Abstract
The utility model aims at providing a can prevent effectively that the loose spacious, the abnormal sound of arm support axial that hangs down from turning to the axial anti loosening structure of arm support that hangs down, including the support body, be provided with in the support body inner chamber and be used for the pivot with the installation muffjoint of the arm that hangs down, the port department of support body is provided with the plug screw, and the external screw thread of plug screw constitutes threaded connection with the tip of support body, and the plug screw is seted up porosely along the axial with the tip juncture of support body, and the round pin axle impresses downthehole and constitutes interference fit. The arm support axial clearance that hangs down mainly guarantees by the position of plug screw, consequently punches and adds the pintle and constitute interference fit between plug screw and support body, prevents the not hard up trouble of plug screw after long-time the use, has improved the reliability and the life of the arm support that hangs down to a great extent.
Description
Technical Field
The utility model relates to a car a steering system technical field, concretely relates to car turns to axial anti loosening structure of arm support that hangs down.
Background
The automobile steering vertical arm is an important part for connecting an automobile steering device and a steering pull rod, and the vertical arm support supports the vertical arm through the connection of a rotating shaft and a sleeve arranged on the steering vertical arm, so that the performance of the vertical arm support directly influences the operation comfort and safety of a driver.
At present, a vertical arm support in an automobile steering system (using a recirculating ball steering engine) is axially and generally in a simple structure by directly pressing after a threaded sleeve is connected with a support body by threads or coating thread locking glue on the threads. But directly with threaded connection, the screw thread will become flexible after long-time use, leads to the axial clearance too big, appears that the steering system is loose, the abnormal sound scheduling problem. If the thread locking glue is coated on the threads, the rotating moment of the support rotating shaft is not easy to adjust during assembly.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can prevent effectively that the loose spacious, the abnormal sound of plumbing arm support axial from the axial anti loosening structure of auto steering plumbing arm support.
In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides an axial anti loosening structure of auto steering arm support that hangs down, includes the support body, is provided with the pivot that is used for with the installation muffjoint of the arm that hangs down in the support body inner chamber, and the port department of support body is provided with the plug screw, and the external screw thread of plug screw constitutes threaded connection with the tip of support body, and the plug screw is seted up porosely along the axial with the tip juncture of support body, and the round pin axle impresses downthehole and constitutes interference fit.
The arm support axial clearance that hangs down mainly guarantees by the position of plug screw, consequently punches and adds the pintle and constitute interference fit between plug screw and support body, prevents the not hard up trouble of plug screw after long-time the use, has improved the reliability and the life of the arm support that hangs down to a great extent.

Fig. 1 is a sectional view of the present invention.
Detailed Description
As shown in fig. 1, an axial anti-loosening structure of an automobile steering plumbing arm support comprises a support body 10, a rotating shaft 20 connected with a mounting sleeve of a plumbing arm is arranged in an inner cavity of the support body 10, a plug screw 30 is arranged at a port of the support body 10, an external thread of the plug screw 30 is in threaded connection with an end of the support body 10, a hole is formed in a junction of the plug screw 30 and the end of the support body 10 along the axial direction, and a pin shaft 40 is pressed into the hole and forms interference fit. The support body 10 is connected with the mounting sleeve of the vertical arm through the rotating shaft 20, and the axial clearance of the rotating shaft 20 is mainly ensured by the position of the screw plug 30, so that the screw plug 30 is particularly important to be reliably connected with the support body 10, then the pin shaft 40 and the hole are in interference fit, and the pin shaft 40 firmly fixes the screw plug 30 and the support body 10 together, so that the screw plug 30 cannot be loosened due to long-time use of the support body 10, and meanwhile, the contradiction that the tightening torque of the screw plug 30 of the support body 10 and the rotating torque of the rotating shaft cannot be balanced is solved.
In order to improve the connection reliability, a plurality of holes are provided at intervals in the circumferential direction of the plug screw 30, and a plurality of pin shafts 40 are provided correspondingly.
Further, a spring seat 51 is provided between the rotating shaft 20 and the screw plug 30, a disc spring 52 is provided on the spring seat 51, and the disc spring 52 abuts against the end surface of the screw plug 30.
In order to prevent the entry of foreign materials, the end of the stand body 10 is also covered with a dust cover 60.
The installation steps are as follows: after the shaft 20 is installed in the socket body 10 filled with the lithium grease, the spring seat 51 and the belleville spring 52 are sequentially installed, and then the screw plug 30 is screwed into the socket body 10. After the above processes are completed, the rotating torque and the axial clearance of the rotating shaft are detected, and the rotating torque and the axial clearance of the rotating shaft are adjusted by the screwing tightness of the screw plug 30. When the rotating torque and the axial clearance of the vertical arm support rotating shaft meet the design requirements, the screw plug 30 and the support body 10 are axially perforated at the threaded joint part, and then the pin shaft 40 is pressed into the hole.
