PNEUMATIC AXLE SUSPENSION FOR A REAR AXLE OF A VEHICLE

Pneumatic axle suspension (10) for a rear axle (12) of a vehicle, in particular a heavy goods vehicle, comprising spring beams (14) for supporting the axle (12), air bellows (18,20) arranged at the vehicle frame (16) to support the spring beams (14), a pair of hydraulic shock absorbers (22), a pair of front hangers (26) extending downwardly from the frame in front of the axle (12), longitudinal rods (28) extending between one front hanger (26) and one spring beam (14) and linked with its ends to the front hanger (26) and one spring beam (14), and a triangular rod (32) being pivotable linked to an upper center portion of the axle (12) and the frame (16), respectively. characterized by a stabilizer bar (44) which is generally U-shaped and disposed above the axle (12), with a traverse beam (46) and two legs (48,50) extending from the ends of the traverse beam (46) in a direction perpendicular to the axle (12), wherein the traverse beam (46) is rotatable supported within pivot bearings (52) mounted at the bottom of the frame (16) such that the legs (48,50) can perform a swiveling movement, and the ends (54) of the legs (48,50) being pivotable linked to the axle (12) via generally perpendicular thrust rods (56) and axle brackets (58), with each thrust rod (56) being pivotable hinged to one leg end (54) and to one axle bracket (58).
