The invention discloses an amphibious motorbike ascending and descending
damper. The amphibious motorbike ascending and descending
damper comprises a
piston cylinder and a
piston rod. A low-pressure oil port and a high-pressure oil port are welded to the two ends of the side wall of the
piston cylinder respectively and communicated with an inner cavity of the
piston cylinder, a sliding piston is installed in the
piston cylinder in a sliding mode, an abrasion-proof
washer and an oil seal are embedded in each of the two ends of the outer wall of the sliding piston respectively, the
piston rod isconnected to the sliding piston through a thread, and an end sealing cover is installed at the end, closes to the low-pressure oil port, of the
piston cylinder. The amphibious motorbike ascending anddescending
damper has the advantages that the overall length can be adjusted through extension and contraction in use, the distances between wheels and a vehicle body can be adjusted, supporting canbe achieved, damping can also be carried out through a damping spring soaking in hydraulic oil in the advancing process, and the damping performance of a motorbike is improved; and the amphibious motorbike can freely switch the heights of wheel bodies in land and water environments and adapt to different environments, and practicability can be improved.
