Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of not making the creative labor
Embodiment shall fall within the protection scope of the present invention.
The technology proposed provides high degree of adaptability and reliable mechanical connection/disconnection system, can serve as various
Coupling/uncoupling mechanism between fixed or rotary body/system.Group of the technology based on magnetic coupling and highly intuitive sliding system
It closes.The disconnection system proposed is integral type solution, can be easily integrated in rotation (or even static) vehicle body it
Between, but regardless of between its both sides connected to it power and torque have any mismatch.
The disconnection device proposed is as shown in Figure 1, the simple gracefulness of the system proposed in it can easily observe.
As an example, disconnection system here is depicted as being implemented into generating set application, is located at generator and prime mover
Between (such as turbine).
Operating concept Fig. 2 a) indicate that system is in its engagement state, i.e., when system is in normal operating.In such case
Under (i.e. input shaft and output shaft rotates together), there is no the electrically or mechanically transmissions of power or torque.Linear actuators coil is not
It powers (closing power supply).Turn and wheel hub are magnetic-coupled.Due to not needing electric power or machine power in this case,
System is actually lossless, and due to assembly permanent magnet (PM), and turn is maintained at suitable by the magnetic locking device of wheel hub
When position.Fig. 2 b) show discrete state.When detachment is desired, linear actuators coil is by direct current (DC) pulse power supply.Its
Magnetic field and magnetic field (on turn) will produce required thrust when interacting, to detach wheel hub magnetic padlock mechanism and by turn
Son pulls to stator magnet latch mechanism.When turn is when advancing, PM by modified alignment, to generate coupling strength from
Dynamic adjustment (reducing in this case).Once turn reaches stator, the DC pulse of coil is closed, and it is fixed that turn passes through
Sub- magnetic padlock mechanism is held in position in.
Magnetic coupling mechanism Basic Couplings system is a kind of multipole magnetic coupling, as shown in figure 3, it indicate immediately one it is automatic same
Step system.There is no mechanical couplings between surface of revolution, this is very favorable for the reliability in disconnection system itself.In order to
Decoupling, required to be only simply directed at two PM storehouses, such as Fig. 2 b) shown in.Accomplish this point, it is only necessary to a direct current
Pulse drives the turn sub.This can be simply implemented by using DC power supply.
Itd is proposed systematic difference it is this it is novel/be highly suitable for and be reliably mechanically connected/disconnection system be it is a kind of easily
In the monomer solution of installation, the old of safe coupling/uncoupling between two or more mechanisms can be solved the problems, such as.It can be quick
Efficiently separate rotation or static object.Connect/disconnect the technology itself that the movement needed for action is included in the present invention
It is interior, therefore any pre-existing hardware need not all be changed.Such technology is in such as mobile applications such as aviation/automobile
In pursued very much, wherein various systems need with error protection disconnect system, to ensure in any component malfunction
In the case of vehicle safety.The advantages of proposal system is with the relevant most significant advantage of this technology：
One super simple and graceful system, it is only necessary to several components, wherein most of components are all passive blocks.From
Mechanical angle sees that bill of materials (BoM) is only limitted to two bearings, four PM heaps and a coil.
Very limited control/electric component, when detachment is desired, it is only necessary to of short duration DC current pulse.This can be with
It is realized by a baby battery or enough capacitance, is controlled by a simple electronic switch.
The efficiency of normal operation system nearly reaches 100%, because all not having in any time point during normal operation
Electric power or mechanical transfer electric power.
It is totally independent of the fully automated synchronization system of system speed.It does not need any external sync and calculates and/or same
Step system has very high torque transmittability because magnetic coupling will ' enjoy ' sizable transmission amplification, such as it is traditional
" machinery " gear-box.
Include any linear movement in the system of the present invention, this is eliminated to any line on generator and/or turbine wheel shaft
Property be axially moved needs.If there are other failures in system, natural safe slippage torque will produce.
Described above to be merely exemplary for the purpose of the present invention, and not restrictive, those of ordinary skill in the art understand,
In the case where not departing from spirit and scope defined by claims appended below, many modifications, variation or equivalent can be made,
But it falls in protection scope of the present invention.
