본 고안은 자동차용 리어서스펜션에 관한 것으로, 특히 요동각이 최고의치에 도달되었을 때에도 이음이 발생하지 않을 뿐만 아니라 승차감도 향상 시킬 수 있도록 된 자동차용 리어서스펜션에 관한 것이다.The present invention relates to a vehicle suspension, and more particularly, to a vehicle suspension that is capable of improving the riding comfort as well as no noise when the swing angle reaches the highest value.

일반적으로 자동차용 리어셔스펜션은, 불규칙한 도로를 자동차가 주행할 때 발생되는 수직방향의 진동을 감쇄시켜 탑승자에게 안정된 승차감을 제공하도록 설치된 것이다.BACKGROUND ART In general, a rear suspension for a vehicle is installed to provide a stable riding comfort to a passenger by attenuating the vertical vibration generated when the vehicle runs on an irregular road.

종래의 리어서스펜션은 제 3도와 제 4도에 도시된 것과 같이, 차체의 하부에 부착된 브라켓트(11)와, 이 브라켓트(11)에 힌지결합되어 회동가능하게 설치된 아암(12) 및, 이암(12)에 힌지결합됨과 더불어 자체하부의 바디(도시되지않음)에 너트결합된 스트럿조립품(13)으로 이루어져 있다.The conventional suspension has a bracket 11 attached to the lower part of the vehicle body, as shown in FIGS. 3 and 4, an arm 12 hinged to the bracket 11 and rotatably installed, and an arm ( 12) and a strut assembly 13 which is nut-coupled to a body (not shown) of its own lower body.

여기서 상기 스트럿조립품(13)은, 상기 아암(12)과 힌지합된 로드(131a)와 차체하부에 너트결합되는 안충로드(131b)를 갖춘 댐퍼(131)아, 이댐퍼(131)의 완충로드(131b)로 끼워져 상기로드(131a)의 상부에 구비된 타성체지지판(131c)으로 안착되어진 탄성체(132) 및, 이탄성체(132)가 댐퍼(131)에 끼워진 상태로 차체의 하Here, the strut assembly 13 is a damper 131 having a rod 131a hinged to the arm 12 and a nymph rod 131b that is nut-coupled to the lower part of the vehicle body, and a buffer rod of the damper 131. 131b and an elastic body 132 seated on the inertia support plate 131c provided on the upper portion of the rod 131a, and the elastic body 132 is fitted to the damper 131.

부에 배치시킬수 있도록 된 고정수단 (133)으로 이루어져 있다.It consists of a fixing means 133 that can be arranged in the part.

한편 상기 댐퍼(131)의 로드(131A)와 완충로드(131b)의 결합상태는, 상기아암(12)과 힌지연결된 반대쪽이 개방됨과 더불어 기름이 채워진 실린더 형상의 챔버(131d)에 완충로드(131b)가 기워진 상태로 기름이 누출되지 않도록 덮게(131e)가 용접되어 있다.On the other hand, the coupling state of the rod 131A and the buffer rod 131b of the damper 131 is opened on the opposite side hinged to the arm 12, the buffer rod 131b in the oil-filled cylindrical chamber 131d (131e) is welded so that the oil does not leak in the state where) is inclined.

따라서 자동차가 불규칙한 도로를 주행하게 되면 자동차바퀴가 연결되 상기 아암(12)이 브라켓트(11)와 힌지결합된 곳을 기점으로 상승하거나 하강하게 되는 바, 이때 상기 탄성체(132)와 댐퍼(131)에 의해 수직방향의 진동이 감쇄되므로 탑승자의 승차감이 향상되게 된다.Therefore, when the car travels on an irregular road, the wheels of the car are connected, and the arm 12 is raised or lowered from the hinged position of the bracket 11 to the starting point. In this case, the elastic body 132 and the damper 131 are used. The vibration in the vertical direction is attenuated, thereby improving the riding comfort of the occupant.

그러나 이러한 서스펜션구조는, 상기 아암(12)이 회동되어 최고위치로 상승될 때 상기 댐퍼(131)을 구성하는 챔버(131d)의 내벽면과 챔버(131d)를 밀폐시키기 위한 덮게(131e)에서 상기 완충로드(131b)가 차체의 길이방향으로 마찰되므로써 이음(異音)이 발생됨은 물론, 동댐핑계수의 증가로 승차감이 저하되는 결점이 있었다.However, this suspension structure has a cover 131e for sealing the inner wall surface of the chamber 131d constituting the damper 131 and the chamber 131d when the arm 12 is rotated and raised to the highest position. Since the shock absorbing rod 131b is rubbed in the longitudinal direction of the vehicle body, noise is generated and the riding comfort is reduced due to the increase of the dynamic damping coefficient.

이에 본 고안은 상기와 같은 결점을 해결하기 위해 안출된 것으로, 스트럿조립품을 자공내에 부시가 설치딘 아암과 콘트롤링크로 지지하도록 설치함으로써, 댐퍼의 요동각을 최소화하여 마찰력을 감소시켜 승차감을 향상시킴과 더불어 횡강성도 보강할 수 있도록 된 자동차용 리어서스펜션구조를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above drawbacks, and by installing the strut assembly to support the arm with the bushing arm and the control link in the hole, the damping angle of the damper is minimized to reduce the friction force to improve the riding comfort. In addition, the object of the present invention is to provide a suspension structure for automobiles that can reinforce lateral stiffness.

상기와 같은 목적을 달성하기 위한 본 고안은, 차체의 하부에 부착된 브라켓트에 힌지결합되어 회동가능하게 설치된 아암과, 이 아암에 한지결합됨과 더불어 자체하부의 바디에 너트결합된 스트럿조립품으로 이루어진 자동차용 리어서스펜션에 있어서, 상기 스트럿조립품를 이루는 댐퍼의 챔버와 타이어와 소정각도을 이루도록 차체하부에 고정부착된 브라켓트에 콘트롤링크가 힌지결합됨과 더불어, 상기 스트럿조립품의 로드와 챔버에 힌지결합되는 아암과 콘트롤링크에 장공이 형성된 구조로 되어 있다.The present invention for achieving the above object, an automobile hinged to the bracket attached to the lower portion of the vehicle body is installed rotatably, and a strut assembly that is nut-coupled to the body of the lower body and coupled to this arm only In the rear suspension, a control link is hinged to a bracket fixed to a lower portion of a vehicle body to form a predetermined angle with a damper chamber and a tire of the strut assembly, and an arm and a control link hinged to a rod and a chamber of the strut assembly. The long hole is formed in the structure.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안 자동차용 리어서스펜션의 작동상태를 설명하는 개략도이고, 제2도는 콘트롤링크가 설치된 상태를 설명하는 평면도로서, 종래 기술을 설명하는 제3도 및 제4도와 동일한 부위에는 참조부호를 붙이면서 그 설명은 생락한다.FIG. 1 is a schematic diagram illustrating an operating state of a vehicle suspension according to the present invention, and FIG. 2 is a plan view illustrating a state in which a control link is installed. In FIG. The explanation disappears while attaching.

본 고안은, 차체의 하부에 부착된 브라켓트(11)에 힌지결합되어 희동가능하게 설치됨과 더불어 힌지결합된 반대쪽 끝부분에는 장공(12a)이 형성된아암(12)과, 이 아암(12)의 장공(12a)에 힌지결합됨과 더불어 자체하부의바디(도시되지 않음)에 너트결된 스트럿조립품(13)으로 이루어진 자동차용 리어서스펜션에 있어서, 이 스트럿조립품(13)를 이루는 챔버(131d)에 타이어와 예각을 이루도록 차체하부에 고정부착된 브라켓트(2)에 힌지결합된 큰트롤링크(3)의 장공(3a)이 희동가능하게 설치된 구조로 되어 있다.The present invention is hinged to the bracket (11) attached to the lower part of the vehicle body is installed so as to be movable, and the arm (12) having a long hole (12a) formed on the opposite end of the hinge coupled, and the long hole of the arm (12) In a vehicle suspension consisting of a strut assembly 13 hinged to (12a) and nutd to a body (not shown) of its own lower part, the tire and the chamber in the chamber 131d constituting the strut assembly 13. The long hole 3a of the large troll link 3 hinged to the bracket 2 fixedly attached to the lower part of the vehicle body so as to form an acute angle is movable.

여기서 상기 아암(12)의 장공(12a)과 콘트롤링크(3)의 장공(3a)에는, 대략 4각형상의 부시(1)가 끼워져 아암(12)과 콘트롤링크(3)가 차체방향의 진동을 흡수할 수 있도록 희동가능하게 셜치되어 있다.Here, an approximately quadrangular bush 1 is fitted into the long hole 12a of the arm 12 and the long hole 3a of the control link 3 so that the arm 12 and the control link 3 can vibrate in the vehicle body direction. It is cherished so that it can absorb it.

따라서 자동차가 불규칙한 도로를 주행하게 되면 자동차바퀴가 연결된 상기 아암(12)이 브라켓트(11)와 힌지결합된 곳을 기점으로 상승하거나 하강하게 되는 바, 이때 상기 탄성체(132)와 댐퍼(131)에 의해 수직방향의 진동을 감쇄시킴은 물론, 차체방향으로 아암(12)이 희동될 때 발생되는 마찰을 둔각으로 설치된 콘트롤링크(3)가 감쇄시키는 한편, 이 아암(12)과 콘트롤링크(3)에 끼위진 부시(1)에 의해서도 차체방향의 진동을 감쇄시키게 된다.Therefore, when the car travels on an irregular road, the arm 12 connected to the wheel of the car is raised or lowered from the hinged position of the bracket 11 to the starting point. At this time, the elastic body 132 and the damper 131 The control link 3 provided at an obtuse angle reduces friction generated when the arm 12 is moved in the vehicle body direction as well as attenuating the vibration in the vertical direction, while the arm 12 and the control link 3 are attenuated. The bush 1 caught in the shaft also attenuates vibration in the vehicle body direction.

이상 설명한 바와 같이 본 고안에 의하면, 스트럿조립품(13)을 장공(12a)내데 부시(1)가 설치된 아암(12)과 콘트롤링크(3)로 지지할 수 있도록 회동가능하게 설치함으로써,댐퍼(131)의 요동각을 최소화하여 마찰력을 감소시켜 승차감을 향상시킴과 더불어 횡강성도 보강할 수 있는 효과가 있다.As described above, according to the present invention, the strut assembly 13 is rotatably installed to support the arm 12 and the control link 3 provided with the bush 1 in the long hole 12a, thereby providing a damper 131. By minimizing the swing angle of), the frictional force is reduced to improve the riding comfort and reinforce the lateral stiffness.
