And arranged on left and right sides is provided with four longitudinal rods, and an end of every longitudinal rod is connected the middle part of both sides arched beam, and its other end is connected the lower end of longitudinal thrust shaft bar, and the upper end of this longitudinal thrust shaft bar is fixedly connected on the outside, middle part of vehicle frame;
Panhard rod takes the shape of the letter U, divide two front and rear portions that are arranged in vehicle frame, the two ends of each stabilizer rod are rotatably connected on suspension rod lower end, both sides, this suspension rod upper end is fixedly connected on the outside of vehicle frame by the stabilizer rod carriage, the U-shaped two bottom sides of stabilizer rod is rotationally connected with the stabilizer rod connecting panel respectively, and this stabilizer rod connecting panel is separately fixed on the arched beam middle part, both sides;
The two ends of every arched beam are fixedly equipped with two air bag assemblies respectively, and the vehicle frame both sides have eight air bag assemblies, captive joint with the outside of vehicle frame by air bag assembly upper cover plate in this air bag assembly top;
Be connected with a shock absorber on the every arched beam respectively, the vehicle frame both sides have eight shock absorbers, and the upper end of this shock absorber is fixedly connected on one and is fixed on the damper bracket in the vehicle frame outside.
The utility model is owing to adopted technique scheme, road-holding property and cargo transportation security had both been kept, overcome the weakness of combined type air suspension anti-roll capability difference again, improved roll rate simultaneously, its anti-roll capability is suitable with the leaf spring suspension, makes the vehicle safety in travelling obtain guarantee.The utility model is applicable to two rear-axle drive suspensions of heavy-duty truck.
