Description
Technical Field
The invention belongs to the technical field of automobile parts, and particularly relates to a threaded ratchet steel bushing for mounting a triangular arm ball stud.
Background
The triangular arm is a guide mechanism of an independent suspension automobile, one end of the triangular arm is connected to a frame through a rubber bushing or a joint bearing bushing, and the other end of the triangular arm is connected to a steering knuckle or a wheel reduction gear through a ball pin.
The ball stud is connected to the triangular arm through threads, and in order to increase the thread strength of the ball stud, the designed threads are large in diameter and fine in teeth. Generally, a triangular arm and a ball stud are both steel parts, and the ball stud is directly connected to the triangular arm; because of the need for lighter weight automobiles, many automobiles use aluminum triangular arms to reduce weight. Because the ball stud is made of steel, the strength of aluminum is lower than that of steel, so that the problems that the triangular arm needs to use more expensive special aluminum alloy and a heat treatment mode due to insufficient thread strength, the triangular arm is scrapped integrally due to easy damage of aluminum fine thread of the triangular arm when the ball stud is replaced, the reliability of the connecting thread is reduced (the torque of the connecting thread is reduced or loosened) due to different expansion and contraction degrees of the triangular arm and the ball stud at high and low temperatures due to different materials and the like occur.
In conclusion, the aluminum triangular arm has the defects of high price, easy integral scrapping when the ball pin is replaced, low reliability of threaded connection with the ball pin and the like.

Detailed Description
The technical solutions of the present invention (including the preferred ones) are described in further detail below by means of fig. 1 to 4 and enumerating some alternative embodiments of the present invention. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any inventive step, are within the scope of the present invention.
As shown in figure 1, the threaded ratchet steel sleeve for mounting the triangular arm ball stud comprises a body 2, wherein the body 2 is hollow and columnar, an inner hole of the body 2 is provided with an inner thread 204 connected with the ball stud 3, the outer circle of the inner thread is provided with a guide part 201 connected with the triangular arm 1 and a plurality of strip-shaped protrusions 202, and meanwhile, one end face of the body 2 is provided with a limiting table 203, the outer diameter of which is larger than that of the body, and the limiting table is positioned with the triangular arm 1.
The screw thread ratchet steel bushing adopts the steel material equivalent to ball stud 3, guarantees the intensity that screw thread ratchet steel bushing internal thread 204 and ball stud external screw thread 301 are equivalent (can not lead to the triangle arm to scrap because the screw thread is fragile), and triangle arm 1 then need not select expensive special aluminum alloy material because of the screw thread intensity problem, and both can not cause screw thread ratchet steel bushing 2 and ball stud 3 screw thread to fall to turn round or pine because the inflation is different with the shrink degree when high low temperature environment simultaneously.
Preferably, 0< the radius of the outer wall of the body-the radius of the inner hole of the triangular arm < the height of the strip-shaped bulge.
As shown in fig. 2, 3 and 4, the guide part 201 is in clearance fit with the triangular arm inner hole 101 and plays a role in guiding; body outer wall 202.1 and triangle arm hole 101 interference fit, the protruding 202 of bar simultaneously from triangle arm hole 101 embedding triangle arm 1 body, guaranteed that the moment of torsion that the combination ability of screw thread ratchet steel bushing and triangle arm 1 can bear is big and both can not arouse when high low temperature environment that the pine takes off because of inflation and contraction degree are different.
As shown in fig. 2 and 3, the installation mode of the screw ratchet steel bushing and the triangular arm 1 is that the screw ratchet steel bushing is pressed into the inner hole 101 of the triangular arm, and the process is as follows: the guide part 201 enters, the strip-shaped protrusion 202 enters, and the end face 203.1 of the limiting table is in contact with the first triangular arm end face 102.
As shown in figure 2, the first end surface 205 of the thread ratchet steel bushing is not contacted with the second end surface 103 of the triangular arm.
