Abstract

PURPOSE: A ball joint is provided to avoid the generation of clearance between a ball and a ball seat by improving the ball seat and a supporting structure of the ball seat and compensating as much as the ball seat is abraded. CONSTITUTION: A ball(31) rotates in a state of being supported on an inner face of first and second seat units(50a,50b) so that the rotation and refraction between a ball stud unit(30) and a socket unit(40) are possible. Herein, when the inner curved face of a ball seat(50) is abraded by the action of the ball, the expansion force of an elastic member pushes the first seat unit toward the second seat unit. While the first seat unit moves to the second seat unit, the ball(31) is adhered to the inner face of each seat unit. Thus, even if a ball joint is used for a long time, the clearance between the ball and the inner face of the ball seat is prevented and noises are not generated in its connecting portion.

Rotation and refraction between the portion 30 and the socket portion 40 are possible.

이때, 볼(31)의 동작으로 볼시트(50)의 내곡면이 마모되게 되면, 소켓부(40)의 내면과 제 1시트부(50a)의 이면사이에 설치된 탄성부재(52)의 팽창력에 의해 제 1시트부(50a)가 제 2시트부(50b) 쪽으로 밀어주게 된다.At this time, when the inner curved surface of the ball seat 50 is worn by the operation of the ball 31, the expansion force of the elastic member 52 provided between the inner surface of the socket portion 40 and the rear surface of the first sheet portion 50a. As a result, the first sheet portion 50a is pushed toward the second sheet portion 50b.

즉, 제 1시트부(50a)가 제 2시트부(50b) 쪽으로 이동되면서 볼(31)과 각 시트부(50a,50b)의 내면을 밀착시키게 된다. 따라서, 볼 조인트를 장기간 사용하더라도 볼시트(50a,50b)의 내면과 볼(31)의 유격이 방지되어 이들의 결합부에서 소음 발생이 방지되게 된다.That is, as the first sheet portion 50a is moved toward the second sheet portion 50b, the balls 31 and the inner surfaces of the sheet portions 50a and 50b are brought into close contact with each other. Therefore, even if the ball joint is used for a long time, the clearance between the inner surface of the ball seats (50a, 50b) and the ball 31 is prevented to prevent the occurrence of noise in their coupling portion.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 볼 조인트는 볼의 외면을 감싸 지지하는 볼시트가 소켓부의 내측에 설치되는 제 1시트부와, 소켓부의 입구측에 설치되는 제 2시트부로 구성되며, 제 1시트부와 소켓부의 내측면 사이에는 제 1시트부를 제 2시트부 쪽으로 밀어주는 탄성부재가 설치되었다. 따라서, 볼의 유동으로 각 시트부의 내면이 마모되더라도 탄성부재가 제 1시트부를 밀어주어 볼의 외면과 각 시트부의 내면 사이를 밀착시키게 되므로, 장기간 사용을 하더라도 볼시트의 내곡면과 볼 사이의 유격이 방지되는 이점이 있다.As described above in detail, the ball joint according to the present invention comprises a first seat portion in which a ball sheet covering and supporting the outer surface of the ball is installed inside the socket portion, and a second seat portion installed in the inlet side of the socket portion, An elastic member is provided between the first sheet portion and the inner surface of the socket portion to push the first sheet portion toward the second sheet portion. Therefore, even if the inner surface of each sheet portion is worn out due to the flow of the ball, the elastic member pushes the first sheet portion to closely adhere between the outer surface of the ball and the inner surface of each sheet portion. This has the advantage of being prevented.
