Abstract

PURPOSE: A semi multipoint support rear wheel torsion beam suspension is provided to improve riding comfort without changing a structure by reducing and absorbing shock and vibration. CONSTITUTION: A semi multipoint support rear wheel torsion beam suspension has a damper(2) to a middle portion of a torsion beam(1). An upper end of the damper is connected to a lower portion of a vehicle body and a lower end of the damper is installed to the middle portion of the torsion beam. A stopper, a combination of the stopper and a weight are used instead of the damper. Thereby, shock and vibration are reduced and absorbed by a damping member installed to the middle portion of the torsion beam.

Description

세미 다점 지지 후륜 토션 빔 서스펜션{Semi multi support torsion beam rear suspension}Semi multi support torsion beam rear suspension

본 발명은 토션 빔 리어 서스펜션에 관한 것이고, 보다 상세하게는 토션 빔 리어 서스펜션의 중앙에 충격을 흡수할 수 있는 부재가 제공되는 세미 다점 지지 후륜 토션 빔 서스펜션에 관한 것이다.The present invention relates to torsion beam rear suspension, and more particularly to a semi-multipoint support rear wheel torsion beam suspension provided with a member capable of absorbing shock at the center of the torsion beam rear suspension.

일반적으로, 자동차에 있어서의 서스펜션 시스템은 차체와 차륜사이에 존재하면서 이 2개의 강체를 하나 혹은 다수의 컨트롤아암으로 연결하여 상항 방향으로는 스프링과 쇽 업소오버에 의하여 지지되고, 기타 방향으로는 높은 강성과 유연성을 적절히 조화시킴으로써, 차체와 차륜사이의 상대운동을 기계적으로 적절히 조화시켜 주행중 노면으로부터 받는 진동과 충격을 흡수하여 승차감과 선회 안정성을 향상시키는 장치이다.In general, a suspension system in a vehicle exists between a body and a wheel, and connects the two rigid bodies with one or more control arms and is supported by springs and shock absorbers in the upward direction, and high in the other directions. By harmonizing rigidity and flexibility properly, the relative movement between the vehicle body and the wheel is mechanically balanced to absorb vibrations and shocks received from the road surface while driving, thereby improving ride comfort and turning stability.

이러한 현가장치는 노면으로부터의 입력에 대한 여러 부문의 성능을 만족시키기 위하여 다음의 3가지 조건이 요구되고 있다.In order to satisfy the performance of various sectors for the input from the road surface, the following three conditions are required.

첫째, 조정 안정성을 위하여 타이어는 이상적인 자세를 유지케 하여 노면에 대한 그립(grip)력을 극대화하고, 차체는 나름대로 최상의 자세를 유지하여 목적하는 차량 운동상태를 가능케 하여야 하며, 특히 어떠한 상태에서도 항상 다음 동작을 얻을 수 있는 순간력을 지님과 동시에 운전자의 의도하는 방향 및 순간 외에는 외부 입력에 의한 어떠한 거동도 허용하면 안 된다.First, the tire should maintain the ideal posture to maximize the grip force on the road, and the body should maintain the best posture in order to enable the desired vehicle movement state, especially in any condition At the same time, it must not have any momentary power to gain motion and allow any action by external inputs other than the driver's intended direction and moment.

둘째, 안락감을 위하여 어떠한 충격도 민첩하게 흡수할 수 있도록 하여 차내에 있는 탑승자들로 하여금 불쾌감을 느끼지 못하도록 하여야 한다.Secondly, for comfort, it should be possible to absorb any shock quickly so that passengers in the car may not feel uncomfortable.

셋째 충돌시 이의 충돌에너지의 흡수에 기여하도록 하여 충돌 안정성을 증대시킬 수 있도록 하여야 한다.Third, in case of collision, it should contribute to the absorption of its collision energy so that collision stability can be increased.

이러한 요구조건을 충족시킬 수 있는 서스펜션 시스템은 그 종류가 매우 다양하며, 그들 나름대로 꾸준한 발전이 거듭되고 있는데, 특히 최근에는 고출력 엔진의 등장과 더블어 소비자의 '주행의 재미(fun to drive)'에 대한 선호도가 급격히증가하기 시작함에 따라 운전자의 의지를 유쾌하게 표현할 수 있는 고성능 서스펜션의 시스템의 출현이 강력히 요구되고있다.There are many types of suspension systems that can meet these requirements, and their development is steadily growing, especially in recent years with the emergence of high-power engines and the 'fun to drive' of double-ear consumers. As preferences begin to increase rapidly, the emergence of a system of high-performance suspension that can express the driver's will pleasantly is strongly required.

그러나, 현재까지의 개발되어 사용되고 있는 트레일링 아암 타입, 토션 빔 액슬 타입, 스트러트 타입, 더블 위쉬본 타입과같은 리어 서스펜션 시스템으로는 상기 요구를 충분히 수용하기에는 불충분하다.However, rear suspension systems such as the trailing arm type, the torsion beam axle type, the strut type, and the double wishbone type, which have been developed and used to date, are insufficient to sufficiently satisfy the above requirements.

이에 따라 최근에는 적어도 3개 이상의 링크를 사용하여 노면으로부터 입력되는 충격 및 진동과, 차체의 진동을 이상적인 기구학적 운동으로 이들을 효과적으로 수용할 수 있는 멀티 링크 타입 서스펜션 시스템이 개발되어 양산차량에 적용되고있는 추세이다.Recently, a multi-link suspension system has been developed that can effectively accommodate shocks and vibrations input from the road surface using at least three links and vibrations of the vehicle body with ideal kinematic movements. It is a trend.

도 1은 종래의 토션 빔 리어 서스펜션의 구조를 개략적으로 도시한 도면이다. 도 1에 도시된 바와 같은 토션 빔 리어 서스펜션은 비교적 소형의 승용차 후륜에 사용된다.1 is a view schematically showing the structure of a conventional torsion beam rear suspension. The torsion beam rear suspension as shown in FIG. 1 is used for a relatively small passenger car rear wheel.

그러나, 상기된 바와 같은 종래의 토션 빔 리어 서스펜션은 가격은 저렴하고 구조가 간단하다는 장점은 있으나, 중대형 승용차에 사용되는 독립 현가식 서스펜셔에 비하여 승차감을 향상시키는데는 한계가 있다는 문제점이 있었다.However, the conventional torsion beam rear suspension as described above has the advantage of low cost and simple structure, but there is a problem in that the ride comfort is limited compared to the independent suspension suspension used for medium and large passenger cars.

따라서, 본 발명의 목적은 간단한 구조의 추가로 승차감을 향상시킬 수 있는 구조를 가지는 세미 다점 지지 후륜 토션 빔 서스펜션을 제공하는데 있다.Accordingly, it is an object of the present invention to provide a semi-multipoint supporting rear wheel torsion beam suspension having a structure which can further improve the riding comfort with the addition of a simple structure.
