본 고안은 자동차의 스트러트 아암 상부 지지장치에 관한 것으로서, 보다 상세하게는 스트러트 아암의 상단과 자체의 연결부에 개재되는 부시의 경도를 자동차의 주행조건에 따라 가변적으로 조정할 수 있도록 함으로써, 최적의 조종성과 승차감을 얻을 수 있도록 한 자동차의 스트러트 아암 상부 지지장치에 관한 것이다.The present invention relates to a strut arm upper support device of a vehicle, and more particularly, by adjusting the hardness of the bush interposed between the upper end of the strut arm and its own connection part in accordance with the driving conditions of the vehicle, thereby providing optimum maneuverability and The present invention relates to a strut arm upper support device for a vehicle to obtain a ride comfort.
잘 알려진바와 같이, 자동차에 있어서의 스트러트 아암은 맥퍼슨 타입(MacPherson Type)독립 현가장치의 구성부품으로서, 제 1 도에서와 같이 쇽업소오버(2)와 스프링(3)의 조립체로 구성되어 그의 상단은 차체에 현가 지지되고 그의 하단에는 휠 지지체가 결합된다.As is well known, the strut arm in a motor vehicle is a component of a MacPherson Type independent suspension, consisting of an assembly of a shock absorber 2 and a spring 3, as shown in FIG. The suspension is supported by the vehicle body and the wheel support is coupled to the lower end thereof.
상기와 같은 스트러트 아암(1)을 차체와 연결함에 있어서는 탄성체인 고무부시가 개재 설치되는데, 이와같은 고무부시는 자동차의 승차감과 조종 안정성에 많은 영향을 미치게 된다.In connecting the strut arm 1 with the vehicle body, a rubber bush which is an elastic body is interposed. Such a rubber bush greatly affects the riding comfort and steering stability of the vehicle.
즉, 휠로부터 전달되는 진동이 쇽업소오버와 스프링에 의해 흡수된 후에는 바로 고무부시를 통해 차체에 전달되어지는 바, 이의 고무부시의 특성에 의하여 승차감 및 조종 안정성이 크게 좌우되게 된다.That is, after the vibration transmitted from the wheel is absorbed by the shock absorber and the spring, it is immediately transmitted to the vehicle body through the rubber bush, and the ride comfort and the steering stability are largely influenced by the characteristics of the rubber bush.
이에따라 상기의 고무부시의 특성은 평상시의 시가지 주행이나 도로가 양호하지 못한 곳에서의 주행하는 경우에는 노면으로부터의 충격이 민감하게 느껴지므로 승차감이 보다 중요하게 되어 노면으로부터의 충격을 부드럽게 흡수할 수 있는 낮은 경도의 특성이 요구된다.Accordingly, the characteristics of the above-mentioned rubber bush is that the impact from the road surface is sensitive when driving in a normal city or a road where the road is not good, so the riding comfort becomes more important and the shock from the road surface can be smoothly absorbed. Low hardness properties are required.
그리고 고속 주행시에는 안정성을 유지하기 위하여 승차감 보다는 조종성능과 안정성능이 보다 중요한 요소가 되므로 높은 경도의 특성이 요구된다.In addition, high-speed driving requires high hardness because the steering performance and stability are more important factors than the riding comfort to maintain stability.
그러나 종래의 고무부시에 있어서는 그 특성이 하나의 경도만을 유지하게 되는 바, 중속이하의 주행에 승차감이 좋으면 고속 주행시에 안정성이 결여되고, 반대로 고속 주행시 안정성이 있으면 종속이하의 주행에서 승차감이 결여된다는 문제점이 있었다.However, in the conventional rubber bush, its characteristic is to maintain only one hardness. If the riding comfort is good for driving under medium speed, the stability is poor at high speed driving. On the contrary, if there is stability at high speed driving, the riding comfort is poor at subordinate driving. There was a problem.
또한, 상기와 같은 문제점을 해결하고자 하는 수단으로는 부시의 적정부위에 이물질을 삽입하거나 전후 형상을 다르게 하는 등의 수단이 이용되고 있으나, 이들 또한 상기와는 마찬가지로 고무부시의 특성을 가변시킬 수 있는 수단이 못되어 근본적인 치유책이 될 수 없었다.In addition, as a means to solve the above problems, such as inserting the foreign matter in the appropriate portion of the bush or a means for changing the shape before and after are used, these also can change the characteristics of the rubber bush as well as the above It could not be a means of healing by its means.
따라서 본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 수단으로 안출된 것으로서, 본 고안의 목적은 스트러트 아암의 상단과 차체의 연결부에 개재되는 부시의 경도를 자동차의 주행조건에 따라 가변적으로 조정할 수 있도록 함으로써, 최적의 조종성과 승차감을 얻을 수 있도록 한 자동차의 스트러트 아암 상부 지지장치를 제공하려는 것이다.Therefore, the present invention is conceived as a means for solving the conventional problems as described above, the object of the present invention is to adjust the hardness of the bushing interposed between the upper end of the strut arm and the vehicle body in accordance with the driving conditions of the vehicle In order to provide optimum maneuverability and comfort, the strut arm support of the vehicle is provided.
