  • Patent number: 11787450
    Abstract: A level control system adjusts the level of a vehicle, in particular a rail vehicle, and includes at least one level control cylinder and a level control piston. The level control piston is at least partly received in the level control cylinder in a movable manner. The level control cylinder has a collar-shaped shoulder, and the level control system has a first fixing disc which is connected to the level control piston in order to transmit a lifting movement. At least one spacer element is arranged between the collar-shaped shoulder of the level control cylinder and the first fixing disc.

  • Patent number: 11420657
    Abstract: A levelling system for a vehicle, in particular a rail vehicle, includes at least one levelling cylinder and a levelling piston. The levelling piston is at least partially provided in the levelling cylinder in a movable manner for setting the level of the rail vehicle. Further, the levelling system includes at least one guiding element, which is arranged within the levelling piston and partially protrudes from the levelling piston into at least one recess of the levelling cylinder such that an end stop in a longitudinal direction is provided for the relative movement between the levelling piston and the levelling cylinder.

  • Patent number: 7874254
    Abstract: A device for the secondary suspension of a body of a rail vehicle, the device comprising a spring element which is between the body and a bogie and to ensure at least one raised transport level for the body during the journey of the rail vehicle. The spring element can be compressed by a traction cylinder when the rail vehicle is stationary, in order to adjust a sunken platform level for the body, which is arranged below the raised driving level. The traction cylinder is provided with means for mechanically decoupling the advancing movement of the body from a pressure reduction in the pressure chamber of the traction cylinder.

  • Publication number: 20050183627
    Abstract: System for the secondary suspension of a superstructure (1) in the case of a rail vehicle, having a hydropneumatic spring unit (3) as an active spring element which is placed between the superstructure (1) and a bogie (2) arranged below it and which ensures at least one raised traveling level (NF) for the superstructure when the rail vehicle is traveling, by way of the hydropneumatic spring unit (3) as the active spring element, in the normal operation, in addition to the raised traveling level (NF), a lowered station platform level (NB) being adjustable for the superstructure (1), additionally at least one emergency spring cylinder (8) being provided which, when the system fails, ensures an emergency spring level (NN) situated in-between for an emergency operation.
