Description
Technical field
The utility model belongs to technical field of traffic transportation, specifically, relates to a kind of suspension gear of superimposed trailer.
Background technology
The superimposed trailer suspension gear is one of major part of superimposed trailer, and it mainly acts on is superimposed trailer axletree movable parts and superimposed trailer crossbeam effectively and reasonably, be tied securely.The suspension gear of public superimposed trailer, suspension holdfast is welded on superimposed trailer main longitudinal grider lower end, the end of steel spring assigns in the suspension holdfast, the middle part is connected by the axletree of " U " shape bolt with its below, and the load of bearing on the vehicle body passes to steel spring by suspension holdfast and passes on the axletree again; One side of axletree is connected with an adjacent spring carrier by tension bar, is used for bearing horizontal force.Adopt the superimposed trailer of this suspension gear, as the wheel that has of wheel kiss the earth when unsettled, the phenomenon that whole load of superimposed trailer are only born by the wheel of kiss the earth will appear, this superimposed trailer if when lade at the uneven road traveling that jolts, because wheel is unsettled inevitable, thereby very easily causes wheel, axletree and steel spring to damage because of exceeding its strength limit.
China's utility model patent specification sheets discloses " suspension gear of superimposed trailer " (notification number CN 201065056Y of the applicant on May 28th, 2008, application number 200720126993.2), this patent is welded on spring carrier the top of vehicle bridge, be respectively equipped with slotted eye at propons spring carrier and back axle spring carrier bottom, the bottom of steel spring is provided with the folding hook, and this folding hook is hooked on respectively in the slotted eye of described propons and back axle spring bracket; On carrier base, carrier base is installed in middle part, suspension holdfast upper end and the welding of semi-trailer frame crossbeam of steel spring with " U " shape bolt by pivot knuckles in the suspension holdfast bottom.Use the superimposed trailer of this suspension gear, as the wheel that has of wheel kiss the earth when unsettled, under the spring force effect of steel spring, steel spring can be around the pivot rotation of hinged suspension holdfast and carrier base, driving unsettled wheel active kiss the earth is that superimposed trailer provides support power, use the superimposed trailer of this suspension gear,, also can not cause disconnected spring, off-axis because of wheel is unsettled, blow out even when fully loaded with cargo, travel on the uneven road surface of jolting.Find in the use, this patent invar laminated spring is to be connected with spring carrier by the folding hook, and have the following disadvantages: if a folding hook is connected not tight with spring carrier or the fracture of folding hook, the steel spring obscission will appear, cause that vehicle bridge, tire break away from, displacement, might produce disconnected spring, off-axis, blow out, consequence such as overturning.Two, because folding is hooked in the bigger gap of existence when being connected with slotted eye, installation error in addition, might cause vehicle bridge and vehicle crossbeam to present the out of plumb state, cause tire in rolling process, on same direction not cause that with working direction the tire phenomenon appears gnawing in Abnormity abrasion about tyre.
Summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned patent exists, and a kind of suspension gear of superimposed trailer is provided, this suspension gear can more effectively prevent superimposed trailer break spring, off-axis, blow out, can avoid gnawing the generation of tire phenomenon again.
For achieving the above object, the suspension gear of the utility model superimposed trailer comprises suspension holdfast, vehicle bridge, spring carrier, steel spring, the suspension holdfast lower end by pivot knuckles on carrier base, carrier base is installed in the middle part of steel spring with " U " shape bolt, spring carrier welds or is bolted to " U " shape the top of vehicle bridge, rear portion at front spring spring bracket and light plate spring bracket, and the front portion of rear leaf spring support is provided with pin shaft hole, the front end of the below spring plate of front spring spring and rear leaf spring, and the rear end of the below spring plate of rear leaf spring is provided with pin shaft hole; Front spring spring front end is installed on the front spring spring bracket by bearing pin, and the rear end assigns in the light plate spring bracket; The rear leaf spring front end is installed on the light plate spring bracket with bearing pin, and the rear end is installed on the rear leaf spring support with bearing pin.
The utility model in aforementioned patent number is on 200720126993.2 the patent basis, the folding hook of original steel spring is connected to change into bearing pin connect.Compare because the bearing pin connection is connected with the folding hook, contact surface is big, bearing surface is big, and structure is more reasonable, and the possibility of connecting portion fracture is very little; In addition because steel spring is to be installed on the spring carrier by bearing pin, the axial intermittence of bearing pin and pin shaft hole is very little, the connection location of steel spring is determined easily, be easy to avoid installation error, therefore the utility model can more effectively prevent the break generation of spring, off-axis, the phenomenon of blowing out of superimposed trailer, can avoid again gnawing the tire phenomenon because of what vehicle bridge and vehicle crossbeam presented that the out of plumb state causes.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a birds-eye view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described.
As shown in Figure 1 and Figure 2, spring carrier 8,11,6 welds or is bolted to " U " shape the top of vehicle bridge 7,10,13, be provided with pin shaft hole (left is preceding among the setting figure) at front spring spring bracket 8 rear portions, the front end of the below spring plate of front spring spring 15 is provided with pin shaft hole; Front spring spring 15 front ends are installed on the front spring spring bracket 8 by bearing pin 1, and the rear end assigns in the light plate spring bracket 11.Front portion at light plate spring bracket 11 rear portions and rear leaf spring support 6 is provided with pin shaft hole equally, and the front and back end of the below spring plate of rear leaf spring 16 all is provided with pin shaft hole; Rear leaf spring 16 front ends are installed on the light plate spring bracket 11 with bearing pin 3, and the rear end is installed on the rear leaf spring support 6 with bearing pin 5.Suspension holdfast 2,4 lower ends by pivot knuckles on carrier base 9,12; Carrier base 9,12 usefulness " U " shape bolts are installed in the middle part of steel spring 15,16, and steel spring can be rotated around described center shaft.The pin shaft hole of spring plate end can be formed by the grasswort that the steel plate end folds.
The utility model is identical with the connection mode and the prior art of superimposed trailer, also is suspension holdfast 2,4 is welded or be fixed by bolts to superimposed trailer main longitudinal grider 14 lower ends.Compare with communal technique, the utility model structure is more simple, is example with graphic three superimposed trailers, communal technique four groups of suspension holdfasts of needs and three pairs of tension bars, and the utility model is without tension bar, two groups of suspension holdfasts of needs.
This Figure of description only shows the suspension gear of three common superimposed trailers, and obviously, the technical solution of the utility model also can be used for superimposed trailer and the another kind of at present two common superimposed trailers more than three.
