Description

차량용 커플드 토션빔 서스펜션의 스프링시트{a spring seat for a coupled torsion beam axle suspension}Spring seat for coupled torsion beam suspension for vehicles {a spring seat for a coupled torsion beam axle suspension}

본 발명은 차량용 커플드 토션빔 액슬 서스펜션의 스프링시트에 관한 것으로, 더 자세하게는 시트본체에 설치되는 스프링패드의 위치를 스프링 조립 전과 스프링 조립 후에 각각 달리하여 스프링 조립이 용이하도록 한 것에 관한 것이다.The present invention relates to a spring seat of a coupled torsion beam axle suspension for a vehicle, and more particularly, to the spring pad to be installed on the seat body to facilitate spring assembly by different positions before and after spring assembly.

도 1에는 일반적인 커플드 토션빔 액슬 서스펜션의 사시도가 도시되어 있다.1 is a perspective view of a typical coupled torsion beam axle suspension.

주로 경차에 사용되는 커플드 토션빔 액슬(CTBA; Coupled Torsion Beam Axle) 서스펜션은 도 1과 같이 토션빔 액슬(40; Torsion Beam Axle)의 양측에 트레일링암(30; Trailing arm)이 장착되고, 트레일링암(30)의 앞쪽에 차체에 장착하기 위한 트레일링암 부시(50)가 설치되며, 트레일링암(30) 후방에 스프링(20) 및 쇽업소버(60) 등을 장착하기 위한 스프링시트(10)와 브라켓이 설치되는 형태를 갖는다.Coupled Torsion Beam Axle (CTBA) suspension, which is mainly used for light cars, is equipped with a trailing arm (30; Trailing arm) on both sides of the Torsion Beam Axle (40) as shown in FIG. A trailing arm bush 50 for mounting to the vehicle body in front of the ring arm 30 is installed, and a spring seat 10 for mounting a spring 20 and a shock absorber 60, etc., behind the trailing arm 30; The bracket is installed.

이처럼 커플드 토션빔 액슬(CTBA) 서스펜션은 후륜 서스펜션을 구성하는 크로스멤버(Torsion Beam & Torsion Bar) 및 암(Trailing arm)을 일체형으로 조립하 는 서스펜션 구조이며, 이러한 토션빔 서스펜션은 단순한 부품으로 인하여 설계 성능 범위가 높지 않음에도 불구하고, 낮은 생산 단가와 낮은 질량에 비해 상대적으로 높은 주행 안정성으로 수십년에 걸쳐서 주로 경차 및 준준형 자동차의 후륜 서스펜션으로 사용되고 있다.As such, the coupled torsion beam axle (CTBA) suspension is a suspension structure that assembles the torsion beam and the torsion bar and the trailing arm that form the rear wheel suspension, and the torsion beam suspension is a simple part. Despite its low design performance range, it has been used as a rear wheel suspension for light and semi-rigid vehicles for decades due to its relatively low production cost and relatively high running stability.

상기 토션빔 서스펜션은 중앙에 위치한 토션빔(beam)의 토션 변형 특성으로 인하여 휠의 변형이 이루어지는 특징이 있으며, 아울러 토션 변형 및 트레일링암의 위치 및 부싱 특성에 의해서 롤(roll)시 언더스티어(understeer)로 유도가 가능한 특징이 있다.The torsion beam suspension is characterized in that the wheel is deformed due to the torsional deformation characteristic of the torsion beam (center) located in the center, and understeer during the roll due to the torsional deformation and the position and bushing characteristics of the trailing arm. ) Can be induced.

한편 종래에 있어서 상기 커플드 토션빔 액슬(CTBA) 서스펜션의 스프링시트는 도 2 내지 도 5와 같이 시트본체(11')에 형성한 체결구멍(11a')에 탄성결합돌기(12a')를 갖는 스프링패드(12')를 탄성 결합한 형태의 것이 주로 사용되었다.Meanwhile, in the related art, the spring seat of the coupled torsion beam axle (CTBA) suspension has an elastic coupling protrusion 12a 'in the fastening hole 11a' formed in the seat body 11 'as shown in FIGS. The spring pad 12 'is mainly used in the form of elastic coupling.

상기 종래의 스프링시트(10')는 비교적 간단한 구조로 용이하게 제작할 수 있게 되지만 스프링패드(12')가 시트본체(11')에 견고하게 고정되어 있기 때문에 스프링(20)을 조립하기가 매우 번거롭게 되는 문제가 있었다.The conventional spring seat 10 'can be easily manufactured with a relatively simple structure, but since the spring pad 12' is firmly fixed to the seat body 11 ', it is very cumbersome to assemble the spring 20. There was a problem.

즉, 도 5에는 종래 스프링시트의 스프링 조립과정도가 도시되어 있는 바, 일반적으로 커플드 토션빔 액슬(CTBA) 서스펜션을 조립할 때에는 트레일링암(30)의 마운팅부(31)를 볼트(32)로 차체에 조립한 다음 쇽업쇼바 및 스프링(20)을 조립하게 된다.That is, Figure 5 is a spring assembly process of the conventional spring seat is shown, in general, when assembling a coupled torsion beam axle (CTBA) suspension, the mounting portion 31 of the trailing arm 30 to the bolt (32) After the assembly to the vehicle body is assembled the shock absorber and the spring (20).

따라서 스프링(20)을 조립할 때에는 트레일링암(30)의 회전 운동으로 인하여 조립 전과 조립 후에 스프링 중심축이 바뀌어야 하지만 종래의 스프링시트(10')와 같이 스프링패드(12')가 시트본체(11')에 고정된 경우 시트본체(11')가 트레일링암(30)에 용접되기 때문에 스프링 중심축이 변하지 않게 되어 스프링(20)의 조립이 매우 번거롭게 되는 문제가 있었다.Therefore, when assembling the spring 20, the spring central axis should be changed before and after assembling due to the rotational movement of the trailing arm 30, but like the conventional spring seat 10 ', the spring pad 12' is the seat body 11 '. When the seat body 11 'is welded to the trailing arm 30, the spring central axis does not change, and thus the assembly of the spring 20 is very troublesome.

본 발명은 상기와 같은 종래의 문제점을 감안하여 안출한 것이며, 그 목적이 트레일링암이 조립된 후 스프링이 설치되는 커플드 토션빔 액슬 서스펜션에 있어서 스프링을 보다 용이하게 조립할 수 있도록 하는 차량용 커플드 토션빔 액슬 서스펜션의 스프링시트를 제공하는 데에 있는 것이다.The present invention has been made in view of the above-mentioned conventional problems, and its purpose is a coupled torsion for a vehicle that makes it easier to assemble the spring in the coupled torsion beam axle suspension where the spring is installed after the trailing arm is assembled. It is to provide a spring seat of the beam axle suspension.

본 발명은 상기의 목적을 달성하기 위하여 시트본체에 형성한 스프링패드 장착구멍의 상부에 스프링패드가 고정 설치되는 작동원판을 상하방향으로 회전 가능하게 설치하여 스프링 조립 전과 스프링 조립 후의 작동원판 및 스프링패드의 위치를 변동시킬 수 있도록 하여서 되는 것이다.In order to achieve the above object, the operation disk and spring pad before and after assembling spring are installed by rotatably installing the operation disk on which the spring pad is fixed and installed in the upper part of the spring pad mounting hole formed in the seat body. It is to be able to change the position of.

아울러 본 발명은 시트본체의 장착구멍 내부 전방과 후방에 각각 지지편을 돌출 설치하여 양 지지편에 작동원판을 힌지 결합하고, 장착구멍의 내부 우측 전방과 후방에 한 쌍의 2절링크를 설치하여 작동원판과 접속하며, 장착구멍의 내부 우측단에 설치한 받침편과 작동원판 사이에 압축스프링을 설치하여 작동원판의 우측 부를 탄성지지하고, 장착구멍의 내부 좌측에 걸림턱을 갖는 회전제한편을 설치하여 작동원판이 수평을 이룰 때까지만 회전되도록 하여서 되는 것이다.In addition, the present invention is installed by protruding the support pieces in the front and rear mounting holes of the seat body, respectively, hinged operation disks on both support pieces, by installing a pair of two-section link in the inner right front and rear of the mounting holes It is connected to the working disk, and a compression spring is installed between the supporting piece installed at the right end of the mounting hole and the working disk to elastically support the right side of the working disk, and to rotate the rotary limiting piece having a locking step at the inner left side of the mounting hole. It is to be rotated only until the working disk is horizontal.

본 발명은 스프링패드 및 장착원판을 시트본체에 상하방향으로 회전 가능하게 설치하여 스프링 조립 전과 스프링 조립 후의 작동원판 및 스프링패드의 위치를 변동시킬 수 있도록 한 것으로, 본 발명에 의하면 스프링 조립 전과 조립 후의 스프링 중심축을 달리하여 스프링의 조립을 용이하게 할 수 있게 됨은 물론 스프링을 안정적으로 지지할 수 있게 되므로 스프링 조립에 소요되는 인력 및 시간, 비용을 크게 절감할 수 있게 되는 등의 효과를 얻을 수 있게 된다.According to the present invention, the spring pad and the mounting disc are rotatably installed in the seat body so that the positions of the working disc and the spring pad before and after the spring assembly can be changed. By changing the spring central axis, the spring can be easily assembled, and the spring can be stably supported, which can greatly reduce the manpower, time, and cost required for spring assembly. .
