ELECTRIC POWER STEERING SYSTEM |
摘要 |
<p>To provide an electric power steering apparatus in which ground processing for respective sections requiring a ground can be reduced to necessary minimum to improve assemblability. An electric power steering apparatus includes a steering column 3 having inserted therein a steering shaft 2 to which steering torque is transmitted and an electric motor 5 that transmits a steering assisting force to the steering shaft 2 via a reduction mechanism in a conductive reduction gear box 4. A control unit 19 including boards 23 and 25 mounted with control circuits that control to drive the electric motor is mounted on the reduction gear box 4, a connecting section of the electric motor 5 is electrically connected to the control unit 19 directly, and connection of the reduction gear box 4 and the control unit 19 to a ground is performed via a grounding line 29 disposed between the control unit 19 and a power feeding unit 30.</p> |
