Abstract
A rail vehicle having at least a first carriage and a second carriage intercoupled via a carriage coupling device that has a variable resistance to twisting of the at least first carriage relative to the second carriage, wherein a first resistance torque gradient of the carriage coupling device at a first angular position of the at least first carriage relative to the second carriage in a direction of rotation is greater in magnitude than a second resistance torque gradient of the carriage coupling device at a second angular position of the at least first carriage relative to the second carriage in the same direction of rotation, where the first angular position is associated with a lesser twisting of the at least first carriage relative to the second carriage than the second angular position, such that an improved driving behavior of the rail vehicle is achieved, particular when entering track curves.
