本文对最新研制的新型油气悬架结构、气室密封技术、高度调节技术及油气悬架半主动控制系统作了简单介绍。该套系统能够根据不同的路面适时改变油气弹簧阻尼 ,将整车加速度控制在规定值范围内 ,同时还可以实现车身高度调节等功能。该系统已在重型越野车上得到了应用。道路试验表明 ,装用半主动油气悬架后 ,整车的平顺性、操纵稳定性、通过性、机动性得到极大改善 In this paper, a brief introduction is given to the newly developed oil and gas suspension structure, gas chamber sealing technology, height adjustment technology and semi-active control system of oil-gas suspension. The system can change the oil and gas spring damping according to the different road, the vehicle acceleration control within the specified value range, but also can achieve the function of body height adjustment. The system has been used in heavy off-road vehicles. Road tests show that the installation of semi-active oil and gas suspension, the vehicle’s ride, handling stability, mobility, mobility has been greatly improved
