Description
2360078 1 APPARATUS FOR TESTING SOLENOID VALVES FOR AUTOMATIC VEHICLE
TRANSMISSION SYSTEMS This invention relates to apparatus for testing solenoid valves for automatic vehicle transmission systems.
Automatic vehicle transmission systems utilise solenoid valves for controlling required gear changes. Solenoid valves direct hydraulic fluid to appropriate hydraulic devices in order to change gear ratios.
There are many different manufacturers of automatic vehicle transmission systems, and each manufacturer manufactures a number of different types of such automatic transmission systems. The automatic vehicle transmission systems are controlled by microprocessor based electronic apparatus. As technology develops, so does the methodology for both solenoid control and microprocessor electronic control strategy. A number of different types of solenoid valves are currently employed and these include simple on/off solenoid valves, pulse width modulated solenoid valves, and proportional solenoid valves.
The solenoid valves are integrated into main structural components of the automatic vehicle transmission systems. In many cases, a complete strip down of the transmission systems is required in order to gain access to the solenoid valves. It is therefore important that, when a transmission system is being assembled or reconditioned, the solenoid valves that are being installed are known to 2 function correctly. The solenoid valves are expensive, as is the time required for strip down and re-assembly. There is thus a considerable requirement to have confidence that the solenoid valves will operate correctly and will not prematurely fail, thereby giving rise to warranty claims and associated unwanted expense.
It is an aim of the present invention to provide the above requirement.
Accordingly, in one non-limiting embodiment of the present invention there is provided apparatus for testing solenoid valves for automatic vehicle transmission systems, which apparatus comprises a mounting block for receiving the solenoid valves, electronic control means for electrically operating the solenoid valves in the mounting block, pressure control means for controlling the pressure of a fluid applied to the solenoid valves in the mounting block, and display means for indicating if the solenoid valves in the mounting block are operating correctly, and the mounting block being such that it is constructed and adapted to receive substantially all available different types of solenoid valves.
The mounting block is able to receive substantially all available different types of solenoid valves by either receiving the solenoid valves directly or via adaptors and plug-in flexible pipes. The mounting block is preferably to be capable of performance expansion by in order to allow future designed receiving additional adaptors, 3 designs of solenoid valves also to be tested. By having such a flexible mounting block, there is. achieved a considerable reduction both in the time to set up solenoid valves for test, and in the tooling that was previously necessary for testing each of the many differing types of solenoid valves that are available.
Usually, the apparatus of the present invention will be able to test at least two of the solenoid valves at any time.
Preferably, the mounting block has a plurality of apertures for receiving the solenoid valves, or for receiving adaptors for receiving the solenoid valves, the apertures being connected to internal passageways in the mounting block. Apertures that are not required can be plugged or otherwise kept out of use. Apertures can be arranged as appropriate to take simple fittings to direct fluid to a solenoid valve or solenoid valves being tested in the mounting block.
Preferably, the apparatus is one in which the electronic control means, the pressure control means and the display means are all on a control panel.
Preferably the fluid is air. Any suitable and appropriate fluid may however be employed including hydraulic transmission fluid such as oi The display means preferably comprises a plurality of pressure gauges. The display means may alternatively or additionally comprises a light emitting diode display.
4 An embodiment of the invention will now be described solely by way of example with reference to the accompanying drawings in which:
Figure 1 is a perspective view of apparatus for testing solenoid valves for automatic vehicle transmission systems; Figure 2 is a front view from above of the apparatus shown in Figure 1; Figure 3 is a side view of the apparatus shown in Figure 1; Figure 4 is a perspective view of a mounting block employed in the apparatus 'shown in Figure 1; and Figures 5, 6 and 7 show the mounting block of Figure 4 but receiving different types of solenoid valves to the solenoid valve shown in Figure 4.
Referring to Figures 1 - 4, there is shown apparatus 2 for testing solenoid valves 4 for automatic vehicle transmission systems. The apparatus 2 comprises a mounting block 6 for receiving the solenoid valves 4, electronic control means 8 for electrically operating the solenoid valves 4 in the mounting block 6, and pressure control means 10 for controlling the pressure of a fluid applied to the solenoid valves 4 in the mounting block 6. The apparatus 2 further comprises display means 12 for indicating if the solenoid valves 4 in the mounting block 6 are operating correctly. The mounting block 6 is such that it is constructed and adapted to receive substantially all available different types of solenoid valves.
The mounting block is able to test two or more of the solenoid valves at the same time. The mounting block 6 has a plurality of apertures 14 as shown in Figure 3 for receiving the solenoid valves 4. The apertures 14 may alternatively receive adaptors for receiving the solenoid valves 4. The apertures 14 are connected to internal passageways 16 in the mounting block 6, also as shown in Figure 3. The internal passageway 16 are connected by pipes 18 to the pressure control means 10.
The electronic control means 8, the pressure control means 10 and the display means 12 are all on a control panel 20. The control panel 20 is formed as a front part of a housing 22. As shown in Figure 3, the housing 22 has a side 24 which is provided with various cut outs 26 for receiving services in and out.
The apparatus 2 may operate with air as the f luid, or with any other suitable and appropriate type of f luid. Figures 1 and 2 show how the apparatus 2 has a mains air supply shut-off valve 27 which is movable between open and closed positions. when the shut-off valve 27 is open and admitting air, then the air pressure is controlled by rotating a control knob 29 which forms part of the pressure control means 10.
As can best be seen f rom Figures 1 and 2, the display means 12 comprises five pressure gauges 28. The display 6 means 12 may also comprises light emitting diode displays 30.
The solenoid valve 4 shown in Figure 4 is a simple on/off solenoid valve 4. The various available other apertures 14 for receiving other solenoid valves have been blanked off by plugs 32, 34 as shown. The plugs 34 may be supported in a holder 36 which is able to serve as a plug holder 36 and/or a valve holder 36. Figure 4 also shows a more complex plug 38 blocking one of the apertures 14 in the mounting block 6.
Figure 5 is a view like Figure 4 except that the solenoid valve 4 shown inFigure 4 has been removed and its aperture 14 plugged with one of the plugs 32. Others of the plugs 32 have been removed as shown to receive downwardly projecting pipe portions 40 which project downwardly from an adaptor 42. The adaptor 42 enables a solenoid valve pack 44 to be tested.
Figure 6 is a view like Figure 4 except that the solenoid valve 4 has been replaced by a plug 32. Also, the plug 38 has been removed and replaced by a solenoid valve 46. The solenoid valves 4 are simple on/off solenoid valves, whereas the solenoid valve 46 is a variable output solenoid valve.
Figure 7 is a view like Figure 4 but shows a solenoid valve 48 under test instead of the solenoid valve 4. Also, the plugs 34 have been removed and provided with devices 50 7 as shown. Leads 52, 54 and further devices 56, 58 are employed as shown.
Figures 1, 2 and 3 show how the apparatus 2 is provided with a bridge 60. The bridge 60 comprises a pair of side plates 62, 64 which support a pair of bars 66. A clamp 70 is slidably supported on the bars 66. The clamp 70 has a vertical holding shaft 72 which is able to press on an appropriate one of the solenoid valves 4 and hold it in position during testing. This is in order to hold the solenoid valve 4 under test in position to stop it being forced out by air pressure in the apparatus 2.
The apparatus 2 similiarly has a clamp arrangement 74 comprising a handle 76 and a frame 78. The handle 76 operates a horizontal holding shaft 80 which is able to hold in place solenoid valves being tested in the position shown by the plugs 34 in Figures 1 and 2.
As can also be seen from Figures 1 and 2, the apparatus 2 includes a test button 82 for turning on and off electronic equipment for the solenoid valves 4. The apparatus 2 also includes a pulse width modulated solenoid control knob 84.
It is to be appreciated that the embodiment of the invention described above with reference to the accompanying drawings has been given by way of example only and that modifications may be effected. Thus, for example, the shape of the mounting block 6 may be different from that shown in the drawings.
