Description
Technical field
The utility model relates to the suspension system of vehicle, specifically the associated mode hydraulic suspension of a kind of trailer or superimposed trailer.
Background technology
At present, some is swing arm type (mono-pendulum type or double pendulum type) for existing hydraulic suspension, hydraulic ram connects with wheel shaft by swing arm, the swing arm type hydraulic suspension mainly is used on heavy type and the superduty trailer, but because of its manufacturing cost and use cost height, from great, thereby rarely have and be used on common trailer or the superimposed trailer.Common trailer or superimposed trailer adopt Leaf spring suspension or air spring suspension more, but the superimposed trailer that adopts Leaf spring suspension or air spring suspension can not well satisfy the traffic requirements of some particular cargos, transportation as blade and the cabin of wind-power electricity generation, and adopt the problem that the swing arm type hydraulic suspension is made and use cost is high very outstanding, need improve.
Summary of the invention
The purpose of this utility model provides the associated mode hydraulic suspension of a kind of trailer or superimposed trailer, and its use cost is low, and can satisfy the transportation request of some particular cargos.
To achieve these goals, the utility model adopts following technical scheme: comprise axletree and vehicle frame, it is characterized in that: be provided with mobile guide mechanism between described axletree and the vehicle frame, the upper end of the inboard of described axletree is interval with two oil cylinder front end Connection Blocks, the cross member of frame two ends of vehicle frame are provided with oil cylinder rear end Connection Block, are provided with hydraulic ram between oil cylinder front end Connection Block and oil cylinder rear end Connection Block.
In technique scheme, when the trailer that this hydraulic suspension is housed or superimposed trailer during by uneven road surface, hydraulic ram can be stretched or contract automatically, thereby makes trailer or each axle load of superimposed trailer self-equalizing, and its equilibrium principle is with the normal air suspension; Simultaneously, because the utility model is equipped with mobile guide mechanism, when axletree during by the bigger road surface of upper and lower difference in height, mobile guide mechanism can guarantee that trailer or superimposed trailer are also can transport some particular cargos by pulsation-free at uphill/downhill.
In technique scheme, described mobile guide mechanism comprises pilot bar 6, and cross member of frame 10.1 is provided with guide groove 5, and the centre of axletree 9 inboards is provided with pilot bar Connection Block 4; The upper end of pilot bar 6 is connected with guide groove 5, and the lower end of pilot bar 6 is connected with pilot bar Connection Block 4.When axletree passes through the inconsistent road surface of upper and lower height, one of them of hydraulic ram on the same axletree can be stretched, another can contract, axletree just has the trend generation of rotation like this, yet the commentaries on classics heart of axletree is at pilot bar Connection Block hinge hole center, thereby realization trailer or the superimposed trailer automatic guide when mobile.
In technique scheme, described axletree is provided with and prevents rotation seat, and the frame beam lower end of vehicle frame is provided with the axletree mount pad, and the described rotation seat that prevents is connected in the axletree mount pad.When axletree prevent that rotation seat is arranged in the axletree mount pad after, the tractive force on the vehicle frame is delivered on the axletree by the axletree mount pad, thereby makes axletree produce relative motion; Simultaneously, owing to prevent that rotation seat from can only move up and down in the axletree mount pad, thereby make the axletree also can only up-and-down movement, overcome thereby the moment of torsion that produces when making the braking of axletree Z-direction is prevented from rotation seat.

The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute restriction to the utility model, only do for example.Simultaneously by illustrating that advantage of the present utility model will become clear more and understanding easily.
Consult accompanying drawing as can be known: comprise axletree 9 and vehicle frame 10, it is characterized in that: be provided with mobile guide mechanism between described axletree 9 and the vehicle frame 10, the upper end of the inboard of described axletree 9 is interval with two oil cylinder front end Connection Blocks 1, cross member of frame 10.1 two ends of vehicle frame 10 are provided with oil cylinder rear end Connection Block 3, are provided with hydraulic ram 2 between oil cylinder front end Connection Block 1 and oil cylinder rear end Connection Block 3.
When the trailer that this hydraulic suspension is housed or superimposed trailer during by uneven road surface, hydraulic ram 2 can be stretched or contract automatically, thereby makes trailer or each axle load of superimposed trailer self-equalizing, and its equilibrium principle is with the normal air suspension; Simultaneously, because the utility model is equipped with mobile guide mechanism, when axletree during by the bigger road surface of upper and lower difference in height, mobile guide mechanism can guarantee that trailer or superimposed trailer pulsation-free transport some particular cargos.
Described mobile guide mechanism comprises pilot bar 6, and cross member of frame 10.1 is provided with guide groove 5, and the centre of axletree 9 inboards is provided with pilot bar Connection Block 4; The upper end of pilot bar 6 is connected with guide groove 5, and the lower end of pilot bar 6 is connected with pilot bar Connection Block 4.About an axletree passes through highly during inconsistent road surface, one of them can stretch two hydraulic rams 2 on the same axletree, and another can contract, and axletree will rotate like this, and it changes heart at pilot bar Connection Block 4 hinge hole centers.Because the utility model is provided with pilot bar 6, thereby make the structural stability of hydraulic suspension higher, and because the center of axletree always overlaps with the longitudinal center of vehicle frame, and tire can inordinate wear during use, thereby make the bad more usefulness of tire of hydraulic suspension.
In technique scheme, described axletree 9 is provided with and prevents rotation seat 8, and frame beam 10.2 lower ends of vehicle frame are provided with axletree mount pad 7, and the described rotation seat 8 that prevents is connected in the axletree mount pad 7.When axletree 9 prevent that rotation seat 8 is arranged in the axletree mount pad 7 after, the tractive force on the vehicle frame 10 is delivered on the axletree 9 by axletree mount pad 7, thereby makes axletree 9 produce relative motions; Simultaneously, owing to prevent that rotation seat 8 from can only move up and down in axletree mount pad 7, thereby make the axletree 9 also can only up-and-down movement, overcome thereby the moment of torsion that produces when making axletree 9Z to braking is prevented from rotation seat 8.
Above-mentionedly a complete hydraulic suspension, i.e. the associated mode hydraulic suspension of trailer or superimposed trailer have just been constituted.Because its axletree adopts the sort of axletree of common trailer or superimposed trailer or turns to axletree, therefore adopt the trailer of this hydraulic suspension or superimposed trailer tire the same with common trailer or superimposed trailer, its use cost is low.
Other not specifically described parts are prior art.
