Single-axis damping joint for connecting chassis components for vehicles

摘要

The present invention relates to a single-axis damping joint for connecting chassis components for a vehicle, and more particularly, to a single-axis damping joint for connecting chassis components for a vehicle, capable of improving performance of absorbing forward and backward vibration of a vehicle body and vibration due to distortion force while improving durability.;To this end, the present invention provides the single-axis damping joint for connecting chassis components for the vehicle, including: a ball stud including a spherical portion on an axis; bearings disposed so as to induce rotation of the ball stud in an axis direction; a sheet member configured to support an external circumferential surface of the bearing; a buffer member disposed at an external circumferential surface of the sheet member; and an outer pipe configured to protect the sheet member from the outside while being in close contact with the external circumferential surface of the sheet member and coupled to one end of a lower arm.

1. A single-axis damping joint for connecting chassis components for a vehicle, comprising:
a ball stud including a spherical portion on an axis; bearings disposed so as to induce rotation of the ball stud in an axis direction; a sheet member configured to support an external circumferential surface of the bearings; a buffer member disposed at an external circumferential surface of the sheet member; ring-shaped sealing members configured to prevent foreign substances and water from passing through from the environment outside of the damping joint disposed at both outer ends of the bearings in the axis direction so as to compress an external circumferential surface of the ball stud; and an outer pipe configured to protect the sheet member from the environment outside of the damping joint while being in close contact with the external circumferential surface of the sheet member and coupled to one end of a lower arm, wherein the sheet member has a space spaced by a predetermined distance formed between the buffer member, the bearings, and the sealing members, and is formed by filling the space with plastic by insert molding.
