Description

Oil return system for torque converter

The present invention relates to an oil recovery system of a performance test equipment of a torque converter, and more particularly, when the oil filled in the torque converter is discharged to the outside after the performance test is completed, it is forcedly discharged using not only pneumatic pressure but also vacuum pressure. At the same time, the torque converter is inverted and rotated at an angle to the oil recovery system of the torque converter that greatly increased the oil discharge.

In general, the torque converter is installed between the engine of the vehicle and the transmission to transfer the driving force of the engine to the transmission using a fluid.

The torque converter includes an impeller rotating by receiving the driving force of the engine, a turbine rotated by oil discharged from the impeller, and a reactor for increasing the rate of torque change by directing the flow of oil flowing back to the impeller in the direction of rotation of the impeller. Include.

The torque converter may have a damper clutch, which is a means for directly connecting the engine and the transmission because a load applied to the engine may decrease, and the damper clutch is disposed between the front cover and the turbine directly connected to the engine. It allows the engine's rotational power to be transmitted directly to the turbine.

Such a damper clutch includes a piston that is axially movable in the turbine shaft. The piston is engaged with a friction material which is in friction contact with the front cover. The piston is fitted with a torsional damper capable of absorbing shock and vibration acting in the direction of rotation of the shaft when the friction material is engaged with the front cover.

The torque converter configured as described above is manufactured, and after performing a predetermined performance test, the product is shipped. Particularly, after filling the torque converter with oil and performing other performance tests such as water leakage, the filled oil is externally supplied. Must be discharged.

Therefore, in the related art, the oil filled in the torque converter is forcedly discharged by using pneumatic pressure. In this case, the internal structure of the torque converter is complicated, so that the filled oil is not discharged by the structure.

In general, even after oil discharge, 300 to 400 cc of oil remains in the torque converter, resulting in a production cost increase due to a performance test due to relatively expensive oil costs.

The present invention has been made to solve the above problems, the object of the present invention is to discharge the oil filled in the torque converter after the completion of the performance test to the outside, by forcibly discharging by using a vacuum pressure as well as pneumatic At the same time, the torque converter is turned over and rotated at an angle to provide an oil recovery system of the torque converter that greatly increases the oil discharge.

There is an oil discharge valve 26 is further configured.

The operation of the present invention torque converter oil recovery system configured as described above will be described with reference to FIGS. 3A to 3D and FIG. 4.

First, the torque converter 20 is seated in the cradle 12 of the tray 11 through the transfer means not shown as shown in FIG.

The oil is already filled in the torque converter 20 seated on the holder 12 of the tray 11.

When the torque converter 20 is seated on the tray 11 as described above, as shown in FIG. 3A, the holder 11 is raised so that the inlet 44 of the oil recovery part 40 is the inlet of the torque converter 20. (21) It is inserted into the interior and at the same time the binding portion 43 is to be bound around the inlet portion (21).

When the tray 11 is raised and the torque converter 20 is coupled to the oil recovery portion 40, the cylinder portions 31 and 31 'are operated as shown in FIG. 3B to operate the arm portions 32 and 32'. By moving the lower fixing portion (33) (33 ') is fixed to support both sides of the torque converter (20).

And the cradle 11 is lowered as shown in Figure 3c is returned to its original position.

When the operation is completed, the oil discharge operation filled in the torque converter 20 is started.

That is, as shown in FIG. 5, the air supply opening and closing valve 24 is opened and air is supplied through the air supply pipe 48.

The air provided through the air supply pipe 48 is injected into the torque converter 20 through the inlet 44 therein through the inlet 46 formed in the upper end 45 as shown in FIG.

The air discharged through the injection part 44 pushes the oil filled in the torque converter 20, and the oil fills the space between the injection part 44, the binding part 43, and the insertion part 42. Discharged through the outlet 47 formed in the fixing portion 47, the oil discharged to the outlet 47 is introduced into the storage tank 22 through the oil outlet 49 connected thereto.

In addition, the recovered oil introduced into the storage tank 22 is discharged to the outside by opening the oil discharge valve 25.

After the oil discharge is maintained for a predetermined time, the air supply opening and closing valve 24 is closed to block the supply of air, and then the vacuum suction unit 23 is operated. At this time, the oil discharge valve 25 is closed.

Therefore, the storage tank 22 is in a vacuum state, and the pressure sucks and discharges the oil remaining in the torque converter 20 through the oil discharge pipe 49 at a vacuum pressure.

The oil discharged by the vacuum pressure is discharged to the outside through the storage tank 22 and the oil discharge valve 26.

As described above, the present invention can greatly reduce the remaining oil remaining amount by discharging the oil of the torque converter 20 using the vacuum pressure.

While the oil recovery operation is performed as described above, the circular plates 15 and 15 'are rotated 180 ° about the hinge shafts 14 and 14' so that the mounting portion 30 is reversed as shown in FIG. 3D. The torque converter 20 is also turned upside down so that the upper and lower positions are changed.

Then, the circular plates 15 and 15 'are pivotally rotated by a predetermined time at a predetermined angle (for example, 35 ㅀ) around the supports 13 and 13'.

This operation is to increase the oil discharge effect by inverting the torque converter 20 and then shaking the oil filled therein quickly to the inlet portion 21 in the complex structure therein.

When such an operation is performed for a predetermined time and the oil recovery operation is completed, the circular plates 15 and 15 'are rotated 180 ° again so that the torque converter 20 reaches a position as shown in FIG. 3C. As shown in FIG. 3B, the tray 11 is raised to support the torque converter 20.

After that, as shown in FIG. 3A, the two fixing parts 33 and 33 ′ are released from the torque converter 20 to return to their original positions, and then the tray 11 is lowered to complete the oil recovery process of the torque converter 20. Will be.
