The invention relates to a wheel axle guiding assembly comprising an axle box carrier, an axle box located longitudinally between a front part and a rear part of the axle box carrier; a front longitudinal hydro-mechanical converter between a front part of an axle box carrier and a rear longitudinal hydro-mechanical converter between the axle box and a rear part of the axle box carrier to allow a fore-and-aft movement of the axle box relative to the axle box carrier parallel to a longitudinal direction. Each of the front and rear longitudinal hydro-mechanical converters includes a housing, a plunger and an elastomeric body fixed to the housing and to the plunger so as to allow a fore-and-aft relative movement parallel to the longitudinal direction between the plunger and the housing, a single variable volume hydraulic chamber being formed between the housing, the plunger and the elastomeric body.
