Cornering force

The cornering force is the force in the contact zone of the wheel and the " road " perpendicular to the section line road and wheel center plane. It acts on the wheel under the roadway is in vehicles with pneumatic tires, the road to understand the rail in rail vehicles.

Road vehicles

For tires, the cornering force of skew angle, wheel load, slip, fall, and the coefficient of friction between tires and road surface depends.

The cornering forces are transmitted via the elastically coupled to the rim tires for construction. The transferable from the tire to the road forces make this a limiting element for cornering represents the height of the maximum cornering force is also dependent on the acceleration or braking force next to the coefficient of friction between the tires and the road. The relationships can be illustrated with the Kamm's circle.

Rail vehicles

For rail vehicles, the design of the rail ( especially the curve slope) and the wheel determines the maximum cornering force. Dynamic instabilities and the area defined by the position of the center of gravity tilt angle limit the maximum possible speed curve of the vehicle concerned.
