Torque Steer
Torque steer is the unintended influence of Torque#Machine torque, engine torque on the steering, especially in front-wheel drive, front-wheel-drive vehicles. For example, during heavy acceleration, the steering may pull to one side, which may be disturbing to the driver. The effect is manifested either as a tugging sensation in the steering wheel, or a veering of the vehicle from the intended path. Torque steer is directly related to differences in the forces in the contact patches of the left and right drive wheels. The effect becomes more evident when high torques are applied to the drive wheels because of a high overall reduction ratio between the engine and wheels, high engine torque, or some combination of the two. Torque steer is distinct from steering kickback. Causes Root causes for torque steer are: * Incorrect Tire#Sidewall, sidewall ply design allowing deformation of the tire sidewall. * Excessive horsepower/torque Asymmetries, Asymmetric driveshaft angles due to any ...

Torque
In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen point; for example, driving a screw uses torque to force it into an object, which is applied by the screwdriver rotating around its axis to the drives on the head. Historical terminology The term ''torque'' (from Latin , 'to twist') is said to have been suggested by James Thomson and appeared in print in April, 1884. Usage is attested the same year by Silvanus P. Thompson in the first edition of ''Dynamo-Electric Machinery''. Thompson describes his usage of the term as follows: Today, torque is referred to using d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fiat 127
The Fiat 127 is a supermini car produced by Italian car manufacturer Fiat Automobiles, Fiat from 1971 to 1983. It was introduced in 1971 as the replacement for the Fiat 850. Production of the 127 in Italy ended in 1983 following the introduction of its replacement, the Fiat Uno, although the nameplate continued to be used on cars imported from Brazil. The 127, designed by Pio Manzù, is generally regarded as one of the most influential small cars of all time, and more than any other as the car which defined the modern supermini – with its body configuration and engineering template being followed in almost all B-segment cars that followed. Superminis typically emulate the 127's transverse engine layout, with an end-on mounted transmission and front wheel drive, and are sold overwhelmingly in hatchback format. __TOC__ Series 1 Developed towards the end of the 1960s, the Fiat 127 was launched as a two-door saloon in April 1971. A three-door hatchback, using an identical body p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiat 128
The Fiat 128 is a transverse front-engine, front wheel drive small family car manufactured and marketed by Fiat from 1969 to 1985 as a two- or four-door sedan, three- or five-door station wagon as well as two- or three-door coupé. The 128 running gear and engine, reconfigured for a mid-engined layout, were used in the Fiat X1/9 sports car. With engineering by Dante Giacosa and engine design by Aurelio Lampredi, the 128 was noted for its relatively roomy passenger and cargo volume — enabled by a breakthrough innovation to the front-engine, front-drive layout which became the layout "adopted by virtually every other manufacturer in the world" for front-wheel drive. Fiat promoted in its advertising that mechanical features consumed only 20% of the vehicle's volume. Named European Car of the Year in 1970, over three million were ultimately manufactured. In 2012 automotive journalist Jamie Kitman called the 128 a "pioneer of the small cars we drive today." Development W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autobianchi
Autobianchi () was an Italian automobile manufacturer, created jointly by Bianchi (company), Bianchi, Pirelli and Fiat in 1955. Autobianchi produced only a handful of models during its lifetime, which were almost exclusively small cars, with the biggest being the short-lived Autobianchi A111, a small family car. Autobianchis were priced higher than Fiat models of similar size and the brand was used by Fiat to test innovative concepts which later found their way into mainstream Fiat vehicles; these concepts included fibreglass bodies and front-wheel drive. The most famous Autobianchi models include the Autobianchi A112, A112 released in 1969, a small hatchback very popular in Italy for racing, and which ceased production in 1986; as well as the Autobianchi Y10, Y10, which was the first car to use Fiat's new FIRE (Fully Integrated Robotised Engine).

Boxer Engine
A flat engine is a Internal combustion engine#Reciprocating engines, 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 configuration, 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 (Benz Contramotor) was built in 1897 by Karl Benz. Flat engines have been used in aviation, motorcycle and automobile applications. They are now less common in car ...

Audi
Audi AG () is a German automotive manufacturer of luxury vehicles headquartered in Ingolstadt, Bavaria, Germany. A subsidiary of the Volkswagen Group, Audi produces vehicles in nine production facilities worldwide. The origins of the company are complex, dating back to the early 20th century and the initial enterprises ( Horch and the ''Audiwerke'') founded by engineer August Horch. Two other manufacturers ( DKW and Wanderer) also contributed to the foundation of Auto Union in 1932. The modern Audi era began in the 1960s, when Auto Union was acquired by Volkswagen from Daimler-Benz.

Renault 21
The Renault 21 is a large family car produced by French automaker Renault between 1986 and 1994. It was also sold in North America initially through American Motors dealers as the Renault Medallion and later through Jeep-Eagle dealers as the Eagle Medallion. A total of 2,096,000 units were produced. The Renault 21 Sedan (automobile), saloon was launched in the beginning of 1986, as the successor to the successful Renault 18, and this was followed a few months later by the seven seater station wagon, the R21 Nevada, marketed as the Savanna in the United Kingdom.

Renault 18
The Renault 18 is a large family car produced by French manufacturer Renault between 1978 and 1989, with South American production continuing until 1994. It formed the basis for the closely related Renault Fuego Coupé, with which it shared its floorpan and drivetrain, but with the Fuego initially using the negative offset type front suspension from the larger Renault 20/30, which became standardized across the 18 range from the 1983 model year onwards. Development The Renault 18 was intended as a replacement for the Renault 12, which, having been in production since 1969, was beginning to show its age by the late 1970s, though the 12 was kept in production alongside the 18 until 1980. Unlike the earlier car, the 18 was designed quickly; the time between its initial conception and its actual launch date was only eighteen months, primarily due to the fact that the 18 was based upon the 12's underpinnings. Production peaked early: 1979 was the R18's biggest year, after which sales ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
