Accompanying drawing explanation
accompanying drawing 1 is structural representation of the present utility model.
wherein: 1, equilibrium arm; 2, hanger bracket; 3, hanging oil cylinder; 4, vehicle bridge; 5, tire; 6, wheel rim; 7, vehicle frame.
Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described:
the hydraulic suspension structure of a kind of low platform truck as shown in Figure 1, comprise be connected to hanger bracket 2 bottom platform truck vehicle frame 7, hanging oil cylinder 3, end that cylinder body is connected on hanger bracket 2 is connected to the equilibrium arm 1 on hanger bracket 2, the vehicle bridge 4 being connected to equilibrium arm 1 the other end and the wheel assembly be connected in vehicle bridge 4, the cylinder bar of hanging oil cylinder 3 is connected with equilibrium arm 1.
in the present embodiment: the material relating to steel structure in hydraulic suspension structure all adopts Q460C.The installation length of hanging oil cylinder 3 is 358mm, and stroke is 205mm, and when the cylinder body external diameter of hanging oil cylinder 3 remains unchanged substantially, cylinder shank diameter is increased to 140mm, and the little stroke of hanging oil cylinder 3 volume is large, and adds the thrust of hanging oil cylinder 3.The cylinder body of hanging oil cylinder 3 and the point of connection of hanger bracket 2 are 75mm to the distance of bottom of frame, and relatively existing distance improves 52mm; The cylinder bar of hanging oil cylinder 3 and the point of connection of equilibrium arm 1 are 210mm to the distance of the point of connection of hanger bracket 2 and equilibrium arm 1, relatively existing Distance Shortened 65mm, hanger bracket 2 and hanging oil cylinder 3 joint layout points compact and reasonable, so also coordinate hanging oil cylinder 3 thus make the nearly step-down of car low.The point of connection of vehicle bridge 4 and wheel assembly is 120mm to the distance between vehicle bridge 4 and the point of connection of equilibrium arm 1, and the axletree material of vehicle bridge 4 adopts 40Cr, improves the intensity of vehicle bridge 4.Wheel assembly comprises the wheel rim 6 be connected in vehicle bridge 4 and the tire 5 be connected on wheel rim 6, and the external diameter of tire 5 is 680mm; The external diameter of wheel rim 6 is 387mm, and adopts high strength material 245B.
be below the contrast of the present embodiment and prior art data:
