A wheel axle guiding assembly (31) for a running gear (10) of a rail vehicle, comprises: an axle box assembly (30), a support assembly (24) and a hydro-mechanical guiding assembly (26) fixed to the axle box assembly (30) and to the support assembly (24) to allow a fore-and-aft movement of the axle box assembly (30) relative to the support assembly (24). The hydro-mechanical guiding assembly (26) comprises: a first variable volume hydraulic chamber (38A) and a second variable volume hydraulic chamber (38B) between the support assembly (24) and the axle box assembly (30) such that a movement of the axle box assembly (30) relative to the support assembly (24) in the steering direction (300) results in a reduction of an internal volume of the one of the first and second variable volume hydraulic chambers (38A, 38B) and a corresponding increase of an internal volume of the other of the first and second variable volume hydraulic chambers (38A, 38B). The hydro-mechanical guiding assembly (26) further comprises load-dependent pressurising means (42) such that an increase in a vertical load applied by the support assembly (24) on the axle box assembly (30) results in an increase of pressure into the first variable volume hydraulic chamber (38A) and second variable volume hydraulic chamber (38B).
