Abstract
A kind of build-up type balance shaft suspension gear, comprise two symmetrically arranged trunnion bases, each trunnion base is connected by bolt with the outer surface of corresponding chassis side rail and crossbeam lower surface respectively, in trunnion base, balance shaft is installed, between two trunnion bases, be provided with one be positioned at bearing tie-beam below crossbeam, the top, two ends of bearing tie-beam is connected with two trunnion bases respectively by tie bolt, is connected bottom the two ends of bearing tie-beam respectively by fixed pin shaft with bottom two trunnion bases.Its reasonable in design, thoroughly solves rivet by the fault of cutting off, shortens the time-to-market of new product, reduce the manufacturing cost of product.
Description
Technical field:
The utility model relates to a kind of build-up type balance shaft suspension gear.
Background technology:
Highway quarry tipper during operation, can produce and compare heavy shock loads on rugged highway road surface, and impact load is delivered to balance shaft by steel spring and hangs.At present, balance shaft hangs as inblock cast structure, is connected with vehicle frame by midship mounting, and midship mounting and cross member of frame and side connecting plate are fixed together by rivet.In vehicle operation, the rivet of fixing midship mounting is comparatively large by shearing, and rivet is often cut off under alternation shearing action over a long time, has delayed normal production, for company and client cause no small economic loss.In addition, in the development process of new product, the product of different tonnage, frame width is not identical yet, will readjust the width of balance shaft suspension like this, thus adding the input cost of mould, and increasing the R&D cycle simultaneously yet to adapt to frame width.
Summary of the invention:
The utility model is in order to make up the deficiencies in the prior art, provide a kind of build-up type balance shaft suspension gear, its reasonable in design, thoroughly solve rivet by the fault of cutting off, shorten the time-to-market of new product, reduce the manufacturing cost of product, 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 build-up type balance shaft suspension gear, comprise two symmetrically arranged trunnion bases, each trunnion base is connected by bolt with the outer surface of corresponding chassis side rail and crossbeam lower surface respectively, in trunnion base, balance shaft is installed, between two trunnion bases, be provided with one be positioned at bearing tie-beam below crossbeam, the top, two ends of bearing tie-beam is connected with two trunnion bases respectively by tie bolt, is connected bottom the two ends of bearing tie-beam respectively by fixed pin shaft with bottom two trunnion bases.
The utility model adopts such scheme, reasonable in design, comprise the cast type trunnion base at two ends and middle bearing tie-beam, eliminate midship mounting and the connection rivet of original design, thoroughly solve rivet by the fault of cutting off, simultaneously for the product of different frame width, only need the bearing tie-beam in the middle of changing, the trunnion base at two ends does not need die sinking again again, simplify processing technology thereof and assembly technology, shorten the time-to-market of new product, reduce the manufacturing cost of product, improve the competitive power of product.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure, 1, trunnion base, 2, chassis side rail, 3, crossbeam, 4, balance shaft, 5, bearing tie-beam, 6, tie bolt, 7, fixed pin shaft.
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 Figure 1, a kind of build-up type balance shaft suspension gear, comprise two symmetrically arranged trunnion bases 1, each trunnion base 1 is connected by bolt with the outer surface of corresponding chassis side rail 2 and crossbeam 3 lower surface respectively, balance shaft 4 is installed in trunnion base 1, between two trunnion bases 1, be provided with one be positioned at bearing tie-beam 5 below crossbeam 3, the top, two ends of bearing tie-beam 5 is connected with two trunnion bases 1 respectively by tie bolt 6, is connected bottom the two ends of bearing tie-beam 5 respectively by fixed pin shaft 7 with bottom two trunnion bases 1.
Adopt build-up type balance shaft suspension gear of the present utility model, trunnion base 1 and chassis side rail 2 outer surface, crossbeam 3 lower surface are bolted, power from the vertical direction of balance shaft 4 is directly passed to chassis side rail 2 and crossbeam 3, transverse force is transmitted by bearing tie-beam 5, make two chassis side raiies 2 and crossbeam 3 simultaneously stressed, the rivet avoiding original design is cut, the force-bearing situation of Optimization Balancing axis suspension.Bearing tie-beam 5 is connected with trunnion base 1 by fixed pin shaft 7 and tie bolt 6, and the transverse distance of bearing tie-beam 5 can regulate according to frame width, improves process for machining and manufacturing, reduces manufacturing cost.
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.
