ASEA AND SJ TEST TILTING SUSPENSION WITH PANTOGRAPH ADJUSTMENT

An electronic pendulum or accelerometer senses the lateral acceleration in a curve, and the deflection of the pendulum determines the tilting angle of the coach. The air suspension raises one side of the coach body and lowers the other side; full tilting angle is obtained within 1.5 sec. The system is stable and unaffected by irregularities in the track; the air suspension itself provides a simple level control so that the relation between coach floor and platform height remains constant irrespective of whether the coach is loaded or empty. As well as practical tests, computer simulations of the equipment have been performed. The two-car electric unit used for the tests so far has a maximum speed of 120 km/h, but its gear ratio is to be altered to permit speeds up to 200 km/h.
