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 locomotive suspension system includes a truck frame coupled with a locomotive body frame by one or more upper suspensions and a first motor suspension coupled with a first motor and the truck frame. The first motor is coupled with a first axle of the truck frame. The locomotive suspension system also includes a second motor suspension coupled with a second motor and the truck frame. The second motor is coupled with a second axle of the truck frame. The first and second motor suspensions are asymmetrically arranged on opposite sides of a bisecting plane of a truck wheelbase of the truck frame. The truck wheelbase extends from the first axle to the second axle along a length of the truck frame.

A carbody of a railcar includes: a roof bodyshell; a supporting body provided under the roof bodyshell, the supporting body being attached to the roof bodyshell in a state of being positioned in the vertical direction; a rotating body which is threadedly engaged with the supporting body and rotates relative to the supporting body about an axis extending in a vertical direction to be displaced relative to the supporting body in the vertical direction; and a support target member supported by the roof bodyshell through the supporting body and the rotating body, the support target member being attached to the rotating body in a state of being positioned in the vertical direction, a vertical distance between the roof bodyshell and the support target member being adjustable by displacement of the rotating body relative to the supporting body.

A device for connecting a cross member for receiving pivot pins on two lower longitudinal members of a car body for a rail vehicle. The cross member has a transversal part that connects the two longitudinal members to each other in the region of the connection, and a longitudinal part that extends to the closest car front. The lower longitudinal members extend over the complete length of the car body and consist of multi-chamber hollow profiles made of a fibre composite material. The number of chambers of the multi-chamber hollow profile of each longitudinal member is reduced in the region of the connection such that the wall material of at least one chamber was removed in such a way that the webs to the adjacent chambers are exposed. At these places, load-introducing elements engage, to which load-introducing elements the cross member is attached.

A railcar includes: an underframe including a pair of side sills and a plurality of cross beams each connected to the pair of side sills, the cross beams being arranged at intervals in a car longitudinal direction; and a floor pan arranged in a space surrounded by the pair of side sills and a pair of adjacent cross beams among the plurality of cross beams, the floor pan being fixed to the underframe, the floor pan being configured as a strength member configured to bear at least one of a compressive load and shearing load applied from the underframe.

The invention relates to a railway vehicle comprising a car (14) and a bogie (16). The bogie (14) comprises a chassis (28) and a secondary suspension system (30). The secondary suspension system (30) comprises: a set (34) of springs; a jack (36) comprising two ends (44, 46); and a supply device (38) of the jack (36).

The jack (36) is configured to go from a first so-called retracted configuration in which the jack (36) is only connected to the car (14) by the first end (44) to a second so-called deployed configuration in which the jack (36) is also connected to the chassis (18) by the second end (16).

The power supply device (38) is configured, in the deployed configuration, to supply the jack (36) so as to move the car (14) away from the chassis (28) or to keep the distance between the car (14) and the chassis (28) constant.
