TRANSMISSION-TYPE POWER STEERING DEVICE

摘要

A transmission-type power steering device comprises: a motor; a worm shaft provided with a worm gear, and connected to an output axis to integratingly rotate with the output axis of the motor; a worm wheel coupled to a steering shaft, and autogerous-welded on the worm gear; a support bearing placed on the close side to the motor with the worm gear of the worm shaft as the center, so as to be coupled to the worm shaft; a tilt bearing assembly placed on the far side from the motor with the worm gear of the worm shaft as the center, so as to be coupled to the worm shaft; and a tilting mechanism applying strength to the tilt bearing assembly so that the worm shaft can be tilted in the direction of being pushed towards the worm wheel.
