The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in the figure, a kind of agricultural superimposed trailer suspension gear, comprise: front frame (1), medium-height trestle (2) and after poppet (3) are installed on the vehicle frame (4) successively, be hinged with equalizing bar (5) at medium-height trestle (2), laminated spring assembly (6) is installed between front frame (1) and equalizing bar (5) and equalizing bar (5) and the after poppet (3), be provided with running axle stand (7) at the middle part of laminated spring assembly (6), each running axle stand (7) is connected and fixed by pipe link (8) with front frame (1) and the medium-height trestle (2) of front end, it is characterized in that: described front frame (1), medium-height trestle (2), after poppet (3) and equalizing bar (5) are foundry goods, laminated spring assembly (6) with before, after poppet (3) and equalizing bar (5) flexibly connect; Described equalizing bar (5) is hinged on the medium-height trestle (2) by hinge assembly (8); Laminated spring sheet (61) in the laminated spring assembly (6) is changeable section plate spring.
Preferably, described laminated spring assembly (6) is piled up by length variations by some laminated spring sheets (61) and forms, and fixes to clamp by running axle stand (7) and U-bolt (62), and laminated spring sheet (61) is each other owing to the variation in cross section leaves the space.
Preferably, described medium-height trestle (2) and equalizing bar (5) are provided with bipyramid hole (21), and two bipyramid holes (21) combination mutually are corresponding.
Preferably, described hinge assembly (8) is made of hinge (81), axle sleeve (83) and tapered hub (82), hinge (81) is located at heart portion, tapered hub (82) is socketed in the outside, axle sleeve (83) is socketed between hinge (81) and the tapered hub (82), and this tapered hub (82) cooperates socket with bipyramid hole (21) on medium-height trestle (2) and the equalizing bar (5).
