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.

An emergency air spring assembly includes an upper cover plate, an air bag, an upper end plate and a lower end plate. An outer periphery of the upper end plate is connected with an outer periphery of the lower end plate through the air bag. An hourglass elastomer is connected between the upper cover plate and the upper end plate. A plurality of steel springs are arranged between the upper cover plate and the upper end plate in a circumferential direction of the sand clock elastomer in a pressing mode.

An elastomeric bearing includes an inner member that has a spherical exterior surface and is symmetric about a central axis and a hollow annular outer structure that is axially split thereby forming a first outer segment and a second outer segment. The first outer segment and second outer segment form a substantially cylindrical exterior surface. One or more shim structures are formed around the inner member and are disposed at least partially inside the hollow annular outer structure. The shim structure has a radially outward facing surface and a radially inward facing surface. One or more layers of elastomeric material are disposed on each of the radially outward facing surface and the radially inward facing surface.

A level control system adjusting the level of a vehicle, particular a rail vehicle, and includes at least one level control cylinder and a level control piston, which is at least partially movably accommodated in the level control cylinder. Accordingly, the level control piston may have a substantially continuous outer diameter.

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 main tank storing pressurized air supplied to a pair of air springs; an air supply passage through which the pressurized air flows between the main tank and each of the pair of air springs; a plurality of compressors configured to supply the pressurized air to the main tank; an air discharge passage which is connected to the pair of air springs and through which discharged pressurized air discharged from the air springs flows; and an exhaust tank connected to the air discharge passage and storing the discharged pressurized air discharged from the air springs, the plurality of compressors including at least one first compressor configured to pressurize air introduced from an atmosphere and at least one second compressor configured to operate auxiliarily for an operation of the first compressor and pressurize the discharged pressurized air introduced from the exhaust tank.

A vehicle comprising: a vehicle body; a plurality of wheel assemblies each having a rotation axis; at least one suspension linkage, each suspension linkage coupling a respective wheel assembly to the vehicle body to permit motion of the rotation axis of each respective wheel assembly relative to the vehicle body; a damper coupled to a respective suspension linkage to constrain the motion of the associated wheel assembly by applying a damper reaction force to the suspension linkage, the damper being configured to be responsive to a damper force control output to vary the damper reaction force being applied to the suspension linkage; at least one vehicle sensor configured to provide vehicle condition data; and a damper control unit configured to generate the damper force control output that causes the damper to generate respective damper reaction forces to act against the suspension linkage to control the motion of the wheel assembly towards a set position for the wheel assembly relative to the vehicle body, adjust the set position based on a change in the vehicle condition data, and calculate the set position based on variations in the vehicle condition data over time.
