Rotating element on and so that rotating element brake.
The invention further relates to a kind of hydraulic power units with corresponding rotor brake device, wherein gear unit
With fluid clutch and/or fluid torque-converter and at least one mechanical gear stage.
The present invention also relates to a kind of methods for controlling this gear unit.
Background technique
Such as 4226665 A1 of patent document DE disclose a kind of hydraulic power unit with rotor brake device and
A kind of corresponding rotor brake device.It is shown in document with fluid clutch, fluid torque-converter and multiple mechanical transmissions
The hydraulic transmission system of grade, especially as as rail transit tool.It is transmitted by the rotation of main side runner by oiling
Torque is transmitted to fluid power is carried out from the method on the runner of side.If no torque transmitting, machine oil are discharged intermediate space.However it is intermediate
Certain torque still can be transmitted by the vortex of the air between two runners when space empties, connecing for transmission device can be made
It is rotated from the component of side.In order to be switched to junior's mechanical transmission grade, must be able to brake with determining operating status from side.Institute
It states rotor brake for this provision, connect indirectly with the slave side axle of Hydrodynamic transmission component and it is possible thereby to brakes and consolidate
It holds from side.
Junior's mechanical transmission grade can be switched in halted state or when the revolving speed from side is low.For this purpose, having
The mechanical shifting element of teeth portion is made up of the teeth portion of axial movement and the transmission components that should switch to be rabbeted；This structure
The mode of making is, for example, jaw clutch.Can occur institute between shifting element and transmission components there is a situation where being herein
Meaning sets tooth position, that is two teeth portion are not embedded in mutually, and tooth laterally bumps against, and make it impossible to normally switch.It is this
State must be identified to, and handoff procedure must be interrupted and completely repeat, this expends the time very much.It then just can only be very
Normal running under power is carried out slowly.
Summary of the invention
The technical problem to be solved in the present invention is that provide it is a kind of suitable, for the rotor brake of hydraulic power unit
Simplified and reliable shift may be implemented without unnecessary time delay in device device.
It is above-mentioned for device the technical issues of solved according to the present invention by design scheme according to the invention.It is set this
Rotor brake gear is configured in meter scheme, and the brake bush can be transported to application position first from initial position
Dynamic, rotor brake is open in the initial position, and the brake bush described in the application position
Contacted with the rotating element, then can be moved along the circumferencial direction of rotating element under conditions of keeping the contact one section away from
From, wherein thus rotating element can be moved correspondingly together.Thus design scheme according to the invention provides advantage, rotation
Element can be not only braked by the manipulation of rotor brake, can also additionally along the circumferential direction be moved to a certain extent.
If tooth position is set in appearance, rotor brake only must be deactivated and be enabled to alternative expression several times, smoothly to realize the mutual of shift
Insertion.Real application of shift process, the i.e. axial force on shifting element need not be interrupted thus.Once transporting in the circumferential direction
Dynamic to proceed to the degree for releasing and setting to tooth position, then shifting element is automatically moved into the teeth portion of transmission components.
According to the distribution and shape of to be switched teeth portion, the length moved in the circumferential direction and/or shift when it is automatic
The quantity of the enabling rotor brake of implementation can be designed different.Enable-deactivate with control, especially in rotor brake-more
In the case where the corresponding design for the quantity replaced, good reliability may be implemented, allow to cancel for detecting normal shift
Sensor.This and it is hitherto known, with for checking that the sensor of drive range being set before discharge tractive force
Meter scheme differently provides additional cost advantage.
Clamping element can directly or indirectly pass through the intermediary element of one or more conductance, such as thick stick
Bar, connecting component or the like act on brake bush.Clamping element for example can be with fluid pressure type, pneumatic type, electricity
Magnetic-type or electric form required power.
For rotor brake control substantially there are two types of different working methods:
One is normally opened principle: here, rotor brake is not enabled when rotating element is static.I.e. brake friction serves as a contrast
Piece is not contacted with rotating element, and rotor brake is to open.The original in the rotor brake device compressed with fluid pressure type
Reason is primarily adapted for use in system and just forms the pressure for being used for hydraulic system by drive dynamics in operation.
Another kind is normally closed principle: here, rotor brake is closed when rotating element is static, brake bush patch
It leans against on rotating element and holds rotating element.If being switched to running under power, the pressure on clamping element is reduced, with
So that brake bush is moved from rotating element and opens rotor brake.It is right in the case where fluid pressure type compresses
The system needed for the principle can irrelevantly generate the pressure in hydraulic system with drive dynamics.
The brake bush refers to be formed with rotating element contacting and is suitable for generating for making
Dynamic frictional force.The material magnetic that for example, especially nonmagnetic metal or synthetic resin connect suitable for brake bush
Property metal or sintered friction material made of, dipping tissue.
Design scheme according to the invention it is further it is advantageous, make rotor brake device simpler, more reliable
Or more favorable feature is in the dependent claims.
In particular, rotor brake device can be structured as, clamping element can not only control brake friction facing from first
Beginning position to application position movement, moreover it is possible to control move in the circumferential direction.Thus second actuator is just no longer needed, this
So that construction more advantageous, more save space and can more simply control.
In particular it is preferred that rotor brake device has the lever with brake bush, the branch for lever
Point and guide member for fulcrum, fulcrum can move in guide member.Rotor brake device is configured to, in rotor brake
Rotation when enabling by lever around fulcrum allows brake bush to enter application position from initial position.It compresses
Element is thus conducted power to lever on active position.If pressing force continues to act on, fulcrum can move in guide member
It is dynamic, so that brake bush can carry out the movement of the circumferencial direction along rotating element.Here, rotating element passes through
The movement is correspondingly along the circumferential direction servo-actuated.It can be particularly simple and be reliably achieved rotor brake by this lever mechanism
Expected additional function.It can also can be with the brake force and brake bush being applied on rotating element by lever
The motion profile of completion is targetedly influenced from design aspect.Furthermore, it is possible to realize a possibility that simple for brake
It resets.
In particular, lever can be configured such that the active position of hydraulic cylinder is remoter than brake bush apart from fulcrum.
Brake force is improved thus relative to the power on lever is applied to by clamping element.Alternatively, lever also can be configured such that
Active position is more closely arranged on fulcrum than brake bush.It is possible thereby to realize brake bush to rotation member
The movement of part is greater than the movement corresponding to pure movement routine of the piston in hydraulic cylinder.
In advantageous design scheme, guide member is present on lever and fulcrum is embodied as and is used for rotor brake
The pin or pin that support construction is permanently connected.Alternatively, fulcrum may be embodied as the pin being permanently connected with lever
Or pin, guide member can reside in support construction.Rotor brake can be with by being considered as the component of support construction
Gear unit is permanently connected, so as to support compression power.Support construction for example can be a kind of brake casing or biography
A part of dynamic device housing.Or the channel plate (Kanalplatte) being present on gear unit can also be arranged as use
In the support construction of fulcrum.It is nonetheless contemplated that other embodiments.Being permanently connected, refer to conduct herein must
The power wanted.Guide member for example may be embodied as crack or empty slot, rail or slot or the like.
It is particularly advantageous guide member and is configured to substantially linear guide channel.This can particularly simple be manufactured.
What it is to the design scheme with lever is alternatively that rotor brake device can have sliding slot guide member, and sliding slot is led
Draw movement of the part guidance brake bush from initial position to application position to move in the circumferential direction with it.Thus may be used
To realize the function of the device according to the invention with simpler and reliable way.
Especially advantageous embodiment is, clamping element be embodied as the actuator of linear effect, be preferably implemented as it is hydraulic
Cylinder.Relative to electromagnetic type rotor brake, hydraulic cylinder is used as to exist for the clamping element bring great advantage of rotor brake
In the oil circulation that can be used natively has is used to control.Thus electromagnetism of the rotor brake individually with consuming is eliminated
Formula control, and individual harness thus.The bigger shift motion of brake bush may be implemented by fluid pressure type control
The parameter of bigger pressing force, especially two is unrelated with magnet configurations.Only need one for control standard magnet valve, no longer need
The electromagnet specially to be adjusted to compress.It is substantially reduced required installation space simultaneously.It can produce by hydraulic cylinder than so far
Until the common higher pressing force of rotor brake and and then generate bigger brake force.Checking cylinder is known.Checking cylinder
With piston and shell, piston can move back and forth in the housing.Hydraulic cylinder is controlled by pressure chamber, hydraulic fluid can pass through
Supply line imports pressure chamber, to apply pressure on piston, for moving piston and applying pressing force.There are hydraulic cylinder and
The standard component of magnet valve, so that thus generating than the lower cost in individually designed and manufacture component.
Hydraulic cylinder by being embodied as double-acting cylinder can realize the reset of brake in an advantageous manner.This hydraulic cylinder
With second pressure room, second pressure room can fill hydraulic fluid, so that piston moves in opposite direction.According at which
The pressure generated in pressure chamber is higher, and brake can be enabled or be opened.Preferably, make to control in this case
With two magnet valves or suitable switching valve.
It also may be embodied as electromagnetic type clamping element in middle clamping element according to the embodiment of the present invention.
When rotor brake device is configured to the position of the power of clamping element and the brake force of brake bush
Position in application position when on the linear extended line towards rotating element at the angle less than 90 °, can be with advantageous
Mode realize brake bush along the movement of the circumferencial direction of rotating element.It is achieved in and is effectively applied on rotating element
It reinforces and the movement needed can be realized by lever mechanism and unique clamping element.
It is particularly advantageous there is also at least one reset element, an especially at least reset spring, rabbets in lever
Or on clamping element, allow rotor brake enable be cancelled when cause brake bush with circumferentially side
To the opposite movement of movement and/or return to initial position.Thus the pressure for example in the pressure chamber of pressure cylinder is lower than determination
Threshold value when so that brake bush moves away rotating element.It can thus be realized by the hydraulic cylinder of unilateral side effect
The purposive control of brake.There may also be multiple reset elements, such as one for resisting in initial position and braking
Movement between position, another is used to resist the movement of the circumferencial direction along rotating element.
Equally may exist a kind of reset element, is arranged so that lever or clamping element can be along rotating elements
Cause arrester close when direction movement and the thus pressure in pressure chamber are lower than determining threshold value.The formerly modification
In design scheme, brake is open in no application pressure, and in second of Variant Design scheme, brake is not having
It is closure when applying pressure.It for example can on the one hand be opened by the hydraulic cylinder of double-acting in second of Variant Design scheme
Brake, the pressing force needed on the other hand being generated to braking.
Rotor brake device according to the invention can be equipped by being particularly advantageous hydraulic power unit.Therefore the present invention
Also it is related to a kind of single with fluid clutch and/or fluid torque-converter and the rotation of the fluid power of at least one mechanical transmission grade
Member.When, there is no when oil, the runner for attaching rotor brake accordingly can be held and along the circumferential direction in intermediate space
Reverse a distance.If occurring the position tooth nipper (Zahn-vor-Zahn) in mechanical transmission grade, simple pine can be passed through
It opens and enables rotor brake again and make the switching element connecting with rotating element torsion to a certain degree, so that tooth comes before notch
With can move towards each other.It is possible thereby to realize the reliably switching to mechanical transmission grade.In rotor system according to the invention
Illustrate further advantage in the design scheme of dynamic device.In particular, mechanical transmission grade is for the same gear ratios the case where
The combination of the lower transfer or mechanical shift transmission mechanism or the two for changing rotation direction.
It is advantageous that when rotor brake can be acted directly on by its brake bush fluid clutch or
On the runner of person's fluid torque-converter.For this purpose, design scheme can be designed as, can be led to by the rotating element that rotor brake acts on
It crosses in fluid clutch or fluid torque-converter from the runner structure on side.
Alternatively it is advantageously possible to not rotated by the rotating element that rotor brake acts on by axis and/or gear stage
Ground and connecting from the runner on side in fluid clutch or fluid torque-converter.So that between the brake force of rotor brake
It is grounded and is conducted on runner.
It is particularly advantageous that gear unit is embodied as, rotor brake device has hydraulic cylinder as clamping element, rotor
Brake gear is integrated in the channel plate of hydraulic power unit.
Except above-mentioned advantage except through using hydraulic cylinder, by having there is implementation, hydraulic cylinder supply line collection
At further advantage is obtained in channel plate, control pressure or lubricant or work can be supplied to other actuated elements
Matter.Thus cancel the additional machine oil pipeline for controlling hydraulic cylinder.Only need other pipelines or pipeline in channel plate.It is logical
Guidance tape is connect with gear mechanism housing.Channel plate is embodied as being formed in the connection on the oil circuit in gear mechanism housing and thus
Ensure hydraulic fluid without interruption and corresponding reflux.Latching member, metering part or regulating part, example can be laid on channel plate
As magnet valve is used for different pipelines, such as control pipeline or subcycle.Cover board can be arranged in channel plate, and cover board covers and seals
Ground closed channel and supply line.By the design scheme of this multi-piece type channel plate is simply manufactured.
It is particularly advantageous to be completely integrated in channel plate when the supply line for being used to control hydraulic cylinder.Here, not only liquid
The supply unit of pressure fluid is arranged in channel plate, and the pressure chamber on the piston of hydraulic cylinder also is disposed in channel plate.By
This is obtained without too multipart particularly simple design scheme.It is also possible to the only a part collection of supply line according to the present invention
At in channel plate.
By being integrated in hydraulic cylinder in channel plate, channel plate bears enabling the brake force applied when braking, because
Clamping element is supported on channel plate.Channel plate is used as the support construction for brake assemblies.Correspondingly, channel plate must be abundant
It designs and is securely fixed on gear mechanism housing.Rotor brake device can be pre-installed on channel plate and conduct
Unit and channel plate are installed, this is very big simplification.In order to control rotor brake, there is preferably have magnet valve, magnet valve control
Supply of the hydraulic fluid into pressure chamber or the pressure in pressure chamber.
Preferably, hydraulic cylinder has shell, which completely or at least partially passes through channel plate structure.It is exactly
It says, piston is imported into channel plate and/or pressure chamber at least partially through channel plate structure.This brings construction very simple excellent
Point.
Extraly or alternatively, hydraulic cylinder can have sliding sleeve, and sliding sleeve is completely or at least partially
It is integrated in channel plate.The piston of guiding hydraulic cylinder in the sliding sleeve.Manufacture can be made to use by using sliding sleeve
The recessed portion must be accurately processed in channel plate itself in the surface quality ratio of guiding and sealing piston to be easier.
Furthermore there may be there is holder, it is a part of hydraulic cylinder and constitutes piston and can move back and forth wherein
Shell at least part, holder connect with channel plate.Thus the hydraulic cylinder with longer piston also can be used, without
Channel plate must be made to be designed especially thick in installation site.
Additional design and installation caused by the rotor brake being kept completely separate are also eliminated to expend.According to existing
The usually relative extra consumption of technology is fairly expensive, because rotor brake is only once in a while and in less operation
It is required in state.The rotor brake being kept completely separate also needs additional installation space.In solution according to the invention
In, there is no the components being externally mounted on gear mechanism housing, and there is no the individual shells for rotor brake.
For the method for controlling the hydraulic power unit with rotor brake device according to the invention, feature
It is to implement following step:
A) rotating element being preferably freely rotated is braked by enabling rotor brake device,
B) pass through rotor brake device along the circumferential direction rotational-torsional element,
C) gearshift for being used for mechanical transmission grade is enabled,
Preferably, step b) is carried out after step a).Before or after step b) or period can all carry out step
c).Torsion additional by rotating element, determining can set obstruction shift to tooth position to avoid tooth.Lot of advantages is in rotor
Illustrate in brake gear.In the case where suitably selected movement routine in the circumferential direction, a disposable movement is just
It is enough.Be freely rotated refer to rotating element no longer initiatively by drive train, such as engine driving and acceleration, but base
Only pass through effect of inertia or the action as described above by the hydraulic transmission system component having been drained off in sheet.
It is particularly advantageous extraly successively to execute following step:
D) rotor brake device is deactivated,
E) rotor brake device is reactivated and with this rotational-torsional element again,
Wherein, the gearshift for mechanical transmission grade keeps enabling during this period.That is once there is no to tooth
Position, shifting element just automatically slide into the teeth portion of actuated element.It may be implemented by the repetition along the circumferential direction bigger
Movement routine.
In particular, step d) and e) disposable or repeat in multiple times.Gearshift also preferably keeps enabling herein, just
It is to say that axial force continues to act on shifting element, this makes shifting element in switching normal when not setting to tooth position.Cause
A kind of control for example can be implemented in this, results in smooth shift under any circumstance, regardless of the tooth when shift process starts
In which kind of position.It can cancel and monitor successfully shift and the sensor confirmed to control.
