The invention discloses a trailer traction mechanism protection frame, and belongs to the technical field of semitrailers. The trailer traction mechanism protection frame comprises a front protection frame body and a rear protection frame body which are connected to the bottom of a trailer carriage and arranged on the front side and the rear side of a saddle respectively so as to avoid unhooking of a trailer, an interlayer is arranged on the front portion of the trailer carriage, and a turnover mechanism is arranged in the interlayer; and the front protective frame is connected with the turnover mechanism. When the main frame and the trailer compartment are picked and hung, the turnover mechanism turns over the front protection frame into the interlayer, and the main frame is separated from the front end of the trailer compartment to be picked and hung. When the main frame is hung on the trailer carriage, the front protection frame is arranged in the interlayer, after hanging is completed, the turnover mechanism turns over the front protection frame out of the interlayer, and the front protection frame and the rear protection frame are arranged on the front side and the rear side of the saddle respectively. The safety risk caused by the fact that a main vehicle saddle locking mechanism or a trailer traction pin is accidentally damaged, slides forwards out of control to impact a cab or is abnormally separated in the running process can be effectively prevented.
本发明公开了一种挂车牵引机构防护架,属于半挂车汽车技术领域。本发明的挂车牵引机构防护架,包括连接于挂车车厢底部,并分列鞍座前和后侧的前防护架和后防护架,以避免挂车脱钩,挂车车厢的前部设置隔层,隔层内置翻转机构;前防护架与翻转机构连接。主车架与挂车车厢摘挂时,翻转机构将前防护架翻转至隔层内,主车架由挂车车厢的前端分离摘挂;主车架与挂车车厢上挂时,前防护架在隔层内,上挂完成后,翻转机构将前防护架翻转出隔层外,前防护架和后防护架分列鞍座前和后侧。能达到有效防止主车鞍座锁止机构或挂车牵引销发生意外损坏,失控向前滑动冲击驾驶室,或行驶中异常分离造成安全风险的效果。
