A wheel is a circular device that is capable of rotating on an axle.
Wheel may also refer to:
A bogie comprises two or more wheelsets, in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached or be quickly detachable. It may include suspension components within it, or be solid and in turn be suspended. It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung, or held in place by other means.
A prayer wheel, or mani wheel, is a cylindrical wheel for Buddhist recitation. The wheel is installed on a spindle made from metal, wood, stone, leather, or coarse cotton. Prayer wheels are common in Tibet and areas where Tibetan culture is predominant.
A wheel is a rotating component that is intended to turn on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel.
A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others. A common use of differentials is in motor vehicles, to allow the wheels at each end of a drive axle to rotate at different speeds while cornering. Other uses include clocks and analogue computers. Differentials can also provide a gear ratio between the input and output shafts. For example, many differentials in motor vehicles provide a gearing reduction by having fewer teeth on the pinion than the ring gear.
The MacPherson strut is a type of automotive suspension system that uses the top of a telescopic damper as the upper steering pivot. It is widely used in the front suspension of modern vehicles. The name comes from American automotive engineer Earle S. MacPherson, who invented and developed the design.
Steering is the control of the direction of motion or the components that enable its control. Steering is achieved through various arrangements, among them ailerons for airplanes, rudders for boats, cylic tilting of rotors for helicopters, and many more.
Surf is the region of breaking waves on a shoaling area of water such as a shoreline or reef.
Understeer and oversteer are vehicle dynamics terms used to describe the sensitivity of the vehicle to changes in steering angle associated with changes in lateral acceleration. This sensitivity is defined for a level road for a given steady state operating condition by the Society of Automotive Engineers (SAE) in document J670 and by the International Organization for Standardization (ISO) in document 8855. Whether the vehicle is understeer or oversteer depends on the rate of change of the understeer angle. The Understeer Angle is the amount of additional steering that must be added in any given steady-state maneuver beyond the Ackermann steer angle. The Ackermann Steer Angle is the steer angle at which the vehicle would travel about a curve when there is no lateral acceleration required.
Kingpin or king pin may refer to:
A limited-slip differential (LSD) is a type of differential gear train that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts. Limited-slip differentials are often known by the generic trademark Positraction, a brand name owned by General Motors and originally used for its Chevrolet branded vehicles.
Automobile handling and vehicle handling are descriptions of the way a wheeled vehicle responds and reacts to the inputs of a driver, as well as how it moves along a track or road. It is commonly judged by how a vehicle performs particularly during cornering, acceleration, and braking as well as on the vehicle's directional stability when moving in steady state condition.
Herbert Jansch was a Scottish folk musician and founding member of the band Pentangle. He was born in Glasgow and came to prominence in London in the 1960s as an acoustic guitarist and singer-songwriter. He recorded more than 28 albums and toured extensively from the 1960s to the 21st century.
The wheel size for a motor vehicle or similar wheel has a number of parameters.
Rolling is a type of motion that combines rotation and translation of that object with respect to a surface, such that, if ideal conditions exist, the two are in contact with each other without sliding.
Rosanne Cash is an American singer-songwriter and author. She is the eldest daughter of country musician Johnny Cash and his first wife, Vivian Cash.
Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation of the wheel, roadbed, etc., is recovered when the pressure is removed. Two forms of this are hysteresis losses, and permanent (plastic) deformation of the object or the surface. Note that the slippage between the wheel and the surface also results in energy dissipation. Although some researchers have included this term in rolling resistance, some suggest that this dissipation term should be treated separately from rolling resistance because it is due to the applied torque to the wheel and the resultant slip between the wheel and ground, which is called slip loss or slip resistance. In addition, only the so-called slip resistance involves friction, therefore the name "rolling friction" is to an extent a misnomer.
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of these motions began in the late 19th century and continues today.
The turning radius of a vehicle defines the minimum dimension of available space required for that vehicle to make a semi-circular U-turn without skidding. The Oxford English Dictionary describes turning circle as "the smallest circle within which a ship, motor vehicle, etc., can be turned round completely". The term thus refers to a theoretical minimal circle in which for example an aeroplane, a ground vehicle or a watercraft can be turned around.
"The Way We Make a Broken Heart" is a song written by John Hiatt. It was recorded by Ry Cooder in 1980 on his album Borderline. "The Way We Make a Broken Heart" was covered by both John Hiatt and Rosanne Cash in 1983 as a duet. The single was produced by Scott Mathews and Ron Nagle, however, Geffen Records did not release the single. Willy DeVille performed this song twice in Berlin 2002; once in an unplugged version and once with his electric band. This is documented on his 2002 album Live in Berlin. Asleep At The Wheel also recorded the song on their 1985 album Pasture Prime under the title "This Is the Way We Make a Broken Heart".
The Austin 15-20 is the smaller-engined of the almost identical pair of new cars announced by Herbert Austin in February 1906. A very complete catalogue with detailed specifications was issued at the same time. As well as the engine's smaller bore the 15-20 differed from the 25-30 by being only available with a live rear axle and not chain-drive. Otherwise the specifications were the same, the very minor differences are detailed below.
