Its advantages include simple structure, high damping effect, low cost and long service life.
Description
One, technical field
The present invention relates to a kind of shock absorber, the magnetically floating vibration damper that uses on particularly a kind of motor bike and the battery-driven car.
Two, background technology
Along with the progress of society, the improvement of living standard, shock absorber has also obtained using widely as appurtenances, and the fast development of the shock absorber that motor bike and battery-driven car use is exactly good example.The shock absorber that the present shock absorber that uses generally adopts hydraulic pressure and mechanical vibration damping to combine, a kind of shock absorber as Chinese patent 98204937.4, clutch release slave cylinder is housed in urceolus, piston rod passes oil sealing and orienting sleeve and enters in the clutch release slave cylinder and link to each other with piston, is provided with the damping oil groove in the middle part of the clutch release slave cylinder, and the bottom is provided with bottom valve, bottom valve is provided with compensation channels and damping hole, piston is provided with the piston damping hole, is provided with check valve on oil storage chamber top, and the bottom is provided with the bubble baffling device.Though this scheme stable performance, traveling comfort are good, it is big to exist complex structure, accuracy requirement height, difficulty of processing, secondly is that mechanical wear is big, easy oil leakage, besides disadvantage such as the undesirable and cost height of damping effect.
Three, summary of the invention
For overcoming the disadvantage of above-mentioned existence, problem to be solved by this invention provides a kind of both simple in structure, easy to process, again good damping result, wearing and tearing little and need not with oil shock absorber.The technical solution used in the present invention is that the principle of work according to permeability magnetic material " same sex is repelled each other, and there is a natural attraction between the sexes " realizes; Its scheme is as follows: the capping that has centre hole is fixed on the damper cylinder, buffer beam passes the capping centre hole and stretches out damper cylinder, the damper cylinder upper magnetic steel that fixedly has centre hole suitable for reading, the tube end, is lower magnetic steel fixedly, moving magnet steel is fixed on the buffer beam, and is arranged between the upper and lower magnet steel, is provided with the buffering magnet steel of the activity that is enclosed within on the buffer beam between upper magnetic steel and moving magnet steel, be provided with the suspension magnet steel in the tube between moving magnet steel and lower magnetic steel, the identical setting of magnetic between the interior set adjacent magnet steel of tube.The present invention adopts said structure, has not only solved the problem of complex structure, processing difficulties, and need not with oil; And have rational in infrastructure, good damping effect, mechanical wear little, produce characteristics such as adult is low, the life-span is long.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of second kind of embodiment of the present invention.
Fig. 3 is the structural representation of the third embodiment of the present invention.
Five, the specific embodiment
Shown in Figure 1, the embodiment of first kind of magnetically floating vibration damper of the present invention, it comprises buffer beam 1, damper cylinder 11 and capping 3, the capping 3 that has centre hole is fixed on the damper cylinder 11, buffer beam 1 passes capping 3 centre holes and stretches out damper cylinder 11, capping 3 is provided with sealing lining ring 2, prevents that dust from entering in the damper cylinder 11; Damper cylinder 11 upper magnetic steels 4 that fixedly have centre hole suitable for reading, the tube end, is lower magnetic steel 10 fixedly, and moving magnet steel 7 is fixed on the buffer beam 1, and is arranged between the upper and lower magnet steel 4,10; Between upper magnetic steel 4 and moving magnet steel 7, be provided with the buffering magnet steel 5 of the activity that is enclosed within on the buffer beam 1; Be provided with suspension magnet steel 8 in the tube between moving magnet steel 7 and lower magnetic steel 10; The identical setting of magnetic between the interior set adjacent magnet steel of tube.When magnetically floating vibration damper bears downward application force, buffer beam 1 drives moving magnet steel 7 and moves downward, under the effect in magnetic field, suspension magnet steel 8 and lower magnetic steel 10 produce one thrust that makes progress, stop buffer beam 1 and moving magnet steel to move downward, when downward force was equal with upward force, buffer beam 1 and moving magnet steel 7 just stopped to move downward; Because force of inertia fades away, the thrust that magnetic field produces is greater than downward application force, buffer beam 1 drives magnet steel 7 again and up moves, upper magnetic steel 4 and buffering magnet steel 5 produce downward thrust, stop buffer beam 1 and moving magnet steel upward movement,, producing balance up to two strands of application forces up and down, buffer beam 1 and moving magnet steel 7 stop up to move; Because the disappearance of force of inertia produces a downward magnetic field thrust again, so repeatedly, reach balance again, buffer beam 1 and the 7 just stop motions of moving magnet steel up to power downward and that make progress.Thereby realize the purpose of the floating vibration damping of magnetic.In order to regulate effectiveness in vibration suppression, can regulate up and down propelling thrust by the piece number that adopts ferromagnetic material, adjusts mutual cooresponding face area and set up buffering magnet steel 5 and suspension magnet steel.Because leakage field damper cylinder 11 outside faces produce magnetic,, be provided with leakproof magnetosphere 6 in order to solve at the outside face of magnet steel easily with the disadvantage of absorption such as iron filings and iron wire on it.
Shown in Figure 2, for second kind of magnetically floating vibration damper of the present invention, comprise buffer beam 1, damper cylinder 11 and capping 3, the capping 3 that has centre hole is fixed on the damper cylinder 11, buffer beam 1 passes capping 3 centre holes and stretches out damper cylinder 11, and capping 3 is provided with sealing lining ring 2, prevents that dust from entering in the damper cylinder 11; Damper cylinder 11 upper magnetic steels 4 that fixedly have centre hole suitable for reading, the tube end, is lower magnetic steel 10 fixedly, and the middle part is provided with the middle magnet steel 12 of band centre hole; Moving magnet steel 7 is movably arranged between middle magnet steel 12 and the lower magnetic steel 10, and captives joint with buffer beam 1; On the buffer beam 1 between upper magnetic steel 4 and the middle magnet steel 12, be fixed with moving magnet steel 9, the identical setting of magnetic between the interior set adjacent magnet steel of tube; Outside face at magnet steel is provided with leakproof magnetosphere 6.The principle of work of present embodiment and first kind of embodiment are basic identical, no longer repeat at this.
Shown in Figure 3, be the third magnetically floating vibration damper of the present invention, comprise buffer beam 1, damper cylinder 11 and capping 3, the capping 3 that has centre hole is fixed on the damper cylinder 11, buffer beam 1 passes capping 3 centre holes and stretches out damper cylinder 11, and capping 3 is provided with sealing lining ring 2, prevents that dust from entering in the damper cylinder 11; Damper cylinder 11 bottoms are fixed with lower magnetic steel 10, what the tube internal fixation had a band guide hole 13 decides magnetic pole 14, be provided with moving magnetic pole 15 with matching in the guide hole 13, moving magnetic pole 15 is captiveed joint with buffer beam 1, it is opposite with moving magnetic pole 15 polarity to decide magnetic pole 14, moving magnetic pole 15 cooresponding lower magnetic steels 10 and the identical setting of moving magnetic pole 15 magnetic; Outside face at magnet steel 10 is provided with leakproof magnetosphere 6.Present embodiment according to moving magnetic pole 15 with decide magnetic pole 14 there is a natural attraction between the sexes to realize reaching goal of the invention of the present invention equally by vibration damping.
