    Abstract: Disclosed is a vehicle, in particular rail vehicle, with a wagon body and an running gear on which the wagon body is supported, wherein the wagon body and the running gear define a vehicle longitudinal direction, a vehicle transverse direction and a vehicle height direction. A tilting mechanism is arranged between the wagon body and the running gear, which is designed to impose, during a transverse displacement in the vehicle transverse direction, upon the wagon body a rolling motion about a rolling axis parallel to the vehicle longitudinal direction. The tilting mechanism comprises a transverse decoupling device, which is designed to reduce the stiffness of the tilting mechanism against a pure transverse displacement of the wagon body with respect to the running gear. The invention furthermore relates to a corresponding tilting mechanism.

  • Height adjustable secondary suspension for a rail vehicle
    Patent number: 10442448
    Abstract: A secondary suspension system for a railcar comprises a chassis, a primary spring, a levelling actuator, a first hydraulic circuit and a secondary spring. The levelling actuator is adapted to be connected to the carbody. A piston shoulder, located at the lower portion of the piston and below an opening in the chassis, reaches farther than the opening so as to be capable of catching the chassis. The secondary spring is at least partially positioned underneath the piston shoulder. The piston is operative to adopt a high position inside the body under a pressure of a hydraulic fluid injected in a lower chamber below a piston head. This makes the piston shoulder abut against the chassis, thereby compressing the primary spring between the body and the chassis without compressing the secondary suspension.
