Title:
Power steering device
Document Type and Number:
Japanese Patent JP6228929
Kind Code:
B2
Abstract:
A power steering device is provided with a device body and a hollow motor. The device body has a steering system in which a piston is disposed on an output shaft via a ball screw mechanism so that a steering (rotational) torque is transmitted from an input shaft to the output shaft and converted to rotation of a sector shaft by axial movement of the piston for steering of steerable wheels. The hollow motor is connected to the outer circumference of the input shaft and driven by energization control based on driving support information from a vehicle-mounted camera and the like. A key and a key groove are provided on the outer circumference of the input shaft and the inner circumference of a rotor of the hollow motor, respectively, so as to constitute a key connection between the input shaft and the hollow motor.
