Accompanying drawing explanation
Fig. 1 is theory structure schematic diagram of the present invention;
Embodiment
Below in conjunction with accompanying drawing, the present invention is specifically described:
See Fig. 1, a kind of vehicle travels the stable device of buffering, comprise two oil cylinders 1 for lifting, accumulator 2, multi-way valve 3, operating valve 4, and to be between above-mentioned four parts and to be communicated with the stable system 5 of four parts, stable system comprises equilibrium valve 6, selector valve 7, one-way throttle valve 8, reduction valve 9, Flow valve 10, one-way valve 16, multi-way valve is communicated with rodless cavity 12 with the rod chamber 11 of oil cylinder respectively by two pipelines, equilibrium valve is arranged on two pipelines between multi-way valve and oil cylinder, equilibrium valve and selector valve, reduction valve also connects, Flow valve is communicated in equilibrium valve, between reduction valve selector valve, selector valve, reduction valve is also communicated with accumulator, described one-way throttle valve is connected between selector valve and reduction valve, one-way valve is serially connected with the output terminal of reduction valve.Wherein, Flow valve mainly controls to flow into the hydraulic pressure oil mass in accumulator, and reduction valve is to reduce the hydraulic fluid pressure entered in accumulator, makes to enter hydraulic fluid pressure in accumulator and accumulator adapts, and plays a protective role to accumulator.
A wherein mode of execution, stable system also comprises the relief valve 13 be connected between accumulator and reduction valve, and this relief valve is communicated with an oil sump tank 14.Another kind of mode of execution is: stable system also comprises the manual throttle valve 15 be connected between accumulator and reduction valve, and this manual throttle valve is communicated with an oil sump tank.Also has another mode of execution: be exactly connect a manual throttle valve 16 at the two ends of relief valve; In concrete enforcement, operating valve is tee ball valve, and selector valve is 2/2-way selector valve, and certainly, operating valve and selector valve can also carry out equivalent replacement, and if operating valve is four way ball valve, selector valve is the similar replacement of three position three-way change valve etc.
Principle of the present invention is: the rodless cavity of oil cylinder is connected with the accumulator being full of certain pressure, rod chamber is connected with fuel tank by multi-way valve, by set up between rodless cavity and accumulator there is damping function stable system in order to slow down compression shock, vehicle stabilization is travelled.
The innovative point of patent of the present invention is: 1, by Flow valve to accumulator topping up, flow can not be fought for during operating cyloinder action; 2, accumulator absorbs different with the response traffic of supplementing oil cylinder rodless cavity by one-way throttle valve, slow down compression shock further.Thus achieve vehicle stabilization traveling, improve the travelling comfort of driving, working efficiency, reduction oil consumption and improve the working life of structural member.
As shown in Figure 1, the present invention is illustrated further: multi-way valve is communicated with fuel tank, during operation multi-way valve 3, pressure oil is by the A mouth of stable system 5, through equilibrium valve 6, D mouth to stable system, oil cylinder 1 holds up by the large chamber entering oil cylinder, namely disabled vehicle can be lifted.Simultaneously, fluid flows through the Flow valve 10 of 11L/min, the reduction valve 9 of 15L/min@100bar, the one-way valve 16 of maximum current capacity 20L/min, the X1 mouth of stable system to accumulator 2 topping up of 1.6L, when accumulator 2 supercharging pressure reaches 100bar, one-way valve 16 is closed, topping up is complete, its topping up time is very short, almost with oil cylinder 1 stroke to synchronous during limit position, even if the effective generation effect of voltage-stabilizing system can be ensured like this.
When the vehicle is running, open P mouth when tee ball valve 4 is switched to the position on the left side and be communicated with A1 mouth, pilot pressure enters the K mouth of stable system from the A mouth of tee ball valve 4, makes 2/2-way selector valve 7 be switched to the position on the left side.Then the fluid of the rodless cavity of oil cylinder 1 is connected with accumulator 2 with the X1 of 2/2-way selector valve 7, one-way throttle valve 8, stable system through the C mouth of stable system.The rod chamber of oil cylinder 1 to be connected with multi-way valve 4 fuel tank through D mouth and the B mouth of stable system.When vehicle runs into the road surface of uneven or reaches certain speed, vehicle can produce and jolt, and oil cylinder 1 meeting is due to inertia generation moving direction up or down:
When oil cylinder 1 moves upward, its rodless cavity volume increases and forms certain negative pressure, now accumulator 2 is by the C mouth of the one-way valve of the X1 of stable system, one-way throttle valve 8,2/2-way selector valve 7, stable system, the increase of rapid repairing response oil cylinder 1 rodless cavity volume.Oil cylinder 1 rod chamber smaller volume, fluid of its compression to be connected with multi-way valve 4 through D mouth and the B mouth of stable system and to push back fuel tank.
When oil cylinder 1 moves downward, its rodless cavity volume reduces, fluid is pressure increase by compression, the fluid now compressed by the C mouth of stable system, 2/2-way selector valve 7, the throttle valve of one-way throttle valve 8, the X1 mouth of stable system and accumulator 2, Absorbing hydraulic pulsation.The negative pressure that the rod chamber of oil cylinder 1 is formed carries out repairing by fuel tank by the B mouth of multi-way valve 3, stable system and D mouth.
When pressure reaches 300bar, relief valve 13 is opened, and fluid flows back to oil sump tank by the T mouth of stable system, avoids exceeding the use pressure of accumulator 2 simultaneously, plays the effect of the whole device of protection and accumulator.
Opened by manual throttle valve 15 when needs change maintenance accumulator 2 and stable system, the pressure of accumulator 2, by the T mouth off-load of throttle valve 15, stable system, is convenient to maintenance.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
