FIELD: transport machine building.

SUBSTANCE: invention relates to axle suspensions. Axle suspension for controlled rigid axles comprises two longitudinal and four-point levers. Longitudinal levers are located at the same height on both sides of longitudinal axis and pass in longitudinal direction of vehicle, axle is bridged in vertical direction with body. Four-point lever is hingedly connected on one side with axle, on the other side—with vehicle body, located under longitudinal levers.
