The invention discloses an omni-directional steering wheel-side steering suspension mechanism. A wheel-side steering mechanism and a suspension system which are suitable for a hub motor driving automobile and can achieve omni-directional steering are included. The wheel-side steering mechanism is composed of a steering knuckle, a steering motor, a worm gear and worm set and a rotating angle position sensor. The suspension system comprises an upper transverse arm, a lower transverse arm and a spring shock absorber. The steering knuckle is composed of a steering knuckle shaft and a steering knuckle shell. The outer end of the upper transverse arm is connected with the steering knuckle shell. The lower transverse arm and the steering knuckle shaft are hinged. The steering knuckle shaft is mounted on a hub motor stator shaft through a center hole in the steering knuckle shaft. A worm gear is mounted on the steering knuckle shaft. The steering knuckle shell is mounted on the steering knuckle shaft in a sleeving mode. The steering motor is fixed to the steering knuckle shell. The output end of the steering motor is a worm. The worm gear and the worm are engaged in the steering knuckle shell. During steering, the steering motor drives a worm gear and worm mechanism, the steering knuckle shaft is made to rotate in the steering knuckle shell, and a wheel is made to reach the target rotating angle.
