The invention relates to a wheel axle guiding assembly (10) comprising an axle box carrier (20), an axle box (14) located longitudinally between a front part (16) and a rear part (18) of the axle box carrier (20); a front longitudinal hydro-mechanical converter (32) between a front part (16) of an axle box carrier (20) and a rear longitudinal hydro-mechanical converter (34) between the axle box (14) and a rear part (18) of the axle box carrier (20) to allow a fore-and-aft movement of the axle box (14) relative to the axle box carrier (20) parallel to a longitudinal direction (200). Each of the front and rear longitudinal hydro-mechanical converters (32, 34) includes a housing (36), a plunger (38) and an elastomeric body (40) fixed to the housing (36) and to the plunger (38) so as to allow a fore-and-aft relative movement parallel to the longitudinal direction (200) between the plunger (38) and the housing (36), a single variable volume hydraulic chamber (42) being formed between the housing (36), the plunger (38) and the elastomeric body (40). A hydraulic port (54) provides a connection of the variable volume hydraulic chamber (40) with an external hydraulic circuit (54, 56, 64, 66, 68, 70, 72, 74).
