  In the harness used for the power line and signal line between the motor in the in-wheel motor drive device and the inverter of this motor, especially in the front wheel with steering, in the linear motion that is the vertical motion in the suspension and in the steering A combined force of rotational motion is applied, and durability testing requires a corresponding method. Patent document 3 is an example of the wiring of the power line between the motor and inverter in an in-wheel motor drive device.

Patent Document 1 is an apparatus that performs a durability test by bending a test harness that simulates a vehicle door.
Patent Document 2 is an apparatus that performs a durability test by linearly bending a harness. This device cannot be applied to a harness used for an in-wheel motor drive device because the bending characteristics thereof are different from those of the in-wheel motor drive device attached to the vehicle body.

FIG. 5 shows an example of a right front wheel in which the in-wheel motor drive device 3 is attached to the vehicle body 4.
A structure in which the wheel 2 and the tire 1 are attached to the in-wheel motor driving device 3 is attached to the vehicle body 4 using the upper arm 5 and the lower arm 6. In FIG. 5, the suspension is not shown for simplification.

Depending on the road surface condition, the tire 1 generates a vertical stroke with respect to the vehicle body 4. In this case, linear motion force is transmitted in the vertical direction from the terminal box 8 attached to the in-wheel motor drive device 3 to the high voltage harness 10 wired to the wiring inlet 9 on the vehicle body 4 side.
In this case, the high voltage harness 10 takes the extended state of FIG. 6A and the contracted state of FIG. 6C from the neutral state of FIG.

  Moreover, as shown in FIG. 5, the rotational force of the handle (not shown) is transmitted to the in-wheel motor drive device 3 via the tie rod 7, and the wheels can be steered. In this case, the terminal box 8 to which the high voltage harness 10 is connected generates a rotational motion, and the high voltage harness 10 also transmits the turning force.

FIG. 7 is a plan view of the state of the high voltage harness 10 and the like when the wheels are steered, as viewed from above. When the wheels are steered, the terminal box 8 (FIG. 5) turns about the steered shaft (kingpin) 11 to positions 8A to 8B and 8C. In this case, the high voltage harness 10 also receives a pulling force due to the turning force.
Accordingly, the high-voltage harness 10 wired to the movable terminal box 8 receives the force that moves in the up and down direction and the force that rotates in the turning direction from the wiring drawing port 9 on the fixed side.

The “vertical direction” around the vertical axis and the “vertical direction” for reciprocating in the vertical direction are not limited to the vertical direction, and may be appropriately changed according to the test conditions of the vehicle. .

  According to this configuration, the test harness is disposed between the vehicle body side harness fixing portion and the in-wheel side harness fixing portion. The swing mechanism swings the in-wheel side harness fixing portion around the vertical axis relative to the vehicle body side harness fixing portion. At the same time, the linear motion mechanism reciprocates the in-wheel side harness fixing portion in the vertical direction relative to the vehicle body side harness fixing portion.

  In this case, the oscillating body is oscillatingly driven by the oscillating drive source, and the linear motion part is reciprocated along the linear motion guide unit by the linear motion drive source of the linear motion table. A harness bending test device for an in-wheel motor drive device can be realized by combining such a linear motion table and a swing mechanism.

  The oscillating mechanism includes a linear motion portion provided on the fixed portion so as to be capable of linear motion, and a conversion mechanism that converts the linear motion of the linear motion portion into the oscillating motion of the rocking body. May be. For example, a link mechanism can be applied as the conversion mechanism. Thus, the swing motion of the swing body can be substituted by combining the linear motion of the linear motion portion and the conversion mechanism.

Settings can be changed. Further, the controller 21 can change settings such as whether the oscillating body 30 and the linear motion unit 15 are synchronized or randomly operated by an operator input. By changing various settings, the movement in the actual vehicle can be simulated by combining the stroke motion (vertical motion) in the vertical direction L2 and the rotational motion (steering motion) in the steering direction A1.

One end portion of the link member 18 in the longitudinal direction is connected to a support shaft 20 that is swingably supported by the support 24. The support shaft 20 can swing around a vertical axis.

  When the oscillating drive source 31 is driven and the linear motion portion 16 is linearly moved, the pin 17 applies a force in the moving direction of the linear motion portion 16 to the long hole 18a of the link member 18, whereby the link member 18 is moved. Swings about the support shaft 20. At the same time, the linear motion mechanism unit 26 reciprocates the linear motion unit 15 in the vertical direction L2 with respect to the in-wheel harness fixing unit 27.
