ABSTRACT:
Axle control mechanism for rail vehicles having two or more axles. The two journal boxes of one wheel set are interconnected with the respectively opposed journal boxes of the other wheel set by a hydraulic system. A movement of one of the wheel sets brings about a movement of the other wheel set. Each journal box housing of the two wheel sets is connected by a hydraulic cylinder, which has a double acting piston and is disposed in the longitudinal direction of the truck or undercarriage frame, to this truck or undercarriage frame. Of the two hydraulic cylinders located on the same longitudinal side of the truck or undercarriage frame, one working chamber of one of these hydraulic cylinders is interconnected with the opposed working chamber of the other hydraulic cylinder, and vice versa, via hydraulic lines. A piston movement in one of the in-line and successively arranged hydraulic cylinders brings about an oppositely directed piston movement in the other hydraulic cylinder, thus accomplishing opposite turning movements of the two wheel sets.
