A dumb iron is a "curved side piece of a chassis, to which the front springs are attached." [1]
This is an older term, applicable mainly to vehicles built before 1950, and which had their front axle suspended on leaf springs.
At the front of the car, dumb irons project forward, providing a location to attach the front of the leaf springs.
A Panhard rod is a suspension link that provides lateral location of the axle. Originally invented by the Panhard automobile company of France in the early twentieth century, this device has been widely used ever since.
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process.
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different.
A leaf spring is a simple form of spring commonly used for the suspension in wheeled vehicles. Originally called a laminated or carriage spring, and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of springing, appearing on carriages in France in the mid-17th century in the form of the two-part elbow spring, and from there migrating to England and Germany.
The Fiat Dino was a front-engine, rear-wheel-drive sports car produced by Fiat from 1966 to 1973. The Dino name refers to the Ferrari Dino V6 engine, produced by Fiat and installed in the cars to achieve the production numbers sufficient for Ferrari to homologate the engine for Formula 2 racing.
Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically independently of the others. This is contrasted with a beam axle or deDion axle system in which the wheels are linked – movement on one side does not affect the wheel on the other side. "Independent" refers to the motion or path of movement of the wheels or suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms. The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together.
A monster truck is a specialized off-road vehicle with a heavy duty suspension, four-wheel steering, large-displacement V8 engines and oversized tires constructed for competition and entertainment uses. Originally created by modifying stock pickup trucks and sport utility vehicles (SUVs), they have evolved into purpose-built vehicles with tube-frame chassis and fiberglass bodies rather than metal. A competition monster truck is typically 12 feet (3.7 m) tall, and equipped with 66-inch (1.7 m) off-road tires.
A bicycle fork is the part of a bicycle that holds the front wheel.
The Triumph Spitfire is a British front-engined, rear-wheel drive, two-passenger convertible sports car introduced at the London Motor Show in 1962 and manufactured between 1962-1980. Styled for Standard-Triumph in 1957 by Italian designer Giovanni Michelotti, the Spitfire was manufactured for the duration of its production at the Standard-Triumph Canley works — and evolved over a series of five production iterations, with approximately 315,000 manufactured over 18 years.
A double wishbone suspension is an independent suspension design for automobiles using two wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff and more.
A swingarm, or "swinging arm" (UK), originally known as a swing fork or pivoted fork, is a single or double sided mechanical device which attaches the rear wheel of a motorcycle to its body, allowing it to pivot vertically. The main component of the rear suspension of most modern motorbikes and ATVs, it holds the rear axle firmly, while pivoting to absorb bumps and suspension loads induced by the rider, acceleration, and braking.
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.
The Hotchkiss drive is a shaft drive form of power transmission. It was the dominant means for front-engine, rear-wheel drive layout cars in the 20th century. The name comes from the French automobile manufacturer Hotchkiss, although other makers, such as Peerless, used similar systems before Hotchkiss.
The Type 13 was the first true Bugatti car. Production of the Type 13, and later Types 15, 17, 22, and 23, began with the company's founding in 1910 and lasted through 1920, with 435 examples produced. Most road cars used an eight-valve engine, though five Type 13 racers had 16-valve heads, some of the first ever produced. The road cars became known as pur-sang ("thoroughbred") in keeping with Ettore Bugatti's feelings for his designs.
Intel High Definition Audio (IHDA) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as successor to its AC'97 PC audio standard.
The Mint Chicks were a New Zealand noise rock/art punk group originally from Auckland who relocated to Portland, Oregon, USA in 2007. They are known for mixing pop hooks and structures with elements of noise rock and experimental music and also for their exciting live performances, where Kody and Ruban Nielson have been known to climb P.A. stacks, hang from lighting rigs, destroy guitars, engage in self-harm and even attack the stage with a chainsaw.
A Corvette leaf spring is a type of independent suspension that utilizes a fiber-reinforced plastic (FRP) mono-leaf spring instead of more conventional coil springs. It is named after the Chevrolet Corvette, the American sports car for which it was originally developed and first utilized. A notable characteristic of this suspension configuration is the mounting of the mono-leaf spring such that it can serve as both ride spring and anti-roll spring. In contrast to many applications of leaf springs in automotive suspension designs, this type does not use the spring as a locating link. While this suspension type is most notably associated with several generations of the Chevrolet Corvette the design has been used in other production General Motors cars, as well as vehicles from Volvo Cars and Mercedes-Benz Sprinter van. Fiat produced cars with a similar configuration, using a multi-leaf steel spring in place of the FRP mono-leaf spring.
The Leyland Eight was a luxury car produced by Leyland Motors from 1920 to 1923.
Transverse leaf spring front suspension is a type of automotive front suspension, whose usage is most well known in Ford Motor Company products from 1908 to 1948. "Suicide front axle" is a term that has been used for it.
Dumb and Dumber To is a 2014 American buddy comedy film co-written and directed by the Farrelly brothers.
