Description
Technical field
The utility model relates to a kind of connecting rod mechanism, particularly relates to a kind of multiaxis line hydraulic trailer steering linkage.
Background technology
Hydraulic trailer all needs to transport the large-tonnage goods at present, all be to improve haulage capacity by longitudinal spliced or horizontally-spliced a plurality of relatively independent modules, thereby realize overlength, super wide, the transportation of superelevation and heavy lift, this class multiaxis independent trailer steering swivel system is the four-wheel steering pattern, in steering procedure, need all wheels to participate in simultaneously turning to, make the steering swivel system complexity like this, in the actual shipment process, often find the hydraulic trailer steering swivel system often make some wheel especially medial axis wheel actual rotational angle corner desirable with it differ greatly, cause turn to travel in appearance hold in the palm to slide and sail and cause wheel to cross quick-wearing even blow out, tire major accident such as come off.Hydraulic trailer adopts multiaxis line hydraulic trailer connecting rod mechanism multi-mode four-wheel steering technology, the layout of steering track rod, turns to the installation of oil cylinder to have a strong impact on the layout of steering swivel system, thereby influences the turning efficiency of car load.
The utility model content
The multiaxis line hydraulic trailer steering linkage that technical problem to be solved in the utility model provides a kind of modularization, is convenient to splice is realized hydraulic trailer four-wheel steering and multi-mode steering.
For solving the problems of the technologies described above, the utility model comprises draw bar, side bogie truck, central turnplate, hydraulic actuating cylinder, steering track rod, porous hydraulic suspension spindle arm, and described steering track rod length is 3 kinds, is respectively 680mm, 762mm, 1500mm.
Press such scheme, described porous hydraulic suspension spindle arm is the multidigit orifice plate.
A kind of preferred, described central turnplate is one, and described hydraulic actuating cylinder is a pair of, and all turn to wheel set to be linked to be one group.
Another kind of preferred, described central turnplate is two, and described hydraulic actuating cylinder is two pairs, and all turn to wheel set to be divided into two groups.Described central turnplate is divided into each one of front and back, and each central turnplate is turned to by two Driven by Hydraulic Cylinder, and the two groups of wheel sets in described front and back are connected with central turnplate by steering track rod respectively; Before and after described hydraulic actuating cylinder is divided into two groups, be connected to form interaction relation between oil cylinder by shutoff valve, four way ball valve, described shutoff valve is the shutoff valve group.
The utility model is owing to be decided to be 3 kinds with steering track rod length: 680mm, 762mm, 1500mm, spindle arm is designed to the multidigit orifice plate, make steering hardware become modular construction, therefore can be according to the difference of concrete load bearing requirements, splicing by basic axis hydraulic trailer, be combined into the modularization steering swivel system of multiple axis, steering track rod connecting bore position rearranges according to axis quantity, finally realizes hydraulic trailer four-wheel steering and multi-mode steering.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is the utility model (six axis) connecting rod mechanism arrangement plan.
Fig. 2 is the hydraulic schematic diagram of Fig. 1.
The specific embodiment
As shown in Figure 1, when tractor truck provides steering power, it is tractor truck pulling draw bar 1, draw bar 1 drives side bogie truck 2 and rotates, side bogie truck 2 drives central turnplate 6 by big pull bar 3 and rotates, central turnplate 6 promotes hydraulic ram (I) 7 and steering track rod (680mm) 5, steering track rod (762mm) 8, steering track rod (1500mm) 10 move, and the steering track rod motion promotes porous hydraulic suspension spindle arm 4,9,11 and rotates; The motion of hydraulic ram (I) 7 drives trailer rear portion hydraulic ram (II) 12 motions, hydraulic ram (II) drives central turnplate (II) 13 motions, central turnplate (II) motion promotes the steering track rod motion of trailer rear portion, and the steering track rod motion promotes porous hydraulic suspension spindle arm and rotates.Thereby realize hydraulic trailer four-wheel steering and multi-mode steering.
As shown in Figure 2, turning to when being power with the hydraulic power source, is to realize by hydraulic power source drive link mechanism leverage, i.e. the leverage fluid pressure linkage.Quick coupling 14 is arranged on four angles of vehicle frame, the convenient hydraulic power source that connects; Two group oil cylinders are that hydraulic ram (I) 7 is connected by the four way ball valve in the hydraulic efficiency pressure system 15, bidirectional relief valve 16, shutoff valve group 17 with hydraulic ram (II) 12, form the interaction relation between oil cylinder, thereby two groups of wheel sets turn to synchronously before and after guaranteeing.20 points when quick coupling 14, when 22 oil inlets that connect propulsion source respectively and oil outlet, four way ball valve 15 is adjusted to position a, shutoff valve 17,21 close, shutoff valve group 18,19,20 open, pressure oil enters quick coupling 20 points from pressure source, by shutoff valve 18, four way ball valve 15, shutoff valve 20 enters the left side oil cylinder of hydraulic ram (I) 7 and the right oil cylinder of hydraulic ram (II) 12 respectively, two oil cylinders promote central turnplate (I) 6 and central turnplate (II) 13 respectively with Eight characters angular turn, because the right oil cylinder of hydraulic ram this moment (I) 7 and the left side oil cylinder of hydraulic ram (II) 12 are interaction relations, so all turn to wheel set all to center on a turning center motion, trailer realizes that the Eight characters turns to pattern; When four way ball valve 15 is adjusted to position b, pressure oil enters from 20 of quick couplings, enter the left side oil cylinder of hydraulic ram (I) 7 and the left side oil cylinder of hydraulic ram (II) 12 respectively by shutoff valve 18, four way ball valve 15, shutoff valve 20, two oil cylinders promote central turnplate (I) 6 respectively and central turnplate (II) 13 rotates with equidirectional, because the right oil cylinder of hydraulic ram this moment (I) 7 and the right oil cylinder of hydraulic ram (II) 12 are interaction relations, so all wheel sets all with identical angular turn, realize the diagonal pattern of trailer; When steering swivel system owing to air or external force reason, two group oil cylinders synchronously time the before and after making need be to the adjustment that resets of front and back two group oil cylinders.The working power source makes central turnplate (II) 13 forward the position vertical with vehicle frame in the front end quick coupling pressurization of vehicle, closes shutoff valve 19, re-uses the propulsion source pressurization, makes central turnplate (I) 6 forward the position vertical with vehicle frame to.Bidirectional relief valve 16 plays the safety guard-safeguard effect.When tractor truck provided steering power, central turnplate 6 rotated under the promotion of draw bar 1 and side bogie truck 1, and central turnplate 6 promotes wheel steering by steering track rod 5,8,10.When wheel meets obstructions when in stays; hydraulic ram on the central turnplate 6 (I) 7 or the pressure of hydraulic ram (II) 12 can raise; when pressure surpasses the nominal pressure of bidirectional relief valve 16; pressure oil overflows to the low-pressure cavity of opposite side oil cylinder by bidirectional relief valve 16, thereby steering swivel system is played a protective role.
It should be noted last that, the above specific embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
