Referring to FIG.

First, the structure of the hinge-movable oil supply apparatus according to an embodiment of the present invention will be described with reference to FIG. The present embodiment describes a hinge-movable oil supply device applied to a transfer (auxiliary transmission), but is not limited thereto and is applicable to a transmission or the like.

The case 100 forms an outer shape for accommodating a plurality of gears 200 therein, and is generally made of cast iron or aluminum. A connection unit for fixing to the transmission may be formed on one side of the case 100.

In the case 100, a plurality of gears 200 are provided and connected to the shaft, and the shaft is connected to the transmission to receive power from the transmission to operate the plurality of gears 200. The plurality of gears 200 serve to transmit the transmitted power to the wheels.

The plurality of gears 200 includes an input gear 210, an idle gear 220, and a front gear 230. The input gear 210 is coupled to a shaft for receiving power from the transmission and receives power from the transmission to transfer the power to the idle gear 220. In this embodiment, the input gear 210 is rotating counterclockwise.

The idle gear 220 is disposed between the input gear 210 and the front gear 230. The idle gear 220 can not change the power of the idle gear and adjusts the position or changes the direction of rotation. In the present embodiment, the idle gear 220 rotates in a clockwise direction opposite to the rotation direction of the input gear 210. [ The front gear 230 receives power from the idle gear 220 and transmits the power to the axle. In the present embodiment, the front gear 230 rotates counterclockwise.

The oil guide 300 is connected to one side of the case 100 by a hinge 320 and is connected to the corresponding position between the input gear 210 and the idle gear 220 in the present embodiment. Since the oil guide 300 is connected to the hinge 320, the oil guide 300 can rotate about the hinge and can be easily moved. The oil guide 300 generally has a shape of a long rod and serves to guide the oil to flow.

The position of the oil guide 300 may be set to a neutral position (Position 1) and a position (Position 2, Position 3) for transmitting oil to each gear. The oil guide 300 is disposed between the input gear 210 and the idle gear 220 so that the oil guide 300 is positioned between the input gear 210 and the idle gear 220, 4, the position where the oil guide 300 is biased toward the input gear 210 is referred to as a first position (Position 2), and as shown in FIG. 4, The position where the first gear 300 is biased toward the idle gear 220 is referred to as a second position (Position 3).

The motor for hinge is for moving the position of the oil guide 300 by applying a voltage, and an actuator or the like can be used. The hinge motor is controlled by a control unit such that a motor voltage CW for rotating the oil guide 300 toward the input gear 210 or a motor voltage CCW for rotating the oil guide 300 toward the idle gear 220 .

The control unit controls the motor for the hinge to adjust the position of the oil guide 300. The control unit controls the hinge motor to apply the motor voltage CW for rotating the oil guide 300 toward the input gear 210 or the motor voltage CW for rotating the oil guide 300 toward the idle gear 220. [ (CCW) is applied. The control method of the hinge-movable oil supply apparatus of the present invention by the control unit will be described below.

The plurality of temperature sensors 400 are installed at the center of each gear, and are generally temperature sensors capable of measuring the oil temperature. The first temperature sensor 410 and the second temperature sensor 420 are installed at the center of each of the input gear 210 and the idle gear 220. However, May be installed. The first temperature sensor 410 may measure the temperature of the input gear 210 and the second temperature sensor 420 may measure the temperature of the idle gear 220. The measured temperature is transmitted to the control unit.

The control unit controls the position of the oil guide 300 according to the temperatures of the gears measured by the plurality of temperature sensors 400. A specific control method thereof is described below with reference to FIG. .

First, the temperature of each gear is measured by a plurality of temperature sensors 400 (S1100). The measured temperature information is transmitted to the controller, and the controller compares the temperature of each gear (S1200). Next, the controller controls the hinge motor according to the comparison result, and adjusts the position of the oil guide 300 by applying a voltage (S1300).

In this case, if the temperatures of the gears are the same, a step S1310 of checking the position of the oil guide at the present time to adjust the position of the oil guide 300 according to the comparison result, A step of applying a voltage (S1320) is performed.

On the other hand, if the temperature of each gear is not the same, a step S1330 of applying a motor voltage to adjust the position of the oil guide 300 is performed according to the comparison result.

In the present embodiment, the temperatures of the input gear 210 and the idle gear 220 are measured by the first temperature sensor 410 and the second temperature sensor 420 (S1100). This is transmitted to the control unit for comparison. First, it is checked whether the temperature of the input gear 210 is equal to the temperature of the idle gear 220 (S1210). If the temperatures of the input gear 210 and the idle gear 220 are equal to each other, it is determined whether the oil guide 300 is in the neutral position (Position 1) (S1312). Accordingly, if the oil guide 300 is set at the neutral position, it is not necessary to adjust it, so that the control unit does not apply the voltage to the hinge motor. However, if the oil guide 300 is not set at the neutral position, it is checked whether the oil guide 300 is in the first position (Position 2) (S1314). If the oil guide 300 is set to the first position (Position 2), the control unit causes the hinge motor to apply the motor voltage CCW for rotating the oil guide 300 toward the idle gear 220, The guide 300 is adjusted to the neutral position. If the oil guide 300 is set to the second position (Position 3), the control unit causes the hinge motor to apply the motor voltage CW to rotate the oil guide 300 toward the input gear 210 The oil guide 300 is similarly adjusted to the neutral position.

Alternatively, if the temperatures of the input gear 210 and the idle gear 220 are not the same after the step S1210 of confirming that the temperature of the input gear 210 is the same as the temperature of the idle gear 220, (S1220) to check whether the temperature of the gear 210 is higher than the temperature of the idle gear 220. [ Accordingly, when the temperature of the input gear 210 is higher than the temperature of the idle gear 220, the control unit controls the input gear 210 and the input gear 210 so that the hinge- The oil guide 300 is adjusted to the first position (Position 2) by applying the motor voltage CW for rotating the oil guide 300 to the first position. On the other hand, if the temperature of the idle gear 220 is higher than the temperature of the input gear 210, the idle gear 220 is required to be intensively lubricated and cooled, so that the hinge motor is driven toward the idle gear 220 The oil guide 300 is adjusted to the second position (Position 3) by applying the motor voltage CCW for rotating the oil guide 300.

Accordingly, there is an effect that efficient lubrication and cooling can be performed as the oil flows intensively to the gears having a higher temperature among the plurality of gears. In addition, it is possible to supply a sufficient amount of oil even when a large amount of oil is not required, thereby improving lubricity.
