Title: STEERING HUB SYSTEM DRIVEN BY BALL JOINT UNIVERSAL ROTARY MOTOR
Abstract:
A steering hub system driven by a ball joint universal rotary motor is provided. The steering hub system includes 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 (18) and a second coil assembly (19) 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 (31) is disposed at the opening of the spherical shell-shaped rotor body. The motor is a self-starting synchronous servo permanent magnet motor having a 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.
