Description

DETAILED DESCRIPTION OF THE INVENTION

(Background) 1. FIELD OF THE INVENTION The present invention relates to an apparatus for exchanging fluid in a transmission and, optionally, to an apparatus for flushing transmission components and replacing it with fresh fluid. 2. Description of the Prior Art Many consumer and industrial devices use automatic transmission fluid (ATF) as the working fluid.
) Is filled with an automatic transmission. This automatic transmission fluid must be removed from the transmission at regular intervals and replaced with fresh fluid. This is because the properties of the fluid degrade over time and use, resulting in contamination and debris that cannot be completely removed by the filters in the transmission.

[0002] Automatic transmissions require transmission fluid. This is because part of the fluid is used as drive means in the transmission, and in addition, is used to lubricate components in the transmission. Over time, this fluid becomes less viscous and the lubricating effect on the components decreases. Therefore, it is desirable to periodically exchange fluids to maintain the viscosity of the fluid in the transmission and to keep the transmission clean, thereby increasing the useful life of the transmission. Preferably, the entire volume of the fluid is exchanged so that the spent fluid and any undesired foreign substances contained therein are completely removed and replaced with a new fluid having a higher viscosity.

[0003] Considering a normal passenger car, this procedure usually involves removing the transmission pan from the transmission and draining fluid therefrom. Transmission pans typically contain from about 0.946 liters to about 4.73 liters (1-5 US quarts) of the total transmission capacity of about 6.6 liters to about 14.2 liters (7-15 US quarts). ). Thus, emptying the pan and adding new fluid will only serve to dilute the spent fluid with as little as 15-50% new fluid. After draining from the pan, the new transmission fluid to be refilled is supplied to the transmission to the appropriate fluid level using an oil level gauge. However, this procedure has significant drawbacks. In particular, the fluid present in the pan at a given time is only a fraction of the fluid actually present in the transmission. Typically, much of the transmission fluid is transmitted to the transmission control circuit, torque converter,
Stays in the transmission cooler. Thus, with conventional transmission fluid exchange, in practice, only about 1/4 to 1/3 of the transmission fluid is exchanged, and the transmission must be operated with a mixture of old and new fluids. The efficiency is reduced. More particularly, the present invention relates to a method and apparatus wherein cleaning mix is automatically introduced into the transmission, the entire transmission system is cleaned, and fluid is automatically flushed from the transmission upon refill. It is.

[0004] In the field of devices for flushing and filling fluids of motor vehicles or transmissions, various embodiments of such devices have become known in the past years. For example, specific examples of such species include U.S. Pat. Nos. 4,095,673 and 4,095,673.
Nos. 674,456, 5,056,612, 5,427,202, 5,
Nos. 447,184, 5,456,295, 5,318,080, 5,
No. 626,170. Prior art flushing and filling devices have several disadvantages associated with them. For example, in many prior art methods, flushing and filling an automatic transmission with a fluid, ie, oil, requires a relatively time-consuming and cumbersome and inefficient process. The conventional method is to exchange fluid in the transmission pan. It is difficult to remove all the fluid inside the system, and it is also difficult to clean the inside of the system. More recently, to replace all fluid in the vehicle's transmission, remove the fluid line and drain the fluid to the sump, while manually injecting new fluid into the transmission oil level gauge hole. Have also been tried. This procedure is inefficient,
It was inappropriate and time consuming, and did not spread widely.

Another known method is to disconnect the cooling line for the transmission fluid and allow the fluid to drain freely from one end of the line where spent fluid is present, while connecting the other end of the line to a pressurized tank. And injecting unused fluid from the tank into a cooling line connected to the transmission. One major drawback with this method is that in many cases, the flow exiting the transmission cannot be matched to the flow of unused fluid entering the transmission. The reason for this is that the transmission cannot accept the same amount of fluid as the used fluid flowed by the transmission pump into the unrestricted cooling line due to internal resistance. During this procedure, fluid seals, rear bearings, and other components inside the transmission are at risk of being damaged due to a gradual decrease in fluid levels in the transmission. Added to this difficulty is the fact that, for different transmission models, the flow resistance changes. Another proposal in this field is to provide transmission fluid via a transmission cooling line.
An example is a transmission exchanger that includes an air compression tank for discharging. Yet another proposal uses a supply pump device to supply the transmission fluid at a controlled flow rate to the transmission, or a flow control device to control the flow in the supply line, thereby reducing the unused fluid flow rate. The flow rate of used fluid discharged from the machine is not exceeded. In this way, the target flow level can be maintained in the transmission during the replacement procedure.

SUMMARY OF THE INVENTION In general terms, the present invention provides an apparatus for cleaning, removing, and replacing automatic transmission fluids. The apparatus includes a discharge line that is detachably and selectively connected to an additive reservoir and a variable discharge reservoir, and is normally disconnected to guide spent transmission fluid to a radiator of the vehicle. And a radiator port to which the cooling line is normally connected, which includes a filling tube removably connected to the cooling line. The outlet pipe is selectively connected to the additive reservoir, and the disconnected cooling line is connected to the additive reservoir so that the fluid in the transmission circulates as if it were connected. The additive reservoir is located in the flow line, injects the cleaning additive into the transmission system, and connects the other end of the cooling line and the flow line together to a cylindrical discharge and fill tank. The tank collects used fluid,
It has chambers separated by walls that pivot about a tank longitudinal axis for injecting new fluid into the transmission system. The transmission fluid pump is used to allow spent fluid to pass through a disconnected cooling line and into a discharge reservoir, while a feed pump simultaneously passes unused fluid through a supply tube. Into the radiator cooler port.

[0007] These and other objects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, taken in conjunction with the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments described herein are not intended to be exhaustive of the invention or to be limited to the precise forms disclosed. The embodiments describe the principles of the invention and its application and practical use, and have been chosen so that those skilled in the art can utilize the principles. In the following, reference will be made more particularly to the drawings wherein like parts are provided with the same reference numerals throughout the description.

FIG. 1 shows a simplified block diagram of the present system. A vehicle transmission 20 and a transmission fluid cooler (radiator) 22 are shown. The first fluid line 24 (discharge fluid line) is connected from the transmission outlet side to a device generally indicated by reference numeral 26 for cleaning and flushing the transmission fluid. When the first fluid line 24 is not connected to the transmission cleaning / flushing device 26, the radiator 22 is connected to the transmission 20 as shown by a broken line 24a. This is the normal circuit of the vehicle. Also, this is the transmission 20 and the radiator 2
2 is a normal connection. Therefore, when attempting to flush and transfer fluid from the transmission, the flow circuit between the radiator 22 and the transmission 20 is interrupted at the radiator 22 of the transmission, and the apparatus of the present invention is operated with the transmission and its radiator. Into the flow circuit.

Each transmission has a built-in pump 28 that has sufficient output to allow fluid in transmission 20 to flow from transmission to radiator 22 and back to transmission 20.
This allows the transmission fluid to cool during normal operation of the transmission. Fluid from radiator 22 flows into transmission 20 via line 30. One of the two pipelines 24a, 30 which is the normal circulation pipeline of the transmission is disconnected from the radiator 22. In this preferred embodiment, line 24 is the discharge line from the transmission. This means that the transmission fluid is discharged from the transmission via line 24, and the flow and pressure associated with this discharge is determined by the parameters of pump 28 inside the transmission. In practice, the first adapter hose 24 and the second adapter hose 34 are part of the device of the present invention and have a quick-fit connector 32 at the corresponding end. These quick-fit connectors are readily available on the market,
It can be fitted in a predetermined position. When these connectors are disconnected, the disconnected ends are closed to prevent the outflow of fluid from connector 32. Connector 3
2 is connected to the outlet 29 of the transmission and the inlet 27 of the radiator 22 to allow fluid to flow from the transmission to the radiator 22 via the device of the present invention.

Turning now to the device 26 of the present invention, the conduit 38 can be selectively switched to the conduit 40 or the conduit 4.
2, a two-position switch 36 is provided. When the switch is in “position 1” (
When in flushing, line 38 is connected to line 40 and additive reservoir 4
4 input unit. Additive reservoir 44 is configured such that additive is introduced from reservoir 44 into the transmission and radiator system. Reservoir 44
Is connected to the second adapter hose 34. Additives may be added to the transmission fluid in any of a number of commercially available products to either clean the transmission with the fluid or to coat the interior of the transmission 20 and radiator 22 with the additive. Alternatively, another "processing" is performed. Due to the operating internal pressure of the pump 28 of the transmission 20, the transmission fluid passes through the lines 24, 38, 40 and through the additive reservoir 44,
Further, the air returns to the transmission 20 through the radiator 22 through the pipes 46, 48, and 34. This causes all fluid in the transmission to be exchanged and treated with additives. The additive is introduced into all parts of the transmission and the radiator, and the entire system is completely flushed with the used additive transmission fluid.

The fluid containing the additive circulates through the system for at least 5 minutes to allow complete reaction between the additive and the interior of transmission 20 and radiator 22. During this work phase, the operator can observe the fluid passing through the flexible conduit 24 via the viewing window 31 which is a transparent part inserted in the conduit 24. The transparent portion may include a plastic portion or a glass portion that is continuous with the conduit 24.
A similar viewing window 33 is also interposed in the conduit 34. Switch 36 is switched from its first position (where line 40, additive reservoir 44, and line 46 are in the circuit) to a second position connecting line 38 to line 42. The viewing window allows a user of the device of the present invention to view the color of the transmission fluid.
This color is indicative of the reaction of the transmission fluid with the additives during the first stage of the method flushing and the second stage of transfer and exchange of the fluid from the transmission. By observing the window, the user can observe the color of the fluid discharged from the transmission and the color of the fluid introduced into the transmission. The user can therefore know when the cycle has reached its rest point.

The transmission fluid exchange device 50 provides a device for introducing fresh transmission fluid into the transmission while removing spent transmission fluid from the transmission circuit, ie, the transmission 20 and the radiator 22. The transmission fluid exchange device 50 includes a reservoir having a first compartment or chamber 52 and a second compartment or chamber 54, each chamber comprising:
The volume is variable according to the position of the wall portion 56 with respect to the partition wall 59. The specific configuration of this device is described further below. In the case of the invention shown in FIG. 1, it can be seen that as wall 56 moves counterclockwise, compartment 54 increases in volume while compartment 52 decreases in volume. As fluid enters the compartment 54 through the lines 24, 38, 42, the wall 56 is forced to the transmission fluid pressure in the line 42 due to the pressure generated by the pump 28 in the transmission, Turn counterclockwise. As wall 56 moves, the transmission fluid in compartment 52 is forced to pass through lines 58, 48, 34 and into radiator 22 and then back through line 30 back to transmission 20. .

The wall 56 pivots about a central axis 60, which has an associated device 62 (FIG. 5) that indicates the pivot position of the wall 56, thereby allowing the chamber 52 to move from the transmission circuit. The amount of fluid transferred to is displayed. Referring to FIGS. 5 and 1, the wall 56 and the central axis 60 have an associated sensor 62, which indicates the physical position of the wall 56 with respect to the sections 54 and 52. Sensor 62 thus indicates the amount of fluid in compartment 52, and thus the amount of fluid removed from compartment 52 and flowing into transmission 20 and radiator 22. Different transmissions carry different volumes of fluid ranging from about 6.6 liters to about 14.2 liters (7-15 U.S. quarts).

As described below, a user of the present invention introduces a predetermined amount of fresh transmission fluid into chamber 52 before or after connecting the device of the present invention to a vehicle. can do. The device of the present invention is connected to the vehicle when the engine stops. If fluid is introduced into the chamber 52 after the apparatus of the present invention is connected to the vehicle, the engine is shut down during this portion of the cycle of flushing and transferring fluid from the transmission circuit. In fact, during this time, no engine is needed in the system. Because the device of the present invention can be filled and readily used for flushing and transferring transmission fluid. This “fill” means that the chamber 52 is filled with fresh fluid, the chamber 54 is emptied, and the fluid from the chamber 54 is
2 and 24b (indicated by the broken line in FIG. 1), and is discharged to the external reservoir 70 through the conduit 24b. The line 24 is disconnected from the transmission 20 and is connected to the waste liquid reservoir 70 as shown by a broken line 24b.

The filling of the chamber 52 is performed by a device that fills the reservoir 50 and especially the chamber 52. The refill line 64 may be connected by a user or may be permanently connected to a new transmission fluid reservoir 66 for introduction of transmission fluid from the reservoir to the chamber 52. The first is that the new transmission fluid introduced into the device of the present invention is supplied to the reservoir 66
When under pressure within, connecting line 64 to the reservoir, fluid in reservoir 66 is forced into chamber 52 via lines 64, 72, 48, 58 without the need for pump 68. Will be sent to you. In this case, the fluid flows through the pipe 64, the pipe 72, the flow regulating valve 74, the pipe 48, and the pipe 58, and flows into the chamber 52. At this point in the process, line 34 is not connected to radiator 22. When the connector 32 (line 34) is disconnected from the radiator, the connector is automatically closed. Connectors of this type are readily available on the market. When the quick disconnect coupler is connected, it is open to the fluid flow; when not connected to the fitting, it is closed to the fluid flow.

In the case of the second device, which fills the new fluid reservoir 50, the user can
Is connected to a reservoir 66, and a pump 68 transfers transmission fluid from the reservoir 66 to the line 6.
4 and 58 are fed to the chamber 52. When fluid is pumped into the reservoir 52, the fluid pressure causes the wall 56 to move or swivel in a clockwise direction so that the spent fluid is removed from the chamber 54 by the conduits 42, 24 (dashed line 24b )
And discharged to the waste liquid reservoir 70. Chamber 54 in any of the previously described forms
Prior to fluid removal from the chamber and filling of the chamber 52, the user must
Line 2 must be disconnected from the transmission by 2 and line 24 must be connected such that spent transmission fluid flows into waste reservoir 70. This is indicated by the dashed line 24b in FIG.

By disposing the flow control valve 74 in the conduit 72, the fluid under pressure from the reservoir 66 can be filled into the chamber 52 through the conduits 72, 48, 58. As a safety measure, a pressure-controlled flow regulating valve 76 is arranged in the line 58 and the line 4
2 is provided with a pressure-controlled flow regulating valve 78, whereby the line 5 is controlled.
8 or the internal pressure of the line 42 is a predetermined limit value, for example, about 52.7 kg / cm ² (
If the pressure exceeds 75 psi), the excess pressure is released and the oil remaining in line 58 or line 42 passes through lines 81, 83, 85 to the safety reservoir 8.
Drained to zero and the reservoir is eventually drained or emptied via valve 82. A pressure-sensitive valve 84 is disposed in the pipe 39 between the pipe 38 and the pipe 48.
When the internal pressure of the line 39 exceeds the pressure limit of the pressure-sensitive valve 84, the fluid in the line 38 passes through the line 39 and the pressure-sensitive valve 84, enters the line 48, and communicates with the radiator 22 and the transmission. Start cycle through 20.

FIG. 9 shows a perspective view of the transmission flushing and transfer device. Filling line 64 is shown in the storage position. That is, line 64 is not connected to a new transmission oil source for fluid introduction into chamber 52. Line 24 helps to circulate spent transmission fluid to flushing device 26, while line 34, after passing the transmission fluid through radiator 22, as shown in FIG. To return to the transmission 20 to complete the cycle. If the device of the present invention is not used, the lines 24, 34, 64 are all retracted into the device housing of the present invention. FIG. 3 shows a radiator to which the device of the present invention is connected. If the device of the invention is not connected to a radiator, line 24a is connected to the radiator at 27. Line 24a is connected to line 34 of the device of the present invention when disconnected from radiator 22. The embodiment shown in FIG. 3 is a case where the device of the present invention is connected to a radiator and a transmission, as also shown in FIG.

FIGS. 4, 5 and 6 show the reservoir 50 in detail. FIG. 4 shows the reservoir 50 with the top 86 (FIG. 5) removed, partially cut away. The partition wall 59 is fixedly disposed inside the reservoir between the axis 60 of the reservoir and the outer wall 88. The partition wall 59 is a bolt 90 (FIG. 5) fastened to the female receptacle 92 shown in FIG.
Thus, it is fixed to the outer wall 88 of the reservoir 50. The partition gasket 94 is
, The outer wall 88 of the reservoir 50, the top 86 (FIG. 5), and the shaft 6
0 and the bottom 96 form a secure seal. Bottom 96 and top 86 have projecting surfaces that match the diameter of reservoir 50. Projecting bottom surface 98 of bottom 96
Is engaged or inserted inside the outer wall 88 of the reservoir 50, as best seen in FIG. 5 and FIG. 7, which is an exploded view of the reservoir 50. Projection surface 99 of top 86
Are inserted downward into the outer wall 88 of the cylindrical body 50 called the reservoir 50.

Referring to FIGS. 4 and 7, the wall 56 is permanently connected to the shaft 60. The shaft 60 has reduced diameter portions 102 at both ends, and the ends are fitted into holes 104 provided in a top portion 86 and a bottom portion 96. The wall gasket 100 has a collar 106 at each end, as shown in FIG.
02 is located around the reduced diameter portion. The gasket 100 fits in place into the top, bottom, and outer ends of the wall 56, and these portions of the wall 56 define a projecting surface 99 of the top 86 of the cylindrical reservoir 50, A projecting surface 98 of the bottom 96,
It is positioned so as to be applied to the inner surface of the outer wall 88. This forms a seal that prevents fluid leakage. 1 and 6, new fluid is introduced into the chamber 52 via line 58, and as the chamber is filled, the pressure of the incoming fluid causes the wall 56 to pivot counterclockwise. As indicated by the dashed line in FIG. 1, line 24b is connected to waste reservoir 70 and when new fluid flows into chamber 52, the movement of wall 56 causes the fluid in chamber 54 to flow through lines 42, 38, 24. It is discharged through.

When the chamber 54 is empty and the chamber 52 is filled, the stopper 110
The outlet 112 (FIG. 4) in communication with line 42 is closed, stopping further drainage of fluid from the chamber. When the fluid is introduced from the transmission 20 into the chamber 54, the stopper 110 is pushed up by the pressure of the fluid, and the fluid can flow into the chamber 54 from the transmission 20. When fluid from the transmission 20 flows into the chamber 54 and out of the chamber 52 via lines 58, 48, 34 to the radiator 22, the device is in a transfer mode in which spent fluid is removed. As the transmission 20 is discharged from the transmission 20 to the chamber 54 via lines 24, 38, 42, new transmission fluid is supplied to the chamber 5
2 to the transmission circuit. When the transmission circuit is in this mode, switch 36 is set to transfer mode. Reservoir 50 thus introduces fluid into the transmission circuit from which fluid is removed at a precise rate. In other words, exactly the same amount of fluid as is introduced into the transmission circuit is removed from the transmission circuit.

Similarly, as chamber 52 approaches empty, stopper 114 closes outlet 118 and stops further drainage of fluid from reservoir 52. Fresh transmission fluid is routed through line 58 and pushes stopper 114 up into chamber 52. Referring to FIG. 4, the partition wall 59 has notches in the first chamber and the second chamber above the fluid outlets 118 and 112. This allows stoppers 110 and 114 to close the outlets 112 and 118, respectively, and the wall 56 pivots from one extreme position to the other extreme position, thereby effectively emptying the fluid in the chambers 52 and 54. Can be Stopper 110 and stopper 114 are fixedly disposed near the bottom of wall 56 and are positioned such that the stopper can cover outlets 112 and 118, respectively.

Referring to FIGS. 4 and 5, it can be seen that the entire reservoir 50 is assembled by fixedly positioning the septum 56 with bolts 90 against the outer wall 88 of the reservoir 50. The shaft 60 is integral with the wall 56 and is received in the hole 104 in the bottom 96 and the top 86 is positioned to receive the reduced diameter portion 102 of the shaft 60 so that the partition 56 and the wall 56 Are fixedly positioned in the reservoir 50. In order to hold the top 86 and the bottom 96 in a fixed position and to pivotally mount the wall 56 inside the reservoir 50 to define the chambers 52, 54, cylindrical rods 114 are bolted. The top 86 is arranged to be fixedly connected to the bottom 96 by 116. Bolts 116 thread the top 86 and bottom 96 to opposite ends of rod 114.

FIG. 2 shows another embodiment of the present invention. In this embodiment, switch device 36a includes a commercially available programmable switch device that is readily available. By programming a special purpose computer controlled switch device,
The user may connect the line 38 to the line 41, then connect the line 38 to the line 40, then connect the line 38 to the line 42, and then connect the line 38 to the line 41. And the amount of time to complete the cycle can be predetermined.
The different times each stage takes to operate depends on the specific vehicle used, the amount of additives,
During the time required for the additive to circulate through transmission 20 and radiator 22, spent fluid is forcibly removed from the transmission circuit and sent to chamber 54, and new fluid is introduced from chamber 52 to the transmission circuit. It can be predetermined based on time. The term "transmission circuit" refers to the normal fluid path from transmission 20 through radiator 22 back to transmission 20.

While those skilled in the art can utilize different embodiments to provide selective switching, three-position switches 36a that are readily available on the market when a transmission circuit is connected to the device of the present invention. This allows the flushing and transfer cycle to be performed automatically and the switch to return to a position where fluid is circulated from the transmission 20 to the radiator 22. When switch 36a is in the first position, line 38 is connected to lines 41, 48, 34 returning to radiator 22. With this connection, the motor vehicle can be driven after the device according to the invention has been connected to the transmission circuit and also before the flushing cycle has been activated. A flushing cycle occurs in the case where the additive 44 is added to the transmission fluid. Thus, rotation of the engine can take place before and after the flushing and transfer cycle is initiated, and while the apparatus of the present invention is connected to the transmission circuit.

In use, the line 24 a connecting the radiator 22 to the transmission 20 is normally disconnected (FIG. 2), the line 24 is connected to the transmission 20, and the line 34 is connected to the radiator 22. When the device is connected in this manner, transmission fluid can flow from the transmission to the radiator as if the line 24a had not been disconnected. Failure of the programmable switch device 36a may cause fluid to flow from the transmission 20 to the radiator 22.
In the event that the engine is running when it cannot flow through the device of the present invention, the increased pressure is released via line 39 by the pressure sensitive valve 84. Upon activation of the programmable switch device 36a, the apparatus or method of the present invention proceeds and completes automatically and predictably. In that case, as in the case before turning off the engine of the vehicle, disconnecting the pipeline 24 and the pipeline 34 and flushing the transmission,
The pipeline 24a is connected so that the transmission 20 of the vehicle directly communicates with the radiator 22.
