The invention relates to the technical field of sled vehicles, in particular to a torsion limiting and automatic returning structure of a sled frame with a rudder, the sled frame and a sled vehicle. A torsion limiting and automatic returning structure of a sled frame with a rudder comprises a front frame, and the front frame is provided with a mounting hole and a mounting base. The limiting plate is arranged on the front frame, a rotating structure is arranged on the limiting plate, and the rotating structure is located below the mounting base; the rear frame is provided with a middle shaft and limiting pins located on the two sides of the middle shaft, the middle shaft penetrates through the mounting hole, and the limiting pins are inserted into the rotating structure; the elastic part is arranged in the mounting base, the bottom of the elastic part corresponds to the limiting pin, and after the rear frame is stressed to rotate, the limiting pin automatically returns to the initial state under the action of the elastic part. And the front frame and the rear frame can quickly and automatically return, so that the grounding property of four sliding blades of the rudder sleigh in the training and competition process is ensured, the agility and controllability of the rudder sleigh are improved, and the turning speed when a curve returns to a straight road is improved.
本发明涉及雪橇车技术领域,具体涉及一种有舵雪橇车架的扭转限位及自动回位结构、车架、雪橇车;有舵雪橇车架的扭转限位及自动回位结构,包括前车架,前车架上设有安装孔和安装底座;限位板,设于前车架上,且在限位板上设有转动结构,转动结构位于安装底座的下方;后车架,后车架上设有中间轴和位于中间轴两侧的限位销,中间轴贯穿安装孔,限位销插置于转动结构内;弹性件,设于安装底座内,且弹性件的底部与限位销对应设置,后车架受力转动后,限位销在弹性件的作用下自动回复至初始状态。前车架和后车架能够迅速自动回位,保证了训练及比赛过程中的有舵雪橇四个滑刃的接地性,提升有舵雪橇的敏捷性及操控性,提升弯道回归直道时的过弯速度。
