Description
Technical field:
The utility model relates to a kind of steel plate spring type front suspension No. three inhibiting device.
Background technology:
At present, on market, the inhibiting device of highway quarry tipper steel plate spring type front suspension mainly contains two kinds, is single limiting stopper inhibiting device and two limiting stopper inhibiting device respectively.Wherein, single limiting stopper inhibiting device field of application is the widest, though this kind of inhibiting device price is cheap, but limit effect is undesirable, particularly when the load capacity be subject to exceedes certain value, work owing to only having a limiting stopper, so very easily damage limiting stopper, service life is short, and damping effect is poor.Another kind of two limiting stopper inhibiting device, be equivalent to employ two single limiting stoppers, be hit load capacity shared on two limiting stoppers, though the inhibiting device price of this kind of structure is cheap, but shortage variation rigidity, traveling comfort is general, does not have mechanical rigid spacing when overload of vehicle is subject to greater impact, and two limiting stoppers are not enough to buffering, very easily cause the damage of limiting stopper, meanwhile, also there is the risk that antiarch excessively causes plastic deformation in leaf spring, causes leaf spring to damage the generation of phenomenon.
Utility model content:
The utility model provides a kind of steel plate spring type front suspension No. three inhibiting device; its structure is simple; reasonable in design; damping effect is strong; travelling comfort is better; effectively prevent the damage to limiting stopper when load capacity suffered by front suspension exceedes certain value; substantially prolongs the service life of limiting stopper; and the available protecting smooth-going anti-bow of leaf spring; avoid the risk of leaf spring plastic deformation, mechanicalness rigid limit, variation rigidity is strong; the service life of leaf spring can be extended, solve problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of steel plate spring type front suspension No. three inhibiting device, comprise a chassis side rail, the front frame be arranged on bottom chassis side rail is connected with the leaf spring two ends that after poppet is obliquely installed with respectively, upper end and the front frame bottom of leaf spring are hinged, hanger activity clamping on the lower end of leaf spring and after poppet bottom, be connected with automobile front-axle one axle head by a U-bolt in the middle part of leaf spring, the first limiting stopper is interval with successively from front to back bottom chassis side rail between front frame and after poppet, second limiting stopper and the 3rd limiting stopper, the bottom surface of the first limiting stopper is lower than the bottom surface of the second limiting stopper, the bottom surface of the first limiting stopper is higher than the bottom surface of the 3rd limiting stopper.
Described first limiting stopper and the 3rd limiting stopper are respectively rubber block.
Described second limiting stopper is rigid limit block, is provided with a layer of polyurethane bottom the second limiting stopper.
The utility model adopts such scheme; structure is simple, and reasonable in design, damping effect is strong; travelling comfort is better; effectively prevent the damage to limiting stopper when load capacity suffered by front suspension exceedes certain value, substantially prolongs the service life of limiting stopper, and the available protecting smooth-going anti-bow of leaf spring; avoid the risk of leaf spring plastic deformation; mechanicalness rigid limit, variation rigidity is strong, can extend the service life of leaf spring.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, 1, chassis side rail; 2, front frame; 3, after poppet; 4, leaf spring; 5, hanger; 6, U-bolt; 7, automobile front-axle; 8, the first limiting stopper; 9, the second limiting stopper; 10, the 3rd limiting stopper.
Detailed description of the invention:
For clearly demonstrating the technical characterstic of this programme, below by detailed description of the invention, and in conjunction with its accompanying drawing, the utility model is elaborated.
As shown in FIG., a kind of steel plate spring type front suspension No. three inhibiting device, comprise a chassis side rail 1, the front frame 2 be arranged on bottom chassis side rail 1 is connected with leaf spring 4 two ends that after poppet 3 is obliquely installed with respectively, upper end and front frame 2 bottom of leaf spring 4 are hinged, hanger 5 activity clamping on the lower end of leaf spring 4 and after poppet 4 bottom, be connected with automobile front-axle 7 one axle head by a U-bolt 6 in the middle part of leaf spring 4, the first limiting stopper 8 is interval with from front to back successively bottom chassis side rail 1 between front frame 2 and after poppet 3, second limiting stopper 9 and the 3rd limiting stopper 10, the bottom surface of the first limiting stopper 8 is lower than the bottom surface of the second limiting stopper 9, the bottom surface of the first limiting stopper 8 is higher than the bottom surface of the 3rd limiting stopper 10.
Described first limiting stopper 8 and the 3rd limiting stopper 10 are respectively rubber block.
Described second limiting stopper 9 is rigid limit block, bottom the second limiting stopper 9, be provided with a layer of polyurethane.Rigid limit block can play mechanical rigid position-limiting action, good damping effect, and the layer of polyurethane be arranged on bottom the second limiting stopper 9 can cushion the contact surface with leaf spring 4, reduces wear, increases the service life.
When vehicle deadhead operation, be arranged on the first limiting stopper 8 bottom chassis side rail 1 between front frame 2 and after poppet 3, second limiting stopper 9 and the 3rd limiting stopper 10 successively interval are arranged, 3rd limiting stopper 10, first limiting stopper 8 and the second limiting stopper 9 increase successively with the distance of leaf spring 4, when vehicle travels, automobile front-axle 7 loads the weight of about 6 tons, now leaf spring 4 camber change is relatively little, when vehicle run into concave-convex road surface cause vehicle to pitch time, because the 3rd limiting stopper 10 is nearest apart from leaf spring 4, therefore the 3rd limiting stopper 10 works, thus make the smooth-going increase of front suspension offset frequency of working, effectively can ensure the traveling comfort that unloaded personnel ride.
When the fully loaded traveling of vehicle; automobile front-axle 7 loads the weight of about 14 tons; now leaf spring 4 camber changes greatly; now the 3rd limiting stopper 10 contacts with leaf spring 4; when vehicle run into concave-convex road surface cause vehicle to pitch time; first limiting stopper 8 starts to work; contact with leaf spring 4; under the first two limiting stopper acts on simultaneously; leaf spring 4 load capacity can be shared; protection leaf spring 4 is not because there is plastic deformation and fracture in overload and impact, thus available protecting vehicle front suspension and leaf spring 4, effectively can ensure the traveling comfort that unloaded personnel ride.When vehicle is with the relatively high speed of a motor vehicle and when running into very large pit or thrust; vehicle front suspension can be subject to very large impact; automobile front-axle 7 can be subject to the enormous impact of 35 tons of heap(ed) capacities instantaneously; well beyond 20 tons of heap(ed) capacities of the maximum permission of leaf spring 4; now; the second limiting stopper 9 be arranged under chassis side rail 1 starts to work; when anti-bow is soon close to the maximum anti-bow amount allowed for leaf spring 4; second limiting stopper 9 contacts with leaf spring 4; leaf spring 4 is stoped to continue antiarch; actv. protection leaf spring 4, extends the service life of leaf spring 4.
Above-mentioned detailed description of the invention can not as the restriction to the utility model protection domain, and for those skilled in the art, any alternate modification make the utility model embodiment or conversion all drop in protection domain of the present utility model.
The utility model does not describe part in detail, is the known technology of those skilled in the art of the present technique.
