Train Tilting Technology
As a leading global supplier of electromechanical drive systems, we have developed technology and products designed for the most challenging environments. Used to improve passenger comfort, one such development is the electro-mechanical high-speed train tilting drive system.
As a train speeds around a curve the people and objects inside can be misplaced or thrown off balance due to its centripetal force, often causing passenger discomfort. Passenger discomfort is reduced by tilting the coach body towards the inside of the curve. A sensor system mounted on the forward bogie detects the changing track motion and a train-tilting computer transmits the optimum tilting angle for each coach, via a multi-vehicle bus, to the individual coach-tilting computers that control the tilting drives.
The linear tilting drive is designed as a compact, low-backlash transmission unit. AC synchronous motors equipped with rare-earth magnets are used as e-motors . The rotary sensor that detects the angular position of the motor shaft is a digital encoder with an incremental transmitter. The sensor also makes it possible to measure the absolute value of the linear drive position. The position control circuit can therefore be designed without additional external position sensors.
Our train tilting technology enables an angle of approximately +8˚ and produces exceptionally responsive tilting due to high precision positioning in conjunction with fast reaction times, resulting in smooth car body movements.
