Radius Rod
A radius rod (also called a radius arm, torque arm, torque spring, and torsion bar) is a suspension link intended to control wheel motion in the longitudinal (fore-aft) direction. The link is connected (with a rubber or solid bushing) on one end to the wheel carrier or axle, on the other to the chassis or unibody of the vehicle. Radius rods are typically mounted ahead of the wheel. In that position they resist dive under braking forces and wheel hop under acceleration. Radius rods are also sometimes used in aircraft with fixed (non retractable) undercarriages. Radius rods in aircraft must be regularly inspected because their failure will cause unrestrained swerving of the wheel. Radius rods are customarily made of stamped steel or aluminum for lightness, as they are part of the vehicle's unsprung weight. Improvements in composite materials technology make possible plastic suspension links, although they are still uncommon. Other suspension components can be made to act as r ...

Radius Rod Sway Bar
In classical geometry, a radius (: radii or radiuses) of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The radius of a regular polygon is the line segment or distance from its center to any of its vertices. The name comes from the Latin ''radius'', meaning ray but also the spoke of a chariot wheel. as a function of axial position ../nowiki>" Spherical coordinates In a spherical coordinate system, the radius describes the distance of a point from a fixed origin. Its position if further defined by the polar angle measured between the radial direction and a fixed zenith direction, and the azimuth angle, the angle between the orthogonal projection of the radial direction on a reference plane that passes through the origin and is orthogonal to the zenith, and a fixed reference direction in that plane.

Unsprung Weight
The unsprung mass (colloquially unsprung weight) of a vehicle is the mass of the suspension, wheels or tracks (as applicable), and other components directly connected to them. This contrasts with the sprung mass (or weight) supported by the suspension, which includes the body and other components within or attached to it. Components of the unsprung mass include the wheel axles, wheel bearings, wheel hubs, tires, and a portion of the weight of driveshafts, springs, shock absorbers, and suspension links. Brakes that are mounted inboard (i.e. as on the drive shaft, and not part of the wheel or its hub) are part of a vehicle's sprung mass. Effects The unsprung mass of a typical wheel/tire combination represents a trade-off between the pair's bump-absorbing/road-tracking ability and vibration isolation. Bumps and surface imperfections in the road cause tire compression, inducing a force on the unsprung mass. The unsprung mass then reacts to this force with movement of its ...

Drag Racing
Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly , with a shorter, distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s. The history of automobiles and motorcycles being used for drag racing is nearly as long as the history of motorized vehicles themselves, and has taken the form of both illegal street racing and as a regulated motorsport. History Drag racing started in the 1940s. World War II veterans were prominently involved, and some early drag races were done at decommissioned airc ...

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] |
Hotchkiss Drive
The Hotchkiss drive is a shaft drive form of Transmission (mechanics), power transmission. It was the dominant means for front-engine, rear-wheel drive layout automobile, cars in the 20th century. The name comes from the French automobile manufacturer Hotchkiss et Cie, Hotchkiss, although other makers, such as Peerless Motor Company, Peerless, used similar systems before Hotchkiss. During the early part of the 20th century chain drive, chain-drive power transmission was the main direct drive competitor of the Hotchkiss system, with the torque tube also popular until the 1950s. The problem is how to transfer the axle torque, which is the tendency of the drive axle to spin in the opposite direction of the drive wheels, to the car. The problem is also seen in braking, when the axle is forced in the same direction as the braking wheels. Most shaft-drive systems consist of a drive shaft (also called a "propeller shaft" or Cardan shaft) extending from the transmission (mechanics), tran ...

Leaf Spring
A leaf spring is a simple form of spring (device), spring commonly used for suspension (vehicle), 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 vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates that are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam Axle
A beam axle, rigid axle, or solid axle is a suspension (vehicle), dependent suspension design in which a set of wheels is connected laterally by a single beam or shaft. Beam axles were once commonly used at the rear wheels of a vehicle, but historically, they have also been used as front axles. In most automobiles, beam axles have been replaced with front (IFS) and rear independent suspensions (IRS). Implementation With a beam axle, the camber angle between the wheels is the same regardless of its location in the travel of the suspension. A beam axle's location in the fore and aft directions is constrained by one of several suspension components, including Trailing-arm suspension, trailing arms, semi-trailing arms, radius rods, and leaf springs. The lateral location can be constrained by a Panhard rod, a Scott Russell linkage, a Watt's linkage, or some other arrangement, most commonly by the leaf springs. Shock absorbers and either leaf springs, coil springs, or air suspension, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shock Absorber
A shock absorber or damper is a mechanical or hydraulics, hydraulic device designed to absorb and Damping ratio, damp shock (mechanics), shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically thermal energy, heat) which is then dissipated. Most shock absorbers are a form of dashpot (a damper which resists motion via viscous friction). Description Pneumatic and hydraulic shock absorbers are used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston (see below). One design consideration, when designing or choosing a shock absorber, is where that energy will go. In most shock absorbers, energy is converted to heat inside the viscous fluid. In hydraulic cylinders, the hydraulic fluid heats up, while in Pneumatic cylinder, air cylinders, the hot air is usually exhausted to the atmosphere. In other types of ...

Oldsmobile Toronado
The Oldsmobile Toronado is a personal luxury car manufactured and marketed by the Oldsmobile division of General Motors from 1966 to 1992 over four generations. The Toronado was noted for its transaxle version of GM's Turbo-Hydramatic transmission, making it the first U.S.-produced front-wheel drive automobile since the demise of the Cord 810/812 in 1937. The Toronado used the GM E platform introduced by the rear-wheel drive Buick Riviera in 1963 and adopted for the front-wheel drive 1967 Cadillac Eldorado. The three models shared the E platform for most of the Toronado's 26-year history. Etymology The name "Toronado" had no prior meaning and was originally selected for a 1963 Chevrolet show car. First generation (1966–1970) The Toronado began as a design painting by Oldsmobile stylist David North in 1962. His "Flame Red Car" was a compact sports/personal car never intended for production. A few weeks after the design was finished, however, Oldsmobile division was infor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Composite Materials
A composite or composite material (also composition material) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Composite materials with more than one distinct layer are called ''composite laminates''. Typical engineered composite materials are made up of a binding agent forming the ''matrix'' and a Filler (materials), filler material (particulates or fibres) giving ''substance'', e.g.: * Concrete, reinforced concrete and masonry with cement, lime or Mortar (masonry), mortar (which is itself a composite material) as a binder * Composite wood such as glulam and plywood with wood glue as a binder * Reinforced plastics, such as fiberglass and fibre-rein ...

Aluminum
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...
