Description

Technical Field

[0001] The utility model relates to the technical field of dampers, in particular to an externally mounted threaded steering damper. Background Art

[0002] The steering damper, also known as the titanium ruler, is an automotive component that is mainly used to control the stability of the vehicle at high speeds. The function of the titanium ruler is to prevent the front of the vehicle from rotating in a large range in a short period of time, thereby reducing the swing of the vehicle at high speeds. When the driver encounters an uneven road surface at high speeds, the titanium ruler can attenuate the vibration, improve the stability of the vehicle, and make it easier for the vehicle to pass through the curve; the existing titanium ruler does not have an external thread when it leaves the factory, which is not convenient for its installation and fixation in subsequent use.
