The invention discloses an automobile suspension damping system, and relates to the technical field of automobile accessories. The automobile suspension damping system comprises a cylinder body, wherein a piston is slidably connected in the cylinder body, and an upper cavity and a lower cavity are formed between the top of the piston and the cylinder body and between the bottom of the piston and the cylinder body correspondingly. A protection barrel fixedly connected with a piston rod is arranged on the outer side of the cylinder body, when the piston rod slides in the cylinder body, the piston rod drives the protection barrel to slide on the outer side of the cylinder body, limiting blocks extending into the cylinder body are fixedly arranged at the two ends of the bottom of the inner side of the protection barrel correspondingly, and limiting grooves matched with the limiting blocks are formed in the two ends of the outer side of the cylinder body correspondingly, so that when the protection barrel stretches out and draws back along with the piston rod, the protection barrel can be quite well attached to the outer wall of the cylinder body, the piston rod is well protected in anall-around mode when the piston rod stretches out of the cylinder body, and the problem that external impurities adhere to the piston rod, and thus the service life of the piston rod is shortened is solved effectively.

    本发明公开了一种汽车悬架减震系统,涉及汽车配件技术领域,包括缸体,所述缸体内部滑动连接有活塞,所述活塞顶部和底部分别与缸体之间形成上腔和下腔。本发明通过在缸体的外侧设置有与活塞杆固定连接的保护筒,当活塞杆在缸体内部滑动的时候,活塞杆带动保护筒在缸体外侧进行滑动,且保护筒内侧底部的两端皆固定设置有延伸至缸体内部的限位块,且缸体外侧两端皆设置有与限位块相配合的限位槽,进而在保护筒随着活塞杆伸缩的时候,保护筒能够很好的贴合在缸体的外壁上,进而很好的保护了活塞杆在伸出缸体时,对活塞杆全方位的保护,有效的避免了外界杂质与活塞杆相粘连,导致活塞杆寿命降低的问题。
