The invention discloses a heavy traction seat structure, which is mounted on a tractor, and comprises a mounting disc fixed on the tractor, the mounting disc is provided with an inner cavity, and an opening is formed in the top of the inner cavity; the rotating disc is arranged in the inner cavity and is in rotating fit with the inner cavity, a mounting surface is formed on the top surface of the rotating disc, and the projection of the mounting surface is located in the projection of the opening in the vertical direction; and the traction seat is fixed on the turntable, the traction seat comprises a bracket fixed on the mounting surface and a panel positioned above the turntable, and the panel is rotationally connected to the bracket and is provided with a traction pin hole. Through the structural design, the rotary disc can rotate relative to the mounting disc, and when a vehicle turns and bears large friction force, the traction seat rotates to increase one degree of freedom in the rotation direction, so that the friction force between the panel and the trailer bottom plate is reduced, the abrasion of the panel is reduced, and the service life of the trailer is prolonged. The purposes of prolonging the service life of the traction seat and improving the driving safety are achieved.

    本发明公开了一种重型牵引座结构,安装在牵引车上,包括:安装盘,固定于牵引车上,安装盘具有一内腔,内腔的顶部形成一开口;转盘,其设于内腔中且与内腔转动配合,转盘的顶面形成一安装面,在上下方向上,安装面的投影位于开口的投影内;牵引座,固定于转盘上,牵引座包括固定于安装面上的支架及位于转盘上方的面板,面板转动连接于支架上且其设有一牵引销孔。通过此结构设计,使得转盘可相对于安装盘转动,当车辆转弯且受到比较大的摩擦力时,牵引座产生回转以使其在回转方向增加一自由度,从而减小面板与挂车底板之间的摩擦力,进而减小面板的磨损,达到延长牵引座使用寿命和提高行车安全性的目的。
