Abstract

The present invention relates to an installation structure for an automotive torsion beam spring. A problem of a conventional installation structure for an automotive torsion beam spring is that since both a spring pad bracket and a spring seat are made of steel and coupled by welding, working hours are increased, resulting in poor productivity. The installation structure for an automotive torsion beam spring, which reduces vibrations or shocks during driving by springs (300) installed on trailing arms (200) at both ends of a torsion beam (100), comprises: a spring seat (400) having one end attached to a trailing arm (200), and having a bracket coupling hole (410) provided in the bottom thereof; a spring pad bracket (500) having a spring separation prevention part (510) provided in the center thereof, and having a plurality of engaging hooks (521) provided on the bottom surface of a flange (520) to be caught on the edge surface of the bracket coupling hole (410), being assembled to the spring seat (400); and a spring pad (530) installed on the surface of the spring pad bracket (500) so that a lower end of the spring (300) is placed thereon, thereby reducing vibration noise. The installation structure allows the spring pad bracket (500) to be installed on the spring seat (400) without welding work. Accordingly, working hours can be reduced as the welding work is removed, thereby increasing productivity.

It is to provide a torsion beam spring installation structure for a vehicle that can improve productivity.

일반적으로, 차량은 불균일한 노면을 주행하게 되므로 소음을 수반하는 진동을 받게 되는데, 차체가 흔들리는 현상을 방지하기 위해 스프링과 쇽 업소버 및 스태빌라이저 등의 부재가 설치되고 이러한 부재들은 댐핑력 및 차고 조종의 기능을 주로 행하면서 차량의 승차감과 안정성을 개선하는 역할을 하는데 한다. In general, since a vehicle is traveling on an uneven road surface, it is subjected to vibration accompanied by noise, and members such as springs, shock absorbers, and stabilizers are installed to prevent the vehicle body from shaking. It plays a role in improving the ride comfort and stability of the vehicle while mainly performing a function.

이와 같은 현가장치 중 리어 현가장치는 보통 3개 내지 5개의 링크를 사용하여 액슬의 위치를 결정하는 멀티링크 리어 현가장치를 이루며 현가장치가 지지되는 로워암의 일단은 차륜의 너클이나 캐리어 부위와 부시에 의해 연결되며, 로워암의 타단은 크로스멤버 또는 서브프레임 부위와 부시에 의해 연결된다.Among these suspensions, the rear suspension usually forms a multilink rear suspension that determines the axle position using three to five links. One end of the lower arm on which the suspension is supported is the knuckle of the wheel or the carrier part and the bush. And the other end of the lower arm is connected by a cross member or subframe part and a bush.

여기서, 로워암 및 크로스멤버와 같은 부재를 현가부재라 하며, 소형차에는 로워암 및 크로스멤버 대신에 트레일링암과 토션빔을 포함한 커플드 토션빔 액슬장치가 설치된다.Here, a member such as a lower arm and a cross member is referred to as a suspension member, and a coupled torsion beam axle device including a trailing arm and a torsion beam is installed instead of the lower arm and the cross member in a compact vehicle.

커플드 토션빔 액슬장치는 단순한 부품으로 인하여 설계 성능 영역이 높지 않음에도 불구하고 낮은 생산단가와 작은 질량에 비해 상대적으로 높은 주행 안정성으로 주고 경차 및 준중형차의 후륜 현가장치로 적용돼 왔다.The coupled torsion beam axle system has been applied as a rear-wheel suspension for light vehicles and semi-medium vehicles, giving relatively high driving stability compared to a low production cost and small mass, even though the design performance area is not high due to simple components.

상기 커플드 토션 빔 액슬장치의 선행기술이 대한민국특허청 공개특허 제10-2008-0052078호에 개시되어 있다.The prior art of the coupled torsion beam axle device is disclosed in Korean Patent Application Publication No. 10-2008-0052078.

상기 선행기술에서는 스테빌라이저 바를 토션빔과 트레일링암의 내측으로 배치하여 스트럿 어셈블리의 쇽 업소바와 연결링크를 통하여 연결하여 설치함으로써 토션빔의 과도한 비틀림 토크를 흡수함과 동시에 롤 강성을 높일 수 있도록 하여 그 내구성을 향상시킬 수 있도록 한 것이다.In the prior art, the stabilizer bar is disposed inside the torsion beam and the trailing arm and is connected to the shock absorber of the strut assembly through a connecting link, thereby absorbing excessive torsional torque of the torsion beam and increasing the roll stiffness. It is designed to improve durability.

As the seats can be combined, the time required for welding can be eliminated and the working time can be shortened, thereby improving productivity and having the advantage of high design freedom of the spring pad bracket for automobile torsion. It is to provide a beam spring installation structure.

본 발명의 목적을 달성하기 위해 본 발명은 토션빔 양단의 트레일링암에 스프링을 설치하여 주행 중의 진동이나 충격 발생을 줄여주는 자동차용 토션빔 스프링 설치구조에 있어서, 트레일링암에 일단이 부착되고, 바닥에 브라켓 결합홀이 구비되는 스프링시트; 스프링 이탈방지부가 중앙에 구비되고, 브라켓 결합홀 테두리면에 걸리도록 플랜지 저면에 다수의 걸림후크가 구비되어 스프링시트에 조립되는 스프링패드 브라켓; 스프링의 하단이 놓이도록 스프링패드 브라켓의 표면에 설치되어 진동 소음을 줄여주는 러버재질의 스프링패드로 구성함으로써 상기 목적을 효과적으로 달성할 수 있다.In order to achieve the object of the present invention, the present invention is a torsion beam spring installation structure for automobiles that reduces the occurrence of vibration or shock during driving by installing springs on trailing arms at both ends of the torsion beam, one end is attached to the trailing arm, and A spring seat provided with a bracket coupling hole in the; A spring pad bracket that is provided in the center of the spring separation prevention part and is provided with a plurality of locking hooks on the bottom of the flange so as to be caught on the rim of the bracket coupling hole to be assembled to the spring seat; The above object can be effectively achieved by configuring the spring pad of a rubber material that is installed on the surface of the spring pad bracket so that the lower end of the spring is placed to reduce vibration noise.

이러한 본 발명은 토션빔(100) 양단의 트레일링암(200)에 스프링(300)을 설치하여 주행 중의 진동이나 충격 발생을 줄여주는 자동차용 토션빔 스프링 설치구조에 있어서, 트레일링암(200)에 일단이 부착되고, 바닥에 브라켓 결합홀(410)이 구비되는 스프링시트(400); 스프링 이탈방지부(510)가 중앙에 구비되고, 브라켓 결합홀(410) 테두리면에 걸리도록 플랜지(520) 저면에 다수의 걸림후크(521)가 구비되어 스프링시트(400)에 조립되는 스프링패드 브라켓(500); 스프링(300)의 하단이 놓이도록 스프링패드 브라켓(500)의 표면에 설치되어 진동 소음을 줄여주는 러버재질의 스프링패드(530);로 이루어진 것을 특징으로 한다.In the present invention, in the torsion beam spring installation structure for automobiles to reduce the occurrence of vibration or shock during driving by installing springs 300 on the trailing arms 200 at both ends of the torsion beam 100, the trailing arm 200 has one end. A spring sheet 400 is attached and provided with a bracket coupling hole 410 on the bottom; A spring pad with a spring separation prevention part 510 provided in the center, and a plurality of locking hooks 521 provided on the bottom of the flange 520 so as to be caught on the rim of the bracket coupling hole 410 to be assembled to the spring sheet 400 Bracket 500; It characterized in that it consists of; a rubber material spring pad 530 which is installed on the surface of the spring pad bracket 500 so that the lower end of the spring 300 is placed to reduce vibration noise.

이와 같은 본 발명은 토션빔(100)의 양단에 타이어와 연결된 차체 장착부에 설치되는 트레일링암(200)에 스프링(300)이 설치된 스프링시트(400)를 연결하여 주행 중 차체의 진동이나 충격을 흡수 상쇄시켜 차체에 전달하지 않도록 하여 승차감을 향상시킬 수 있도록 한 것은 일반적인 기술구성이다.The present invention absorbs vibration or shock of the vehicle body while driving by connecting the spring seat 400 with the spring 300 installed to the trailing arm 200 installed on the vehicle body mounting portion connected to the tire at both ends of the torsion beam 100 It is a general technical configuration that offsets and prevents transmission to the vehicle body to improve ride comfort.

그러나 본 발명에서의 특징은 진동이나 충격 흡수를 위한 스프링(300)을 설치하기 위해 스프링패드 브라켓(500)을 스프링시트(400)에 설치 시 용접작업을 하지 않고서도 설치되게 하여 용접작업 삭제에 따른 작업시간을 단축하여 생산성을 향상시킬 수 있도록 한 것이다.However, the feature of the present invention is that when installing the spring pad bracket 500 to the spring sheet 400 to install the spring 300 for absorbing vibration or shock, it is installed without the welding operation. This is to improve productivity by shortening the working time.

즉, 본 발명은 스프링시트(400)와 스프링패드 브라켓(500)을 합성수지재로 형성하되 트레일링암(200)에 일단이 부착되는 스프링시트(400)의 바닥에 브라켓 결합홀(410)을 형성하고, 스프링시트(400)에 결합되는 스프링패드 브라켓(500)의 플랜지(520) 저면에는 걸림후크(521)를 다수 구비하였다.That is, in the present invention, the spring sheet 400 and the spring pad bracket 500 are formed of a synthetic resin material, but the bracket coupling hole 410 is formed at the bottom of the spring sheet 400 to which one end is attached to the trailing arm 200, and , A plurality of locking hooks 521 were provided on the bottom of the flange 520 of the spring pad bracket 500 coupled to the spring sheet 400.

따라서 스프링패드 브라켓(500)을 스프링시트(400)에 결합할 경우에는 우선 스프링패드 브라켓(500)의 플랜지(520)를 브라켓 결합홀(410)에 밀착시키면 플랜지(520)에 형성된 걸림후크(521)가 브라켓 결합홀(410)의 테두리면에 걸리면서 스프링패드 브라켓(500)은 스프링시트(400)에 결합된다.Therefore, in the case of coupling the spring pad bracket 500 to the spring seat 400, first, when the flange 520 of the spring pad bracket 500 is in close contact with the bracket coupling hole 410, the locking hook 521 formed on the flange 520 ) Is caught on the rim of the bracket coupling hole 410, and the spring pad bracket 500 is coupled to the spring sheet 400.

여기서 본 발명은 스프링시트(400)의 브라켓 결합홀(410) 테두리에 다수의 돌기홈(411)을 형성하고, 스프링패드 브라켓(500)의 플랜지(520) 저면에는 회전방지용 돌기(522)를 형성하므로 스프링패드 브라켓(500)을 스프링시트(400)에 결합 시 돌기홈(411)속으로 회전방지용 돌기(522)가 끼워지도록 하면 스프링패드 브라켓(500)은 회전이 방지되어 즉, 스프링시트(400)에 결합된 스프링패드 브라켓(500)은 유동되지 않고 결합된 상태 그대로를 유지한다.Here, the present invention forms a plurality of protrusion grooves 411 on the edge of the bracket coupling hole 410 of the spring sheet 400, and a rotation preventing protrusion 522 on the bottom of the flange 520 of the spring pad bracket 500 Therefore, when the spring pad bracket 500 is coupled to the spring seat 400, if the rotation preventing protrusion 522 is inserted into the protrusion groove 411, the spring pad bracket 500 is prevented from rotating, that is, the spring seat 400 The spring pad bracket 500 coupled to) does not flow and maintains the coupled state.

이후 상단이 범퍼스톱퍼(610)가 형성된 스프링고정부(600)에 고정되게 설치된 스프링(300)의 하단을 스프링패드 브라켓(500)의 바닥에 밀착시켜 주는데 즉, 스프링(300)속으로 스프링패드 브라켓(500)의 스프링 이탈방지부(510)가 끼워지게 하여 스프링(300)이 이탈되는 것을 방지하면서도 상기 스프링(300)의 하단이 안착되는 스프링패드 브라켓(500)바닥에는 러버재질로 이루어진 스프링패드(530)가 설치되어 있어 스프링(300)이 압축되었다가 복원되는 동작을 반복하면서 진동 소음을 흡수 상쇄시킬 때 더욱 더 진동 소음을 효과적으로 상쇄시킬 수 있는 것이다.Thereafter, the lower end of the spring 300 fixedly installed on the spring fixing part 600 on which the bumper stopper 610 is formed is in close contact with the bottom of the spring pad bracket 500, that is, the spring pad bracket into the spring 300 A spring pad made of rubber material on the bottom of the spring pad bracket 500 on which the lower end of the spring 300 is seated while preventing the spring 300 from being separated by fitting the spring detachment preventing part 510 of the 500 Since the 530 is installed, the vibration noise can be more effectively canceled when the spring 300 is compressed and then restored by repeating the operation to absorb and cancel the vibration noise.

이처럼 스프링(300)의 상단은 범퍼스톱퍼(610)가 구비된 스프링고정부(600)에 고정시키고, 하단은 스프링패드 브라켓(500)에 안착되게 한 상태에서 스프링고정부(600)는 종래와 마찬가지로 유동되지 않게 차체에 고정하여 차량이 주행 중 발생되는 진동을 스프링(300)이 흡수 상쇄하여 승차감을 향상시키는 것이다.In this way, the upper end of the spring 300 is fixed to the spring fixing part 600 provided with the bumper stopper 610, and the lower part is mounted on the spring pad bracket 500, and the spring fixing part 600 is similar to the conventional one. It is fixed to the vehicle body so that it does not flow, and the spring 300 absorbs and cancels the vibration generated while the vehicle is running, thereby improving the ride comfort.

그리고 본 발명에서는 스프링패드 브라켓(500)과 스프링 이탈방지부(510)를 모두 플라스틱 재질로 형성하였기 때문에 그만큼 설계자유도가 높아 즉, 차종에 따라 범퍼스톱퍼(610)의 길이가 다를 수 있기 때문에 범퍼스톱퍼(610)가 터치되는 스프링 이탈방지부(510)의 상면(511) 높이를 자유롭게 조절할 수 있는 잇점이 있다.And in the present invention, since both the spring pad bracket 500 and the spring separation prevention part 510 are formed of plastic material, the design freedom is high, that is, the bumper stopper may have different lengths depending on the vehicle model. There is an advantage of being able to freely adjust the height of the upper surface 511 of the spring separation prevention part 510 to which the 610 is touched.

또한, 본 발명에서는 스프링 이탈방지부(510)의 높이를 범퍼스톱퍼(610)가 원활하게 터치될 수 있는 높이로 형성할 때 스프링 이탈방지부(510)의 내면에 보강리브(540)를 다수 형성하여 스프링 이탈방지부(510)의 강성을 증대시켜 장기간에 걸쳐 범퍼스톱퍼(610)가 스프링 이탈방지부(510)의 상면(511)에 터치되더라도 스프링 이탈방지부(510)의 파손됨을 효과적으로 방지할 수 있는 것이다.In addition, in the present invention, a plurality of reinforcing ribs 540 are formed on the inner surface of the spring separation prevention unit 510 when the height of the spring separation prevention unit 510 is formed to a height that the bumper stopper 610 can smoothly touch. Thus, even if the bumper stopper 610 touches the upper surface 511 of the spring separation prevention unit 510 over a long period of time by increasing the rigidity of the spring separation prevention unit 510, it is possible to effectively prevent the damage of the spring separation prevention unit 510. It can be.
