Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).
The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...
The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
Traction (mechanics), adhesive friction or force; Traction vector, in mechanics, the force per unit area on a surface, including normal and shear components; Traction motor, an electric motor used for propulsion of a vehicle, for example a car or a locomotive; Railway electric traction, the use of electric motors to propel rail cars
The device can be set to repel specific chemical elements. It was used to create a bubble habitat on the ocean floor, and as the propulsion system for his spacecraft Challenger. The Sector General books by James White: The 1963 novel Star Surgeon is the source of the combined tractor/pressor beam weapon called the Rattler.
A highsider is a type of bike motion which is caused by a rear wheel gaining traction when it is not facing in the direction of travel, usually after slipping sideways in a curve. [9] This can occur under heavy braking, acceleration, a varying road surface, or suspension activation, especially due to interaction with the drive train. [ 71 ]
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic " if the generated electrical power is dissipated as heat in brake grid resistors , and " regenerative " if the power is returned to the supply line.
Adhesion traction is the friction between the drive wheels and the steel rail. [1] Since the vast majority of railways are adhesion railways, the term adhesion railway is used only when it is necessary to distinguish adhesion railways from railways moved by other means, such as by a stationary engine pulling on a cable attached to the cars or ...
