The invention relates to a high-strength unpowered trailer frame which comprises a frame assembly, the frame assembly comprises a frame beam, a fixed cross beam, a movable cross beam assembly, a telescopic supporting beam and a traction frame assembly, and the traction frame assembly is fixedly arranged at the front end of the frame beam; each movable cross beam assembly comprises a middle cross beam, a side cross beam and a lifting main beam, the middle cross beams are arranged in the centers of the frame beams, the lifting main beams penetrate through the centers of the middle cross beams of the movable cross beams, the two ends of each lifting main beam are embedded into the lifting openings respectively and are provided with threaded connection bases, and the two threaded connection bases are arranged on the lead screws in a sleeving mode respectively and are in threaded connection with the lead screws; the two ends of the middle beam are movably connected with one ends of the side beams respectively, and the other ends of the side beams are hinged to the inner walls of the frame beams respectively. Therefore, the form of the movable cross beam assembly is changed, the frame can meet the use requirement of a yacht trailer frame and can also meet the use requirement of a platform trailer frame, and the practicability of the frame is improved.

    本发明涉及一种高强度无动力拖挂车车架,包括车架总成,车架总成包括框架梁、固定横梁、活动横梁组件、伸缩支撑梁以及牵引架组件,框架梁前端固定设置牵引架组件;活动横梁组件均包括中横梁、侧横梁以及升降主梁,中横梁设置于框架梁的中心,活动横梁的中横梁中心贯穿设置升降主梁,升降主梁的两端分别嵌入至升降口中并设有螺纹连接座,两个螺纹连接座分别套设在丝杆上并与之螺纹连接;中横梁的两端分别活动连接一个侧横梁的一端,侧横梁的另一端分别与框架梁内壁铰接相连。从而改变活动横梁组件形态,使车架既能够满足游艇拖车架的使用需求,也能满足平板拖车架的使用需求,提高了车架的实用性。
