Description

Technical Field

For example, the steering damper of the motorcycle is installed at the handlebar of the motorcycle. The function of the steering damper is: when driving at high speed, due to the action of the road surface or human external force, the behavior of attempting to turn the handlebar irregularly and in a large range in a short period of time is damped. When the motorcycle is at high speed, it can also prevent the front of the motorcycle from swinging excessively. When turning at high speed, it can attenuate the vibration brought to the driver by the excessive swing of the handlebar due to uneven road surface, increase the stability of the handlebar during vehicle driving, and improve driving comfort.

[0004] The above disclosed "detachable cradle shock absorbing device with friction damping" still has the following technical problems during its use: First, the butterfly thread sleeve and the screw are detachable structures. This combination structure is very likely to cause poor fastening, and even the butterfly thread sleeve and the screw may fall off due to shaking during vehicle driving; Second, a frame card is provided between the two friction plates, and the frame card is clamped and fastened between the bottom plate and the butterfly thread sleeve and the screw, and prevents sliding by means of anti-slip protrusions and concave holes, but this method is not practical in practice. In actual use, there is still a problem that the frame card is easy to loosen, resulting in unsatisfactory shock absorption and friction damping effects; third, a stopping protrusion is provided on the bottom surface of the upper mounting frame, and a sleeve matching the stopping protrusion is provided on the bottom plate, and the sleeve is clamped on the stopping protrusion. In actual use, this method is prone to the sleeve being misplaced or falling off from the stopping protrusion, resulting in unsatisfactory shock absorption and friction damping effects and time-consuming and labor-intensive; fourth, the stop washer and the nut are directly fastened, which not only has poor fastening properties, but also affects its aesthetics.
