Abstract

PURPOSE: An impact absorbing damper structure effectively damps an instantaneous pressure increase generated at the lower end of an orifice by absorbing vibration or impact energy generated on running on an uneven road surfaces. CONSTITUTION: A vibration or impact energy generated on running on an uneven road surfaces is firstly absorbed to a spring and oil(3) and relieved. When a vehicle passes through a very rough section of a road, an upper and a lower pads(7a) absorb an impact due to an instantaneous pressure increase generated at the lower end surface of an orifice body(4). If a pressure applied to the surfaces of the upper and lower pads(7a) is higher than a predetermined pressure, a streamline form spring mounted between the pads(7a) implements a buffering actuation by being moved vertically, thereby absorbing an abrupt impact energy. Therefore, a ride comfort is improved.

충격흡수용 댐퍼구조{a damper for absorbing shock}Damper structure for shock absorption {a damper for absorbing shock}

본 발명은 차량용 현가장치에 장착되는 충격흡수용 댐퍼에 관한 것으로, 특히 댐퍼의 오리피스부를 개선시키어 하단에서 발생하는 순간적인 압력증가를 패드스프링을 이용하여 완화시키어 차량의 승차감을 개선시킨 충격흡수용 댐퍼구조에 관한 것이다.The present invention relates to a shock absorbing damper mounted on a vehicle suspension device, and in particular, by improving the orifice portion of the damper to alleviate the instantaneous pressure increase occurring at the bottom by using a pad spring to improve the ride comfort of the vehicle. It's about structure.

주지된 바와 같이 차량용 현가장치에는 충격흡수용 댐퍼가 차체프레임과 바퀴사이에 설치되어 있는바, 이 충격흡수용 댐퍼는 차량 주행시 노면으로부터 야기되는 각종 진동이나 충격에너지를 스프링과 댐퍼에서 흡수하여 승차감을 향상시키는 역할을 수행하는데, 종래 충격흡수용 댐퍼구조를 살펴보면, 도 1과 도 5에 도시된 바와 같이 상부(2)에는 스프링(1)이 지지대(9)에 안착되어 설치되고 이 스프링(1)이 설치된 상부(2)와 하부(10)는 실린더 결합방식으로 결합되되, 상기 상부(2)의 내부에는 오리피스구멍(105)이 형성된 C형부품(111)이 장착됨에 따라 이 내부에 있는 오일(3)이 상하로 이동될때 C형부품(111)의 오리피스구멍(105)을 통하여 오일이 이동되어 노면에서 발생되는 진동이나 충격에너지를 흡수하도록 되어 있었다.As is well known, a shock absorbing damper is provided between a vehicle body frame and a wheel in a suspension system for a vehicle. The shock absorbing damper absorbs various vibrations or impact energy generated from a road surface during driving of a vehicle by using springs and dampers to provide a ride comfort. Looking at the conventional shock absorbing damper structure, as shown in Figures 1 and 5, the upper part (2), the spring (1) is installed on the support (9) is installed and this spring (1) The upper part 2 and the lower part 10 are installed in a cylinder coupling method, and the C-type part 111 having an orifice hole 105 is mounted in the upper part 2 so that the oil in the inner part ( When 3) is moved up and down, the oil is moved through the orifice hole 105 of the C-shaped part 111 to absorb vibrations or impact energy generated on the road surface.

그러나 요철이 심한 노면구간이나 비포장도로 주행시 상기 오리피스구멍(105)은 이 오리피스구멍(105) 하단면의 오일통과를 방해하여 순간적으로 압력을 증가시킴에 따라 압력에너지가 충격에너지로 변화되어 승차감을 저하시키는 문제점이 있었다.However, when driving on a road section or an uneven road with severe unevenness, the orifice hole 105 obstructs the passage of oil in the bottom surface of the orifice hole 105 to increase the pressure instantaneously, thereby changing the pressure energy to impact energy, thereby reducing the riding comfort. There was a problem letting.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위하여 발명된 것으로, 주행시 불규칙한 노면에서 발생하는 진동 내지는 충격에너지를 흡수하면서 오리피스 하단에서 발생하는 순간적인 압력증가를 효과적으로 완충하여 차량의 승차감을 향상시킨 충격흡수용 댐퍼구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, while absorbing the vibration or impact energy generated from the irregular road surface during driving, the shock that effectively buffers the instantaneous pressure increase generated at the bottom of the orifice to improve the ride comfort of the vehicle The purpose is to provide an absorption damper structure.
