Description
The cross reference of related application
The application requires in the U.S. Provisional Application No.60/589 of application on July 20th, 2004,282 rights and interests, and above-mentioned application quotes in full at this as a reference.
Technical field
According to a preferred embodiment of the present invention, provide a kind of method and apparatus that is used for easily transmission filter being connected on the pump.
Background technique
The common conduct of transmission filter and pump is component processing independently, is assembled together then as the part of vehicle transmission gear.General this assembling need be used fastening piece, and will spend manpower and inefficacy easily.More particularly, adopt fastening piece that filter is assemblied on the pump and can increase the fringe cost relevant with fastening piece, need fastening piece be engaged fully, and if fastening piece do not engage fully and/or premature failure, can cause so can not suitably connecting between filter and the pump.At last, do not engage fully and/or the fastening piece of premature failure will become flexible and produce noise beastly when vehicle operating.
Summary of the invention
One object of the present invention is to provide a kind of being used for that transmission filter is connected to improved method and apparatus on the pump.
Filter assemblies comprises a kind of locking linkage structure of reversing according to the preferred embodiment of the invention.More particularly, filter is inserted into and rotates about 90 degree in the pump then so that reverse the locking mechanism joint.Adopt this mode, can not need unnecessary fastening piece, spring clip, clamping plate etc. just can make filter remain on coupled condition, thereby reduce cost of material.Eliminating of these parts proves that from the negative those can not fallen into transmission device because of carelessness with the build-up member that forms such as fastening piece, spring clip, clamping plate occur, thereby causes the other parts inefficacy and/or increase noise beastly.
In a preferred embodiment, filter comprises the filter mouth of pipe, and this mouth of pipe comprises injected-formative plastic and extends from the filter housings one of plastics.Adopt this mode, can make a plurality of parts by single mould-forming simultaneously, thereby saved the cost relevant with assembling with manufacturing.
Describe enforcement best mode of the present invention in detail below in conjunction with accompanying drawing, therefrom can understand said structure of the present invention and other structure and advantage.
Description of drawings
Fig. 1 is the schematic representation of the part of the hydraulic systems among the present invention;
Fig. 2 is the normal axomometric drawing of the filter assemblies among the present invention;
Fig. 3 is the normal axomometric drawing of the pump assembly among the present invention; And
Fig. 4 is the sectional drawing that filter assemblies shown in Fig. 2 is connected to the part of the assembly of pump shown in Fig. 3.
Embodiment
With reference to the accompanying drawings, identical mark is represented identical or corresponding parts in each accompanying drawing, shows the schematic representation of transmission device fuid distribution system 8 among Fig. 1, and this distribution system comprises storage tank or the container 10 that preferably holds hydraulic fluid.Transmission pump 12 is extracted hydraulic fluid by filter 14 out from container 10.Hydraulic fluid after pump 12 will pressurize is exported to transmission device 16.The pressure maximum of pump output terminal mouth is by pressure regulator valve 18 decisions, and this valve flows to filter 14 with unnecessary pump duty.According to a preferred embodiment of the present invention, above-mentioned hydraulic fluid at first satisfies the pressure demand of transmission device, then satisfies the pressure demand of torque-converters, provides a part lubricated and cooling then, and after this unnecessary fluid returns filter 14.
With reference to figure 2, filter assemblies 14 comprises housing 24, and this housing has the filter cell (not shown) that is fixed thereon.Cylindrical filter output port part 28 is substantially vertically stretched out from housing 24 substantially, and according to a preferred embodiment, output port part 28 ends at the filter mouth of pipe 30.At least a portion of housing 24, the filter output port part 28 and the mouth of pipe 30 be the integral injection molding part preferably.This embodiment's outstanding advantage shows that filter assemblies 14 combines a kind of annular mouth of pipe design and do not need other parts, as coniform insertion body, realizes mouth of pipe function.
Filter output port part 28 preferably includes a companion flange 32.This companion flange 32 extends radially outwardly and around its circumference from filter output port part 28.According to a preferred embodiment, companion flange 32 forms the relative recess 34 in position.Companion flange 32 and shoulder 70 (shown in Figure 3, and the back will be described in detail) form a kind of locking mechanism that reverses that is suitable for keeping the jointing state of filter 14 and pump 12 and need not unnecessary fastening piece together.
With reference to figure 3, pump 12 comprises housing 40, forms cylindrical substantially input hole 48 on the housing 40.Input hole 48 is suitable for admitting filter output port part 28 (shown in Figure 2).The diameter of input hole 48 dwindles at shoulder 70 places, and this shoulder 70 is suitable for holding companion flange 32, and keeps filter assemblies 14 (shown in Figure 2) and pump 12 to be in jointing state in view of the above.Can be clear that in Fig. 4 shoulder 70 comprises downstream part 72 and upstream portion 74, form groove 76 in the middle of two-part.Get back to Fig. 3 now, shoulder 70 also comprises the relative notch part in position 78.
For filter 14 is assembled on the pump 12, filter output port part 28 is inserted in the pump input hole 48, thereby makes companion flange 32 aim at the notch part 78 of shoulder 70.Then, thus filter 14 rotates about 90 degree with respect to pump 12 makes companion flange 32 remain in the pump groove 76.Therefore, the companion flange 32 of filter 14 cooperates formation to reverse locking mechanism with the shoulder 70 of pump 12, make filter 14 be assemblied in by this structure and need not any unnecessary fastening piece on the pump 12.Show the filter assemblies 14 that is assemblied on the pump 12 among Fig. 4, this moment, companion flange 32 was arranged in groove 76, and was locked at this position by the downstream part 72 of shoulder 70 and upstream portion 74.
In a preferred embodiment, the present invention can be used in the U.S. Provisional Application No.60/589 that the name of applying on July 20th, 2004 is called " improved transmission pump and filter ", the nozzle structure that discloses in 275, above-mentioned application is quoted in full at this as a reference.Its favourable part is, the manufacturing tolerances of companion flange 32 and pump groove 76 can keep 1.5+/-mouth of pipe passage 64 (being presented among Fig. 2 of the cited application) width of 0.5mm.As described in the cited application, verified in whole excursion this mouth of pipe channel width effectively reduced cavitation phenomenon, the advantage of the mouth of pipe is combined with the simple assembly properties of assembly among the present invention reaches a kind of performance of excellence thus.Prove that in addition the injection moulding embodiment that a surface of contact is provided has the back pressure (in cited application have a detailed description) of enough intensity to bear the mouth of pipe between companion flange 32 and shoulder 70.This embodiment's advantage applies is not needing to adopt sheet metal and corresponding fasteners, has therefore reduced and additional parts and assembly cost related.
Implement best mode of the present invention although described in detail, implement the present invention yet the personnel that are familiar with related-art technology of the present invention can expect various alternative design and mode of execution in the claims protection domain.
