WIPO Patent Application WO/2019/172091
Kind Code:
A1
Abstract:
Provided are a hub unit with a steering function, a steering system, and a vehicle provided with the hub unit with a steering function, with which it is possible to enhance the maneuverability and stability of a vehicle. The hub unit (1) with a steering function is provided with a hub unit main body (2) including a hub bearing supporting a wheel, a unit support member (3) which is provided on an undercarriage frame member of a suspension device, and which supports the hub unit main body (2) with freedom to rotate about a steering axis extending in the vertical direction, and a rolling actuator (5) which rotationally drives the hub unit main body (2) about the steering axis. The hub unit is provided with a steering angle detecting means for detecting the angle of rotation of the hub unit main body (2) about the steering axis. The steering angle detecting means is provided with an angle sensor (Sa) which directly detects the steering angle, a rotation sensor (Sb) which indirectly detects the steering angle from the angle of rotation of a motor (26), and a position sensor (Sc) which indirectly detects the steering angle from the position of a linear motion output unit of a linear motion mechanism.
