The invention relates to an air spring assembly which comprises an air spring body, a piston rod, a piston rod, a piston rod and a spring body, a cavity is formed in the top end of the air spring body, and the piston rod of the air spring body penetrates through the cavity; the vibration reduction seat is installed in the cavity, a sealing cover is installed in an opening in the top end of the vibration reduction seat in an embedded mode, a bottom groove is formed in the bottom face of the sealing cover, an electromagnetic coil is installed in the bottom groove, and magnetic flow channels are formed in the top face of the electromagnetic coil and the top face of the sealing cover; the first ring is located on the top of the sealing cover, the second ring is coaxially arranged in the first ring, the first ring is assembled in the cavity, and a flexible diaphragm is installed between the first ring and the second ring. The vehicle impact force and attenuation force can be attenuated through the magnetic current damping and the vibration reduction seat together, and the problems that traditional vibration reduction depends on rubber vibration isolation, the vibration isolation effect is poor, road surface vibration is easily transmitted to vehicle sound through a piston rod, and abnormal sound in a vehicle is caused are solved.
本申请涉及一种空气弹簧总成,其包括:空气弹簧体,所述空气弹簧体的顶端开设有腔室,所述空气弹簧体的活塞杆贯穿所述腔室;减振座,所述减振座安装于所述腔室,所述减振座的顶端开口嵌入安装有封盖,所述封盖的底面开设有底槽,所述底槽内安装有电磁线圈,所述电磁线圈和所述封盖的顶面均开设有磁流通道;位于所述封盖的顶部环一以及同轴设置于所述环一内的环二,所述环一装配于所述腔室,且所述环一和所述环二之间安装有柔性膜片。可以通过磁流阻尼和减振座共同实现衰减车辆冲击力和衰减力,避免了传统减振依赖于橡胶隔振,其隔振效果差,易导致路面振动通过活塞杆传递至车声,引起车内异响的问题。
