Description

Stabilizer bar connector

Technical Field

Exemplary embodiments of the present disclosure relate to a stabilizer bar connector, and more particularly, to a stabilizer bar connector capable of improving connectivity and/or sealability between a socket and a rod (rod).

Background

The stabilizer bar connector is used to suppress relative displacement between the left and right wheels by using the rotational rigidity of the material. That is, the stabilizer bar connector does not work when both wheels are simultaneously moved upward or downward. When the left and right wheels are moved in opposite directions (particularly, the vehicle is rotated), the stabilizer bar connector reduces the relative displacement between the left and right wheels upon torsion, thereby stabilizing the posture of the vehicle and improving the driving force and the rotational force of the vehicle.

The socket and the connector part of the stabilizer bar connector are integrally manufactured by a connection process method, such as forging or die casting. Stabilizer bar connectors having various angles or lengths can be manufactured using techniques for connecting sockets and bars, respectively. However, the strength of the joint portion tends to be lowered as compared with the related art integrated stabilizer bar connecting member.

A problem with the prior art swaging methods for connecting rods and sockets is that it is uncertain whether sufficient strength of the joint can be ensured. In addition, in order to connect the rod and the socket separately, it is necessary to ensure sealability between the rod and the socket. Therefore, it is necessary to solve these problems.

Background of the disclosure the background of the present disclosure is disclosed in korean patent No.10-2398871 (granted under the name of "Stabilizer Link and Method of Manufacturing the Same (stabilizer link and method of manufacturing the same)", 5/12 of 2022.

The rod 100 may be formed in a hollow tube shape. Referring to fig. 1 and 2, sockets 300 may be mounted at opposite ends of rod 100, respectively. The wand 100 may include a wand body 110 and one or more wand protrusions 120.

The rod body 110 may be formed in a hollow tube shape inserted into the socket 300. Sockets 300 may be mounted at two opposite ends of the rod body 110, respectively. The rod body 110 may be formed in a hollow shape so that durability of the rod body 110 may be improved while the weight remains unchanged.

The rod protrusion 120 may protrude annularly from an end outer surface of the rod body 110. The rod protrusion 120 may be coupled to the socket 300 by plastic deformation. When the rod protrusion 120 is pressed by a mechanism such as a swaging machine in a state where the rod protrusion 120 is inserted into the socket 300, the rod protrusion 120 is plastically deformed by the swaging process so that the rod 100 and the socket 300 are integrated.

The rod 100 and socket 300 may be formed into a wave shape by plastic deformation through a swaging process.

The plurality of rod protrusions 120 may protrude from an end outer surface of the rod body 110.
