produce and encouraged Weller to design an ...

Flat Engine
A flat engine is a piston engine where the cylinders are located on either side of a central crankshaft. Flat engines are also known as horizontally opposed engines, however this is distinct from the less common opposed-piston engine design, whereby each cylinder has two pistons sharing a central combustion chamber. The most common configuration of flat engines is the boxer engine configuration, in which the pistons of each opposed pair of cylinders move inwards and outwards at the same time. The other configuration is effectively a V engine with a 180-degree angle between the cylinder banks; in this configuration each pair of cylinders shares a single crankpin, so that as one piston moves inward, the other moves outward. The first flat engine was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in cars than straight engines (for engines with less than six cylinders) and V engines (for engi ...

Henri Chapron
Henri Chapron (30 December 1886 - 14 May 1978) was a prominent French automobile coachbuilder. His carrosserie, created in 1919, was located in the Paris suburb of Levallois-Perret. Chapron was born in Nouan-le-Fuzelier (Sologne), and began his career developing custom body designs for French luxury vehicles, like Talbot, Delage, and Delahaye, in the 1920s. France ceased building vehicles of this type in the 1950s, due to tax legislation that made luxury vehicles prohibitively expensive in France. Chapron switched his attention to the recently launched Citroën DS. Chapron’s first rebodied DS coupe was the 1958 ''Le Paris.'' At first, Chapron purchased these vehicles and customised them as one-off creations. Many of these became unique convertible variants. His DS convertible caused a sensation at the 1958 Motor Show. Citroën managers came to see him in Levallois to offer him a production agreement. For 2 years, the Chapron and Citroën teams worked hand in hand in order ...
