Amphibious motorbike ascending and descending damper

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a lifting shock absorber for amphibious motorcycles. Background technique [0002] Shock absorbers improve driving comfort by absorbing shocks generated during driving or stopping. The shock absorbers currently on the market, especially those involving electric vehicles and motorcycles, are composed of springs and spring rods and the hydraulic system is fixed in length. There is no problem when using it on land, but in water Driving due to water resistance. It affects the driving speed of the vehicle. For this reason, it is necessary to raise the shock absorber to retract the tires and reduce water resistance. However, the shock absorbers on the market have a fixed length, and the height of the fixed tire remains unchanged. When driving in the water, it hinders the principle of fluid mechanics, increases the water resistance and reduces the speed of the vehicle. Therefo...

Problems solved by technology

However, the shock absorbers on the market have a fixed length, and the height of the fixed tire remains unchanged. When driving in the water, it hinders the principle of fluid mechanics, increases the water resistance and reduces the speed of the vehicle. Therefore, raising the shock absorber and driving the tires up to It is necessary to reduce resistance above the waterline, otherwise it will not be conducive to the popularization and use of amphibious motorcycles
