Description

Inversion front shock absorber capable of laterally adjusting damping Technical Field The invention relates to the technical field of shock absorbers, in particular to an inverted front shock absorber with side damping adjusting function. Background At present, the front shock absorber of the vehicles such as motorcycles, electric vehicles and the like mostly adopts an inverted structure, has the advantages of high rigidity, quick response and the like, and plays an important role in buffering road impact in the running process of the vehicles. However, most of the damping forces of the existing inverted front shock absorbers are fixedly arranged, and the design is difficult to meet the different requirements of different road conditions (such as a smooth road, a bumpy mountain road, a wet slippery road surface and the like) and different riding weights and driving habits on the damping characteristics of the shock absorbers. For example, a lower damping force may provide a more comfortable ride experience when the vehicle is traveling on a flat road surface, while a higher damping force may be required to ensure steering stability of the vehicle when traveling on a rough road surface or at high speeds. The fixed damping shock absorber cannot be dynamically adjusted according to real-time road conditions and riding conditions, and the problems that the shock absorption is too soft to cause overlarge fluctuation of a vehicle body and the operability is reduced, or the shock absorption is too hard to cause poor comfort, parts are easy to damage and the like are easily caused, so that the overall driving safety and driving feeling are influenced. Therefore, the inverted front shock absorber with adjustable damping is designed, so that a user can flexibly adjust the shock absorption performance according to actual road conditions and riding requirements. However, the damping adjustment knob of the conventional inverted front shock absorber is generally disposed at a top or bottom end position of the shock absorber. When the top end is arranged, as the front end of the motorcycle, the electric vehicle and other vehicles is generally provided with a plurality of parts such as an instrument panel, a brake handle and the like, the adjusting knob can be shielded, so that the operation space is limited when a user performs damping adjustment, the user needs to difficultly find the position of the knob and avoid peripheral parts, the damping adjustment becomes very inconvenient, and the adjusting range has certain limitation. When the damping device is arranged at the bottom end, the damping device needs to be bent or even crouched down to operate, the adjusting process is very inconvenient, in addition, the bottom end is close to the ground and is easy to be corroded by pollutants such as muddy water, dust and the like, the problems of knob clamping stagnation, adjustment accuracy reduction and the like possibly occur after long-term use, and the reliability and the service life of damping adjustment are affected. Aiming at the problems, the invention designs the novel inverted front shock absorber arranged on the side surface of the damping adjusting knob, so that a rider can adjust the damping size on the side surface of the shock absorber, and the defects of inconvenient operation, easy space limitation or pollution erosion and the like caused by the arrangement of the top end or the bottom end of the traditional damping adjusting knob are overcome.
