8results about How to "Avoid torsional deformation" patented technology

This application relates to the field of vehicle chassis and provides a suspension structure and a vehicle. The suspension structure of this application includes an outer tube, an inner core disposed within the outer tube, and an elastic body disposed between the outer tube and the inner core. The elastic body has a first portion wrapped around the inner core and a second portion connected to the first portion. The second portion is disposed at the end of the inner core connected to the powertrain bracket, and when the inner core is connected to the powertrain bracket, the second portion can abut against the powertrain bracket. The suspension structure of this application can increase the friction between the elastic body and the powertrain bracket, and also increase the friction between the powertrain bracket and the inner core during the connection process, preventing the inner core from shifting. This effectively avoids torsional deformation of the elastic body, thereby improving the reliability of the elastic body and the overall suspension structure.

The application discloses a multi-angle welding device for steel plate processing, and relates to the field of metal welding equipment. The outer side of a bearing welding base body is provided with a hydraulic driving part, the output end of the hydraulic driving part is connected with a bearing butt joint assembly, and the upper end of the bearing butt joint assembly is used for placing a steel plate workpiece to be welded. The multi-angle welding device for steel plate processing is independently and synchronously driven to rotate the steel plate placed by the bearing butt joint assembly around the same rotary axis. When the hydraulic driving part pushes the corresponding steel plate upward to make the steel plate angularly move, the rotation angle of the steel plate and the stroke of the driving rod are in linear relationship. An operator can quickly calculate the extension amount of the driving rod according to the required included angle, and the repeated trial is not needed. The symmetrical adjustment mode makes the angle adjustment of the two steel plates not interfere with each other, and the adjustment process is stable and continuous. The adjustment can be realized in the range of 0-180 degrees, and the stable angular welding stability of the two groups of steel plates in angular contact can be ensured.
