Here, the shaft hole of the movable rotary plate 26 has a rectangular cross-sectional structure and is coupled with the motor shaft 2a having the same rectangular cross-sectional structure, so that the rotational torque of the motor shaft 2a can be more easily transmitted do.

The movable rotary plate 26 is pressed against the transmission gear 21 by the elastic force of the return spring 22 and transmits the rotation of the motor 2 to the transmission gear 21 The rotation of the motor 2 is transmitted to the speed reducer 3 by separating from the transmission gear 21 while pulling the return spring 22 by magnetic force when the electromagnetic clutch 23 is operated.

However, it may be implemented in reverse.

4 and 5 show the power separation and transmission state according to the operation or non-operation of the electromagnetic clutch 23 according to the present embodiment.

4 is a power transmission separated state according to the operation of the electromagnetic clutch 23. In this case, the electromagnetic clutch 23 is a worm shaft 4a constituting the reducer 3 by magnetization of the electromagnetic coil 24 by power supply. Magnetic force is formed in the fixed plate 25 connected.

When the movable rotary plate 26 connected to the return spring 22 is pulled by the magnetic force formed on the fixed plate 25 as described above, the movable rotary plate 26 moves down to the fixed plate 25 along the motor shaft 2a, (25).

As a result, the movable rotary plate 26 and the transmission gear 21 are in the separated state Ka so that the rotation of the motor 2 is transmitted to the worm 4a (4a) connected to the fixed plate 25 via the movable rotary plate 26 and the fixed plate 25, And the rotation of the worm shaft 4a is transmitted to the worm wheel 5 through the worm gear 4 to apply a torque to the steering shaft 1a so that the torque of the motor 2 is converted into the steering force.

On the other hand, Figure 5 is a power transmission state according to the non-operation of the electromagnetic clutch 23, in this case, the electromagnetic clutch 23 is no power supply, there is no magnetization of the electromagnet coil 24, thereby moving the rotating plate 26 Pulled by the return spring 22 to maintain a strong fixed state to the transmission gear (21).

As described above, when the electromagnetic clutch 23 is not operated, the connection state Kb is strongly formed by the elastic force of the movable rotary plate 26 and the gear return spring 22, while the movable rotary plate 26 and the fixed plate 25 are separated from each other, so that the rotation of the motor 2 is transmitted to the transmission gear 21.

Accordingly, the power take-off device 30 is switched to the operating state by receiving the power of the motor 2. This is because the rod input shaft 31 engaged with the transmission gear 21 is rotated to rotate the rod shaft 32 together .

The rotation output gear 41 engaged with the inter gear 33 of the rod shaft 32 is rotated by the rotation of the screw shaft 32. As a result, the power output from the power take- (42) are also rotated together.

When the screw shaft 42 is rotated as described above, the rotation of the screw shaft 42 of the tele unit 50 and the tilt unit 60 associated with a pair of bolt screws 42a and 42b formed at intervals from each other, respectively. Can be switched to operation.

6 shows the operation of the tilt unit 60 to implement the tilt up / down according to this embodiment.

As shown, the operation of the tilt unit 60 is driven by the operating state of the electromagnetic clutch 23, the power of the motor 2 is branched to the power connector 20 through the power take-off 30 through the power output unit 40 By being transmitted to, the screw shaft 42 of the power output unit 40 is rotated through the bolt screw 42b portion is caused by the operation associated with the tilt unit 60 is implemented.

At this time, in order to implement the tilt up or tilt down, the teleunit 50 and the tilt unit 60 must be switched to the ready state, respectively.

In this case, Figure 6 (A) is a preparation process for the operation of the tilt unit 60, the tilt solenoid 61 constituting the tilt unit 60 is turned on (On) and at the same time as shown in Figure 6 (b) The tele unit 50 maintains the tele solenoid 51 in an off state.

In this state, when the tilt solenoid 61 of the tilt unit 60 is turned on, it means that the operation associated with the screw shaft 42 of the power output unit 40 occurs, whereas the teleunit 50 By means that the tele solenoid 51 of the (Off) is maintained (Off) means that the operation associated with the screw shaft 42 of the power output unit 40 does not occur.

FIG. 6A illustrates a case in which the tilt solenoid 61 of the tilt unit 60 is turned on to operate in conjunction with the screw shaft 42 of the power output unit 40. In this case, The screw shaft 42 is rotated counterclockwise by the power of the motor 2 transmitted to the output unit 40, and the nut screw 63 coupled to the screw shaft 42 is rotated counterclockwise of the screw shaft 42. It is switched to the state of moving forward to the front (Fig. 6 (a)).

The forward movement of the nut screw 63 as described above is restricted by the tilt solenoid 61 because the moving pin 62 drawn out due to the on of the tilt solenoid 61 is fitted into one pin groove 64. This is due to the fact that the nut screw 63 is not free to rotate during the counterclockwise rotation of the screw shaft 42.

The tilt arm 68 is pulled by pulling down the tilt arm 68 fixed to one side of the tilt solenoid 61 by the forward movement of the nut screw 63 and the tilt arm 68 is pulled by the tilt arm 68, The tilt bracket 69 fixed together moves downward in association with the movement of the tilt arm 68.

As described above, the tilt bracket 69 is lowered, so that the steering wheel coupled to the tilt bracket 69 also moves downward and is finally tilted down.

At this time, when the nut screw 63 is moved to the rear side by the clockwise rotation of the screw shaft 42, the nut arm 63 is pushed back by pushing the tilt arm 68 fixed to one side to the nut screw 63. The fixed tilt bracket 69 rises up, and this upward movement of the tilt bracket 69 is eventually tilted up by also pushing up the steering wheel coupled thereto.

When the tilt up or tilt down as described above, the teleunit 50 is not operated. As shown in FIG. 6 (b), the teleunit 50 is maintained by the telescrew solenoid 51 so that the nut screw 53 is turned off. Is not constrained.

That is, since the moving pin 52 of the tele solenoid 51 is not fitted into the pin groove 54 due to the off of the tele solenoid 51, the nut screw 53 remains free, and in this state, the screw shaft 42 Even if the clockwise rotation), the nut screw 53 is freely rotated in place without movement, so that the movement of the telerod 58 through the tele solenoid 51 does not occur, and thus the tilt up / down is implemented independently of the tele. It becomes possible.

On the other hand, Figure 7 shows the operation of the teleunit 50 to implement the tele in accordance with this embodiment.

As shown, the operation of the teleunit 50 is driven by the operation state of the electromagnetic clutch 23, the power of the motor 2 is branched to the power connector 20 through the power take-off 30 through the power output unit 40 By being transmitted to, the screw shaft 42 of the power output unit 40 is rotated through this is caused by the bolt screw 42a portion to implement the operation associated with the teleunit 50.

At this time, in order to implement the tele, the tele unit 50 and the tilt unit 60 must be switched to the ready state, respectively.

In this case, Figure 7 (a) is a preparation process for the operation of the teleunit 50, the tele solenoid 51 constituting the teleunit 50 is turned on (On) and at the same time as shown in Figure 7 (b) The tilt unit 60 maintains the tilt solenoid 61 in an off state.

In this state, when the tilt solenoid 61 of the teleunit 50 is turned on, it means that the operation associated with the screw shaft 42 of the power output unit 40 occurs, while the tilt unit 60 By means of maintaining the tilt solenoid 61 of the Off (Off) means that the operation associated with the screw shaft 42 of the power output unit 40 does not occur.

In FIG. 7A, when the tele solenoid 51 of the teleunit 50 is turned on, the operation associated with the screw shaft 42 of the power output unit 40 occurs. In this case, The screw shaft 42 is rotated counterclockwise by the power of the motor 2 transmitted to the output unit 40, and the nut screw 53 coupled to the screw shaft 42 is rotated counterclockwise of the screw shaft 42. It is switched to the state of moving forward to the front (Fig. 7 (a)).

The forward movement of the nut screw 53 as described above is performed such that the moving pin 52 drawn out due to the turning on of the telescopic solenoid 51 is fitted into the one pin groove 54, The nut screw 53 can not be freely rotated when the screw shaft 42 rotates counterclockwise.

Subsequently, the forward movement of the nut screw 53 is transmitted to the telerod 58 having one side fixed to the tele solenoid 51 surrounding the nut screw 53, whereby the telerod 58 is moved forward through the tele solenoid 51. 7 (a) by moving forward, the tele bracket 59 fixed together with the telerod 58 is also moved forward in connection with the movement of the telerod 58.

As described above, the tele bracket 59 moves forward to push the column tube 1, thereby completing a tele action in which a steering wheel coupled thereto moves closer to the driver.

The tilt unit 60 does not operate during the tele action as described above. As shown in FIG. 6 (b), the tilt unit 60 does not restrain the nut screw 63 by keeping the tilt solenoid 61 off. Is caused by.

That is, since the moving pin 62 of the tilt solenoid 61 is not fitted into the pin groove 64 due to the turning off of the tilt solenoid 61, the nut screw 63 remains free, and in this state, the screw shaft 42 ), Even if the clockwise rotation of the nut screw 63 is freely rotated in place without movement, the movement of the tilt arm 68 through the tilt solenoid (61) does not occur, thereby causing the tele to tilt up / down and independently It becomes possible.

The integrated type electric power steering apparatus according to the present embodiment as described above switches the power of the MDPS motor for the assistant assist force to the power for the tilt and the telescopic operation so that one MDPS motor Only one MDPS ECU 70 can be used without a separate tilt / tele-ECU by providing the MDPS ECU 70 with the power switching function of the MDPS motor 2, 23, the power of the MDPS motor 2 is converted into power for tilt up / down and telemetry, thereby reducing costs and increasing weight reduction and packaging.
