The invention relates to the technical field of semitrailer parts, in particular to a semitrailer traction seat, which comprises a traction seat main body, a manual shifting piece, a traction rod and a traction rod, a mounting base is rotatably mounted on the inner wall of the bottom end of the traction seat main body, and a mounting groove is formed in the front wall of the traction seat main body and extends to the center of the traction seat main body; and one end of the manual shifting piece extends into the traction seat main body and is fixedly connected with an electric telescopic rod. By arranging the buffering mechanism, after a traction pin extrudes a top plate, a pressing column can drive a connecting plate to extrude an air bag, at the moment, the air bag can buffer the connecting plate, the horseshoe-shaped saddle is prevented from being damaged, a fourth spring between two buffering rods can further conduct buffering in the process that the buffering rods move towards the two sides, and the buffering effect is improved. The buffering effect can be improved, collision between the traction pin and the horseshoe-shaped saddle can be relieved, and long-term use of the horseshoe-shaped saddle and the traction pin is facilitated.

    本发明涉及半挂车零部件技术领域,具体为一种半挂车牵引座,包括,牵引座主体,所述牵引座主体底端的内壁上转动安装有安装底座,所述牵引座主体的前壁上开设有安装槽,且安装槽延伸至牵引座主体的中心处,还包括:手动拨片,所述手动拨片的一端延伸至牵引座主体内固定连接有电动伸缩杆。本发明通过设置缓冲机构,当牵引销对顶板进行挤压后,按压柱能够带动连接板对气囊进行挤压,此时气囊能够对连接板进行缓冲,避免马蹄形鞍座受损,且两个缓冲杆之间的弹簧四能够在缓冲杆向两侧移动的过程中进一步进行缓冲,能够提高缓冲效果,能够减缓牵引销与马蹄形鞍座之间的碰撞,有利于马蹄形鞍座以及牵引销的长期使用。
