Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorbing regulator. Background Art
[0002] Shock absorbers play a vital role in vehicles and mechanical equipment, absorbing and reducing shocks: When vehicles or mechanical equipment pass through uneven roads or are subjected to external impacts, shock absorbers can quickly absorb and reduce the resulting vibrations and bumps, which not only helps to protect the various components of the vehicle and equipment and reduce the damage that may be caused by the impact, but also improves ride comfort and stability. In the vehicle suspension system, shock absorbers work with springs. After the spring absorbs the impact of the road and compresses, the shock absorber can suppress the rapid rebound of the spring when the energy is released, so that the vehicle body returns to the normal driving state more smoothly and improves the ride smoothness: By effectively absorbing and reducing vibrations, shock absorbers can significantly improve the vehicle's ride smoothness and make the driving experience more comfortable. At the same time, this also helps to reduce the discomfort or damage that may be caused to passengers and cargo due to vibrations;
[0003] When facing different working environments, existing shock absorbers all adjust the length by squeezing the spring in the shock absorber. It is impossible to adjust the length without squeezing the spring. The different lengths of the springs in the shock absorber also reflect their different functional requirements. Longer springs are suitable for driving on bumpy roads because they can absorb and disperse impacts, while shorter springs may be more suitable for driving on smooth roads because they can provide direct and sensitive control feedback.
