Abstract
The utility model relates to an electromagnetic shock absorber comprising an upper barrel and a lower barrel, one end of the upper barrel is arranged in the lower barrel, the upper barrel and the lower barrel are matched in a sliding way, a shock absorption pole is arranged in the upper barrel, a movable shaft is arranged in the lower barrel, a first permanent magnet is arranged at the lower end of the shock absorption pole, a second permanent magnet is arranged at the upper end of the movable shaft, S poles of the first permanent magnet and the second permanent magnet are arranged oppositely, a first coil is arranged on the shock absorption pole, a second coil is arranged on the movable shaft, and the first coil and the second coil are connected with an external power supply respectively. The first coil and the second coil can generate magnetic field movement, the repelling force of like charges of the permanent magnets is enhanced, the shock of a vehicle is reduced, so as to achieve the purpose of adjusting the magnitude of the magnetic force, and better protect the safety of the vehicle and objects in the vehicle and the traveling quality.
Description
Technical field
The utility model relates to a kind of vehicle shock absorber, is specifically related to a kind of electromagnetic shock absorber.
Background technique
At present, vibration damper has hydraulic type, spring, electromagnetic type several types, and the Sealing of hydraulic type is aging easily, easily causes leakage of oil and environmental pollution problem; Spring is to utilize the restorable ability of object, and this mode is easy to generate fatigue, fracture in frequent deformation repeatedly; Electromagnetic type is used the resulting magnetic suspension of two same pole generation repulsive forces and is reached good vibration isolation.But because the gap of vehicle-mounted load and road quality is big, same electromagnetism damping can not be protected the safety of vehicle and vehicle-mounted thing and the quality of travelling better.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of electromagnetic shock absorber, and it can adjust the magnetic force size when vehicle-mounted load and road quality are different, guarantee the safety of vehicle and vehicle-mounted thing and the quality of travelling.
The technological scheme that realizes the utility model purpose is as follows:
A kind of electromagnetic shock absorber, comprise upper cylinder, lower cylinder body, one end of upper cylinder is arranged in the lower cylinder body, upper cylinder and lower cylinder body are slidingly matched, be provided with decoupling rod in the upper cylinder, be provided with movable axis in the lower cylinder body, the lower end of decoupling rod is provided with first permanent magnet, the upper end of movable axis is provided with second permanent magnet, first permanent magnet, second permanent magnet are that the S utmost point same sex is oppositely arranged, described decoupling rod is provided with first coil, and movable axis is provided with second coil, and first coil, second coil are connected with the power supply of outside respectively.
Described decoupling rod, movable axis are threaded in respectively on upper cylinder, the lower cylinder body.
Adopt such scheme, decoupling rod is loaded with when weighing, and upper cylinder is pressed into lower cylinder body, be installed in the permanent magnet in the upper and lower cylindrical shell respectively, under the effect that the same sex is repelled each other, overcome wheel in spring that travels down produced, make it keep the suspension balance, reduce the vibrations of vehicle.Under the situation poor at road, that load is light; when spring strengthens; the enable switch energising; first coil, second coil produce Movement in Magnetic Field; increase the permanent magnet same sex dynamics of repelling each other; make vehicle reduce vibrations, reach the purpose that to adjust the magnetic force size, protect the safety of vehicle and vehicle-mounted thing and the quality of travelling better.
