Abstract
The invention relates to an oil pump which is arranged in a crankcase oil tray to provide cooling and lubricating for an engine with adjustable depth of oil gathering depth. A hydraulic fluid port of the oil pump is connected with a sleeve shaped oil gathering port support, is provided with a filter screen, and is in detachable connection with the oil gathering port support. When the engine is arranged according to a required mode, the crankcase oil tray is modified correspondingly, so that adaption can be realized conveniently only by properly changing an oil pump with proper length and specification, and the requirement of transversely and vertically arranging the engine can be fulfilled without redesigning the whole oil pump.
Description
Technical field
The oil pump that the present invention relates to use on the automobile specifically is exactly that device provides cooling and lubricated oil pump to motor etc. in oil sump.
Background technique
Oil pump is most important parts in the lubricating system, and its function is the machine oil that enough pressure and flow are provided for lubricating system, and oil pressure must guarantee in certain scope, obtains lubricating fully and not damaging relevant pressure part to guarantee each friction member.Oil pump has conclusive effect in the exploitation of whole engine lubrication system, the blood circulation system that can liken into whole lubricating system human body, oil pump is exactly the heart of lubrication system, each oil duct branch road is exactly a blood vessel, oil pump provides the circulation of blood continuously for each component in the operation process of motor, guarantee motor normally operation under each operating mode.
Objective demand along with development of technology and market, require the variation of engine arrangement now, as horizontal, vertical exploitation of putting motor, in order to satisfy the performance requirement of motor, oil sump need change, the oil pump that is contained in like this in the oil sump just needs exploitation again, so not only causes the prolongation of construction cycle, has also increased the expense of exploitation on the other hand.
On the other hand, in order to satisfy the requirement of Hyundai Motor to the high efficiency of motor, low oil consumption and low emission, a lot of motors have all adopted as new technologies such as variable valve control system, HLA valve mechanisms, and these The Application of Technology all need the stable engine oil pressure of motor.The oil pump pressure-limit valve of motor is when draining at present, and machine oil sprays at a high speed from the spill port on the pressure-limit valve, has produced a large amount of bubbles after the gas collisions of these machine oil and crankcase, the friction.The vibration of motor in addition also can produce bubble to machine oil, because bubble has compressibility, therefore can influence the fluctuation of main oil gallery engine oil pressure.
Summary of the invention
Primary and foremost purpose of the present invention just provides a kind of oil pump of oil-collecting depth-adjustment, oil pump and sump strainer are become one and is suitable for the oil pump of the oil sump of all size.
For achieving the above object, the present invention has adopted following technological scheme: a kind of oil pump of oil-collecting depth-adjustment, it is characterized in that: the oil port of oil pump is connected with canular oil collecting mouth support, and oil port is provided with filter screen, and hydraulic fluid port is that disassembly-type is connected with oil collecting mouth support.
In the such scheme, oil pump and sump strainer is integrated, reduced the quantity of part on the one hand, also make the modularization of motor, when motor when mode is arranged on request, oil sump also will be made corresponding modify, like this as long as suitably the oil pump of suitable length and specification is selected in change for use, just can realize adaptively easily, and need not whole oil pump is redesigned; Because the machine oil mouth, only needs change oil collecting mouth support by being connected by disassembly-type with the oil trap support, just can reach and satisfy the horizontal and vertical layout requirement of putting of motor.
Description of drawings
Fig. 1 is a plan view of the present invention;
Fig. 2 is a worm's eye view;
Fig. 3,4 is respectively A-A, the B-B sectional view among Fig. 1;
Fig. 5 is the A-A sectional view among Fig. 2.
Embodiment
In conjunction with the accompanying drawings, hydraulic fluid port 11 places of oil pump 10 are connected with canular oil collecting mouth support 20, and hydraulic fluid port 11 places are provided with filter screen 30, and hydraulic fluid port 11 is connected for disassembly-type with oil collecting mouth support 20.Machine oil enters hydraulic fluid port 11 through oil collecting mouth support 20 by filter screen 30, pumps high pressure oil and be transported to motor enforcement cooling with lubricated under the rotor effect.Main points of the present invention are hydraulic fluid port 11 and oil collecting mouth support 20 can to satisfy the occasion of various oil sumps and to use when changing the oil collecting mouth support 20 of different size for disassembly-type is connected.
What illustrate among Fig. 3 is the installation situation of snap ring 40, illustrates then among Fig. 4,5 that the oil collecting mouth support 20 of two kinds of specifications is installed example.
Specify below in conjunction with accompanying drawing.
Shown in Fig. 4,5, the upper end-hole place of described oil collecting mouth support 20 is provided with outside flange 21, and hydraulic fluid port 11 places are provided with annular steps shape groove 12, and the flange 21 on the oil collecting mouth support 20 is positioned at described annular steps shape groove 12 places together with the edge of filter screen 30.
The bottom of the flange 21 on the described oil collecting mouth support 20 is provided with snap ring 40, and the flange 21 on the edge of the filter screen 30 of Bu Zhiing and the oil collecting mouth support 20 compresses fixing by snap ring 40 from top to bottom.Described snap ring 40 is the ring of elastic opening shape, referring to Fig. 2, need only during assembling with instrument and clamp snap ring 40 and the suitable folding size that keeps its opening, it is delivered to annular steps shape groove 12 places and place the groove of the below of the flange 21 position next-door neighbour persons on the oil collecting mouth support 20, snap ring 40 suitably struts with himself elastic force, this moment is just spacing securely firmly with the edge and the flange 21 on the oil collecting mouth support 20 of filter screen 30, realized that filter screen 30 and oil collecting mouth support 20 are fixing, this structure is easy for installation, connection is reliable.The lower end mouth limit 22 of oil collecting mouth support 20 is inside wiredrawn edge shape, see Fig. 5, adopt this structure, because the lower end mouth limit 22 of oil collecting mouth support 20 is comparatively slick and sly, guaranteed the smoothness of oil suction effect on the one hand, on the other hand, guarantee in assembly process that oil collecting mouth support 20 lower end mouth can not scratch hand.The machine oil pumping hole integrates by the oil trap of snap ring and simplification, can satisfy the horizontal vertical needs of putting engine development of company easily by changing oil collecting mouth support.
Described hydraulic fluid port 11 inboards are provided with pressure-limit valve 50, pressure-limit valve 50 is provided with the aperture 51,52 that is communicated with pressure chamber 112 and oil suction chamber 111 respectively, and the spool 53 in the pressure-limit valve 50 can be in respectively under the elastic force effect above-mentioned aperture 51,52 is communicated with or the rest position place.
Above-mentioned pressure-limit valve is arranged on the neutral position of the filler opening and the oil outlet of oil pump, and when the oil pump outlet pressure surpassed certain scope, the high-pressure oil in the pressure chamber 112 leaked in the oil suction chamber 111 by pressure-limit valve 50.Because oil pump under the oil sump liquid level, has avoided machine oil to spray at a high speed from the spill port on the pressure-limit valve, with gas collisions, a large amount of bubble of friction back generation of crankcase.
