The invention discloses a damper for a pantograph type current collector. The damper comprises a first cylinder body, a second cylinder body, a piston assembly and a first end cover assembly. The second cylinder body is arranged on the first cylinder body in a sleeving mode, and a containing cavity capable of containing media is formed between the second cylinder body and the first cylinder body.The piston assembly comprises a piston and a piston rod which are connected. The piston divides the first cylinder body into a roded cavity and a rodless cavity which are used for containing media. The rodless cavity communicates with the containing cavity. A first passage and a first buffer assembly are arranged on the piston. A second passage and a second buffer assembly are arranged on the piston rod. The first end cover assembly comprises a guide base, a framework oil seal and a threaded fixing piece. An air bag is further arranged in the containing cavity so that the pantograph type current collector can be kept stable. According to the damper for the pantograph type current collector, through the first buffer assembly and the second buffer assembly, the damper can move gently when the pantograph type current collector ascends and descends; and the air bag is further arranged in the containing cavity, when vibration occurs, the air bag can be matched with the media to attenuate the vibration, and the stability of the pantograph type current collector is guaranteed.

    本发明公开一种用于受电弓的阻尼器,包括第一筒身、第二筒身、活塞组件和第一端盖组件;第二筒身套设在第一筒身上,且第二筒身和第一筒身之间形成能容纳介质的容纳腔;活塞组件包括相连接的活塞和活塞杆;活塞将第一筒身分隔成用于容纳介质的有杆腔和无杆腔;无杆腔与容纳腔连通;活塞上设有第一通路以及第一缓冲组件;活塞杆上设有第二通路以及第二缓冲组件;第一端盖组件包括导向座、骨架油封和螺纹固定件;容纳腔内还设有气囊,便于保持受电弓的平稳。本发明通过第一缓冲组件和第二缓冲组件实现阻尼器在受电弓升弓和降弓时,能平缓运动;容纳腔内还设有气囊,在发生振动时,气囊能与介质配合对振动进行衰减,保证受电弓的平稳。
