Description

Technical Field

[0001] Exemplary embodiments of the present disclosure relate to a stabilizer rod connection, and more particularly, to a stabilizer rod connection capable of improving connectivity and / or sealability between a socket and a rod. Background Art

[0002] The stabilizer bar connector is used to suppress the relative displacement between the left and right wheels by using the rotational stiffness of the material. That is, when both wheels move up or down at the same time, the stabilizer bar connector does not work. When the left and right wheels move in opposite directions (especially when the vehicle turns), the stabilizer bar connector reduces the relative displacement between the left and right wheels when twisting, thereby stabilizing the vehicle posture and improving the vehicle's driving force and rotational force.

[0003] The socket and the connecting member portion of the stabilizer bar connecting member are integrally manufactured by a connecting process method such as forging or die casting. By using the technology of connecting the socket and the rod separately, stabilizer bar connecting members having various angles or lengths can be manufactured. However, compared with the integrated stabilizer bar connecting member in the prior art, the strength of the joint portion tends to be reduced.

[0004] The problem with the swaging method for connecting the rod and the socket in the prior art 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 respectively, it is necessary to ensure the sealability between the rod and the socket. Therefore, it is necessary to solve these problems.

[0005] The background technology of the present disclosure is disclosed in Korean Patent No. 10-2398871 (granted on May 12, 2022, entitled “Stabilizer Link and Method of Manufacturing the Same”). Utility Model Content

[0045] See also Figures 1 to 7 , the stabilizer bar connector according to the first embodiment of the present disclosure may include a rod 100 , an insertion portion 200 , and a socket 300 .

[0046] The rod 100 may be formed in a hollow tube shape. Figure 1 and Figure 2 , the sockets 300 may be respectively installed at two opposite ends of the rod 100. The rod 100 may include a rod body 110 and one or more rod protrusions 120.

[0047] The rod body 110 may be formed in a hollow tube shape inserted into the socket 300. The sockets 300 may be respectively installed at both opposite ends of the rod body 110. The rod body 110 may be formed in a hollow shape so that the durability of the rod body 110 may be improved while the weight remains unchanged.

[0048] The rod protrusion 120 may protrude annularly from the 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 swaging, so that the rod 100 and the socket 300 are integrated.

[0049] The rod 100 and the socket 300 may be formed into a wave shape by plastic deformation through swaging.

[0050] A plurality of rod protrusions 120 may protrude from the end outer surface of the rod body 110. A plurality of rod protrusions 120 may protrude from the end outer surface of the rod body 110 and be arranged at preset intervals. A plurality of rod protrusions 120 may protrude from the end outer surface of the rod body 110 so that a section in which the rod protrusions 120 and the socket 300 are integrated by plastic deformation may be formed to be wide. The rod protrusions 120 and the socket 300 may be plastically deformed so that a firmly coupled state may be maintained.

[0051] The insertion part 200 may be installed in the hollow rod 100. The insertion part 200 may be inserted and installed in the hollow rod body 110. The insertion part 200 may include an insertion body 210 and an insertion stopper 220. The insertion part 200 may be formed in a hollow tube shape.

[0052] The insert body 210 may be installed in the rod 100. The insert body 210 may be formed in a hollow tube shape. The outer diameter of the insert body 210 may be equal to or smaller than the inner diameter of the rod body 110. The insert body 210 may be inserted and installed in the rod body 110.

[0053] The insertion stopper 220 may be formed at an end of the insertion body 210 so as to be larger than an inner diameter of the rod 100. An outer diameter of the insertion stopper 220 may be larger than an inner diameter of the rod body 110.

[0054] The insertion stopper 220 may be formed at an end of the insertion body 210 so as to be larger than an inner diameter of the rod body 110 , so that the insertion stopper 220 may prevent the insertion body 210 from being over-inserted into the rod body 110 .

[0055] The outer diameter of the insertion stopper 220 may be equal to the outer diameter of the rod body 110. The outer diameter of the insertion stopper 220 may be equal to the outer diameter of the rod body 110 so that the insertion stopper 220 may not protrude from the rod 100 inserted into the socket 300.

[0056] The insertion portion 200 may be made of a material having higher strength and hardness than the material of the rod 100. Since the insertion portion 200 is made of a material having higher strength and hardness than the material of the rod 100, when the rod 100 is plastically deformed together with the socket 300 by a swaging machine or the like, excessive deformation of the rod 100 may be prevented.

[0057] In the present disclosure, the insertion part 200 may include a steel material, and the rod 100 may include an aluminum material. The insertion part 200 including a steel material may support the rod 100 to prevent the rod 100 including an aluminum material and plastically deforming with the socket 300 from being excessively deformed.

[0058] The rod 100 may be inserted and installed in the socket 300, and the outer surface of the socket 300 may be coupled to the rod 100 by plastic deformation. The socket 300 may be integrated with the rod 100 by plastic deformation by pressing by a mechanism such as a swaging machine.

[0063] The engaging portion 400 may be applied to a portion of the stick body 110 where the stick protrusion 120 is formed, and the engaging portion 400 may also be applied to the surface of the stick protrusion 120. Alternatively, the engaging portion 400 may be applied to the stick body 110 between a plurality of stick protrusions 120.

[0064] The engagement portion 400 is engaged to the outer surface of the rod 100 and the inner surface of the socket rod 320, so that the rod 100 and the socket 300 can be maintained in a more firmly coupled state.

[0065] The insertion portion 200 may be installed in the rod 100, and the engagement portion 400 may be applied to the outer surface of the rod 100. After the engagement portion 400 is applied to the outer surface of the rod 100, the rod 100 may be inserted and installed in the socket rod 320 of the socket 300.

[0066] The rod 100 and the socket 300 may include the same material. In the present disclosure, the rod 100 and the socket 300 may include an aluminum material. The rod 100 and the socket rod 320 of the socket 300 may include an aluminum material so that the rod 100 and the socket 300 may be integrated by plastic deformation in the same manner through a swaging process pressed by a mechanism such as a swaging machine.

[0067] An assembling process of the stabilizer bar connecting member according to the first embodiment of the present disclosure will be described.

[0068] The insertion part 200 may be inserted and installed in the rod 100. The insertion body 210 may be inserted and installed in the hollow rod body 110. Excessive movement of the insertion body 210 in the rod body 110 may be limited by the insertion stopper 220.

[0069] The engagement portion 400 may be applied to the outer surface of the rod 100. The rod 100 to which the engagement portion 400 is applied may be inserted and mounted within the socket rod 320 of the socket 300.
