Abstract
The utility model provides a hydraulic oil tank which effectively integrates an oil cooler and reduces the mounting size. The hydraulic oil tank comprises an oil tank, the oil cooler and a scavenge filter; the oil tank and the oil cooler are integrated together; the oil tank is provided with two scavenge through holes; the two scavenge through holes are respectively and directly communicated with an oil inlet and an oil outlet at the two ends of the oil cooler through a very short pipeline; a bypass spillover valve is arranged at the scavenge through hole communicated with the oil inlet of the oil cooler; and when the carrying capacity of the oil cooler is decreased, the oil liquid can directly reflow to the oil tank after the pressure thereof achieves the opening pressure of the bypass spillover valve. The hydraulic oil tank has the following advantages of integrating the oil tank and the oil cooler together, reducing the mounting space and reducing the pipeline connection of a system. The bypass spillover valve is arranged at the scavenge through hole; when the overflowing channel of the oil cooler is plugged or the liquid is extremely viscous due to too low temperature and the oil liquid pressure achieves the opening pressure of the bypass spillover valve, the oil liquid can directly reflow to the oil tank so as to avoid the elements of the hydraulic system from being damaged.
Description
Technical field
The utility model relates to a kind of hydraulic oil container with oil cooler, is mainly used in the less situation of fuel tank volume in the mechanically moving.
Background technique
For dilly such as two-wheeled motorcycle, four-wheel motor cycle vehicle-mounted hydraulic system, because existing arrangement space is limited, if the mode of installing with the hydraulic element independent separate of hydraulic system according to fixed equipment realizes, then need on the car body basis, set up the support that hydraulic element are installed, this certainly will increase the size of car load, influence mobility, safe driving is caused certain negative effect.
Summary of the invention
But technical problem to be solved in the utility model provides a kind of effective integration oil cooler, reduces the hydraulic oil container of installation volume.
In order to solve technique scheme, the utility model adopts following technological scheme:
A kind of hydraulic oil container with oil cooler, comprise fuel tank, oil cooler, return filter, it is characterized in that: described fuel tank and oil cooler integrate, described fuel tank is provided with two oil return through-holes, two oil return through-holes respectively with directly being connected by very short pipeline of oil cooler two ends into and out of hydraulic fluid port, the oil return through-hole place that is connected with the oil cooler filler opening is provided with a bypass relief valve, when the oil cooler conveyance capacity descended, oil liquid pressure can directly flow back to fuel tank after reaching this vent relief valve cracking pressure.
One section steel pipe is welded at described two oil return through-hole places respectively, steel pipe one end is in the fuel tank, the other end is in outside the fuel tank, be in the outer end of fuel tank nut all is housed, the oil inlet and outlet at oil cooler two ends is welded with one section respectively and is with externally threaded steel pipe, fuel tank and oil cooler be connected by nut be with the realization that is threaded of externally threaded steel pipe.
Described vent relief valve is installed in oil cooler filler opening one side and the steel pipe that fuel tank is connected.
The end of steel pipe in fuel tank that described oil cooler oil outlet one side is connected with fuel tank is connected with return filter.
The utility model compared with prior art has the following advantages: that volume in the hydraulic system is bigger two auxiliary devices---fuel tank and cooler integrate, and have reduced installing space, have reduced the connection of system pipeline.Be provided with a bypass relief valve at the oil return through-hole place, its role is to stop up or fluid Yin Wendu when crossing low special thickness and causing conveyance capacity to descend when the oil cooler flow channels, oil liquid pressure can directly flow back to fuel tank after reaching this vent relief valve cracking pressure, in order to avoid the hydraulic system element is destroyed.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is to be to implement under the prerequisite with technical solutions of the utility model; provided detailed mode of execution and process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, 2, the utility model mainly comprises fuel tank 1, return filter 2, air-strainer 3, oil thermometer 4, air-cooled oil cooler 5, vent relief valve 6.Fuel tank 1 and oil cooler 5 integrate, fuel tank 1 bottom is provided with two oil return through-holes 7,8, two oil return through-holes 7,8 respectively with being connected of oil cooler 5 two ends into and out of hydraulic fluid port 9,10, oil return through-hole 7 places that are connected with oil cooler filler opening 9 are provided with vent relief valve 6, its role is to stop up or fluid Yin Wendu when crossing low special thickness and causing conveyance capacity to descend when oil cooler 5 flow channels, oil liquid pressure can directly flow back to fuel tank 1 after reaching these vent relief valve 6 cracking pressures, in order to avoid the hydraulic system element is destroyed.
In the present embodiment, one section steel pipe 11 is welded at two oil return through-hole 7,8 places respectively, steel pipe one end is in the fuel tank 1, the other end is in outside the fuel tank 1, be in the outer end of fuel tank nut 12 all is housed, being welded with one section respectively into and out of hydraulic fluid port 9,10 and being with externally threaded steel pipe 13 of oil cooler 5 two ends, fuel tank 1 and oil cooler 5 be connected by nut 12 be with the realization that is threaded of externally threaded steel pipe 13.Vent relief valve 6 can be installed in oil cooler filler opening 9 one sides and the steel pipe 11 that fuel tank 1 is connected, and the end of the steel pipe 11 that oil cooler oil outlet 10 1 sides are connected with fuel tank 1 in fuel tank is connected with return filter 2.
Fluid enters through another filler opening 14 of oil cooler 5, this moment is not if oil liquid pressure reaches vent relief valve 6 cracking pressures, vent relief valve 6 is not opened, fluid is after oil cooler 5 coolings, enter return filter 2 in the fuel tank from oil cooler oil outlet 10, after 2 filtrations of oil return filter, flow back in the fuel tank 1, when oil cooler 5 flow channels are stopped up, after oil liquid pressure reaches vent relief valve 6 cracking pressures, vent relief valve 6 is opened, and fluid directly flows back to fuel tank 1 from vent relief valve 6, no longer through oil cooler 5 coolings.
