Embodiment 1

[0050] combine Figure 1 to Figure 7 , the damping force adjustable motorcycle shock absorber of this embodiment includes a piston cylinder, a piston and a piston rod, the piston is equipped with an extension valve, the extension valve is connected with an extension valve channel, the piston rod is provided with a radial through hole, and the radial The through hole communicates with the stretching valve passage, the piston rod is provided with an axial through hole, and a thimble for adjusting the flow rate of the radial through hole is arranged in the axial through hole. The size of the radial through hole on the piston rod is adjusted by the thimble, thereby changing the flow rate of the oil in the extension valve channel, thereby adjusting the restoring damping force. The preload of the shock absorber can be adjusted to meet the riding requirements of different riders.

[0051] The piston of this embodiment is equipped with a first extension valve, the first extension val...

Embodiment 2

[0060] The motorcycle shock absorber with adjustable damping force in this embodiment includes a piston cylinder, a piston and a piston rod. The piston is equipped with an extension valve. The hole communicates with the channel of the stretching valve, the piston rod is provided with an axial through hole, and a thimble for adjusting the flow rate of the radial through hole is arranged in the axial through hole. The size of the radial through hole on the piston rod is adjusted by the thimble, thereby changing the flow rate of the oil in the extension valve channel, thereby adjusting the restoring damping force. The preload of the shock absorber can be adjusted to meet the riding requirements of different riders.

[0061] The piston of this embodiment is provided with only one extension valve, and the extension valve is provided with only one channel, that is to say, the radial through hole of the piston rod is connected in series with the channel provided on the piston, so tha...

Abstract

The invention discloses a motorcycle shock absorber with damping force adjustable. The problems that an existing shock absorber is poor in adjusting capacity of damping force, and the damping force cannot be adjusted and restored are solved. The motorcycle shock absorber comprises a piston cylinder, a piston and a piston rod, the piston is provided with a rebound valve, and the rebound valve is communicated with a channel. A radial through hole is formed in the piston rod, and is communicated to the channel, and an ejector pin used for adjusting the flow of the radial through hole is arranged inside the piston rod. The flow of the radial passing of the piston rod is adjusted through the ejector pin, then the flow of the channel of the rebound valve is adjusted, and therefore the damping force is adjusted and restored, the riding feedings of different riders are met, and the shock absorption performance of the shock absorber is improved. The motorcycle shock absorber is suitable for the shock absorption of motorcycles, and especially suitable for the shock absorption of racing motorcycles.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a motorcycle shock absorber with adjustable damping force. The invention is suitable for shock absorption of motorcycles, especially for racing motorcycles. Background technique [0002] Motorcycles have developed from cities to rural areas, from high-end consumer goods to transportation and transportation vehicles, and then motorcycles have gradually returned to cities from rural areas. As sports, leisure, and competition supplies, motorcycle racing is also in full swing. [0003] In order to alleviate and attenuate the impact and vibration of the motorcycle due to the unevenness of the road during driving, to ensure the smoothness and comfort of driving, and to improve the service life of the motorcycle and the stability of the operation, the motorcycle is equipped with a shock absorber. Vibrator device. [0004] Motorcycles have high requirements on the performance of the shock absorber, d...
