Axle suspension for rigid axles of vehicles

An axle suspension for rigid axles of vehicles and vehicle chassis, the axle suspension and chassis comprising:

• a vehicle chassis with longitudinal frame members arranged at laterally spaced locations from one another, said longitudinal frame members being firmly connected to each other via crossbeams;
• a support bracket connected to a middle portion of one of said crossbeams and extending downward in a vertical direction to a support bracket lower end;
• a four-point connecting rod with a first two joint connection above the vehicle axle to the vehicle axle and with a second two joint connection above the vehicle axle directly connecting the four-point connecting rod to the vehicle chassis, said first two joint connection being arranged at a spaced location from said second two joint connection;
• a first spring assembly on a first vehicle side located for spring suspension between the vehicle axle and the vehicle body;
• a second spring assembly on a second vehicle side located for spring suspension between the vehicle axle and the vehicle body;
• and
• an axle strut for axle guiding, said axle strut extending in the longitudinal direction of the vehicle substantially centrally with respect to said first vehicle side and said second vehicle side and connecting the vehicle axle to the support bracket lower end in a vertically movable manner.

An air-cushioned utility vehicle axle, axle suspension and vehicle chassis combination, the combination comprising:

• a rigid vehicle axle;
• a vehicle chassis with longitudinal frame members arranged at laterally spaced locations from one another, said longitudinal frame members being firmly connected to each other via crossbeams;
• a support bracket connected to a middle portion of one of said crossbeams and extending in a vertical direction downwardly to a support bracket lower end;
• a twistable four-point connecting rod connected to a top of the vehicle axle via two joints and connected directly to the vehicle chassis via two joints, said joints for each connection being arranged at spaced locations from one another in a longitudinal direction of the vehicle;
• a first side spring assembly unit for spring suspension between the vehicle axle and the vehicle body;
• a second side spring assembly unit for spring suspension between the vehicle axle and the vehicle body;
• and
• an axle strut for axle guiding, said axle strut extending below the axle approximately in a vehicle middle and in a vehicle longitudinal direction and connecting the vehicle axle to said support bracket lower end in a vertically movable manner.
