Technical field
The present invention relates to a kind of way to play for time, especially a kind of caravan carriage transverse inertia way to play for time belongs to vehicle inertial
Property control system field.
Background technique
Caravan, also known as " family on wheel " have both " room " and " vehicle " two big function, but its attribute or vehicle, are that one kind can
The car type of basic facilities mobile, with herbal, present more and more people are ready to select oneself to open caravan with one
Household goes out to travel, and observes and learn from real life, and therefore, the handling and riding comfort of caravan is just increasingly becoming people choose caravan one
The rest environment in major criterion, especially compartment, when trudging, road conditions be frequently not it is ideal, encounter urgency
It is curved or jolt road when, the passenger for resting or lying fallow in compartment just will receive influence, and ride experience is bad.
Such as a kind of compartment limit damper of Patent No. 201410599377.3, including arc spring steel plate, installation
Plate, limited block, yielding rubber pad, contact base plate, square tube and square tube sealing plate.The arc spring steel plate is assembled to mounting plate
On；Mounting plate is welded in contact base plate and square tube；Limited block is welded in mounting plate two sides respectively；Yielding rubber pad is mounted on contact
On bottom plate；Contact base plate is welded on square tube upper end；Square tube seal plate welding is in square tube lower end.It can be realized using the present invention in self-unloading
Vehicle or compartment be removably in hydraulic system, the limit that compartment front falls with limit, left and right before and after compartment when frame contact
And buffering when compartment whereabouts, structure is simple, and easy to use, reliable, limiting buffer effect is good, and this buffer unit uses solid
The buffer unit of structure is determined, therefore the proportion of goods damageds are relatively high, for a long time using just needing replacing.
The for another example outer compartment buffer structure on a kind of school bus of Patent No. 201420132453.5 belongs to automotive engineering neck
Domain.It solves existing school bus the technical problems such as cannot buffer well when by external impact.A kind of outer vehicle on school bus
Compartment buffer structure, school bus includes an outer compartment and an interior compartment, with gap between outer compartment and interior compartment, before outer compartment
End is provided with an energy-absorption box, is connected between energy-absorption box and outer compartment by several guide posts, and energy-absorption box can be opposite with guide post outer
Carriage movements are fixedly installed a support plate on outer compartment, this buffer structure includes several hydraulic cylinders three, the cylinder of hydraulic cylinder three
Reset spring three is provided between body and support plate, hydraulic cylinder three has liquid storage chamber three, offers on the cylinder body of hydraulic cylinder three excessive
Discharge orifice two is connected with the hydraulic tube for communicating liquid storage chamber three with liquid reserve tank at overflow hole two.The utility model have school bus by
The advantages that can be good at buffering when to external impact changes compartment buffer structure just for the buffering of vehicle heading, solves
Buffering under emergency case, and cannot inertia to vehicular transverse direction and impact force buffer.

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 way to play for time of the invention is based on a kind of inertia buffer system, it should
System includes the frame structure 1 being mounted on chassis, is provided between one group of opposite side of lateral direction of car of the frame structure 1 slow
Flushing system；
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.
Based on a kind of way to play for time of caravan carriage transverse inertia buffer system, the course of work is as follows: when vehicle is turning round
Or other situations, when generating transverse inertia, compartment drives support beam 2 to generate thrust toward vehicle side, and support beam 2 pushes should
The hydraulic piston 4 of side, hydraulic piston 4 exert a force extruding in hydraulic cylinder 3, and the hydraulic oil in hydraulic cylinder 3 is pressed by hydraulic piston 4
Power by oil circuit to cushion cylinder 5 and compensating cylinder 6 output hydraulic pressure oil, and fills with oil liquid, compensation oil in compensating cylinder 6
Piston in cylinder 6 has been in maximum compression ratio state, can not be pushed, and therefore, hydraulic oil can enter cushion cylinder 5, by
It is in compressive state in the piston in cushion cylinder 5, 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, since the piston in the cushion cylinder 5 of the side has been in pressure
Contracting state, therefore cannot be pulled again, and 6 inner piston of compensating cylinder of the side is in maximum compression ratio state, in compensating cylinder 6
Full of oil liquid, under the pulling force of hydraulic piston 4, negative pressure is formed in the hydraulic cylinder 3 of the side, can only extract the oil in compensating cylinder 6
For liquid to make up negative pressure, such compartment can generate displacement in a lateral direction, to cope with the transverse inertia of moment generation, every time
After inertia displacement, the driving mechanism on vehicle will adjust the work in cushion cylinder 5 and compensating cylinder 6 at the first time in compartment
Plug, makes piston playback, i.e. piston in cushion cylinder 5 is in compressive state, is full of hydraulic oil, compensation oil in compensating cylinder 6
Piston in cylinder 6 is 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.
