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.

A level control system adjusts the level of 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 system has at least one first hydraulic connection, wherein the level control cylinder or the level control piston has a collared shoulder, in which at least one first fluid channel connected to the first hydraulic connection is arranged. At least one first attachment for receiving the first hydraulic connection is provided along the collared shoulder, the first attachment, being arranged on the collared shoulder tangentially to the longitudinal axis of the level control cylinder or of the level control piston such that at least one tangential external fluid connection on the collared shoulder can be connected to the at least one first hydraulic connection.

A level control system for a vehicle, in particular a rail vehicle, includes at least one level control cylinder and one level control piston, the level control piston being movably guided in the level control cylinder in order to adjust the level of the rail vehicle, the level control piston having an outer piston sleeve and a piston main body at least partially accommodated in the piston sleeve, and the piston main body being slidable relative to the piston sleeve for wear readjustment and being lockable and/or fixable in at least two adjustment positions.

A chassis suspension (10) for rail vehicles (36), the chassis suspension including a carriage body (12) which is supported on a chassis (16) via a spring system (18), the chassis suspension (10) having an anti-lift device (24) with a stop element (30) fixed in respect to the carriage body (12) and a stop element (28) fixed in respect to the chassis (16), between which stop elements free play exists which limits the rebound travel of the spring system (18) if the carriage body (12) is raised, and a level adjustment device for the carriage body (12) is formed by an extendable actuator (34) positioned between the two stop elements (28, 30).

A method controls the height of a floor of a car of a vehicle relative to a platform. The car includes a body provided with a distance sensor, at least one bogie and at least one secondary suspension between the bogie and the body. The method includes measuring the distance between the distance sensor and the platform via the distance sensor, calculating the difference between the height of the platform and the height of the floor from the measured distance, and adjusting the height of the secondary suspension based on the difference.
