Abstract
The invention relates to a steering control device of a motor reducer worm shaft, which comprises a box body and a rotating shaft positioned in the box body. A one-way clutch is installed on the rotating shaft and fixed in a bearing sleeve which is installed inside the box body and forms a state of clearance fit with the box body; a notch or a bump is arranged at the outer edge of the bearing sleeve, and a stop pin which can be pressed in and popped out is arranged on the box body corresponding to the notch or the bump; when being pressed into the box body, the stop pin is integrally positioned in the box body, and simultaneously the one-way clutch positioned inside the bearing sleeve does not play a role on the rotating shaft, thus realizing the out of control of bi-directional rotation of the rotating shaft; when the stop pin is popped out, the outer part of the stop pin protrudes out of the box body and limits the rotation of the bearing sleeve, therefore, the one-way clutch controls the rotating shaft, and the rotating shaft only rotates in a one-way way according to the steering controlled by the one-way clutch; and optimally, the stop pin is designed as a spring switch, wherein a spring is arranged in the hole for installing the stop pin in the box body so as to control the stop pin to be pressed into and popped out of the hole of the stop pin.
