The invention discloses a self-locking type carriage connecting structure for a semitrailer, and relates to the technical field of semitrailer connecting pieces, the self-locking type carriage connecting structure comprises a traction seat body installed on a tractor and a traction hook fixed on a carriage, a V-shaped clamping groove is formed in the upper surface of the traction seat body in a penetrating mode, and the traction hook is clamped in the V-shaped clamping groove; an arc-shaped groove is formed in the inner wall of the V-shaped clamping groove in a penetrating mode, and an arc-shaped clamping base is arranged in the arc-shaped groove and used for clamping and fixing the traction hook. The position of a tractor is adjusted, so that a traction hook is clamped in a V-shaped clamping groove formed in a traction seat body, then an arc-shaped clamping seat is driven by a driving assembly to lock and limit the traction hook located in the V-shaped clamping groove, movement of the traction hook is limited, and rapid connection is achieved; and the driving assembly is automatically locked and positioned, so that the driving assembly does not move when being used, and the stability of locking and fixing the traction hook by the arc-shaped clamping seat is improved.
本发明公开了一种半挂车用自锁式车厢连接结构,涉及半挂车连接件技术领域,包括:安装于牵引车上的牵引座体和固定在车厢上的牵引挂钩,所述牵引座体上表面贯穿开设有V型卡槽,其牵引挂钩卡合与V型卡槽内,所述V型卡槽内壁贯穿开设有弧形槽,所述弧形槽内设置有弧形卡接座,其用于对牵引挂钩进行卡接固定。本发明中调节牵引车位置,使得牵引挂钩卡接在牵引座体上开设的V型卡槽内,然后通过驱动组件带动弧形卡接座对位于V型卡槽内的牵引挂钩进行锁合限位,限制牵引挂钩移动,实现了快速连接,配合设置有自锁组件,对驱动组件进行自动锁合定位,使得驱动组件在使用时,不会勿动,提高了弧形卡接座对牵引挂钩锁合固定的稳定性。
