Summary of the invention
By above-mentioned prior art, the task of the present present invention is, it is provided that a kind of fluid power subtracts
Speed device, wherein it is possible between blade arrangement and the blade arrangement of stator by change rotor
Axial spacing changes braking moment, but can realize the bust of braking power simultaneously.
The feature that this task combines its characteristic from the preamble of claim 1 is able to
Solve.What follow-up appurtenance required to provide respectively the present invention is advantageously improved scheme.
According to the present invention, hydraulic retarder includes stator and rotor, and they are in side facing with each other
On be respectively provided with each blade arrangement and fluid can be introduced between which.Additionally, turn
Son couple with armature spindle and at this in the way of the axially opposed stator of energy moves at this armature spindle
Upper guiding, thus the spacing of the blade arrangement of the blade arrangement of stator and rotor can change.
Additionally, be provided with following mechanism, by this mechanism, rotor can be transplanted on the position away from stator
In.
The running under braking of the hydraulic retarder according to the present invention is with in principle in those skilled in the art
Known ways and means realize as follows, i.e. introduce especially between rotor and stator
Form is oil or the fluid of water, and the blade arrangement of the rotor that this fluid then passes through rotation is driven
Get up and be transported the direction of blade arrangement to stator, there fluid be supported and
The most again flow back to the blade arrangement of rotor.This causes rotor slow down and therefore cause at rotor
On corresponding braking moment.The size of this braking moment relies currently on the blade arrangement of rotor
And the axial spacing between the blade arrangement of stator, wherein, occupies the position away from stator at rotor
When putting, the fluid by introducing produces minimum braking moment, and occupies near stator at rotor
Position time produce maximum braking moment by the fluid introduced.
Here, change braking moment principle by changing the axial spacing between rotor and stator
On have the advantage that, i.e. in order to running under braking fixing Fluid Volume can be incorporated into turn
Brake force is performed in the working chamber of bound and subsequently according only to axial spacing between son and stator
Square regulates.Big Fluid Volume reduces air pocket formability and can realize the high of decelerator
Thermal heat transfer capability, because can also absorb a lot by big Fluid Volume during running under braking
Heat.And be purely braked in the decelerator of torque adjusting via the change of Fluid Volume wherein,
The braking power wanting to realize abundance it is necessary under the lowest rotor speed.But, this also leads
Cause rise along with the rotating speed of rotor and especially must reduce Fluid Volume under the highest rotating speed, with
Just braking power is limited., the minimizing of Fluid Volume also causes the fluid introduced in running under braking
Period heats up more quickly.Accordingly, because the maximum allowable temperature of fluid strictly limits
The braking power allowed.
The present invention includes that following technology is instructed now, i.e. can be transplanted on rotor away from stator
Rotor is coupled by the mechanism of position with armature spindle circumferentially direction, and additionally, will be by introducing
Fluid and on rotor produce braking moment be converted into along to the position from stator direction act on
Axial force.In other words, the mechanism between rotor and armature spindle is on the one hand for by two groups
Part couples, and on the other hand the braking moment on rotor is converted into along deviating from stator sensing
Direction effect axial force.
Here, such design of decelerator has the advantage that, i.e. as long as at rotor
On cause braking moment, rotor to be no need for other counter measure and be automatically moved into away from fixed
The position of son.For this respect, in addition to the running under braking of decelerator, it is not necessary to use
This control is driven away from lasting on the position of stator to be maintained at by rotor.As long as no to by
Fluid in the chamber being incorporated between stator and rotor carries out back action, and this fluid is the most logical
Crossing mechanism causes rotor displacement to arrive the position away from stator efficiently.Additionally, thus subtracted by fluid power
The braking moment that speed device produces can quickly reduce, this is because be positioned at rotor in running under braking
And the fluid between stator contributes to dividing each other of the blade arrangement of stator and the blade arrangement of rotor

Rotor motion is caused to arrive between blade arrangement the most in opposite direction, i.e. near the position of stator.
This result on the one hand caused is, in addition to running under braking, to apply certain axial all the time
Power, in order to rotor by less desirable, cause due to idling loss in the way of be moved adjacent to fixed
The position of son carries out back action.Additionally, the bust of braking moment here cannot be produced, this
It is because it is first necessary to overcome the fluid by being still located in working chamber produces, Xiang Ding on one's own initiative

Fig. 1 shows the liquid corresponding to a preferred embodiment of the present invention being in idle running
The view of the cross-section of power decelerator；And
Fig. 2 shows another cross sectional view of the decelerator of the Fig. 1 being in running under braking.
Detailed description of the invention
Fig. 1 illustrates the hydraulic retarder 1 according to a preferred embodiment of the present invention.This subtracts
Speed device is made up of stator 2 and rotor 3 at this, and their side facing with each other is equipped with leaf respectively
Sheet assortment 4 or 5, and the working chamber 6 of stator and rotor bound anchor ring shape between which.
Rotor 3 is now arranged on armature spindle 7, and in addition to rotor 3, this armature spindle also draws

In the case of on armature spindle 7 when running under braking deceleration due to rotor 3 can cause that
Sample.It is to say, the braking moment caused on rotor 3 by fluid is by taking teeth portion 12
The increasing of spacing x it is converted in the case of achieving the rotor 3 relative motion with armature spindle 7
Greatly.
Here, this move automatically produce and this move can be in the braking of hydraulic retarder 1
Importing rapidly due to the braking moment that causes on rotor 3 under operation, this also directly results in system
The reduction of kinetic moment.Rotor 3 occupies the position away from stator shown in Fig. 1 subsequently as finally
Position, on this position, spacing x is selected such that in the case of emptying working chamber more than 6
Not via blade arrangement 4 and 5 pumped air, and hydraulic retarder 1 for this respect
Loss power can be kept as the least.
Automatically carry out owing to rotor 3 to be transplanted on the position away from stator, it is necessary to lead on one's own initiative
Overregulate mechanism 13 to realize the rotor 3 motion to the direction of stator 2.Governor motion 13 exists
This is realized by the piston 14 structural scheme on the side of rotor 3, and this piston is at housing 15
Middle extension and jointly surround pressure chamber 16 with housing 15.This pressure chamber 16 can have pin subsequently
To property ground Loading Control pressure, thus produce the axial force to the effect of the direction of stator 2.
From overcome in opposite direction, by braking moment by taking the axle that teeth portion 12 produces
Xiang Liqi, rotor 3 subsequently on armature spindle 7 spacing x reduce in the case of towards stator 2
Motion.Here, rotor can occupy figure in the case of pressure chamber 16 is with corresponding pressure-loaded
The position of the close stator shown in 2 as final position, occupy under this position the least between
Away from x.If but the pressure in pressure chamber 16 reduces again, then enter by taking teeth portion 12
Row rotor 3 is to away from the automatic transfer mentioned in the position of stator.
As be can be additionally seen by Fig. 2, pressure chamber 16 and working chamber 6 via at least one
The throttle orifice 17 extended in rotor 3 is connected to each other.Fluid at this from pressure chamber 16 via this
Throttle orifice 17 flows out in working chamber 6, this simplify and enters the control pressure in pressure chamber 16
The regulation of row, is maintained by fluid replacement at least as respective desired control pressure.?
In the range of pressure chamber 16, it is additionally provided with (being not shown here) sensor, via this sensing
