The invention discloses a thread locking structure of a vehicle steering device inner ball. The thread locking structure comprises a thread, a support, a dustproof cover, a steering shaft, a fixed plate, an adjusting nut, a steering rack, a stop piece, a stop cover, a sleeve, a flange and a locking device. The thread is embedded and installed in the outer surface of the support. The support is connected with the bottom face of the dustproof cover. The thread locking structure comprises the locking device which is embedded and installed on the side face of the steering rack, a clamping toothedhead on a gear in the locking device and a rack body on the steering rack are buckled, then a spring bears downward pressure of force when a rotating rod operates and is shortened, when the rotating rod goes down due to shaking, the spring can be shortened to a certain extend and then rebound upward, the supporting plate moves upward, the rotating rod also moves upward to be buckled together withthe steering rack, it is avoided that the loosening phenomenon is caused by long-time rotating, and the thread locking structure is more convenient and practical to use.
Description
technical field [0001] The invention relates to an anti-loosening structure of an inner ball thread of an automobile steering gear, and belongs to the field of an anti-loosening structure of an inner ball thread of a steering gear. Background technique [0002] The function of the steering gear is to properly transform the steering torque and steering angle from the steering wheel, and then output it to the steering rod mechanism to make the car turn. Therefore, the steering gear is essentially a reduction transmission device, generally with 1 to 2 stages of reduction transmission Vice, steering gear has many types, such as rack and pinion type, recirculating ball type, worm crank finger type, power steering gear and so on. [0003] The prior art discloses an anti-loosening washer with an application number of 201620816061.X and an anti-loosening structure of an inner ball thread of an automobile steering gear, wherein the anti-loosening washer includes a body of the anti-lo...
