차량용 레이디어스 로드유닛 {RADIUS ROD UNIT FOR VEHICLE}Radius Road Unit for Vehicles {RADIUS ROD UNIT FOR VEHICLE}

본 발명의 예시적인 실시예는 차량용 레이디어스 로드유닛에 관한 것으로서, 보다 상세하게는 리어 서스펜션에 적용되는 차량용 레이디어스 로드유닛에 관한 것이다.An exemplary embodiment of the present invention relates to a vehicle radial load unit, and more particularly, to a vehicle radial load unit applied to a rear suspension.

일반적으로, 차량의 리어 서스펜션장치는 주행시 노면에서 받는 충격을 완화하여 승차감을 좋게 하기 위한 것이다.In general, the rear suspension device of a vehicle is to alleviate the shock received from the road surface while driving to improve the riding comfort.

이러한 리어 서스펜션 장치는 스프링과, 스프링의 고유 진동을 흡수하는 쇽 업쇼바와, 좌우로 흔들리는 것을 방지하는 스테이빌라이저와, 차체와 액슬을 연결하여 차량의 선회 또는 제동 시에 발생되는 힘을 지지하기 위한 레이디어스 로드유닛으로 구성된다.The rear suspension device includes a spring, a shock absorber that absorbs the natural vibration of the spring, a stabilizer that prevents the swing from side to side, and a body and axle to support the force generated when the vehicle is turned or braked. It is composed of a radial load unit.

이 중에서 상기 레이디어스 로드유닛은 도 2에서와 같이, 장착 브라켓(미도시)을 통하여 일측 단부가 차체에 연결되고, 다른 일측 단부가 액슬에 연결되는 레이디어스 로드(120)를 구비하고 있다.Among these, the radial load unit is provided with a radial rod 120 having one end connected to the vehicle body and the other end connected to the axle through a mounting bracket (not shown) as shown in FIG. 2.

상기 레이디어스 로드(120)의 양측 엔드부(121)에는 원통 형상의 장착홀(123)이 구비되고, 그 장착홀(123)에는 마운트 볼트(미도시)를 통해 장착 브라켓 과 체결되는 금속 소재의 핀부(130)가 삽입된다.Both end portions 121 of the radial rod 120 are provided with mounting holes 123 having a cylindrical shape, and the mounting holes 123 are formed of a metallic material which is fastened with a mounting bracket through a mounting bolt (not shown). The pin 130 is inserted.

그리고, 상기 핀부(130)의 외주면과 장착홀(123)의 내주면 사이에는 부시 고무(140)가 개재된다.In addition, the bush rubber 140 is interposed between the outer circumferential surface of the pin 130 and the inner circumferential surface of the mounting hole 123.

따라서 상기 레이디어스 로드유닛은 차량의 브레이킹 및 가속 시에 발생하는 힘으로부터 액슬의 정렬각을 유지하고, 차량의 전후 방향에 대한 힘을 지지하게 된다.Therefore, the radial load unit maintains the alignment angle of the axle from the force generated during braking and acceleration of the vehicle, and supports the force in the front-rear direction of the vehicle.

그런데, 종래 기술에 따른 레이디어스 로드유닛은 양산 차량에서 변속기 및 액슬로부터 전달되는 진동에 의해 국부적인 떨림이 발생하는 등 차량의 NVH 성능을 저하시킨다는 문제점을 내포하고 있다.By the way, the prior art radial load unit has a problem in that the NVH performance of the vehicle is degraded, such as a local vibration occurs by the vibration transmitted from the transmission and the axle in a mass production vehicle.

본 발명의 예시적인 실시예는 상기에서와 같은 문제점을 개선하기 위하여 창출된 것으로, 핀부와 장착 브라켓을 체결하기 위한 마운트 볼트의 강도에 직접적인 영향을 미치지 않으면서 변속기 및 액슬로부터 전달되는 진동 및 소음을 저감시킬 수 있도록 하는 차량용 레이디어스 로드유닛을 제공하는데 그 목적이 있다.Exemplary embodiments of the present invention have been created to remedy the above-mentioned problems, and provide vibration and noise transmitted from the transmission and the axle without directly affecting the strength of the mount bolt for fastening the pin and the mounting bracket.

To support the generated force, a circular mounting hole is provided at both end portions of the radial rod, a pin portion coupled to the mounting bracket is inserted into the mounting hole, and an outer circumferential surface of the pin portion and an inner circumferential surface of the mounting hole are provided. Bush rubber is interposed between, characterized in that the mass damper is mounted to at least one end of the pin portion.

상기 차량용 레이디어스 로드유닛에 있어서, 상기 매스 댐퍼는 금속 소재로서 이루어지며, 볼트를 통해 상기 핀부의 적어도 일측 단부에 체결될 수 있다.In the vehicle radial load unit, the mass damper is made of a metal material, and may be fastened to at least one end of the pin portion through a bolt.

상기 차량용 레이디어스 로드유닛에 있어서, 상기 매스 댐퍼는 상기 핀부에 체결되는 체결부와, 상기 체결부와 일체로 형성되며 그 체결부 보다 상대적으로 두껍게 형성되는 매스부로 이루어질 수 있다.The mass damper may include a fastening part fastened to the pin part and a mass part integrally formed with the fastening part and formed relatively thicker than the fastening part.

상술한 바와 같은 본 발명의 예시적인 실시예에 의하면, 핀부의 단부에 매스 댐퍼를 장착함으로, 변속기 및 액슬로부터 전달되는 진동 및 소음을 저감시켜 차량의 NVH 성능을 향상시킬 수 있다.According to the exemplary embodiment of the present invention as described above, by mounting the mass damper at the end of the fin portion, it is possible to reduce the vibration and noise transmitted from the transmission and the axle to improve the NVH performance of the vehicle.

또한, 본 실시예에서는 매스 댐퍼가 마운트 볼트를 통한 핀부와 장착 브라켓의 체결 부위에 직접적으로 장착되지 않고 그 핀부에 별개로서 장착되는 바, 마운트 볼트의 강도에 영향을 미치지 않게 함으로써 마운트 볼트의 토크 저하를 방지할 수 있으며, 안정성을 확보할 수 있다.In addition, in this embodiment, the mass damper is not directly mounted to the fastening portion of the pin portion and the mounting bracket through the mount bolt, but is mounted separately from the pin portion, so that the torque of the mount bolt is lowered by not affecting the strength of the mount bolt. Can be prevented and stability can be ensured.

그리고, 본 실시예에서는 매스 댐퍼가 마운트 볼트와는 별도로 핀부에 장착 볼트를 통하여 체결되므로, 그 매스 댐퍼를 손쉽게 교환 장착하는 등 조립성 및 A/S가 용이하다.In addition, in this embodiment, since the mass damper is fastened to the pin part separately from the mounting bolt, the mass damper is easily assembled and replaced, such as easily replacing the mass damper.
