The invention relates to a cross member for articulating a body of a rail vehicle to the bogie thereof; the upper face of the cross member is connected to the body, and a bogie pin-supporting plate comprising a bogie pin is secured to the lower face of the cross member with the aid of fastening means, the bogie pin being movably mounted in a bogie pin receptacle on the bogie in order to transmit pulling and braking forces.

A bearing for mounting an anti-roll bar on a bogie frame, the anti-roll bar extending along an axis transverse to the bogie and being mobile in rotation relatively to the frame around the axis, the bearing including a first half-shell, and a second half-shell adapted so as to be attached on the first half-shell by means of a first attachment system, the first half-shell and the second half-shell then forming a housing crossing through along the axis and adapted for receiving the anti-roll bar. The first half-shell is distinct from the frame and adapted so as to be attached on the frame by means of a second attachment system.

A railway truck includes two parallel side frames, a suspension spring assembly supported by the side frames, and a bolster transversely mounted between the side frames and supported by the suspension spring assembly. Each side frame has at least one vertical support face, and the bolster has at least one sloped support face. A friction shoe includes a bottom base engaging and supported by a support spring, and a sloped wall engaging the sloped support face of the bolster. The friction shoe prevents bolster side wall wear.

In a method for stabilizing a rail vehicle with a wheel set, the speed of the rail vehicle is changed when a critical vibration state of the wheel set occurs. An advantageous state can be achieved if the speed of the rail vehicle is changed by using a vibration state variable of the wheel set.
