The utility model discloses an air damping spring type large vehicle traction device, and belongs to the technical field of vehicle traction. An air damping spring type large vehicle traction device comprises a front traction beam and a rear traction beam hinged to the front traction beam, and the rear traction beam comprises a rear beam body and a cylinder fixedly connected to the rear beam body; one end of the traction rod is hinged to the front traction beam, a piston is fixedly connected to the traction rod and divides an inner cavity of the cylinder body into two damping cavities, damping parts are arranged in the two damping cavities, a through flow guide channel is formed in the piston, and the flow guide channel communicates with the two damping cavities; first-stage buffering is formed through the elastic force of the elastic damping piece, in the buffering process, along with the movement of the piston, gas in the two cavities is exchanged through the flow guide channel, and therefore the second-stage buffering and two-stage buffering mode is formed, and the buffering effect can be improved while the special strength of the traction rod is not increased. And a high buffering effect is still achieved for high impact force of braking of large vehicles.

The utility model relates to the related technical field of rubber half tracks, in particular to a rubber half track of an all-terrain profiling structure, which comprises a track, a protective plate is fixedly connected to the surface of one side of the track, a buffer mechanism is arranged in the track, a tire is rotatably connected to the surface of one end of the track, and the tire is connected with a rubber belt. A mounting mechanism is arranged on the surface of one side of the tire. According to the rubber half track of the all-terrain profiling structure, through the arrangement of the connecting plates, the first bolts, the damping hydraulic devices, the springs and the buffering plates, the rubber half track of the all-terrain profiling structure has good buffering and damping functions, and in the actual using process, the connecting plates are tightly connected with the track body; the first bolts play a role in fixing the connecting plates and the track body, the stability of the whole structure is guaranteed, and due to the combined effect of the damping hydraulic devices and the springs, when the rubber half track of the all-terrain profiling structure encounters uneven terrains, the rubber half track can be fixed.

This invention relates to the field of yarn tension control technology for winding machines, providing a pre-tensioning device and control method for winding machines, aiming to solve the quality problems caused by tension fluctuations in high-twist yarns during the winding process. The pre-tensioning device includes a fixed frame, a movable frame, a torque spring, an adjusting nut, and a plastic bearing. Rotating the adjusting nut changes the preload of the torque spring on the movable frame, thereby adjusting the output tension. The device utilizes the resilience of the torque spring to buffer and compensate for yarn tension fluctuations, reducing yarn vibration and lowering the probability of yarn kinking, webbing, and bobbin defects. The control method includes steps such as yarn preparation, yarn insertion, tension application, winding, yarn detection, and cutting, ensuring stable yarn tension and improving bobbin quality. This invention has a simple structure, low cost, is easy to install and maintain, and is suitable for various yarn types and process requirements.
