The invention relates to the technical field of semitrailer parts, and discloses a wear-resistant semitrailer traction seat. The traction seat comprises a saddle, and the center of the top of the saddle is rotationally connected with a rotating shaft through a ball bearing. The end, away from the saddle, of the rotating shaft is fixedly connected with a circular mounting plate. A circular wear-resistant plate is arranged at the top of the mounting plate. The lower surface of the wear-resistant plate is fixedly connected with four clamping blocks which are annularly and uniformly distributed. Four clamping grooves which are annularly and evenly distributed are formed in the upper surface of the mounting plate. The clamping blocks and the clamping grooves are matched with each other and arranged in a clamped mode. Sliding grooves are formed in the side walls of the clamping grooves, springs are fixedly connected to the groove bottoms of the sliding grooves, the other ends of the springsare fixedly connected with moving blocks matched with the sliding grooves, and the moving blocks are in sliding connection with the sliding grooves. According to the wear-resistant semitrailer traction seat, the abrasion resistance of the traction seat is effectively improved, the wear-resistant plate can be conveniently and rapidly disassembled and assembled according to the abrasion degree, thenthe traction seat is effectively protected, and the service life is prolonged.
本发明涉及半挂车零部件技术领域,且公开了一种耐磨半挂车牵引座,包括鞍座,鞍座顶部的中心处通过滚珠轴承转动连接有转轴,转轴远离鞍座的一端固定连接有圆形的安装板,安装板的顶部设有圆形的耐磨板,耐磨板的下表面固定连接有四个呈环形均匀分布的卡块,安装板的上表面开设有四个呈环形均匀分布的卡槽,卡块与卡槽相匹配,且卡合设置,卡槽的侧壁上开设有滑动槽,滑动槽的槽底固定连接有弹簧,弹簧的另一端固定连接有与滑动槽匹配的移动块,且移动块与滑动槽滑动连接。该耐磨半挂车牵引座,不仅有效提高牵引座的耐磨性,而且使得耐磨板方便根据磨损程度进行快速拆装,进而有效对牵引座进行防护,提高使用寿命。
