본 발명은 상부 마운트에 베어링이 구비된 차량 현가장치에 관한 것으로서, 그 베어링이 코일스프링의 지지에 이용되는 차량 현가장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle suspension provided with a bearing on an upper mount, wherein the bearing is used to support a coil spring.

차량 현가장치는, 차량 주행 중에 노면으로부터 전달되는 진동 및 충격 에너지를 흡수하도록 차체와 차축 사이에 제공되어, 차체의 손상을 억제하고, 차량의 승차감을 향상시키는 등의 역할을 한다. 이를 위해, 차량 현가장치는, 노면에서 받는 충격을 완화하는 코일스프링과, 코일스프링의 자유 진동을 억제하여 승차감을 좋게 하는 쇽업소버 등을 포함한다.The vehicle suspension is provided between the vehicle body and the axle so as to absorb vibration and impact energy transmitted from the road surface while the vehicle is running, thereby suppressing damage to the vehicle body and improving ride comfort of the vehicle. To this end, the vehicle suspension apparatus includes a coil spring for mitigating an impact received on a road surface, and a shock absorber for suppressing free vibration of the coil spring to improve ride comfort.

코일스프링과 쇽업소버는 상호 보완 작용을 통해 보다 좋은 승차감을 차량 탑승자에게 제공하다. 보다 구체적으로, 코일스프링은 노면의 굴곡에 의해 차체가 상하로 크게 진동할 때 그 진동으로부터 야기되는 충격을 흡수하고, 쇽업소버는 코일스프링의 진동을 멈추게 하는 저항을 코일스프링에 제공한다.Coil springs and shock absorbers complement each other to provide a better ride to the occupants. More specifically, the coil spring absorbs the shock caused by the vibration when the vehicle body vibrates up and down largely by the bending of the road surface, and the shock absorber provides the coil spring with a resistance to stop the vibration of the coil spring.

통상, 차량 현가장치는 베어링이 설치된 상부 마운트에 별도의 상부 스프링 시트를 설치하고, 그 상부 스프링 시트와 쇽업소버의 실린더에 설치된 하부 스프링 시트가 코일스프링의 양 단부를 지지하도록 되어 있다. 그러나, 상부 마운트에 베어링과 상부 스프링 시트를 별도로 설치하는 것은 차량 현가장치의 조립성을 떨어뜨리며, 상부 스프링 시트의 별도 설치에 따른 많은 비용의 낭비가 뒤따른다.In general, a vehicle suspension device is provided with a separate upper spring seat on an upper mount provided with a bearing, and the upper spring seat and a lower spring seat provided on a cylinder of the shock absorber support both ends of the coil spring. However, separately installing the bearing and the upper spring seat on the upper mount degrades the assemblability of the vehicle suspension, which entails a large waste of cost due to the separate installation of the upper spring seat.

이에 대하여, 종래에는 상부 마운트에 설치된 베어링의 굴곡면에 대략 링형의 고무패드를 끼워, 코일스프링의 일 단부가 그 고무패드에 의해 제공된 시트면에 지지되도록 한 차량 현가장치가 개발된 바 있으며, 이러한 종래의 차량 현가장치는 일본공개특허 제2005-265155호에 개시되어 있다.On the other hand, in the related art, a vehicle suspension device has been developed in which a ring-shaped rubber pad is inserted into a curved surface of a bearing installed in an upper mount so that one end of the coil spring is supported on the seat surface provided by the rubber pad. A conventional vehicle suspension apparatus is disclosed in Japanese Patent Laid-Open No. 2005-265155.

그러나, 종래의 차량 현가장치는, 차량 주행 중 코일스프링의 다양한 거동에 의해, 고무패드가 베어링의 굴곡면으로부터 벗겨지는 문제점이 있었다. 더 나아가, 고무패드는 베어링과 일체성이 없는 이유로, 코일스프링의 횡력에 의해 큰 변형을 일으키는 문제점을 야기한다.However, the conventional vehicle suspension device has a problem in that the rubber pad is peeled off from the curved surface of the bearing due to various behaviors of the coil spring while driving the vehicle. Furthermore, the rubber pad causes a problem of causing large deformation due to the lateral force of the coil spring, for reasons of integrating with the bearing.

본 발명은 베어링의 외부면으로부터 이탈됨 없이 코일스프링의 일단을 지지하는 베어링 상의 패드층을 구비한 차량 현가장치를 제공하는데 그 기술적 과제가 있다.The present invention provides a vehicle suspension having a pad layer on a bearing that supports one end of a coil spring without departing from the outer surface of the bearing.

바람직하게는, 상기 패드층은 접착력 보강을 위한 적어도 하나의 홀이 형성된 베어링 하판에 고무 재질을 코팅하여 이루어진다.Preferably, the pad layer is formed by coating a rubber material on a bearing lower plate having at least one hole for reinforcing adhesion.

본 발명의 다른 측면에 따라, 쇽업서버와 차체를 연결하는 상부 마운트에 설치되며, 상기 쇽업소버에 설치된 스프링 시트와 함께 코일 스프링을 지지하는 차량 현가장치용 베어링이 제공되며, 상기 베어링은 상기 코일스프링과 접하는 외부면에 일체로 코팅된 패드층을 포함하여 이루어진다.According to another aspect of the present invention, there is provided a bearing for a vehicle suspension device which is installed on the upper mount connecting the shock absorber server and the vehicle body, and supports the coil spring with the spring seat installed on the shock absorber, wherein the bearing is the coil spring. It comprises a pad layer coated integrally on the outer surface in contact with.
