Abstract
The invention relates to a buffering device and particularly relates to a permanent magnet buffer for vehicle damping. The buffer is mainly composed of a spindle, a guide sleeve, magnetic yokes, permanent magnets, a cylinder, oil film, a piston and a nut. The permanent magnets are arranged between the two magnetic yokes successively, and polarities of the permanent magnets and the adjacent permanent magnets are identical. According to the buffer, a magnetic field theory is used, the buffer is designed by using an eddy principle, magnetic poles with the same polarities repel mutually to generate repelling force, the acting force of the magnetic field on the eddy prevents the displacement of the spindle, and accordingly, vehicle body damping is achieved. Compared with the prior product, the permanent magnet buffer has the advantages of being convenient to use, simple in structure, low in cost, small in anti-abrasion and anti-friction coefficient, low in noise and capable of improving the product working stability and prolonging the service life.
Description
Technical field
The present invention has designed a kind of damping device, and particularly a kind of permanent magnetism buffer, for vehicle damping aspect.
Background technique
The buffer using in the market, generally adopts spring or rubber shock-absorbing, yielding or aged deterioration for a long time for spring and rubber, and volume is thick, send the sound when concussion, therefore buffer is restricted working life.Or use hydraulic damping device by cylinder body, at the built-in piston matching of cylinder body, the damping hole that cylinder body two cavity oil liquid is communicated with is set on piston.Can automatically regulate the pressure reduction of cylinder body two cavity oil liquid to realize vehicle body damping by the damping hole on piston.But because the accuracy of manufacturing of this damping device is high, therefore, cost is high; Sealing easily damages, and exists oil leaking pollution environment, reduces damping effect, and working life is low etc.
Summary of the invention
The object of the invention is to make up above-mentioned deficiency, a kind of permanent magnetism buffer is provided, improve working life, reduce costs, the pollution that can avoid leakage of oil to produce environment.
Technological scheme of the present invention is: it comprises cylindrical shell, on the main shaft of installing in cylindrical shell, has many magnetic strategic points to breathe out and magnet, and permanent magnet is sequentially arranged between two magnetic strategic points in order, and permanent magnet is identical with the polarity of adjacent permanent magnet.The guide sleeve matching is set on cylindrical shell, main shaft.Adopt magnetic field theory, utilize vortex principle design, between this device main shaft and cylindrical shell, there is stable magnetic field, in the time that vehicle body shakes, between the main shaft being connected with vehicle frame and cylindrical shell, just have relative movement, the magnetic field that the water magnet being connected with main shaft produces makes to change rapidly by the magnetic flux of cylindrical shell, on cylindrical shell, produce eddy current, the magnetic pole of the same sex produces phase repulsive interaction like this, produces repulsive force, magnetic field hinders the displacement of main shaft to the active force of this eddy current, thereby realizes vehicle body damping.
Compared with existing product, permanent magnetism buffer not only easy to use, simple in structure, cost is low, has the features such as wear-resisting, friction factor is little, noise is low, has improved the working stability of this product, has extended working life.

specific implementation method
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, the present invention is mainly made up of main shaft 1, guide sleeve 2, magnetic strategic point 3, permanent magnet 4, cylindrical shell 5, oil film 6, piston 7, nut 8.Permanent magnet 4 is placed between two magnetic strategic points 3 successively, and permanent magnet 4 is identical with the polarity of adjacent permanent magnet 4.Magnetic strategic point 3 adopts the materials such as electrical pure iron, silicon steel plate to make, and the best rare earth that adopts of permanent magnet 4 is made.When vehicle, to run in the process of moving road surface high and low not at ordinary times, between the main shaft being connected with vehicle frame and cylindrical shell, just there is relative movement, the magnetic field that the water magnet being connected with main shaft produces makes to change rapidly by the magnetic flux of cylindrical shell, on cylindrical shell, produce eddy current, the magnetic pole of the same sex produces phase repulsive interaction like this, produce repulsive force, magnetic field hinders the displacement of main shaft to the active force of this eddy current, thereby realizes vehicle body damping.
