Abstract
The utility model discloses the utility model is a kind of multiaxis heavily card air-suspension bellows load sensing valve regulating mechanism adopting air suspension, comprise the pipe link one and pipe link two that are flexibly connected with adjacent vehicle bridge respectively, the other end of pipe link one and the other end of pipe link two hinged, pipe link two stage casing is connected with montant, the montant other end is connected with cross bar, the cross bar other end is connected with load sensing valve, and load sensing valve is arranged on vehicle frame.Wherein, adjacent vehicle bridge is respectively arranged with fixed support one and fixed support two, and fixed support one and fixed support two are connected to ball end, and pipe link one and pipe link two are flexibly connected with vehicle bridge by ball end; Montant two ends are provided with rubber coating, and montant connects pipe link two stage casing and cross bar by rubber coating.The beneficial effect of this programme can be learnt according to describing of such scheme, and structure is simple, reasonable in design, and the stability of load sensing valve mechanism and reliability are significantly strengthened.
Description
Technical field
The utility model relates to one heavily card parts, particularly relates to a kind of multiaxis heavily card air-suspension bellows load sensing valve regulating mechanism adopting air suspension.
Background technology
Along with the development of construction trade, large-scale concrete pump truck is more and more subject to the favor of user, particularly when the one-time-concreting of, ultra-large volume large in concreting demand and super thick base concrete and the high engineering of requirements for quality, large-sized concrete pump truck is only selection.Due to large-scale pump truck axletree One's name is legion, be generally more than four axles, major part is five axles, in order to ensure that load-carrying capacity reduces costs again as far as possible simultaneously, three, four axles of five axle pump trucks are axle drive shaft and are leaf spring type balance suspension, and the 5th axle is pivot shaft and is air suspension.For ensureing the matching relationship of the 5th axle air suspension and three, four axle suspension height, the inflation/deflation of five axle air-suspension bellowss must be controlled by the suspension height of three, four bridges by load sensing valve, otherwise can cause that three, four axle propulsive efforts are not enough, the 5th axle transships the even phenomenon such as balloon burst.But the pipe link one of current load sensing valve regulating mechanism and pipe link two adopt hinged connection mode with vehicle bridge, when vehicle travels in bad road conditions, the twisting of vehicle bridge can make load sensing valve regulating mechanism leverage produce stress and then reduce life and reliability; The montant of load sensing valve regulating mechanism current in addition and the connection mode of pipe link two and cross bar are also hinged, frequently can be subject to the physical shock that vehicle vibration causes, and easily cause hinge to occur catching phenomenon by vehicle bottom because of silt pollution, make load sensing valve mechanism slow in reacting.
Utility model content
The utility model is for the deficiency existing for prior art, and it is simple, reasonable in design to provide a kind of structure, the multiaxis heavily card air-suspension bellows load sensing valve regulating mechanism of the employing air suspension that stability and reliability are strengthened.
To achieve these goals, the utility model provides a kind of multiaxis heavily card air-suspension bellows load sensing valve regulating mechanism adopting air suspension, comprise the pipe link one and pipe link two that are flexibly connected with adjacent vehicle bridge respectively, the other end of described pipe link one is connected with the other end of described pipe link two, described pipe link two stage casing is connected with montant, the described montant other end is connected with cross bar, the described cross bar other end is connected with load sensing valve, described load sensing valve is arranged on vehicle frame, comprise the ball end be connected with adjacent vehicle bridge respectively, described pipe link one and pipe link two are flexibly connected with described vehicle bridge by described ball end, described montant two ends are provided with rubber coating, and described montant connects described pipe link two stage casing and cross bar by described rubber coating.
Wherein, described adjacent vehicle bridge is respectively arranged with fixed support one and fixed support two, and described fixed support one is connected described ball end respectively with fixed support two.
Described pipe link one and described pipe link two hinged.
The beneficial effect of this programme can be learnt according to describing of such scheme, and structure is simple, reasonable in design, and the stability of load sensing valve mechanism and reliability are significantly strengthened.Montant two ends are connected with pipe link two with cross bar respectively by rubber coating, are first convenient to the effective length adjusting each bar, improve commonality; Secondly effectively can alleviate the physical shock of rod movable, avoid vehicle bottom to cause hinge to occur catching phenomenon because of silt pollution.Pipe link one, pipe link two are connected with vehicle bridge respectively by ball end, can eliminate vehicle and travel the twisting of the vehicle bridge when bad road conditions to the impact of sense mounted mechanism leverage.
