Embodiment
Referring to accompanying drawing, in all figure, the identical or corresponding part of same symbolic representation has illustrated the schematic representation of power transmitting fluids distribution system 10 among Fig. 1.Fuid distribution system 10 comprises storage tank or the container 12 that is preferably equipped with hydraulic fluid.Main pump 14 extracts hydraulic fluid by filter 16A from container 12.Service pump 18 extracts hydraulic fluid by filter 16B from container 12.The control module (not shown) according to car speed for example, pressure require, cooling requires, the serviceability of vehicle component or the like is selected 14,18 work of which pump.Pump 14,18 is sent to transmission device 20 with pressurized hydraulic fluid.Shuttle valve 23 has converged the output 17 of two pumps 14,18 and has been sent to pressure regulator valve 22, and pressure regulator valve 22 returns to excessive pump stream the inlet of main pump 14.According to a preferred embodiment of the invention, hydraulic fluid at first will satisfy the requirement of transmission device pressure, satisfies the requirement of torque converter pressure then, supplies some lubricated and coolings then, and excess fluid is returned to the inlet of main pump 14 then.
Referring to Fig. 2, main pump 14 is served as reasons from the coaxial-type pump of the output driving of motor (not shown).Those skilled in the art will be understood that, because the center line 24 of pump 14 is coaxial with the input shaft of transmission device (not shown), so it is " coaxial-type ".Pump 14 comprises being configured to and defines the pump housing 26 that is essentially columnar inlet opening 28.Service pump 18 is from the shaft type pump, and it preferably is subjected to electricity and drives, yet pump 18 is alternately driven by any present known devices of this purposes that is applicable to.Service pump 18 comprises installation surface 30, and installation surface 30 defines the inlet eye 32 of the inlet opening 28 that is substantially perpendicular to main pump 14.
Referring to Fig. 3, filter assemblies 34 comprises the single housing 36 with filter 16A, 16B (being shown among Fig. 4) of being placed in one.Housing 36 comprises upper shell member 36A and the lower shell body member 36B that is connected thereon.According to preferred embodiment, housing structure 36A and 36B weld together by the sound wave method after filter 16A, 16B are installed on wherein, yet housing structure 36A, 36B alternately connect according to any usual manner.Those skilled in the art will be understood that the sonic welded method need have the flange 38 of about 10mm around whole peripheries of housing 36.
The design that is suitable for holding the filter assemblies 34 of two filter 16A, 16B (being shown among Fig. 4) in the single housing 36 with single welded flange 38 helps compact design of the present invention.The design of conventional type twin filter needs the twin filter housing, and each filter housings comprises a flange that is similar to flange 38.Should be appreciated that the filter housings that two of encapsulation respectively have a 10mm peripheral flange are effective not as the equal single filter housings with single 10mm peripheral flange.In other words, the peripheral flange in the design of bivalve body needs more space than equal mono-hull design.In addition, because conventional type twin filter case design needs additional space to come allowable deviation between two filter housings, so its compactedness is poorer.
Lower shell body member 363 comprises filter inlet part 60.As seeing the most clearly among Fig. 4, filter inlet part 60 preferably defines main-inlet passage 62 and auxiliary entrance passage 64.Main filter inlet passage 62 keeps fluid to be communicated with main filter 16A and storage tank 12 (being shown among Fig. 1).After-filter inlet channel 64 keeps fluid to be communicated with after-filter 16B and storage tank 12.
As shown in Figure 2, when filter assembly 34 was on its mounting point, primary outlet part 48 and pilot outlet part 50 be Vertical location above the remainder of filter assemblies 34 preferably.When pump 14,18 had only an operation, the air accumulation in the filter assemblies 34 had advantageously been limited in this location of primary outlet part 48 and pilot outlet part 50.
Filter assemblies is connected on the pump by filter outlet is vertically inserted in the pump intake in a conventional manner.Yet, to observe, single filter housings 34 of the present invention has forbidden that housing is connected on main pump and the service pump in a conventional manner.More accurate, do not accomplish that in fact the location that produces the single housing with a plurality of outlets that can vertically insert and make these outlets has required validity so that correctly engage with main pump and service pump.In other words, the center line between a plurality of outlets that can vertically insert and distance between center line can not remain in correct the joint in the required tolerance range of main pump and service pump and still all realize satisfactory sealing in two pump intakes simultaneously.Correspondingly, proposed to be used for filter assemblies is connected in novel method on main pump and the service pump, will be described in greater detail below.
Referring to Fig. 2, will be described the method that filter assemblies 34 is connected on main pump 14 and the service pump 18 being used for subsequently once more.For filter assemblies 34 being connected on main pump 14 and the service pump 18, the primary outlet part 48 of filter housings 36 is inserted in the inlet opening 28 of main pump 14.Subsequently, filter assemblies 34 is rotated till the mounting flange 56 of pilot outlet part 50 engages the installation surface 30 of service pumps 18 around the center line of primary outlet part 48.Mounting flange 56 is connected on the installation surface 30 of service pump 18 subsequently so that make face seal 58 be pressed in therebetween.According to a preferred embodiment, utilize the threaded fastener (not shown) that passes steel plug-in unit 57 (being shown among Fig. 3) placement that mounting flange 56 is connected on the installation surface 30.Face seal 58 is suitable for holding manufacture deviation so that make above-mentioned Placement to provide correct engaging with main pump 14 and service pump 18 for filter assemblies 34.
Referring to Fig. 4, show the sectional view of filter assemblies 34.According to a preferred embodiment, filter housings 36 comprises bending part 66 so that main portion 68 and the slave part 70 that is putting main filter 16A and after-filter 16B respectively is provided.Alternatively, main portion 68 and slave part 70 can for example utilize the plug-in unit or the shelf (not shown) that place therebetween to separate in a conventional manner.Main filter 16A places the main portion 68 of housing 36, and after-filter 16B places the slave part 70 of housing 36.
Although above to realizing that optimal mode of the present invention describes in detail, those skilled in the art will recognize that within the scope of the appended claims be used to put into practice various alternate design of the present invention and embodiment.
