Description
본 발명은 차량용 조향장치의 회전력을 전달하면서 축을 연결시키기 위한 인너볼 조인트에 있어서, 상기 인너볼 조인트의 조립을 간편하게 하면서 상기 조인트의 간극(유격)을 적정하게 조절하여 유지할 수 있도록 하고 볼조인트의 조립을 토오크를 조절하면서 조립가능한 조절볼트로 체결시켜 결합하도록 하므로써 회전강성을 조절할 수 있도록 하고 상기 조인트의 유동을 방지할 수 있도록 한 차량용 조향장치의 인너볼 조인트에 관한 것이다.In the inner ball joint for connecting the shaft while transmitting the rotational force of the steering device for the vehicle, the inner ball joint can be easily adjusted while maintaining the clearance (gap) of the joint appropriately and the assembly of the ball joint The present invention relates to an inner ball joint of a steering device for a vehicle capable of controlling rotational rigidity and preventing a flow of the joint by fastening and coupling with an adjustable bolt that can be assembled while adjusting torque.
일반적으로 차량용 조향장치에는 인너볼 조인트가 사용되며, 이러한 종래의 인너볼 조인트는 도 1에서 보는 바와 같다.In general, an inner ball joint is used for a vehicle steering apparatus, and the conventional inner ball joint is as shown in FIG. 1.
즉, 볼하우징(2)이 선단에 형성된 구동축(1)에 볼조인트(4)가 선단에 형성된 종동축(3)을 결합시키되, 상기 볼조인트(4)에 볼시트(5)를 씌워 설치하고 이 볼시트(5)가 설치된 상기 종동축(3)의 볼조인트(4)를 상기 구동축(1)의 볼하우징(2)에 삽입시킨 다음. 이 볼하우징(2)의 양단을 프레스로 눌러 상기 볼하우징과 볼조인트가 결합되도록 하며 이들의 결합에 따라 상기 구동축의 회전력이 종동축으로 전달되도록 구성되어 있었다.That is, while the ball shaft (4) is coupled to the drive shaft (1) formed at the tip of the ball joint (4) driven shaft (3) formed at the tip, the ball joint (4) is installed by covering the ball seat (5) The ball joint (4) of the driven shaft (3) provided with the ball seat (5) is inserted into the ball housing (2) of the drive shaft (1). Pressing both ends of the ball housing (2) by the press to the ball housing and the ball joint is configured to be coupled so that the rotational force of the drive shaft is transmitted to the driven shaft according to their combination.
그러나, 상기와 같은 종래의 것은 상기 볼조인트를 설치하기 위하여 상기 볼하우징을 프레스로 눌러 결합하도록 구성되어 있었기 때문에 상기 프레스 가공시의 압력에 따라 상기 볼조인트의 결합상태가 불량하게 되는 폐단이 있었으며, 또, 상기 볼조인트와 볼시트 및 볼하우징 사이에 이들의 회동을 위한 적정한 간극을 형성하게 되는데, 상기 프레스작업에 의한 결합으로 상기 간극을 일정하고 적정하게 맞추기 어렵게 되는 결점이 있었고 이에 따라 상기 볼조인트의 회전강성이 약화되고 마모율이 높게되면서 소음이 발생되어 조향력을 저하시키는 점 등의 문제점이 있었다.However, since the conventional one is configured to press the ball housing by pressing to install the ball joint, there is a closed end in which the state of engagement of the ball joint becomes poor according to the pressure during the press working. In addition, an appropriate gap is formed between the ball joint, the ball seat, and the ball housing for the rotation thereof, and there is a defect in that it is difficult to uniformly and properly adjust the gap by the combination of the press work. The rotational rigidity of the weakened and the wear rate was high, there was a problem such as noise is generated to reduce the steering force.
본 발명은 상기와 같은 종래의 문제점을 개선하기 위해 안출한 것으로 본 발명은 차량용 조향장치의 회전력을 전달하면서 축을 연결시키기 위한 인너볼 조인트에 있어서, 상기 인너볼 조인트의 조립을 간편하게 하면서 상기 조인트의 간극(유격)을 적정하게 조절하여 유지할 수 있도록 하고 볼조인트의 조립을 토오크를 조절하면서 조립가능한 조절볼트로 체결시켜 결합하도록 하므로써 회전강성을 조절할 수 있도록 하고 상기 조인트의 유동을 방지할 수 있도록 한 차량용 조향장치의 인너볼 조인트를 제공하려는 것인바, 이를 이하에서 첨부한 도면과 실시예에 의거 상세히 설명하면 다음과 같다.The present invention has been made in order to improve the conventional problems as described above, the present invention in the inner ball joint for connecting the shaft while transmitting the rotational force of the steering device for the vehicle, the assembly of the inner ball joint while simplifying the assembly gap Vehicle steering to adjust and maintain the (gap) properly and to adjust the rotational stiffness by fastening the assembly of the ball joint with the adjustable bolt that can be assembled while adjusting the torque, and to prevent the flow of the joint It is intended to provide an inner ball joint of the device, which will be described in detail with reference to the accompanying drawings and examples below.
