The invention discloses a trailer gooseneck, which relates to the technical field of cargo transport vehicle equipment, and comprises a cross beam, a gooseneck frame of which the rear end is fixed with the cross beam, a traction pin disc and a movable beam which are arranged in the gooseneck frame, and a connecting seat hinged to the outer wall side of the movable beam, the traction pin disc and the cross beam are hinged to the front end and the rear end of the movable beam respectively, the movable beam is provided with a lifting oil cylinder used for driving the movable beam to rotate around the cross beam, and connecting rods are hinged between the traction pin disc and the connecting base and between the cross beam and the connecting base. According to the invention, the gooseneck frame is always kept horizontal in the lifting process, goods on the upper plane of the gooseneck frame do not slip off, the upper plane and the lower plane of the traction pin disc are kept horizontal, follow-up steering between the trailer axle and the gooseneck is also realized, and finally, the overall trafficability of a vehicle is greatly improved.
本发明公开了一种挂车鹅颈,涉及货物运输车辆设备技术领域,包括横梁,还包括后端与横梁相固定的鹅颈框架、设于鹅颈框架内部的牵引销盘和活动梁、以及铰接于活动梁外壁侧的连接座,所述牵引销盘和横梁分别与活动梁的前后两端相铰接,所述活动梁设有用于带动其绕横梁旋转的升降油缸,所述牵引销盘和横梁还均与连接座之间铰接有连杆。本发明不仅在使得鹅颈框架在升降过程中始终保持水平,鹅颈框架上平面的货物不存在滑落的危险的同时,使得牵引销盘上下平面均保证水平,还实现了挂车车桥与鹅颈之间的随动转向,最终极大地提升了整体的车辆通过性。
