[0002] Motorcycle shock absorbers can rapidly attenuate impact and vibration caused by vehicle weight, load, and various road conditions, significantly improving the motorcycle's shock absorption performance and enhancing riding comfort, stability, and safety to varying degrees. Existing motorcycle shock absorbers use hydraulic oil to act as a buffer, and the hydraulic oil pressure determines the piston rod's downward and rebound speeds. Shock absorbers are typically equipped with a downward pressure adjustment mechanism but lack a rebound adjustment mechanism, resulting in an unadjustable rebound speed and impacting shock absorber performance.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: the shock absorber downward pressure rebound speed regulation component is characterized in that it includes a downward pressure component and a rebound component, and the downward pressure component and the rebound component both include a hexagonal seat, an adjusting shaft core and an adjusting seat, the adjusting seat is connected to the lower section of the center hole of the hexagonal seat, and the adjusting seat is provided with radial oil holes and axial oil holes that are mutually conductive, the adjusting shaft core can rotate circumferentially, and the axial limit is set in the center hole of the hexagonal seat, and the upper end of the adjusting shaft core is provided with an adjusting button. The lower end of the joint shaft core is provided with a conical head that extends into the axial oil hole of the adjusting seat. The conical head can be circumferentially linked and axially moved and is set at the lower end of the adjusting shaft core.

[0005] The adjusting shaft core is provided with a radial hole, in which a steel ball and a spring are arranged. The spring is pressed by the steel ball. The inner circle of the adjusting seat corresponding to the steel ball is provided with a circle of grooves distributed at intervals, and the steel ball can roll along the groove to make a sound.

[0006] The plug of the rebound assembly is also provided with a circle of axially conductive second oil circuit, which is located on the inner side of the first oil circuit. The upper end of the corresponding plug is equipped with an upper valve plate group, which includes several layers of upper valve plates that are pressurized between the plug and the adjustment seat. The bottommost upper valve plate completely covers the upper port of the second oil circuit, and the inner end of the bottommost upper valve plate is pressurized by the upper valve plate.
