INTEGRAL-TYPE ELECTRIC POWER STEERING DEVICE

摘要

An integral-type electric power steering device is configured in such a way that a motor component (40), a reduction mechanism (20), and a control device (50) are integrally fixed, and the control device (50) includes at least heating elements (531) having the control-circuit elements, which are operated so as to generate heat, a control board (53) on which the heating elements (531) are mounted, and a mechanism components (500) for fixing the control board (50); and at least a part of the heat, which is generated by the heating elements (531), is conducted to the mechanism components (500) via a thermal-conductive component (57).

1. An integral-type electric power steering device comprising:
a motor component including a motor that generates an assist torque corresponding to a steering torque caused by a driver in a car and applies the generated assist torque to a steering shaft of the car via a reduction mechanism; and a control device including control-circuit elements for controlling the motor in a state where the motor component, the reduction mechanism, and the control device are integrally fixed; wherein the control device includes at least heating elements having the control-circuit elements, which are operated so as to generate heat, a control board on which the heating elements are mounted, and a mechanism components for fixing the control board; and at least a part of the heat, which is generated by the heating elements, is conducted to the mechanism components via a thermal-conductive component.
