Specific embodiment
The optimal technical scheme that the invention will now be described in detail with reference to the accompanying drawings.
As shown in Figure 1, a kind of caravan carriage transverse inertia buffer system of the invention, including the frame being mounted on chassis
Frame structure 1 is provided with buffer system between one group of opposite side of lateral direction of car of the frame structure 1；
The buffer system includes 2, two hydraulic cylinders 3 of support beam, and caravan trunk is fixed in support beam 2, and two
A hydraulic cylinder 3 is separately positioned on the two sides of support beam 2, and two hydraulic cylinders 3 are fixed in frame structure 1, support beam 2
Both ends be respectively arranged with a hydraulic piston 4, the piston end of the hydraulic piston 4 is placed in the hydraulic cylinder 3 of corresponding side, liquid
Hydraulic oil is filled in cylinder pressure 3；
It is provided with cushion cylinder 5 and compensating cylinder 6 outside the hydraulic cylinder 3, cushion cylinder 5 and compensating cylinder 6 pass through respectively
Oil circuit is connected to hydraulic cylinder 3, and piston is provided in cushion cylinder 5 and compensating cylinder 6, the piston in the cushion cylinder 5
In compressive state, hydraulic oil is full of in the compensating cylinder 6.
Sliding rail 7 is provided in the frame structure 1, the support beam 2 is slided in sliding rail 7.
At least provided with two buffer systems in the frame structure 1.
More oil line pipes, more oil line pipes and hydraulic cylinder 3 are provided between the cushion cylinder 5 and hydraulic cylinder 3
Junction is located at close to 3 bottom position of hydraulic cylinder.
The driving mechanism for controlling respective internal piston playback is provided with outside the cushion cylinder 5 and compensating cylinder 6.
The course of work is as follows: when vehicle is in turn or other situations, when generating transverse inertia, compartment drives support beam 2
Thrust is generated toward vehicle side, support beam 2 pushes the hydraulic piston 4 of the side, and hydraulic piston 4 exerts a force extruding in hydraulic cylinder 3,
Hydraulic oil in hydraulic cylinder 3 is oily to cushion cylinder 5 and 6 output hydraulic pressure of compensating cylinder by oil circuit by 4 pressure of hydraulic piston；
And oil liquid is filled in compensating cylinder 6, the piston in compensating cylinder 6 has been in maximum compression ratio state,
It can not be pushed, therefore, hydraulic oil can enter cushion cylinder 5, since the piston in cushion cylinder 5 is in compressive state, so
Piston will be slow the hydraulic oil promotion for being washed into cushion cylinder 5；
And the vehicle other side, support beam 2 can generate pulling force to hydraulic piston 4, due to the work in the cushion cylinder 5 of the side
Plug has been in compressive state, therefore cannot be pulled again, and 6 inner piston of compensating cylinder of the side is in maximum compression ratio state,
It is full of oil liquid in compensating cylinder 6, under the pulling force of hydraulic piston 4, forms negative pressure in the hydraulic cylinder 3 of the side, compensation can only be extracted
For oil liquid in oil cylinder 6 to make up negative pressure, such compartment can generate displacement in a lateral direction, to cope with the cross of moment generation
To inertia；
After inertia displacement, the driving mechanism on vehicle will adjust cushion cylinder 5 and compensation at the first time in each compartment
Piston in oil cylinder 6, makes piston playback, i.e. piston in cushion cylinder 5 is in compressive state, is full of liquid in compensating cylinder 6
Pressure oil, the piston in compensating cylinder 6 are in maximum compression ratio state, to wait inertia displacement next time.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not limited to this hair the foregoing is merely a specific embodiment of the invention
Bright, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in the present invention
Protection scope within.
