Abstract
The utility model is related to technical field of engineering machinery, disclose a kind of hydraulic suspension, including fore-stock, leaf spring and oil cylinder, described fore-stock one end is weldingly fixed on crossbeam lower wing plate, the other end connects leaf spring by bearing pin, axletree is installed, described oil cylinder two ends connect crossbeam lower wing plate and leaf spring respectively on leaf spring.The utility model applicability is good, adjusts axletree height with the reduction of oil cylinder, it is ensured that the load-carrying of semitrailer, can lift tire when semitrailer is unloaded again, the abrasion of tire be reduced, while limit for height mark can also be smoothly passed over.
Description
Technical field
The utility model is related to technical field of engineering machinery, more particularly to a kind of hydraulic suspension.
Background technology
In the prior art, just only two kinds of the suspension that general semitrailer manufacturer installs：Mechanical suspension and air are outstanding
Hang, both suspension all existing defects, it is tire all landings that multi-spindle machining, which is suspended on zero load, tire still serious wear is empty
The defect of gas suspension is that loading capacity is little, thus needs a kind of Novel hung, can both reduce tire wear, and can not reduce again
Load-carrying load.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art there is provided a kind of hydraulic suspension, and its applicability is good, uses
The reduction regulation axletree height of oil cylinder, it is ensured that the load-carrying of semitrailer, tire can be lifted when semitrailer is unloaded, wheel is reduced again
The abrasion of tire, can also smoothly pass over limit for height mark.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of hydraulic suspension, including fore-stock,
Leaf spring and oil cylinder, described fore-stock one end are fixed on crossbeam lower wing plate, other end connection leaf spring, leaf spring and are provided with axletree,
Described oil cylinder two ends connect crossbeam lower wing plate and leaf spring respectively.
Further, fore-stock as described above is weldingly fixed on crossbeam lower wing plate.
Further, fore-stock and leaf spring as described above are connected by bearing pin.
Further, axletree is fixedly mounted in tail end in leaf spring as described above.
Further, axletree as described above is axially and oil cylinder is axially orthogonal.
Further, oil cylinder as described above could alternatively be cylinder.
Compared with prior art, the beneficial effects of the utility model are：The utility model is applicable all semitrailers, uses oil cylinder
Reduction regulation axletree height, it is ensured that the load-carrying of semitrailer, tire can be lifted, wheel is reduced when semitrailer is unloaded again
The abrasion of tire, while loading platform can also be lifted, when trailer is loaded with goods, during by some limit for height bridge bottoms, hydraulic suspension can
So that trailer to be reduced, it is ensured that trailer passes through.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Mark in accompanying drawing for：1. fore-stock；2. bearing pin；3. leaf spring；4. axletree；5. oil cylinder；6. crossbeam lower wing plate.
Embodiment
It is described in detail referring to the drawings with reference to embodiment, to enter to technical characteristic of the present utility model and advantage
Row deeper into annotation.
As shown in figure 1, a kind of hydraulic suspension of the present utility model, including fore-stock 1, leaf spring 3 and oil cylinder 5, it is described before
The one end of support 1 is weldingly fixed on crossbeam lower wing plate 6, and the other end connects leaf spring 3 by bearing pin 2, and the tail end of leaf spring 3 is fixedly mounted
Axletree 4, the described two ends of oil cylinder 5 connect crossbeam lower wing plate 6 and leaf spring 3 respectively.Further, the axial direction of axletree 4 and the axial direction of oil cylinder 5
Orthogonal, oil cylinder 5 may be replaced by cylinder.
Operating principle of the present utility model is as follows:When oil cylinder is 5 liters long, vehicle rise；When oil cylinder 5 shortens, under vehicle
Drop.In the reduction of oil cylinder 5 so that bearing pin 2 of the leaf spring 3 on fore-stock 1 is rotated, and axletree 4 also becomes therewith on leaf spring 3
Change, the lifting of axletree 4 causes the lifting of tire, so that the height of vehicle changes therewith, can conveniently pass through limit for height mark.
And for multiaxis oil cylinder 5, can partly be lifted, such trailer on the way deadhead operation when, it is possible to lift multiaxis and avoid contact with
Road surface, only retains axle traveling, reduces the tire wear during zero load of other axles.
Clear, complete description is carried out to the utility model by the technical scheme in above example, it is clear that described
Embodiment be the embodiment of the utility model part, rather than whole embodiment.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
