Description
Technical field
The present invention relates to a kind of method that is used for regulating the exact filling level of the cooling medium in the cool cycles of Motor Vehicle, especially the cooling medium tank, wherein, the cooling medium that is used to cool off drive motor and/or other equipment is realized circulation.At this, in cool cycles, be provided with hydraulic retarder, the working medium of this hydraulic retarder is the cooling medium of cool cycles.
Background technique
Such cool cycles is open in the prior art repeatedly.Usually, in order to brake, realize that in cool cycles the part of circuit cooling medium is introduced in the active chamber that is made of main impeller (rotor) and time impeller (stator) by means of hydraulic retarder.Depend on the amount (degree of filling) that is in the cooling medium in the active chamber as working medium, torque is delivered on time impeller from main impeller with fluid power more or less, thus, the driving wheel or the drive motor of main impeller and the Motor Vehicle that is attached thereto are braked.
If Motor Vehicle for example to stop in order parking and just to have operated hydraulic retarder before this, after motor vehicles parking, in the active chamber of hydraulic retarder, also keep the working medium of certain residual capacity so.This residual capacity for example can be to depend on the retarding torque that just needs, and then is to depend on retrostage selected, that set by the driver on speed change lever.But this also means, the amount that promptly is retained in the residue working medium in the active chamber of retarder after docking process also is different according to different docking process.
Especially when considering the amount that detects the whole cooling medium that exists in the coolant system in other words in cool cycles, just for example when reading the cooling medium liquid level in the reservoir vessel, the working medium in the retarder this uncertain residual capacity of cooling medium in other words is disadvantageous.If after each docking process, monitor the liquid level of cooling medium, so because the residual capacity that keeps in retarder will obtain insecure measurement result with respect to the cooling medium deposit of reality.In other words, this means, can not whether in cool cycles/coolant system, lack cooling medium or have sufficient cooling medium accurately by measuring in the cooling medium liquid level that is commonly called liquid level owing to the amount of the cooling medium that in retarder, exists.This causes the danger of the filling overfill of coolant system in other words of Motor Vehicle cool cycles.
Summary of the invention
The objective of the invention is to avoid the defective that occurs in the prior art.At this, should take such measure, thereby can not rely on hydraulic retarder and whether be used to braking by the cooling medium liquid level in other words of the liquid level in reservoir vessel especially, accurately determine the amount of cooling medium to be replenished, and do not have the danger of filling overfill.
Purpose of the present invention realizes by independent claims.Dependent claims has provided particularly advantageous mode of execution of the present invention.
The method according to this invention is used for regulating the exact filling level of cooling medium of the cool cycles of Motor Vehicle, wherein, be used to cool off the cooling medium realization circulation of drive motor and/or other equipment, wherein, in cool cycles, be provided with hydraulic retarder, this hydraulic retarder comprises driven main impeller and time impeller, it is planar that these two impellers constitute annulus jointly, but optionally can fill active chamber with the emptying working medium, thereby torque is delivered on time impeller from main impeller with fluid power, wherein, the cooling medium of cool cycles also is the working medium of hydraulic retarder simultaneously; This method has following steps: moment (unmittelbar vor) before the docking process of Motor Vehicle is about to begin and/or finishes or the moment after and then the docking process of Motor Vehicle begins and/or finishes (unmittelbar nach) or during the docking process of beginning and/or Machine for tying filamentary material motor-car, the active chamber of hydraulic retarder is always with the amount of identical predetermined work medium, fully or almost entirely fill or emptying fully always with working medium especially always.The end of docking process is not meant the end of the dead time of Motor Vehicle at this, and is meant the end of this process so that Motor Vehicle subsequently for a long time or short period ground stop.
This means that the active chamber of retarder always is in identical liquid level in beginning or when finishing docking process, whether do not brake hope in current existence or once existed and rely on.All the time identical liquid level can realize thus according to the present invention, promptly sets the amount of identical working medium in the active chamber of retarder all the time, and the active chamber of retarder is filled up all the time fully or the active chamber of retarder is emptied completely all the time.Yet, when the active chamber of hydraulic retarder is especially favourable during all the time by complete filling, as next also will further describing.
Work as motor vehicles parking, and and then just just before the docking process, during the docking process or just after docking process the time, in active chamber, automatically set the amount of desirable working medium, wherein, just after docking process the explanation end of dead time, but the end of stopping.
The beginning of docking process for example can by close or or cut-off point ignition circuit (igniter), activate parking device (for example parking brake), when Motor Vehicle has automatic transmission case/automatic transmission, " park " by the selection level of insertion gearbox or by other, show that need the stop signal of long period of Motor Vehicle realizes.But docking process also can begin by deexcitation or disconnection drive unit simply.
Moment before will stopping or the moment after and then stopping or the signal that shows beginning and/or finish docking process during stopping for example can be realized by the current location of the ignition key of detection in igniter.If this key enters into other positions from current position, so the active chamber of retarder just can before the rotation ignition key or during or just that is to say on the time lingeringly, after ignition key is rotated to next position or end position, be filled or emptying, thereby realize that desirable is identical liquid level always.
When the active chamber of retarder is filled fully or with the amount of identical predetermined working medium always when at motor vehicles parking, preferably emptying fully or empty to the amount of predetermined residue working medium when Starter motor-car once more of this active chamber so.Therefore retarder is pushed into cooling medium in the external refrigeration circulation of being seen by the angle of retarder and helps making up pressure in cooling system, and this is desirable.Another advantage is; when the active chamber of retarder is filled fully or with the working medium of prearranging quatity during at motor vehicles parking; when so-called " heat is shut down "; that is to say under the situation of the cooling medium of relatively hot or parts to be cooled; by retarder or its active chamber are poured into; pressure in the cool cycles is lowered and is avoided outside, and promptly the excess pressure valve that is provided with in cooling system usually is triggered, carries out exhaust and cooling medium is discharged.
Advantageously, the active chamber of hydraulic retarder is filled by means of filling device.
The active chamber of hydraulic retarder is advantageously filled by means of the overvoltage of working medium/cooling medium that work as gravitational pressure, in cool cycles.This means that retarder is arranged on aspect surveying other the lower position of parts that is used for the cooling medium guiding than cool cycles, especially is arranged on than being arranged in the lower position of reservoir vessel in the cool cycles, that be used for cooling medium.Therefore, only need open the passage of the active chamber that enters into retarder, and therefore, cooling medium flow in the active chamber of retarder because of gravity.Replacedly, retarder can certainly be arranged on one on position higher aspect the surveying, promptly this retarder is especially by opening passage and coming emptying by means of the gravity that acts on the working medium in the active chamber.
According to an interchangeable design proposal, the active chamber of hydraulic retarder is filled by means of the pneumatic overvoltage from the Motor Vehicle compressed air system.Thus, for example pressurized air just can be applied on the piston of film or especially cylinder, thereby working medium is pushed in the active chamber.According to come freely active chamber exhaust also can realize emptying by means of overvoltage, especially pneumatic overvoltage to hydraulic retarder.Yet in order to carry out free exhaust, alternative pressurized air also may use another kind of medium, for example steam.
According to another design proposal; the active chamber of hydraulic retarder drives main impeller and fills wherein drive motor or the shutdown after filling of the additional motor that is provided with by rotating by means of the drive motor of Motor Vehicle or by means of additional motor, for example motor that is provided with.At this, use a kind of swabbing effect by the corresponding design proposal of main impeller.
Yet, according to an interchangeable design proposal, also can use main impeller pump efficiency should, thereby make retarder or its active chamber interchangeable mode of execution according to the present invention come emptying, wherein, locking feeding pipeline correspondingly.When drive motor carries out work for this reason, so this motor also when the signal of its deexcitation occurring being used to making (for example by the cut-off point firearm) correspondingly the short time work on, as expecting, be filled or emptying until the active chamber of hydraulic retarder.
According to another design proposal, the active chamber of hydraulic retarder is filled or emptying by driving cooling medium pump, and cooling medium pump is arranged in the cool cycles, and wherein cooling medium pump can be shut down after filling process finishes at once.For example be contemplated that, cooling medium pump is not only by the drive motor of Motor Vehicle, and drive by other drive unit, for example drive, thereby the active chamber that makes retarder has been closed or also can also be filled or emptying during deexcitation at the drive motor of Motor Vehicle by motor.
The described mode of execution of filling process of the active chamber of the retarder that all are existing, basis is carried out when motor vehicles parking also can be employed basically, thereby, when motor vehicles parking, the active chamber of retarder is emptied completely always or empties to the amount of predetermined working medium according to an interchangeable design proposal of the present invention.For example can use pump from active chamber, to pump working medium, perhaps also can use gravity, thereby make working medium flow out active chamber.Can certainly come emptying active chamber pneumatically as previously described like that.
Description of drawings
Should the present invention schematically be described according to unique accompanying drawing now.Shown in the figure:
Fig. 1 is a schematic representation of using the Motor Vehicle cool cycles of the method according to this invention.
Embodiment
In Fig. 1, schematically show schematic representation according to the Motor Vehicle cool cycles 1 of a preferred implementation.Be provided with hydraulic retarder 3 in cool cycles 1, it comprises main impeller 4 and time impeller 5, and these impellers constitute the planar active chamber 6 of annulus.The cooling medium of cool cycles 1 also is the working medium of hydraulic retarder 3 at the same time.At this, inferior impeller 5 is designed to fix.Replacedly, retarder 3 also may be designed to the contrarotating retarder.Main impeller 4 drives in these auxiliary drive 12 rotations by speed changer 8, and this auxiliary drive is connected with the drive shaft of drive motor 2.Therefore, retarder 3 is designed to time retarder and comes Motor Vehicle is braked according to travelling speed.Replacedly, retarder also may be designed to main reducing gear certainly, and comes Motor Vehicle is braked according to motor rotary speed.
In addition, on the flow direction of cooling medium, see, in current situation, in cool cycles 1, be provided with ensuing parts successively continuously, from retarder 3 or its active chamber 6: retarder modulating valve 11, heat exchanger 13, cooling medium pump 7 and retarder inlet valve 10.Retarder inlet valve 10 and retarder modulating valve 11 are operated by means of filling control gear 9, thereby the degree of filling in the active chamber 6 of control and/or adjusting hydraulic retarder 3 is just controlled and/or regulated its filling or emptying.
In addition, in cool cycles 1, also be provided with drive motor 2, thermostat 14 and compensation vessel 15.
If hydraulic retarder 3 is activated by the driver now,, change the open cross-section of valve 10,11 so by filling control gear 9 retarding torque as required for example by operation speed change lever or brake petal.The cooling medium of cooling medium pump 7 current conveyings flows and enters into active chamber 6 through retarder inlet valve 10.If drive by auxiliary drive 12 rotations at this main impeller 4, torque just is delivered on the fixing inferior impeller 5 from main impeller 4 with fluid power so, makes the Motor Vehicle braking thus.
If now Motor Vehicle is stopped, that is to say the beginning docking process, so before the docking process of start of evolution car, during or fill hydraulic retarder 3 by means of the amount of predetermined working medium in very short time afterwards.This can for example be undertaken by existing filling control gear 9 on the one hand, and wherein on especially maximum retrostage, and when the filling process of the active chamber 6 of retarder 3 finished, drive motor 2 ability were by deexcitation with hydraulic retarder 3 " connections " for this device.Additional or replacedly; after shutting down, drive motor 2 also can drive cooling medium pump 7 by unshowned other drive unit, for example motor; thereby guarantee necessary overvoltage, to be used for especially filling hydraulic retarder 3 with filling control gear 9 common uses for the cooling medium in the cool cycles 1.
What can certainly consider is to fill the active chamber 6 of hydraulic retarder 3 after drive motor 2 is shut down by means of the gravitational pressure in compensation vessel 15.As Fig. 1 finding, compensation vessel is provided with highlyer than hydraulic retarder 3, thereby when for example being provided with corresponding feeding pipeline by retarder modulating valve 11 and/or retarder inlet valve 10, cooling medium is flow in the active chamber 6.Equally also be contemplated that, by means of the overvoltage in the cool cycles 1 Already in, for example fill hydraulic retarder 3 by the heat input of in the cooling medium of cool cycles 1, realizing before.
Replacedly also be contemplated that, a unshowned filling device is set, it is arranged in the cool cycles 1 and with active chamber 6 fluids guiding ground and is connected.Such filling device may for example be small-sized pump, and it also makes up necessary overvoltage in order to fill hydraulic retarder 3 after drive motor 2 is shut down.This small-sized pump for example may be also supplied with by energy accumulator or the overvoltage in the compressed air container of the compressed air system by Motor Vehicle pneumatically electrically.Filling device also may be made of piston cylinder units, wherein volume of cylinder advantageously basically with the volume of active chamber or corresponding with the constant residual capacity of active chamber.
Just drive away at Motor Vehicle (starting) before or in, advantageously be emptied completely hydraulic retarder 3 or it emptied to residual capacity.At this, the conveying effect of working medium by hydraulic retarder 3 flows under pressure in the cool cycles and helps making up pressure simultaneously in the common cool cycles 1 of the Motor Vehicle that starts.
If hydraulic retarder 3 is operated during travelling for more time, and Motor Vehicle stops therefrom, the overvoltage that exists in cool cycles 1 is because heat input former thereby may cause the operation of excess pressure valve for example makes cooling medium by cool cycles 1 with especially by discharge in the compensation vessel 15 thus so.If retarder is filled with the amount of predetermined working medium when docking process according to the present invention, has so just reduced the pressure in cool cycles 1, thereby can not cause the undesirable discharge and and then the loss of cooling medium of cooling medium.
Therefore, the present invention allows to be adjusted in cooling medium distribution in the cool cycles of Motor Vehicle in this wise by fill hydraulic retarder predeterminedly, promptly do not rely on retarder and whether between docking process, be operated, and always have predetermined liquid level (considering the amount that is included in the cooling medium in the retarder).This has facilitated and can directly identify the loss of cooling medium and compensate.
