Abstract
The invention belongs to the technical field of mechanical transmission and provides a multifunctional pressure oil tank adjusting device to accurately judge whether the oil amount in the whole transmission device is in a normal work range or not. By arranging a constant pressure balance valve, an air pressure valve and a gulp valve, a pressure oil tank normally works when the transmission device works, and after the transmission device stops, the oil-level height in the pressure oil tank and the oil-level height of an oil sump are quickly balanced and consistent, so that whether the oil amount in the whole transmission device is in the normal work range or not can be accurately judged through the oil-level height measured by a dip stick of the oil sump; the air pressure valve is small in size and the mounting position is flexible; oil pumped back to the pressure oil tank by an oil scavenger pump contains much air, and the gulp valve can supplement air to the pressure oil tank, so the normal work of the pressure oil tank is ensured, an air pump in the conventional scheme is eliminated and the design of the transmission device is more facilitated.

After transmission device work is shut down; pressure oil tank 3 inner fluids cannot flow to oil sump 1; make each fluid amount and fuel head of oil sump 1 afterwards of shutting down there is uncertainty; the fuel head that cannot measure by oil sump 1 oil dipstick accurately judge that fluid amount in whole transmission device whether in normal range of operation, is unfavorable for work and the maintenance of transmission device.In addition, in existing Tank and Armoured Vehicle hydraulic machine comprehensive actuator, the pressure that adopts a guiding valve simultaneously to realize oil, material that two kinds of viscosity differences of gas are very large regulates, and pressure surge scope is large.
Summary of the invention
(1) technical problem that will solve
The object of the present invention is to provide a kind of multi-functional pressure fuel tank controlling device; when working, transmission device guarantees that pressure oil tank normally works; fluid after transmission device is shut down in pressure oil tank can flow to fast oil sump fuel head in pressure oil tank is consistent with oil sump fuel head, and the fuel head that so just can measure by oil sump oil dipstick is accurate judges that fluid amount in whole transmission device is whether in normal range of operation.
(2) technological scheme
For solving the problems of the technologies described above, the invention provides a kind of multi-functional pressure fuel tank controlling device, comprise oil sump, dump pump, pressure oil tank and oil supply system, described dump pump is withdrawn into the fluid of transmission device oil sump in pressure oil tank, pressure oil tank is each component working fuel feeding by oil supply system, it is characterized in that: this device also comprises level pressure equilibrium valve, air pressure valve, aeration valve and transmission device manipulation oil circuit, and the working state of described pressure oil tank is regulated by level pressure equilibrium valve, air pressure valve and aeration valve acting in conjunction.
Wherein, described level pressure equilibrium valve is arranged on the bottom position of pressure oil tank, and the working state of level pressure equilibrium valve is controlled by transmission device manipulation oil circuit.
Wherein, the entrance of described air pressure valve is arranged on the close tip position of pressure oil tank, and to determine the oil-gas ratin in pressure oil tank, the pressure in pressure oil tank has been determined in air pressure valve and the acting in conjunction of level pressure equilibrium valve.
Wherein, described aeration valve in oil sump flow process, can unidirectionally enter in pressure oil tank air at pressure oil tank inner fluid, and it is consistent that the fuel head of assurance pressure oil tank and oil sump reaches balance fast.
Wherein, when transmission device is worked, described transmission device handle structure has larger pressure, makes level pressure equilibrium valve in level pressure state, determines pressure oil tank internal pressure; When transmission device is shut down, transmission device is handled oil circuit does not have pressure, and level pressure equilibrium valve, in state of equilibrium, is communicated with pressure oil tank and oil sump.
(3) beneficial effect
Compared with prior art, the present invention possesses following beneficial effect:
1, multi-functional pressure fuel tank controlling device provided by the invention, by level pressure equilibrium valve, air pressure valve and aeration valve are set, when when guaranteeing transmission device work, pressure oil tank is normally worked, having realized after transmission device is shut down in pressure oil tank fuel head and oil sump fuel head, to reach fast balance consistent, and the fuel head that can measure by oil sump oil dipstick is thus accurate judges that fluid amount in whole transmission device is whether in normal range of operation;
2, in multi-functional pressure fuel tank controlling device provided by the invention, in definite pressure oil tank, the air pressure valve volume of oil-gas ratin is little, mounting point odd jobs;
3, the fluid that in multi-functional pressure fuel tank controlling device provided by the invention, dump pump is drawn back pressure oil tank contains more air, aeration valve can supplement air in pressure oil tank simultaneously, therefore this programme has saved the air pump of former scheme when guaranteeing the normal work of pressure oil tank, is more conducive to the design of transmission device.
