Abstract

PURPOSE:To obtain the characteristics of a clutch assuming a usual use time by rotationally driving the clutch on one side thereof and connecting the clutch to increase the speed thereof on the other side thereof. CONSTITUTION:A dynamic motor 4 on an input side is connected to a jig head H having a transmission clutch C built therein through a gearbox 6 and a torque meter 8. A motor on an output side is also constituted in the almost same way. A hydraulic type joint-disjoin actuator 50 is constituted of the clutch drum 46 on the input side of the clutch C, the hydraulic chamber 49 thereof and a clutch piston 47 to perform the joint-disjoin operation of the clutch C. The motor 4 holds the clutch C to a predetermined number of rotations on the input side thereof by a CPU and, when the actuator 50 connects the clutch C, the clutch C is increased in speed on the output side thereof along with an inertial body 21. Since the input and output of the clutch C generates a rotational change in the same way at the time of use, centrifugal oil pressure is generated in the actuator 50 in the same way at the time of actual operation. Therefore, the transmission torque at the time of the connection of the clutch can be reproduced in the same way at the time of an on-vehicle state.

Field of the Invention The present invention relates to a clutch testing device, for example, a device for testing a speed change clutch and the like installed in an automatic transmission for a vehicle, which is used for various tests of dry or wet clutches. It is possible.

[0002]

2. Description of the Related Art As a conventional clutch testing device of this type, there is a shifting clutch testing device used in an automatic transmission for a vehicle as shown in FIG. As is well known, this speed change clutch is installed in an automatic transmission together with a planetary gear mechanism, and the engagement and disengagement of the planetary gear mechanism is switched by the connection and disconnection (hereinafter simply referred to as "disconnection / connection") operation, This is for shifting the transmission.

FIG. 21 is a front view showing the schematic construction of the conventional clutch testing apparatus.

As shown in the figure, a bearing member 202 is installed at the center of the base 201 of the test apparatus, and the bearing member 2
On the right side of 02, the jig head 2 accommodating the transmission clutch C
03 is fixed. A drive motor 204 is installed on the left side of the base 201, and an output shaft 204a of the drive motor 204 is connected to one end of an input shaft 206 via a flywheel 205. Input shaft 2
06 is rotatably supported by the bearing member 202, and the other end of the input shaft 206 is the clutch drum 207 which is the input side of the speed change clutch C in the jig head 203.
Are linked to. The regulating member 20 is provided at the right end of the base 201.
8 is erected, and the restricting member 208 serves as the output shaft 20.
The clutch hub 210, which is the output side of the speed change clutch C, is connected via 9 to restrict the rotation of the clutch hub 210.

The clutch drum 20 of the shift clutch C
7, a clutch piston 211 is arranged so as to be movable in the axial direction, and a portion defined by the clutch piston 211 in the clutch drum 207 serves as a hydraulic chamber 212. A clutch disc 213 is supported by the clutch hub 210, and the clutch disc 213 faces the clutch piston 211. As is well known, the clutch disc 213 is configured by attaching a facing 213a to a ring-shaped core metal 213b, and frictional force is generated by the facing 213a.

A hydraulic circuit (not shown) is connected to the hydraulic chamber 201a, and the hydraulic circuit 201a is connected to the hydraulic circuit.
Automatic transmission installed in
The hydraulic pressure of fluid (hereinafter, simply referred to as “ATF”) moves the clutch piston 211 to press or release the clutch disc 213, and as a result, the speed change clutch C is operated to be connected or disconnected.

Next, the operation of the conventional clutch testing apparatus configured as described above will be described.

In the test, first, the shift clutch C is disengaged by the hydraulic circuit, and the drive motor 204 drives the flywheel 205 together with the clutch drum 207 of the shift clutch C.
Is controlled in a specific direction, for example, 3000 rpm as a target rotation speed. Next, when the connection of the shift clutch C is started in the hydraulic circuit, the rotation speed of the clutch drum 207 on the input side gradually decreases with slip, and finally becomes 0, and the clutch C is completely connected. . Thereafter, the connection and disconnection of the clutch C are similarly repeated, and when the number of repetitions reaches, for example, 15,000, the test is ended.

During the test, each time the shift clutch C is engaged, the torque meter changes the transmission torque (transmission between the input side and the output side of the clutch between the start and the disengagement of the clutch). The change in the transmitted torque) is detected, and data is collected on how the change in the transmitted torque changes as the test progresses. After the test, the wear and separation of the facing 213a of the clutch C are observed, and the durability and properness of the material of the facing 213a are checked based on the observation result and the above-mentioned transmission torque data. Making a decision.

[0010]

In the conventional clutch testing device, the output side of the speed-changing clutch C whose rotation is restricted as described above is forcibly stopped on the rotating input side, so that the load on the clutch C is reduced. Is configured to add.
However, as is well known, the rotation speed of the output side of the speed change clutch C when actually installed in the automatic transmission of the vehicle is not regulated, and the output side of the speed change clutch is raised to the input side speed by the clutch connection. The phenomenon is occurring. As described above, the rotational change of the input and output of the speed change clutch C is different between the time of actual vehicle mounting and the time of testing, and if attention is paid to the input side, it will be maintained at about 3000 rpm when mounted on the vehicle, while it will be maintained at 3000 rpm during testing. It will be reduced to 0. Therefore, the hydraulic pressure generated by the centrifugal force in the hydraulic chamber 212 on the input side (hereinafter simply referred to as "centrifugal hydraulic pressure")
Even though the clutch is maintained at a substantially constant value from the start to the end of clutch engagement when mounted on the vehicle, it gradually decreases as the rotational speed on the input side decreases during the test. The connection pressure of the vehicle will also differ between when it is mounted on the vehicle and when it is tested.

Therefore, as described above, the transition of the transmission torque collected during the test and the facing 213a after the test are performed.
The wear and the peeled state, etc., which occurred in the above-mentioned situation are different from those in the case of actual vehicle installation, and there remains a problem that an accurate determination cannot be performed.

[0012] Therefore, an object of the present invention is to provide a test device for a clutch which can carry out a test corresponding to an actual use condition and can obtain the characteristics of the clutch on the assumption of normal use.

[0015]

According to the present invention, when one side of the clutch is held at a predetermined rotation speed by the rotation driving means and the clutch is connected by the connection / disconnection driving means in this state, the other side increases together with the inertial body. Since the input / output of the clutch changes in rotation like in the actual operation, the centrifugal hydraulic pressure similar to that in the actual operation is generated in the connecting / disconnecting drive means.

According to the second aspect of the present invention, one side of the clutch is held at a predetermined rotational speed by the rotation driving means, and a predetermined amount of braking is applied to the other side of the clutch by the braking means.

And

The main routine of FIG. 12 operates at the same time when the power switch (not shown) is turned on.

Now, when neither the setting start switch 113 nor the test start switch 116 is operated, the CPU 1
41 initializes in step S1, clears all flags and memory to be used, and sets start switch 1 in step S2.
Since No. 13 is not operated, the process proceeds to step S3, and since the test start switch 116 is not operated in this step S3, the process returns to step S2. Therefore, in this case, the setting completion flag is held in the clear state, and the test and the test condition setting process are not executed.

When the test start switch 116 is operated from the above-mentioned state, steps S3 to S4 are performed.
Then, since the setting completion flag is not set in step S4, the process returns to step S2. That is, at this point in time, the test conditions have not been set, so the test will not be performed even if the test start switch 116 is operated.

Further, when the setting start switch 113 is operated from the above-mentioned state, steps S2 to S5 are performed.
Then, the test condition is set, the setting completion flag is set in step S6, and the process returns to step S2. And
After that, when the test start switch 116 is operated, the process proceeds from step S3 to step S4, and the setting completion flag is already set, that is, the test condition is set. Therefore, the process proceeds to step S7 to perform the test. Run. After the test is completed, the end lamp 117 is turned on in step S8 to notify the operator of the end of the test, the process returns to step S2, and this routine is repeatedly executed.

<< Setting Process >> Next, details of the test condition setting process executed in step S5 of the above-mentioned main routine will be described.

It is explanatory drawing which shows the display of the liquid crystal display board in a test device.

When the test condition setting processing routine is called, the CPU 141 displays a message "Please input the heater set temperature Te1" on the liquid crystal display panel 112 in step S11 as shown in FIG. . The worker responds to the message by pressing the numeric keypad 1 in step S12.

141, the process proceeds to step S14, and as shown in FIG. 15, a message "Please input the heater set temperature Te2" is displayed on the liquid crystal display plate 112, and in response to this, the operator sets in step S15. When the temperature Te2 is input and the mode changeover switch 114 is pressed in step S16, the process proceeds to step S17. Next, in step S17, a message "Please input the driving rotation speed Re" is displayed on the liquid crystal display panel 112, and in response thereto, the driving rotation speed Re is input by the operator in step S18, and in step S19. When the mode changeover switch 114 is pressed, the process proceeds to step S20. here,
Both heater set temperatures Te1 and Te2 are 120 ° C,
It is assumed that 3000 rpm is input as the drive rotation speed Re.

Further, in step S20, the liquid crystal display panel 112 is used.
Message "Please input the connection start time Tm1" is displayed, and in response thereto, the worker inputs the connection start time Tm1 in step S21 and presses the mode changeover switch 114 in step S22. Then, the process proceeds to step S23. Then, in step S23, "Enter the braking start time Tm2" on the liquid crystal display panel 112.
Message is displayed, and in response, step S2
When the operator inputs the braking start time Tm2 in 4 and the mode changeover switch 114 is pressed in step S25, the process proceeds to step S26. Then, step S26
Then, the message "Please input the required time Tm3" is displayed on the liquid crystal display 112, and in response thereto, the required time Tm3 is input by the operator in step S27, and the mode changeover switch 114 is pressed in step S28. When operated, the process proceeds to step S29. Connection start time Tm here
15 seconds as 1 and 20 seconds as braking start time Tm2
However, it is assumed that 80 seconds is input as the required time Tm3.

Then, in step S29, the liquid crystal display panel 11
2 displays a message "Please input the number of cycles N", and in response thereto, the number of cycles N is input by the operator in step S30, and the mode changeover switch 114 is pressed in step S31. , The step S1

<< Test Execution Processing >> Next, the details of the test execution processing executed in step S7 of the above-mentioned main routine will be described.

FIG. 16 and FIG. 17 are flow charts showing the details of the test execution processing routine executed by the CPU in the clutch testing apparatus according to the first embodiment of the present invention.
FIG. 19 is a flow chart showing the details of an oil temperature control routine executed by the CPU in the clutch test apparatus according to the first embodiment of the present invention. FIG. 19 is a time chart during the test of the clutch test apparatus according to the first embodiment of the present invention. It is a chart.

As shown in FIGS. 16 and 17, when the test execution processing routine is called in step S7, C
The PU 34 clears the counter n in step S41, executes the oil temperature control of the clutch connecting / disconnecting hydraulic circuit 121 in step S42, and executes the oil temperature control of the heat retaining hydraulic circuit 122 in step S43.

When the oil temperature control routine is called in step S42, as shown in FIG. 18, step S61 is executed.
The actual oil temperature sensor 1 of the clutch connection / disconnection hydraulic circuit 121
The temperature of the ATF detected in 27 is the same as in step S6.
In step 1, it is determined whether the temperature is 120 ° C. or higher, which is set as the set temperature Te1, and if it is 120 ° C. or higher, the heater 124 is kept off in step S62, and if it is lower than 120 ° C., the heater 124 is turned on in step S63. Keep on. Therefore, step S6 of this routine
The heater 124 is controlled to be turned on / off by the processing from 1 to step S63, and the clutch connecting / disconnecting hydraulic circuit 121 A
The temperature of TF is kept at about 120 ° C. which is the set temperature Te1. Although not described in detail, the oil temperature control routine in step S43 has the same control content, and the temperature of the ATF of the heat retaining hydraulic circuit 122 is set to the set temperature T.
It will be maintained at about 120 ° C, which is e2.

As a result, the speed change clutch C under test is supplied to the jig head H from the heat retaining hydraulic circuit 122.
Hydraulic circuit 1 for clutch connection / disconnection at TF and clutch connection / disconnection
The ATF supplied from 21 always keeps the temperature at about 120 ° C., that is, the same temperature as when the vehicle is actually mounted.

After that, as shown in FIG. 16 and FIG.
In step S44, it is determined whether or not the counter n has reached 15000, which has been set as the cycle number N in step S30. Since it has not yet reached, the process proceeds to step S45. Then, in step S45, the switching valve 131 of the clutch connecting / disconnecting hydraulic circuit 121 is switched to stop the supply of ATF from the hydraulic pump 126 to the speed change clutch C. As a result, the pressure in the hydraulic chamber 49 of the speed change clutch C decreases, the clutch piston 47 of the connecting / disconnecting actuator 50 moves leftward by the urging force of the return spring 48, and the pressure contact of the clutch disc 100 is released. Therefore, as shown in FIG. 19, the shift clutch C is held in the disengaged state.

Next, in step S46, the shifting cylinder control valve 143 switches the shifting cylinder 32 to switch the input side gearbox 6 to the speed increasing position, and in step S47 the gear position detecting sensor 33 outputs When it is determined that the switching to the speed increasing position is completed based on the detected value, the process proceeds to step S48. Further, step S48
The output-side gearbox 12 is switched to the neutral position with, and when it is determined that the switching is completed in step S49, the process proceeds to step S50. Then, when the input side dynamic motor 4 is rotationally driven in a specific direction in step S50, the input side of the speed change clutch C starts to rotate together with the flywheel 21 of the input side mechanism section 1, while the output side is disengaged by the clutch. Since the driving force is not transmitted, the stop state is maintained together with the flywheel 21 of the output side mechanism unit 2 (FIG. 19).
Point a).

Then, in step S51, based on the detection value of the rotation speed sensor 142 of the input side mechanism portion 1, the input side rotation speed of the speed change clutch C becomes 3000 rpm set as the drive rotation speed Re in step S18. It is determined whether or not it has been reached. As described above, since the rotation of the input side dynamic motor 4 is accelerated by the input side gearbox 6, the CPU 141 sets the output side gearbox 6
The detection value of the rotation speed sensor 142 is corrected according to the speed increasing ratio to calculate the actual rotation speed of the shift clutch C on the input side.

If it is determined in step S51 that the input side rotation speed of the speed change clutch C has reached 3000 rpm (point b in FIG. 19), this 300 rpm is determined in step S52.
The rotation speed of the input side dynamic motor 4 is controlled at a constant speed with 0 rpm as the target rotation speed. That is, at this point, there is 3000 rpm between the input side and the output side of the shift clutch C.
This means that there is a difference in rotation. Then, if it is determined in step S53 that 15 seconds set as the connection start time Tm1 has elapsed since the rotation of the input side dynamic motor 4 was started (point c and point d in FIG. 19), step S54 The switching valve 131 of the clutch connecting / disconnecting hydraulic circuit 121 is switched to supply the ATF from the hydraulic pump 126 to the speed change clutch C.

As a result, the pressure in the hydraulic chamber 49 rises,
The clutch disc 100 is crimped by the clutch piston 47 of the connecting / disconnecting actuator 50, and as shown in FIG. 19, the speed change clutch C is switched to the connected state, and the driving force on the input side causes the output side in the stopped state to output side. Mechanism 2
The speed is rapidly increased together with the flywheel 21. In addition,
At this time, the rotation of the input side of the speed change clutch C slightly decreases due to the load on the output side. Then, the input side and the output side at the time of completion of the clutch connection have the same rotation speed of, for example, about 2700 rpm (point e in FIG. 19), and thereafter, by the driving force of the input side dynamic motor 4 which is controlled at a constant speed,
The input / output rotation speed gradually increases and is maintained at 3000 rpm (point f in FIG. 19).

As described above, when the speed change clutch C is connected, the output side in the stopped state is accelerated together with the flywheel 21 by the input side during driving, and the inertial force of the flywheel 21 at the time of speed increase is applied to the speed change clutch C. It will be added as a load. The input / output rotation speed of the shift clutch C at this time is the same as that when actually mounted on the vehicle. Focusing on the input rotation speed, it is only slightly decreased when the output rotation speed is increased. , Maintain an almost constant rotation speed. Therefore, the centrifugal hydraulic pressure generated in the hydraulic chamber 49 on the input side when the clutch is connected is also maintained at a substantially constant value as in the case of vehicle mounting.

Further, in step S55, the CPU 141
When it is determined that 20 seconds set as the braking start time Tm2 in step S24 has elapsed since the rotation of the input side dynamic motor 4 was started (point g in FIG. 19), the input side dynamic motor 4 is determined in step S56.
The torque is changed to the negative side to execute braking. Therefore,
The input / output speed of the speed change clutch C sharply decreases and finally becomes 0 (point h in FIG. 19), and step S57
When it is determined that 80 seconds set as the required time Tm3 has elapsed since the rotation of the input side dynamic motor 4 was started, the counter n is incremented by "+1" in step S58, and the process returns to step S42.

With the above processing, one cycle is completed, and the shift clutch C is connected while consuming the inertial force of the flywheel 21 while driving the input side and stopping the output side. Then, at the time of connection, the torque transmitted from the input side to the output side of the speed change clutch C changes as shown in FIG. 19, and the transmitted torque is detected by the torque meters 8 and 14 and displayed on the display or. It is collected in various forms such as printouts.

On the other hand, the CPU 141 executes the above step S42.
And the oil temperature control is executed in step S43, and step S4
Since the counter n is still 1 in 4 and has not reached 15000 set as the number of cycles N, the processes of step S45 and subsequent steps are repeated again. Then, this series of cycles is repeated 15,000 times, and when the counter n reaches the number of cycles N in step S44, it is determined that the test is completed, the end lamp 117 is turned on in step S8 shown in FIG. 12, and the process returns to step S2.

In the above-mentioned test, the heater set temperatures Te1 and Te2 are set to 120 ° C. and the drive speed Re is set to 3000 rpm, and the connection start time Tm is set.
15 sec as 1 and 20 se as braking start time Tm2
c is the required time Tm3 is 80 sec and the number of cycles is N
Although 15,000 times are set respectively, these set values can be arbitrarily set according to the specifications of the shift clutch C.

Further, the drive rotational speed Re can be set to either positive or negative, and in a normal test, the drive rotational speed Re is set so that the input side rotational direction of the speed change clutch C coincides with the actual engine driving direction. Although the polarity of Re is set, the polarity can be reversed and the input side of the clutch C can be rotationally driven in the direction opposite to that in the vehicle. Then, even when the input side is rotated in the reverse direction in this way, it is possible to generate the centrifugal hydraulic pressure in the hydraulic chamber 49 on the input side, which is the same as when the vehicle is mounted.

As described above, in the clutch testing device of the first embodiment, the input side dynamic motor 4 connected to the input side of the speed change clutch C and the output side mechanism connected to the output side of the speed change clutch C. Part 2 flywheel 21
And the clutch drum 46 on the input side of the speed change clutch C
And a clutch piston 47, which is a hydraulic connection / disconnection actuator 5 for connecting / disconnecting the speed change clutch C.
0, and the speed change clutch C by the connection / disconnection actuator 50.
And the input side dynamic motor 4 drives the input side of the speed change clutch C to rotate at the drive speed Re, and the connection / disconnection actuator 50 connects the speed change clutch C to the flywheel 21 together with the flywheel 21. And a CPU 141 for increasing the speed of the output side of the speed change clutch C.

Therefore, when the clutch is connected,
The rotation speed on the output side is only increased by the input side, and the input side itself maintains a substantially constant rotation speed as when mounted on the vehicle. As a result, the disconnection actuator 50 on the input side
The centrifugal oil pressure generated in the oil pressure chamber 49 is also maintained at a substantially constant value as in the case of vehicle mounting, and the shift clutch C can be connected at the same connection pressure as in vehicle mounting during the test.

Therefore, it is possible to reproduce the transmission torque when the clutch is engaged, or the wear or peeling state that occurs in the facing of the clutch disc 100 after the test as in the case of the vehicle, and the durability of the facing is based on the data. It is possible to accurately determine the appropriateness of the material.

Incidentally, as described above, during the test, not only the input side of the speed change clutch C but also the output side rotation speed changes as in the case of actual vehicle mounting, so that the disconnection / connection actuator 50 is provided on the output side. Even when the variable speed clutch C is tested, it is possible to generate a centrifugal hydraulic pressure similar to that when mounted on a vehicle and make an accurate determination.

<Second Embodiment> FIG. 20 is a hydraulic circuit diagram of a clutch testing device according to a second embodiment of the present invention. The test device for this clutch has almost the same structure as the test device of the first embodiment, and the difference lies in the output side mechanical section 2. Therefore, this difference will be mainly described with reference to FIG.

The output side mechanism portion 2 of the test apparatus is provided with a brake 171 as a braking means.
The rotor 172 is connected to the output side of the speed change clutch C via the output side torque meter 14, the output side fixed bearing 15, the torsion shaft 17 and the output side movable bearing 18. Further, a caliper 173 is provided on the rotor 172, and the caliper 17 is connected to a hydraulic circuit for braking not shown.
When the hydraulic oil is introduced into No. 3, the braking force is applied to the output side of the speed change clutch C via the rotor 172.

When the test of the speed change clutch C is carried out by the test device configured as described above, a predetermined amount of braking force is continuously applied to the output side thereof by the brake 171. Then, similarly to the first embodiment, the speed change clutch C is connected in a state where the input side rotates at the drive rotation speed Re and the output side is stopped, and as a result, the output side of the speed change clutch C is connected by the brake 171 described above. The braking force is rapidly increased against braking, and the braking force is applied to the clutch C at the time of connection. That is, in the second embodiment, the load is applied to the clutch C by using the braking force of the brake 171 instead of the inertial force of the flywheel 21 of the first embodiment.

As described above, the clutch testing device of the second embodiment includes the input side dynamic motor 4 connected to the input side of the speed change clutch C, and the brake 171 connected to the output side of the speed change clutch C. , The shift clutch C
Input side clutch drum 46 and clutch piston 4
7, a hydraulic connection / disconnection actuator 50 for connecting / disconnecting the transmission clutch C, the connection / disconnection actuator 50 to disconnect the transmission clutch C, and the input side dynamic motor 4 to form the transmission clutch C. The input side of is driven to rotate at the drive speed Re, and the brake 1
A predetermined amount of braking is applied to the output side of the clutch C at 71, and the speed change clutch C is connected at the connecting / disconnecting actuator 50 so as to resist the braking of the brake 171.
And a CPU 141 for accelerating the output side of the.

Therefore, when the clutch is connected,
Since the input side of the speed change clutch C maintains a substantially constant rotational speed as in the case of vehicle mounting, it is possible to generate the centrifugal hydraulic pressure in the hydraulic chamber 49 of the connecting / disconnecting actuator 50 on the input side similar to that in the case of vehicle mounting. Therefore, the transmission torque when the clutch is connected,
Alternatively, it is possible to reproduce the wear, the peeling state, and the like, which occur in the facing of the clutch disc 100 after the test, in the same manner as when mounted on the vehicle, and it is possible to accurately determine the durability of the facing and the appropriateness of the material based on the data. it can.

The above embodiment has been embodied as a test device for testing the wet type shift clutch C of an automatic transmission for a vehicle, but the present invention is not limited to this and is not limited thereto. The type of clutch is not limited as long as it is a test device for testing the clutch. Therefore,
For example, it may be embodied as a test device for testing a dry clutch of a manual transmission or an industrial clutch.

Further, the rotation driving means of the above embodiment is constructed as the input side dynamic motor 4, but the present invention is not limited to this, and the input of the speed change clutch C is not limited to this. It is only necessary that the side can be rotationally driven. Therefore, for example, this rotation drive means may be configured as a hydraulic motor.

Further, although the connecting / disconnecting drive means of the above embodiment is constructed as the existing hydraulic connecting / disconnecting actuator 50 provided in the speed change clutch C, it is not limited to this when the present invention is carried out. Instead, it is only necessary that the transmission clutch C can be engaged and disengaged, and the hydraulic clutch is influenced by the centrifugal hydraulic pressure. Therefore, for example, instead of using the connecting / disconnecting actuator 50, a hydraulic type connecting / disconnecting actuator may be provided in the jig head H, and the actuator may be used to connect / disconnect the speed change clutch C.
