Abstract

The invention provides a steering hub system driven by a ball joint universal rotary motor, including a hub body and a connection mechanism. The hub body is connected to a vehicle suspension via the connection mechanism. The hub body includes a ball joint universal rotary motor inside; the ball joint universal rotary motor includes a rotatable spherical shell-shaped rotor body having an opening, a spherical stator body disposed within the rotor body and connected to the connection mechanism, a first coil assembly and a second coil assembly both wound on the spherical stator body; when the first coil assembly is energized, the spherical shell-shaped rotor body rotates with respect to a first axis of the spherical stator body, and when the second coil assembly is energized, the spherical shell-shaped rotor body rotates with respect to a second axis of the spherical stator body, the first axis is not identical to the second axis. A sealing block is disposed at the opening of the spherical shell-shaped rotor body. The motor is a self-starting synchronous servo permanent magnet motor having wide range of stepless speed variation, self-steering power and dustproof ability, and the steering of the motor is sensitive, accurate, smooth, reliable, and convenient for operation, and the steering angle is large.
