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 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
Tractive effort can be theoretically calculated from a locomotive's mechanical characteristics (e.g., steam pressure, weight, etc.), or by actual testing with strain sensors on the drawbar and a dynamometer car. Power at rail is a railway term for the available power for traction, that is, the power that is available to propel the train.
It is shown that for a passenger car, when the tractive force is about 40% of the maximum traction, the slip resistance is almost equal to the basic rolling resistance (hysteresis loss). But in case of a tractive force equal to 70% of the maximum traction, slip resistance becomes 10 times larger than the basic rolling resistance. [1]
If you're in the market for a new car, keep in mind that sticker prices don't include the cost of gas mileage -- or maintenance. Sometimes a set of wheels with a modest price tag can be among the ...
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
