Description
Technical field
The utility model relates to a kind of rail vehicle secondary suspension devices, fill more particularly, to a kind of magnetic suspension secondary suspension
It sets.
Background technique
What the secondary suspension of traditional locomotive, passenger train, subway and tramcar etc. used be all steel spring or
Flat spring, the difference of the secondary suspension device of modern rolling stock according to demand can use steel spring, rubber metal pad or air bullet
Spring etc..The contacts secondary suspension mode such as steel spring or rubber metal pad, rigidity is bigger, and the comfort of vehicle is poor, while not
Have active regulating power, the height of vehicle can not be controlled.
Air spring can fill wind pressure according to the empty spring of the load of vehicle adjustment, so as to adjust the rigid of secondary suspension
Degree, while the height of adjustable car body, but sky spring is solely subjected to pressure, so needing increase anti-to resist the movement of sidewindering of car body
Side rolling torsion rod device, while in order to which the vertical damping that decays needs to increase air inlet restriction hole or vertical damper.With the appearance of space-time spring
Product not enough needs to increase auxiliary air reservoir to meet performance requirement, so needing multiple components collaborations to reach the performance of sky spring
Work, structure is complicated, and weight is larger.Its stiffness and damping etc. is all fixed numbers simultaneously, can not achieve real-time adjustment.
Utility model content
The purpose of this utility model is that the comfort and stationarity of rolling stock are improved using maglev superior function,
Solve the problems such as existing structure is complicated, and weight is larger.
To achieve the above object, the utility model provides a kind of magnetic suspension secondary suspension device, it is characterised in that: including upper
Suspension magnetic pole and lower suspension magnetic pole, the magnetic pole that upper suspension magnetic pole is made of multiple pole coils, to generate vertical and transverse direction side
To changing magnetic field, lower suspension magnetic pole is fixed magnetic pole, generates the magnetic field of fixed-direction, and upper suspension magnetic pole and lower suspension magnetic pole exist
Plane and plane cooperation on vertical, as vertical backstop, upper suspension magnetic pole and lower suspension magnetic pole be horizontally arc surface and
Arc surface cooperation, as lateral backstop.
The upper suspension magnetic pole cooperation position is two-stage evagination circular arc, and two-stage circular arc is concentric circles, lower part arc radius
Greater than middle part arc radius；The lower suspension magnetic pole cooperation position is concave arc in two-stage, and two-stage circular arc is also concentric circles, on
Portion's arc radius is less than middle part arc radius.
There is orienting roll pilot trench in plane on lower suspension magnetic pole, guide roller is installed, guide roller is in magnetcisuspension in roller slot
When floating device is without electricity, upper and lower magnetic pole contact generates relative motion, sliding friction is avoided, to reduce steering resistance.
The utility model has the advantage that and improves compared with prior art:
1, it is automatically controlled relative to gas control reaction speed faster, it is higher to the control sensitivity of vehicle.
2, level of integrated system is high, occupies little space, light-weight convenient for assembling and maintenance.
3, to be contactless when working, the damage of friction can be reduced.
4, using metal structure and coil, ageing resistance is better than rubber, has longer service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is upper suspension magnetic pole schematic diagram；
Fig. 3 is lower suspension magnetic pole schematic diagram.
Wherein: guide roller 1, upper suspension magnetic pole 2, lower suspension magnetic pole 3, upper suspension magnetic pole lower plane 4, outside upper suspension magnetic pole
Convex middle part arc surface 5, upper suspension magnetic pole evagination lower part arc surface 6, plane 7, lower suspension magnetic pole indent top on lower suspension magnetic pole
Arc surface 9 in the middle part of arc surface 8, lower suspension magnetic pole indent.
Specific embodiment
Referring to Fig.1, specific embodiment of the present invention includes upper suspension magnetic pole 2, lower suspension magnetic pole 3, upper suspension magnetic pole 2
Vertical and lateral electromagnetic force is generated by electric signal with lower suspension magnetic pole 3.Upper suspension magnetic pole 2 is internally integrated multiple pole lines
Circle can generate vertical and transverse variable magnetic field according to control signal, and lower suspension magnetic pole 3 is fixed magnetic pole, generate fixation side
To magnetic field, using the heteropolar attracting principle of upper and lower magnetic field homopolar-repulsion, generate corresponding vertical force and cross force repulsion and
Suction is furnished with two pairs of suspension magnetic poles to realize that car body is suspended in above bogie on each bogie, two to magnetic pole when work
It acts on simultaneously.When movement is sidewindered in the excessively curved car body generation of vehicle, thus it is possible to vary the magnetic force of side magnetic pole is the side of suction and car body
Dynamic balance is rolled, so that inhibit car body sidewinders movement.There is orienting roll pilot trench in plane on lower suspension magnetic pole, is equipped in roller slot
Guide roller 1, guide roller are used for when magnetic levitation system is without electricity, and upper and lower magnetic pole contact generates relative motion and sliding is avoided to rub
It wipes, to reduce steering resistance.
Referring to Fig. 2 and Fig. 3, upper suspension magnetic pole cooperation position is two-stage evagination circular arc 5,6, and two-stage circular arc is concentric circles, under
Portion's circular arc radius surface is greater than middle part circular arc radius surface, and then forms lower edge.Lower suspension magnetic pole cooperation position is concave arc in two-stage,
Two-stage circular arc is also concentric circles, and the radius of top arc surface 8 is less than the radius of middle part arc surface 9, and then forms upper edge.It is outstanding up and down
Floating magnetic pole is that plane 7 cooperates on upper suspension magnetic pole lower plane 4 and lower suspension magnetic pole on vertical, is horizontally upper suspension magnetic pole
Arc surface 5 and lower suspension magnetic pole indent top arc surface 8 cooperate in the middle part of evagination, upper and lower pole assemblage to the center of circle of rear circular arc together
It is identical, guarantee that two suspension magnetic poles can be relatively rotated around the common center of circle, for meeting bogie around car body rotary motion
It is required that.Lateral circular arc mating surface magnetic pole provides lateral repulsion and controls transverse movement, while the extreme position of limit lateral movement,
Play the role of lateral backstop.It is plane and plane cooperation on vertical, as vertical backstop.
