摘要： An active steering bogie for railway vehicles can improve the driving stability of a railway vehicle running at a high speed, thereby increasing the stability of the vehicle, so that the vehicle is not derailed, and can also minimize the vibration of wheels and rails during the driving of the vehicle, thereby ensuring driving comfort. The active steering bogie uses leverage, has a simple structure of links for steering wheel shafts of the bogie, and can use leverage to actuate the links with a small force, thereby reducing the weight of the bogie and facilitating maintenance. The active steering bogie includes a front steering unit, hinged to front axle boxes on both sides of a front wheel shaft to steer the front wheel shaft; and a rear steering unit, hinged to rear axle boxes on both sides of a rear wheel shaft to steer the rear wheel shaft.

摘要： The present invention relates to an active steering control device and method for a railroad vehicle, and more specifically, to an active steering control device and method for a railroad vehicle, which can smoothly steer a moving railroad vehicle by estimating the radius of curvature of a curved line in real-time when the train moves on the curved line and controlling an optimal steering angle of the wheel and axle according to the estimated radius of curvature, and can remarkably reduce an angle of attack which exists between the curved line and the wheel and axle. The invention includes: a measurer that measures drive data of the moving railroad vehicle; an estimator that estimates the radius of curvature of the curved line on which the railroad vehicle is moving, by using the data measured in the measuring unit; a calculator that sets a target value of the steering angle of the wheel and axle of the moving railroad vehicle, by using the radius of curvature estimated in the estimator; a controller that generates a steering control signal on the wheel and axle by comparing an actual steering angle of the wheel and axle with the target value of the steering angle of the wheel and axle, which is set in the calculator; and an actuator that steers the wheel and axle using the steering signal of the controller.
