Detailed description of the invention
Shown in the drawings of the Advantageous embodiments of the invention being described below.Wherein:
Fig. 1 shows the part of the hydraulic retarder corresponding to a preferred embodiment of the present invention in idle running
The view splitted；And
Fig. 2 shows another section views of the retarder of Fig. 1 in running under braking.
Specific embodiment
Fig. 1 shows the hydraulic retarder 1 of a preferred embodiment according to the present invention.The retarder is herein by stator 2
It is constituted with rotor 3, their side facing with each other has been separately equipped with blade arrangement 4 or 5, and stator and rotor are between them
The working chamber 6 of bound anchor ring shape.
Rotor 3 is now arranged on armature spindle 7, and other than rotor 3, which also guides roller gear 8, in fluid power
In the state that retarder 1 has been mounted in the driving system of motor vehicle, armature spindle 7 in its rotational motion via the roller gear with
Axial parallel axis connection.In addition, be additionally provided with supporting arrangement 9 and 10 in the axial sides of roller gear 8, armature spindle 7 with
The mode being able to rotate is supported via these supporting arrangements.
In addition, rotor 3 is via form as can see in the other sectional view in Fig. 1 and in Fig. 2
The mechanism 11 of taking teeth portion 12 couples with armature spindle 7, which helically extends and by rotor 3 and armature spindle 7
Monodentate portion constitute.Here, taking teeth portion 12 similar to lead screw gear constructs and rotor 3 is opposite with armature spindle 7
It is converted into axial movement of the rotor 3 on armature spindle 7, and the feelings in the axial position that rotor 3 is fixed on armature spindle 7
Under condition, (drehfest) for realizing the anti-relative rotation between rotor 3 and armature spindle 7 couples.
Hydraulic retarder 1 can connect inside driving system to be used as main reducing gear before vehicle transmission or can connect
As secondary retarder after vehicle transmission.In both cases, it armature spindle 7 and is occupied on armature spindle 7 in turn
Rotor 3 when fixed axial position is all driven by roller gear 8.In addition, especially form is liquid, such as oil or water
Fluid be introduced in working chamber 6, the liquid therefore pass through rotation rotor 3 blade arrangement 5 be driven and to
The direction of the blade arrangement 4 of stator 2 is transported, and liquid is supported and then leads back to blade arrangement 5 again there.This is corresponding
Ground causes rotor to slow down and generates braking moment on rotor, in the case where connection, is somebody's turn to do with the anti-relative rotation of armature spindle 7
Braking moment is imported in driving system by roller gear 8 in a manner of accordingly rotating.
Here, the size of the braking moment generated by hydraulic retarder 1 on the one hand can by introduced Fluid Volume come
It adjusts, and on the other hand can be adjusted by adjusting axial spacing x between blade arrangement 4 and 5.Here, not only being drawn
The Fluid Volume entered, and spacing x can infinitely change, so as to be realized on armature spindle 7 by the two governing loops
Different braking moments.It is particularly preferred that hydraulic retarder 1 is run as far as possible with filling the state of fluid, because
Air pocket formability is on the one hand reduced for high Fluid Volume and higher heat absorption and in turn more on the other hand may be implemented
Prolonged running under braking.
It is particular in that, taking teeth portion 12 walks to be constructed such that upwards the lag of 3 relative rotor axis 7 of rotor at it
(Nachlaufen) axial movement of the rotor 3 on armature spindle 7 to the direction for increasing spacing x, the lag are forcibly converted into
Just as the deceleration in the case where rotor 3 is not axially fixed on armature spindle 7 in running under braking due to rotor 3 can be led
As cause.Rotor 3 is being realized that is, passing through fluid caused braking moment on rotor 3 and passing through taking teeth portion 12
The increase of spacing x is converted in the case where relative motion with armature spindle 7.
Here, the movement is automatically generated and the movement can be under the running under braking of hydraulic retarder 1 due to turning
Son 3 on caused braking moment and import rapidly, this also directly results in the reduction of braking moment.Rotor 3 then occupies shown in Fig. 1
Separate stator position as final position, on the position, spacing x is selected such that the case where emptying working chamber 6
Under hardly via the pumped air of blade arrangement 4 and 5, and the loss power of hydraulic retarder 1 can be protected for this respect
Hold very small.
It is automatically carried out since rotor 3 is transplanted on the position far from stator, it is necessary to actively by regulating mechanism 13
Realize movement of the rotor 3 to the direction of stator 2.Regulating mechanism 13 passes through construction side of the piston 14 on the end side of rotor 3 herein
Case realizes that the piston extends in shell 15 and surround pressure chamber 16 jointly with shell 15.The pressure chamber 16 then can be with
Targetedly load control pressure, to generate the axial force acted on to the direction of stator 2.
From overcoming axial force that is contrary, generating by braking moment by taking teeth portion 12, rotor 3 with
Afterwards on armature spindle 7 spacing x reduce in the case where towards stator 2 move.Here, rotor can be in pressure chamber 16 with corresponding
The position of close stator shown in Fig. 2 is occupied in the case where pressure-loaded as final position, is occupied as far as possible down in the position
Small spacing x.However if the pressure in pressure chamber 16 reduces again, arrived by the progress rotor 3 of taking teeth portion 12 separate
The automatic transfer mentioned in the position of stator.
Such as the section that as also can be seen Fig. 2, pressure chamber 16 and working chamber 6 extend in rotor 3 via at least one
Discharge orifice 17 is connected to each other.Fluid flows out in working chamber 6 from pressure chamber 16 via the throttle orifice 17 at this, and this simplifies to pressure
The adjusting that control pressure in power chamber 16 carries out is maintained at least because of respective desired control pressure by fluid replacement.
In the range of pressure chamber 16, it is additionally provided with (not shown here) sensor, via in sensor detection pressure chamber 16
Current pressure.
The axial force that axial position of the rotor 3 on armature spindle 7 is generated accordingly by one side via taking teeth portion 12
Relationship relative to the axial force realized via pressure chamber 16 is adjusted.If the axial force of two phase opposite senses is supported each other
It repays, then rotor 3 is just placed on armature spindle 7 in anti-relative rotation.And if axial force is different, this is converted into spacing x
Corresponding change.
Finally, being additionally provided with spring element between rotor 3 and stator 2 as also can be seen in fig. 1 and 2
18, rotor 3 is pre-tightened via the spring element to the direction of the position far from stator.Thus it is ensured that stopping of the rotor 3 in system
Always the position far from stator is occupied under state, and therefore will not be provided with the idle capacity of hydraulic retarder 1 at the start
So big braking moment.
By the design scheme according to the present invention of hydraulic retarder, especially may be implemented during emergency braking quickly
Eliminate braking moment.
