The invention discloses a semitrailer frame tail connecting device, and belongs to the technical field of semitrailer frame connection, the semitrailer frame tail connecting device comprises a slow connecting assembly and two sets of direction adjusting assemblies, each direction adjusting assembly comprises a fixing column and a special-shaped ball socket fixedly connected to the outer wall of one end of the fixing column, and four fan-shaped cutting grooves are circumferentially formed in the inner wall of each special-shaped ball socket; the outer wall of one side of the special-shaped ball socket is provided with a fillet, the inner wall of the special-shaped ball socket is provided with a sliding ball, the outer wall of the sliding ball is in rolling connection with a first ball head, the outer wall of the first ball head is fixedly connected with a movable column, and the outer wall of the special-shaped ball socket is fixedly connected with four externally-arranged frames arranged circumferentially. By arranging the special-shaped ball socket, after the connecting device is connected with the tail of the vehicle frame, in the driving process of the vehicle body, once the movable column moves, the movable column can enter a fan-shaped cutting groove of the special-shaped ball socket, and compared with a ball socket and ball head connecting mode in the traditional technology, the movement range of the movable column can be enlarged through the arrangement of the special-shaped ball socket; therefore, the connecting device can meet the requirement of multi-angle adjustment.

    本发明公开了半挂车车架尾部连接装置,属于半挂车车架连接技术领域,包括缓接组件和两组调向组件,调向组件包括固定柱和固定连接于固定柱一端外壁的异形球窝,异形球窝内壁设置有圆周排列的四个扇形切割槽,异形球窝一侧外壁设置有圆角,异形球窝内壁设置有滑珠,滑珠外壁滚动连接有第一球头,第一球头外壁固定连接有活动柱,异形球窝外壁固定连接有四个圆周排列的外置架。本发明通过设置异形球窝,其中当该种连接装置连接车架尾部之后,车体处于行驶过程中,一旦活动柱运动,能够进入异形球窝的扇形切割槽内部,相比传统技术中的球窝球头连接方式,异形球窝的设置能够扩大活动柱的运动范围,从而使得该种连接装置满足多角度调节的需求。
